Psoriatic Arthritis

Key clinical point: Ustekinumab and a tumor necrosis factor inhibitor (TNFi) showed comparable efficacy, safety, and drug persistence after 1 year of treatment in real-world patients with psoriatic arthritis (PsA).

Major finding: After 1 year of treatment, ustekinumab vs. TNFi showed similar persistence (hazard ratio for stopping/switching treatment 0.82; 95% CI 0.60-1.13) and a similar proportion of patients achieving clinical low disease activity  on the Disease Activity Index for PsA  (odds ratio [OR] 0.80; 95% CI 0.57-1.10) and remission (OR 0.73; 95% CI 0.49-1.07), along with a similar safety profile.

Study details: Findings are from a 1-year analysis of the prospective, observational PsABio study including 893 patients with PsA who were prescribed first-line to third-line ustekinumab or TNFis.

Disclosures: PsABio study was sponsored by Janssen. The authors declared receiving grants, personal fees, consulting fees, research support, nonfinancial support, and honoraria from several sources, including Janssen. Three authors declared being employees or shareholders of Janssen or Johnson and Johnson, Janssen’s corporate parent.

Key clinical point: Methotrexate+leflunomide therapy was superior to methotrexate monotherapy at improving disease activity in patients with psoriatic arthritis (PsA); however methotrexate+leflunomide therapy was less well tolerated than methotrexate monotherapy.

Major finding: At week 16, PsA disease activity score improved significantly in the methotrexate+leflunomide vs. methotrexate monotherapy group (3.1 vs. 3.7; P = .025). Incidence of mild adverse events, such as nausea/vomiting (44% vs. 28%) and altered bowel habits (26% vs. 8%), was higher with methotrexate+leflunomide vs. methotrexate+placebo.

Study details: Findings are from the phase 3 COMPLETE-PsA trial including 78 patients with active PsA who were randomly assigned to receive 2 tablets/day of 10 mg leflunomide or placebo once/day, both with 25 mg/week methotrexate.

Key clinical point: Findings from the CONTROL trial support adding adalimumab over escalating methotrexate in patients with psoriatic arthritis (PsA) who respond inadequately to the initial methotrexate dose.

Major finding: At week 16, a significantly higher proportion of patients achieved minimal disease activity after adding adalimumab to methotrexate vs. escalating methotrexate dose (41% vs. 13%; P < .0001), with the efficacy being maintained through 32 weeks by 80% of adalimumab responders despite methotrexate withdrawal at 16 weeks. No new safety signals were identified.

Study details: Findings are from the phase 4 CONTROL trial including 245 patients with active PsA with an inadequate response to methotrexate. They were randomly assigned to receive 15 mg/week adalimumab+methotrexate or have a methotrexate dose escalated up to 25 mg/week for 16 weeks; responders either maintained or modified their current therapy and nonresponders had their therapy escalated until 32 weeks.

Disclosures: This study was funded by AbbVie. Four authors declared being employees or stockholders of AbbVie and other authors reported ties with various sources including AbbVie.

For patients with psoriatic arthritis (PsA) whose condition doesn’t respond adequately to methotrexate, addition of the tumor necrosis factor (TNF) inhibitor adalimumab increased the likelihood of achieving minimum disease activity (MDA), compared with escalation of MTX dose, according to results from a phase 4, open-label study.

The new study is one of only a few to compare treatment protocols in a field that has seen new therapeutic options become available in recent years. That lack of evidence can leave patients and physicians uncertain about the next step if the initial results of treatment are disappointing.

“There are some gaps in our database and our understanding of psoriatic arthritis, compared to rheumatoid arthritis, where we have had many more studies over the years,” Arthur Kavanaugh, MD, told this news organization when asked to comment on the study.

The trial provides one answer, at least. “There was a clear-cut signal that it made more sense to add adalimumab at that early juncture where a person is not quite doing well enough on methotrexate to satisfy our goal of getting the patient to low disease activity. It gives us as clinicians some ammunition to speak to our insurance formulary people on this side of the Atlantic, or [for] people in the U.K. to go to their local regulatory board that approves medicines and be able to show them some actual practically derived evidence about this very common question that comes up in practice,” senior and corresponding author Philip Mease, MD, said in an interview. The study was published online in The Lancet Rheumatology.

“When a clinician and patient are making the decision to move on from methotrexate monotherapy, either because of lack of efficacy or safety issues, tolerability issues, it makes most sense to add on a biologic medication such as a TNF inhibitor at that juncture, rather than intensifying methotrexate therapy,” said Dr. Mease, who is director of rheumatology research at Swedish Medical Center/Providence St. Joseph Health and a clinical professor at the University of Washington, both in Seattle.

