The case for anti–IL-17 agents as first-line biologics in psoriatic arthritis
LAS VEGAS – 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.

FROM MEDSCAPELIVE LAS VEGAS DERMATOLOGY SEMINAR
Expanded indications likely for apremilast
Big changes are coming in the use of oral apremilast, currently approved for moderate to severe psoriasis and plaque psoriasis in adults, Bruce E. Strober, MD, PhD, predicted at MedscapeLive’s annual Las Vegas Dermatology Seminar, held virtually this year.
“We’ll have , meaning we can use this drug in patients in whom we typically think about using only topical therapies. Keep on the lookout: I think the mild to moderate indication may be coming next year, and that’s going to really shake up the whole landscape of psoriasis therapy,” said Dr. Strober, a dermatologist at Yale University in New Haven, Conn., and Central Connecticut Dermatology in Cromwell, Conn.
Mild or moderate psoriasis
Apremilast manufacturer Amgen has announced positive topline results from the phase 3 ADVANCE trial, a multicenter, placebo-controlled, double-blind, study of 595 patients with mild or moderate psoriasis as defined by an involved body surface area of 2%-15% and a Psoriasis Area and Severity Index score of 2-15. Participants were randomized to the approved dose of apremilast (Otezla) – 30 mg twice daily – or placebo for 16 weeks, followed by 16 weeks of open-label apremilast for all. The full study findings haven’t yet been published or presented at a medical conference, but Amgen announced that the results were positive for all primary and secondary endpoints, and the company plans to file a request with the Food and Drug Administration for an expanded indication for the oral agent.
Pediatric studies
A recently published phase 2, open-label, 1-year study of apremilast in 42 children and adolescents with moderate to severe plaque psoriasis demonstrated that weight-based dosing is the best approach in the pediatric population. The study, which serves as the template for coming phase 3 trials, showed that dosing apremilast at 20 mg twice daily in youths weighing not more than 35 kg and 30 mg twice daily in those who weighed more provided pharmacokinetic exposure similar to that achieved with apremilast at the standard adult dose of 30 mg twice daily. Most participants liked the taste of the tablet.
“My prediction is apremilast will have efficacy in children and teenagers comparable to what it has in adults, with a similar safety and adverse event profile,” Dr. Strober said.
Apremilast works by blocking phosphodiesterase type 4, thereby reducing cyclic AMP metabolism, with a resultant increase in cyclic AMP levels. Cyclic AMP is a regulator of inflammation. Boosting its level has the effect of decreasing tumor necrosis factor and other proinflammatory cytokines while increasing anti-inflammatory mediators, such as interleukin-10.
Dr. Strober characterized apremilast’s efficacy as “modest” by contemporary standards in adults with moderate to severe psoriasis, with week 16 PASI 75 rates of about 30% in randomized trials, compared with 5% in placebo-treated controls. He considers it a good option in patients with moderate disease who are needle phobic and in those averse to the inconvenience of laboratory monitoring. The drug is useful in treating psoriasis in especially challenging locations. Apremilast is specifically approved for scalp psoriasis, and Dr. Strober has anecdotally found it helpful in patients with palmoplantar psoriasis or genital psoriasis.
“Apremilast has tolerability issues: first and foremost diarrhea, nausea, and headache. Probably 15%-20% of patients have nausea or diarrhea ranging from mild to severe, and 1 in 20 have headache. You have to warn patients,” he said.
Roughly 1% of patients experience depressed mood. “I’ve seen it in a few patients. I definitely believe it’s real, so query patients about mood changes while taking apremilast,” the dermatologist advised.
One in 5 patients loses 5% of body weight during the first 6 months on apremilast, but there’s no additional weight loss thereafter. It’s wrong to characterize the oral agent as a weight-loss drug, though, since 80% of patients don’t lose weight, Dr. Strober noted.
Topical PDE-4 inhibitor shows promise
Separately at the Las Vegas meeting, Linda Stein Gold, MD, provided highlights of a phase 2b randomized trial of a topical cream formulation of an extremely potent PDE-4 inhibitor, roflumilast, in patients with chronic plaque psoriasis. This molecule is a couple hundred times more effective at inhibiting the PDE-4 receptor than either oral apremilast or topical crisaborole (Eucrisa). And as a once-daily topical agent with very little systemic absorption, roflumilast cream sidesteps the tolerability issues that accompany apremilast.
“Roflumilast is currently available as an oral formulation for treatment of [chronic obstructive pulmonary disease], so it has a fairly well-established safety profile,” noted Dr. Stein Gold, director of dermatology clinical research at the Henry Ford Health System in Detroit.
The 12-week, multicenter, phase 2b study sponsored by Arcutis Biotherapeutics included 331 patients with chronic plaque psoriasis who were randomized to once-daily 0.3% roflumilast cream, 0.15% roflumilast cream, or vehicle. Three-quarters of participants had baseline moderate disease.
A week-8 Investigator’s Global Assessment (IGA) score of 0 or 1, meaning clear skin or almost clear, plus at least a 2-grade improvement from baseline occurred in 32% of the high-dose roflumilast group, 25% of those on the 0.15% formulation, and 10% of controls. On the secondary endpoint of improvement in tough-to-treat intertriginous psoriasis, at week 12 an intertriginous IGA score of 0 or 1 plus at least a 2-point improvement from baseline was seen in 86% of the 0.3% roflumilast cream group, 50% on low-dose therapy, and 29% of controls. Moreover, the clinical improvements in IGA and itch kicked in quickly, with significant separation from placebo by week 2, Dr. Stein Gold noted.
The phase 3 program is now recruiting participants.
Dr. Strober and Dr. Stein Gold reported receiving research funding from and serving as consultants to Amgen and numerous other pharmaceutical companies.

