When Does Different Types of Organ Damage From Lupus Occur? Long-Term Study Sheds Light
TOPLINE:
The first year after the diagnosis of systemic lupus erythematosus (SLE) is crucial, with the highest percentage of patients experiencing organ damage. Cardiovascular issues are the second most prevalent after musculoskeletal damage in both early and later stages of SLE.
METHODOLOGY:
- Researchers assessed organ damage persisting at least 6 months over different stages of lupus in 4219 patients with SLE (mean age, 35.9 years; 89.6% women) from the Spanish Society of Rheumatology Lupus Registry.
- Damage was assessed using the Systemic Lupus International Collaborating Clinics/American College of Rheumatology Damage Index (SDI).
- Longitudinal analysis was conducted globally and by each SDI domain on 1274 patients with recorded damage event dates.
- Follow-up data were available out to 10 years in 1113 patients and to 20 years in 601.
TAKEAWAY:
- New damage was recorded in 20% of the patients with SLE within the first year after diagnosis, with the annual percentage of patients with new damage decreasing to 5% after the first 5 years of follow-up.
- In the first year, musculoskeletal damage was reported by the highest proportion of patients (21%), followed by cardiovascular damage inclusive of cerebrovascular accidents and claudication for 6 months (19%).
- The cardiovascular system remained the second most affected system even during the later stages of the diseases at years 10 and 20 of follow-up (20%-25%).
- Apart from musculoskeletal and cardiovascular damage, patients with lupus also showed renal and ocular damage in the early and later stages of the disease, respectively.
IN PRACTICE:
“Our study highlights the importance of cardiovascular damage and the need for its prevention during the earliest stages of the disease,” the authors wrote.
SOURCE:
The study was led by Irene Altabás-González, MD, PhD, Rheumatology Department, Vigo University Hospital Group, Vigo, Spain. It was published online in Lupus Science & Medicine.
LIMITATIONS:
The retrospective collection of data in the study may have led to missing items; for example, the dates of damage events for the whole cohort were not available.
DISCLOSURES:
The registry was supported by the Spanish Society of Rheumatology. No specific funding was received for the study. The authors declared no conflicts of interest.

Psychiatric, Autoimmune Comorbidities Increased in Patients with Alopecia Areata
TOPLINE:
and were at greater risk of developing those comorbidities after diagnosis.
METHODOLOGY:
- Researchers evaluated 63,384 patients with AA and 3,309,107 individuals without AA (aged 12-64 years) from the Merative MarketScan Research Databases.
- The matched cohorts included 16,512 patients with AA and 66,048 control individuals.
- Outcomes were the prevalence of psychiatric and autoimmune diseases at baseline and the incidence of new-onset psychiatric and autoimmune diseases during the year after diagnosis.
TAKEAWAY:
- Overall, patients with AA showed a greater prevalence of any psychiatric disease (30.9% vs 26.8%; P < .001) and any immune-mediated or autoimmune disease (16.1% vs 8.9%; P < .0001) than those with controls.
- In matched cohorts, patients with AA also showed a higher incidence of any new-onset psychiatric diseases (10.2% vs 6.8%; P < .001) or immune-mediated or autoimmune disease (6.2% vs 1.5%; P <.001) within the first 12 months of AA diagnosis than those with controls.
- Among patients with AA, the risk of developing a psychiatric comorbidity was higher (adjusted hazard ratio [aHR], 1.3; 95% CI, 1.3-1.4). The highest risks were seen for adjustment disorder (aHR, 1.5), panic disorder (aHR, 1.4), and sexual dysfunction (aHR, 1.4).
- Compared with controls, patients with AA were also at an increased risk of developing immune-mediated or autoimmune comorbidities (aHR, 2.7; 95% CI, 2.5-2.8), with the highest for systemic lupus (aHR, 5.7), atopic dermatitis (aHR, 4.3), and vitiligo (aHR, 3.8).
IN PRACTICE:
“Routine monitoring of patients with AA, especially those at risk of developing comorbidities, may permit earlier and more effective intervention,” the authors wrote.
SOURCE:
The study was led by Arash Mostaghimi, MD, MPA, MPH, Brigham and Women’s Hospital and Harvard University, Boston. It was published online on July 31, 2024, in JAMA Dermatology.
LIMITATIONS:
Causality could not be inferred because of the retrospective nature of the study. Comorbidities were solely diagnosed on the basis of diagnostic codes, and researchers did not have access to characteristics such as lab values that could have indicated any underlying comorbidity before the AA diagnosis. This study also did not account for the varying levels of severity of the disease, which may have led to an underestimation of disease burden and the risk for comorbidities.

Sjögren Disease Treatments in Early Trials Have Mostly Positive Results
VIENNA — Nipocalimab, iscalimab, and tibulizumab, but not lusvertikimab, appear to be promising new agents for Sjögren disease that warrant further investigation, suggest the results of four separate early clinical trials reported at the recent annual European Congress of Rheumatology (EULAR).
This is potentially good news for patients, as discovering new treatments that work for managing the various symptoms of Sjögren disease is a high priority, Jacques-Eric Gottenberg, MD, PhD, said when he presented the results of the phase 2 DAHLIAS study of nipocalimab during a late-breaking abstract session.
“All patients suffer from high burden of symptoms — pain, fatigue, and dryness; nearly 50% of patients have systemic complications; mortality is increased, so there is a high unmet need since no specific drug has been accepted so far,” said Dr. Gottenberg, who works at Strasbourg University Hospital in Strasbourg, France.
“The pathogenesis of the disease involves high B-cell activation, resulting in high IgG levels, and secretion of autoantibodies,” such as anti-Ro, anti-La, anti-Sjögren’s syndrome type A (anti-SSA), and anti-Sjögren’s syndrome type B antibodies, Dr. Gottenberg said.
Thus, one approach to reducing the disease burden is to try to lower circulating immunoglobulin G (IgG) levels and IgG-associated autoantibodies, which is how the monoclonal antibody nipocalimab works. Nipocalimab essentially blocks the interaction of IgG with the neonatal fragment crystallizable receptor and has already been shown to have efficacy in other autoimmune conditions such as myasthenia gravis and fetal and neonatal hemolytic disease, although not as hoped in rheumatoid arthritis.
The DAHLIAS Phase 2 Study
Now, results from the DAHLIAS study show that nipocalimab may also work in Sjögren disease, with significant improvement vs placebo seen in the primary endpoint of the total EULAR Sjögren’s Syndrome Disease Activity Index (clinESSDAI) at 24 weeks for one of the two doses of the drug that were tested.
The multicenter, placebo-controlled, double-blind study was conducted in 163 patients with moderate to severely active primary Sjögren disease. The latter was determined by having a clinESSDAI of 6 or higher and seropositivity for anti-Ro60, anti-Ro52, or both autoantibodies.
Dr. Gottenberg reported that the mean age of patients was 48 years; the majority (92.6%) were women and of White ethnicity (90.8%). The baseline clinESSDAI was a mean of 9.9; 98.1% had anti-Ro60, 80.6% had anti-Ro52, and 71.9% had anti-La antibodies.
In addition to standard of care, patients were randomly allocated to receive intravenous treatment every 2 weeks with nipocalimab 5 mg/kg or 15 mg/kg, or placebo.
At 24 weeks, the least squares mean (LSM) change in clinESSDAI from baseline was −3.74 for placebo, −4.08 for nipocalimab 5 mg/kg (P = not significant vs placebo), and −6.40 for nipocalimab 15 mg/kg (P = .02 vs placebo).
Nipocalimab 15 mg/kg also “demonstrated similar and consistent trends in other key efficacy endpoints,” Dr. Gottenberg said. This included improvements in the ESSDAI and EULAR Sjögren’s Syndrome Patient Reported Index (ESSPRI) and composite measures such as the Sjögren’s Tool for Assessing Response (STAR), Composite of Relevant Endpoints for Sjögren’s Syndrome (CRESS), and the Disease Activity Level. There were also improvements in the unstimulated salivary flow rate.
Safety findings showed no new concerns, with adverse events reported in 62.5% of placebo-treated patients and by 79.2% and 79.6% of patients receiving nipocalimab 5 mg/kg and 15 mg/kg, respectively. Serious adverse events were reported in a respective 5.4%, 7.5%, and 7.4%, including severe infections or infections requiring intravenous anti-infectives in 1.8%, 3.8%, and 1.9% of participants, although none was thought to be related to the study treatment. No opportunistic infections or any deaths were reported.
Thomas Schindler, PhD, senior clinical scientist at F. Hoffmann-La Roche Ltd., in Basel, Switzerland, commented from the audience: “This was a very impressive set of results, and I’m very surprised that its safety profile is so benign.”
Dr. Schindler wanted to know if there were any changes in the serum albumin level and if this manifested as any laboratory abnormalities, but there were no reported cases of severe hypoalbuminemia in the study.
The TWINSS Phase 2 Study
Similarly hopeful results were reported for iscalimab, a fully human IgG1 anti-CD40 monoclonal antibody that is given by subcutaneous injection, during a clinical abstracts session. Xavier Mariette, MD, PhD, head of the Rheumatology Department at Bicêtre Hospital, Paris-Saclay University in Paris, France, reported updated results of the phase 2b dose-ranging TWINSS study, showing sustained benefits at 48 weeks. The primary endpoint results at 24 weeks were recently published in The Lancet.
TWINSS was set up to assess the safety and efficacy of iscalimab given every 2 weeks vs placebo in two distinct cohorts of patients with Sjögren disease — one with moderate to severe disease with both systemic and symptomatic involvement and the other with low systemic involvement but high symptom burden.
Whereas patients in the first cohort who had moderate to severe disease (n = 173) were randomly allocated to one of three doses (150, 300, and 600 mg) of iscalimab or placebo for the initial 24 weeks, those in the second cohort (n = 100) were randomly allocated to a 600-mg dose or placebo. After the double-blind period ended, patients taking iscalimab continued on the dose they were taking for another 24 weeks, with those in the placebo arms switching to the 600-mg dose in cohort 1 and the 300-mg dose in cohort 2.
Topline results for those in cohort 1 with moderate to severe Sjögren disease were that the significant improvements in ESSDAI that had been seen at week 24 were maintained in those who continued iscalimab and improved in those who had switched from placebo.
LSM change from baseline in ESSDAI vs placebo at week 24 had been −3.0, −1.4, and −2.9 for the 150-, 300-, and 600-mg doses of iscalimab, respectively. Results at week 48 were a respective −7.6, −5.7, and −7.9. The LSM change for the placebo-treated patients who had switched to the 600-mg dose was −6.7.
Dr. Mariette reported “consistent improvement” in patient-reported outcomes, including ESSPRI, the Sjögren’s Syndrome Symptom Diary, Functional Assessment of Chronic Illness Therapy-Fatigue measure, and the Impact of Dry Eye on Everyday Life instrument. There was also a significant improvement in stimulated salivary flow rates.
Similar benefits were seen in the second cohort of patients who did not have systemic involvement but had a high burden of symptoms, with improved ESSPRI scores of a LSM change from baseline vs placebo of −2.29 for patients continuing iscalimab 600 mg treatment and −1.14 for those taking the 300-mg dose after being treated with placebo. Improvements were also seen in the other patient-reported outcomes used.
Regarding safety, Dr. Mariette reported that there were “no specific issues” seen in the patients who switched from placebo to iscalimab, either at the 300-mg or 600-mg dose. Any adverse event occurred in around 80% of placebo-treated patients and roughly 90% of those given iscalimab, and serious adverse events occurred in 11.4%, 14.3%, and 11.4% pf patients treated with iscalimab 150, 300, and 600 mg, and 4.9% of those given placebo and then 600 mg iscalimab.
“The safety seems equivalent to patients having received iscalimab from the beginning of the trial,” Dr. Mariette said, adding “the risk-benefit [analysis] seems positive in patients up to week 48.”
Phase 1 Trial of Tibulizumab
Further positive early trial results were reported by Michael Howell, PhD, chief scientific officer for Zura Bio, a biotech company based in Henderson, Nevada. During a poster tour at EULAR 2024, Dr. Howell presented some preliminary findings from a phase 1 trial of tibulizumab, a dual antagonist of interleukin (IL)-17A and the B-cell–activating factor (BAFF) engineered by fusing elements of ixekizumab (Taltz) and tabalumab together.
“The headline result for me is that the molecule does what it’s supposed to,” Dr. Howell told this news organization. “We have potent engagement of the IL-17 and BAFF pathways, and this sets the tone for additional exploration in rheumatologic diseases where there’s known activation of those two pathways,” he said.
Dr. Howell reported that total B-cell counts and lower levels of type 1 T helper cells were seen during the trial.
Over the years, Dr. Howell, an immunologist, has been involved in the development of many therapeutics, such as risankizumab (Skyrizi) and spesolimab (Spevigo).
“When I look at the molecules and the opportunity we have to do broader antagonism of pathways in a safe aspect, this is probably one of the most exciting,” he said.
The trial he presented included 25 people with a confirmed diagnosis of Sjögren disease and anti-SSA or anti-SSB antibodies. Patients received tibulizumab or a placebo for a total of 12 weeks via a subcutaneous injection. Various doses were tested: 30 mg, 100 mg, or 300 mg every 4 weeks, or 300 mg every 2 weeks.
Serum levels of both BAFF and IL-17A increased as expected in the tibulizumab-treated patients, and Dr. Howell reported that “it’s well tolerated. There’s no adverse event profile that caused any concern.”
As a phase 1 study, it was not powered to look at efficacy, but there were positive signals, Dr. Howell said, meaning that the drug is likely to be tested further in a phase 2 trial.
Lusvertikimab Phase 2 Trial
During the same poster tour, the null findings of a phase 2 trial of the anti-IL-7 monoclonal antibody lusvertikimab were presented by Benjamin Fisher, MD, professor of rheumatology at Birmingham University in Birmingham, England.
Dr. Fisher told this news organization: “It’s a negative study, at least over the 3-month period that we’ve studied it.” Whether longer durations of treatment may be needed is a question that currently cannot be answered, he added.
A total of 48 patients with Sjögren disease had been included in the trial from 19 different centers in Europe, the United States, and Australia. The mean age of the participants was 53.7 years, 87% were women, and the mean duration of disease was 5.0 years. Baseline ESSDAI and ESSPRI were 12.1 and 7.0, respectively. Half were receiving other background treatment, and 72.9% were anti-Ro or anti-SSA positive.
Lusvertikimab 750 mg or a matching placebo was given via intravenous infusion at weeks 0, 2, 4, 7, and 10.
The primary endpoint was the mean change in ESSDAI from baseline to week 13, which was the same, at −3.9, in both groups. There was also no significant difference between the groups in any of the other secondary endpoints that were used, including ESSPRI, Schirmer’s test, the ocular staining score, salivary flow rate, physician and patient global assessment, assessment of fatigue, quality of life, or the composite measures STAR and CRESS.
“This isn’t going anywhere,” said Dr. Fisher, asking what was going to happen next and if this meant the end of IL-7-focused therapy.
“For years, there’s been quite a lot of interest in this,” Dr. Fisher said. Sjögren disease is characterized by a sort of focal inflammation of the saliva glands, which is composed of both T and B cells in the early stages, probably a T-cell component and a B-cell component, he explained.
“IL-7 is thought to be an important cytokine for homeostasis of the T-cell compartment, so for maintenance of T central memory and effector memory cells,” he said. “So, the idea is that, if you block IL-7, you switch off T cells, and you may rebalance the immune system towards a more regulatory phenotype. Just that it didn’t work,” Dr. Fisher said.
“There’s large unmet need,” he said. “Sjögren’s is associated with poor health-related quality of life, [and] a large part that is symptom-driven — dryness and fatigue — which we have no real interventions yet for patients; there’s no licensed therapeutics for it.”
Dr. Fisher cited ianalumab as one of the front-runners for becoming the first licensed treatment for Sjögren disease. The novel BAFF-targeting antibody is already in phase 3 trials and is also showing promise for the treatment of systemic lupus erythematosus.
“Then there are CD40-targeting drugs; the ones most advanced are dazodalibep and iscalimab.” Commenting on the potential of iscalimab, Dr. Fisher said that it “seems to work — it improves systemic disease activity; it also leads to some symptomatic improvement, which has been difficult to demonstrate in Sjögren’s.”
Dr. Fisher added that “the nipocalimab data looks interesting, as do data on TYK2 inhibition.”
The DAHLIAS study was funded by Janssen Research & Development. Dr. Gottenberg has consulted for AbbVie, Bristol Myers Squibb (BMS), Galapagos, Gilead, Janssen, Lilly, Merck Sharp & Dohme, Novartis, Pfizer, Sanofi, and UCB. The TWINSS study was funded by Novartis. Dr. Mariette has consulted for BMS, Galapagos, GlaxoSmithKline, Novartis, Pfizer, and Servier. The tibulizumab phase 1 study was funded by Eli Lilly & Company. Dr. Howell is an employee of the developer, Zura Bio. The Institut de Recherches Internationales Servier sponsored the lusvertikimab trial. Dr. Fisher has consulted for Novartis, Roche, BMS, Galapagos, Janssen, Servier, UCB, and Sanofi and received funding to his institution for collaborative research from Janssen, Celgene, Galapagos, and Servier.

