Apremilast (Otezla) monotherapy may be an effective option in oligoarticular psoriatic arthritis, Alexis R. Ogdie, MD, reported at the 2021 Rheumatology Winter Clinical Symposium.

Her analysis of apremilast data from the CORRONA Registry was among several recent highlights in psoriatic arthritis (PsA) cited by speakers at the meeting. Other significant developments included a large pan-Scandinavian study that reassuringly found no increased risk of solid cancers in tumor necrosis factor (TNF) inhibitor–treated patients with PsA, and evidence to suggest a sex difference in the efficacy of both secukinumab (Cosentyx) and adalimumab (Humira), with men responding better than women to two biologics with differing mechanisms of action.
 

A role for apremilast in oligoarticular disease?

Dr. Ogdie presented an analysis of 150 patients in the U.S. observational CORRONA Registry who initiated monotherapy for oligoarticular PsA and were followed for 6 months. Thirty-four started on apremilast, 15 on methotrexate, and 101 on a biologic. Even though the apremilast group had higher baseline disease activity than did those who started on methotrexate, at 6 months a swollen joint count of 1 or 0 was present in 41% of the apremilast-treated patients, compared with none on methotrexate and 15% on a biologic agent.

A tender joint count of 0-1 was documented at 6 months in 24% of patients on apremilast, 13% with methotrexate, and 21% on a biologic agent. Apremilast’s numeric superiority in outcomes compared to methotrexate in this exploratory study wasn’t subjected to statistical analysis because of the small sample size. However, the ongoing phase 4, double-blind, placebo-controlled, multicenter FOREMOST trial in 330 patients with early oligoarticular PsA should provide more definitive efficacy data, noted Dr. Ogdie, a rheumatologist and epidemiologist at the University of Pennsylvania, Philadelphia.

RWCS program director Arthur Kavanaugh, MD, said, “The most recent EULAR [European Alliance of Associations for Rheumatology] PsA guidelines totally discount apremilast, and I think mostly on the basis of cost, but then they also say that in groups of people it’s not as effective as methotrexate.”

“This study shows to me that, even though it’s a registry, with all the caveats about getting data from registries, apremilast certainly can be an effective drug,” said Dr. Kavanaugh, a rheumatologist and professor of medicine at the University of California, San Diego.

Another valuable piece of information from the CORRONA analysis is that it zeros in on patients with oligoarticular PsA.

“Almost all of our PsA studies are focused on people with polyarticular disease. What about those who have lesser involvement? That, of course, is important in the clinic,” he noted.

Dr. Ogdie concurred.

“If we study only polyarticular disease and we make all of our assumptions based on polyarticular disease, we might be leaving out at least half of the patients with PsA. And those patients may not need a bigger gun. Apremilast and methotrexate are kind of in the same group for that mild oligoarticular disease, and they probably work just fine,” she said.

A final point: “We really don’t have good outcome measures to study oligoarticular disease well. The ACR20 is not good because a 20% improvement in three joints is not readily measurable. That’s why trialists enroll patients with high joint count numbers,” according to the rheumatologist.

No increased risk of solid cancers in PsA patients treated with TNF inhibitors

A new analysis of clinical rheumatology registries in five Nordic countries finally puts to rest any concerns that treatment of PsA with TNF inhibitors is associated with increased risk of solid cancers. The same group previously reported no link between TNF inhibitors and lymphoma in PsA.

The solid cancers study included 9,655 PsA patients who started a first TNF inhibitor during 2001-2017, 14,809 others not treated with biologics, and 31,350 matched general population controls. Linkage to Swedish, Norwegian, Danish, Icelandic, and Finnish national cancer registries showed that the adjusted risk for solid cancer in TNF inhibitor–treated, compared with biologic-naive PsA patients, was 1.0. Similarly, the pooled standardized incidence ratio of solid cancer in TNF inhibitor–treated PsA patients compared to the general population was 1.0. There was no signal of a differential risk for incident cancer for any of the eight malignancies studied: lung, colorectal, breast, prostate, uterine, brain, liver, and pancreatic cancer.

“I like this study a lot because it’s specific to PsA rather than extrapolating from rheumatoid arthritis data, where we have a bunch more information for a much longer period of time, but it’s a different population,” Dr. Kavanaugh said.

Dr. Ogdie said, “I talk to my patients about this particular study or the same group’s earlier lymphoma study all the time.”

“I have to say, these are important data for the dermatology world because there are dermatologists who are still not convinced that TNF inhibitors don’t have an increased risk of malignancy. This kind of information is going to be helpful,” observed Eric M. Ruderman, MD, professor of medicine (rheumatology) at Northwestern University, Chicago.
 

Greater efficacy for biologics in males than females with PsA?

A secondary analysis of the phase 3b EXCEED trial raised the intriguing possibility that both secukinumab, an interleukin-17A inhibitor, and adalimumab, a TNF inhibitor, have greater efficacy in men than in women with PsA. In this randomized trial of 853 biologic-naive patients with PsA, the ACR20 response rate to secukinumab at week 52 was 61% in females versus 74% in males, with ACR50 rates of 43% in females and 55.3% in males. The ACR20 rate with adalimumab was 51.5% in females and 70.2% in males. Similarly, the corresponding ACR50s were 32.6% and 55.3%, respectively. Minimal disease activity was achieved in 36.2% of women and 51% of men on secukinumab, and in 24.2% of women and 49.8% of men on adalimumab.

“These are randomized patients, so you really shouldn’t see these big differences in minimal disease activity,” Dr. Ogdie noted. “The question is why do men seem to respond better to therapy than women? I don’t think it’s the fibromyalgia-ness. There’s probably some biologic rationale for this that we just don’t understand yet. Maybe hormonal interactions.”

This gender difference in response is an important issue because it can potentially distort outcomes in head-to-head drug trials, Dr. Ruderman added.

“That gender difference is not likely to be huge if you’re looking at a placebo-controlled trial because the difference between the active drug and placebo is going to outweigh it. But when you have two active drugs, if there’s an imbalance in terms of how many men or women there are on each of the two drugs, you may end up with an efficacy difference that’s not real but is based on gender and not response to the drug,” he explained.

Roy M. Fleischmann, MD, a rheumatologist and clinical trialist at the University of Texas, Dallas, rose from the audience to pronounce the EXCEED male-versus-female analysis “very interesting.”

“We should go back and look at other trials and see if that occurred, and if it did, then we have to think about that going forward,” he proposed.

Dr. Ogdie, Dr. Kavanaugh, and Dr. Ruderman reported having financial relationships with numerous pharmaceutical companies.

Only about 30% or fewer of patients with psoriatic arthritis (PsA) on therapy achieve disease remission by any definition. One reason for this may be inadequate attention to common comorbid conditions, Alexis Ogdie, MD, MSCE, declared at the 2021 Rheumatology Winter Clinical Symposium.

“I believe that addressing off-target aspects of disease is really important to improving the patient experience of their disease. We might need to target these directly in order to improve outcomes,” said Dr. Ogdie, a rheumatologist and epidemiologist at the University of Pennsylvania, Philadelphia, who coauthored the current American College of Rheumatology/National Psoriasis Foundation PsA guidelines.

Since rheumatologists are by now well informed about the increased cardiovascular risk associated with PsA, she focused on two common comorbidities that get less attention, both of which are associated with worse clinical outcomes in PsA: obesity and mental health issues.
 

Anxiety and depression

Dr. Ogdie was first author of a large, population-based, longitudinal cohort study of cause-specific mortality in 8,706 U.K. patients with PsA, 41,752 with RA, and more than 81,000 controls. Particularly striking was the finding of elevated mortality because of suicide in the rheumatic disease patients: a 203% increased risk in the PsA population, compared with the general population, and a 147% greater risk in patients with RA.

Overall, 30%-40% of PsA patients have comorbid depression and/or anxiety.

“That’s pretty striking. It’s also true for rheumatoid arthritis and axial spondyloarthritis. And if you’re depressed, you’re much less likely to respond to therapy in the way that we are measuring response to therapy,” Dr. Ogdie said.

Her approach to screening for depression and anxiety in her PsA patients, and indeed in all her other patients, is to begin by normalizing the topic, explaining to them that these affective disorders are common among patients with these disorders. She lets her patients know they can talk to her about it. And she informs them that, while effective treatment of their rheumatic disease may improve their depression or anxiety, managing those is also important for improving their disease. Additionally, understanding whether depression is present is important prior to prescribing certain medications. Apremilast (Otezla), for example, can worsen preexisting depression.

“Ask about signs and symptoms of depression,” Dr. Ogdie urged her colleagues. “I do this at every single visit in my review of symptoms. This is one I don’t skip. I ask: ‘Do you have any symptoms of depression or anxiety?’ ”

Structured evidence-based screening tools, many of which are well suited for completion during a patient’s preappointment check-in survey, include the Patient Health Questionnaire–2, the PHQ-9, the Patient-Reported Outcomes Measure Information System–10, PROMIS–Depression, and Routine Assessment of Patient Index Data 3.

“I also really like the PROMIS-29. It covers many domains of interest: depression and anxiety, sleep, fatigue, pain, physical function. It gives a lot of information about what’s going on in a patient’s life right now,” according to the rheumatologist.

The main thing is to regularly screen for anxiety and depression and then refer symptomatic patients for further assessment and treatment. This is not something that all rheumatologists have been trained to do.

Obesity

Dr. Ogdie was lead author of a national CORRONA Registry study which concluded that obese patients with PsA were only half as likely to achieve remission on a tumor necrosis factor (TNF) inhibitor, compared with nonobese patients. She believes the same holds true for all other types of therapy: Across the board, obesity is associated with a poor response. And obesity is much more common in PsA patients than the general population in every age group. Moreover, obesity is associated with risk factors for cardiovascular disease and is associated with fatty liver disease, two other major comorbid conditions in the PsA population.

The CORRONA Registry findings are supportive of an earlier Italian prospective, observational study of 135 obese and an equal number of normal-weight PsA patients, all of whom started on a TNF inhibitor and were followed for 24 months. In a multivariate-adjusted analysis, obesity was independently associated with a 390% higher risk of not achieving minimal disease activity.

The same Italian group subsequently conducted a prospective dietary intervention study in 138 overweight or obese patients with PsA starting anti-TNF therapy. A total of 59% of participants randomized to either of the two dietary interventions experienced at least a 5% weight loss at 6 months. The key study finding: Compared with the subjects with less than 5% weight loss, those with 5%-10% weight loss were 275% more likely to achieve minimal disease activity at 6 months, and in those with greater than 10% weight loss the likelihood of attaining minimal disease activity increased by 567%.

“We’re talking about a disease where treatments tested in clinical trials have odds ratios in the 1.2 range, compared with other therapies, so this is a really striking difference,” she observed.

Several studies have demonstrated that obesity in psoriasis patients is a risk factor for developing PsA. Recently, U.K. investigators took things a step further, reporting in a huge observational study that obese or overweight psoriasis patients who reduced their body mass index over a 10-year period had a corresponding reduction in the risk of developing PsA, compared with overweight or obese psoriasis patients whose BMI remained steady over the same period.

What’s needed now is access to programs to help patients with PsA lose weight. Health insurers are often unwilling to provide coverage. “We have a really tough time getting the patients in to see a nutritionist unless they’re willing to pay out of pocket,” Dr. Ogdie said.

Physical activity is an important element in successful weight loss. It also is recommended in practice guidelines for patients with inflammatory arthritis because of its salutary effects on disease activity scores, pain and stiffness, sleep, and quality of life. But a recent survey conducted by Dr. Ogdie and coworkers concluded that patients with PsA and other forms of inflammatory arthritis don’t receive much exercise guidance from their rheumatologists. About 60% of subjects were inactive. Those who were physically active typically engaged in aerobic exercise but were much less likely to do the other guideline-recommended forms of exercise, namely flexibility, balance, and resistance training. The patients’ report of low engagement of their physicians “suggests an opportunity for more prescriptive exercise discussions,” according to the investigators.