“Apremilast has tolerability issues: first and foremost diarrhea, nausea, and headache. Probably 15%-20% of patients have nausea or diarrhea ranging from mild to severe, and 1 in 20 have headache. You have to warn patients,” he said.
Roughly 1% of patients experience depressed mood. “I’ve seen it in a few patients. I definitely believe it’s real, so query patients about mood changes while taking apremilast,” the dermatologist advised.
One in 5 patients loses 5% of body weight during the first 6 months on apremilast, but there’s no additional weight loss thereafter. It’s wrong to characterize the oral agent as a weight-loss drug, though, since 80% of patients don’t lose weight, Dr. Strober noted.
Topical PDE-4 inhibitor shows promise
Separately at the Las Vegas meeting, Linda Stein Gold, MD, provided highlights of a phase 2b randomized trial of a topical cream formulation of an extremely potent PDE-4 inhibitor, roflumilast, in patients with chronic plaque psoriasis. This molecule is a couple hundred times more effective at inhibiting the PDE-4 receptor than either oral apremilast or topical crisaborole (Eucrisa). And as a once-daily topical agent with very little systemic absorption, roflumilast cream sidesteps the tolerability issues that accompany apremilast.
“Roflumilast is currently available as an oral formulation for treatment of [chronic obstructive pulmonary disease], so it has a fairly well-established safety profile,” noted Dr. Stein Gold, director of dermatology clinical research at the Henry Ford Health System in Detroit.
The 12-week, multicenter, phase 2b study sponsored by Arcutis Biotherapeutics included 331 patients with chronic plaque psoriasis who were randomized to once-daily 0.3% roflumilast cream, 0.15% roflumilast cream, or vehicle. Three-quarters of participants had baseline moderate disease.
A week-8 Investigator’s Global Assessment (IGA) score of 0 or 1, meaning clear skin or almost clear, plus at least a 2-grade improvement from baseline occurred in 32% of the high-dose roflumilast group, 25% of those on the 0.15% formulation, and 10% of controls. On the secondary endpoint of improvement in tough-to-treat intertriginous psoriasis, at week 12 an intertriginous IGA score of 0 or 1 plus at least a 2-point improvement from baseline was seen in 86% of the 0.3% roflumilast cream group, 50% on low-dose therapy, and 29% of controls. Moreover, the clinical improvements in IGA and itch kicked in quickly, with significant separation from placebo by week 2, Dr. Stein Gold noted.
The phase 3 program is now recruiting participants.

Big changes are coming in the use of oral apremilast, currently approved for moderate to severe psoriasis and plaque psoriasis in adults, Bruce E. Strober, MD, PhD, predicted at MedscapeLive’s annual Las Vegas Dermatology Seminar, held virtually this year.
“We’ll have , meaning we can use this drug in patients in whom we typically think about using only topical therapies. Keep on the lookout: I think the mild to moderate indication may be coming next year, and that’s going to really shake up the whole landscape of psoriasis therapy,” said Dr. Strober, a dermatologist at Yale University in New Haven, Conn., and Central Connecticut Dermatology in Cromwell, Conn.
Mild or moderate psoriasis
Apremilast manufacturer Amgen has announced positive topline results from the phase 3 ADVANCE trial, a multicenter, placebo-controlled, double-blind, study of 595 patients with mild or moderate psoriasis as defined by an involved body surface area of 2%-15% and a Psoriasis Area and Severity Index score of 2-15. Participants were randomized to the approved dose of apremilast (Otezla) – 30 mg twice daily – or placebo for 16 weeks, followed by 16 weeks of open-label apremilast for all. The full study findings haven’t yet been published or presented at a medical conference, but Amgen announced that the results were positive for all primary and secondary endpoints, and the company plans to file a request with the Food and Drug Administration for an expanded indication for the oral agent.
Pediatric studies
A recently published phase 2, open-label, 1-year study of apremilast in 42 children and adolescents with moderate to severe plaque psoriasis demonstrated that weight-based dosing is the best approach in the pediatric population. The study, which serves as the template for coming phase 3 trials, showed that dosing apremilast at 20 mg twice daily in youths weighing not more than 35 kg and 30 mg twice daily in those who weighed more provided pharmacokinetic exposure similar to that achieved with apremilast at the standard adult dose of 30 mg twice daily. Most participants liked the taste of the tablet.
“My prediction is apremilast will have efficacy in children and teenagers comparable to what it has in adults, with a similar safety and adverse event profile,” Dr. Strober said.
Apremilast works by blocking phosphodiesterase type 4, thereby reducing cyclic AMP metabolism, with a resultant increase in cyclic AMP levels. Cyclic AMP is a regulator of inflammation. Boosting its level has the effect of decreasing tumor necrosis factor and other proinflammatory cytokines while increasing anti-inflammatory mediators, such as interleukin-10.
Dr. Strober characterized apremilast’s efficacy as “modest” by contemporary standards in adults with moderate to severe psoriasis, with week 16 PASI 75 rates of about 30% in randomized trials, compared with 5% in placebo-treated controls. He considers it a good option in patients with moderate disease who are needle phobic and in those averse to the inconvenience of laboratory monitoring. The drug is useful in treating psoriasis in especially challenging locations. Apremilast is specifically approved for scalp psoriasis, and Dr. Strober has anecdotally found it helpful in patients with palmoplantar psoriasis or genital psoriasis.

A Review of ACR Convergence Abstracts on Psoriatic Arthritis
New study results from British researchers show that dactylitis may be a clinical indicator of an aggressive phenotype of psoriatic arthritis (PsA). That phenotype is marked by a significantly greater swollen joint count, tender joint count, C-reactive protein, erosive damage, and ultrasound synovitis in very early disease-modifying antirheumatic drug (DMARD)-naive PsA.