At 24 weeks, the least squares mean (LSM) change in clinESSDAI from baseline was −3.74 for placebo, −4.08 for nipocalimab 5 mg/kg (P = not significant vs placebo), and −6.40 for nipocalimab 15 mg/kg (P = .02 vs placebo).
Nipocalimab 15 mg/kg also “demonstrated similar and consistent trends in other key efficacy endpoints,” Dr. Gottenberg said. This included improvements in the ESSDAI and EULAR Sjögren’s Syndrome Patient Reported Index (ESSPRI) and composite measures such as the Sjögren’s Tool for Assessing Response (STAR), Composite of Relevant Endpoints for Sjögren’s Syndrome (CRESS), and the Disease Activity Level. There were also improvements in the unstimulated salivary flow rate.
Safety findings showed no new concerns, with adverse events reported in 62.5% of placebo-treated patients and by 79.2% and 79.6% of patients receiving nipocalimab 5 mg/kg and 15 mg/kg, respectively. Serious adverse events were reported in a respective 5.4%, 7.5%, and 7.4%, including severe infections or infections requiring intravenous anti-infectives in 1.8%, 3.8%, and 1.9% of participants, although none was thought to be related to the study treatment. No opportunistic infections or any deaths were reported.
Thomas Schindler, PhD, senior clinical scientist at F. Hoffmann-La Roche Ltd., in Basel, Switzerland, commented from the audience: “This was a very impressive set of results, and I’m very surprised that its safety profile is so benign.”
Dr. Schindler wanted to know if there were any changes in the serum albumin level and if this manifested as any laboratory abnormalities, but there were no reported cases of severe hypoalbuminemia in the study.
The TWINSS Phase 2 Study
Similarly hopeful results were reported for iscalimab, a fully human IgG1 anti-CD40 monoclonal antibody that is given by subcutaneous injection, during a clinical abstracts session. Xavier Mariette, MD, PhD, head of the Rheumatology Department at Bicêtre Hospital, Paris-Saclay University in Paris, France, reported updated results of the phase 2b dose-ranging TWINSS study, showing sustained benefits at 48 weeks. The primary endpoint results at 24 weeks were recently published in The Lancet.
TWINSS was set up to assess the safety and efficacy of iscalimab given every 2 weeks vs placebo in two distinct cohorts of patients with Sjögren disease — one with moderate to severe disease with both systemic and symptomatic involvement and the other with low systemic involvement but high symptom burden.
Whereas patients in the first cohort who had moderate to severe disease (n = 173) were randomly allocated to one of three doses (150, 300, and 600 mg) of iscalimab or placebo for the initial 24 weeks, those in the second cohort (n = 100) were randomly allocated to a 600-mg dose or placebo. After the double-blind period ended, patients taking iscalimab continued on the dose they were taking for another 24 weeks, with those in the placebo arms switching to the 600-mg dose in cohort 1 and the 300-mg dose in cohort 2.
Topline results for those in cohort 1 with moderate to severe Sjögren disease were that the significant improvements in ESSDAI that had been seen at week 24 were maintained in those who continued iscalimab and improved in those who had switched from placebo.
LSM change from baseline in ESSDAI vs placebo at week 24 had been −3.0, −1.4, and −2.9 for the 150-, 300-, and 600-mg doses of iscalimab, respectively. Results at week 48 were a respective −7.6, −5.7, and −7.9. The LSM change for the placebo-treated patients who had switched to the 600-mg dose was −6.7.
Dr. Mariette reported “consistent improvement” in patient-reported outcomes, including ESSPRI, the Sjögren’s Syndrome Symptom Diary, Functional Assessment of Chronic Illness Therapy-Fatigue measure, and the Impact of Dry Eye on Everyday Life instrument. There was also a significant improvement in stimulated salivary flow rates.
Similar benefits were seen in the second cohort of patients who did not have systemic involvement but had a high burden of symptoms, with improved ESSPRI scores of a LSM change from baseline vs placebo of −2.29 for patients continuing iscalimab 600 mg treatment and −1.14 for those taking the 300-mg dose after being treated with placebo. Improvements were also seen in the other patient-reported outcomes used.
Regarding safety, Dr. Mariette reported that there were “no specific issues” seen in the patients who switched from placebo to iscalimab, either at the 300-mg or 600-mg dose. Any adverse event occurred in around 80% of placebo-treated patients and roughly 90% of those given iscalimab, and serious adverse events occurred in 11.4%, 14.3%, and 11.4% pf patients treated with iscalimab 150, 300, and 600 mg, and 4.9% of those given placebo and then 600 mg iscalimab.
“The safety seems equivalent to patients having received iscalimab from the beginning of the trial,” Dr. Mariette said, adding “the risk-benefit [analysis] seems positive in patients up to week 48.”
Phase 1 Trial of Tibulizumab
Further positive early trial results were reported by Michael Howell, PhD, chief scientific officer for Zura Bio, a biotech company based in Henderson, Nevada. During a poster tour at EULAR 2024, Dr. Howell presented some preliminary findings from a phase 1 trial of tibulizumab, a dual antagonist of interleukin (IL)-17A and the B-cell–activating factor (BAFF) engineered by fusing elements of ixekizumab (Taltz) and tabalumab together.
“The headline result for me is that the molecule does what it’s supposed to,” Dr. Howell told this news organization. “We have potent engagement of the IL-17 and BAFF pathways, and this sets the tone for additional exploration in rheumatologic diseases where there’s known activation of those two pathways,” he said.
Dr. Howell reported that total B-cell counts and lower levels of type 1 T helper cells were seen during the trial.
Over the years, Dr. Howell, an immunologist, has been involved in the development of many therapeutics, such as risankizumab (Skyrizi) and spesolimab (Spevigo).
“When I look at the molecules and the opportunity we have to do broader antagonism of pathways in a safe aspect, this is probably one of the most exciting,” he said.
The trial he presented included 25 people with a confirmed diagnosis of Sjögren disease and anti-SSA or anti-SSB antibodies. Patients received tibulizumab or a placebo for a total of 12 weeks via a subcutaneous injection. Various doses were tested: 30 mg, 100 mg, or 300 mg every 4 weeks, or 300 mg every 2 weeks.
Serum levels of both BAFF and IL-17A increased as expected in the tibulizumab-treated patients, and Dr. Howell reported that “it’s well tolerated. There’s no adverse event profile that caused any concern.”
As a phase 1 study, it was not powered to look at efficacy, but there were positive signals, Dr. Howell said, meaning that the drug is likely to be tested further in a phase 2 trial.
Lusvertikimab Phase 2 Trial
During the same poster tour, the null findings of a phase 2 trial of the anti-IL-7 monoclonal antibody lusvertikimab were presented by Benjamin Fisher, MD, professor of rheumatology at Birmingham University in Birmingham, England.
Dr. Fisher told this news organization: “It’s a negative study, at least over the 3-month period that we’ve studied it.” Whether longer durations of treatment may be needed is a question that currently cannot be answered, he added.
A total of 48 patients with Sjögren disease had been included in the trial from 19 different centers in Europe, the United States, and Australia. The mean age of the participants was 53.7 years, 87% were women, and the mean duration of disease was 5.0 years. Baseline ESSDAI and ESSPRI were 12.1 and 7.0, respectively. Half were receiving other background treatment, and 72.9% were anti-Ro or anti-SSA positive.
Lusvertikimab 750 mg or a matching placebo was given via intravenous infusion at weeks 0, 2, 4, 7, and 10.
The primary endpoint was the mean change in ESSDAI from baseline to week 13, which was the same, at −3.9, in both groups. There was also no significant difference between the groups in any of the other secondary endpoints that were used, including ESSPRI, Schirmer’s test, the ocular staining score, salivary flow rate, physician and patient global assessment, assessment of fatigue, quality of life, or the composite measures STAR and CRESS.
“This isn’t going anywhere,” said Dr. Fisher, asking what was going to happen next and if this meant the end of IL-7-focused therapy.
“For years, there’s been quite a lot of interest in this,” Dr. Fisher said. Sjögren disease is characterized by a sort of focal inflammation of the saliva glands, which is composed of both T and B cells in the early stages, probably a T-cell component and a B-cell component, he explained.
“IL-7 is thought to be an important cytokine for homeostasis of the T-cell compartment, so for maintenance of T central memory and effector memory cells,” he said. “So, the idea is that, if you block IL-7, you switch off T cells, and you may rebalance the immune system towards a more regulatory phenotype. Just that it didn’t work,” Dr. Fisher said.
“There’s large unmet need,” he said. “Sjögren’s is associated with poor health-related quality of life, [and] a large part that is symptom-driven — dryness and fatigue — which we have no real interventions yet for patients; there’s no licensed therapeutics for it.”
Dr. Fisher cited ianalumab as one of the front-runners for becoming the first licensed treatment for Sjögren disease. The novel BAFF-targeting antibody is already in phase 3 trials and is also showing promise for the treatment of systemic lupus erythematosus.
“Then there are CD40-targeting drugs; the ones most advanced are dazodalibep and iscalimab.” Commenting on the potential of iscalimab, Dr. Fisher said that it “seems to work — it improves systemic disease activity; it also leads to some symptomatic improvement, which has been difficult to demonstrate in Sjögren’s.”
Dr. Fisher added that “the nipocalimab data looks interesting, as do data on TYK2 inhibition.”
The DAHLIAS study was funded by Janssen Research & Development. Dr. Gottenberg has consulted for AbbVie, Bristol Myers Squibb (BMS), Galapagos, Gilead, Janssen, Lilly, Merck Sharp & Dohme, Novartis, Pfizer, Sanofi, and UCB. The TWINSS study was funded by Novartis. Dr. Mariette has consulted for BMS, Galapagos, GlaxoSmithKline, Novartis, Pfizer, and Servier. The tibulizumab phase 1 study was funded by Eli Lilly & Company. Dr. Howell is an employee of the developer, Zura Bio. The Institut de Recherches Internationales Servier sponsored the lusvertikimab trial. Dr. Fisher has consulted for Novartis, Roche, BMS, Galapagos, Janssen, Servier, UCB, and Sanofi and received funding to his institution for collaborative research from Janssen, Celgene, Galapagos, and Servier.

VIENNA — Nipocalimab, iscalimab, and tibulizumab, but not lusvertikimab, appear to be promising new agents for Sjögren disease that warrant further investigation, suggest the results of four separate early clinical trials reported at the recent annual European Congress of Rheumatology (EULAR).
This is potentially good news for patients, as discovering new treatments that work for managing the various symptoms of Sjögren disease is a high priority, Jacques-Eric Gottenberg, MD, PhD, said when he presented the results of the phase 2 DAHLIAS study of nipocalimab during a late-breaking abstract session.
“All patients suffer from high burden of symptoms — pain, fatigue, and dryness; nearly 50% of patients have systemic complications; mortality is increased, so there is a high unmet need since no specific drug has been accepted so far,” said Dr. Gottenberg, who works at Strasbourg University Hospital in Strasbourg, France.
“The pathogenesis of the disease involves high B-cell activation, resulting in high IgG levels, and secretion of autoantibodies,” such as anti-Ro, anti-La, anti-Sjögren’s syndrome type A (anti-SSA), and anti-Sjögren’s syndrome type B antibodies, Dr. Gottenberg said.
Thus, one approach to reducing the disease burden is to try to lower circulating immunoglobulin G (IgG) levels and IgG-associated autoantibodies, which is how the monoclonal antibody nipocalimab works. Nipocalimab essentially blocks the interaction of IgG with the neonatal fragment crystallizable receptor and has already been shown to have efficacy in other autoimmune conditions such as myasthenia gravis and fetal and neonatal hemolytic disease, although not as hoped in rheumatoid arthritis.
The DAHLIAS Phase 2 Study
Now, results from the DAHLIAS study show that nipocalimab may also work in Sjögren disease, with significant improvement vs placebo seen in the primary endpoint of the total EULAR Sjögren’s Syndrome Disease Activity Index (clinESSDAI) at 24 weeks for one of the two doses of the drug that were tested.
The multicenter, placebo-controlled, double-blind study was conducted in 163 patients with moderate to severely active primary Sjögren disease. The latter was determined by having a clinESSDAI of 6 or higher and seropositivity for anti-Ro60, anti-Ro52, or both autoantibodies.
Dr. Gottenberg reported that the mean age of patients was 48 years; the majority (92.6%) were women and of White ethnicity (90.8%). The baseline clinESSDAI was a mean of 9.9; 98.1% had anti-Ro60, 80.6% had anti-Ro52, and 71.9% had anti-La antibodies.
In addition to standard of care, patients were randomly allocated to receive intravenous treatment every 2 weeks with nipocalimab 5 mg/kg or 15 mg/kg, or placebo.
At 24 weeks, the least squares mean (LSM) change in clinESSDAI from baseline was −3.74 for placebo, −4.08 for nipocalimab 5 mg/kg (P = not significant vs placebo), and −6.40 for nipocalimab 15 mg/kg (P = .02 vs placebo).
Nipocalimab 15 mg/kg also “demonstrated similar and consistent trends in other key efficacy endpoints,” Dr. Gottenberg said. This included improvements in the ESSDAI and EULAR Sjögren’s Syndrome Patient Reported Index (ESSPRI) and composite measures such as the Sjögren’s Tool for Assessing Response (STAR), Composite of Relevant Endpoints for Sjögren’s Syndrome (CRESS), and the Disease Activity Level. There were also improvements in the unstimulated salivary flow rate.
Safety findings showed no new concerns, with adverse events reported in 62.5% of placebo-treated patients and by 79.2% and 79.6% of patients receiving nipocalimab 5 mg/kg and 15 mg/kg, respectively. Serious adverse events were reported in a respective 5.4%, 7.5%, and 7.4%, including severe infections or infections requiring intravenous anti-infectives in 1.8%, 3.8%, and 1.9% of participants, although none was thought to be related to the study treatment. No opportunistic infections or any deaths were reported.
Thomas Schindler, PhD, senior clinical scientist at F. Hoffmann-La Roche Ltd., in Basel, Switzerland, commented from the audience: “This was a very impressive set of results, and I’m very surprised that its safety profile is so benign.”
Dr. Schindler wanted to know if there were any changes in the serum albumin level and if this manifested as any laboratory abnormalities, but there were no reported cases of severe hypoalbuminemia in the study.
The TWINSS Phase 2 Study
Similarly hopeful results were reported for iscalimab, a fully human IgG1 anti-CD40 monoclonal antibody that is given by subcutaneous injection, during a clinical abstracts session. Xavier Mariette, MD, PhD, head of the Rheumatology Department at Bicêtre Hospital, Paris-Saclay University in Paris, France, reported updated results of the phase 2b dose-ranging TWINSS study, showing sustained benefits at 48 weeks. The primary endpoint results at 24 weeks were recently published in The Lancet.
TWINSS was set up to assess the safety and efficacy of iscalimab given every 2 weeks vs placebo in two distinct cohorts of patients with Sjögren disease — one with moderate to severe disease with both systemic and symptomatic involvement and the other with low systemic involvement but high symptom burden.
Whereas patients in the first cohort who had moderate to severe disease (n = 173) were randomly allocated to one of three doses (150, 300, and 600 mg) of iscalimab or placebo for the initial 24 weeks, those in the second cohort (n = 100) were randomly allocated to a 600-mg dose or placebo. After the double-blind period ended, patients taking iscalimab continued on the dose they were taking for another 24 weeks, with those in the placebo arms switching to the 600-mg dose in cohort 1 and the 300-mg dose in cohort 2.
Topline results for those in cohort 1 with moderate to severe Sjögren disease were that the significant improvements in ESSDAI that had been seen at week 24 were maintained in those who continued iscalimab and improved in those who had switched from placebo.
LSM change from baseline in ESSDAI vs placebo at week 24 had been −3.0, −1.4, and −2.9 for the 150-, 300-, and 600-mg doses of iscalimab, respectively. Results at week 48 were a respective −7.6, −5.7, and −7.9. The LSM change for the placebo-treated patients who had switched to the 600-mg dose was −6.7.
Dr. Mariette reported “consistent improvement” in patient-reported outcomes, including ESSPRI, the Sjögren’s Syndrome Symptom Diary, Functional Assessment of Chronic Illness Therapy-Fatigue measure, and the Impact of Dry Eye on Everyday Life instrument. There was also a significant improvement in stimulated salivary flow rates.
Similar benefits were seen in the second cohort of patients who did not have systemic involvement but had a high burden of symptoms, with improved ESSPRI scores of a LSM change from baseline vs placebo of −2.29 for patients continuing iscalimab 600 mg treatment and −1.14 for those taking the 300-mg dose after being treated with placebo. Improvements were also seen in the other patient-reported outcomes used.
Regarding safety, Dr. Mariette reported that there were “no specific issues” seen in the patients who switched from placebo to iscalimab, either at the 300-mg or 600-mg dose. Any adverse event occurred in around 80% of placebo-treated patients and roughly 90% of those given iscalimab, and serious adverse events occurred in 11.4%, 14.3%, and 11.4% pf patients treated with iscalimab 150, 300, and 600 mg, and 4.9% of those given placebo and then 600 mg iscalimab.
“The safety seems equivalent to patients having received iscalimab from the beginning of the trial,” Dr. Mariette said, adding “the risk-benefit [analysis] seems positive in patients up to week 48.”