Physicians may be tempted to bump up the dose for patients who can tolerate MTX and who may be showing some improvement, but the new study should prompt a different strategy if MDA isn’t achieved, according to Oliver FitzGerald, MD, a professor at the Conway Institute for Biomolecular Research at University College Dublin, who was asked to comment on the study. “This study clearly shows that the early addition of adalimumab is the better choice, and it would change practice. That being said, there are clearly some patients who do respond sufficiently to increasing methotrexate, and it would be useful to be able to predict which patients might do that.” He added that the study focused on adalimumab and that the results might not apply to other biologics.

The study should encourage use of a quantitative treat-to-target measure like MDA, which is a composite measure of patient perspectives, Dr. Mease said. The American College of Rheumatology and National Psoriasis Foundation and Group for Research and Assessment of Psoriasis and Psoriatic Arthritis have recommended the use of MDA as a treat-to-target measure for PsA. The ACR and NPF recommend TNF inhibitors as first-line treatment, and GRAPPA includes it as a first-line option, whereas the European Alliance of Associations for Rheumatology recommends MTX only in the first line.

The study also suggests that there is value to using adalimumab on a weekly basis if an every-other-week schedule doesn’t produce the desired results. This strategy hasn’t been examined in PsA or even RA, according to Dr. Kavanaugh, who is a professor of medicine at the University of California, San Diego. “It did look like raising the dose might be an option for patients who are on every other week and are not doing quite as well as we would have hoped.”

The CONTROL study was a phase 4, two-part, open-label study. It included 245 patients in 14 countries who did not have MDA with MTX. In the first part of the study, patients were randomly assigned to receive weekly 15 mg MTX along with 40 mg adalimumab every other week, or escalation of MTX dose to 20-25 mg/week. MTX could be administered orally or intravenously. After 16 weeks (part 1), for patients who achieved MDA, current therapy was maintained or modified; for patients who did not achieve MDA, therapy was escalated over the following 16 weeks by giving adalimumab every week in the combination group or by adding adalimumab every other week in the MTX escalation arm.

Overall, 95% of the MTX plus adalimumab group completed part 1, as did 90% of the MTX escalation group. A total of 41% of the adalimumab group achieved MDA at 16 weeks versus 13% of the MTX group (P < .0001). The result held after accounting for sex and the interaction between sex and treatment (odds ratio, 4.6; 95% confidence interval, 2.4-8.9).

Among patients who achieved MDA at 16 weeks, 80% in the adalimumab group continued to have MDA at 32 weeks even after MTX had been withdrawn. Of those in the MTX escalation group, 67% continued to have MDA at 32 weeks with continued escalation of MTX.

Of the patients in the MTX escalation group who did not respond, 55% reached MDA following introduction of adalimumab every other week. Of those who did not respond to adalimumab, 30% reached MDA after switching to weekly adalimumab doses.

The study was open label, and patients who received adalimumab may have expected some improvement; that could have skewed the findings, Dr. Kavanaugh said. “I think that’s an important consideration as we interpret the data. The people who got the MTX arm probably had less of an expectation that they were going to do much better than those who switched to the adalimumab, as did the doctors taking care of them.”

The CONTROL study was funded by AbbVie. Dr. Mease has received research grants, consulted for, or received speaker honoraria from AbbVie, Amgen, Bristol-Myers Squibb, Boehringer Ingelheim, Celgene, Galapagos, Gilead, Janssen, Lilly, Novartis, Pfizer, Sun Pharma, and UCB. Dr. FitzGerald has received grant support and honoraria from AbbVie. Dr. Kavanaugh has received research support from or consulted for AbbVie, Janssen, Pfizer, Lilly, Novartis, and UCB.

Exposure to air pollution – even short term – may play a role in triggering psoriasis flares, according to new research from Italy, which found a significant association between exposure to higher levels of air pollution prior to patients presenting for psoriasis flares at medical visits, compared with visits unrelated to flares.

“We found that higher concentration of different air pollutants was associated with psoriasis flares in patients living in an industrialized city of the Po Valley” in Verona, Italy, report the authors of the study, published in JAMA Dermatology.

The findings underscore the need for clinicians to “consider environmental/external triggers in patients with chronic inflammatory diseases experiencing flares,” first author Francesco Bellinato, MD, of the Section of Dermatology and Venereology, University of Verona, Italy, told this news organization.

He and his coauthors conducted a case-crossover and cross-sectional longitudinal study that involved a retrospective analysis of data in 957 patients in Verona with chronic plaque psoriasis, who were evaluated every 3-4 months at an outpatient dermatology clinic for a median of 2.7 years.