The dactylitis study is noted by Dr Saakshi Khattri, assistant professor of rheumatology and dermatology at the Icahn School of Medicine at Mount Sinai, as one of the key findings on PsA presented at ACR Convergence 2020, the American College of Rheumatology's first all-virtual annual meeting. Researchers from Leeds, United Kingdom, concluded that dactylitis may help differentiate risk among patients in an early disease stage.
Another study from researchers in the UK also addresses very early DMARD-naive PsA patients. It found that clinically, swollen joints are linked to power Doppler‒detected synovitis, but tender, nonswollen joints are not.
Also in this ReCAP, Dr Khattri discusses a population-based study from the Mayo Clinic that shows that patients with a family history of psoriasis and severe psoriasis experience a delay in transitioning to PsA. She highlights an interim report about an emerging risk-prediction model that may improve early detection of PsA. Finally, Dr Khattri shares a quality-of-life survey from the National Psoriasis Foundation about the prevalence of unacceptable symptom states in PsA, which reinforces that PsA is far from adequately treated.

TNF inhibitor–induced psoriasis treatment algorithm maintains TNF inhibitor if possible
In a single-center retrospective analysis of 102 patients with psoriasis induced by tumor necrosis factor (TNF) inhibitors, most cases improved or resolved with use of topical medications or with discontinuation of the inciting TNF inhibitor, with or without other interventions. All patients were treated and diagnosed by dermatologists.
While TNF inhibitors have revolutionized management of numerous debilitating chronic inflammatory diseases, they are associated with mild and potentially serious adverse reactions, including de novo psoriasiform eruptions, noted Sean E. Mazloom, MD, and colleagues, at the Cleveland Clinic, Cleveland, Ohio, in the Journal of the American Academy of Dermatology. Despite the fact that it has been more than 15 years since the first reports of TNF inhibitor-induced psoriasis, optimal treatment strategies still remain poorly understood.
IBD and RA most common
Dr. Mazloom and colleagues identified 102 patients (median onset, 41 years; 72.5% female) with TNF inhibitor-induced psoriasis seen at a single tertiary care institution (the Cleveland Clinic) over a 10-year period. The authors proposed a treatment algorithm based on their findings.
Inciting TNF inhibitors were prescribed most commonly for inflammatory bowel disease (IBD) (52%) and rheumatoid arthritis (RA) (24.5%). The most common inciting TNF inhibitor was infliximab (52%). TNF inhibitor-induced psoriasis improved or resolved with topical medications alone in 63.5% of patients, and cyclosporine and methotrexate (10 mg weekly) were often effective (cyclosporine in five of five patients; methotrexate in 7 of 13) if topicals failed.
Noting that the success with topicals in this cohort exceeded that of earlier reports, the authors suggested that more accurate diagnoses and optimal strategies attributable to the involvement of dermatologists may be explanatory.
In 67% of refractory cases, discontinuation of the inciting TNF inhibitor with or without other interventions improved or resolved TNF inhibitor-induced psoriasis. With switching of TNF inhibitors, persistence or worsening of TNF inhibitor-induced psoriasis was reported in 16 of 25 patients (64%).
Algorithm aims at balancing control
The treatment algorithm proposed by Dr. Mazloom and colleagues aims at balancing control of the primary disease with minimization of skin symptom discomfort and continuation of the inciting TNF inhibitor if possible. Only with cyclosporine or methotrexate failure amid severe symptoms and less-than-optimal primary disease control should TNF inhibitors be discontinued and biologics and/or small-molecule inhibitors with alternative mechanisms of action be introduced. Transitioning to other TNF inhibitors may be tried before alternative strategies when the underlying disease is well-controlled but TNF inhibitor-induced psoriasis remains severe.
“Most dermatologists who see TNF-induced psoriasis often are likely already using strategies like the one proposed in the algorithm,” commented senior author Anthony Fernandez, MD, PhD, of the Cleveland (Ohio) Clinic, in an interview. “The concern is over those who may not see TNF inhibitor-induced psoriasis very often, and who may, as a knee-jerk response to TNF-induced psoriasis, stop the inciting medication. When strong side effects occur in IBD and RA, it’s critical to know how well the TNF inhibitor is controlling the underlying disease because lack of control can lead to permanent damage.”
Risk to benefit ratio favors retaining TNF inhibitors
The dermatologist’s goal, if the TNF inhibitor is working well, should be to exhaust all reasonable options to control the psoriasiform eruption and keep the patient on the TNF inhibitor rather than turn to potentially less effective alternatives, Dr. Fernandez added. “The risk:benefit ratio still usually favors adding more immune therapies to treat these reactions in order to enable patients to stay” on their TNF inhibitors.
Study authors disclosed no direct funding for the study. Dr Fernandez, the senior author, receives research funding from Pfizer, Mallinckrodt, and Novartis, consults for AbbVie and Celgene, and is a speaker for AbbVie and Mallinckrodt.

Tildrakizumab for psoriasis shows durable efficacy over 5 years
The full during more than 5,400 patient-years of prospective follow-up, Diamont Thaçi, MD, PhD, reported at the virtual annual congress of the European Academy of Dermatology and Venereology.
For example, 89% of patients who had a PASI-75 response on the 100-mg dose of tildrakizumab (Ilumya) – the dose approved in the United States – at week 28 in the parent reSURFACE 1 and reSURFACE 2 trials maintained their PASI-75 response throughout the next 4½ years in the long-term extension study, as did 93% of those with a week 28 PASI-75 response on 200 mg, a dose approved elsewhere, said Dr. Thaçi, professor of dermatology and director of the Comprehensive Center for Inflammation Medicine at Lübeck (Germany) University.