Lusvertikimab 750 mg or a matching placebo was given via intravenous infusion at weeks 0, 2, 4, 7, and 10.
The primary endpoint was the mean change in ESSDAI from baseline to week 13, which was the same, at −3.9, in both groups. There was also no significant difference between the groups in any of the other secondary endpoints that were used, including ESSPRI, Schirmer’s test, the ocular staining score, salivary flow rate, physician and patient global assessment, assessment of fatigue, quality of life, or the composite measures STAR and CRESS.

FROM EULAR 2024
Air Pollution and Genetics May Raise Risk for Lupus
TOPLINE:
Chronic exposure to air pollutants such as fine particulate matter ≤ 2.5 μm in diameter (PM2.5), particulate matter ≤ 10 μm in diameter (PM10), nitrogen dioxide (NO2), and nitrogen oxides (NOX) increased the risk for systemic lupus erythematosus (SLE) onset. The risk was highest among those with high genetic risk and high air-pollution exposure.
METHODOLOGY:
- Researchers prospectively investigated the association between long-term exposure to air pollutants and incident SLE in 459,815 participants from the UK Biobank.
- A land-use regression model was used to quantify the annual average air pollution concentrations, including PM2.5, PM10, NO2, and NOX.
- The genetic susceptibility to lupus was assessed using polygenic risk scores (PRS), and the participants were classified into low–, intermediate–, or high–genetic-risk groups based on the tertiles of PRS.
- The joint effect of air pollutants and genetic susceptibility to lupus on the risk for incident SLE was evaluated, with the reference group consisting of participants with a low genetic risk and low exposure to air pollution.
TAKEAWAY:
- Over a median follow-up period of 11.77 years, 399 new cases of SLE were identified.
- The odds of developing SLE were higher among participants with high genetic risk than among those with low genetic risk (hazard ratio [HR], 3.45; P < .001 for trend).
- The risk for developing SLE was even higher among participants with a high genetic risk and high exposure to PM2.5 (adjusted HR [aHR], 4.16; 95% CI, 2.67-6.49), PM10 (aHR, 5.31; 95% CI, 3.30-8.55), NO2 (aHR, 5.61; 95% CI, 3.45-9.13), and NOX (aHR, 4.80; 95% CI, 3.00-7.66) than among with those with a low genetic risk and low exposure to air pollutants.
IN PRACTICE:
“Findings can inform the development of stricter air quality regulations to mitigate exposure to harmful pollutants, thereby reducing the risk of SLE,” the authors wrote.
SOURCE:
The study was led by Meiqi Xing, MASc, Huazhong University of Science and Technology, Wuhan, China. It was published online in Arthritis & Rheumatology.
LIMITATIONS:
The study participants were enrolled voluntarily, which may have led to selection bias because they might have been healthier or more health conscious. The study did not consider the specific components of air pollutants, particularly particulate matter, which may have varying effects on the incidence of SLE. Other air pollutants such as ozone, sulfur dioxide, and carbon monoxide were not included in the analysis.
DISCLOSURES:
This study did not disclose any funding source. The authors declared no conflicts of interest.

- The risk for developing SLE was even higher among participants with a high genetic risk and high exposure to PM2.5 (adjusted HR [aHR], 4.16; 95% CI, 2.67-6.49), PM10 (aHR, 5.31; 95% CI, 3.30-8.55), NO2 (aHR, 5.61; 95% CI, 3.45-9.13), and NOX (aHR, 4.80; 95% CI, 3.00-7.66) than among with those with a low genetic risk and low exposure to air pollutants.
IN PRACTICE:
“Findings can inform the development of stricter air quality regulations to mitigate exposure to harmful pollutants, thereby reducing the risk of SLE,” the authors wrote.

Future of Lupus Treatments Looks Brighter With Multiple Promising Therapeutic Approaches
VIENNA — It may have been a while since there have been any major breakthroughs in the treatment of systemic lupus erythematosus (SLE), but there are high hopes that this is a situation that may be about to change, experts agreed at the annual European Congress of Rheumatology.
“It’s an incredibly vivid area of development,” Laurent Arnaud, MD, PhD, professor of rheumatology at the University of Strasbourg in Strasbourg, France, said during one of the first sessions of the meeting. He reported that there were at least 17 phase 2 and 14 phase 3 trials that were expected to start within the next few years, all with investigational agents that target different immune cells or pathways that have been implicated in the pathogenesis of SLE.
In a systematic review published last year, Dr. Arnaud and coauthors found that there were 92 investigational biologic or novel targeted agents in various phases of clinical testing. This included B-cell–targeting agents such as ianalumab, plasma cell-targeting agents such as daratumumab, and drugs with novel mechanisms of action such as KPG-818, which targets the CRL4-Cereblon (CRBN) E3 ubiquitin ligase complex. Phase 2 data on all three of these investigational agents were presented during various sessions at EULAR 2024, all with positive results, suggesting that their further development in SLE is worth pursuing.
There are of course “many more candidates in the pipeline,” Dr. Arnaud said. “I’m very happy that I think we are going to see great days for lupus right in front of our eyes.”
Targeting B Cells
Drugs that target B cells have been at the forefront of lupus treatment for several years, as David Isenberg, MD, professor of rheumatology at University College London, pointed out during an interview for EULAR TV.
“It’s clearly important to target the cells which are likely to be causing the problem in lupus, and in the main, that tends to be B cells,” he said.
Dr. Isenberg, who is renowned for his work with the B-cell–targeting agent rituximab, added: “But we know that obviously T cells integrate with B cells, so anything which interrupts the link between the T cell and the B cell is likely to be important.”
Chimeric Antigen Receptor (CAR) T-Cell Therapy ‘Revolution’
One new way of targeting B cells is with CAR T-cell therapy, which David D’Cruz , MD, PhD, a consultant rheumatologist for Guy’s and St. Thomas’ Hospital NHS Foundation Trust in London, picked as one of the “most striking” topics highlighted at EULAR 2024.
This is “truly personalized medicine,” Dr. D’Cruz said. This is an autologous therapy because a patient’s T cells are removed by leukapheresis, transfected with a CAR T vector directed against a component of the B cell, and then returned to them.
“I do feel that we’re on the cusp of a major revolution,” Dr. D’Cruz told this news organization. Not only in lupus but also in other rheumatic conditions that have proved really difficult to treat, such as systemic sclerosis and myositis, he said.
“Basically, it’s a very powerful B-cell–depleting tool, but it’s much more profound B-cell–depleting tool than, for example, rituximab or belimumab,” explained Dr. D’Cruz. “What you’re doing is reprogramming T cells to attack the B cells.”
Although rituximab and belimumab clear all the B cells in the circulation, there are still some cells left behind in the bone marrow, “and it’s very difficult to get rid of those,” Dr. D’Cruz said. “What CAR T-cell therapy appears to do is wipe out all the CD19-positive B cells everywhere, in the blood and the tissue. So you get a really profound B-cell depletion.”
Eric Morand, MBBS, PhD, head of rheumatology at Monash Health in Melbourne, Australia, told this news organization that there was obviously “a lot of buzz” about CAR T-cell therapy.
“We’re waiting to see if the exciting data from Erlangen can be reproduced in other centers with other CAR T products to show that it is a universal effect. We haven’t seen that yet, but I think we will by next year.”
Cost and expertise are two major considerations and potential limiting factors, however, as Dr. D’Cruz and Dr. Isenberg both pointed out in separate interviews with this news organization.
Dr. D’Cruz said: “It’s very expensive, it takes a while, and it doesn’t always work is what I’m hearing. It’s usually successful, but again, a little bit depends on the technique and the people doing the process.”
Dr. Isenberg said: “CAR T-cell therapy is, I think, very exciting because it does look to be quite promising. But as it costs 350,000 euros per patient, I don’t think that it is going to be widely adopted.”
Even if it could be afforded by certain centers in the West, he added, this just would not be feasible in poorer nations. “So, we’ve got to find other effective, cheaper ways to go,” Dr. Isenberg said.
“I think there are some very interesting ideas with monoclonal antibodies which target at least two different targets — one on the B cell, one on the T cell — and that could well be the way to take this forward,” he suggested.
Ianalumab ‘Double Blocking’ B Cells
Another way could be to develop more potent B-cell–depleting drugs, as Nancy Agmon-Levin , MD, head of the Clinical Immunology, Angioedema and Allergy Unit, Lupus and Autoimmune Diseases Clinic, at Sheba Medical Center, Tel Aviv University in Tel Aviv, Israel, reported during one of the clinical abstract sessions at EULAR 2024.
Dr. Agmon-Levin presented data on 67 individuals with SLE who had participated in a multicenter phase 2 study of ianalumab, a fully human immunoglobulin (Ig) G1 monoclonal antibody that results in a “double blocking of the B-cell lineage.”
Ianalumab targets the B-cell–activating factor receptor (BAFFR), but what makes it distinct from other BAFF-targeting drugs is that it has had a fructose molecule removed from its Fc portion, which renders it more likely to trigger antibody-dependent cellular cytotoxicity.
“This is a B-cell depletion therapy,” Agmon-Levin said, but it also blocks BAFFR-mediated survival of B cells, so the subsequent recuperation process of BAFFR-expressing B cells is affected, leading to continued B-cell depletion.
The phase 2 study she presented consisted of an initial 28-week, double-blind period, during which time participants had been randomly allocated to receive either subcutaneous injections of ianalumab 300 mg or a matching placebo every 4 weeks. This was followed by a 24-week, open-label period where all participants were treated with ianalumab, and then an off-treatment, minimal follow-up period that lasted up to 68 weeks, with continued data collection for safety.
The primary outcome measure was a composite of meeting criteria for the SLE Responder Index 4 and a sustained reduction in corticosteroid use at 28 weeks. This was achieved in 15 of the 34 (44.1%) people treated with ianalumab vs only 3 (9.1%) of the 33 people who had been given a placebo.
Dr. Agmon-Levin reported that the effect on this outcome was sustained to the end of the open-label period, at 1 year, in 15 (45.5%) of 33 participants who had continued treatment with ianalumab and achieved in 13 (40.6%) of 32 participants who had switched from placebo to ianalumab treatment.
Moreover, longer durations of treatment were associated with a host of improved outcomes, Dr. Agmon-Levin said: “Treatment was improved along the 52 weeks, and we can see from the LLDAS [Lupus Low Disease Activity State], DORIS [Definition Of Remission In SLE], and SRI-6 and -8 that as you continue the therapy, you improve the outcomes.”
The potential benefits of ianalumab in the treatment of SLE and lupus nephritis will now be further examined in the phase 3 SIRIUS-SLE1 , SIRIUS-SLE2, and SIRIUS-LN trials, which are estimated to provide initial results in 2027 and complete in early 2029 or 2030.
Targeting Plasma Cells With Daratumumab
Another drug showing signs that it might be useful as a treatment for SLE is daratumumab, as Tobias Alexander, MD, of Charité — Universitätsmedizin Berlin, reported during one of the late-breaking abstract sessions at EULAR 2024.
“Daratumumab is a human, first-in-class anti-CD38 antibody that efficiently depletes plasma cells,” Dr. Alexander said. CD38 is both a receptor and an enzyme, and while it is found on the surface of most immune cells, it’s particularly expressed by plasma cells, he added.
Daratumumab is not a total newcomer, however, as it’s already approved for the treatment of multiple myeloma under the trade name Darzalex. The rationale for using it in SLE comes from two case reports, Dr. Alexander explained. The first, published in 2020 in The New England Journal of Medicine, involved two patients with severe and life-threatening lupus who were given off-label treatment for a period of 4 weeks and experienced good clinical and serologic responses. The second, published last year in Nature Medicine, involved six patients with refractory lupus nephritis, five of whom had a clinical response at 6 months.
“On this background, we conducted an investigator-initiated trial, which was an open-label, single-center, proof-of-concept study,” Dr. Alexander said. A total of 10 female patients whose ages ranged from 24 to 43 years were included in the phase 2 trial that was dubbed DARALUP. For inclusion, all had to have a Systemic Lupus Erythematosus Disease Activity Index 2000 (SLEDAI-2K) of four or more for clinical manifestations, have been treated with at least two prior disease-modifying drugs to no avail, and be anti–double-stranded DNA (anti-dsDNA) antibody positive. Dr. Alexander reported that the median baseline SLEDAI-2K score was 12 and ranged from 8 to 20, with the number of prior therapies ranging from two to nine.
Daratumumab was given at a dose of 1800 mg via subcutaneous injection every week for 8 weeks. This is the same dose that is used to treat multiple myeloma, Dr. Alexander explained, although the dosing is not stopped. The reason for stopping after 8 weeks in the current trial was to be able to see what happened once the treatment was stopped. The follow-up was for 36 weeks.
Dr. Alexander reported that there was a “very dramatic and significant” effect on the primary endpoint of a reduction in anti-dsDNA antibody levels, decreasing from a median of 166.3 U/mL at baseline to 61.1 U/mL at week 12 (P = .002). Alongside, there was a reduction in the SLEDAI-2K score from 12 to 4 within 12 weeks, which was sustained at the 36-week follow-up assessment. Improvements in skin, joint, kidney, and level of proteinuria were also seen.
Although all patients experienced adverse events, none were serious. Infections and infestations (mostly nasopharyngitis, COVID-19, and gastroenteritis) were the most common, experienced by 80% of the participants; 70% had injection site reactions or fatigue, 60% had gastrointestinal symptoms, 50% had a fall of IgG < 5 g/L, 40% had headache, and 20% had back pain.
“This is a positive trial. I think we could demonstrate that [daratumumab] produced very strong, rapid, and durable clinical improvements,” Dr. Alexander said. “We think that targeting CD38 is relevant; plasma cells had been depleted based on the reduction of anti-dsDNA antibodies,” he added.
From the audience, however, Peter Nash, MBBS, of Griffith University in Brisbane, Australia, questioned whether the results could be attributed to “a steroid effect” because patients had been treated with oral dexamethasone throughout the study.
Dr. Alexander noted that steroid use had been part of the treatment schedule but acknowledged it was a possible confounder.
“I think we can be confident that [daratumumab] had a major effect on plasma cells decreasing…because we see that also the vaccine titers decreased,” Dr. Alexander said. “Time will tell, but even more important is the durability of the responses over time, which you don’t achieve under steroids.”
KPG-818’s Novel Mechanism of Action
Elsewhere at EULAR 2024, positive results of another phase 2 study involving a drug with an entirely different mechanism of action, KPG-818, were reported in a poster presentation. KPG-818 modulates CRBN, which results in the degradation of two transcription factors (Aiolos and Ikaros) that are involved in the development, maturation, and proliferation of innate and adaptive immune cells and have been linked to genetic risk in SLE, according to the poster’s authors. It is currently in development for the treatment of SLE, Behçet disease, inflammatory bowel disease, multiple myeloma, and non-Hodgkin lymphoma.
Yao Wang, MD, chief medical officer of KPG-818’s developer Kangpu Biopharmaceuticals, Hefei, China, and associates found that oral doses of 0.15 or 0.6 mg KPG-818 were “generally well-tolerated” and produced immunomodulatory changes that could be beneficial in people with SLE over a 12-week treatment period.
“Only two new agents have been approved for the treatment of SLE in the past five decades in USA and Europe,” Dr. Wang and team wrote, which highlights “a significant unmet need for more effective and safe treatment options.”
They believe that KPG-818 might well fit the bill based on the results of their study, in which 35 of 37 recruited patients completed the treatment. Compared with placebo, they observed reduced numbers of total B cells, Aiolos+ T and B cells, and increased Treg cells.
SLEDAI-2K and Cutaneous Lupus Erythematosus Disease Area and Severity Index activity scores in the 0.15-mg group were improved relative to baseline and placebo.
“The proof-of-concept findings suggest a favorable benefit/risk ratio in SLE for KPG-818,” Dr. Wang and coauthors said, supporting its further development in SLE.
Need for Treatments
Dr. Isenberg told this news organization that both daratumumab and KPG-818 would be welcome additions as treatment options if further trials proved their worth.
“The great frustration about lupus is that, compared to patients with rheumatoid arthritis, the choice has been so limited,” Dr. Isenberg said. Aside from rituximab (Rituxan) and belimumab (Benlysta), which are used with certain restrictions, there are no other biologic targeted treatments available in the United Kingdom. Anifrolumab (Saphnelo) has a license in the United States and some European countries but is not yet available for him to use in his practice.
Daratumumab and KPG-818 are “different types of molecules, and if they work that will be great. It would be nice to have the choice,” Dr. Isenberg said. “Whether they will be as effective as I think rituximab is, I don’t know, but these are some very encouraging results.”
Of course, these are all phase 2 trials, and the “big problem” is that such positive results do not always translate when it comes to phase 3, as Dr. D’Cruz told this news organization.
“Until a few years ago, there had been about 25 or 30 industry-led trails, and they’d all failed, except for belimumab and anifrolumab,” Dr. D’Cruz said. These drugs were found to work and be generally safe in phase 1 and 2 trials, but “when they come to phase 3, they all seem to fail, and we don’t know why.”
These are large global studies, D’Cruz added, observing that problems with patient selection, steroid use, and choice of outcome measures were possible factors for why the EXPLORER and LUNAR studies had shown no benefit for rituximab despite the drug being widely used to treat SLE.
Dr. Isenberg, who has coauthored an article on the topic of why drugs seem to fail at the final hurdle, noted: “I think it has a lot to do with the nature of the disease. It’s a complicated disease.” From having “savvy physicians doing the trials for you” to the placebo response, there are “a whole bunch or reasons why these things haven’t worked in lupus.”
Dr. Morand commented: “We’ve got many programs in phase 2 and 3, and because there’s so many, they’re all facing recruitment challenges, and as a consequence of so much activity, every program is going a little slower than hoped for.”
As for other drugs on the horizon, Dr. Morand noted: “We’re very optimistic about things like litifilimab and deucravacitinib; that’s two examples that are in phase 3. Earlier in the program of development, [there are] a huge range of targets being addressed. The future looks bright. But we might have to wait a while.”