Over the study period, disease flares, defined as an increase in the Psoriasis Area and Severity Index (PASI) of 5 or more points from the previous visit, occurred in 369 patients (38.6%), consistent with known flare rates in psoriasis. Participants in the study (mean age, 61) had median PASI scores of 12 during visits for psoriatic flares compared with PASI scores of 1 during control (no flare) visits (P < .001).

Evaluations of mean concentrations of several air pollutants within 10 miles of the patients over 4,398 visits showed that concentrations were significantly higher in the 60 days prior to the psoriasis flare, compared with control visits that were not related to flares (P < .05), after adjusting for factors including seasonality (by trimester, to adjust for weather conditions and UV/sunlight exposure) and the type of systemic psoriasis treatments patients were receiving (conventional or biological).

Increases in air pollutant levels prior to flares were observed among the 35.8% of patients who had a flare of at least a 50% increase in the PASI score, as well among the 47.2% of patients who had at least a 100% increase in PASI, compared with control visits not involving flares. In addition, mean and area-under-the-curve concentrations of air pollutants were higher in the 60 days before the visits among those with PASI 5 or greater, compared with those with PASI scores below 5, the authors add.

Dr. Bellinato noted that the associations were not limited to any particular subgroup. “The associations with air pollution and flares were observed in the entire population,” he said in an interview.

Vehicle, industry emissions

The pollutants that were measured were those mainly associated with fossil fuel combustion from vehicle and industry emissions, including carbon monoxide, nitrogen dioxide, other nitrogen oxides, benzene, coarse particulate matter (2.5-10.0 μm in diameter) and fine particulate matter (less than 2.5 μm in diameter).

They note that the risk of having a PASI score of 5 or greater was elevated even at thresholds of exposure that are largely considered safe. “Indeed, the risk for having a PASI score of 5 or greater was 40% to 50% higher at exposures as low as 20 μg/m³” of coarse particulate matter and 15 μg/m³ of fine particulate matter in the 60-day period prior to the visits, they write.

The authors referred to evidence linking air pollution with a worsening of a variety of inflammatory cutaneous diseases, including atopic dermatitis and acne, as well as photoaging. Psoriasis flares are known to be triggered by a variety of environmental factors, including infections or certain drugs; however, evidence of a role of air pollution has been lacking. Potential mechanisms linking the exposures to flares include the possibility that exhaust particles can activate skin resident T-cells, “resulting in abnormal production of proinflammatory cytokines including tumor necrosis factor α (TNF-α) and interleukins (ILs), including IL-1α, IL-1β, IL-6, and IL-8.8,” the authors write.

Their results, though inferring a causal relationship, fall short of showing a clear dose–response relationship between higher pollutant levels and an increased risk of psoriasis flares, possibly the result of a smaller sample size of subjects exposed to higher levels of pollution, they add.

Limitations of the study included the definition of flare, which used a clinical score that could be affected by other measurements, they point out, while strengths of the study included the large cohort of patients followed for over 7 years and the availability of daily measurements of air pollutants.

While the study suggests that environmental air pollutant fluctuations may affect psoriasis course,” the authors concluded, “further study is needed to examine whether these findings generalize to other populations and to better understand the mechanisms by which air pollution may affect psoriasis disease activity.”

Dr. Bellinato and four coauthors had no disclosures; the remaining authors had disclosures that included receiving personal fees from pharmaceutical companies that were outside of the submitted work.

The risk of cardiovascular (CV) events in patients with psoriatic disease rises with higher levels of two cardiac biomarkers in a manner independent of risk calculated by the Framingham Risk Score (FRS), a longitudinal cohort study has shown. But researchers who conducted the study note that neither of the two biomarkers identified in the study – cardiac troponin I (cTnI) and N-terminal pro-brain-type natriuretic peptide (NT-proBNP) – led to an improvement in predictive performance when combined with the FRS, despite their association with carotid plaque burden.

Psoriasis and psoriatic arthritis are both associated with greater risk of CV morbidity and mortality, partly because of systemic inflammation that leads to atherogenesis. Measures of CV risk such as the FRS rely on traditional measures of CV risk and thus are likely to underestimate the CV event risk of people with psoriatic disease, according to the authors of the new study, published online in Arthritis & Rheumatology. The effort was led by Keith Colaço, MSc; Lihi Eder, MD, PhD; and other researchers affiliated with the University of Toronto.

