Conference Coverage

As the use of biologics for dermatologic conditions has increased, so have questions from patients about their safety during pregnancy and lactation, their effects on fertility, and potential effects on the developing fetus and the child’s development.

“I get asked a lot about fertility,” Vivian Shi, MD, associate professor of dermatology at the University of Arkansas, Little Rock, said at MedscapeLive’s Women’s and Pediatric Dermatology Seminar. Patients want to know, she said, if they go on a specific drug, whether it will affect their chances of conceiving and what else they need to know about safety.

She told the audience what she tells her patients: The answers are not complete but are evolving at a steady pace.

“Putting this talk together was kind of like a scavenger hunt,” said Dr. Shi, who gathered data from pregnancy exposure registries, published research, the Food and Drug Administration, and other sources on biologics. As more studies emerge each year, she said, recommendations will become stronger for considering treatment by certain biological drugs, taking into account effects on fertility, pregnancy, lactation, and the infant.

Among the biologics commonly used in dermatology are:

• Tumor necrosis factor (TNF) inhibitors (etanercept, adalimumab, infliximab, certolizumab).
• Interleukin (IL)–12 and -23 antagonist (ustekinumab).
• IL-17 antagonists (ixekizumab, secukinumab, brodalumab).
• IL-23 antagonists (risankizumab, tildrakizumab, guselkumab).
• IL-4, -13 antagonist (dupilumab) and IL-13 antagonist (tralokinumab).
• CD20-directed cytolytic antibody (rituximab).

To help with decision-making, Dr. Shi discussed the relatively new FDA labeling regulations as well as pregnancy exposure registries, research studies, and recommendations.
 

FDA pregnancy risk summaries

Under the previous system of classification of drugs in pregnancy, the FDA rated drugs as A, B, C, D, X. These categories ranged from showing no risks to the fetus to clear risk, but were oversimplistic and confusing, Dr. Shi said. Category C was especially confusing, as a drug with no animal or human data was put in the same category as a drug with adverse fetal effects on animals, she noted.

However, effective June 30, 2015, the FDA replaced pregnancy categories with risk summaries by medication. As of June, 2020, all prescription drugs were to remove pregnancy letter labeling. The risk summaries note human data when they are available and also note when no data are available. This information, Dr. Shi said, originates from many sources, including studies published in the medical literature, postmarketing studies conducted by companies, and pregnancy exposure registries, conducted by some companies and others. The FDA does not endorse any specific registries, but does post a list of such registries. Another helpful resource, she said, is Mother to Baby, a service of the nonprofit Organization of Teratology Information Specialists (OTIS).



Known, not known

Citing published literature, Dr. Shi said that TNF inhibitors have the most robust safety data from preconception to after birth. Less is known, she said, about the reproductive safety effects of other biologics used for dermatologic conditions, as they are newer than the anti-TNF medicines.

She reviewed a variety of research studies evaluating the safety of biologics during pregnancy and beyond. Highlights include results from a large registry, the Psoriasis Longitudinal Assessment and Registry (PSOLAR), of 298 pregnancies in about 220 women from 2007 to 2019, looking at 13 different biologics. The overall and live-birth outcomes in the women on biologics for psoriasis were similar to those for the general population and the rate of congenital anomalies was 0.8%, researchers reported in 2021, lower than the generally cited annual figure of U.S. births.

Studies evaluating biologics for nondermatologic conditions suggest safety. A prospective cohort study of women who took adalimumab in pregnancy (for rheumatoid arthritis or Crohn’s disease) found no increased risk for birth defects. In another study looking at women who were breastfeeding, researchers found no increased risk of infections or delay in developmental milestones in the children of women taking biologics for inflammatory bowel disease, compared with those not on the medications.

A report using data from the World Health Organization concludes that dupilumab appears to be safe during pregnancy, based on an evaluation of 36 pregnancy-related reports among more than 37,000 unique adverse event reports related to dupilumab in a global database.

Recommendations about biologic use from different organizations don’t always mesh, Dr. Shi said, noting that European guidelines tend to be stricter, as some reviews show.

If a mother is exposed to any biologic therapy other than certolizumab during the third trimester, after 27 weeks, Dr. Shi said, “you want to consider avoiding a live vaccine for the first 6 months of the baby’s life.” It turns out, she said, the only recommended live vaccine during that period is the rotavirus vaccine, and she suggests doctors recommend postponing that one until the babies are older if women have been on biologics other than certolizumab.

Her other take-home messages: TNF inhibitors have the most robust safety data from before conception through lactation. Under current guidelines, certolizumab is viewed as the safest to use throughout pregnancy. Dr. Shi’s message to her colleagues fielding the same questions she gets from patients: “There is more data coming out every year. Ultimately, we will have better information to inform our patients.”

At the conference, Lawrence F. Eichenfield, MD, a course director and professor of dermatology and pediatrics at the University of California, San Diego and Rady Children’s Hospital San Diego, encouraged Dr. Shi to write up her presentation as a resource for other dermatologists – which she said is in progress.

French investigators are warning about using acetaminophen in patients with cancer who are taking immune checkpoint blockers.

The team found a strong association between the use of acetaminophen and a decreased response to immune checkpoint inhibitors in a study of three clinical cohorts involving more than 600 patients with advanced cancer.

Patients who took acetaminophen at the start of immunotherapy – with acetaminophen exposure confirmed by plasma testing – were found to have worse overall survival and progression-free survival than patients who did not take the analgesic. Multivariate analysis confirmed the association independent of other prognostic factors. “It is unlikely that our data are the result of bias or unmeasured confounding,” the authors comment.

The findings “present a compelling case for caution” in using acetaminophen in patients with cancer who are receiving immune checkpoint blockers, senior investigator Antoine Italiano, MD, PhD, a medical oncologist at the University of Bordeaux (France), and colleagues concluded.

The study was presented at the annual meeting of the American Society of Clinical Oncology and published simultaneously in Annals of Oncology.

“Patients with advanced cancer taking [acetaminophen] during immunotherapy experience worse clinical outcomes, which suggests that [acetaminophen] decreases T cell–mediated antitumor immunity,” the authors comment.

They also report bench research and blood studies in four healthy volunteers, which showed an up-regulation of immunosuppressive regulatory T cells (Tregs) with acetaminophen, and other findings that together suggest that acetaminophen undermines the antitumor immune processes by which checkpoint inhibitors work.
 

Reconsider acetaminophen pretreatment

After hearing Dr. Italiano present the results at the meeting, a Polish oncologist in the audience said he was concerned that his clinic premedicates with acetaminophen before immune checkpoint blockade and wanted to know if they should stop doing it.

“I don’t think inducing Tregs ... in cancer patients is a good approach. I do a lot of clinical trials,” and “I do not understand why in several cases sponsors required mandatory premedication with acetaminophen. I think ... we should reconsider this approach,” Dr. Italiano said.

There’s precedence for the findings. Acetaminophen – also known as paracetamol – has been shown in some studies to limit immune cell proliferation, T-cell–dependent antibody response, and viral clearance, among other things. After a randomized trial showing blunted responses to vaccines in individuals who were taking acetaminophen, the World Health Organization recommended in 2015 against concurrent use of acetaminophen with vaccines.

Steroids, antibiotics, and proton pump inhibitors have also recently been shown to worsen outcomes with pembrolizumab, noted invited discussant, Margaret Gatti-Mays, MD, a medical oncologist at Ohio State University, Columbus.

“We are starting to understand that ... commonly used medications may have a larger impact on the efficacy and toxicity of immune checkpoint blockade than historically seen with chemotherapy,” she said.

However, she expressed some uncertainty over the French findings, as she was concerned that even the multivariate analysis didn’t completely rule out that acetaminophen users had worse disease to begin with and so would be expected to have worse outcomes.