Diabetes, a critical risk factor for cardiovascular disease, occurs at an increased incidence in PsA. This was demonstrated in a U.K. cohort study coauthored by Dr. Ogdie. The study, which included nearly 4,200 individuals with PsA, concluded that they had a 43% greater incidence of diabetes than the general population in an analysis adjusted for body mass index, smoking, alcohol use, and demographics.

New-onset diabetes can be readily picked up by rheumatologists based upon the laboratory work they often order at patient office visits, or during their review of symptoms, she noted, and added that the U.S. Preventive Services Task Force recommends ordering a hemoglobin A1c test every 3 years.

Dr. Ogdie reported receiving research grants and/or consulting fees from numerous pharmaceutical companies. Her research is also funded by the National Institute of Arthritis and Musculoskeletal and Skin Diseases, the Rheumatology Research Foundation, and the National Psoriasis Foundation.

The same Italian group subsequently conducted a prospective dietary intervention study in 138 overweight or obese patients with PsA starting anti-TNF therapy. A total of 59% of participants randomized to either of the two dietary interventions experienced at least a 5% weight loss at 6 months. The key study finding: Compared with the subjects with less than 5% weight loss, those with 5%-10% weight loss were 275% more likely to achieve minimal disease activity at 6 months, and in those with greater than 10% weight loss the likelihood of attaining minimal disease activity increased by 567%.

“We’re talking about a disease where treatments tested in clinical trials have odds ratios in the 1.2 range, compared with other therapies, so this is a really striking difference,” she observed.

Several studies have demonstrated that obesity in psoriasis patients is a risk factor for developing PsA. Recently, U.K. investigators took things a step further, reporting in a huge observational study that obese or overweight psoriasis patients who reduced their body mass index over a 10-year period had a corresponding reduction in the risk of developing PsA, compared with overweight or obese psoriasis patients whose BMI remained steady over the same period.

What’s needed now is access to programs to help patients with PsA lose weight. Health insurers are often unwilling to provide coverage. “We have a really tough time getting the patients in to see a nutritionist unless they’re willing to pay out of pocket,” Dr. Ogdie said.

Physical activity is an important element in successful weight loss. It also is recommended in practice guidelines for patients with inflammatory arthritis because of its salutary effects on disease activity scores, pain and stiffness, sleep, and quality of life. But a recent survey conducted by Dr. Ogdie and coworkers concluded that patients with PsA and other forms of inflammatory arthritis don’t receive much exercise guidance from their rheumatologists. About 60% of subjects were inactive. Those who were physically active typically engaged in aerobic exercise but were much less likely to do the other guideline-recommended forms of exercise, namely flexibility, balance, and resistance training. The patients’ report of low engagement of their physicians “suggests an opportunity for more prescriptive exercise discussions,” according to the investigators.

Diabetes, a critical risk factor for cardiovascular disease, occurs at an increased incidence in PsA. This was demonstrated in a U.K. cohort study coauthored by Dr. Ogdie. The study, which included nearly 4,200 individuals with PsA, concluded that they had a 43% greater incidence of diabetes than the general population in an analysis adjusted for body mass index, smoking, alcohol use, and demographics.

New-onset diabetes can be readily picked up by rheumatologists based upon the laboratory work they often order at patient office visits, or during their review of symptoms, she noted, and added that the U.S. Preventive Services Task Force recommends ordering a hemoglobin A1c test every 3 years.

Only about 30% or fewer of patients with psoriatic arthritis (PsA) on therapy achieve disease remission by any definition. One reason for this may be inadequate attention to common comorbid conditions, Alexis Ogdie, MD, MSCE, declared at the 2021 Rheumatology Winter Clinical Symposium.

“I believe that addressing off-target aspects of disease is really important to improving the patient experience of their disease. We might need to target these directly in order to improve outcomes,” said Dr. Ogdie, a rheumatologist and epidemiologist at the University of Pennsylvania, Philadelphia, who coauthored the current American College of Rheumatology/National Psoriasis Foundation PsA guidelines.

Since rheumatologists are by now well informed about the increased cardiovascular risk associated with PsA, she focused on two common comorbidities that get less attention, both of which are associated with worse clinical outcomes in PsA: obesity and mental health issues.
 

Anxiety and depression

Dr. Ogdie was first author of a large, population-based, longitudinal cohort study of cause-specific mortality in 8,706 U.K. patients with PsA, 41,752 with RA, and more than 81,000 controls. Particularly striking was the finding of elevated mortality because of suicide in the rheumatic disease patients: a 203% increased risk in the PsA population, compared with the general population, and a 147% greater risk in patients with RA.

Overall, 30%-40% of PsA patients have comorbid depression and/or anxiety.

“That’s pretty striking. It’s also true for rheumatoid arthritis and axial spondyloarthritis. And if you’re depressed, you’re much less likely to respond to therapy in the way that we are measuring response to therapy,” Dr. Ogdie said.

Her approach to screening for depression and anxiety in her PsA patients, and indeed in all her other patients, is to begin by normalizing the topic, explaining to them that these affective disorders are common among patients with these disorders. She lets her patients know they can talk to her about it. And she informs them that, while effective treatment of their rheumatic disease may improve their depression or anxiety, managing those is also important for improving their disease. Additionally, understanding whether depression is present is important prior to prescribing certain medications. Apremilast (Otezla), for example, can worsen preexisting depression.

“Ask about signs and symptoms of depression,” Dr. Ogdie urged her colleagues. “I do this at every single visit in my review of symptoms. This is one I don’t skip. I ask: ‘Do you have any symptoms of depression or anxiety?’ ”

Structured evidence-based screening tools, many of which are well suited for completion during a patient’s preappointment check-in survey, include the Patient Health Questionnaire–2, the PHQ-9, the Patient-Reported Outcomes Measure Information System–10, PROMIS–Depression, and Routine Assessment of Patient Index Data 3.

“I also really like the PROMIS-29. It covers many domains of interest: depression and anxiety, sleep, fatigue, pain, physical function. It gives a lot of information about what’s going on in a patient’s life right now,” according to the rheumatologist.

The main thing is to regularly screen for anxiety and depression and then refer symptomatic patients for further assessment and treatment. This is not something that all rheumatologists have been trained to do.

Obesity

Dr. Ogdie was lead author of a national CORRONA Registry study which concluded that obese patients with PsA were only half as likely to achieve remission on a tumor necrosis factor (TNF) inhibitor, compared with nonobese patients. She believes the same holds true for all other types of therapy: Across the board, obesity is associated with a poor response. And obesity is much more common in PsA patients than the general population in every age group. Moreover, obesity is associated with risk factors for cardiovascular disease and is associated with fatty liver disease, two other major comorbid conditions in the PsA population.

The CORRONA Registry findings are supportive of an earlier Italian prospective, observational study of 135 obese and an equal number of normal-weight PsA patients, all of whom started on a TNF inhibitor and were followed for 24 months. In a multivariate-adjusted analysis, obesity was independently associated with a 390% higher risk of not achieving minimal disease activity.

Sonelokinab, an investigational interleukin-17A/F (IL-A/F)–targeted agent utilizing a novel therapeutic platform known as a nanobody, achieved exceptionally rapid and clinically meaningful improvement in moderate to-severe chronic plaque psoriasis in a phase 2b randomized trial, Kim A. Papp, MD, PhD, reported at the annual congress of the European Academy of Dermatology and Venereology.

A nanobody is a tiny antibody fragment with a much smaller molecular weight than the monoclonal antibodies utilized today in treating psoriasis or atopic dermatitis. The sonelokinab nanobody, derived from animals in the camel family, is a recombinant sequence-optimized nanobody specific for human IL-17F, IL-17A, the heterodimer IL-17A/F, and serum albumin. The binding to serum albumin give sonelokinab a lengthy half-life of 10-12 hours, which may be therapeutically relevant, explained Dr. Papp, president and founder of Probity Medical Research in Waterloo, Ont.

He presented the 24-week results of a multicenter, double-blind, double-dummy randomized trial including 313 North American and European adults with an average 18-year history of psoriasis and a baseline Psoriasis Area and Severity Index (PASI) score of about 21. They were randomized to one of six treatment arms for the first 12 weeks: subcutaneous injection of sonelokinab at 30, 60, or 120 mg at weeks 0, 2, 4, and 8; enhanced–loading-dose sonelokinab at 120 mg every 2 weeks through week 10; the IL-17A inhibitor secukinumab (Cosentyx) at its standard dosing as an active comparator; or placebo. Data analysis was by rigorous nonresponder imputation, meaning anyone who didn’t complete the study was scored as a nonresponder.

“This yields a conservative data analysis somewhat biased against sonelokinab,” the dermatologist pointed out.

The primary outcome in the trial was the week-12 rate of an Investigator’s Global Assessment score of 0 or 1, indicative of clear or almost clear skin. This was achieved in 88.2% of patients in the highest-dose arm of sonelokinab. That group also had a week-12 PASI 90 response rate of 76.5% and a PASI 100 response rate of 33.3%. By comparison, patients on standard-dose secukinumab had a less robust week-12 IGA 0/1 rate of 77.4%, a PASI 90 of 64.2%, and a PASI 100 of 28.3%. Of note, however, this secukinumab performance was better than seen in the 30-mg sonelokinab group, and comparable to outcomes with 60 mg of sonelokinab.

Dose escalation was performed from weeks 12-24. Patients with a week-12 IGA score greater than 1 after being on sonelokinab at 30 or 60 mg were upgraded to 120 mg at week 12 and again every 4 weeks thereafter. Placebo-treated controls were switched to 120 mg at weeks 12, 14, 16, and every 4 weeks thereafter. The group on the enhanced–loading-dose sonelokinab moved to 120 mg every 4 weeks, while those who had gotten four doses of sonelokinab at 120 mg during the first 12 weeks were switched to 120 mg every 8 weeks. The secukinumab group remained on the approved dosing through week 24.

At week 24, superior outcomes were seen in the enhanced–loading-dose sonelokinab group, with an IGA 0/1 response rate of 94.2%, a PASI 90 of 90.4%, and a PASI 100 of 56.9%. The corresponding week-24 rates in patients on 120 mg of sonelokinab every 8 weeks from week 12 on were 80.4%, 79.2%, and 40.4%, outcomes similar to those seen with secukinumab.

The rapidity of response to sonelokinab at 120 mg was striking, with approximately one-third of treated patients achieving a PASI 90 response by week 4.

“This could reflect the smaller molecular profile. There is possibly rapid increased absorption or bioavailability, quicker time to achieving serum half-life, better penetration into target tissue, and perhaps more effective engagement at the target. All of those things are possibilities. These are things that are yet to be explored, but it’s very enticing to see that uncharacteristically rapid initial response. It’s all very gratifying – and tantalizing,” Dr. Papp said in response to an audience question.

The safety profile of sonelokinab was reassuring. The most common adverse events were nasopharyngitis in 13.5% of patients and pruritus in 6.7%, with most cases being mild or moderate. As with other IL-17 blockers, there was an increase in oral candidiasis. This side effect appeared to occur in dose-dependent fashion: The incidence was zero in the 30-mg group, 1.9% with 60 mg, 3.8% with sonelokinab at 120 mg without an enhanced loading dose, and 5.9% with the enhanced loading dose.

The study was conducted by Avillion in partnership with Merck. Dr. Papp reported receiving research funding from and serving as a consultant to those and numerous other pharmaceutical companies.

Differences in gene expression between the skin and synovial tissues of individuals with psoriatic arthritis could explain why treatments targeting proinflammatory mechanisms don’t improve joint symptoms in some patients.