“We are desperately in need of biomarker science advancement in psoriatic arthritis for a variety of places of guidance: How to choose a medication more accurately for the patient in front of us – that is, getting to be more like oncologists who use biomarkers to pick the best treatment or combination. That’s an important need. A second important need is how to guide clinicians regarding risk prediction for things like persistent, severe disease activity, progressive structural damage from disease, and, in this case, predicting a very common comorbidity that occurs in [psoriasis and] psoriatic arthritis patients,” Philip J. Mease, MD, told this news organization when asked to comment on the study.

Such biomarkers could assist with patient counseling, according to Dr. Mease, who is director of rheumatology research at Swedish Medical Center/Providence St. Joseph Health and is a clinical professor at the University of Washington, both in Seattle. Some patients may struggle with advice to lose weight or adopt lifestyle measures to limit CV risk, and more accurate predictions of risk may serve as further motivation. “It could well be that if you have a biomarker that accurately predicts a coming cataclysm, that it will lead you to redouble your efforts to do whatever it takes to reduce cardiovascular risk,” he said.

Both cTnI and NT-proBNP have been linked to increased CV risk in the general population, but little work has been done in the context of rheumatologic diseases.

The researchers analyzed data from 358 patients seen at the University of Toronto. The mean follow-up was 3.69 years. After adjustment for CV risk factors, lipid-lowering therapy, and creatinine levels, there was an association between cTnI levels and total carotid plaque area (adjusted beta coefficient, 0.21; 95% confidence interval, 0-0.41), but not for levels of NT-proBNP.

Atherosclerosis progressed in 89 participants overall, but multivariate adjustment revealed no significant relationship between progression and cTnI or NT-proBNP levels.

Separately, the researchers analyzed 1,000 individuals with psoriatic arthritis (n = 648) or with psoriasis and no arthritis (n = 352) whom they followed for a mean of 7.1 years after the patients underwent evaluation during 2002-2019. After adjustment for FRS, there was an association between the risk of a CV event and each 1–standard deviation increase in both cTnI (hazard ratio, 3.02; 95% CI, 1.12-8.16) and NT-proBNP (HR, 2.02; 95% CI, 1.28-3.18).

The combination of both biomarkers with the FRS predicted higher CV risk (HR, 1.91; 95% CI, 1.23-2.97). Neither biomarker made a statistically significant difference in changing CV risk prediction when added individually to FRS, although cTnI trended toward significance (HR, 2.60; 95% CI, 0.98-6.87).

Instead of the carotid plaque burden, Dr. Mease would have liked to have seen the authors evaluate calcium scores in coronary arteries as measured by CT. “I would have loved to have seen the researchers using that in addition to the carotid plaque assessment, to see what that would show us about these patients,” he said.

Only a small number of patients experienced CV events during the study period, which will likely make it necessary to conduct larger studies to identify a clear relationship. “You need a registry-type study with probably many hundreds if not thousands of patients in order to identify whether or not adding troponin could be useful to what we typically measure with patients when we’re trying to assess their risk,” Dr. Mease said.

The study was supported in part by the National Psoriasis Foundation and the Arthritis Society. Individual researchers have received support from a range of sources, including the Enid Walker Estate, the Women’s College Research Institute, the Arthritis Society, the National Psoriasis Foundation, the Edward Dunlop Foundation, the Ontario Ministry of Science and Innovation, and a Pfizer Chair Research Award. Some of the researchers have financial relationships with pharmaceutical companies that market drugs for psoriasis and psoriatic arthritis.

Survival rates of biologics and other novel immunomodulatory drugs vary substantially across chronic inflammatory diseases, and rates are highest for rituximab in rheumatoid arthritis (RA) and golimumab in axial spondyloarthritis (axSpA), but with similar rates seen for most drugs used in the treatment of psoriasis and psoriatic arthritis (PsA), according to findings from a study of two Danish registries.

Drug survival refers to “the probability that patients will remain on a given drug, and is a proxy for efficacy as well as safety in daily clinical practice,” wrote Alexander Egeberg, MD, PhD, of the department of dermatology at Copenhagen University Hospital–Bispebjerg, and colleagues. Although the use of biologics has expanded for inflammatory diseases, real-world data on drug survival in newer agents such as interleukin (IL)-17, IL-23, and Janus kinase inhibitors are lacking, they said.

In a study published in Seminars in Arthritis and Rheumatism, the researchers reviewed data from the DANBIO and DERMBIO registries of patients in Denmark with inflammatory diseases including rheumatoid arthritis (RA), axial spondyloarthritis (AxSpA), psoriatic arthritis (PsA), and psoriasis.