The same held true for PASI-90, a response achieved by 71% of participants on 100 mg of tildrakizumab at week 28 and 66% at week 244, and by 73% of those on the 200-mg dose at week 28 and 70% at 5 years. A PASI-100 response was documented at week 28 in 29% of patients on the lower dose and 37% of those on 200 mg, with week 244 PASI-100 rates of 33% and 41%, respectively.
The long-term extension study enrolled 622 patients with moderate to severe chronic plaque psoriasis with at least a PASI-75 response to 100 mg or 200 mg of the humanized monoclonal antibody interleukin-23p19 inhibitor at week 28 in reSURFACE 1 or 2, or who were partial or nonresponders to etanercept in reSURFACE 2 and were then switched to tildrakizumab at 200 mg. Five hundred and forty-five of the 622 patients (88%) completed the full 5 years of the extension study.
Very few patients left the study because of loss of efficacy or adverse events. Indeed, the exposure-adjusted rate of drug-related serious adverse events was 0.8 cases per 100 patient-years at tildrakizumab 100 mg and 0.5 per 100 patient-years at 200 mg. Moreover, the rates of drug-related serious adverse events leading to treatment continuation were 0.3 and 0.2 per 100 patient-years at the 100-mg and 200-mg doses. Rates of treatment-emergent severe infection were 1.2 and 1.3 per 100 patient-years on the lower and higher doses. Major adverse cardiovascular events occurred at rates of 0.5 and 0.7 cases per 100 patient-years.
“I think the adverse events are generally similar to what has been seen with other biologics, but slightly less with tildrakizumab. Registries will provide a clearer picture. What’s interesting is that even if you double the dosage you don’t see an increase in side effects,” Dr. Thaçi said.
Asked what happens when a tildrakizumab responder stops taking the monoclonal antibody, he replied, “This is something very interesting we see with the IL-23 inhibitors: The disease comes back very slowly. It takes months, and sometimes years, for the patient to lose the PASI-75 or even the PASI-90 response. But we still consider that continuous treatment is probably the better way to go because we cannot be sure who will lose or regain response. At the moment we don’t have a biomarker to tell us what we should do in our daily practice.”

At the moment we don’t have a biomarker to tell us what we should do in our daily practice.”

The full during more than 5,400 patient-years of prospective follow-up, Diamont Thaçi, MD, PhD, reported at the virtual annual congress of the European Academy of Dermatology and Venereology.
For example, 89% of patients who had a PASI-75 response on the 100-mg dose of tildrakizumab (Ilumya) – the dose approved in the United States – at week 28 in the parent reSURFACE 1 and reSURFACE 2 trials maintained their PASI-75 response throughout the next 4½ years in the long-term extension study, as did 93% of those with a week 28 PASI-75 response on 200 mg, a dose approved elsewhere, said Dr. Thaçi, professor of dermatology and director of the Comprehensive Center for Inflammation Medicine at Lübeck (Germany) University.
The same held true for PASI-90, a response achieved by 71% of participants on 100 mg of tildrakizumab at week 28 and 66% at week 244, and by 73% of those on the 200-mg dose at week 28 and 70% at 5 years. A PASI-100 response was documented at week 28 in 29% of patients on the lower dose and 37% of those on 200 mg, with week 244 PASI-100 rates of 33% and 41%, respectively.
The long-term extension study enrolled 622 patients with moderate to severe chronic plaque psoriasis with at least a PASI-75 response to 100 mg or 200 mg of the humanized monoclonal antibody interleukin-23p19 inhibitor at week 28 in reSURFACE 1 or 2, or who were partial or nonresponders to etanercept in reSURFACE 2 and were then switched to tildrakizumab at 200 mg. Five hundred and forty-five of the 622 patients (88%) completed the full 5 years of the extension study.
Very few patients left the study because of loss of efficacy or adverse events. Indeed, the exposure-adjusted rate of drug-related serious adverse events was 0.8 cases per 100 patient-years at tildrakizumab 100 mg and 0.5 per 100 patient-years at 200 mg. Moreover, the rates of drug-related serious adverse events leading to treatment continuation were 0.3 and 0.2 per 100 patient-years at the 100-mg and 200-mg doses. Rates of treatment-emergent severe infection were 1.2 and 1.3 per 100 patient-years on the lower and higher doses. Major adverse cardiovascular events occurred at rates of 0.5 and 0.7 cases per 100 patient-years.
“I think the adverse events are generally similar to what has been seen with other biologics, but slightly less with tildrakizumab. Registries will provide a clearer picture. What’s interesting is that even if you double the dosage you don’t see an increase in side effects,” Dr. Thaçi said.
Asked what happens when a tildrakizumab responder stops taking the monoclonal antibody, he replied, “This is something very interesting we see with the IL-23 inhibitors: The disease comes back very slowly. It takes months, and sometimes years, for the patient to lose the PASI-75 or even the PASI-90 response. But we still consider that continuous treatment is probably the better way to go because we cannot be sure who will lose or regain response. At the moment we don’t have a biomarker to tell us what we should do in our daily practice.”

FROM THE EADV CONGRESS
Chronic inflammatory diseases vary widely in CHD risk
Not all chronic systemic inflammatory diseases are equal enhancers of atherosclerotic cardiovascular disease risk, according to a large case-control study.