SilverV/Thinkstock

A paper published in Annals of the Rheumatic Diseases presents the results of an observational, open-label study involving 27 patients with active psoriatic arthritis, 18 of whom were treated with anti–tumor necrosis factor (anti-TNF) therapies and 9 with the monoclonal antibody ustekinumab (Stelara). This drug targets the axis of proinflammatory cytokine interleukin-23 and effector cytokine IL-12, which are believed to play an important role both in skin and nail psoriasis, and psoriatic arthritis.

However, while anti–IL-23 antibodies seem to work well to address skin manifestations of psoriasis, they tend to improve joint symptoms only in selected patients.

“The lack of a clear mechanism to explain such divergent responses prompted this study,” said Dr. Alessandra Nerviani, lead author of the study, from the Barts and The London School of Medicine & Dentistry.

Participants also had biopsies taken from the synovium – in particular, from joints that were clinically and ultrasonographically active – and from lesional and nonlesional skin for gene expression analysis.

In terms of treatment response, the ustekinumab-treated group showed significantly higher scores for erythrocyte sedimentation rate, joint pain, and disease activity, compared with the anti–TNF-treated group. Psoriasis Area and Severity Index scores were similar in both treatment arms, but significantly more patients in the anti-TNF group met the EULAR Disease Activity Score for response (70.6% vs. 22.2%).

The gene expression analysis, which assessed the activity of 80 genes related to inflammation in 14 patient samples from synovial tissue, lesional skin, and nonlesional skin, found that patterns of expression in the synovium clustered away from those from skin.

This was particularly the case when it came to genes related to drug targets. The targets for anti-TNF showed similar levels of expression in both skin and synovial tissue. However, the targets for ustekinumab – namely interleukin (IL)–23A, IL-23R and, IL-12B – showed higher levels of expression in lesional skin than in nonlesional skin and synovial tissue.

“Interestingly, we observed that, while some patients did express IL-23 cytokines/receptor in both skin and joint, others had discordant expression, that is, active IL-23 pathway in the lesional skin but not in the synovium,” the authors wrote.

When researchers then stratified patients according to how much synovial inflammation they had, they found that patients who had higher scores also showed higher expression of genes for IL-12B and IL-23R, but not IL-23A, despite showing no other major clinical differences.

The authors also looked at the protein expression levels for IL-23p40, IL-23p19 and IL-23R, and found that while the percentage of cells positive for these proteins was significantly higher in lesional, compared with nonlesional skin, it was also higher in the synovium among patients with more inflammation.

“Except for the LIKERT patient score, we did not detect other significant correlations between IL-23 axis expression and clinical parameters at baseline, suggesting that patients with comparable disease severity may have, in fact, heterogeneous histopathological features and expression of drug targets within the diseased synovium,” they wrote.

More selective expression of IL-23 in synovium

Commenting on the findings, the authors highlighted that the expression of targets for anti-TNF was much more homogeneous across skin and synovial tissue, but the IL-23A/IL-12B/IL-23R genes generally showed higher levels of expression in lesional skin. compared with either nonlesional skin or synovium. However, even within the synovium, expression of these genes varied enormously, from levels similar to those seen in paired lesional skin to levels well below those.

“It is plausible to speculate that an overall higher presence of IL-23 in the psoriatic skin supports the concept of a generally better response in terms of skin manifestations, including almost complete clearance of psoriatic lesions,” Dr. Nerviani said in an interview. “While, on the other hand, the more selective expression of IL-23 in the synovium, namely in histologically more inflamed synovium characterized by immune cells infiltration, may explain the overall more modest success to meet stringent response criteria in the joints.“

Of particular significance was the observation that IL-12B and IL-23R transcription levels were higher in patients with higher levels of synovial tissue inflammation.

“We confirmed that IL-23 axis expression relates to the synovial histopathology not only in PsA at different stages of the disease, including early treatment-naive patients, but also in the early phase of RA, investigated as disease control,” they wrote.

Dr. Nerviani said the results could inform a more tailored “precision medicine” approach to treating patients with psoriatic arthritis.

“While randomized synovial biopsy–driven clinical trials are now a reality in rheumatoid arthritis, in psoriatic arthritis, these kinds of studies have not been performed yet but may become actual in the future,” she said. “An in-depth characterization of the synovial tissue represents the first essential step towards addressing current unmet clinical needs and, potentially, changing our practice.”

However, she stressed that the study was not powered to test the correlation between the expression level of these pathways in disease tissue and clinical response to treatment.

“Further dedicated clinical trials should be designed to look at the relationship between synovial pathology and molecular characteristics, and response to targeted treatment to address this question,” Dr. Nerviani said.

The study was supported by the Queen Mary University of London and the Fondazione Ceschina, and in part by grants from Versus Arthritis. No conflicts of interest were declared.

Psoriasis Area and Severity Index scores were similar in both treatment arms, but significantly more patients in the anti-TNF group met the EULAR Disease Activity Score for response (70.6% vs. 22.2%).

The gene expression analysis, which assessed the activity of 80 genes related to inflammation in 14 patient samples from synovial tissue, lesional skin, and nonlesional skin, found that patterns of expression in the synovium clustered away from those from skin.

This was particularly the case when it came to genes related to drug targets. The targets for anti-TNF showed similar levels of expression in both skin and synovial tissue. However, the targets for ustekinumab – namely interleukin (IL)–23A, IL-23R and, IL-12B – showed higher levels of expression in lesional skin than in nonlesional skin and synovial tissue.

“Interestingly, we observed that, while some patients did express IL-23 cytokines/receptor in both skin and joint, others had discordant expression, that is, active IL-23 pathway in the lesional skin but not in the synovium,” the authors wrote.

When researchers then stratified patients according to how much synovial inflammation they had, they found that patients who had higher scores also showed higher expression of genes for IL-12B and IL-23R, but not IL-23A, despite showing no other major clinical differences.

The authors also looked at the protein expression levels for IL-23p40, IL-23p19 and IL-23R, and found that while the percentage of cells positive for these proteins was significantly higher in lesional, compared with nonlesional skin, it was also higher in the synovium among patients with more inflammation.

“Except for the LIKERT patient score, we did not detect other significant correlations between IL-23 axis expression and clinical parameters at baseline, suggesting that patients with comparable disease severity may have, in fact, heterogeneous histopathological features and expression of drug targets within the diseased synovium,” they wrote.

More selective expression of IL-23 in synovium

Commenting on the findings, the authors highlighted that the expression of targets for anti-TNF was much more homogeneous across skin and synovial tissue, but the IL-23A/IL-12B/IL-23R genes generally showed higher levels of expression in lesional skin. compared with either nonlesional skin or synovium. However, even within the synovium, expression of these genes varied enormously, from levels similar to those seen in paired lesional skin to levels well below those.

“It is plausible to speculate that an overall higher presence of IL-23 in the psoriatic skin supports the concept of a generally better response in terms of skin manifestations, including almost complete clearance of psoriatic lesions,” Dr. Nerviani said in an interview. “While, on the other hand, the more selective expression of IL-23 in the synovium, namely in histologically more inflamed synovium characterized by immune cells infiltration, may explain the overall more modest success to meet stringent response criteria in the joints.“

Of particular significance was the observation that IL-12B and IL-23R transcription levels were higher in patients with higher levels of synovial tissue inflammation.

“We confirmed that IL-23 axis expression relates to the synovial histopathology not only in PsA at different stages of the disease, including early treatment-naive patients, but also in the early phase of RA, investigated as disease control,” they wrote.

Dr. Nerviani said the results could inform a more tailored “precision medicine” approach to treating patients with psoriatic arthritis.

“While randomized synovial biopsy–driven clinical trials are now a reality in rheumatoid arthritis, in psoriatic arthritis, these kinds of studies have not been performed yet but may become actual in the future,” she said. “An in-depth characterization of the synovial tissue represents the first essential step towards addressing current unmet clinical needs and, potentially, changing our practice.”

However, she stressed that the study was not powered to test the correlation between the expression level of these pathways in disease tissue and clinical response to treatment.

“Further dedicated clinical trials should be designed to look at the relationship between synovial pathology and molecular characteristics, and response to targeted treatment to address this question,” Dr. Nerviani said.

The study was supported by the Queen Mary University of London and the Fondazione Ceschina, and in part by grants from Versus Arthritis. No conflicts of interest were declared.

Differences in gene expression between the skin and synovial tissues of individuals with psoriatic arthritis could explain why treatments targeting proinflammatory mechanisms don’t improve joint symptoms in some patients.

SilverV/Thinkstock

A paper published in Annals of the Rheumatic Diseases presents the results of an observational, open-label study involving 27 patients with active psoriatic arthritis, 18 of whom were treated with anti–tumor necrosis factor (anti-TNF) therapies and 9 with the monoclonal antibody ustekinumab (Stelara). This drug targets the axis of proinflammatory cytokine interleukin-23 and effector cytokine IL-12, which are believed to play an important role both in skin and nail psoriasis, and psoriatic arthritis.

However, while anti–IL-23 antibodies seem to work well to address skin manifestations of psoriasis, they tend to improve joint symptoms only in selected patients.

“The lack of a clear mechanism to explain such divergent responses prompted this study,” said Dr. Alessandra Nerviani, lead author of the study, from the Barts and The London School of Medicine & Dentistry.

Participants also had biopsies taken from the synovium – in particular, from joints that were clinically and ultrasonographically active – and from lesional and nonlesional skin for gene expression analysis.

In terms of treatment response, the ustekinumab-treated group showed significantly higher scores for erythrocyte sedimentation rate, joint pain, and disease activity, compared with the anti–TNF-treated group. Psoriasis Area and Severity Index scores were similar in both treatment arms, but significantly more patients in the anti-TNF group met the EULAR Disease Activity Score for response (70.6% vs. 22.2%).

LAS VEGAS – Current major guidelines for treatment of psoriatic arthritis (PsA) shortchange the value of the anti–interleukin-17 biologics for this disease, Kenneth B. Gordon, MD, said at MedscapeLive’s annual Las Vegas Dermatology Seminar, held virtually this year.

The 2018 joint American College of Rheumatology/National Psoriasis Association guidelines recommend the anti–tumor necrosis factor agents as first-line biologic therapy for PsA, with the anti–IL-17 biologics held in reserve as second-tier therapy for when the anti-TNFs don’t work. That’s largely because the guidance was developed before the compelling evidence for the anti–IL-17 agents as the biologics of choice was appreciated, according to Dr. Gordon, professor and chair of the department of dermatology at the Medical College of Wisconsin, Milwaukee.

“Many people go by these guidelines,” the dermatologist noted. “I think it’s really critical to look at the data and not just the guidelines because the guidelines don’t give full credit to the anti–IL-17 agents,” he added.

“Emerging psoriatic arthritis data may likely put this class of medications into the forefront of treatment for patients who have both psoriasis and psoriatic arthritis because you generally get higher responses for the skin disease than with anti-TNF therapy, and with similar responses in psoriatic arthritis.”

Two IL-17 inhibitors are approved for both PsA and psoriasis: secukinumab (Cosentyx) and ixekizumab (Taltz). In addition, brodalumab (Siliq), approved for psoriasis, is expected to receive an expanded indication for PsA based upon its strong showing in the AMVISION-1 and -2 trials. Data from those trials, as well as the FUTURE 2 trial for secukinumab and SPIRIT-P1 for ixekizumab, consistently document at least 20% improvement in the ACR criteria for PsA severity – that is, an ACR 20 response – in 50%-60% of patients on one of the three IL-17 inhibitors, as well as ACR 50 response rates of around 30%. Those outcomes are quite consistent with the impact of the anti-TNF biologics on joint disease. But the TNF inhibitors can’t touch the anti–IL-17 biologics when it comes to improvement in Psoriasis Area and Severity Index (PASI) scores: The anti–IL-17 agents have week-52 PASI 75 response rates in the range of 80%, PASI 90 response rates of 70%-75%, and PASI 100 response rates of 40%-55%, with the highest-end results being seen with brodalumab, he continued.