The study population included 12,089 adults: 5,104 with RA, 2,157 with AxSpA, 2,251 with PsA, and 2,577 with psoriasis. Patients’ mean age at the time of first treatment for these conditions was 57.8 years, 42.3 years, 49 years, and 45 years, respectively. Participants were treated with biologics or novel small molecule therapies for RA, AxSpA, PsA, or psoriasis between January 2015 and May 2021 (from the DANBIO database) and November 2009 to November 2019 (DERMBIO database).

In adjusted models, drug survival in RA was highest for rituximab followed by baricitinib, etanercept, and tocilizumab. Drug survival in AxSpA was highest for golimumab, compared with all other drugs, followed by secukinumab and etanercept. Survival was lowest for infliximab. In PsA, drug survival was roughly equal for most drugs, including golimumab, secukinumab, and ixekizumab, with the lowest survival observed for tofacitinib and infliximab, compared with all other drugs. Drug survival in psoriasis was highest with guselkumab, followed by ustekinumab and IL-17 inhibitors.

However, the number of treatment series “was low for some drugs, and not all differences were statistically significant, which could influence the overall interpretability of these findings,” the researchers noted in their discussion.

Notably, the high treatment persistence for rituximab in RA patients needs further confirmation, the researchers said. “In Denmark, rituximab is often the biologic drug of choice in RA patients with a history of cancer while there is a reluctancy to use TNF [tumor necrosis factor] inhibitors in such patients; this may have prolonged the drug survival for rituximab treated patients due to limited treatment alternatives,” they said.

The findings were limited by several factors, including the observational study design and changes in guidelines over the course of the study, the researchers noted. Other limitations included the inability to adjust for certain variables, such as antibody status, body weight, and smoking, because of missing data, and a lack of data on the underlying reasons for drug discontinuation, they said.

However, the results were strengthened by the large number of patients and completeness of the registries, the researchers emphasized. The range in responses to different drug types across diseases supports the need for individualized treatments with attention to underlying disease, patient profile, and treatment history, they concluded.

The study received no outside funding. Eight coauthors reported financial ties to a number of pharmaceutical companies.

In a study published in Seminars in Arthritis and Rheumatism, the researchers reviewed data from the DANBIO and DERMBIO registries of patients in Denmark with inflammatory diseases including rheumatoid arthritis (RA), axial spondyloarthritis (AxSpA), psoriatic arthritis (PsA), and psoriasis.

The study population included 12,089 adults: 5,104 with RA, 2,157 with AxSpA, 2,251 with PsA, and 2,577 with psoriasis. Patients’ mean age at the time of first treatment for these conditions was 57.8 years, 42.3 years, 49 years, and 45 years, respectively. Participants were treated with biologics or novel small molecule therapies for RA, AxSpA, PsA, or psoriasis between January 2015 and May 2021 (from the DANBIO database) and November 2009 to November 2019 (DERMBIO database).

In adjusted models, drug survival in RA was highest for rituximab followed by baricitinib, etanercept, and tocilizumab. Drug survival in AxSpA was highest for golimumab, compared with all other drugs, followed by secukinumab and etanercept. Survival was lowest for infliximab. In PsA, drug survival was roughly equal for most drugs, including golimumab, secukinumab, and ixekizumab, with the lowest survival observed for tofacitinib and infliximab, compared with all other drugs. Drug survival in psoriasis was highest with guselkumab, followed by ustekinumab and IL-17 inhibitors.

However, the number of treatment series “was low for some drugs, and not all differences were statistically significant, which could influence the overall interpretability of these findings,” the researchers noted in their discussion.

Notably, the high treatment persistence for rituximab in RA patients needs further confirmation, the researchers said. “In Denmark, rituximab is often the biologic drug of choice in RA patients with a history of cancer while there is a reluctancy to use TNF [tumor necrosis factor] inhibitors in such patients; this may have prolonged the drug survival for rituximab treated patients due to limited treatment alternatives,” they said.

The findings were limited by several factors, including the observational study design and changes in guidelines over the course of the study, the researchers noted. Other limitations included the inability to adjust for certain variables, such as antibody status, body weight, and smoking, because of missing data, and a lack of data on the underlying reasons for drug discontinuation, they said.

However, the results were strengthened by the large number of patients and completeness of the registries, the researchers emphasized. The range in responses to different drug types across diseases supports the need for individualized treatments with attention to underlying disease, patient profile, and treatment history, they concluded.

The study received no outside funding. Eight coauthors reported financial ties to a number of pharmaceutical companies.