She was also unsure of how much acetaminophen is too much.

Acetaminophen has a half-life of around 3 hours or less, where the immune checkpoint inhibitors have a half-life of around 20 days or more.

Given that, Dr. Gatti-Mays wondered whether “a single dose of acetaminophen [is] enough to derail the benefit of checkpoint inhibition? Does exposure need to be continuous?”

She allowed that acetaminophen use may turn out to be one more of the many patient-level factors emerging lately – such as chronic stress, diet, body flora, and physiological age, among others – that might help explain why checkpoint inhibition works in only about 20% of eligible patients with cancer.
 

Study details

Dr. Italiano and his team analyzed plasma samples from 297 participants in the CheckMate 025 trial of nivolumab for renal cancer; 34 participants in the BIP study into actionable molecular alterations in cancer; and 297 participants in the PREMIS immune-related adverse events study. The patients in these last two studies had a variety of cancers and were taking various agents.

All 628 patients were on checkpoint inhibitors. The investigators divided them according to who had acetaminophen or its metabolite acetaminophen glucuronide in their plasma when they started checkpoint inhibition and those who did not.

In CheckMate 025, overall survival was significantly worse among participants who had detectable acetaminophen or its metabolite in plasma (hazard ratio, 0.67; P = .004).

None of the acetaminophen-positive participants in the BIP study responded to checkpoint blockade, compared with almost 30% of those who were negative. Acetaminophen-positive participants also trended toward worse progression-free survival (median, 1.87 vs. 4.72 months) and overall survival (median, 7.87 vs. 16.56 months).

In PREMIS, progression-free survival was a median of 2.63 months in the acetaminophen group versus 5.03 months in negative participants (P = .009); median overall survival was 8.43 months versus 14.93 months, respectively (P < .0001).

A multivariate analysis was performed in PREMIS. Acetaminophen exposure was associated with both progression-free survival (hazard ratio, 1.43; P =.015) and overall survival (HR, 1.78; P =.006) independently of performance status, liver metastases, bone metastases, number of metastases sites, tumor type, number of previous lines of treatment, steroid/antibiotic use, lactate dehydrogenase levels, and other factors.

There was no funding for the work. Dr. Italiano is a consultant for AstraZeneca, Bayer, Chugai, Deciphera, Merck, Parthenon, Roche, and Springworks, He also has grants from AstraZeneca, Bayer, Bristol-Myers Squibb, Merck, MSD, Novartis, Pharmamar, and Roche.

Moderate to severe sleep disturbances and severe fatigue affect up to 40% of patients with long COVID, or post-acute sequelae of SARS-CoV-2 infection (PASC). Such disturbances are especially common among Black people, new research shows.

The “high” prevalence of moderate to severe sleep disturbances is “alarming,” study investigator Cinthya Pena Orbea, MD, sleep specialist at the Cleveland Clinic, said in an interview.

The findings were presented at the annual meeting of the Associated Professional Sleep Societies.

Dr. Pena and colleagues analyzed data on 962 patients with PASC seen at the Cleveland Clinic ReCOVer Clinic between February 2021 and April 2022.

More than two-thirds of patients (67.2%) reported at least moderate fatigue, while 21.8% reported severe fatigue, Dr. Pena reported.

In addition, 41.3% reported at least moderate sleep disturbances, while 8% of patients reported severe sleep disturbances, including insomnia, “which may impair quality of life,” Dr. Pena said.

Obesity, mood disorders, and Black race emerged as contributors to problems with sleep and fatigue after COVID.

Notably, after adjusting for demographics, Black race conferred threefold higher odds of moderate to severe sleep disturbances.

“We don’t know why this is, and one of our next steps is to better understand race-specific determinants of sleep disturbances after COVID and create targeted interventions,” Dr. Pena said.

How long after COVID the fatigue and sleep problems last “remains uncertain,” Dr. Pena acknowledged. However, in her clinical experience with therapy, patients’ sleep and fatigue may improve after 6 or 8 months.

Ruth Benca, MD, PhD, cochair of the Alliance for Sleep, is not surprised by the Cleveland Clinic findings.

“Sleep disturbances and fatigue are part of the sequelae of COVID,” Dr. Benca, who was not involved in the study, said in an interview.

“We know that people who have had COVID have more trouble sleeping afterwards. There is the COVID insomnia created in all of us just out of our worries, fears, isolation, and stress. And then there’s an actual impact of having the infection itself on worsening sleep,” said Dr. Benca, with Wake Forest University and Atrium Health Wake Forest Baptist, both in Winston-Salem, N.C.

The study had no specific funding. The authors have disclosed no relevant financial relationships. Dr. Benca is a consultant for Idorsia Pharmaceuticals.

Social engagement such as participation in community or school-based activities may mitigate psychosis risk in susceptible youth living in disadvantaged communities, new research suggests.

A study of more than 170 young participants showed reduced hippocampal volume in those living in poor neighborhoods who had low social engagement versus their peers with greater community engagement.

“These findings demonstrate the importance of considering broader environmental influences and indices of social engagement when conceptualizing adversity and potential interventions for individuals at clinical high risk for psychosis,” co-investigator Benson Ku, MD, a postdoctoral fellow and psychiatry resident at Emory University School of Medicine, Atlanta, told this news organization.

A personal connection

It’s well known that growing up in low-income housing is associated with lower hippocampal volume and an increased risk for schizophrenia, said Dr. Ku.

“The inverse relationship between poverty and hippocampal gray matter volume has [also] been shown to be mediated by social stress, which can include things like lack of parental caregiving and stressful life events,” he added.

Dr. Ku himself grew up in a socioeconomically disadvantaged family in Queens, New York, and he said he had initially performed poorly in school. His early experiences have helped inform his clinical and research interests in the social determinants of mental health.

“I found community support in the Boys’ Club of New York and a local Magic Shop near where I lived, which helped me thrive and become the successful man I am today. I have also heard from my patients how their living conditions and neighborhood have significantly impacted their mental health,” Dr. Ku said.

“A more in-depth understanding of the social determinants of mental health has helped build rapport and empathy with my patients,” he added.

To explore the association between neighborhood poverty, social engagement, and hippocampal volume in youth at high risk for psychosis, the researchers analyzed data from the North American Prodrome Longitudinal Study Phase 2, a multisite consortium.

The researchers recruited and followed up with help-seeking adolescents and young adults from diverse neighborhoods. The analysis included 174 youth, ages 12-33 years, at high clinical risk for psychosis.

Hippocampal volume was assessed using structural MRI. Neighborhood poverty was defined as the percentage of residents with an annual income below the poverty level in the past year.

Social engagement was derived from the desirable events subscale items of the Life Events Scale. These activities included involvement in a church or synagogue; participation in a club, neighborhood, or other organization; taking a vacation; engaging in a hobby, sport, craft, or recreational activity; acquiring a pet; or making new friends.
 

Lower hippocampal volume

Results showed neighborhood poverty was associated with reduced hippocampal volume, even after controlling for several confounders, including race/ethnicity, family history of mental illnesses, household poverty, educational level, and stressful life events.

Among the 77 participants with lower social engagement, which was defined as three or fewer social activities, neighborhood poverty was associated with reduced hippocampal volume.

However, in the 97 participants who reported greater social engagement, which was defined as four or more social activities, neighborhood poverty was not significantly associated with hippocampal volume.

“It is possible that social engagement may mitigate the deleterious effects of neighborhood poverty on brain morphology, which may inform interventions offered to individuals from disadvantaged neighborhoods,” Dr. Ku said.