A point worth remembering when prescribing secukinumab is that the approved dose for PsA is 150 mg every 4 weeks, which is just half of the typical dose in psoriasis.

“I spend a lot of time convincing my rheumatology colleagues that if you’re treating both psoriasis and psoriatic arthritis, use the psoriasis dose. There’s some evidence that the higher dose provides some benefit in terms of prevention of permanent joint damage by x-ray,” Dr. Gordon said.

Evidence that TNF inhibitors inhibit permanent joint damage in patients with PsA has been considered a major advantage, establishing this medication class as first-line biologic therapy. But anti–IL-17 therapies appear to have a similar beneficial effect. That was demonstrated in the SPIRIT-P1 trial, where Sharp scores – a radiographic measure of progression of joint damage – were similar at 24 weeks in PsA patients randomized to ixekizumab as compared to adalimumab, with both biologics being superior to placebo. An Assessment of SpondyloArthritis International Society 20% improvement (ASAS 20) response or an ACR 50 response doesn’t capture what’s going on with regard to axial disease. That’s assessed through ASAS 20 and ASAS 40 responses – that is, at least 20% or 40% improvement, compared with baseline, in Assessment in Ankylosing Spondylitis scores. And in the MEASURE 1 and 2 trials, secukinumab achieved robust improvement in axial disease as reflected in favorable ASAS 20 and ASAS 40 responses through 52 weeks in patients with active ankylosing spondylitis.

“The anti–IL-17 agents do actually work in ankylosing spondylitis, which might be a surrogate for the treatment effect in axial psoriatic arthritis,” Dr. Gordon commented.

The phase 3b MAXIMISE trial presented at the 2019 EULAR meeting looked specifically at the impact of secukinumab in patients with psoriatic arthritis with axial involvement. An ASAS 20 response at week 12 was seen in 67% and 65% of patients randomized to secukinumab at 150 or 300 mg, respectively, if they were on concomitant methotrexate, and 64% and 61% if they were not, compared with ASAS 20 rates of 34% and 31% in placebo-treated controls.

“This is the only study of an anti–IL-17 agent that’s been done for axial disease to date in psoriatic arthritis. It’s very, very encouraging,” the dermatologist commented.

 

Durability of response and safety

“In terms of safety, the anti–IL-17s have been a truly remarkable success story. There are very low rates of things to be concerned about,” Dr. Gordon said.

Oral candidiasis occurs in 2%-4% of treated patients, but he noted, “It’s almost always very mild disease” that’s easily treatable with nystatin or, in the worst case, with some fluconazole.

Inflammatory bowel disease (IBD) as a side effect of anti–IL-17 therapy has been a controversial issue. Dr. Gordon’s interpretation of the evidence is that there probably is a very slight increase in the risk of developing ulcerative colitis, but not Crohn’s disease.

“This rate is extraordinarily low, so while it’s something that I consider, and if a patient has a personal history of IBD I will sometimes hesitate to use an anti–IL-17 agent, in patients who don’t have a personal history I’ll go ahead,” he explained.

There is a signal of a slight increase in risk of depression in patients on brodalumab, which isn’t the case for secukinumab or ixekizumab.

Importantly, large long-term extension studies with years of follow-up show that the initially low adverse event rates associated with the IL-17 inhibitors don’t increase over time; rather, they remain steady over years of use.

Long-term maintenance of response with these biologics is impressive. “It’s not perfect, but it’s still a tremendous advantage for patients, especially if you can get them through that initial period,” Dr. Gordon said.

For example, in the long-term extension of the UNCOVER-1 trial, psoriasis patients who had clear or almost clear skin at week 12 on ixekizumab and continued to take the medication open label for 5 years had PASI 75, 90, and 100 response rates of 94%, 82%, and 47%, respectively, at week 264.
 

What about IL-12/23 and IL-23 inhibitors in PsA?

In a separate presentation at the MedscapeLive seminar, Bruce E. Strober, MD, PhD, said that, although ustekinumab (Stelara) is approved for both psoriasis and PsA, the IL-12/-23 inhibitor’s efficacy in PsA is inconsistent and lower than other approved biologics. In contrast, the IL-23 inhibitor guselkumab (Tremfya), which also has the dual indications, is a strong performer in both. In the DISCOVER-2 trial, conducted in treatment-naive patients with PsA, guselkumab at the approved dose of 100 mg every 8 weeks achieved ACR 20, 50, and 70 rates of 64%, 31%, and 19%, respectively. It was also significantly better than placebo for resolution of enthesitis.

An important caveat: While radiographic inhibition of progression of joint disease occurred with guselkumab dosed at 100 mg every 4 weeks in DISCOVER-2, that’s not the approved dose. At 100 mg every 8 weeks – the FDA-approved dosing for both psoriatic arthritis and psoriasis – radiographic inhibition wasn’t better than with placebo, noted Dr. Strober, a dermatologist at Yale University, New Haven, Conn.

Dr. Gordon and Dr. Strober are clinical trialists who reported receiving research support and/or honoraria from more than a dozen pharmaceutical companies, including virtually all of those with biologics for dermatology.

Long-term maintenance of response with these biologics is impressive. “It’s not perfect, but it’s still a tremendous advantage for patients, especially if you can get them through that initial period,” Dr. Gordon said.

For example, in the long-term extension of the UNCOVER-1 trial, psoriasis patients who had clear or almost clear skin at week 12 on ixekizumab and continued to take the medication open label for 5 years had PASI 75, 90, and 100 response rates of 94%, 82%, and 47%, respectively, at week 264.
 

What about IL-12/23 and IL-23 inhibitors in PsA?

In a separate presentation at the MedscapeLive seminar, Bruce E. Strober, MD, PhD, said that, although ustekinumab (Stelara) is approved for both psoriasis and PsA, the IL-12/-23 inhibitor’s efficacy in PsA is inconsistent and lower than other approved biologics. In contrast, the IL-23 inhibitor guselkumab (Tremfya), which also has the dual indications, is a strong performer in both. In the DISCOVER-2 trial, conducted in treatment-naive patients with PsA, guselkumab at the approved dose of 100 mg every 8 weeks achieved ACR 20, 50, and 70 rates of 64%, 31%, and 19%, respectively. It was also significantly better than placebo for resolution of enthesitis.

An important caveat: While radiographic inhibition of progression of joint disease occurred with guselkumab dosed at 100 mg every 4 weeks in DISCOVER-2, that’s not the approved dose. At 100 mg every 8 weeks – the FDA-approved dosing for both psoriatic arthritis and psoriasis – radiographic inhibition wasn’t better than with placebo, noted Dr. Strober, a dermatologist at Yale University, New Haven, Conn.

Dr. Gordon and Dr. Strober are clinical trialists who reported receiving research support and/or honoraria from more than a dozen pharmaceutical companies, including virtually all of those with biologics for dermatology.

Adults with active psoriatic arthritis (PsA) treated with guselkumab (Tremfya) showed significant improvement in American College of Rheumatology response criteria and disease activity after 1 year, based on data from the phase 3 DISCOVER-2 trial.

The findings, published in Arthritis & Rheumatology, extend the previously published 24-week, primary endpoint results of the trial, which tested guselkumab for adults with PsA who had not previously taken a biologic drug. Guselkumab was approved in July 2020 in the United States.

Iain B. McInnes, MD, PhD, of the University of Glasgow and his colleagues described guselkumab as “a fully-human monoclonal antibody specific to interleukin (IL)-23’s p19-subunit” that offers a potential alternative for PsA patients who discontinue their index tumor necrosis factor inhibitor because of insufficient efficacy.

The study enrolled 739 PsA patients at 118 sites worldwide. Participants were randomized to receive subcutaneous injections of 100 mg guselkumab every 4 weeks; 100 mg guselkumab at week 0 and 4, then every 8 weeks; or a placebo; 238 placebo-treated patients crossed over at 24 weeks to receive 100 mg guselkumab every 4 weeks. Patients on nonbiologic disease-modifying antirheumatic drugs at baseline were allowed to continue stable doses. Overall, about 93% of patients originally randomized to the three groups remained on guselkumab at 52 weeks.

Overall, 71% and 75% of 4-week and 8-week guselkumab patients, respectively, showed an improvement of at least 20% from baseline in ACR response criteria components at 52 weeks, which was up from 64% of patients seen at 24 weeks in both groups.

The study participants had an average disease duration of more than 5 years with no biologic treatment, and an average of 12-13 swollen joints and 20-22 tender joints at baseline. Approximately half were male, half had psoriasis or dactylitis, and two-thirds had enthesitis. Skin disease severity was assessed using the Investigator’s Global Assessment and Psoriasis Area Severity Index (PASI).

At 52 weeks, 75% and 58% of patients in the guselkumab groups had resolution of dactylitis and enthesitis, respectively. In addition, 86% of patients in both guselkumab groups achieved PASI 75 at 52 weeks, and 58% and 53% of the 4-week and 8-week groups, respectively, achieved PASI 100.

In addition, patients treated with guselkumab showed low levels of radiographic progression and significant improvements from baseline in measures of physical function and quality of life.

The most frequently reported adverse events in guselkumab patients were upper respiratory tract infections, nasopharyngitis, bronchitis, and investigator-reported laboratory values of increased alanine aminotransferase and aspartate aminotransferase; these rates were similar to those seen in the previously published 24-week data. Approximately 2% of guselkumab and placebo patients discontinued their treatments because of adverse events.

No patient developed an opportunistic infection or died during the study period.

The study findings were limited by several factors including the relatively short 1-year duration, the shorter duration of placebo, compared with guselkumab, and by potential confounding from missing data on patients who discontinued, the researchers noted. However, the results support the effectiveness of guselkumab for improving a range of manifestations of active PsA, and the overall treatment and safety profiles seen at 24 weeks were maintained, they said.

“Data obtained during the second year of DISCOVER-2 will augment current knowledge of the guselkumab benefit-risk profile and further our understanding of longer-term radiographic outcomes with both guselkumab dosing regimens,” they concluded.

The study was supported by Janssen. Many authors reported financial relationships with Janssen and other pharmaceutical companies. Nine of the 15 authors are employees of Janssen (a subsidiary of Johnson & Johnson) and own Johnson & Johnson stock or stock options.

Christina Chambers, PhD, MPH, who runs the MotherToBaby Pregnancy Studies research center at the University of California, San Diego, has found most pregnant women to be “entirely altruistic” about sharing their experiences with drug treatment during pregnancy.

Christina Chambers

This is good news for the growth of more information about the safety of biologics and other drugs during pregnancy. Pregnancy outcomes data are increasingly emerging – particularly for tumor necrosis factor (TNF) inhibitors – but dermatologists, rheumatologists, and their female patients with psoriasis and psoriatic arthritis (PsA) want much more.

And women’s participation in the MotherToBaby studies conducted by the nonprofit Organization of Teratology Information Specialists (OTIS) is key, say physicians who are treating women of reproductive age. OTIS is now listed in drug labeling as the “pregnancy registry” contact for many of the medications they may be discussing with patients.

Dr. Chambers said that most women appreciate “that participating in a study may not help her with her pregnancy, but it can help her sister or her friend or someone else who has these same questions in planning a pregnancy of ‘Can I stay on my treatment?’ or, in the case of an unplanned pregnancy, ‘Should I be concerned?’ ”

OTIS has enrolled women with psoriasis and/or PsA in studies of nine medications, most of them biologics (both TNF-alpha blockers and newer anti-interleukin agents).