Survival rates of biologics and other novel immunomodulatory drugs vary substantially across chronic inflammatory diseases, and rates are highest for rituximab in rheumatoid arthritis (RA) and golimumab in axial spondyloarthritis (axSpA), but with similar rates seen for most drugs used in the treatment of psoriasis and psoriatic arthritis (PsA), according to findings from a study of two Danish registries.

Although psoriatic arthritis is not the only disease associated with dactylitis — other culprits are sarcoidosis, septic arthritis, tuberculosis, and gout — dactylitis is one of the characteristic symptoms of psoriatic arthritis. Dactylitis is seen in as many as 35% of patients with psoriatic disease. Dactylitis clinically presents — as in this patient — with sausage-like swelling of the digits. It is included in the Classification Criteria for Psoriatic Arthritis (CASPAR) as one of the hallmarks of psoriatic arthritis. 

Dactylitis has been thought to be a result of the concomitant swelling and inflammation of the flexor tendon sheaths of the metacarpophalangeal, metatarsophalangeal, or interphalangeal joints. Flexor tenosynovitis can be detected by examination with MRI and ultrasound. Dactylitis is associated with radiologically evident erosive damage to the joints.

Patients with psoriatic arthritis are typically seronegative for rheumatoid factor and antinuclear antibody; antinuclear antibody titers in persons with psoriatic arthritis do not differ from those of age- and sex-matched controls. C-reactive protein may be elevated but is often normal. Lack of C-reactive protein elevation, however, does not mean that systemic inflammation is absent, but rather indicates that different markers are needed that allow better quantification of systemic inflammation in psoriasis and psoriatic arthritis.

Fundamental changes in the initial pharmacologic approach to psoriatic arthritis were made in the 2018 American College Rheumatology/National Psoriasis (ACR/NPF) guidelines for the treatment of psoriatic arthritis. Previously, methotrexate had been widely used as the first-line agent. The 2018 guidelines recommend a tumor necrosis factor (TNF) inhibitor over methotrexate and other oral small molecules (leflunomide, cyclosporine, and apremilast). 

Herein is a broad summary of the guidelines:

·    Treat with TNF inhibitor over oral small molecule; may consider oral small molecule with mild psoriatic arthritis and psoriasis, patient preference, and/or contraindication to TNF inhibitor
·    Treat with TNF inhibitor over interleukin (IL)-17 inhibitor; may consider IL-17 inhibitor with severe psoriasis or contraindication to TNF inhibitor
·    Treat with TNF inhibitor over interleukin (IL)-12/23 inhibitor; may consider IL-12/23 inhibitor with severe psoriasis or contraindication to TNF inhibitor
·    Treat with oral small molecule over IL-17 inhibitor; may consider IL-17 inhibitor with severe psoriasis and/or psoriatic arthritis
·    Treat with oral small molecule over IL-12/23 inhibitor; may consider IL-12/23 inhibitor with severe psoriasis or psoriatic arthritis, or concomitant inflammatory bowel disease
·    Treat with methotrexate over nonsteroidal anti-inflammatory drugs; may consider nonsteroidals for mild psoriatic arthritis and psoriasis
·    Treat with IL-17 inhibitor over IL-12/23 inhibitor; may consider IL-12/23 inhibitor in a patient with concomitant inflammatory bowel disease

Note that these recommendations are based on conditional evidence (ie, low to very low quality). In fact, in the entire guideline document, only 6% of the recommendations are strong, whereas 96% are conditional. This emphasizes the importance of evaluating each patient individually and engaging in a discussion to choose optimal therapy.

Another set of guidelines, from the Group for Research and Assessment of Psoriasis and Psoriatic Arthritis (GRAPPA), was last updated in 2015. Since then, many of the agents above have been introduced. Updated GRAPPA guidelines are expected to be released later this year.

A new study has found that methotrexate plus leflunomide outperforms methotrexate alone as a treatment option for patients with psoriatic arthritis (PsA).

“We believe that prescribing this combination in routine practice is viable when combined with shared decision-making and strict monitoring of side effects,” write Michelle L.M. Mulder, MD, of the department of rheumatology at Sint Maartenskliniek in Nijmegen, the Netherlands, and her coauthors. Their findings were published in The Lancet Rheumatology.

The latest treatment guidelines from the Group for Research and Assessment of Psoriasis and Psoriatic Arthritis and the European Alliance of Associations for Rheumatology recommend conventional synthetic disease-modifying antirheumatic drugs for patients with active PsA, but Dr. Mulder and her colleagues note a distinct lack of information on their effectiveness, especially this particular combination.