Dr. D’Cruz said: “It’s very expensive, it takes a while, and it doesn’t always work is what I’m hearing. It’s usually successful, but again, a little bit depends on the technique and the people doing the process.”
Dr. Isenberg said: “CAR T-cell therapy is, I think, very exciting because it does look to be quite promising. But as it costs 350,000 euros per patient, I don’t think that it is going to be widely adopted.”
Even if it could be afforded by certain centers in the West, he added, this just would not be feasible in poorer nations. “So, we’ve got to find other effective, cheaper ways to go,” Dr. Isenberg said.

KPG-818’s Novel Mechanism of Action
Elsewhere at EULAR 2024, positive results of another phase 2 study involving a drug with an entirely different mechanism of action, KPG-818, were reported in a poster presentation. KPG-818 modulates CRBN, which results in the degradation of two transcription factors (Aiolos and Ikaros) that are involved in the development, maturation, and proliferation of innate and adaptive immune cells and have been linked to genetic risk in SLE, according to the poster’s authors. It is currently in development for the treatment of SLE, Behçet disease, inflammatory bowel disease, multiple myeloma, and non-Hodgkin lymphoma.
Yao Wang, MD, chief medical officer of KPG-818’s developer Kangpu Biopharmaceuticals, Hefei, China, and associates found that oral doses of 0.15 or 0.6 mg KPG-818 were “generally well-tolerated” and produced immunomodulatory changes that could be beneficial in people with SLE over a 12-week treatment period.

SLEDAI-2K and Cutaneous Lupus Erythematosus Disease Area and Severity Index activity scores in the 0.15-mg group were improved relative to baseline and placebo.
“The proof-of-concept findings suggest a favorable benefit/risk ratio in SLE for KPG-818,” Dr. Wang and coauthors said, supporting its further development in SLE.
Need for Treatments
Dr. Isenberg told this news organization that both daratumumab and KPG-818 would be welcome additions as treatment options if further trials proved their worth.
“The great frustration about lupus is that, compared to patients with rheumatoid arthritis, the choice has been so limited,” Dr. Isenberg said. Aside from rituximab (Rituxan) and belimumab (Benlysta), which are used with certain restrictions, there are no other biologic targeted treatments available in the United Kingdom. Anifrolumab (Saphnelo) has a license in the United States and some European countries but is not yet available for him to use in his practice.
Daratumumab and KPG-818 are “different types of molecules, and if they work that will be great. It would be nice to have the choice,” Dr. Isenberg said. “Whether they will be as effective as I think rituximab is, I don’t know, but these are some very encouraging results.”
Of course, these are all phase 2 trials, and the “big problem” is that such positive results do not always translate when it comes to phase 3, as Dr. D’Cruz told this news organization.
“Until a few years ago, there had been about 25 or 30 industry-led trails, and they’d all failed, except for belimumab and anifrolumab,” Dr. D’Cruz said. These drugs were found to work and be generally safe in phase 1 and 2 trials, but “when they come to phase 3, they all seem to fail, and we don’t know why.”
These are large global studies, D’Cruz added, observing that problems with patient selection, steroid use, and choice of outcome measures were possible factors for why the EXPLORER and LUNAR studies had shown no benefit for rituximab despite the drug being widely used to treat SLE.
Dr. Isenberg, who has coauthored an article on the topic of why drugs seem to fail at the final hurdle, noted: “I think it has a lot to do with the nature of the disease. It’s a complicated disease.” From having “savvy physicians doing the trials for you” to the placebo response, there are “a whole bunch or reasons why these things haven’t worked in lupus.”
Dr. Morand commented: “We’ve got many programs in phase 2 and 3, and because there’s so many, they’re all facing recruitment challenges, and as a consequence of so much activity, every program is going a little slower than hoped for.”
As for other drugs on the horizon, Dr. Morand noted: “We’re very optimistic about things like litifilimab and deucravacitinib; that’s two examples that are in phase 3. Earlier in the program of development, [there are] a huge range of targets being addressed. The future looks bright. But we might have to wait a while.”