Four of the studies – those evaluating etanercept (Enbrel), adalimumab (Humira), abatacept (Orencia), and ustekinumab (Stelara) – are now closed to enrollment with analyses either underway or completed. The other five are currently enrolling patients and involve treatment with certolizumab pegol (Cimzia), tildrakizumab (Ilumya), apremilast (Otezla), guselkumab (Tremfya), and tofacitinib (Xeljanz).

Lisa R. Sammaritano, MD, a rheumatologist at the Hospital for Special Surgery, New York, who led the development of the American College of Rheumatology’s first guideline for the management of reproductive health in rheumatic and musculoskeletal diseases, recommends to some of her patients that they contact OTIS. “Their pregnancy registry studies have added important information to the field over the years,” she said.

Most recently, a study of the anti–TNF-alpha medication adalimumab that began in 2004 in pregnant patients with RA and Crohn’s disease culminated in a 2019 PLOS ONE paper reporting no associations between exposure to the medication and an increased risk of adverse outcomes. The outcomes studied were major structural birth defects, minor defects, spontaneous abortion, preterm delivery, prenatal and postnatal growth deficiency, serious or opportunistic infections, and malignancies.

An analysis is underway of adalimumab exposure in women with PsA – a patient subset that was added after the study started. But in the meantime, Dr. Chambers said, the 2019 research article is relevant to questions of drug safety across indications.

OTIS’s MothertoBaby studies are structured as prospective cohort studies. Dr. Chambers, a perinatal epidemiologist, is president of OTIS, which recruits women who have an exposure to the medication under study – at least one dose, for any length of time. And in most cases, it also recruits women with the underlying condition but no exposure and healthy women without the condition to represent the general population.

It’s the disease-matched comparison group that makes OTIS’s studies different from traditional pregnancy registries involving “a simple exposure series and outcomes that are described in the context of what you’d expect in the general population,” said Dr. Chambers, professor in the department of pediatrics, as well as family and preventative medicine, at UCSD and codirector of the Center for Better Beginnings at that university. “Many maternal conditions themselves [or their comorbidities] carry some risk of adverse outcomes in pregnancy.”

The OTIS studies typically involve at least 100 exposed pregnancies and a similar number of unexposed pregnancies; some have cohorts of 200-300.

The recently published study of adalimumab, for instance, included 257 women with exposure to the drug and 120 women in a disease comparison group with no exposure. In addition to finding no associations between drug exposure and adverse outcomes, the study found that women with RA or Crohn’s were at increased risk of preterm delivery, irrespective of adalimumab exposure.

“There’s insufficient [power with any of these numbers] to come to the conclusion that a drug is safe,” she said. “But what we have been able to say [through our studies] is that we’ve looked carefully at the whole array of outcomes ... and we don’t see anything unusual. That early view can be reassuring” until large population-based studies or claims analyses become possible.

Dr. Sammaritano, also with Weill Cornell Medicine, New York, said that she does not recommend registry participation for patients who stop biologics at the diagnosis of pregnancy. Since “the start of IgG antibody transfer during pregnancy is about 16 weeks,” she worries that including these patients might lead to falsely reassuring findings. “We are most interested in [knowing the outcomes of] patients who must continue the drugs through pregnancy,” she said.

Dr. Chambers, however, said that in her view, placental transfer is not a requirement for a medication to have some effect on the outcome of pregnancy. “The outcome could be influenced by an effect of the medication that doesn’t require placental transfer or require placental transfer in large amounts,” she said. “So it’s relevant to examine exposures that have occurred only in the first trimester, and this is especially true for the outcome of major birth defects, most of which are initiated in the first trimester.”

The MotherToBaby studies typically include both early, short exposures and longer exposures, she said. “And certainly, duration of use is a factor that we do consider in looking at specific outcomes such as growth, preterm delivery, and risk of serious or opportunistic infections.”

(In the published study of adalimumab, 65.3% of women in the medication-exposed cohort used the medication in all three trimesters, 10.5% in the first and second trimesters, and 22.4% in the first trimester only.)

Women participating in the MotherToBaby studies complete two to four interviews during pregnancy and may be interviewed again after delivery. They are asked for their permission to share a copy of their medical records – and their baby’s medical records – and their babies receive a follow-up pediatric exam by a pediatrician with expertise in dysmorphology/genetics (who is blinded to exposure status), most commonly in the participant’s home. Providers are not asked to enter any data.

Oklahoma Medical Research Foundation

Eliza Chakravarty, MD, a rheumatologist with the Oklahoma Medical Research Foundation in Oklahoma City who treats patients with PsA who are pregnant or considering pregnancy, said that her referrals for research participation “have been mostly to MothertoBaby.”

“Most drug companies [in the autoimmune space] are now contracting with them [for their pregnancy exposure research],” she said. “I really like that it’s become so centralized.”

She tells patients that many questions can be answered through research, that their experience matters, and that “there are benefits” to the extra pediatric examination. “I give them the information and let them decide whether or not they want to call [MotherToBaby],” she said. “I don’t want to impose. I want to make them aware.”

Dr. Chambers emphasizes to patients and physicians that the studies are strictly observational and do not require any changes in personal or medical regimens. “When people hear the word ‘research’ they think of clinical trials. We’re saying, you and your provider do everything you normally would do, just let us observe what happens during your pregnancy.”

Physicians should assure patients, moreover, that “just because the drug is being studied doesn’t mean there’s a known risk or even a suspected risk,” she said.

The MotherToBaby studies receive funding from the pharmaceutical companies, which are required by the Food and Drug Administration to conduct pregnancy exposure registries for medications used during pregnancy or in women of reproductive age. OTIS has an independent advisory board, however, and independently analyzes and publishes its findings. Progress reports are shared with the pharmaceutical companies, and in turn, the FDA, Dr. Chambers said.


To refer patients for MotherToBaby studies, physicians can use an online referral form found on the MothertoBaby web site, a service of OTIS, or call the pregnancy studies team at 877-311-8972 to provide them with the patient’s name or number. Patients may also be given the number and advised to consider calling. MotherToBaby offers medication fact sheets that answer questions about exposures during pregnancy and breastfeeding, and runs a free and confidential teratogen counseling service: 866-626-6847.

OTIS’s MothertoBaby studies are structured as prospective cohort studies. Dr. Chambers, a perinatal epidemiologist, is president of OTIS, which recruits women who have an exposure to the medication under study – at least one dose, for any length of time. And in most cases, it also recruits women with the underlying condition but no exposure and healthy women without the condition to represent the general population.

It’s the disease-matched comparison group that makes OTIS’s studies different from traditional pregnancy registries involving “a simple exposure series and outcomes that are described in the context of what you’d expect in the general population,” said Dr. Chambers, professor in the department of pediatrics, as well as family and preventative medicine, at UCSD and codirector of the Center for Better Beginnings at that university. “Many maternal conditions themselves [or their comorbidities] carry some risk of adverse outcomes in pregnancy.”

The OTIS studies typically involve at least 100 exposed pregnancies and a similar number of unexposed pregnancies; some have cohorts of 200-300.

The recently published study of adalimumab, for instance, included 257 women with exposure to the drug and 120 women in a disease comparison group with no exposure. In addition to finding no associations between drug exposure and adverse outcomes, the study found that women with RA or Crohn’s were at increased risk of preterm delivery, irrespective of adalimumab exposure.

“There’s insufficient [power with any of these numbers] to come to the conclusion that a drug is safe,” she said. “But what we have been able to say [through our studies] is that we’ve looked carefully at the whole array of outcomes ... and we don’t see anything unusual. That early view can be reassuring” until large population-based studies or claims analyses become possible.

Dr. Sammaritano, also with Weill Cornell Medicine, New York, said that she does not recommend registry participation for patients who stop biologics at the diagnosis of pregnancy. Since “the start of IgG antibody transfer during pregnancy is about 16 weeks,” she worries that including these patients might lead to falsely reassuring findings. “We are most interested in [knowing the outcomes of] patients who must continue the drugs through pregnancy,” she said.

Dr. Chambers, however, said that in her view, placental transfer is not a requirement for a medication to have some effect on the outcome of pregnancy. “The outcome could be influenced by an effect of the medication that doesn’t require placental transfer or require placental transfer in large amounts,” she said. “So it’s relevant to examine exposures that have occurred only in the first trimester, and this is especially true for the outcome of major birth defects, most of which are initiated in the first trimester.”

The MotherToBaby studies typically include both early, short exposures and longer exposures, she said. “And certainly, duration of use is a factor that we do consider in looking at specific outcomes such as growth, preterm delivery, and risk of serious or opportunistic infections.”

(In the published study of adalimumab, 65.3% of women in the medication-exposed cohort used the medication in all three trimesters, 10.5% in the first and second trimesters, and 22.4% in the first trimester only.)

Women participating in the MotherToBaby studies complete two to four interviews during pregnancy and may be interviewed again after delivery. They are asked for their permission to share a copy of their medical records – and their baby’s medical records – and their babies receive a follow-up pediatric exam by a pediatrician with expertise in dysmorphology/genetics (who is blinded to exposure status), most commonly in the participant’s home. Providers are not asked to enter any data.

Oklahoma Medical Research Foundation

Eliza Chakravarty, MD, a rheumatologist with the Oklahoma Medical Research Foundation in Oklahoma City who treats patients with PsA who are pregnant or considering pregnancy, said that her referrals for research participation “have been mostly to MothertoBaby.”

“Most drug companies [in the autoimmune space] are now contracting with them [for their pregnancy exposure research],” she said. “I really like that it’s become so centralized.”

She tells patients that many questions can be answered through research, that their experience matters, and that “there are benefits” to the extra pediatric examination. “I give them the information and let them decide whether or not they want to call [MotherToBaby],” she said. “I don’t want to impose. I want to make them aware.”

Dr. Chambers emphasizes to patients and physicians that the studies are strictly observational and do not require any changes in personal or medical regimens. “When people hear the word ‘research’ they think of clinical trials. We’re saying, you and your provider do everything you normally would do, just let us observe what happens during your pregnancy.”

Physicians should assure patients, moreover, that “just because the drug is being studied doesn’t mean there’s a known risk or even a suspected risk,” she said.

The MotherToBaby studies receive funding from the pharmaceutical companies, which are required by the Food and Drug Administration to conduct pregnancy exposure registries for medications used during pregnancy or in women of reproductive age. OTIS has an independent advisory board, however, and independently analyzes and publishes its findings. Progress reports are shared with the pharmaceutical companies, and in turn, the FDA, Dr. Chambers said.


To refer patients for MotherToBaby studies, physicians can use an online referral form found on the MothertoBaby web site, a service of OTIS, or call the pregnancy studies team at 877-311-8972 to provide them with the patient’s name or number. Patients may also be given the number and advised to consider calling. MotherToBaby offers medication fact sheets that answer questions about exposures during pregnancy and breastfeeding, and runs a free and confidential teratogen counseling service: 866-626-6847.
 

With an average age of diagnosis of 28 years, and one of two incidence peaks occurring at 15-30 years, psoriasis affects many women in the midst of their reproductive years. The prospect of pregnancy – or the reality of a surprise pregnancy – drives questions about heritability of the disease in offspring, the impact of the disease on pregnancy outcomes and breastfeeding, and how to best balance risks of treatments with risks of uncontrolled psoriasis and/or psoriatic arthritis (PsA).

While answers to these questions are not always clear, discussions about pregnancy and psoriasis management “shouldn’t be scary,” said Jenny E. Murase, MD, a dermatologist who speaks and writes widely about her research and experience with psoriasis and pregnancy. “We have access to information and data and educational resources to [work with] and reassure our patients – we just need to use it. Right now, there’s unnecessary suffering [with some patients unnecessarily stopping all treatment].”

Much has been learned in the past 2 decades about the course of psoriasis in pregnancy, and pregnancy outcomes data on the safety of biologics during pregnancy are increasingly emerging – particularly for tumor necrosis factor (TNF)–alpha inhibitors.