Current AHA/American College of Cardiology guidelines cite three chronic inflammatory diseases as atherosclerotic cardiovascular disease risk enhancers: rheumatoid arthritis, psoriasis, and HIV infection. But this study of those three diseases, along with three others marked by elevated high sensitivity C-reactive protein (systemic sclerosis, inflammatory bowel disease, and systemic lupus erythematosus [SLE]), showed that chronic inflammatory diseases are not monolithic in terms of their associated risk of incident coronary heart disease (CHD).
Indeed, two of the six inflammatory diseases – psoriasis and inflammatory bowel disease – turned out to be not at all associated with increased cardiovascular risk in the 37,117-patient study. The highest-risk disease was SLE, not specifically mentioned in the guidelines, Arjun Sinha, MD, a cardiology fellow at Northwestern University, Chicago, noted in his presentation at the virtual American Heart Association scientific sessions.
The study included 18,129 patients with one of the six chronic inflammatory diseases and 18,988 matched controls, none with CHD at baseline. All regularly received outpatient care at Northwestern during 2000-2019. There were 1,011 incident CHD events during a median of 3.5 years of follow-up.
In a Cox proportional hazards analysis adjusted for demographics, insurance status, hypertension, diabetes, current smoking, total cholesterol, and estimated glomerular filtration rate, here’s how the chronic inflammatory diseases stacked up in terms of incident CHD and MI risks:
- SLE: hazard ratio for CHD, 2.85; for MI, 4.76.
- Systemic sclerosis: HR for CHD, 2.14; for MI, 3.19.
- HIV: HR for CHD, 1.38; for MI, 1.69.
- Rheumatoid arthritis: HR for CHD, 1.22; for MI, 1.45.
- Psoriasis: no significant increase.
- Inflammatory bowel disease: no significant increase.
In an exploratory analysis, Dr. Sinha and coinvestigators evaluated the risk of incident CHD stratified by disease severity. For lack of standardized disease severity scales, the investigators relied upon tertiles of CD4 T cell count in the HIV group and CRP in the others. The HR for new-onset CHD in the more than 5,000 patients with psoriasis didn’t vary by CRP tertile. However, there was a nonsignificant trend for greater disease severity, as reflected by CRP tertile, to be associated with increased incident CHD risk in the HIV and inflammatory bowel disease groups.
In contrast, patients with rheumatoid arthritis or systemic sclerosis who were in the top CRP tertile had a significantly greater risk of developing CHD than that of controls, with HRs of 2.11 in the rheumatoid arthritis group and 4.59 with systemic sclerosis, although patients in the other two tertiles weren’t at significantly increased risk. But all three tertiles of CRP in patients with SLE were associated with significantly increased CHD risk: 3.17-fold in the lowest tertile of lupus severity, 5.38-fold in the middle tertile, and 4.04-fold in the top tertile for inflammation.
These findings could be used in clinical practice to fine-tune atherosclerotic cardiovascular disease risk assessment based upon chronic inflammatory disease type and severity. That’s information which in turn can help guide the timing and intensity of preventive therapy for patients with each disease type.
But studying the association between chronic systemic inflammatory diseases and CHD risk can be useful in additional ways, according to Dr. Sinha. These inflammatory diseases can serve as models of atherosclerosis that shed light on the non–lipid-related mechanisms involved in cardiovascular disease.
“The gradient in risk may be hypothesis-generating with respect to which specific inflammatory pathways may contribute to CHD,” he explained.
Each of these six chronic inflammatory diseases is characterized by a different form of major immune dysfunction, Dr. Sinha continued. A case in point is SLE, the inflammatory disease associated with the highest risk of CHD and MI. Lupus is characterized by a form of neutrophil dysfunction marked by increased formation and reduced degradation of neutrophil extracellular traps, or NETs, as well as by an increase in autoreactive B cells and dysfunctional CD4+ T helper cells. The increase in NETs of of particular interest because NETs have also been shown to contribute to the development of atherosclerosis, endothelial dysfunction, plaque erosion, and thrombosis.
In another exploratory analysis, Dr. Sinha and coworkers found that SLE patients with a neutrophil count above the median level were twice as likely to develop CHD than were those with a neutrophil count below the median.
A better understanding of the upstream pathways linking NET formation in SLE and atherosclerosis could lead to development of new or repurposed medications that target immune dysfunction in order to curb atherosclerosis, said Dr. Sinha, whose study won the AHA’s Samuel A. Levine Early Career Clinical Investigator Award.
He reported having no financial conflicts regarding his study.

Methotrexate users need tuberculosis tests in high-TB areas
People taking even low-dose methotrexate need tuberculosis screening and ongoing clinical care if they live in areas where TB is common, results of a study presented at the virtual annual meeting of the American College of Rheumatology suggest.
Coauthor Carol Hitchon, MD, MSc, a rheumatologist with the University of Manitoba in Winnipeg, who presented the findings, warned that methotrexate (MTX) users who also take corticosteroids or other immunosuppressants are at particular risk and need TB screening.
Current management guidelines for rheumatic disease address TB in relation to biologics, but not in relation to methotrexate, Dr. Hitchon said.
“We know that methotrexate is the foundational DMARD [disease-modifying antirheumatic drug] for many rheumatic diseases, especially rheumatoid arthritis,” Dr. Hitchon noted at a press conference. “It’s safe and effective when dosed properly. However, methotrexate does have the potential for significant liver toxicity as well as infection, particularly for infectious organisms that are targeted by cell-mediated immunity, and TB is one of those agents.”
Using multiple databases, researchers conducted a systematic review of the literature published from 1990 to 2018 on TB rates among people who take less than 30 mg of methotrexate a week. Of the 4,700 studies they examined, 31 fit the criteria for this analysis.
They collected data on tuberculosis incidence or new TB diagnoses vs. reactivation of latent TB infection as well as TB outcomes, such as pulmonary symptoms, dissemination, and mortality.