To assess the efficacy and safety of methotrexate plus leflunomide, they launched a single-center, double-blind, randomized trial that included 78 Dutch patients with PsA. The majority of the participants in this trial – dubbed COMPLETE-PsA – were men (64%), and the median age of the patients was 55 years. All had active disease at baseline; the median swollen joint count (SJC) and tender joint count were 4.0 in both groups.

Participants were assigned to receive either methotrexate plus leflunomide (n = 39) or methotrexate plus placebo (n = 39). After 16 weeks, mean Psoriatic Arthritis Disease Activity Score (PASDAS) had improved for patients in the combination therapy group in comparison with the monotherapy group (3.1; standard deviation, 1.4 vs. 3.7; SD, 1.3; treatment difference, –0.6; 90% confidence interval, –1.0 to –0.1; P = .025). The combination therapy group also achieved PASDAS low disease activity at a higher rate (59%) than did the monotherapy group (34%; P = .019).

Other notable differences after 16 weeks included improvements in SJC for 66 joints (–3.0 in the combination therapy group vs. –2.0 in the monotherapy group) and significantly better skin and nail measures – such as active psoriasis and change in body surface area – in the methotrexate plus leflunomide group.

When asked who should be prescribed the combination therapy and who should be prescribed methotrexate going forward, Dr. Mulder told this news organization, “At the moment, we have insufficient knowledge on who will benefit most or who will develop clinically relevant side effects. It seems warranted to discuss with every patient which approach they would prefer. This could be a step-down or -up approach.

“We hope to be able to better predict treatment response and side effects in the future via post hoc analysis of our study and via extensive flow-cytometric phenotyping of immune blood cells taken at baseline,” she added.

Three patients in the combination therapy group experienced serious adverse events, two of which were deemed unrelated to leflunomide. The most frequently occurring adverse events were nausea or vomiting, tiredness, and elevated alanine aminotransferase. Mild adverse events were more common in the methotrexate plus leflunomide group. No participants died, and all patients with adverse events recovered completely.

“It appears good practice to do blood draws for laboratory tests on liver enzymes at least monthly for the first 4 months and every 4 months after that once stable dosing is achieved, as well as have a telephone consultation after 6-8 weeks to talk about possible side effects a patient might experience and change or add therapy if necessary,” Dr. Mulder added.

Study turns perception of combination therapy into reality

It had already been perceived by rheumatologists that methotrexate plus leflunomide was an effective combo for PsA, and this study reinforces those beliefs, Clementina López-Medina, MD, PhD, and colleagues from the University of Cordoba (Spain), write in an accompanying editorial.

They highlight this study’s notable strengths, one of which was defining “active disease” as two or more swollen joints, which opened the study up to a larger patient population. The editorialists also underline the confirmation that leflunomide plus methotrexate reduces both joint symptoms and skin involvement in this subset of patients, which had also been found in a previous study.

“Leflunomide is usually considered as a second-line option after methotrexate is unsuccessful,” they note, “despite the fact that methotrexate did not show superiority over placebo in previous trials.”

The editorialists were not surprised that the combination therapy was more toxic than the monotherapy. Rheumatologists could use these data to individualize treatment accordingly, they write, while keeping an eye on “gastrointestinal disturbances.”

Overall, Dr. López-Medina and colleagues say that the study results should “be considered not only in daily clinical practice but also in the development of future recommendations.”

Leflunomide: Forgotten no longer, at least for PsA

“I think we probably underutilize leflunomide,” Arthur Kavanaugh, MD, professor of medicine and director of the Center for Innovative Therapy at the University of California, San Diego, told this news organization. “Sometimes medicines get ‘old,’ for lack of a better term, and fall a little bit of out of favor, sometimes unnecessarily. Leflunomide falls into that category. Because it’s older, it doesn’t get as much buzz as what’s new and shiny.

“I was not surprised by the results on the joints,” he said, “because we know from previous studies that leflunomide works in that regard. What did surprise me is that the skin got better, especially with the combination.”

Regarding the side effects for the combination therapy, he commended the authors for limiting potential uncertainty by using such a high dose of methotrexate.

“By going with a dose of 25 mg [per week], no one can say, ‘They pulled their punches and methotrexate monotherapy would’ve been just as good if it was given at a higher dose,’ “ he said. “And they also used leflunomide at a high dose. It makes you wonder: Could you use lower doses, and do lower doses mean fewer lab test abnormalities? This positive study does lend itself to some other permutations in terms of study design.

“Even though this was a small study,” he added, “it brings us right back to: We should really consider leflunomide in the treatment of PsA.”

The authors acknowledge their study’s limitations, including the fact that it was conducted in a single country and the absence of a nontreatment placebo group. They also note the higher percentage of women in the methotrexate plus leflunomide group, “which might have lowered the treatment response and increased the adverse event rate, resulting in bias.”