Ideally, since half of all pregnancies are unplanned, the implications of therapeutic options should be discussed with all women with psoriasis who are of reproductive age, whether they are sexually active or not. “The onus is on us to make sure that we’re considering the possibility [that our patient] could become pregnant without consulting us first,” said Dr. Murase, associate professor of dermatology at the University of California, San Francisco, and director of medical consultative dermatology for the Palo Alto Foundation Medical Group in Mountain View, Calif.

Lisa R. Sammaritano, MD, associate professor of clinical medicine at Weill Cornell Medicine and a rheumatologist at the Hospital for Special Surgery, both in New York, urges similar attention for PsA. “Pregnancy is best planned while patients have quiescent disease on pregnancy-compatible medications,” she said. “We encourage [more] rheumatologists to be actively involved in pregnancy planning [in order] to guide therapy.”

The impact of estrogen

Dr. Murase was inspired to study psoriasis and pregnancy in part by a patient she met as a medical student. “She had severe psoriasis covering her body, and she said that the only times her psoriasis cleared was during her three pregnancies,” Dr. Murase recalled. “I wondered: What about the pregnancies resulted in such a substantial reduction of her psoriasis?”

She subsequently led a study, published in 2005, of 47 pregnant and 27 nonpregnant patients with psoriasis. More than half of the patients – 55% – reported improvements in their psoriasis during pregnancy, 21% reported no change, and 23% reported worsening. Among the 16 patients who had 10% or greater psoriatic body surface area (BSA) involvement and reported improvements, lesions decreased by 84%.

In the postpartum period, only 9% reported improvement, 26% reported no change, and 65% reported worsening. The increased BSA values observed 6 weeks postpartum did not exceed those of the first trimester, suggesting a return to the patients’ baseline status.

Earlier and smaller retrospective studies had also shown that approximately half of patients improve during pregnancy, and it was believed that progesterone was most likely responsible for this improvement. Dr. Murase’s study moved the needle in that it examined BSA in pregnancy and the postpartum period. It also turned the spotlight on estrogen: Patients who had higher levels of improvement also had higher levels of estradiol, estrone, and the ratio of estrogen to progesterone. However, there was no correlation between psoriatic change and levels of progesterone.

To promote fetal survival, pregnancy triggers a shift from Th1 cell–mediated immunity – and Th17 immunity – to Th2 immunity. While there’s no proof of a causative effect, increased estrogen appears to play a role in this shift and in the reduced production of Th1 and Th17 cytokines. Psoriasis is believed to be primarily a Th17-mediated disease, with some Th1 involvement, so this down-regulation can result in improved disease status, Dr. Murase said. (A host of other autoimmune diseases categorized as Th1 mediated similarly tend to improve during pregnancy, she added.)

Information on the effect of pregnancy on PsA is “conflicting,” Dr. Sammaritano said. “Some [of a limited number of studies] suggest a beneficial effect as is generally seen for rheumatoid arthritis. Others, however, have found an increased risk of disease activity during pregnancy ... It may be that psoriatic arthritis can be quite variable from patient to patient in its clinical presentation.”

At least one study, Dr. Sammaritano added, “has shown that the arthritis in pregnancy patients with PsA did not improve, compared to control nonpregnant patients, while the psoriasis rash did improve.”

The mixed findings don’t surprise Dr. Murase. “It harder to quantify joint disease in general,” she said. “And during pregnancy, physiologic changes relating to the pregnancy itself can cause discomfort – your joints ache. The numbers [of improved] cases aren’t as high with PsA, but it’s a more complex question.”

In the postpartum period, however, research findings “all suggest an increased risk of flare” of PsA, Dr. Sammaritano said, just as with psoriasis.
 

Assessing risk of treatment

Understanding the immunologic effects of pregnancy on psoriasis and PsA – and appreciating the concept of a hormonal component – is an important part of treatment decision making. So is understanding pregnancy outcomes data.

Researchers have looked at a host of pregnancy outcomes – including congenital malformations, preterm birth, spontaneous abortion, low birth weight, macrosomia, and gestational diabetes and hypertension – in women with psoriasis or psoriasis/PsA, compared with control groups. Some studies have suggested a link between disease activity and pregnancy complications or adverse pregnancy outcomes, “just as a result of having moderate to severe disease,” while others have found no evidence of increased risk, Dr. Murase said.

“It’s a bit unclear and a difficult question to answer; it depends on what study you look at and what data you believe. It would be nice to have some clarity, but basically the jury is still out,” said Dr. Murase, who, with coauthors Alice B. Gottlieb, MD, PhD, of the department of dermatology at the Icahn School of Medicine at Mount Sinai, New York, and Caitriona Ryan, MD, of the Blackrock Clinic and Charles Institute of Dermatology, University College Dublin, discussed the pregnancy outcomes data in a recently published review of psoriasis in women.

“In my opinion, because we have therapies that are so low risk and well tolerated, it’s better to make sure that the inflammatory cascade and inflammation created by psoriasis is under control,” she said. “So whether or not the pregnancy itself causes the patient to go into remission, or whether you have to use therapy to help the patient stay in remission, it’s important to control the inflammation.”

Contraindicated in pregnancy are oral psoralen, methotrexate, and acitretin, the latter of which should be avoided for several years before pregnancy and “therefore shouldn’t be used in a woman of childbearing age,” said Dr. Murase. Methotrexate, said Dr. Sammaritano, should generally be stopped 1-3 months prior to conception.

For psoriasis, the therapy that’s “classically considered the safest in pregnancy is UVB light therapy, specifically the 300-nm wavelength of light, which works really well as an anti-inflammatory,” Dr. Murase said. Because of the potential for maternal folate degradation with phototherapy and the long-known association of folate deficiency with neural tube defects, women of childbearing age who are receiving light therapy should take daily folic acid supplementation. (She prescribes a daily prenatal vitamin containing at least 1 mg of folic acid for women who are utilizing light therapy.)

Many topical agents can be used during pregnancy, Dr. Murase said. Topical corticosteroids, she noted, have the most safety-affirming data of any topical medication.

Regarding oral therapies, Dr. Murase recommends against the use of apremilast (Otezla) for her patients. “It’s not contraindicated, but the animal studies don’t look promising, so I don’t use that one in women of childbearing age just in case. There’s just very little data to support the safety of this medication [in pregnancy].”

There are no therapeutic guidelines in the United States for guiding the management of psoriasis in women who are considering pregnancy. In 2012, the medical board of the National Psoriasis Foundation published a review of treatment options for psoriasis in pregnant or lactating women, the “closest thing to guidelines that we’ve had,” said Dr. Murase. (Now almost a decade old, the review addresses TNF inhibitors but does not cover the anti-interleukin agents more recently approved for moderate to severe psoriasis and PsA.)

For treating PsA, rheumatologists now have the American College of Rheumatology’s first guideline for the management of reproductive health in rheumatic and musculoskeletal diseases to reference. The 2020 guideline does not address PsA specifically, but its section on pregnancy and lactation includes recommendations on biologic and other therapies used to treat the disease.

Guidelines aside, physician-patient discussions over drug safety have the potential to be much more meaningful now that drug labels offer clinical summaries, data, and risk summaries regarding potential use in pregnancy. The labels have “more of a narrative, which is a more useful way to counsel patients and make risk-benefit decisions” than the former system of five-letter categories, said Dr. Murase. (The changes were made per the Pregnancy and Lactation Labeling Rule of 2015.)

MothertoBaby, a service of the nonprofit Organization of Teratology Information Specialists, also provides good evidence-based information to physicians and mothers, Dr. Sammaritano noted.

The use of biologic therapies

In a 2017 review of biologic safety for patients with psoriasis during pregnancy, Alexa B. Kimball, MD, MPH, professor of dermatology at Harvard Medical School, Boston; Martina L. Porter, MD, currently with the department of dermatology at Beth Israel Deaconess Medical Center, Boston; and Stephen J. Lockwood, MD, MPH, of the department of dermatology at Harvard Medical School, concluded that an increasing body of literature suggests that biologic agents can be used during pregnancy and breastfeeding. Anti-TNF agents “should be considered over IL-12/23 and IL-17 inhibitors due to the increased availability of long-term data,” they wrote.

“In general,” said Dr. Murase, “there’s more and more data coming out from gastroenterology and rheumatology to reassure patients and prescribing physicians that the TNF-blocker class is likely safe to use in pregnancy,” particularly during the first trimester and early second trimester, when the transport of maternal antibodies across the placenta is “essentially nonexistent.” In the third trimester, the active transport of IgG antibodies increases rapidly.

If possible, said Dr. Sammaritano, who served as lead author of the ACR’s reproductive health guideline, TNF inhibitors “will be stopped prior to the third trimester to avoid [the possibility of] high drug levels in the infant at birth, which raises concern for immunosuppression in the newborn. If disease is very active, however, they can be continued throughout the pregnancy.”

The TNF inhibitor certolizumab pegol (Cimzia) has the advantage of being transported only minimally across the placenta, if at all, she and Dr. Murase both explained. “To be actively carried across, antibodies need what’s called an Fc region for the placenta to grab onto,” Dr. Murase said. Certolizumab – a pegylated anti–binding fragment antibody – lacks this Fc region.

Two recent studies – CRIB and a UCB Pharma safety database analysis – showed “essentially no medication crossing – there were barely detectable levels,” Dr. Murase said. Certolizumab’s label contains this information and other clinical trial data as well as findings from safety database analyses/surveillance registries.

“Before we had much data for the biologics, I’d advise transitioning patients to light therapy from their biologics and a lot of times their psoriasis would improve, but it was more of a dance,” she said. “Now we tend to look at [certolizumab] when they’re of childbearing age and keep them on the treatment. I know that the baby is not being immunosuppressed.”

Consideration of the use of certolizumab when treatment with biologic agents is required throughout the pregnancy is a recommendation included in Dr. Kimball’s 2017 review.

As newer anti-interleukin agents – the IL-12/23 and IL-17 inhibitors – play a growing role in the treatment of psoriasis and PsA, questions loom about their safety profile. Dr. Murase and Dr. Sammaritano are waiting for more data. “In general,” Dr. Sammaritano said, “we recommend stopping them at the time pregnancy is detected, based on a lack of data at this time.”

Small-molecule drugs are also less well studied, she noted. “Because of their low molecular weight, we anticipate they will easily cross the placenta, so we recommend avoiding use during pregnancy until more information is available.”

Postpartum care

The good news, both experts say, is that the vast majority of medications, including biologics, are safe to use during breastfeeding. Methotrexate should be avoided, Dr. Sammaritano pointed out, and the impact of novel small-molecule therapies on breast milk has not been studied.

In her 2019 review of psoriasis in women, Dr. Murase and coauthors wrote that too many dermatologists believe that breastfeeding women should either not be on biologics or are uncertain about biologic use during breastfeeding. However, “biologics are considered compatible for use while breastfeeding due to their large molecular size and the proteolytic environment in the neonatal gastrointestinal tract,” they added.

Counseling and support for breastfeeding is especially important for women with psoriasis, Dr. Murase emphasized. “Breastfeeding is very traumatizing to the skin, and psoriasis can form in skin that’s injured. I have my patients set up an office visit very soon after the pregnancy to make sure they’re doing alright with their breastfeeding and that they’re coating their nipple area with some type of moisturizer and keeping the health of their nipples in good shape.”

Timely reviews of therapy and adjustments are also a priority, she said. “We need to prepare for 6 weeks post partum” when psoriasis will often flare without treatment.

Dr. Murase disclosed that she is a consultant for Dermira, UCB Pharma, Sanofi, Ferndale, and Regeneron. She is also coeditor in chief of the International Journal of Women’s Dermatology. Dr. Sammaritano reported that she has no disclosures relating to the treatment of PsA.