VIENNA — It may have been a while since there have been any major breakthroughs in the treatment of systemic lupus erythematosus (SLE), but there are high hopes that this is a situation that may be about to change, experts agreed at the annual European Congress of Rheumatology.
“It’s an incredibly vivid area of development,” Laurent Arnaud, MD, PhD, professor of rheumatology at the University of Strasbourg in Strasbourg, France, said during one of the first sessions of the meeting. He reported that there were at least 17 phase 2 and 14 phase 3 trials that were expected to start within the next few years, all with investigational agents that target different immune cells or pathways that have been implicated in the pathogenesis of SLE.
In a systematic review published last year, Dr. Arnaud and coauthors found that there were 92 investigational biologic or novel targeted agents in various phases of clinical testing. This included B-cell–targeting agents such as ianalumab, plasma cell-targeting agents such as daratumumab, and drugs with novel mechanisms of action such as KPG-818, which targets the CRL4-Cereblon (CRBN) E3 ubiquitin ligase complex. Phase 2 data on all three of these investigational agents were presented during various sessions at EULAR 2024, all with positive results, suggesting that their further development in SLE is worth pursuing.
There are of course “many more candidates in the pipeline,” Dr. Arnaud said. “I’m very happy that I think we are going to see great days for lupus right in front of our eyes.”
Targeting B Cells
Drugs that target B cells have been at the forefront of lupus treatment for several years, as David Isenberg, MD, professor of rheumatology at University College London, pointed out during an interview for EULAR TV.
“It’s clearly important to target the cells which are likely to be causing the problem in lupus, and in the main, that tends to be B cells,” he said.
Dr. Isenberg, who is renowned for his work with the B-cell–targeting agent rituximab, added: “But we know that obviously T cells integrate with B cells, so anything which interrupts the link between the T cell and the B cell is likely to be important.”
Chimeric Antigen Receptor (CAR) T-Cell Therapy ‘Revolution’
One new way of targeting B cells is with CAR T-cell therapy, which David D’Cruz , MD, PhD, a consultant rheumatologist for Guy’s and St. Thomas’ Hospital NHS Foundation Trust in London, picked as one of the “most striking” topics highlighted at EULAR 2024.
This is “truly personalized medicine,” Dr. D’Cruz said. This is an autologous therapy because a patient’s T cells are removed by leukapheresis, transfected with a CAR T vector directed against a component of the B cell, and then returned to them.
“I do feel that we’re on the cusp of a major revolution,” Dr. D’Cruz told this news organization. Not only in lupus but also in other rheumatic conditions that have proved really difficult to treat, such as systemic sclerosis and myositis, he said.
“Basically, it’s a very powerful B-cell–depleting tool, but it’s much more profound B-cell–depleting tool than, for example, rituximab or belimumab,” explained Dr. D’Cruz. “What you’re doing is reprogramming T cells to attack the B cells.”
Although rituximab and belimumab clear all the B cells in the circulation, there are still some cells left behind in the bone marrow, “and it’s very difficult to get rid of those,” Dr. D’Cruz said. “What CAR T-cell therapy appears to do is wipe out all the CD19-positive B cells everywhere, in the blood and the tissue. So you get a really profound B-cell depletion.”
Eric Morand, MBBS, PhD, head of rheumatology at Monash Health in Melbourne, Australia, told this news organization that there was obviously “a lot of buzz” about CAR T-cell therapy.
“We’re waiting to see if the exciting data from Erlangen can be reproduced in other centers with other CAR T products to show that it is a universal effect. We haven’t seen that yet, but I think we will by next year.”
Cost and expertise are two major considerations and potential limiting factors, however, as Dr. D’Cruz and Dr. Isenberg both pointed out in separate interviews with this news organization.
Dr. D’Cruz said: “It’s very expensive, it takes a while, and it doesn’t always work is what I’m hearing. It’s usually successful, but again, a little bit depends on the technique and the people doing the process.”
Dr. Isenberg said: “CAR T-cell therapy is, I think, very exciting because it does look to be quite promising. But as it costs 350,000 euros per patient, I don’t think that it is going to be widely adopted.”
Even if it could be afforded by certain centers in the West, he added, this just would not be feasible in poorer nations. “So, we’ve got to find other effective, cheaper ways to go,” Dr. Isenberg said.
“I think there are some very interesting ideas with monoclonal antibodies which target at least two different targets — one on the B cell, one on the T cell — and that could well be the way to take this forward,” he suggested.
Ianalumab ‘Double Blocking’ B Cells
Another way could be to develop more potent B-cell–depleting drugs, as Nancy Agmon-Levin , MD, head of the Clinical Immunology, Angioedema and Allergy Unit, Lupus and Autoimmune Diseases Clinic, at Sheba Medical Center, Tel Aviv University in Tel Aviv, Israel, reported during one of the clinical abstract sessions at EULAR 2024.
Dr. Agmon-Levin presented data on 67 individuals with SLE who had participated in a multicenter phase 2 study of ianalumab, a fully human immunoglobulin (Ig) G1 monoclonal antibody that results in a “double blocking of the B-cell lineage.”
Ianalumab targets the B-cell–activating factor receptor (BAFFR), but what makes it distinct from other BAFF-targeting drugs is that it has had a fructose molecule removed from its Fc portion, which renders it more likely to trigger antibody-dependent cellular cytotoxicity.
“This is a B-cell depletion therapy,” Agmon-Levin said, but it also blocks BAFFR-mediated survival of B cells, so the subsequent recuperation process of BAFFR-expressing B cells is affected, leading to continued B-cell depletion.
The phase 2 study she presented consisted of an initial 28-week, double-blind period, during which time participants had been randomly allocated to receive either subcutaneous injections of ianalumab 300 mg or a matching placebo every 4 weeks. This was followed by a 24-week, open-label period where all participants were treated with ianalumab, and then an off-treatment, minimal follow-up period that lasted up to 68 weeks, with continued data collection for safety.
The primary outcome measure was a composite of meeting criteria for the SLE Responder Index 4 and a sustained reduction in corticosteroid use at 28 weeks. This was achieved in 15 of the 34 (44.1%) people treated with ianalumab vs only 3 (9.1%) of the 33 people who had been given a placebo.
Dr. Agmon-Levin reported that the effect on this outcome was sustained to the end of the open-label period, at 1 year, in 15 (45.5%) of 33 participants who had continued treatment with ianalumab and achieved in 13 (40.6%) of 32 participants who had switched from placebo to ianalumab treatment.
Moreover, longer durations of treatment were associated with a host of improved outcomes, Dr. Agmon-Levin said: “Treatment was improved along the 52 weeks, and we can see from the LLDAS [Lupus Low Disease Activity State], DORIS [Definition Of Remission In SLE], and SRI-6 and -8 that as you continue the therapy, you improve the outcomes.”
The potential benefits of ianalumab in the treatment of SLE and lupus nephritis will now be further examined in the phase 3 SIRIUS-SLE1 , SIRIUS-SLE2, and SIRIUS-LN trials, which are estimated to provide initial results in 2027 and complete in early 2029 or 2030.
Targeting Plasma Cells With Daratumumab
Another drug showing signs that it might be useful as a treatment for SLE is daratumumab, as Tobias Alexander, MD, of Charité — Universitätsmedizin Berlin, reported during one of the late-breaking abstract sessions at EULAR 2024.
“Daratumumab is a human, first-in-class anti-CD38 antibody that efficiently depletes plasma cells,” Dr. Alexander said. CD38 is both a receptor and an enzyme, and while it is found on the surface of most immune cells, it’s particularly expressed by plasma cells, he added.
Daratumumab is not a total newcomer, however, as it’s already approved for the treatment of multiple myeloma under the trade name Darzalex. The rationale for using it in SLE comes from two case reports, Dr. Alexander explained. The first, published in 2020 in The New England Journal of Medicine, involved two patients with severe and life-threatening lupus who were given off-label treatment for a period of 4 weeks and experienced good clinical and serologic responses. The second, published last year in Nature Medicine, involved six patients with refractory lupus nephritis, five of whom had a clinical response at 6 months.
“On this background, we conducted an investigator-initiated trial, which was an open-label, single-center, proof-of-concept study,” Dr. Alexander said. A total of 10 female patients whose ages ranged from 24 to 43 years were included in the phase 2 trial that was dubbed DARALUP. For inclusion, all had to have a Systemic Lupus Erythematosus Disease Activity Index 2000 (SLEDAI-2K) of four or more for clinical manifestations, have been treated with at least two prior disease-modifying drugs to no avail, and be anti–double-stranded DNA (anti-dsDNA) antibody positive. Dr. Alexander reported that the median baseline SLEDAI-2K score was 12 and ranged from 8 to 20, with the number of prior therapies ranging from two to nine.
Daratumumab was given at a dose of 1800 mg via subcutaneous injection every week for 8 weeks. This is the same dose that is used to treat multiple myeloma, Dr. Alexander explained, although the dosing is not stopped. The reason for stopping after 8 weeks in the current trial was to be able to see what happened once the treatment was stopped. The follow-up was for 36 weeks.
Dr. Alexander reported that there was a “very dramatic and significant” effect on the primary endpoint of a reduction in anti-dsDNA antibody levels, decreasing from a median of 166.3 U/mL at baseline to 61.1 U/mL at week 12 (P = .002). Alongside, there was a reduction in the SLEDAI-2K score from 12 to 4 within 12 weeks, which was sustained at the 36-week follow-up assessment. Improvements in skin, joint, kidney, and level of proteinuria were also seen.
Although all patients experienced adverse events, none were serious. Infections and infestations (mostly nasopharyngitis, COVID-19, and gastroenteritis) were the most common, experienced by 80% of the participants; 70% had injection site reactions or fatigue, 60% had gastrointestinal symptoms, 50% had a fall of IgG < 5 g/L, 40% had headache, and 20% had back pain.
“This is a positive trial. I think we could demonstrate that [daratumumab] produced very strong, rapid, and durable clinical improvements,” Dr. Alexander said. “We think that targeting CD38 is relevant; plasma cells had been depleted based on the reduction of anti-dsDNA antibodies,” he added.
From the audience, however, Peter Nash, MBBS, of Griffith University in Brisbane, Australia, questioned whether the results could be attributed to “a steroid effect” because patients had been treated with oral dexamethasone throughout the study.
Dr. Alexander noted that steroid use had been part of the treatment schedule but acknowledged it was a possible confounder.
“I think we can be confident that [daratumumab] had a major effect on plasma cells decreasing…because we see that also the vaccine titers decreased,” Dr. Alexander said. “Time will tell, but even more important is the durability of the responses over time, which you don’t achieve under steroids.”
KPG-818’s Novel Mechanism of Action
Elsewhere at EULAR 2024, positive results of another phase 2 study involving a drug with an entirely different mechanism of action, KPG-818, were reported in a poster presentation. KPG-818 modulates CRBN, which results in the degradation of two transcription factors (Aiolos and Ikaros) that are involved in the development, maturation, and proliferation of innate and adaptive immune cells and have been linked to genetic risk in SLE, according to the poster’s authors. It is currently in development for the treatment of SLE, Behçet disease, inflammatory bowel disease, multiple myeloma, and non-Hodgkin lymphoma.
Yao Wang, MD, chief medical officer of KPG-818’s developer Kangpu Biopharmaceuticals, Hefei, China, and associates found that oral doses of 0.15 or 0.6 mg KPG-818 were “generally well-tolerated” and produced immunomodulatory changes that could be beneficial in people with SLE over a 12-week treatment period.
“Only two new agents have been approved for the treatment of SLE in the past five decades in USA and Europe,” Dr. Wang and team wrote, which highlights “a significant unmet need for more effective and safe treatment options.”
They believe that KPG-818 might well fit the bill based on the results of their study, in which 35 of 37 recruited patients completed the treatment. Compared with placebo, they observed reduced numbers of total B cells, Aiolos+ T and B cells, and increased Treg cells.
SLEDAI-2K and Cutaneous Lupus Erythematosus Disease Area and Severity Index activity scores in the 0.15-mg group were improved relative to baseline and placebo.
“The proof-of-concept findings suggest a favorable benefit/risk ratio in SLE for KPG-818,” Dr. Wang and coauthors said, supporting its further development in SLE.
Need for Treatments
Dr. Isenberg told this news organization that both daratumumab and KPG-818 would be welcome additions as treatment options if further trials proved their worth.
“The great frustration about lupus is that, compared to patients with rheumatoid arthritis, the choice has been so limited,” Dr. Isenberg said. Aside from rituximab (Rituxan) and belimumab (Benlysta), which are used with certain restrictions, there are no other biologic targeted treatments available in the United Kingdom. Anifrolumab (Saphnelo) has a license in the United States and some European countries but is not yet available for him to use in his practice.
Daratumumab and KPG-818 are “different types of molecules, and if they work that will be great. It would be nice to have the choice,” Dr. Isenberg said. “Whether they will be as effective as I think rituximab is, I don’t know, but these are some very encouraging results.”

These drugs were found to work and be generally safe in phase 1 and 2 trials, but “when they come to phase 3, they all seem to fail, and we don’t know why.”
These are large global studies, D’Cruz added, observing that problems with patient selection, steroid use, and choice of outcome measures were possible factors for why the EXPLORER and LUNAR studies had shown no benefit for rituximab despite the drug being widely used to treat SLE.
Dr. Isenberg, who has coauthored an article on the topic of why drugs seem to fail at the final hurdle, noted: “I think it has a lot to do with the nature of the disease. It’s a complicated disease.” From having “savvy physicians doing the trials for you” to the placebo response, there are “a whole bunch or reasons why these things haven’t worked in lupus.”
Dr. Morand commented: “We’ve got many programs in phase 2 and 3, and because there’s so many, they’re all facing recruitment challenges, and as a consequence of so much activity, every program is going a little slower than hoped for.”
As for other drugs on the horizon, Dr. Morand noted: “We’re very optimistic about things like litifilimab and deucravacitinib; that’s two examples that are in phase 3. Earlier in the program of development, [there are] a huge range of targets being addressed. The future looks bright. But we might have to wait a while.”

FROM EULAR 2024
Trends in Rheumatic Disease Pain Management Show Decline in Opioid Use
TOPLINE:
Since 2014, opioid use for autoimmune rheumatic diseases decreased by 15% annually while other management modalities increased or stabilized.
METHODOLOGY:
- Researchers analyzed de-identified US claims data from the MarketScan Database from 2007-2021.
- The study included nearly 142,000 patients with autoimmune rheumatic diseases: 10,927 with ankylosing spondylitis (AS); 21,438 with psoriatic arthritis (PsA); 71,393 with rheumatoid arthritis (RA); 16,718 with Sjögren disease; 18,018 with systemic lupus erythematosus; and 3468 with systemic sclerosis.
- Primary outcome was opioid use annual trends, with secondary outcomes including trends in the use of anticonvulsants, antidepressants, skeletal muscle relaxants, nonsteroidal anti-inflammatory drugs (NSAIDs), topical pain medications, and physical or occupational therapy.
TAKEAWAY:
- The incidence of opioid use increased annually by 4% until 2014 and decreased annually by 15% after 2014.
- NSAID use increased 2% annually until 2014, then declined by 5% afterward.
- The proportion of patients utilizing physical therapy or anticonvulsants doubled from 2008 to 2020.
- NSAID prescriptions were highest in AS, PsA, and RA, while they were lowest in Sjögren disease and systemic sclerosis.
IN PRACTICE:
“Our work, along with the published literature, highlights the need for future studies to evaluate the effectiveness of pain management modality changes over time and to understand the possible effects that changes have had on outcomes such as quality of life, disability, health status, and function,” wrote the authors of the study.
SOURCE:
The study was led by Titilola Falasinnu, PhD, Stanford University School of Medicine, Stanford, California. It was published online in The Lancet Rheumatology.
LIMITATIONS:
The study relied on administrative claims data, which did not contain information on use of over-the-counter medications like NSAIDs and topical analgesics. The study did not include the duration of pain treatment modalities, making it difficult to differentiate between acute and chronic use. The analysis did not include race or ethnicity, which is important for understanding pain outcomes across different sociodemographic groups.
DISCLOSURES:
The study was supported by grants from the National Institute of Arthritis and Musculoskeletal and Skin Diseases.

Advantages of a Pediatric Rheumatology/Dermatology Clinic Evaluated
“This finding highlights the complexity of patients referred to this clinic,” the study’s first author, Jessica Crockett, a fourth-year medical student at UCSF, told this news organization following the annual meeting of the Society for Pediatric Dermatology, where the study was presented during a poster session. “Integrated care models such as rheumatology/dermatology clinics (RDCs) have been shown to facilitate complete clinical evaluations, establish new or revised diagnoses, and streamline care for adult patients with complex autoimmune skin diseases. However, few pediatric RDCs exist nationwide, and data therefore is quite limited.”
To advance the understanding of pediatric RDC practice patterns, the influence of the care model on patient care, and professional development for trainees and clinicians, Ms. Crockett collaborated with senior author Kelly Cordoro, MD, professor of dermatology and pediatrics at UCSF, and colleagues to evaluate a cohort of 71 patients who received care at the UCSF pediatric RDC. The clinic, which was launched in 2017, includes two dermatologists, two rheumatologists, trainees, a social worker, and a nurse. Team members participate in a preclinic conference to review patient data and images, discuss relevant literature, and develop an approach to each patient.
In a separate part of the study, the researchers distributed a survey to 17 pediatric dermatologists who participate in unique RDCs in North America. Respondents were asked to describe the variability of clinical operations, participants, administrative/clinical support, and educational value for participating physicians and trainees.
Of the 71 patients cared for at the UCSF pediatric RDC, 69% were female, 44% were White, 51% were aged 13-21 years, 42% were aged 3-12 years, and 7% were aged 0-11 years at their first clinic visit. The top four primary RDC diagnoses were linear morphea (33%), lupus (23%), psoriasis (13%), and juvenile dermatomyositis (10%).
Nearly one in four patients (17, or 24%) presented to the RDC without a confirmed diagnosis. A diagnosis was established at the first RDC visit for 7 of these 17 patients (41%). Among 54 patients who presented with an established diagnosis, the first RDC visit confirmed the diagnosis for 52 (96%) and revised it for 2 (4%). “Initial pediatric RDC evaluation significantly influenced patient care by confirming or revising preexisting diagnoses, rendering new diagnoses, and streamlining additional laboratory and imaging recommendations,” the researchers wrote in their poster.
The evaluation also resulted in modified disease management in the form of systemic medication changes or dosage adjustments as well as the initiation of novel therapies. For example, systemic medication changes were made during the first RDC visit in 34 of the 46 patients (74%) who were on systemic medication at presentation.
“Seeing complex patients together in real time allows specialists and other team members (social work, nursing, PT/OT, for example) to share ideas, communicate clearly to families, and efficiently develop recommendations,” Ms. Crockett said of the UCSF pediatric RDC. “Exposure to other specialists while caring for patients enhances medical knowledge, communication skills, and professional competency of faculty and trainees alike.”
In the survey portion of the study, each of the 17 dermatologists reported that the pediatric RDC is valuable for patient care, and 88% believed the RDC was a valuable use of their time. However, only 59% of respondents reported having administrative support, and only 29% had a dedicated clinic coordinator or navigator.
“We were surprised to find that only a quarter of pediatric RDCs incorporate an educational conference,” Dr. Cordoro told this news organization. “We have found that assembling the care team prior to seeing patients to review clinical data, discuss relevant literature, and define the clinical questions for each patient is an integral part of the clinical operation. The trainees are involved in these conference presentations, and it really enhances their understanding of the complex diagnoses we manage in this clinic and the issues faced by affected children and families. The preclinical conference increases efficiency, positively influences patient care, and supports professional development for all participants.”
The study was indirectly supported by a fellowship grant awarded to Ms. Crockett from the Pediatric Dermatology Research Alliance. The researchers reported having no relevant disclosures.

“This finding highlights the complexity of patients referred to this clinic,” the study’s first author, Jessica Crockett, a fourth-year medical student at UCSF, told this news organization following the annual meeting of the Society for Pediatric Dermatology, where the study was presented during a poster session. “Integrated care models such as rheumatology/dermatology clinics (RDCs) have been shown to facilitate complete clinical evaluations, establish new or revised diagnoses, and streamline care for adult patients with complex autoimmune skin diseases. However, few pediatric RDCs exist nationwide, and data therefore is quite limited.”
To advance the understanding of pediatric RDC practice patterns, the influence of the care model on patient care, and professional development for trainees and clinicians, Ms. Crockett collaborated with senior author Kelly Cordoro, MD, professor of dermatology and pediatrics at UCSF, and colleagues to evaluate a cohort of 71 patients who received care at the UCSF pediatric RDC. The clinic, which was launched in 2017, includes two dermatologists, two rheumatologists, trainees, a social worker, and a nurse. Team members participate in a preclinic conference to review patient data and images, discuss relevant literature, and develop an approach to each patient.
In a separate part of the study, the researchers distributed a survey to 17 pediatric dermatologists who participate in unique RDCs in North America. Respondents were asked to describe the variability of clinical operations, participants, administrative/clinical support, and educational value for participating physicians and trainees.
Of the 71 patients cared for at the UCSF pediatric RDC, 69% were female, 44% were White, 51% were aged 13-21 years, 42% were aged 3-12 years, and 7% were aged 0-11 years at their first clinic visit. The top four primary RDC diagnoses were linear morphea (33%), lupus (23%), psoriasis (13%), and juvenile dermatomyositis (10%).
Nearly one in four patients (17, or 24%) presented to the RDC without a confirmed diagnosis. A diagnosis was established at the first RDC visit for 7 of these 17 patients (41%). Among 54 patients who presented with an established diagnosis, the first RDC visit confirmed the diagnosis for 52 (96%) and revised it for 2 (4%). “Initial pediatric RDC evaluation significantly influenced patient care by confirming or revising preexisting diagnoses, rendering new diagnoses, and streamlining additional laboratory and imaging recommendations,” the researchers wrote in their poster.
The evaluation also resulted in modified disease management in the form of systemic medication changes or dosage adjustments as well as the initiation of novel therapies. For example, systemic medication changes were made during the first RDC visit in 34 of the 46 patients (74%) who were on systemic medication at presentation.