“If replication of the relationships between neighborhood poverty, hippocampal volume, and social engagement is established in other populations in longitudinal studies, then targeted interventions at the community level and increased social engagement may potentially play a major role in disease prevention among at-risk youth,” he said.

Dr. Ku noted social engagement might look different in urban versus rural settings.

“In urban areas, it might mean friends, clubs, neighborhood organizations, etc. In rural areas, it might mean family, pets, crafts, etc. The level of social engagement may also depend on neighborhood characteristics, and more research would be needed to better understand how geographic area characteristics – remote, rural, urban – affects social engagement,” he said.
 

Interesting, innovative

Nagy Youssef, MD, PhD, director of clinical research and professor of psychiatry, Ohio State University College of Medicine, Columbus, said the study suggests “social engagement may reduce the negative effect of poverty in this population, and if replicated in a larger study, could assist and be a part of the early intervention and prevention in psychosis.”

Overall, “this is an interesting and innovative study that has important medical and social implications and is a good step toward helping us understand these relationships and mitigate and prevent negative consequences, as best as possible, in this population,” said Dr. Youssef, who was not part of the research.

The analysis was supported by a grant from the National Institute of Mental Health to the North American Prodrome Longitudinal Study. Dr. Ku and Dr. Youssef report no relevant financial relationships.

The effectiveness of hormonal contraceptives, including the pill and mini-pill, may be compromised by sugammadex, a drug widely used in anesthesia for reversing neuromuscular blockade induced by rocuronium or vecuronium.

Yet women are not routinely informed that the drug may make their contraception less effective, delegates at Euroanaesthesia, the annual meeting of the European Society of Anaesthesiology and Intensive Care in Milan were told.

New research presented at the meeting supports the authors’ experience that “robust methods for identifying at-risk patients and informing them of the associated risk of contraceptive failures is not common practice across anesthetic departments within the United Kingdom, and likely further afield.”

This is according to a survey of almost 150 anesthetic professionals, including consultants, junior doctors, and physician assistants, working at University College London Hospitals NHS Foundation Trust.

Dr. Neha Passi, Dr. Matt Oliver, and colleagues at the trust’s department of anesthesiology sent out a seven-question survey to their 150 colleagues and received 82 responses, 94% of which claimed awareness of the risk of contraceptive failure with sugammadex. However, 70% of the respondents admitted that they do not routinely discuss this with patients who have received the drug.
 

Risk with all forms of hormonal contraceptive

Yet current guidance is to inform women of child-bearing age that they have received the drug and, because of increased risk of contraceptive failure, advise those taking oral hormonal contraceptives to follow the missed pill advice in the leaflet that comes with their contraceptives. It also counsels that clinicians should advise women using other types of hormonal contraceptive to use an additional nonhormonal means of contraception for 7 days.

The study authors also carried out a retrospective audit of sugammadex use in the trust and reported that during the 6 weeks covered by the audit, 234 patients were administered sugammadex of whom 65 (28%) were women of childbearing age. Of these, 17 had a medical history that meant they weren’t at risk of pregnancy, but the other 48 should have received advice on the risks of contraceptive failure – however there was no record in the medical notes of such advice having been given for any of the at-risk 48 women.

While sugammadex is the only anesthetic drug known to have this effect, it is recognized to interact with progesterone and so may reduce the effectiveness of hormonal contraceptives, including the progesterone-only pill, combined pill, vaginal rings, implants, and intrauterine devices.

Dr. Passi said: “It is concerning that we are so seldom informing patients of the risk of contraceptive failure following sugammadex use.

“Use of sugammadex is expected to rise as it becomes cheaper in the future, and ensuring that women receiving this medicine are aware it may increase their risk of unwanted pregnancy must be a priority.”

She added: “It is important to note, however, that most patients receiving an anesthetic do not need a muscle relaxant and that sugammadex is one of several drugs available to reverse muscle relaxation.”

Dr. Oliver said: “We only studied one hospital trust but we expect the results to be similar in elsewhere in the U.K.”

In response to their findings, the study’s authors have created patient information leaflets and letters and programmed the trust’s electronic patient record system to identify “at-risk” patients and deliver electronic prompts to the anesthetists caring for them in the perioperative period.

COPENHAGEN – Most patients with immune-mediated inflammatory diseases (IMID) should not be considered at high risk for severe COVID-19 breakthrough infections, but those on anti-CD20 therapy are the exception, data from a large prospective, cohort study show.

“Overall, the data are reassuring, with conventional risk factors, such as age, and comorbidities seeming to be more important regarding risk of severe COVID-19 breakthrough infections than rheumatic disease or immunosuppressant medication,” said Laura Boekel, MD, from Amsterdam UMC, who presented the study at the annual European Congress of Rheumatology.

But, she added, there was an exception for anti-CD20 therapy. “This is especially relevant for patients with conventional risk factors that might accumulate, and rheumatologists might want to consider alternative treatment options if possible. It is important to inform patients about the risks of anti-CD20.”

Another study, presented during the same session at the congress by Rebecca Hasseli, MD, from the University of Giessen (Germany) saw no deaths and no COVID-19 related complications in a cohort of triple-vaccinated patients with inflammatory rheumatic diseases, despite a higher median age and a higher rate of comorbidities compared to double-vaccinated and unvaccinated cohorts.

Ingrid Jyssum, MD, from Diakonhjemmet Hospital, Oslo, who presented results of the Nor-vaC study investigating the impact of different DMARDs on the immunogenicity of a third COVID-19 vaccine dose, welcomed the research by Dr. Boekel and Dr. Hasseli.

“The findings of Hasseli are interesting in the light of our data on serological response after the third dose, with a lack of breakthrough infections after three doses corresponding well to the robust antibody response that we found in our cohort,” she remarked. “This is very reassuring for our patients. Our own work together with the findings of Hasseli and Boekel demonstrate that additional vaccine doses are important to keep this population well protected against severe COVID-19 infections.”

The Nor-vaC study was conducted with a cohort of 1,100 patients with inflammatory joint and bowel diseases. “These patients had attenuated antibody responses after two vaccine doses; however, we found that a third vaccine dose brought the humoral response in patients up to the antibody levels that healthy controls had after two doses,” said Dr. Jyssum. “In addition, we found that the decline in antibodies after the third dose was less than the decline seen after the second dose. Importantly, the third dose was safe in our patients, with no new safety issues.”
 

Breakthrough infections and immunosuppressants

“Like the rest of the world, we were wondering if our patients were at increased risk of COVID-19, and if the immunosuppressants used by these patients influenced their risk,” said Dr. Boekel.

The researchers compared both the incidence and severity of COVID-19 breakthrough infections with the SARS-CoV-2 Delta variant in a population of fully vaccinated IMID patients taking immunosuppressants and controls (IMID patients not taking immunosuppressants and healthy controls).

Two large ongoing, prospective, multicenter cohort studies provided pooled data collected between February and December 2021 using digital questionnaires, standardized electronic case record forms, and medical files.

Finger-prick tests were used to collect blood samples that were analyzed after vaccination against SARS-CoV-2 for anti–receptor-binding domain (RBD) antibodies, and antinucleocapsid antibodies to identify asymptomatic breakthrough infections. Any associations between antibodies and the incidence of breakthrough infections were generated, and results were adjusted for sex, cardiovascular disease, chronic pulmonary disease, obesity, and vaccine type.

The analysis included 3,207 IMID patients taking immunosuppressants, and 1,810 controls (985 IMID patients not on immunosuppressants and 825 healthy controls).

Initially, Dr. Boekel and her colleagues looked at incidence of infections and hospitalizations prior to vaccination, and then after vaccination, which was the main aim of the study.

Prior to vaccination, hospitalization risk for COVID-19 was somewhat higher for IMID patients overall compared with controls, reported Dr. Boekel. “But those treated with anti-CD20 therapy, demonstrated much greater risk for severe disease.”