With an average age of diagnosis of 28 years, and one of two incidence peaks occurring at 15-30 years, psoriasis affects many women in the midst of their reproductive years. The prospect of pregnancy – or the reality of a surprise pregnancy – drives questions about heritability of the disease in offspring, the impact of the disease on pregnancy outcomes and breastfeeding, and how to best balance risks of treatments with risks of uncontrolled psoriasis and/or psoriatic arthritis (PsA).

Much has been learned in the past 2 decades about the course of psoriasis in pregnancy, and pregnancy outcomes data on the safety of biologics during pregnancy are increasingly emerging – particularly for tumor necrosis factor (TNF)–alpha inhibitors.

Ideally, since half of all pregnancies are unplanned, the implications of therapeutic options should be discussed with all women with psoriasis who are of reproductive age, whether they are sexually active or not. “The onus is on us to make sure that we’re considering the possibility [that our patient] could become pregnant without consulting us first,” said Dr. Murase, associate professor of dermatology at the University of California, San Francisco, and director of medical consultative dermatology for the Palo Alto Foundation Medical Group in Mountain View, Calif.

Lisa R. Sammaritano, MD, associate professor of clinical medicine at Weill Cornell Medicine and a rheumatologist at the Hospital for Special Surgery, both in New York, urges similar attention for PsA. “Pregnancy is best planned while patients have quiescent disease on pregnancy-compatible medications,” she said. “We encourage [more] rheumatologists to be actively involved in pregnancy planning [in order] to guide therapy.”

The impact of estrogen

Dr. Murase was inspired to study psoriasis and pregnancy in part by a patient she met as a medical student. “She had severe psoriasis covering her body, and she said that the only times her psoriasis cleared was during her three pregnancies,” Dr. Murase recalled. “I wondered: What about the pregnancies resulted in such a substantial reduction of her psoriasis?”

She subsequently led a study, published in 2005, of 47 pregnant and 27 nonpregnant patients with psoriasis. More than half of the patients – 55% – reported improvements in their psoriasis during pregnancy, 21% reported no change, and 23% reported worsening. Among the 16 patients who had 10% or greater psoriatic body surface area (BSA) involvement and reported improvements, lesions decreased by 84%.

In the postpartum period, only 9% reported improvement, 26% reported no change, and 65% reported worsening. The increased BSA values observed 6 weeks postpartum did not exceed those of the first trimester, suggesting a return to the patients’ baseline status.

Earlier and smaller retrospective studies had also shown that approximately half of patients improve during pregnancy, and it was believed that progesterone was most likely responsible for this improvement. Dr. Murase’s study moved the needle in that it examined BSA in pregnancy and the postpartum period. It also turned the spotlight on estrogen: Patients who had higher levels of improvement also had higher levels of estradiol, estrone, and the ratio of estrogen to progesterone. However, there was no correlation between psoriatic change and levels of progesterone.

To promote fetal survival, pregnancy triggers a shift from Th1 cell–mediated immunity – and Th17 immunity – to Th2 immunity. While there’s no proof of a causative effect, increased estrogen appears to play a role in this shift and in the reduced production of Th1 and Th17 cytokines. Psoriasis is believed to be primarily a Th17-mediated disease, with some Th1 involvement, so this down-regulation can result in improved disease status, Dr. Murase said. (A host of other autoimmune diseases categorized as Th1 mediated similarly tend to improve during pregnancy, she added.)

Information on the effect of pregnancy on PsA is “conflicting,” Dr. Sammaritano said. “Some [of a limited number of studies] suggest a beneficial effect as is generally seen for rheumatoid arthritis. Others, however, have found an increased risk of disease activity during pregnancy ... It may be that psoriatic arthritis can be quite variable from patient to patient in its clinical presentation.”

At least one study, Dr. Sammaritano added, “has shown that the arthritis in pregnancy patients with PsA did not improve, compared to control nonpregnant patients, while the psoriasis rash did improve.”

The mixed findings don’t surprise Dr. Murase. “It harder to quantify joint disease in general,” she said. “And during pregnancy, physiologic changes relating to the pregnancy itself can cause discomfort – your joints ache. The numbers [of improved] cases aren’t as high with PsA, but it’s a more complex question.”

In the postpartum period, however, research findings “all suggest an increased risk of flare” of PsA, Dr. Sammaritano said, just as with psoriasis.
 

Assessing risk of treatment

Understanding the immunologic effects of pregnancy on psoriasis and PsA – and appreciating the concept of a hormonal component – is an important part of treatment decision making. So is understanding pregnancy outcomes data.

Researchers have looked at a host of pregnancy outcomes – including congenital malformations, preterm birth, spontaneous abortion, low birth weight, macrosomia, and gestational diabetes and hypertension – in women with psoriasis or psoriasis/PsA, compared with control groups. Some studies have suggested a link between disease activity and pregnancy complications or adverse pregnancy outcomes, “just as a result of having moderate to severe disease,” while others have found no evidence of increased risk, Dr. Murase said.

“It’s a bit unclear and a difficult question to answer; it depends on what study you look at and what data you believe. It would be nice to have some clarity, but basically the jury is still out,” said Dr. Murase, who, with coauthors Alice B. Gottlieb, MD, PhD, of the department of dermatology at the Icahn School of Medicine at Mount Sinai, New York, and Caitriona Ryan, MD, of the Blackrock Clinic and Charles Institute of Dermatology, University College Dublin, discussed the pregnancy outcomes data in a recently published review of psoriasis in women.

“In my opinion, because we have therapies that are so low risk and well tolerated, it’s better to make sure that the inflammatory cascade and inflammation created by psoriasis is under control,” she said. “So whether or not the pregnancy itself causes the patient to go into remission, or whether you have to use therapy to help the patient stay in remission, it’s important to control the inflammation.”

Contraindicated in pregnancy are oral psoralen, methotrexate, and acitretin, the latter of which should be avoided for several years before pregnancy and “therefore shouldn’t be used in a woman of childbearing age,” said Dr. Murase. Methotrexate, said Dr. Sammaritano, should generally be stopped 1-3 months prior to conception.

For psoriasis, the therapy that’s “classically considered the safest in pregnancy is UVB light therapy, specifically the 300-nm wavelength of light, which works really well as an anti-inflammatory,” Dr. Murase said. Because of the potential for maternal folate degradation with phototherapy and the long-known association of folate deficiency with neural tube defects, women of childbearing age who are receiving light therapy should take daily folic acid supplementation. (She prescribes a daily prenatal vitamin containing at least 1 mg of folic acid for women who are utilizing light therapy.)

Many topical agents can be used during pregnancy, Dr. Murase said. Topical corticosteroids, she noted, have the most safety-affirming data of any topical medication.

Regarding oral therapies, Dr. Murase recommends against the use of apremilast (Otezla) for her patients. “It’s not contraindicated, but the animal studies don’t look promising, so I don’t use that one in women of childbearing age just in case. There’s just very little data to support the safety of this medication [in pregnancy].”

There are no therapeutic guidelines in the United States for guiding the management of psoriasis in women who are considering pregnancy. In 2012, the medical board of the National Psoriasis Foundation published a review of treatment options for psoriasis in pregnant or lactating women, the “closest thing to guidelines that we’ve had,” said Dr. Murase. (Now almost a decade old, the review addresses TNF inhibitors but does not cover the anti-interleukin agents more recently approved for moderate to severe psoriasis and PsA.)

For treating PsA, rheumatologists now have the American College of Rheumatology’s first guideline for the management of reproductive health in rheumatic and musculoskeletal diseases to reference. The 2020 guideline does not address PsA specifically, but its section on pregnancy and lactation includes recommendations on biologic and other therapies used to treat the disease.

Guidelines aside, physician-patient discussions over drug safety have the potential to be much more meaningful now that drug labels offer clinical summaries, data, and risk summaries regarding potential use in pregnancy. The labels have “more of a narrative, which is a more useful way to counsel patients and make risk-benefit decisions” than the former system of five-letter categories, said Dr. Murase. (The changes were made per the Pregnancy and Lactation Labeling Rule of 2015.)

MothertoBaby, a service of the nonprofit Organization of Teratology Information Specialists, also provides good evidence-based information to physicians and mothers, Dr. Sammaritano noted.

The use of biologic therapies

In a 2017 review of biologic safety for patients with psoriasis during pregnancy, Alexa B. Kimball, MD, MPH, professor of dermatology at Harvard Medical School, Boston; Martina L. Porter, MD, currently with the department of dermatology at Beth Israel Deaconess Medical Center, Boston; and Stephen J. Lockwood, MD, MPH, of the department of dermatology at Harvard Medical School, concluded that an increasing body of literature suggests that biologic agents can be used during pregnancy and breastfeeding. Anti-TNF agents “should be considered over IL-12/23 and IL-17 inhibitors due to the increased availability of long-term data,” they wrote.

“In general,” said Dr. Murase, “there’s more and more data coming out from gastroenterology and rheumatology to reassure patients and prescribing physicians that the TNF-blocker class is likely safe to use in pregnancy,” particularly during the first trimester and early second trimester, when the transport of maternal antibodies across the placenta is “essentially nonexistent.” In the third trimester, the active transport of IgG antibodies increases rapidly.

If possible, said Dr. Sammaritano, who served as lead author of the ACR’s reproductive health guideline, TNF inhibitors “will be stopped prior to the third trimester to avoid [the possibility of] high drug levels in the infant at birth, which raises concern for immunosuppression in the newborn. If disease is very active, however, they can be continued throughout the pregnancy.”

The TNF inhibitor certolizumab pegol (Cimzia) has the advantage of being transported only minimally across the placenta, if at all, she and Dr. Murase both explained. “To be actively carried across, antibodies need what’s called an Fc region for the placenta to grab onto,” Dr. Murase said. Certolizumab – a pegylated anti–binding fragment antibody – lacks this Fc region.

Two recent studies – CRIB and a UCB Pharma safety database analysis – showed “essentially no medication crossing – there were barely detectable levels,” Dr. Murase said. Certolizumab’s label contains this information and other clinical trial data as well as findings from safety database analyses/surveillance registries.

“Before we had much data for the biologics, I’d advise transitioning patients to light therapy from their biologics and a lot of times their psoriasis would improve, but it was more of a dance,” she said. “Now we tend to look at [certolizumab] when they’re of childbearing age and keep them on the treatment. I know that the baby is not being immunosuppressed.”

Consideration of the use of certolizumab when treatment with biologic agents is required throughout the pregnancy is a recommendation included in Dr. Kimball’s 2017 review.

As newer anti-interleukin agents – the IL-12/23 and IL-17 inhibitors – play a growing role in the treatment of psoriasis and PsA, questions loom about their safety profile. Dr. Murase and Dr. Sammaritano are waiting for more data. “In general,” Dr. Sammaritano said, “we recommend stopping them at the time pregnancy is detected, based on a lack of data at this time.”

Small-molecule drugs are also less well studied, she noted. “Because of their low molecular weight, we anticipate they will easily cross the placenta, so we recommend avoiding use during pregnancy until more information is available.”

Postpartum care

The good news, both experts say, is that the vast majority of medications, including biologics, are safe to use during breastfeeding. Methotrexate should be avoided, Dr. Sammaritano pointed out, and the impact of novel small-molecule therapies on breast milk has not been studied.

In her 2019 review of psoriasis in women, Dr. Murase and coauthors wrote that too many dermatologists believe that breastfeeding women should either not be on biologics or are uncertain about biologic use during breastfeeding. However, “biologics are considered compatible for use while breastfeeding due to their large molecular size and the proteolytic environment in the neonatal gastrointestinal tract,” they added.