They found a modest increase in the risk of TB infections in the setting of low-dose methotrexate. In addition, rates of TB in people with rheumatic disease who are treated with either methotrexate or biologics are generally higher than in the general population.
They also found that methotrexate users had higher rates of the type of TB that spreads beyond a patient’s lungs, compared with the general population.
Safety of INH with methotrexate
Researchers also looked at the safety of isoniazid (INH), the antibiotic used to treat TB, and found that isoniazid-related liver toxicity and neutropenia were more common when people took the antibiotic along with methotrexate, but those effects were usually reversible.
TB is endemic in various regions around the world. Historically there hasn’t been much rheumatology capacity in many of these areas, but as that capacity increases more people who are at high risk for developing or reactivating TB will be receiving methotrexate for rheumatic diseases, Dr. Hitchon said.
“It’s prudent for people managing patients who may be at higher risk for TB either from where they live or from where they travel that we should have a high suspicion for TB and consider screening as part of our workup in the course of initiating treatment like methotrexate,” she said.
Narender Annapureddy, MD, a rheumatologist at Vanderbilt University, Nashville, Tenn., who was not involved in the research, pointed out that a limitation of the work is that only 27% of the studies are from developing countries, which are more likely to have endemic TB, and those studies had very few cases.
“This finding needs to be studied in larger populations in TB-endemic areas and in high-risk populations,” he said in an interview.
As for practice implications in the United States, Dr. Annapureddy noted that TB is rare in the United States and most of the cases occur in people born in other countries.
“This population may be at risk for TB and should probably be screened for TB before initiating methotrexate,” he said. “Since biologics are usually the next step, especially in RA after patients fail methotrexate, having information on TB status may also help guide management options after MTX failure.
“Since high-dose steroids are another important risk factor for TB activation,” Dr. Annapureddy continued, “rheumatologists should likely consider screening patients who are going to be on moderate to high doses of steroids with MTX.”

COVID-19 risks in rheumatic disease remain unclear
ACR 2020 studies offer conflicting findings.
Among people with COVID-19, those with systemic autoimmune rheumatic diseases had an elevated 30-day risk of hospitalization, ICU admission, need for mechanical ventilation, and acute kidney injury, compared to a group without rheumatic diseases at 4 months in a match-controlled study.
When investigators expanded the study to 6 months, the difference in need for mechanical ventilation disappeared. However, relative risk for venous thromboembolism (VTE) emerged as 74% higher among people with COVID-19 and with rheumatic disease, said Kristin D’Silva, MD, who presented the findings during a plenary session at the virtual annual meeting of the American College of Rheumatology. She noted that rheumatic disease itself could contribute to VTE risk.
Comorbidities including hypertension, diabetes, and asthma were more common among people with systemic autoimmune rheumatic diseases (SARDs). After adjustment for comorbidities, “the risks of hospitalization and ICU admission were attenuated, suggesting comorbidities are likely key mediators of the increased risk of severe COVID-19 outcomes observed in SARDs patients versus comparators,” Dr. D’Silva, a rheumatology fellow at Massachusetts General Hospital in Boston, said in an interview.
“The risk of venous thromboembolism persisted even after adjusting for comorbidities,” Dr. D’Silva said. Patients with SARDs should be closely monitored for VTE during COVID-19 infection, she added. “Patients with significant cardiovascular, pulmonary, and metabolic comorbidities should be closely monitored for severe COVID-19.”
At the same time, a systematic review of 15 published studies revealed a low incidence of COVID-19 infection among people with rheumatic disease. Furthermore, most experienced a mild clinical course and low mortality, Akhil Sood, MD, said when presenting results of his poster at the meeting.
Underlying immunosuppression, chronic inflammation, comorbidities, and disparities based on racial, ethnic, and socioeconomic status could predispose people with rheumatic disease to poorer COVID-19 outcomes. However, the risks and outcomes of COVID-19 infection among this population “are not well understood,” said Dr. Sood, a second-year resident in internal medicine at the University of Texas Medical Branch in Galveston.
Elevated risks in match-controlled study
Dr. D’Silva and colleagues examined a COVID-19 population and compared 716 people with SARDs and another 716 people from the general public at 4 months, as well as 2,379 people each in similar groups at 6 months. They used real-time electronic medical record data from the TriNetX research network to identify ICD-10 codes for inflammatory arthritis, connective tissue diseases, and systemic vasculitis. They also used ICD-10 codes and positive PCR tests to identify people with COVID-19.
Mean age was 57 years and women accounted for 79% of both groups evaluated at 4 months. Those with SARDs were 23% more likely to be hospitalized (relative risk, 1.23; 95% confidence interval, 1.01-1.50). This group was 75% more likely to be admitted to the ICU (RR, 1.75; 95% CI, 1.11-2.75), 77% more likely to require mechanical ventilation (RR, 1.77; 95% CI, 1.06-2.96), and 83% more likely to experience acute kidney injury (RR, 1.83; 95% CI, 1.11-3.00).
Risk of death was not significantly higher in the SARDs group (RR, 1.16; 95% CI, 0.73-1.86).
When Dr. D’Silva expanded the study to more people at 6 months, they added additional 30-day outcomes of interest: renal replacement therapy, VTE, and ischemic stroke. Risk of need for renal replacement therapy, for example, was 81% higher in the SARDs group (RR, 1.81; 95% CI, 1.07-3.07). Risk of stroke was not significantly different between groups.The improvement in mechanical ventilation risk between 4 and 6 months was not completely unexpected, Dr. D’Silva said. The relative risk dropped from 1.77 to 1.05. “This is not particularly surprising given national trends in the general population reporting decreased severe outcomes of COVID-19 including mortality as the pandemic progresses. This is likely multifactorial including changes in COVID-19 management (such as increasing use of nonintubated prone positioning rather than early intubation and treatments such as dexamethasone and remdesivir), decreased strain on hospitals and staffing compared to the early crisis phase of the pandemic, and higher testing capacity leading to detection of milder cases.”