After the SARS-CoV-2 vaccination campaign began, the researchers then looked at how immunosuppressants influenced humoral response to SARS-CoV-2 vaccination.

“Anti-CD20 therapy showed the greatest impact on humoral immune response after SARS-CoV-2 vaccination,” said Dr. Boekel. Other immunosuppressant drugs had variable effects on humoral and cellular immunity. 

Once they had established that immunosuppressant drugs impaired immune responses to SARS-CoV-2 vaccination, the researchers wanted to determine if this affected clinical outcomes. Blood samples taken 28 days after the second vaccination enabled Dr. Boekel and her colleagues to see if antibody production was associated with breakthrough infections.   

Breakthrough infections were seen in 5% of patients on immunosuppressants, 5% of patients not on immunosuppressants, and 4% of healthy controls. Also, asymptomatic COVID-19 breakthrough cases were comparable between IMID patients taking immunosuppressants and controls, at 10% in each group.

“We saw that the incidence [of getting COVID-19] was comparable between groups, independent of whether they were receiving immunosuppressants or not, or healthy controls. However, if they developed antibodies against the two vaccinations the chance of getting infected was lower,” reported Dr. Boekel.

Hospitalization (severe disease) rates were also comparable between groups. “Patients with rheumatic diseases, even when treated with immunosuppressants were not at increased risk of severe disease from Delta breakthrough infections,” added the researcher. “Cases that were hospitalized were mainly elderly and those with comorbidities, for example cardiovascular disease and cardiopulmonary disease.”

Hospital admissions were 5.4% in patients on immunosuppressants, 5.7% in those not on immunosuppressants, and 6% in health controls.

However, once again, there was one exception, Dr. Boekel stressed. “Patients treated with anti-CD20 therapy were at increased risk of severe disease and hospitalization.”

Omicron variant has a different transmissibility than Delta, so the researchers continued the study looking at the Omicron variant. The data “were mostly reassuring,” said Dr. Boekel. “As expected, hospitalization rates decreased overall, with the exception of patients on anti-CD20 therapy where, despite overall reduced pathogenicity, patients remain at increased risk.”

She said that they were awaiting long-term data so the data reflect only short-term immunity against Omicron. “However, we included many elderly and patients with comorbidities, so this made the analysis very sensitive to detect severe cases,” she added.

Breakthrough infection among double- and triple-vaccinated patients

A lower rate of COVID-19 related complications and deaths were seen in patients who were triple-vaccinated against SARS-CoV-2, than in double-vaccinated or unvaccinated patients, despite the former having more comorbidities and use of rituximab (Rituxan), said Dr. Hasseli.

“These data support the recommendation of booster vaccination to reduce COVID-19-related mortality in patients with inflammatory rheumatic diseases [IRDs],” she said.

“A small number of COVID-19 cases were seen in patients with IRD after vaccinations, and in a few cases, hospitalizations were required. Breakthrough infections were mostly seen in patients on B-cell depletion therapy,” she added.

Dr. Hasseli and her colleagues looked at the characteristics and outcomes of SARS-CoV-2 breakthrough infections among double- and triple-vaccinated patients with IRD.

“We wanted to understand if patients with IRD are protected in the same way as the general population following vaccination, given that these patients receive drugs that might impair the immune response,” she explained.

Data for analysis were drawn from the German COVID-19-IRD registry covering February 2021 and January 2022, and patients who were double- or triple- vaccinated against COVID-19 either 14 days or more prior to a SARS-CoV-2 infection were included. Type of IRD, vaccine, immunomodulation, comorbidities, and outcome of the infection were compared with 737 unvaccinated IRD patients with COVID-19. Those with prior COVID-19 were excluded.

Cases were stratified by vaccinations status: unvaccinated (1,388 patients, median age 57 years); double vaccinated (462, 56 years) and triple vaccinated (301, 53 years). Body mass index was similar across groups (25-26 kg/m²), and time between SARS-CoV-2 infection and last vaccination was 156 days in double-vaccinated patients, and 62 days in triple-vaccinated patients.

Patients had rheumatoid arthritis in 44.7% and 44.4% of unvaccinated and double-vaccinated patients respectively, but fewer triple-vaccinated patients had RA (37.2%). Triple vaccination was seen in 32.2% of patients with spondyloarthritis, 16.6% connective tissue diseases, 5.3% other vasculitis, and 3.3% ANCA-associated vasculitis. Of triple-vaccinated patients, 26.2% were treated with tumor necrosis factor-alpha (TNF-alpha) inhibitors, and 6.3% with rituximab, while 5.3% were not on immunomodulation. At least 25% were treated with glucocorticoids, reported Dr. Hasseli.

“Arterial hypertension and diabetes, that might be risk factors for COVID-19, were less frequently reported in triple-vaccinated patients. More patients in the double-vaccinated group [42.9%] than the triple-vaccinated [23.8%] reported absence of relevant comorbidities,” she said.

COVID-19 related complications were less often reported in double- and triple-vaccinated groups with hospitalizations at 9.5% and 4.3% in double and triple-vaccinated people respectively.

Dr. Boekel and Dr. Hasseli report no relevant conflicts of interest.

COPENHAGEN – Most patients with immune-mediated inflammatory diseases (IMID) should not be considered at high risk for severe COVID-19 breakthrough infections, but those on anti-CD20 therapy are the exception, data from a large prospective, cohort study show.

“Overall, the data are reassuring, with conventional risk factors, such as age, and comorbidities seeming to be more important regarding risk of severe COVID-19 breakthrough infections than rheumatic disease or immunosuppressant medication,” said Laura Boekel, MD, from Amsterdam UMC, who presented the study at the annual European Congress of Rheumatology.

But, she added, there was an exception for anti-CD20 therapy. “This is especially relevant for patients with conventional risk factors that might accumulate, and rheumatologists might want to consider alternative treatment options if possible. It is important to inform patients about the risks of anti-CD20.”

Another study, presented during the same session at the congress by Rebecca Hasseli, MD, from the University of Giessen (Germany) saw no deaths and no COVID-19 related complications in a cohort of triple-vaccinated patients with inflammatory rheumatic diseases, despite a higher median age and a higher rate of comorbidities compared to double-vaccinated and unvaccinated cohorts.

Ingrid Jyssum, MD, from Diakonhjemmet Hospital, Oslo, who presented results of the Nor-vaC study investigating the impact of different DMARDs on the immunogenicity of a third COVID-19 vaccine dose, welcomed the research by Dr. Boekel and Dr. Hasseli.

“The findings of Hasseli are interesting in the light of our data on serological response after the third dose, with a lack of breakthrough infections after three doses corresponding well to the robust antibody response that we found in our cohort,” she remarked. “This is very reassuring for our patients. Our own work together with the findings of Hasseli and Boekel demonstrate that additional vaccine doses are important to keep this population well protected against severe COVID-19 infections.”

The Nor-vaC study was conducted with a cohort of 1,100 patients with inflammatory joint and bowel diseases. “These patients had attenuated antibody responses after two vaccine doses; however, we found that a third vaccine dose brought the humoral response in patients up to the antibody levels that healthy controls had after two doses,” said Dr. Jyssum. “In addition, we found that the decline in antibodies after the third dose was less than the decline seen after the second dose. Importantly, the third dose was safe in our patients, with no new safety issues.”
 

Breakthrough infections and immunosuppressants

“Like the rest of the world, we were wondering if our patients were at increased risk of COVID-19, and if the immunosuppressants used by these patients influenced their risk,” said Dr. Boekel.