The study was funded by a Regional Junior Researcher Grant from Sint Maartenskliniek. The authors reported numerous potential conflicts of interest, including receiving payment, research grants, and consulting and speaker fees from various pharmaceutical companies.

The combination therapy group also achieved PASDAS low disease activity at a higher rate (59%) than did the monotherapy group (34%; P = .019).

Other notable differences after 16 weeks included improvements in SJC for 66 joints (–3.0 in the combination therapy group vs. –2.0 in the monotherapy group) and significantly better skin and nail measures – such as active psoriasis and change in body surface area – in the methotrexate plus leflunomide group.

When asked who should be prescribed the combination therapy and who should be prescribed methotrexate going forward, Dr. Mulder told this news organization, “At the moment, we have insufficient knowledge on who will benefit most or who will develop clinically relevant side effects. It seems warranted to discuss with every patient which approach they would prefer. This could be a step-down or -up approach.

“We hope to be able to better predict treatment response and side effects in the future via post hoc analysis of our study and via extensive flow-cytometric phenotyping of immune blood cells taken at baseline,” she added.

Three patients in the combination therapy group experienced serious adverse events, two of which were deemed unrelated to leflunomide. The most frequently occurring adverse events were nausea or vomiting, tiredness, and elevated alanine aminotransferase. Mild adverse events were more common in the methotrexate plus leflunomide group. No participants died, and all patients with adverse events recovered completely.

“It appears good practice to do blood draws for laboratory tests on liver enzymes at least monthly for the first 4 months and every 4 months after that once stable dosing is achieved, as well as have a telephone consultation after 6-8 weeks to talk about possible side effects a patient might experience and change or add therapy if necessary,” Dr. Mulder added.

Study turns perception of combination therapy into reality

It had already been perceived by rheumatologists that methotrexate plus leflunomide was an effective combo for PsA, and this study reinforces those beliefs, Clementina López-Medina, MD, PhD, and colleagues from the University of Cordoba (Spain), write in an accompanying editorial.

They highlight this study’s notable strengths, one of which was defining “active disease” as two or more swollen joints, which opened the study up to a larger patient population. The editorialists also underline the confirmation that leflunomide plus methotrexate reduces both joint symptoms and skin involvement in this subset of patients, which had also been found in a previous study.

“Leflunomide is usually considered as a second-line option after methotrexate is unsuccessful,” they note, “despite the fact that methotrexate did not show superiority over placebo in previous trials.”

The editorialists were not surprised that the combination therapy was more toxic than the monotherapy. Rheumatologists could use these data to individualize treatment accordingly, they write, while keeping an eye on “gastrointestinal disturbances.”

Overall, Dr. López-Medina and colleagues say that the study results should “be considered not only in daily clinical practice but also in the development of future recommendations.”

Leflunomide: Forgotten no longer, at least for PsA

“I think we probably underutilize leflunomide,” Arthur Kavanaugh, MD, professor of medicine and director of the Center for Innovative Therapy at the University of California, San Diego, told this news organization. “Sometimes medicines get ‘old,’ for lack of a better term, and fall a little bit of out of favor, sometimes unnecessarily. Leflunomide falls into that category. Because it’s older, it doesn’t get as much buzz as what’s new and shiny.

“I was not surprised by the results on the joints,” he said, “because we know from previous studies that leflunomide works in that regard. What did surprise me is that the skin got better, especially with the combination.”

Regarding the side effects for the combination therapy, he commended the authors for limiting potential uncertainty by using such a high dose of methotrexate.

“By going with a dose of 25 mg [per week], no one can say, ‘They pulled their punches and methotrexate monotherapy would’ve been just as good if it was given at a higher dose,’ “ he said. “And they also used leflunomide at a high dose. It makes you wonder: Could you use lower doses, and do lower doses mean fewer lab test abnormalities? This positive study does lend itself to some other permutations in terms of study design.

“Even though this was a small study,” he added, “it brings us right back to: We should really consider leflunomide in the treatment of PsA.”

The authors acknowledge their study’s limitations, including the fact that it was conducted in a single country and the absence of a nontreatment placebo group. They also note the higher percentage of women in the methotrexate plus leflunomide group, “which might have lowered the treatment response and increased the adverse event rate, resulting in bias.”

The study was funded by a Regional Junior Researcher Grant from Sint Maartenskliniek. The authors reported numerous potential conflicts of interest, including receiving payment, research grants, and consulting and speaker fees from various pharmaceutical companies.