Steroids’ 75th Anniversary: Clinicians Strive to Use Less
Now, 75 years after the first presentations were made on the “sensational” effects of cortisone in the treatment of rheumatoid arthritis (RA), glucocorticoids (GCs) are still highly relevant and widely used in the management of RA and other immune-mediated inflammatory diseases.
“It makes me smile because this is such an old drug, and we need it still so much. It still hasn’t been replaced,” Josef S. Smolen, MD, observed at annual European Congress of Rheumatology.
At low doses, GCs are highly effective as anti-inflammatory and anti-destructive agents in RA and many other diseases, said Dr. Smolen, a rheumatologist and immunologist and professor emeritus at the Medical University of Vienna, Austria.
But even after all this time, the mechanisms that lead to efficacy vs toxicity have yet to be clarified. “Such separation may provide further insights into future treatment options,” said Dr. Smolen.
His comments, made during a special session on the 75th anniversary of GCs at EULAR 2024, underscore the endless saga to manage GCs while finding better alternatives. Opinions differ on what the research says on toxicity and dosage and whether a long-term, low-dose option is viable. Alternative therapies are being studied, but those endeavors are still in the early stages of development.
While GCs are still used chronically in many patients, clinicians should always attempt to discontinue them whenever possible, Frank Buttgereit, MD, professor of rheumatology and deputy head of the Department of Rheumatology and Clinical Immunology at Charité – Universitätsmedizin Berlin, Germany, told attendees at the congress. Up to 60% of patients in registries use GCs, and many patients with early or established RA enter randomized controlled trials on GCs as maintenance therapy.
The ubiquity of GC usage stems in part from overprescribing by non-rheumatologist physicians who might not have access to or aren’t aware of newer biologics or disease-modifying antirheumatic drugs (DMARDs). “We see a lot of patients on long-term glucocorticoids, chronic use for years and years, decades of glucocorticoids,” said Giovanni Adami, MD, PhD, a rheumatologist at the University of Verona, Italy, who has coauthored several studies on the use of GCs.
Societies Agree: Discontinue as Fast as Possible
GCs have been associated with a long list of adverse events, most notably Cushing syndrome, hypertension, cardiovascular disease, osteoporosis, myopathy, peptic ulcer, adrenal insufficiency (AI), infections, mood disorders, ophthalmologic disorders such as cataracts, skin disorders, menstrual septic necrosis, and pancreatitis.
Dose matters, Dr. Smolen said, citing studies that found that cumulative GC doses of 1000 or 1100 mg increase risks. One study by German researchers found that doses above 10 mg/d significantly raised the hazard ratio for death.
Because high disease activity is also associated with an equally high mortality risk, “we have to balance this out: Active disease vs glucocorticoid use, especially in countries that have less access to modern therapies than we have in the more affluent Western regions,” Dr. Smolen said.
Rheumatology societies generally agree that clinicians should try to minimize GC use or eventually discontinue the therapy.
The American College of Rheumatology recommends not using GCs as part of the first-line treatment of RA. “And if you want to use [them], you should do that for less than 3 months, taper and discontinue as fast as possible, and use the lowest dose possible,” Dr. Adami said.
EULAR’s recommendation is more nuanced in that it allows for a lower dose but gives physicians more choice in how they want to handle GCs, Dr. Adami said. The task force added that all patients should try to taper down or discontinue as fast as possible, he said.
For GCs in the management of systemic lupus erythematosus, a EULAR task force recommended that the type and severity of organ involvement should determine dose, with a long-term goal of maintaining the dose < 5 mg/d or possibly withdrawing it.
EULAR also recommends GC bridging when initiating or changing conventional synthetic (cs) DMARDs. This effectively dismisses the use of GCs when using biologic DMARDs or targeted synthetic DMARDs. As a bridging therapy, EULAR recommends either a single parenteral dose of GC or a predefined tapering or discontinuation scheme within 3 months, when starting an oral GC.
Low-Dose Approach Gains Ground
While saying he’d be the first physician to eliminate GCs whenever possible, Dr. Buttgereit made the case before the EULAR Congress that GCs in low doses could still play a role in treatment.
Many physicians believe that very low doses between 2 and 4 mg/d are a realistic therapy option for RA, he said, adding that a mean daily usage < 5 mg could be used over a longer period with relatively low risk.
Several studies he coauthored tested the 5-mg approach. The GLORIA trial compared 5 mg/d prednisolone and placebo in 451 patients aged 65 years and older with active RA over the course of 2 years. The researchers found that patients on prednisolone had a mean Disease Activity Score in 28 joints (DAS28) that was 0.37 points lower and mean joint damage score that was 1.7 points lower than those of patients on placebo, suggesting that the GC had long-term benefits in these patients with RA.
The tradeoff was a 24% increase in the risk of having at least one adverse event of special interest, but most of these events were non-severe infections, Dr. Buttgereit said.
Another study, the SEMIRA trial, assigned 128 patients to a continued regimen of prednisone 5 mg/d for 24 weeks. Another group of 131 patients received a tapered-prednisone regimen. All patients received tocilizumab 162 mg with or without csDMARDs, maintained at stable doses.
Patients in the first cohort achieved superior disease activity control than those in the tapered regimen group. “The side effects showed that in the tapering prednisone group, there were more treatment-emergent adverse effects in this double-blind trial as compared to the continued prednisone group,” Dr. Buttgereit said.
One limitation of the SEMIRA trial was that it studied the effect of tocilizumab as a GC-sparing agent, and it didn’t consider using a tumor necrosis factor or Janus kinase (JAK) inhibitor, which might have a more potent effect on pain and GC dose reduction, Dr. Adami said. “Why do we need to use glucocorticoids if we know they might be detrimental, if we know there might be some other option in our armamentarium?”
Other studies have shown that low-dose GC protocols can be used with standard treatment, according to Sebastian E. Sattui, MD, assistant professor of medicine and director of the Vasculitis Center at the University of Pittsburgh School of Medicine.
“Examples of this are the LoVAS and PEXIVAS studies for antineutrophil cytoplasmic antibody-associated [ANCA] vasculitis. This has been highlighted in existing treatment recommendations for ANCA vasculitis and systemic lupus erythematosus nephritis,” Dr. Sattui said.
Two-year results from LoVAS showed noninferiority in remission induction rates and rates of relapse and significantly less frequent serious adverse events between a reduced-dose GC regimen at 0.5 mg/kg/d and conventional high-dose GC regimen at 1 mg/kg/d plus rituximab for ANCA vasculitis.
PEXIVAS demonstrated the noninferiority of a reduced-dose regimen of GCs vs a standard-dose regimen with respect to death or end-stage kidney disease in patients with severe disease involvement.
Debating the Toxicity Threshold
Are low GC dosages significantly associated with adverse events like mortality, cardiovascular, or diabetes risk? It depends on who you ask.
Much of the toxicity data on GCs come from inadequately powered or controlled studies and often refer to doses that currently are considered too high, Dr. Buttgereit said. His presentation highlighted a study from Hong Kong, a time-varying analysis of GC dose and incident risk for major adverse cardiovascular events (MACE) in more than 12,000 patients with RA. Researchers found that GC regimens ≥ 5 mg/d significantly increased the risk for MACE. Comparatively, doses below this threshold did not confer excessive risk, he said.
Low-dose GCs are lesser toxic than high-dose GCs, noted Joan Merrill, MD, a professor with the Arthritis and Clinical Immunology Research Program at The University of Oklahoma Health Sciences Center, Oklahoma City. “There may be less weight gain, less chance of acne, and less risk for all the slower, more organ-threatening side effects.”
Dr. Merrill, who cares for patients with lupus, said physicians can keep lupus in check for years, using constant, low-dose GCs. “The one thing we know is that steroids work.” But over many years, damage may still occur, she cautioned.
But even a low dose could present health problems to patients. The GLORIA trial of patients with RA, which showed promising results on disease control with 5 mg/d, found an association between GCs and increased risk for infection and osteoporosis. There was a higher overall risk for adverse events related to skin, infections, and bone mineral density changes. Bone mineral density loss and fractures were more common in the GC group, Adami noted.
Surprisingly, some of the trial’s authors said patients could handle such adverse events. But what is your threshold of “acceptable?” Dr. Adami asked.
Other studies have found associations between low-dose GC regimens and adverse events. Researchers of a 2023 study reported bone mineral density loss in patients with inflammatory rheumatic musculoskeletal diseases on a 2.5-mg/d regimen. Another decade-long analysis of Medicare and Optum data found a link between serious infection and low-dose GCs in patients receiving stable DMARD therapy. Investigators reported risk even at daily doses of ≤ 5 mg.
Dr. Adami acknowledged that these studies may have “confounding by indication,” a channeling bias in which people with severe RA are more likely to be treated with GCs. For this reason, it’s a challenge to disentangle the independent role of GCs from the disease activity itself, he said.
The big question is: Why don’t these observational studies show an increased risk for adverse events with biologic drugs that are given to more severe patients? “That confirms the hypothesis that confounding by indication for GCs is minimal, and most of the risk is driven by GCs,” he said.
Tapering Options Across Diseases
Rheumatologists in the field continue to navigate GC-tapering options and treatment combinations that reduce the cumulative use of GCs over time, finding their own solutions based on the conditions they treat.
In his EULAR presentation, Dr. Buttgereit suggested that current therapeutic approaches for RA may be too narrow when they don’t consider the possibility of including very low doses of GCs.
For RA, “why shouldn’t we not do a combination of something like methotrexate plus a JAK inhibitor or a biological,” plus a very low dose of GCs < 5 mg/d, he asked.
However, Dr. Adami said he generally avoids GCs if RA disease activity is not severe (based on DAS28) and if the patient has a visual analog scale pain score < 7. “Nonetheless, even in patients with more severe disease, I would avoid GCs for more than 3 months. Usually, 1 month of steroids, tapered rapidly and discontinued.”
All patients should receive an appropriate treat-to-target strategy with csDMARDs and biologics if needed, he added.
A patient coming to clinic with difficult-to-treat RA who chronically uses GCs deserves special attention. The priority is bone protection with an anti-osteoporosis medication. “I found that JAK inhibitors, in some cases, help with the discontinuation of steroids, especially in those with residual pain. Therefore, I would think of switching medication,” Dr. Adami said.
For polymyalgia rheumatica, most clinicians will likely try to taper GCs around 52 weeks, similar to ACR/EULAR guidelines, according to Robert F. Spiera, MD, director of the Scleroderma and Vasculitis Program at Hospital for Special Surgery, New York City.
“I usually challenge patients with a more rapid taper, hoping to get them off GCs in 6 or even 4 months in some patients, recognizing that many will flare, and we will have to bump up their GC dose,” Dr. Spiera said.
For patients with lupus, GCs remain the most effective treatment, Dr. Merrill said. “The toxicities are unacceptable for long-term use. So we try to get in fast when we need them and get out as soon as possible after that, tapering down as fast as the patient can tolerate it.”
Unfortunately, that’s not always as fast as the clinician or patient hopes for, she said.
“New treatments are being developed that may help us avoid the constant use of steroids. However, it would be wonderful to see how these new safer types of steroids work in lupus,” she said.
Minimizing GCs is an important goal that should be considered and aimed for in every single patient, Dr. Sattui said. “Risk of GC toxicity should be considered in all patients, assessing [them] for cardiometabolic comorbidities, bone metabolic diseases, risk of infection, among many others.” Sticking to one specific GC-tapering protocol might not be achievable for every patient, however, based on disease characteristics, response, and other factors, he added.
Monitoring for GC toxicity is important and should occur during and after every single clinical visit, he emphasized. Patient education is critical. “Different tools have been developed and employed in clinical trials, both patient- and physician-facing instruments. Implementation to clinical practice of some of these should be the next step in order to achieve a more systematic approach.”
What to Consider for AI Symptoms
Clinicians also need to address AI in patients who are coming off GCs, Dr. Sattui said. He advised that symptoms suggestive of AI, including malaise, fatigue, nausea, and muscle and/or joint pain, should guide testing.
Even in the absence of symptoms, clinicians should consider assessing patients who have been on high doses for prolonged periods or obese or older adults who might be at a high risk for AI. “Signs to consider include weight loss, hypotension, or orthostatism,” he said.
Differentiating between AI symptoms and symptoms from the underlying disease can be a challenge. This requires a physical exam and workup, including morning serum cortisol. Collaboration with endocrinology colleagues and other treating providers is important, as well as patient education of symptoms and monitoring for possible adjustments in treating AI and other acute diseases, he said.
Dr. Smolen received research grants from AbbVie, AstraZeneca, Galapagos, and Eli Lilly. Dr. Adami received speaker fees and/or was a consultant for Galapagos, Theramex, Amgen, Eli Lilly, UCB, Fresenius Kabi, Bristol Myers Squibb, Abiogen, and Pfizer. Dr. Buttgereit’s disclosures included AbbVie, AstraZeneca, Grünenthal, Horizon Therapeutics, Mundipharma, Pfizer, and Roche. Dr. Merrill had no relevant disclosures. Dr. Spiera has been a consultant for Roche-Genentech, GlaxoSmithKline, Sanofi, ChemoCentryx, Novartis, Galderma, Cytori, AstraZeneca, Amgen, and AbbVie and received research grant support from GlaxoSmithKline, Roche-Genentech, AstraZeneca, Bristol Myers Squibb, Kadmon, Boehringer Ingelheim, Cytori, ChemoCentryx, Corbus, Novartis, Amgen, and AbbVie. Dr. Sattui reported receiving research support from AstraZeneca and GlaxoSmithKline (clinical trials), receiving consulting fees from Sanofi (funds toward research support), serving on advisory boards for Sanofi and Amgen (funds toward research support), and receiving speaker fees from Fresenius Kabi (funds toward research support).

Rheumatologists in the field continue to navigate GC-tapering options and treatment combinations that reduce the cumulative use of GCs over time, finding their own solutions based on the conditions they treat.
In his EULAR presentation, Dr. Buttgereit suggested that current therapeutic approaches for RA may be too narrow when they don’t consider the possibility of including very low doses of GCs.
For RA, “why shouldn’t we not do a combination of something like methotrexate plus a JAK inhibitor or a biological,” plus a very low dose of GCs < 5 mg/d, he asked.
However, Dr. Adami said he generally avoids GCs if RA disease activity is not severe (based on DAS28) and if the patient has a visual analog scale pain score < 7. “Nonetheless, even in patients with more severe disease, I would avoid GCs for more than 3 months. Usually, 1 month of steroids, tapered rapidly and discontinued.”
All patients should receive an appropriate treat-to-target strategy with csDMARDs and biologics if needed, he added.
A patient coming to clinic with difficult-to-treat RA who chronically uses GCs deserves special attention. The priority is bone protection with an anti-osteoporosis medication. “I found that JAK inhibitors, in some cases, help with the discontinuation of steroids, especially in those with residual pain. Therefore, I would think of switching medication,” Dr. Adami said.
For polymyalgia rheumatica, most clinicians will likely try to taper GCs around 52 weeks, similar to ACR/EULAR guidelines, according to Robert F. Spiera, MD, director of the Scleroderma and Vasculitis Program at Hospital for Special Surgery, New York City.
“I usually challenge patients with a more rapid taper, hoping to get them off GCs in 6 or even 4 months in some patients, recognizing that many will flare, and we will have to bump up their GC dose,” Dr. Spiera said.
For patients with lupus, GCs remain the most effective treatment, Dr. Merrill said. “The toxicities are unacceptable for long-term use. So we try to get in fast when we need them and get out as soon as possible after that, tapering down as fast as the patient can tolerate it.”
Unfortunately, that’s not always as fast as the clinician or patient hopes for, she said.
“New treatments are being developed that may help us avoid the constant use of steroids. However, it would be wonderful to see how these new safer types of steroids work in lupus,” she said.
Minimizing GCs is an important goal that should be considered and aimed for in every single patient, Dr. Sattui said. “Risk of GC toxicity should be considered in all patients, assessing [them] for cardiometabolic comorbidities, bone metabolic diseases, risk of infection, among many others.” Sticking to one specific GC-tapering protocol might not be achievable for every patient, however, based on disease characteristics, response, and other factors, he added.
Monitoring for GC toxicity is important and should occur during and after every single clinical visit, he emphasized. Patient education is critical. “Different tools have been developed and employed in clinical trials, both patient- and physician-facing instruments. Implementation to clinical practice of some of these should be the next step in order to achieve a more systematic approach.”
What to Consider for AI Symptoms
Clinicians also need to address AI in patients who are coming off GCs, Dr. Sattui said. He advised that symptoms suggestive of AI, including malaise, fatigue, nausea, and muscle and/or joint pain, should guide testing.
Even in the absence of symptoms, clinicians should consider assessing patients who have been on high doses for prolonged periods or obese or older adults who might be at a high risk for AI. “Signs to consider include weight loss, hypotension, or orthostatism,” he said.
Differentiating between AI symptoms and symptoms from the underlying disease can be a challenge. This requires a physical exam and workup, including morning serum cortisol. Collaboration with endocrinology colleagues and other treating providers is important, as well as patient education of symptoms and monitoring for possible adjustments in treating AI and other acute diseases, he said.