The researchers compared both the incidence and severity of COVID-19 breakthrough infections with the SARS-CoV-2 Delta variant in a population of fully vaccinated IMID patients taking immunosuppressants and controls (IMID patients not taking immunosuppressants and healthy controls).

Two large ongoing, prospective, multicenter cohort studies provided pooled data collected between February and December 2021 using digital questionnaires, standardized electronic case record forms, and medical files.

Finger-prick tests were used to collect blood samples that were analyzed after vaccination against SARS-CoV-2 for anti–receptor-binding domain (RBD) antibodies, and antinucleocapsid antibodies to identify asymptomatic breakthrough infections. Any associations between antibodies and the incidence of breakthrough infections were generated, and results were adjusted for sex, cardiovascular disease, chronic pulmonary disease, obesity, and vaccine type.

The analysis included 3,207 IMID patients taking immunosuppressants, and 1,810 controls (985 IMID patients not on immunosuppressants and 825 healthy controls).

Initially, Dr. Boekel and her colleagues looked at incidence of infections and hospitalizations prior to vaccination, and then after vaccination, which was the main aim of the study.

NATIONAL HARBOR, MD. – Positive data support autologous hematopoietic stem-cell transplantation in patients with multiple sclerosis (MS), a neurologist told colleagues, and it’s a “reasonable option for people that have largely failed other disease-modifying options.” But, he said, it remains unclear which patients should undergo the procedure.

An especially pressing question is “whether transplant is an alternative to our high-efficacy disease-modifying therapies” (DMTs) in some high-risk patients, Jeffrey A. Cohen, MD, director of experimental therapeutics at Cleveland Clinic’s Mellen Center, said in a presidential lecture at the annual meeting of the Consortium of Multiple Sclerosis Centers.

A handful of ongoing randomized controlled trials will bring answers, he said.

Stem cell therapy exists because there are gaps in MS treatment, Dr. Cohen said. “We have now more than 20 medications. However, none of these therapies is completely effective in all patients. In particular, there are some patients with very active disease who continue to have relapses or new MRI lesion activity despite treatment with all of the available therapies.”

And in progressive MS, the efficacy of a couple of agents is modest and mainly for people with ongoing focal lesion activity, he said. “Finally, all of these currently available therapies are intended primarily to prevent the accumulation of damage, and none of them directly promotes repair. So despite our progress in the field, there still are a number of unmet needs.”
 

‘Rebooting’ the immune system

Several types of stem cell therapy exist, including remyelination and anti-inflammatory therapy, Dr. Cohen said. In his lecture, he focused on immunoablative or myeloablative therapy followed by autologous hematopoietic stem cell transplantation.

This “complicated, multistep procedure” involves first eliminating the immune system to get rid of pathogenic inflammatory cells. This “big component is actually the therapy for MS. It’s also the step that has the most potential complications,” he said.

According to Dr. Cohen, the next step has been described as “rebooting” the immune system.

Does this procedure help patients with MS? In relapsing MS, reports suggest there’s “almost complete abrogation of disease activity following transplant,” he said, “a benefit that’s lasted 5-10-15 years. In addition, there’s also a benefit on the accumulation of CNS damage as measured by whole brain atrophy.”

Recent data, he said, suggests that MS patients most likely to benefit are young, developed MS relatively recently, are still ambulatory, and have highly active MS despite treatment with first- and second-line agents.

However, there have only been two randomized controlled trials of stem cell transplantation versus DMT, and Dr. Cohen said both studies have limitations. The first one, from 2015, is very small, with just 21 subjects. The second study – from 2019 – is larger (n = 103), but some patients weren’t taking higher-efficacy DMTs.

Other research is more promising: Dr. Cohen highlighted a 2017 analysis that found patients with relapsing/remitting MS who underwent stem-cell transplantation were more likely to be symptom-free at 2 years (78%-83%) than those who took DMTs in clinical trials (13%-46%).
 

Clinical concerns

As for side effects of stem cell transplantation, Dr. Cohen said, “most patients have some adverse effects during the procedure itself. There may be an MS relapse or pseudorelapses in association with the mobilization and the conditioning regimens.”

A wide range of other adverse effects is possible before the immune system is reconstituted, he said, including reactivation of various virus infections, such as HPV, CMV or EPV (Epstein-Barr virus), secondary autoimmune phenomenon, and secondary malignancy. EPV infection is also common after transplant, and is “probably the most troublesome posttransplant complication from a management point of view,” he said.

“Thankfully, once the patient ... recovers from the transplant procedure, late adverse effects are relatively uncommon, the most common of which would be infertility,” he said. “There have been some reports of successful pregnancies following transplant, but it’s important to advise people who are considering transplant that most men and women have infertility after the procedure. So if they desire to have children afterward, they need to be counseled on necessary preparations to do that.”

What about progressive multifocal leukoencephalopathy (PML), which seems a possible risk because of the suppression of the immune system? Dr. Cohen is aware of one case linked to a stem-cell transplant, and it may not have been caused by the procedure.

Cost is another potential obstacle, he noted. The National Multiple Sclerosis Society estimates that autologous hematopoietic stem cell transplants cost $150,000 on average in the U.S., although the expense varies widely.
 

Unanswered questions

Moving forward, Dr. Cohen said it remains unclear how these procedures fare against the newest generations of DMTs in MS. Five phase 3 randomized controlled trials are now trying to clarify the matter, he said, by pitting stem-cell transplantation against various MS drugs – alemtuzumab, cladribine, natalizumab, ocrelizumab, and rituximab.

There are also unanswered questions about the best conditioning regimens in the transplants, he said, and lack of clarity about where to draw the line between eligible and ineligible patients with MS. “How many DMTs does the person have to fail? What’s the upper level of disability beyond which it is unlikely to be helpful and more likely to cause harm?”

He added: “A particular profile that we’re seeing increasingly at our center is someone with very active disease and onset who gets started on a high-efficacy therapy as their first therapy and effectively stops relapses and MRI lesion activity. But within a couple of years, we can tell that they’re already starting to accumulate disability. Is this someone for whom transplant might be useful, and by extension, is transplant appropriate as the first therapy in some patients? And beyond MS, is transplant a consideration for other autoimmune CNS disorders? There are lots of unanswered questions, which future studies will hopefully begin to address.”

Dr. Cohen reports consulting for Biogen, Bristol‐Myers Squibb, Convelo, EMD Serono, GlaxoSmithKline (now GSK), Janssen, Mylan, and PSI. He serves as an editor of Multiple Sclerosis Journal.

“Thankfully, once the patient ... recovers from the transplant procedure, late adverse effects are relatively uncommon, the most common of which would be infertility,” he said. “There have been some reports of successful pregnancies following transplant, but it’s important to advise people who are considering transplant that most men and women have infertility after the procedure. So if they desire to have children afterward, they need to be counseled on necessary preparations to do that.”

What about progressive multifocal leukoencephalopathy (PML), which seems a possible risk because of the suppression of the immune system? Dr. Cohen is aware of one case linked to a stem-cell transplant, and it may not have been caused by the procedure.

Cost is another potential obstacle, he noted. The National Multiple Sclerosis Society estimates that autologous hematopoietic stem cell transplants cost $150,000 on average in the U.S., although the expense varies widely.
 

Unanswered questions

Moving forward, Dr. Cohen said it remains unclear how these procedures fare against the newest generations of DMTs in MS. Five phase 3 randomized controlled trials are now trying to clarify the matter, he said, by pitting stem-cell transplantation against various MS drugs – alemtuzumab, cladribine, natalizumab, ocrelizumab, and rituximab.

There are also unanswered questions about the best conditioning regimens in the transplants, he said, and lack of clarity about where to draw the line between eligible and ineligible patients with MS. “How many DMTs does the person have to fail? What’s the upper level of disability beyond which it is unlikely to be helpful and more likely to cause harm?”