Counseling and support for breastfeeding is especially important for women with psoriasis, Dr. Murase emphasized. “Breastfeeding is very traumatizing to the skin, and psoriasis can form in skin that’s injured. I have my patients set up an office visit very soon after the pregnancy to make sure they’re doing alright with their breastfeeding and that they’re coating their nipple area with some type of moisturizer and keeping the health of their nipples in good shape.”

Timely reviews of therapy and adjustments are also a priority, she said. “We need to prepare for 6 weeks post partum” when psoriasis will often flare without treatment.

Dr. Murase disclosed that she is a consultant for Dermira, UCB Pharma, Sanofi, Ferndale, and Regeneron. She is also coeditor in chief of the International Journal of Women’s Dermatology. Dr. Sammaritano reported that she has no disclosures relating to the treatment of PsA.

Treatment of psoriasis with biologics was associated with a reduced risk of developing psoriatic arthritis compared with conventional disease-modifying antirheumatic drugs (DMARDs), in a single center retrospective analysis in Argentina that followed patients for almost 2 decades.

About 30%-40% of patients with psoriasis go on to develop psoriatic arthritis (PsA), usually on average about 10 years after the onset of psoriasis. One potential mechanism of PsA onset is through enthesitis, which has been described at subclinical levels in psoriasis.

“It could be speculated that treatment with biologics in patients with psoriasis could prevent the development of psoriatic arthritis, perhaps by inhibiting the subclinical development of enthesitis,” Luciano Lo Giudice, MD, a rheumatology fellow at Hospital Italiano de Buenos Aires, said during his presentation at the virtual annual meeting of the Group for Research and Assessment of Psoriasis and Psoriatic Arthritis.

Although these results do not prove that treatment of the underlying disease delays progression to PsA, it is suggestive, and highlights an emerging field of research, according to Diamant Thaçi, MD, PhD, professor of medicine at University Hospital Schleswig-Holstein, Germany, who led a live discussion following a prerecorded presentation of the results. “We’re going in this direction – how can we prevent psoriatic arthritis, how can we delay it. We are just starting to think about this,” Dr. Thaçi said in an interview.

The researchers examined medical records of 1,626 patients with psoriasis treated at their center between 2000 and 2019, with a total of 15,152 years of follow-up. Of these patients, 1,293 were treated with topical medication, 229 with conventional DMARDs (methotrexate in 77%, cyclosporine in 13%, and both in 10%), and 104 with biologics, including etanercept (34%), secukinumab (20%), adalimumab (20%), ustekinumab (12%), ixekizumab (9%), and infliximab (5%).

They found that 11% in the topical treatment group developed PsA, as did 3.5% in the conventional DMARD group, 1.9% in the biologics group, and 9.1% overall. Treatment with biologics was associated with a significantly lower odds of developing PsA compared with treatment with conventional DMARDs (3 versus 17.2 per 1,000 patient-years; incidence rate ratio [IRR], 0.17; P = .0177). There was a trend toward reduced odds of developing PsA among those on biologic therapy compared with those on topicals (3 versus 9.8 per 1,000 patient-years; IRR, 0.3; P = .0588).

The researchers confirmed all medical encounters using electronic medical records and the study had a long follow-up time, but was limited by the single center and its retrospective nature. It also could not associate reduced risk with specific biologics.

The findings probably reflect the presence of subclinical PsA that many clinicians don’t see, according to Dr. Thaçi. While a dermatology practice might find PsA in 2% or 3%, or at most, 10% of patients with psoriasis, “in our department it’s about 50 to 60 percent of patients who have psoriatic arthritis, because we diagnose it early,” he said.

He found the results of the study encouraging. “It looks like some of the biologics, for example IL [interleukin]-17 or even IL-23 [blockers] may have an influence on occurrence or delay the occurrence of psoriatic arthritis.”

Dr. Thaçi noted that early treatment of skin lesions can increase the probability of longer remissions, especially with IL-23 blockers. Still, that’s no guarantee the same would hold true for PsA risk. “Skin is skin and joints are joints,” Dr. Thaçi said.

Dr. Thaçi and Dr. Lo Giudice had no relevant financial disclosures.

Patients with psoriatic disease are known to be at increased risk of heart failure. A new cohort study suggests that part of the risk may be attributable to the disease itself, not just traditional cardiovascular risk factors like obesity and metabolic abnormalities that are common comorbidities in psoriatic disease. There may also be differences in the risk profiles of patients with ischemic and nonischemic heart failure.

Previous studies have shown that heart failure risk in patients with psoriatic arthritis is 32% higher than in the general population, and with psoriasis, it is 22%-53% higher. However, those studies were based on administrative databases with no clinical information to back up the accuracy of diagnoses, Sahil Koppikar, MD, from the University of Toronto, said during a presentation of the research at the virtual annual meeting of the Group for Research and Assessment of Psoriasis and Psoriatic Arthritis (GRAPPA).

The finding that psoriatic disease inflammation may be a direct risk factor for heart failure might be good news for patients. “By controlling inflammation, we may be able to reduce the risk of heart failure in these patients,” Dr. Koppikar said.

During a question and answer session, discussant Deepak Jadon, MBChB, PhD, director of the rheumatology research unit and lead for psoriatic arthritis at Addenbrooke’s Hospital, Cambridge (England), noted that patients with conditions like lupus and systemic sclerosis may undergo regular echocardiograms, chest CTs, or other surveillance, and asked if Dr. Koppikar could recommend a framework for similar surveillance in psoriatic arthritis.

“With the current data we have, I don’t know if we can make recommendations. What we learned from our study is that patients that have elevated inflammatory disease, with elevated inflammatory markers for a prolonged period of time, were at higher risk than [if they had elevated markers only] just before the event. So poorly controlled patients might be something you should be more aware of, and maybe get cardiology involved. But I don’t think it’s something we should be doing right now for all patients,” Dr. Koppikar said.

The researchers analyzed data from a psoriasis cohort at the University of Toronto that began in 2006. Every 6-12 months, they were assessed by a rheumatologist and underwent imaging assessment and laboratory tests. The primary outcome of the study was the first heart failure event, which the researchers identified by linking the cohort database with provincial hospitalization and mortality databases. They verified all events by examining medical records. They also assessed the association between heart failure and disease activity over time rather than just before the event.

The analysis included 1,994 patients. A total of 64 new heart failure events occurred during a mean follow-up of 11.3 years (2.85 per 1,000 person-years), including 38 ischemic and 26 nonischemic events. A multivariate analysis found that heart failure was associated with adjusted mean (AM) tender joint count (hazard ratio, 1.51; P = .02), AM swollen joint count (HR, 1.82; P = .04), AM erythrocyte sedimentation rate (HR, 1.26; P = .009), AM C-reactive protein (HR, 1.27; P = .001), Health Assessment Questionnaire (HR, 1.95; P = .001), and minimum disease activity state (HR, 0.40; P = .04). The multivariate analysis was adjusted for sex, hypertension, diabetes mellitus, body mass index, ischemic heart disease, lipids, and smoking status.

When the researchers separated the analysis into ischemic and nonischemic heart failure, some interesting associations popped out. Nonischemic heart failure was associated with AM tender joint count (HR, 1.83; P = .004), but ischemic heart failure was not. Other factors associated with nonischemic but not ischemic heart failure included AM swollen joint count (HR, 3.56; P = .0003), damaged joint count (HR, 1.29; P = .04), and pain score (HR, 1.22; P = .047). Minimum disease activity had the opposite result: It was associated with only ischemic heart failure (HR, 0.40; P = .04).

The study cohort more closely resembles a rheumatology cohort than a dermatology cohort, and it suggests that patients with psoriatic arthritis have different cardiovascular comorbidities than those with pure psoriasis, according to Diamant Thaçi, MD, PhD, professor and chairman of the department of dermatology at the University of Lübeck (Germany). “It shows how it important it is to look for comorbidity in the rheumatologic setting,” Dr. Thaçi said in an interview.

The study was supported by the Arthritis Society. Dr. Koppikar and Dr. Thaçi have no relevant financial disclosures.

A new cohort study suggests that part of the risk may be attributable to the disease itself, not just traditional cardiovascular risk factors like obesity and metabolic abnormalities that are common comorbidities in psoriatic disease. There may also be differences in the risk profiles of patients with ischemic and nonischemic heart failure.

Previous studies have shown that heart failure risk in patients with psoriatic arthritis is 32% higher than in the general population, and with psoriasis, it is 22%-53% higher. However, those studies were based on administrative databases with no clinical information to back up the accuracy of diagnoses, Sahil Koppikar, MD, from the University of Toronto, said during a presentation of the research at the virtual annual meeting of the Group for Research and Assessment of Psoriasis and Psoriatic Arthritis (GRAPPA).

The finding that psoriatic disease inflammation may be a direct risk factor for heart failure might be good news for patients. “By controlling inflammation, we may be able to reduce the risk of heart failure in these patients,” Dr. Koppikar said.

During a question and answer session, discussant Deepak Jadon, MBChB, PhD, director of the rheumatology research unit and lead for psoriatic arthritis at Addenbrooke’s Hospital, Cambridge (England), noted that patients with conditions like lupus and systemic sclerosis may undergo regular echocardiograms, chest CTs, or other surveillance, and asked if Dr. Koppikar could recommend a framework for similar surveillance in psoriatic arthritis.

“With the current data we have, I don’t know if we can make recommendations. What we learned from our study is that patients that have elevated inflammatory disease, with elevated inflammatory markers for a prolonged period of time, were at higher risk than [if they had elevated markers only] just before the event. So poorly controlled patients might be something you should be more aware of, and maybe get cardiology involved. But I don’t think it’s something we should be doing right now for all patients,” Dr. Koppikar said.

The researchers analyzed data from a psoriasis cohort at the University of Toronto that began in 2006. Every 6-12 months, they were assessed by a rheumatologist and underwent imaging assessment and laboratory tests. The primary outcome of the study was the first heart failure event, which the researchers identified by linking the cohort database with provincial hospitalization and mortality databases. They verified all events by examining medical records. They also assessed the association between heart failure and disease activity over time rather than just before the event.

The analysis included 1,994 patients. A total of 64 new heart failure events occurred during a mean follow-up of 11.3 years (2.85 per 1,000 person-years), including 38 ischemic and 26 nonischemic events. A multivariate analysis found that heart failure was associated with adjusted mean (AM) tender joint count (hazard ratio, 1.51; P = .02), AM swollen joint count (HR, 1.82; P = .04), AM erythrocyte sedimentation rate (HR, 1.26; P = .009), AM C-reactive protein (HR, 1.27; P = .001), Health Assessment Questionnaire (HR, 1.95; P = .001), and minimum disease activity state (HR, 0.40; P = .04). The multivariate analysis was adjusted for sex, hypertension, diabetes mellitus, body mass index, ischemic heart disease, lipids, and smoking status.

When the researchers separated the analysis into ischemic and nonischemic heart failure, some interesting associations popped out. Nonischemic heart failure was associated with AM tender joint count (HR, 1.83; P = .004), but ischemic heart failure was not. Other factors associated with nonischemic but not ischemic heart failure included AM swollen joint count (HR, 3.56; P = .0003), damaged joint count (HR, 1.29; P = .04), and pain score (HR, 1.22; P = .047). Minimum disease activity had the opposite result: It was associated with only ischemic heart failure (HR, 0.40; P = .04).

The study cohort more closely resembles a rheumatology cohort than a dermatology cohort, and it suggests that patients with psoriatic arthritis have different cardiovascular comorbidities than those with pure psoriasis, according to Diamant Thaçi, MD, PhD, professor and chairman of the department of dermatology at the University of Lübeck (Germany). “It shows how it important it is to look for comorbidity in the rheumatologic setting,” Dr. Thaçi said in an interview.

The study was supported by the Arthritis Society. Dr. Koppikar and Dr. Thaçi have no relevant financial disclosures.