When the 6-month analysis was further adjusted for comorbidities and a history of prior hospitalization within 1 year, only risk for acute kidney injury and VTE remained significant with relative risks of 1.33 and 1.60, respectively, likely because comorbidities are causal intermediates of COVID-19 30-day outcomes rather than confounders.
When asked to comment on the results, session comoderator Victoria K. Shanmugam, MD, said in an interview that the study “is of great interest both to rheumatologists and to patients with rheumatic disease.”
The higher risk of hospitalization, ICU admission, mechanical ventilation, acute kidney injury, and heart failure “is an important finding with implications for how our patients navigate risk during this pandemic,” said Dr. Shanmugam, director of the division of rheumatology at George Washington University in Washington.
Lower risks emerge in systematic review
The 15 observational studies in the systematic review included 11,815 participants. A total of 179, or 1.5%, tested positive for COVID-19.
“The incidence of COVID-19 infection among patients with rheumatic disease was low,” Dr. Sood said.
Within the COVID-19-positive group, almost 50% required hospitalization, 10% required ICU admission, and 8% died. The pooled event rate for hospitalization was 0.440 (95% CI, 0.296-0.596), while for ICU admission it was 0.132 (95% CI, 0.087-0.194) and for death it was 0.125 (95% CI, 0.082-0.182).
Different calculations of risk
The two studies seem to offer contradictory findings, but the disparities could be explained by study design differences. For example, Dr. D’Silva’s study evaluated a population with COVID-19 and compared those with SARDs versus a matched group from the general public. Dr. Sood and colleagues assessed study populations with rheumatic disease and assessed incidence of SARS-CoV-2 infection and difference in outcomes.
“We are asking very different questions,” Dr. D’Silva said.
“The study by D’Silva et al. was able to account for different factors to reduce confounding,” Dr. Sood said, adding that Dr. D’Silva and colleagues included a high proportion of minorities, compared with a less diverse population in the systematic review, which featured a large number of studies from Italy.
The authors of the two studies had no relevant financial disclosures to report.

ACR 2020 studies offer conflicting findings.
Among people with COVID-19, those with systemic autoimmune rheumatic diseases had an elevated 30-day risk of hospitalization, ICU admission, need for mechanical ventilation, and acute kidney injury, compared to a group without rheumatic diseases at 4 months in a match-controlled study.
When investigators expanded the study to 6 months, the difference in need for mechanical ventilation disappeared. However, relative risk for venous thromboembolism (VTE) emerged as 74% higher among people with COVID-19 and with rheumatic disease, said Kristin D’Silva, MD, who presented the findings during a plenary session at the virtual annual meeting of the American College of Rheumatology. She noted that rheumatic disease itself could contribute to VTE risk.
Comorbidities including hypertension, diabetes, and asthma were more common among people with systemic autoimmune rheumatic diseases (SARDs). After adjustment for comorbidities, “the risks of hospitalization and ICU admission were attenuated, suggesting comorbidities are likely key mediators of the increased risk of severe COVID-19 outcomes observed in SARDs patients versus comparators,” Dr. D’Silva, a rheumatology fellow at Massachusetts General Hospital in Boston, said in an interview.
“The risk of venous thromboembolism persisted even after adjusting for comorbidities,” Dr. D’Silva said. Patients with SARDs should be closely monitored for VTE during COVID-19 infection, she added. “Patients with significant cardiovascular, pulmonary, and metabolic comorbidities should be closely monitored for severe COVID-19.”
At the same time, a systematic review of 15 published studies revealed a low incidence of COVID-19 infection among people with rheumatic disease. Furthermore, most experienced a mild clinical course and low mortality, Akhil Sood, MD, said when presenting results of his poster at the meeting.
Underlying immunosuppression, chronic inflammation, comorbidities, and disparities based on racial, ethnic, and socioeconomic status could predispose people with rheumatic disease to poorer COVID-19 outcomes. However, the risks and outcomes of COVID-19 infection among this population “are not well understood,” said Dr. Sood, a second-year resident in internal medicine at the University of Texas Medical Branch in Galveston.
Elevated risks in match-controlled study
Dr. D’Silva and colleagues examined a COVID-19 population and compared 716 people with SARDs and another 716 people from the general public at 4 months, as well as 2,379 people each in similar groups at 6 months. They used real-time electronic medical record data from the TriNetX research network to identify ICD-10 codes for inflammatory arthritis, connective tissue diseases, and systemic vasculitis. They also used ICD-10 codes and positive PCR tests to identify people with COVID-19.
Mean age was 57 years and women accounted for 79% of both groups evaluated at 4 months. Those with SARDs were 23% more likely to be hospitalized (relative risk, 1.23; 95% confidence interval, 1.01-1.50). This group was 75% more likely to be admitted to the ICU (RR, 1.75; 95% CI, 1.11-2.75), 77% more likely to require mechanical ventilation (RR, 1.77; 95% CI, 1.06-2.96), and 83% more likely to experience acute kidney injury (RR, 1.83; 95% CI, 1.11-3.00).
Risk of death was not significantly higher in the SARDs group (RR, 1.16; 95% CI, 0.73-1.86).
When Dr. D’Silva expanded the study to more people at 6 months, they added additional 30-day outcomes of interest: renal replacement therapy, VTE, and ischemic stroke. Risk of need for renal replacement therapy, for example, was 81% higher in the SARDs group (RR, 1.81; 95% CI, 1.07-3.07). Risk of stroke was not significantly different between groups.The improvement in mechanical ventilation risk between 4 and 6 months was not completely unexpected, Dr. D’Silva said.