Now, 75 years after the first presentations were made on the “sensational” effects of cortisone in the treatment of rheumatoid arthritis (RA), glucocorticoids (GCs) are still highly relevant and widely used in the management of RA and other immune-mediated inflammatory diseases.
“It makes me smile because this is such an old drug, and we need it still so much. It still hasn’t been replaced,” Josef S. Smolen, MD, observed at annual European Congress of Rheumatology.
At low doses, GCs are highly effective as anti-inflammatory and anti-destructive agents in RA and many other diseases, said Dr. Smolen, a rheumatologist and immunologist and professor emeritus at the Medical University of Vienna, Austria.
But even after all this time, the mechanisms that lead to efficacy vs toxicity have yet to be clarified. “Such separation may provide further insights into future treatment options,” said Dr. Smolen.
His comments, made during a special session on the 75th anniversary of GCs at EULAR 2024, underscore the endless saga to manage GCs while finding better alternatives. Opinions differ on what the research says on toxicity and dosage and whether a long-term, low-dose option is viable. Alternative therapies are being studied, but those endeavors are still in the early stages of development.
While GCs are still used chronically in many patients, clinicians should always attempt to discontinue them whenever possible, Frank Buttgereit, MD, professor of rheumatology and deputy head of the Department of Rheumatology and Clinical Immunology at Charité – Universitätsmedizin Berlin, Germany, told attendees at the congress. Up to 60% of patients in registries use GCs, and many patients with early or established RA enter randomized controlled trials on GCs as maintenance therapy.
The ubiquity of GC usage stems in part from overprescribing by non-rheumatologist physicians who might not have access to or aren’t aware of newer biologics or disease-modifying antirheumatic drugs (DMARDs). “We see a lot of patients on long-term glucocorticoids, chronic use for years and years, decades of glucocorticoids,” said Giovanni Adami, MD, PhD, a rheumatologist at the University of Verona, Italy, who has coauthored several studies on the use of GCs.
Societies Agree: Discontinue as Fast as Possible
GCs have been associated with a long list of adverse events, most notably Cushing syndrome, hypertension, cardiovascular disease, osteoporosis, myopathy, peptic ulcer, adrenal insufficiency (AI), infections, mood disorders, ophthalmologic disorders such as cataracts, skin disorders, menstrual septic necrosis, and pancreatitis.
Dose matters, Dr. Smolen said, citing studies that found that cumulative GC doses of 1000 or 1100 mg increase risks. One study by German researchers found that doses above 10 mg/d significantly raised the hazard ratio for death.
Because high disease activity is also associated with an equally high mortality risk, “we have to balance this out: Active disease vs glucocorticoid use, especially in countries that have less access to modern therapies than we have in the more affluent Western regions,” Dr. Smolen said.
Rheumatology societies generally agree that clinicians should try to minimize GC use or eventually discontinue the therapy.
The American College of Rheumatology recommends not using GCs as part of the first-line treatment of RA. “And if you want to use [them], you should do that for less than 3 months, taper and discontinue as fast as possible, and use the lowest dose possible,” Dr. Adami said.
EULAR’s recommendation is more nuanced in that it allows for a lower dose but gives physicians more choice in how they want to handle GCs, Dr. Adami said. The task force added that all patients should try to taper down or discontinue as fast as possible, he said.
For GCs in the management of systemic lupus erythematosus, a EULAR task force recommended that the type and severity of organ involvement should determine dose, with a long-term goal of maintaining the dose < 5 mg/d or possibly withdrawing it.
EULAR also recommends GC bridging when initiating or changing conventional synthetic (cs) DMARDs. This effectively dismisses the use of GCs when using biologic DMARDs or targeted synthetic DMARDs. As a bridging therapy, EULAR recommends either a single parenteral dose of GC or a predefined tapering or discontinuation scheme within 3 months, when starting an oral GC.
Low-Dose Approach Gains Ground
While saying he’d be the first physician to eliminate GCs whenever possible, Dr. Buttgereit made the case before the EULAR Congress that GCs in low doses could still play a role in treatment.
Many physicians believe that very low doses between 2 and 4 mg/d are a realistic therapy option for RA, he said, adding that a mean daily usage < 5 mg could be used over a longer period with relatively low risk.
Several studies he coauthored tested the 5-mg approach. The GLORIA trial compared 5 mg/d prednisolone and placebo in 451 patients aged 65 years and older with active RA over the course of 2 years. The researchers found that patients on prednisolone had a mean Disease Activity Score in 28 joints (DAS28) that was 0.37 points lower and mean joint damage score that was 1.7 points lower than those of patients on placebo, suggesting that the GC had long-term benefits in these patients with RA.
The tradeoff was a 24% increase in the risk of having at least one adverse event of special interest, but most of these events were non-severe infections, Dr. Buttgereit said.
Another study, the SEMIRA trial, assigned 128 patients to a continued regimen of prednisone 5 mg/d for 24 weeks. Another group of 131 patients received a tapered-prednisone regimen. All patients received tocilizumab 162 mg with or without csDMARDs, maintained at stable doses.
Patients in the first cohort achieved superior disease activity control than those in the tapered regimen group. “The side effects showed that in the tapering prednisone group, there were more treatment-emergent adverse effects in this double-blind trial as compared to the continued prednisone group,” Dr. Buttgereit said.
One limitation of the SEMIRA trial was that it studied the effect of tocilizumab as a GC-sparing agent, and it didn’t consider using a tumor necrosis factor or Janus kinase (JAK) inhibitor, which might have a more potent effect on pain and GC dose reduction, Dr. Adami said. “Why do we need to use glucocorticoids if we know they might be detrimental, if we know there might be some other option in our armamentarium?”
Other studies have shown that low-dose GC protocols can be used with standard treatment, according to Sebastian E. Sattui, MD, assistant professor of medicine and director of the Vasculitis Center at the University of Pittsburgh School of Medicine.
“Examples of this are the LoVAS and PEXIVAS studies for antineutrophil cytoplasmic antibody-associated [ANCA] vasculitis. This has been highlighted in existing treatment recommendations for ANCA vasculitis and systemic lupus erythematosus nephritis,” Dr. Sattui said.
Two-year results from LoVAS showed noninferiority in remission induction rates and rates of relapse and significantly less frequent serious adverse events between a reduced-dose GC regimen at 0.5 mg/kg/d and conventional high-dose GC regimen at 1 mg/kg/d plus rituximab for ANCA vasculitis.
PEXIVAS demonstrated the noninferiority of a reduced-dose regimen of GCs vs a standard-dose regimen with respect to death or end-stage kidney disease in patients with severe disease involvement.
Debating the Toxicity Threshold
Are low GC dosages significantly associated with adverse events like mortality, cardiovascular, or diabetes risk? It depends on who you ask.
Much of the toxicity data on GCs come from inadequately powered or controlled studies and often refer to doses that currently are considered too high, Dr. Buttgereit said. His presentation highlighted a study from Hong Kong, a time-varying analysis of GC dose and incident risk for major adverse cardiovascular events (MACE) in more than 12,000 patients with RA. Researchers found that GC regimens ≥ 5 mg/d significantly increased the risk for MACE. Comparatively, doses below this threshold did not confer excessive risk, he said.
Low-dose GCs are lesser toxic than high-dose GCs, noted Joan Merrill, MD, a professor with the Arthritis and Clinical Immunology Research Program at The University of Oklahoma Health Sciences Center, Oklahoma City. “There may be less weight gain, less chance of acne, and less risk for all the slower, more organ-threatening side effects.”
Dr. Merrill, who cares for patients with lupus, said physicians can keep lupus in check for years, using constant, low-dose GCs. “The one thing we know is that steroids work.” But over many years, damage may still occur, she cautioned.
But even a low dose could present health problems to patients. The GLORIA trial of patients with RA, which showed promising results on disease control with 5 mg/d, found an association between GCs and increased risk for infection and osteoporosis. There was a higher overall risk for adverse events related to skin, infections, and bone mineral density changes. Bone mineral density loss and fractures were more common in the GC group, Adami noted.
Surprisingly, some of the trial’s authors said patients could handle such adverse events. But what is your threshold of “acceptable?” Dr. Adami asked.
Other studies have found associations between low-dose GC regimens and adverse events. Researchers of a 2023 study reported bone mineral density loss in patients with inflammatory rheumatic musculoskeletal diseases on a 2.5-mg/d regimen. Another decade-long analysis of Medicare and Optum data found a link between serious infection and low-dose GCs in patients receiving stable DMARD therapy. Investigators reported risk even at daily doses of ≤ 5 mg.
Dr. Adami acknowledged that these studies may have “confounding by indication,” a channeling bias in which people with severe RA are more likely to be treated with GCs. For this reason, it’s a challenge to disentangle the independent role of GCs from the disease activity itself, he said.
The big question is: Why don’t these observational studies show an increased risk for adverse events with biologic drugs that are given to more severe patients? “That confirms the hypothesis that confounding by indication for GCs is minimal, and most of the risk is driven by GCs,” he said.

FROM EULAR 2024
New Drugs, Treatment Strategies Aim to Lessen Rheumatic Diseases’ Reliance on Steroids
. Selective GC receptor agonists and modulators and GC plus hydroxysteroid dehydrogenase inhibitor combination therapy are some of the approaches under consideration.
“There is growing observational data that confirms the GC-sparing effect seen in some of these clinical trials in real-world data,” said Sebastian E. Sattui, MD, assistant professor of medicine and director of the Vasculitis Center at the University of Pittsburgh Medical Center, Pittsburgh.
GC minimization is an important goal, “and the data emerging from these trials should be reassuring for rheumatology providers,” Dr. Sattui said.
HSD-1 Inhibitors Under Study
11ß-Hydroxysteroid dehydrogenase type 1 (11ß-HSD1) is a tissue-specific intracellular modulator of GC action that’s been trialed for a number of rheumatic conditions. “HSD-1 deficiency or inhibition has been consistently associated with reduced GC side effects in mouse and human,” wrote the authors of a study testing the coadministration of HSD-1 inhibitor SPI-62 (clofutriben) with prednisolone in patients with polymyalgia rheumatica (PMR) to measure its impact on efficacy and toxicity.
Lead study author David Katz, PhD, chief scientific officer at Sparrow Pharmaceuticals, presented results at the at the annual European Congress of Rheumatology.
GCs are often the first-line therapy with PMR. However, it’s very difficult for patients to stop taking GCs once they start taking them. The study included patients with PMR who were taking 10 mg/d prednisolone and didn’t require a dose increase. For the study, they continued prednisolone without dose reduction for 4 weeks, receiving either SPI-62 6 mg/d or a matching placebo for 2 weeks.
During SPI-62 treatment, researchers in sequential cohorts maintained daily prednisolone doses at 10 mg, adjusted to 15 mg or adjusted to 20 mg.
A 10-mg dose of prednisolone combined with 6 mg of SPI-62 demonstrated less efficacy compared with placebo but improved upon prednisolone toxicities such as bone formation and resorption biomarkers, lipidemia, and insulin resistance. Doubling the dose to 20 mg prednisolone combined with SPI-62 achieved similar efficacy and maintained improvement of prednisolone toxicity markers.
“In patients with PMR, when we double the dose of prednisolone during coadministration with a potent HSD-1 inhibitor, we are able to have similar stability of symptoms, physical function, and systemic inflammation. At the same time, we are able to show improvements on biomarkers of bone turnover and insulin resistance,” Dr. Katz informed the EULAR 2024 audience.
An ongoing phase 2 clinical trial is testing SPI-62 in patients with endogenous Cushing syndrome. “It’s a longer-term trial, so we’re able to see at least an individual patient’s more clinical outcomes such as reversal of Cushing’s-associated myopathy and the ability of patients to discontinue all of their antidiabetic medications and yet still have good glycemic control,” he said.
Another research team from the United Kingdom explored whether AZD4017, an inhibitor of human 11ß-HSD1, could mitigate GC effects. The researchers randomly assigned 32 healthy male volunteers to AZD4017 or placebo, along with prednisolone. They reported a worsening of hepatic insulin sensitivity in the placebo group but not in the AZD4017 group, and protective effects of AZD4017 on markers of lipid metabolism and bone turnover, as well as lowered nighttime blood pressure. The results signified that coadministration of AZD4017 with prednisolone in men could be a way to reduce GC side effects.
In a Japanese phase 1/2 study, 11ß-HSD1 inhibitor S-707106 proved useful as an insulin sensitizer and antisarcopenic and anti-obesity medication in 16 patients with Cushing syndrome and autonomous cortisol secretion.
Novel Antitumor Necrosis Factor (TNF) Antibody Plus GC Receptor Modulator Conjugate
A novel antibody-drug conjugate comprising the anti-TNF monoclonal antibody adalimumab (ABBV-3373) linked to a GC receptor modulator shows promise as a GC alternative.
A notable 2022 study authored by Frank Buttgereit, MD, and other researchers assessed its safety and efficacy in a randomized, double-blind, active-controlled, proof-of-concept trial.
ABBV-3373 “was designed to potentially allow precise targeting of activated immune cells while significantly dampening inflammation and minimizing the systemic side effects associated with glucocorticoids,” according to AbbVie, its manufacturer.
A total of 48 adults with moderate to severe rheumatoid arthritis receiving background methotrexate were randomized to receive either ABBV-3373 (n = 31) or adalimumab (n = 17). The novel drug at 12 weeks showed a −2.65 reduction in the Disease Activity Score in 28 joints using C-reactive protein, compared with −2.13 for adalimumab. Researchers also predicted ABBV-3373 to be more effective than adalimumab based on in-trial and historical adalimumab data.
“We have great expectations for this molecule,” said Giovanni Adami, MD, PhD, a rheumatologist at the University of Verona, Verona, Italy, who has coauthored several studies on the use of GCs. Plans are underway for a phase 3 study with ABBV-3373.
C5a and Interleukin (IL)-6 Receptor Inhibitors as GC-Sparing Drugs
Investigators in a 2021 paper explored whether the C5a receptor inhibitor avacopan could effectively treat patients with antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis without the need for daily GCs, following treatment with either cyclophosphamide or rituximab. They randomized 331 patients to receive avacopan or prednisone given on a tapering schedule for 20 weeks (60 mg/d tapered to discontinuation by week 21). “Avacopan was noninferior but not superior to prednisone taper with respect to remission at week 26 and was superior to prednisone taper with respect to sustained remission at week 52,” the investigators summarized.
A longer trial should test avacopan’s safety and durability in patients with ANCA-associated vasculitis, they recommended.
Sarilumab, a human monoclonal antibody that binds IL-6 receptor alpha and blocks the IL-6 pathway, yielded good results in the phase 3 SAPHYR trial as an alternative for patients with PMR who relapse while tapering prednisone therapy.
Researchers in the SAPHYR trial randomly assigned 118 patients 1:1 to receive a twice-monthly subcutaneous injection of sarilumab over 52 weeks plus a 14-week prednisone taper or placebo plus a 52-week prednisone taper. Patients in each group received a tapered GC dose initially at 15 mg/d for 2 weeks in a blinded fashion to control for disease at baseline.
Sarilumab effectively sustained remission in patients, significantly reducing the GC dose compared with placebo.
Disease flare after clinical remission took place in 57% of patients in the placebo group, vs 24% in the sarilumab group. “The placebo-treated patients had a fairly traditional 52-week GC taper. The patients treated with sarilumab had a very rapid GC taper,” said lead study author Robert Spiera, MD, director of the Scleroderma, Vasculitis and Myositis Center at the Hospital for Special Surgery, New York City.
In his own practice, Dr. Spiera often treats his patients with new-onset PMR with a fairly rapid GC taper, akin to what was used in SAPHYR, recognizing that a portion of these patients can be successfully treated with a relatively brief course of GCs, although the majority will need to have “rescue” therapy for flares with that approach.
In SAPHYR, everyone had previously flared and started at 15 mg/d prednisone at study entry. “In my practice, I don’t always raise the prednisone to 15 mg for a PMR flare. I raise it to whatever dose is necessary to capture control of polymyalgia rheumatica symptoms as I add sarilumab. Often, that is less than 15 mg,” he clarified.
Patients with giant cell arteritis (GCA) also struggle to taper or stop using GCs. For these patients, the IL-6 receptor alpha inhibitor tocilizumab has demonstrated benefits in shortening the GC-tapering period.
In the GiACTA trial, researchers randomly assigned 251 patients in a 2:1:1:1 ratio with GCA to receive subcutaneous tocilizumab weekly or every other week, combined with a 26-week prednisone taper, or placebo combined with a prednisone taper over a period of either 26 weeks or 52 weeks. Patients in the tocilizumab arms combined with a 26-week prednisone taper had superior results with GC-free remission compared with those who underwent prednisone tapering plus placebo.
Subsequent studies have investigated the use of tocilizumab in shortening GC tapers. One pilot clinical trial assessed the use of tocilizumab monotherapy following ultrashort-term GC treatment (three pulses of 500 mg of methylprednisolone) in 18 patients with new-onset GCA. Researchers found that approximately 70% of patients were able to achieve and maintain disease remission for 52 weeks. One patient developed anterior ischemic optic neuropathy.
Another pilot study of 30 patients with GCA (50% new-onset disease, 50% relapsing disease) concluded that a year of tocilizumab combined with 8 weeks of prednisone could lead to remission. The majority of patients (77% of 30) maintained prednisone-free remission at 52 weeks, and no cases of anterior ischemic optic neuropathy were observed.
“The results of the studies mentioned above are encouraging and suggest that in the setting of IL-6 blockade treatment with tocilizumab, GC tapers shorter than 6 months may be possible. However, in order to be able to recommend short prednisone tapers in GCA, clinical trials comparing the efficacy and safety of different prednisone tapers [such as 8 vs 26 weeks] are required,” said Sebastian H. Unizony, MD, the study’s lead author and an assistant professor at Harvard Medical School and codirector of the Massachusetts General Hospital Rheumatology Vasculitis Program, Boston.
“The last several years have been a breakthrough period in GCA, which started with addition of tocilizumab to the therapeutic armamentarium against this disease and continued with several other agents showing promising results in phase 2 trials [of abatacept, mavrilimumab, and secukinumab] and a recently successful phase 3 trial with upadacitinib,” Dr. Unizony said.