He added: “A particular profile that we’re seeing increasingly at our center is someone with very active disease and onset who gets started on a high-efficacy therapy as their first therapy and effectively stops relapses and MRI lesion activity. But within a couple of years, we can tell that they’re already starting to accumulate disability. Is this someone for whom transplant might be useful, and by extension, is transplant appropriate as the first therapy in some patients? And beyond MS, is transplant a consideration for other autoimmune CNS disorders? There are lots of unanswered questions, which future studies will hopefully begin to address.”

Dr. Cohen reports consulting for Biogen, Bristol‐Myers Squibb, Convelo, EMD Serono, GlaxoSmithKline (now GSK), Janssen, Mylan, and PSI. He serves as an editor of Multiple Sclerosis Journal.

NATIONAL HARBOR, MD. – Positive data support autologous hematopoietic stem-cell transplantation in patients with multiple sclerosis (MS), a neurologist told colleagues, and it’s a “reasonable option for people that have largely failed other disease-modifying options.” But, he said, it remains unclear which patients should undergo the procedure.

An especially pressing question is “whether transplant is an alternative to our high-efficacy disease-modifying therapies” (DMTs) in some high-risk patients, Jeffrey A. Cohen, MD, director of experimental therapeutics at Cleveland Clinic’s Mellen Center, said in a presidential lecture at the annual meeting of the Consortium of Multiple Sclerosis Centers.

A handful of ongoing randomized controlled trials will bring answers, he said.

Stem cell therapy exists because there are gaps in MS treatment, Dr. Cohen said. “We have now more than 20 medications. However, none of these therapies is completely effective in all patients. In particular, there are some patients with very active disease who continue to have relapses or new MRI lesion activity despite treatment with all of the available therapies.”

And in progressive MS, the efficacy of a couple of agents is modest and mainly for people with ongoing focal lesion activity, he said. “Finally, all of these currently available therapies are intended primarily to prevent the accumulation of damage, and none of them directly promotes repair. So despite our progress in the field, there still are a number of unmet needs.”
 

‘Rebooting’ the immune system

Several types of stem cell therapy exist, including remyelination and anti-inflammatory therapy, Dr. Cohen said. In his lecture, he focused on immunoablative or myeloablative therapy followed by autologous hematopoietic stem cell transplantation.

This “complicated, multistep procedure” involves first eliminating the immune system to get rid of pathogenic inflammatory cells. This “big component is actually the therapy for MS. It’s also the step that has the most potential complications,” he said.

According to Dr. Cohen, the next step has been described as “rebooting” the immune system.

Does this procedure help patients with MS? In relapsing MS, reports suggest there’s “almost complete abrogation of disease activity following transplant,” he said, “a benefit that’s lasted 5-10-15 years. In addition, there’s also a benefit on the accumulation of CNS damage as measured by whole brain atrophy.”

Recent data, he said, suggests that MS patients most likely to benefit are young, developed MS relatively recently, are still ambulatory, and have highly active MS despite treatment with first- and second-line agents.

However, there have only been two randomized controlled trials of stem cell transplantation versus DMT, and Dr. Cohen said both studies have limitations. The first one, from 2015, is very small, with just 21 subjects. The second study – from 2019 – is larger (n = 103), but some patients weren’t taking higher-efficacy DMTs.

Other research is more promising: Dr. Cohen highlighted a 2017 analysis that found patients with relapsing/remitting MS who underwent stem-cell transplantation were more likely to be symptom-free at 2 years (78%-83%) than those who took DMTs in clinical trials (13%-46%).
 

Clinical concerns

As for side effects of stem cell transplantation, Dr. Cohen said, “most patients have some adverse effects during the procedure itself. There may be an MS relapse or pseudorelapses in association with the mobilization and the conditioning regimens.”

A wide range of other adverse effects is possible before the immune system is reconstituted, he said, including reactivation of various virus infections, such as HPV, CMV or EPV (Epstein-Barr virus), secondary autoimmune phenomenon, and secondary malignancy. EPV infection is also common after transplant, and is “probably the most troublesome posttransplant complication from a management point of view,” he said.

“Thankfully, once the patient ... recovers from the transplant procedure, late adverse effects are relatively uncommon, the most common of which would be infertility,” he said. “There have been some reports of successful pregnancies following transplant, but it’s important to advise people who are considering transplant that most men and women have infertility after the procedure.

Patients with locally advanced rectal cancer and tumors with deficient mismatch repair (dMMR) have shown a remarkable response to treatment with the programmed cell death-1 (PD-1) inhibitor dostarlimab (Jemperli).

Thus far, the study has involved only 12 patients, but all of them have had a clinical complete response to treatment. They continue to show no signs of cancer (during follow-up ranging from 6 to 25 months) and have not undergone surgery or had radiation and chemotherapy, which are the standard treatment approaches.  

The results were presented (Abstract 16) at the American Society of Clinical Oncology annual meeting and simultaneously published in the New England Journal of Medicine.

“In our study, the elimination of tumors after 6 months of therapy with PD-1 blockade enabled us to omit both chemoradiotherapy and surgery and to proceed with observation alone,” said the authors, led by Andrea Cercek, MD, Memorial Sloan Kettering Cancer Center, New York.

About 5%-10% of patients with rectal cancer have tumors with dMMR.

“The implications for quality of life are substantial, especially among patients in whom standard treatment would affect child-bearing potential [and] given that the incidence of rectal cancer is rising among young adults of childbearing age, the use of PD-1 blockade to eliminate the need for chemoradiotherapy and surgery may confer a particular benefit in that age group,” the authors wrote.

The results of the current study are cause for “great optimism, but such an approach cannot yet supplant our current curative treatment approach,” Dr. Hanna K. Sanoff, MD, University of North Carolina at Chapel Hill, wrote in an accompanying editorial.
 

Single-agent dostarlimab

For the study, all patients were treated with single-agent dostarlimab every 3 weeks for 6 months.

Dostarlimab is already approved by the Food and Drug Administration for use in the treatment of recurrent or advanced endometrial cancer with dMMR. Rectal cancer is an off-label use.

All patients had mismatch repair-deficient stage 2 or 3 rectal adenocarcinoma. The authors noted that these tumors respond poorly to standard chemotherapy regimens, including neoadjuvant chemotherapy. The median age of enrolled patients was 54 years and 62% were women.

For the study, investigators planned that patients who had a clinical complete response after completion of dostarlimab were to proceed to observation without undergoing either chemoradiotherapy or surgery, while those who did not have a complete response were to have received these standard treatments.

As it turned out, all 12 patients achieved a complete response and have been followed by observation alone. The median follow-up from time of enrollment to data cutoff for the 12 patients was 12 months.

“Therapeutic responses were rapid,” the authors noted, “with resolution of symptoms within 8 weeks after initiation of dostarlimab in 81% of the patients.”

To date, four patients have had 1 year of sustained clinical complete response after completion of the anti-PD-1 course.

In addition to the 12 patients documented in the study, another four patients have received at least one dose of dostarlimab and continue to receive treatment.

Adverse events occurred in most patients but none were grade 3 or higher. The most common grade 1 or 2 adverse events were rash or dermatitis, pruritus, fatigue, nausea and, in one patient, thyroid-function abnormalities.

The authors speculated that in addition to the extremely high tumor mutational burden associated with mismatch-repair deficiency, a tumor cell–extrinsic factor such as the gut microbiome may be driving the exceptionally good response to PD-1 blockade seen in this patient population.
 

Editorial commentary

In the editorial, Dr. Sanoff emphasized that the approach remains experimental and should not replace current curative treatment. She noted that cancer recurrences have been seen in other studies using both chemotherapy and immunotherapy. 

For example, with chemotherapy and radiation, those patients who achieve a clinical complete response have a better prognosis compared with those who do not, but she cautioned that “cancer regrowth occurs in 20% to 30% of such patients when the cancer is managed nonoperatively.”

Dr. Sanoff noted that recurrences were seen when this approach of PD-1 inhibition has been used for metastatic colorectal cancer with dMMR. In the KEYNOTE-177 trial with pembrolizumab (Keytruda), only 55% of patients were reported to be alive without cancer progression at 12 months, and of the patients who initially had a strong response, only 70% had an ongoing response 3 years later.

“These recurrence dynamics may (or may not) differ between immunotherapy and chemoradiotherapy and between early and late-stage disease,” Dr. Sanoff said.

“In fact, very little is known about the duration of time needed to find out whether a clinical complete response to dostarlimab equates to cure,” she added.

In addition, Dr. Sanoff warned that the decision not to pursue further treatment and to follow patients with observation alone requires very close monitoring.

The current study was conducted at a top U.S. cancer center, Memorial Sloan Kettering Cancer Center. The authors noted that the complete responses (after a minimum of 6 months of follow-up) were measured by the combination of rectal MRI, visual endoscopic inspection, and digital rectal examination.

The completeness of these responses was further supported by the absence of residual tumor on serial endoscopic biopsies and the resolution of 18F-fluorodeoxyglucose uptake on PET scans, the authors added.

In the editorial, Dr. Sanoff said that “safe nonoperative management [also] involves access to specialty care for direct intraluminal visualization and expertise in interpretation of rectal magnetic resonance imaging ... Such expertise is not available in all communities and without it, patients could miss the opportunity for curative resection if tumor regrowth occurred.”

The study was sponsored by the Simon and Eve Colin Foundation, GlaxoSmithKline, and Stand Up to Cancer, among others.

A novel approach that involves sensors, artificial intelligence, and real-time individualized lifestyle guidance from an app and live coaches led to a high rate of remission of type 2 diabetes in a new study.

Specifically, among 199 patients with type 2 diabetes in India who received the app-delivered lifestyle guidance developed by Twin Health, Mountain View, Calif., mean hemoglobin A1c dropped from 9.0% to 5.7% at 6 months.

This is “huge,” Paramesh Shamanna, MD, told a press briefing at the annual scientific sessions of the American Diabetes Association. The research was presented as three posters by the group at the meeting.

Patients were a mean age of 43 and had diabetes for a mean of 3.7 years and up to 8 years.

An “unprecedented” 84% of patients had remission of diabetes at 6 months, Dr. Shamanna, medical director at Twin Health, noted.

Diabetes remission was defined according to the 2021 joint consensus statement from the ADA and other organizations as an A1c less than 6.5% without the use of diabetes medications for at least 3 months.

Importantly, patients’ time in range (percentage of time spent in target blood glucose range) increased from 53% to 81%, Dr. Shamanna pointed out. On average, patients’ waist circumference decreased by 10 cm (3.9 inches) and their weight dropped from 79 kg (approximately 174 lb) to 68 kg (150 lb).

These results are driven by “the continuous individualized and precise guidance regarding nutrition, activity, and sleep,” Dr. Shamanna said in an interview.
 

Remission is not reversal or cure ...

“Remission” from type 2 diabetes is not “reversal” or a “cure,” Robert A. Gabbay, MD, PhD, chief scientific and medical officer of the ADA, stressed to the press. Just like cancer, diabetes can return after remission

Therefore, it is important to follow the lifestyle guidance. Patients may still be at risk for diabetes complications after diabetes remission, so it’s also important to continue to be screened for eye disease, nerve damage, and lipid levels.

However, “remission can be made to last,” Dr. Shamanna said, by continuing to follow the lifestyle advice and getting back on track after a relapse.

“We’re in a different time right now,” Lisa Shah, MD, chief medical officer, Twin Health, noted. “This is very different from management of blood glucose to a certain number.”

This study shows that “remission [from type 2 diabetes] is possible. How you achieve it can be precise for you.”

The program is designed to consider the health and happiness of the patient, added Shashank R. Joshi, MD, chief scientist, Twin Health. “We want remission to be complication free. These findings give patients hope.”

“It’s exciting now that we can really start thinking about remission as an option for people with [type 2] diabetes, and that just provides such incredible hope for all of those living with [type 2] diabetes,” Dr. Gabbay said in an interview.
 

How the intervention works

The Twin Precision Treatment (TPT) intervention integrates multiple data – glucose values from a continuous glucose monitor (CGM); heart rate, activity, and sleep time from a fitness tracker; blood pressure values from a blood pressure cuff; food intake from the patient’s food log; and weight and body fat data from a smart scale – and provides the patient with precise, individualized nutrition and health guidance.

The four most critical sensors are the CGM, the fitness tracker, the smart scale, and the blood pressure cuff, Dr. Shah explained. The system gathers thousands of signals combined with patient self-reported data including mood or anxiety.

The CGM is used to build the initial nutrition guidance during the first 30 days. Once a patient is in remission, he or she can just keep the fitness tracker and smart scale.

The coaches who are part of this program include dietitians who are trained to provide compassionate patient education and help patients avoid diabetes relapse, and they are overseen by a licensed provider.

The program does not restrict calories. “It is not a diet,” Dr. Shah stressed.

The algorithm makes mini adjustments to the food a person is already eating to improve nutrition, Dr. Joshi explained. “This is personalized medicine at its best.” Patients eat food that they like and are guided to make small changes to get glucose under control and avoid glucose spikes.

The program is designed to safely deescalate diabetes medications as A1c decreases, Dr. Shamanna added.

U.S. clinical trial, health insurance coverage

The 1-year results of the current trial are expected in August, and the trial will continue for 2-=5 years, Dr. Shamanna said.

The company has started a clinical trial in the United States, with 5-year results expected in 2027.

“Currently, in the United States, we are partnering with self-insured employers and select health plans that offer [Twin Precision Treatment ] as an available benefit for their members,” Dr. Shah said. It “is suitable for most members living with type 2 diabetes, with rare exclusion situations.”

The study was funded by Twin Health. Dr. Shamanna, Dr. Shah, and Dr. Joshi are employees of Twin Health.

The coaches who are part of this program include dietitians who are trained to provide compassionate patient education and help patients avoid diabetes relapse, and they are overseen by a licensed provider.

The program does not restrict calories. “It is not a diet,” Dr. Shah stressed.

The algorithm makes mini adjustments to the food a person is already eating to improve nutrition, Dr. Joshi explained. “This is personalized medicine at its best.” Patients eat food that they like and are guided to make small changes to get glucose under control and avoid glucose spikes.

The program is designed to safely deescalate diabetes medications as A1c decreases, Dr. Shamanna added.

U.S. clinical trial, health insurance coverage

The 1-year results of the current trial are expected in August, and the trial will continue for 2-=5 years, Dr. Shamanna said.

The company has started a clinical trial in the United States, with 5-year results expected in 2027.

“Currently, in the United States, we are partnering with self-insured employers and select health plans that offer [Twin Precision Treatment ] as an available benefit for their members,” Dr. Shah said. It “is suitable for most members living with type 2 diabetes, with rare exclusion situations.”

The study was funded by Twin Health. Dr. Shamanna, Dr. Shah, and Dr. Joshi are employees of Twin Health.

A novel approach that involves sensors, artificial intelligence, and real-time individualized lifestyle guidance from an app and live coaches led to a high rate of remission of type 2 diabetes in a new study.

Specifically, among 199 patients with type 2 diabetes in India who received the app-delivered lifestyle guidance developed by Twin Health, Mountain View, Calif., mean hemoglobin A1c dropped from 9.0% to 5.7% at 6 months.