An ongoing phase 2 clinical trial is testing SPI-62 in patients with endogenous Cushing syndrome. “It’s a longer-term trial, so we’re able to see at least an individual patient’s more clinical outcomes such as reversal of Cushing’s-associated myopathy and the ability of patients to discontinue all of their antidiabetic medications and yet still have good glycemic control,” he said.
Another research team from the United Kingdom explored whether AZD4017, an inhibitor of human 11ß-HSD1, could mitigate GC effects. The researchers randomly assigned 32 healthy male volunteers to AZD4017 or placebo, along with prednisolone. They reported a worsening of hepatic insulin sensitivity in the placebo group but not in the AZD4017 group, and protective effects of AZD4017 on markers of lipid metabolism and bone turnover, as well as lowered nighttime blood pressure. The results signified that coadministration of AZD4017 with prednisolone in men could be a way to reduce GC side effects.
In a Japanese phase 1/2 study, 11ß-HSD1 inhibitor S-707106 proved useful as an insulin sensitizer and antisarcopenic and anti-obesity medication in 16 patients with Cushing syndrome and autonomous cortisol secretion.
Novel Antitumor Necrosis Factor (TNF) Antibody Plus GC Receptor Modulator Conjugate
A novel antibody-drug conjugate comprising the anti-TNF monoclonal antibody adalimumab (ABBV-3373) linked to a GC receptor modulator shows promise as a GC alternative.
A notable 2022 study authored by Frank Buttgereit, MD, and other researchers assessed its safety and efficacy in a randomized, double-blind, active-controlled, proof-of-concept trial.
ABBV-3373 “was designed to potentially allow precise targeting of activated immune cells while significantly dampening inflammation and minimizing the systemic side effects associated with glucocorticoids,” according to AbbVie, its manufacturer.
A total of 48 adults with moderate to severe rheumatoid arthritis receiving background methotrexate were randomized to receive either ABBV-3373 (n = 31) or adalimumab (n = 17). The novel drug at 12 weeks showed a −2.65 reduction in the Disease Activity Score in 28 joints using C-reactive protein, compared with −2.13 for adalimumab. Researchers also predicted ABBV-3373 to be more effective than adalimumab based on in-trial and historical adalimumab data.
“We have great expectations for this molecule,” said Giovanni Adami, MD, PhD, a rheumatologist at the University of Verona, Verona, Italy, who has coauthored several studies on the use of GCs. Plans are underway for a phase 3 study with ABBV-3373.
C5a and Interleukin (IL)-6 Receptor Inhibitors as GC-Sparing Drugs
Investigators in a 2021 paper explored whether the C5a receptor inhibitor avacopan could effectively treat patients with antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis without the need for daily GCs, following treatment with either cyclophosphamide or rituximab. They randomized 331 patients to receive avacopan or prednisone given on a tapering schedule for 20 weeks (60 mg/d tapered to discontinuation by week 21). “Avacopan was noninferior but not superior to prednisone taper with respect to remission at week 26 and was superior to prednisone taper with respect to sustained remission at week 52,” the investigators summarized.
A longer trial should test avacopan’s safety and durability in patients with ANCA-associated vasculitis, they recommended.
Sarilumab, a human monoclonal antibody that binds IL-6 receptor alpha and blocks the IL-6 pathway, yielded good results in the phase 3 SAPHYR trial as an alternative for patients with PMR who relapse while tapering prednisone therapy.
Researchers in the SAPHYR trial randomly assigned 118 patients 1:1 to receive a twice-monthly subcutaneous injection of sarilumab over 52 weeks plus a 14-week prednisone taper or placebo plus a 52-week prednisone taper. Patients in each group received a tapered GC dose initially at 15 mg/d for 2 weeks in a blinded fashion to control for disease at baseline.
Sarilumab effectively sustained remission in patients, significantly reducing the GC dose compared with placebo.
Disease flare after clinical remission took place in 57% of patients in the placebo group, vs 24% in the sarilumab group. “The placebo-treated patients had a fairly traditional 52-week GC taper. The patients treated with sarilumab had a very rapid GC taper,” said lead study author Robert Spiera, MD, director of the Scleroderma, Vasculitis and Myositis Center at the Hospital for Special Surgery, New York City.
In his own practice, Dr. Spiera often treats his patients with new-onset PMR with a fairly rapid GC taper, akin to what was used in SAPHYR, recognizing that a portion of these patients can be successfully treated with a relatively brief course of GCs, although the majority will need to have “rescue” therapy for flares with that approach.
In SAPHYR, everyone had previously flared and started at 15 mg/d prednisone at study entry. “In my practice, I don’t always raise the prednisone to 15 mg for a PMR flare. I raise it to whatever dose is necessary to capture control of polymyalgia rheumatica symptoms as I add sarilumab. Often, that is less than 15 mg,” he clarified.
Patients with giant cell arteritis (GCA) also struggle to taper or stop using GCs. For these patients, the IL-6 receptor alpha inhibitor tocilizumab has demonstrated benefits in shortening the GC-tapering period.
In the GiACTA trial, researchers randomly assigned 251 patients in a 2:1:1:1 ratio with GCA to receive subcutaneous tocilizumab weekly or every other week, combined with a 26-week prednisone taper, or placebo combined with a prednisone taper over a period of either 26 weeks or 52 weeks. Patients in the tocilizumab arms combined with a 26-week prednisone taper had superior results with GC-free remission compared with those who underwent prednisone tapering plus placebo.
Subsequent studies have investigated the use of tocilizumab in shortening GC tapers. One pilot clinical trial assessed the use of tocilizumab monotherapy following ultrashort-term GC treatment (three pulses of 500 mg of methylprednisolone) in 18 patients with new-onset GCA. Researchers found that approximately 70% of patients were able to achieve and maintain disease remission for 52 weeks. One patient developed anterior ischemic optic neuropathy.
Another pilot study of 30 patients with GCA (50% new-onset disease, 50% relapsing disease) concluded that a year of tocilizumab combined with 8 weeks of prednisone could lead to remission. The majority of patients (77% of 30) maintained prednisone-free remission at 52 weeks, and no cases of anterior ischemic optic neuropathy were observed.
“The results of the studies mentioned above are encouraging and suggest that in the setting of IL-6 blockade treatment with tocilizumab, GC tapers shorter than 6 months may be possible. However, in order to be able to recommend short prednisone tapers in GCA, clinical trials comparing the efficacy and safety of different prednisone tapers [such as 8 vs 26 weeks] are required,” said Sebastian H. Unizony, MD, the study’s lead author and an assistant professor at Harvard Medical School and codirector of the Massachusetts General Hospital Rheumatology Vasculitis Program, Boston.
“The last several years have been a breakthrough period in GCA, which started with addition of tocilizumab to the therapeutic armamentarium against this disease and continued with several other agents showing promising results in phase 2 trials [of abatacept, mavrilimumab, and secukinumab] and a recently successful phase 3 trial with upadacitinib,” Dr. Unizony said.

. Selective GC receptor agonists and modulators and GC plus hydroxysteroid dehydrogenase inhibitor combination therapy are some of the approaches under consideration.
“There is growing observational data that confirms the GC-sparing effect seen in some of these clinical trials in real-world data,” said Sebastian E. Sattui, MD, assistant professor of medicine and director of the Vasculitis Center at the University of Pittsburgh Medical Center, Pittsburgh.
GC minimization is an important goal, “and the data emerging from these trials should be reassuring for rheumatology providers,” Dr. Sattui said.
HSD-1 Inhibitors Under Study
11ß-Hydroxysteroid dehydrogenase type 1 (11ß-HSD1) is a tissue-specific intracellular modulator of GC action that’s been trialed for a number of rheumatic conditions. “HSD-1 deficiency or inhibition has been consistently associated with reduced GC side effects in mouse and human,” wrote the authors of a study testing the coadministration of HSD-1 inhibitor SPI-62 (clofutriben) with prednisolone in patients with polymyalgia rheumatica (PMR) to measure its impact on efficacy and toxicity.
Lead study author David Katz, PhD, chief scientific officer at Sparrow Pharmaceuticals, presented results at the at the annual European Congress of Rheumatology.
GCs are often the first-line therapy with PMR. However, it’s very difficult for patients to stop taking GCs once they start taking them. The study included patients with PMR who were taking 10 mg/d prednisolone and didn’t require a dose increase. For the study, they continued prednisolone without dose reduction for 4 weeks, receiving either SPI-62 6 mg/d or a matching placebo for 2 weeks.
During SPI-62 treatment, researchers in sequential cohorts maintained daily prednisolone doses at 10 mg, adjusted to 15 mg or adjusted to 20 mg.
A 10-mg dose of prednisolone combined with 6 mg of SPI-62 demonstrated less efficacy compared with placebo but improved upon prednisolone toxicities such as bone formation and resorption biomarkers, lipidemia, and insulin resistance. Doubling the dose to 20 mg prednisolone combined with SPI-62 achieved similar efficacy and maintained improvement of prednisolone toxicity markers.
“In patients with PMR, when we double the dose of prednisolone during coadministration with a potent HSD-1 inhibitor, we are able to have similar stability of symptoms, physical function, and systemic inflammation. At the same time, we are able to show improvements on biomarkers of bone turnover and insulin resistance,” Dr. Katz informed the EULAR 2024 audience.

Infection Co-occurring With Lupus Raises Flare Risk
TOPLINE:
Intercurrent infections are associated with an increased risk for systemic lupus erythematosus (SLE) flares within 3 months, with major infections associated with a 7.4 times higher risk for major flares.
METHODOLOGY:
- The researchers prospectively examined the association between intercurrent infections and subsequent SLE flares in 203 patients (median age, 40 years; 91% women) with SLE from the Amsterdam SLE cohort study.
- SLE flares were defined as an increase in disease activity combined with an intensification of immunosuppressive therapy. They were categorized into minor and major flares according to the severity and required treatment.
- Major infections were defined as those requiring hospital admission or intravenous antibiotic therapy, while minor infections did not require hospital admission.
- The risk interval for the occurrence of a disease flare was defined as 3 months from the index date of an infection.
- Patients were followed for a median duration of 6 years.
TAKEAWAY:
- The incidence of major and minor infections was 5.3 (95% CI, 4.1-6.9) and 63.9 per 100 patient-years (95% CI, 59.3-69.0), respectively.
- Intercurrent infections were associated with a 1.9 times higher risk for SLE flares within 3 months (95% CI, 1.3-2.9).
- Intercurrent infections were significantly associated with minor SLE flares (hazard ratio, 1.9; 95% CI, 1.2-3.0) but not with major flares.
- Major infections were linked to a 7.4 times higher risk for major SLE flares within 3 months (95% CI, 2.2-24.6).
IN PRACTICE:
“This finding stresses the importance of awareness and strict monitoring of disease activity in patients with SLE suffering a major infection and prompt adequate treatment in case of the development of a disease flare,” the authors wrote.
SOURCE:
The study was led by Fatma el Hadiyen, Amsterdam Rheumatology and Immunology Center, Amsterdam University Medical Center in the Netherlands. It was published online on July 1, 2024, in Lupus Science & Medicine.
LIMITATIONS:
The reliance on patient recall for minor infections may have introduced recall bias. The small number of patients with identified causative organisms limited the generalizability of the findings. The Bootsma criteria were used for defining SLE flares, which may not align with more recent international standards.
DISCLOSURES:
No specific funding source was reported. One author reported receiving personal fees from various pharmaceutical companies outside the submitted work.
This article was created using several editorial tools, including AI, as part of the process. Human editors reviewed this content before publication. A version of this article appeared on Medscape.com.