This is “huge,” Paramesh Shamanna, MD, told a press briefing at the annual scientific sessions of the American Diabetes Association. The research was presented as three posters by the group at the meeting.

Patients were a mean age of 43 and had diabetes for a mean of 3.7 years and up to 8 years.

An “unprecedented” 84% of patients had remission of diabetes at 6 months, Dr. Shamanna, medical director at Twin Health, noted.

Diabetes remission was defined according to the 2021 joint consensus statement from the ADA and other organizations as an A1c less than 6.5% without the use of diabetes medications for at least 3 months.

Importantly, patients’ time in range (percentage of time spent in target blood glucose range) increased from 53% to 81%, Dr. Shamanna pointed out. On average, patients’ waist circumference decreased by 10 cm (3.9 inches) and their weight dropped from 79 kg (approximately 174 lb) to 68 kg (150 lb).

These results are driven by “the continuous individualized and precise guidance regarding nutrition, activity, and sleep,” Dr. Shamanna said in an interview.
 

Remission is not reversal or cure ...

“Remission” from type 2 diabetes is not “reversal” or a “cure,” Robert A. Gabbay, MD, PhD, chief scientific and medical officer of the ADA, stressed to the press. Just like cancer, diabetes can return after remission

Therefore, it is important to follow the lifestyle guidance. Patients may still be at risk for diabetes complications after diabetes remission, so it’s also important to continue to be screened for eye disease, nerve damage, and lipid levels.

However, “remission can be made to last,” Dr. Shamanna said, by continuing to follow the lifestyle advice and getting back on track after a relapse.

“We’re in a different time right now,” Lisa Shah, MD, chief medical officer, Twin Health, noted. “This is very different from management of blood glucose to a certain number.”

This study shows that “remission [from type 2 diabetes] is possible. How you achieve it can be precise for you.”

The program is designed to consider the health and happiness of the patient, added Shashank R. Joshi, MD, chief scientist, Twin Health. “We want remission to be complication free. These findings give patients hope.”

“It’s exciting now that we can really start thinking about remission as an option for people with [type 2] diabetes, and that just provides such incredible hope for all of those living with [type 2] diabetes,” Dr. Gabbay said in an interview.
 

How the intervention works

The Twin Precision Treatment (TPT) intervention integrates multiple data – glucose values from a continuous glucose monitor (CGM); heart rate, activity, and sleep time from a fitness tracker; blood pressure values from a blood pressure cuff; food intake from the patient’s food log; and weight and body fat data from a smart scale – and provides the patient with precise, individualized nutrition and health guidance.

The four most critical sensors are the CGM, the fitness tracker, the smart scale, and the blood pressure cuff, Dr. Shah explained. The system gathers thousands of signals combined with patient self-reported data including mood or anxiety.

The CGM is used to build the initial nutrition guidance during the first 30 days. Once a patient is in remission, he or she can just keep the fitness tracker and smart scale.

In patients with uncontrolled gout, response rates were increased by 32% when methotrexate was used in conjunction with pegloticase versus pegloticase plus a placebo, it was reported at the annual European Congress of Rheumatology.

In the phase 4 MIRROR trial, 71% of patients who received pretreatment with methotrexate and then the combination of methotrexate and pegloticase achieved uric-acid levels lower than 6 mg/dL for more than 80% of the time during weeks 20-24 of the 52-week study. By comparison, only 39% of those treated with pegloticase plus a placebo achieved this primary endpoint (P < .0001).

This is good news for patients, suggested two rheumatologists who were not involved in the study. The combination appears “useful for a select group of gout patients,” observed Christian Ammitzbøll, MD, PhD, from Aarhus University Hospital, Denmark.

“Very promising in refractory gout,” agreed Emre Bilgin, MD, from Ankara, Turkey.
 

Rationale for using methotrexate

“Oral urate lowering agents are the mainstay of treatment of gout, but there are patients that just don’t respond to oral agents,” said Dr. Botson, a rheumatologist in private practice from Anchorage, Alaska.

“These patients are very difficult to treat,” he added. “They have a lot of physical disabilities, they have high medical comorbidities, and they have a low quality of life. Their treatment options are extremely limited.”

One of the few options they have is pegloticase, a pegylated uric acid specific enzyme sold under the brand name Krystexxa for the past 12 years. It lowers serum uric acid by converting it to allantoin, which is more water soluble and thus is easier to excrete from the body.

However, one of the problems of using the drug is that anti-drug antibodies frequently develop, meaning that discontinuation rates can be as high as 50%, with around a quarter of patients at high risk of experiencing an infusion reaction.

“Methotrexate is a medication we’re very familiar with for other rheumatologic conditions that use biologic medications, and we use this to prevent anti-drug antibodies. So, the MIRROR RCT was a study we performed to examine the pegloticase therapy in combination with methotrexate co therapy,” explained Dr. Botson.

In fact, co-administration of methotrexate and pegloticase was associated with fewer infusion reactions than using pegloticase alone (3% vs. 31%).
 

Study design and results

A total of 152 patients were included in the trial and were treated with methotrexate at a weekly dose of 15 mg for 2 weeks before being randomized, 2:1, to either continue methotrexate and then receive intravenous pegloticase or receive the latter with a placebo. Pegloticase was given at a dose of 8 mg every 2 weeks. Treatment was for 52 weeks, with the primary endpoint of serum uric acid response tested at 6 months.

The reason for the 2-week run-in period with methotrexate was to check that patients would be able to tolerate it, Dr. Botson explained.

The mean age of patients was around 54 years, the majority (> 84%) were male and were White (69%). The average duration of gout was about 14 years, with over 74% having tophi present at screening and experiencing 10-11 flares in the previous year. Baseline serum uric acid averaged at about 9 mg/dL.

Almost three-quarters of the 100 patients (73%) who were treated with the combination completed treatment to week 24 while the corresponding percentage in the placebo arm (n = 52) was 39%. The main reason for stopping was due to lack of efficacy (27% and 61% of cases, respectively), defined as having serum uric acid levels above 6 mg/dL on two consecutive measurements.

The median time to discontinuation was 69 days for those in the placebo arm; “it was non-estimable” in the methotrexate arm, Dr. Botson reported.

The mean change in serum uric acid through to week 24 was higher in the methotrexate than placebo arm, at a respective 7.66 and 5.23 mg/dL, giving a significant mean difference of 2.43 mg/dL.

There was a “dramatic resolution of tophaceous deposits,” Dr. Botson said. Complete resolution of tophi was seen in 34.6% of methotrexate-treated patients versus 13.8% of pegloticase-placebo–treated patients (P = .043).

One of the most common adverse events associated with pegloticase treatment is gout flare, which occurred in about 70% of participants in both study arms. Overall, the addition of methotrexate did not increase the risk for adverse events in general, and of the two deaths seen in the study – both in methotrexate-treated patients – one was because of a heart attack and another due COVID-19, so they were unrelated to study treatment.

In patients with renal insufficiency

Concern was raised during the discussion, however, on how to handle methotrexate use in patients with renal insufficiency.

“That’s been a debate that we’ve had in this study and others,” said Dr. Botson, acknowledging that “methotrexate is often a concern for the nephrologist that we’re co-treating these patients with.” However, no dose adjustments were needed in the study.

“There are some other studies with other immunomodulators that do suggest that other agents could be used that may be a little less potentially renal toxic, but we didn’t see any toxicity in the patients that we had, even in those that had a reduced [glomerular filtration rate],” he added.

Dr. Botson has received research support from Horizon and Radius Health. He also acknowledged receiving speakers fees from AbbVie, Amgen, Aurinia, ChemoCentryx*, Horizon, Eli Lilly, and Novartis.