Topical tapinarof effective in pivotal psoriasis trials
in two identical pivotal phase 3, randomized trials, Mark G. Lebwohl, MD, reported at the virtual annual congress of the European Academy of Dermatology and Venereology.
“Tapinarof cream has the potential to be a first-in-class topical therapeutic aryl hydrocarbon receptor modulating agent and will provide physicians and patients with a novel nonsteroidal topical treatment option that’s effective and well tolerated,” predicted Dr. Lebwohl, professor and chair of the department of dermatology at the Icahn School of Medicine at Mount Sinai, New York.
Dermavant Sciences, the company developing topical tapinarof for treatment of atopic dermatitis as well as psoriasis, announced that upon completion of an ongoing long-term extension study the company plans to file for approval of the drug for psoriasis in 2021.
The two pivotal phase 3 trials, PSOARING 1 and PSOARING 2, randomized a total of 1,025 patients with plaque psoriasis to once-daily tapinarof cream 1% or its vehicle. “This was a fairly difficult group of patients,” Dr. Lebwohl said. Roughly 80% had moderate psoriasis as defined by a baseline Physician Global Assessment (PGA) score of 3, with the remainder split evenly between mild and severe disease. Participants averaged 8% body surface area involvement. Body mass index was on average greater than 31 kg/m2.
The primary efficacy endpoint was a PGA score of 0 or 1 – that is, clear or almost clear – plus at least a 2-grade improvement in PGA from baseline at week 12. This was achieved in 35.4% of patients on tapinarof cream once daily in PSOARING 1 and 40.2% in PSOARING 2, compared with 6.0% and 6.3% of vehicle-treated controls, a highly significant difference (both P < .0001).
The prespecified secondary endpoint was a 75% improvement in Psoriasis Area and Severity Index (PASI) score from baseline to week 12. The PASI 75 rates were 36.1% and 47.6% with tapinarof, significantly better than the 10.2% and 6.9% rates in controls.
The most common adverse event associated with tapinarof was folliculitis, which occurred in 20.6% of treated patients in PSOARING 1 and in 15.7% in PSOARING 2. More than 98% of cases were mild or moderate. The folliculitis led to study discontinuation in only 1.8% and 0.9% of subjects in the two trials.
The other noteworthy adverse event was contact dermatitis. It occurred in 3.8% and 4.7% of tapinarof-treated patients, again with low study discontinuation rates of 1.5% and 2.2%.
During the audience discussion, Linda Stein Gold, MD, lead investigator for PSOARING 2, was asked about this folliculitis. She said the mechanism is unclear, as is the best management. She encountered it in patients, didn’t treat it, and it went away on its own. It’s not a bacterial folliculitis; when cultured it invariably proved culture negative, she noted.
The comparative efficacy of tapinarof cream versus the potent and superpotent topical corticosteroids commonly used in the treatment of psoriasis hasn’t been evaluated in head-to-head studies. Her experience and that of the other investigators has been that tapinarof’s efficacy is comparably strong, “but we don’t have the steroid side effects,” said Dr. Stein Gold, director of dermatology clinical research at Henry Ford Health System in Detroit.
In an interview, Dr. Lebwohl said tapinarof, if approved, could help meet a major unmet need for new and better topical therapies for psoriasis.
“You keep hearing about all these biologic agents and small-molecule pills coming out, but the majority of patients still only need topical therapy,” he observed.
Moreover, even when patients with more severe disease achieve a PASI 75 or PASI 90 response with systemic therapy, they usually still need supplemental topical therapy to get them closer to the goal of clear skin.
The superpotent steroids that are the current mainstay of topical therapy come with predictable side effects that dictate a 2- to 4-week limit on their approved use. Also, they’re not supposed to be applied to the face or to intertriginous sites, including the groin, axillae, and under the breasts. In contrast, tapinarof has proved safe and effective in these sensitive areas.
Asked to predict how tapinarof is likely to be used in clinical practice, Dr. Lebwohl replied: “The efficacy was equivalent to strong topical steroids, so I think it could be used first line in place of topical steroids. And in particular, in patients with psoriasis at facial and intertriginous sites, I think an argument can be made for insisting that it be first line.”
He also expects that physicians will end up utilizing tapinarof for a varied group of steroid-responsive dermatoses beyond psoriasis and atopic dermatitis.
“It clearly reduces inflammation, which is why I would expect it would work well for those,” the dermatologist said.
The mechanism of action of tapinarof has been worked out. The drug enters the cell and binds to the aryl hydrocarbon receptor, forming a complex that enters the nucleus. There it joins with the aryl hydrocarbon receptor nuclear translocator, which regulates gene expression so as to reduce production of inflammatory cytokines while promoting an increase in skin barrier proteins, which is why tapinarof is also being developed as an atopic dermatitis therapy.
Dr. Lebwohl and Dr. Stein Gold reported receiving research funds from and serving as consultants to Dermavant Sciences as well as numerous other pharmaceutical companies.

FROM THE EADV CONGRESS
Biologics may protect psoriasis patients against severe COVID-19
presented at the virtual annual congress of the European Academy of Dermatology and Venereology.
“Biologics seem to be very protective against severe, poor-prognosis COVID-19, but they do not prevent infection with the virus,” reported Giovanni Damiani, MD, a dermatologist at the University of Milan.
This apparent protective effect of biologic agents against severe and even fatal COVID-19 is all the more impressive because the psoriasis patients included in the Italian study – as is true of those elsewhere throughout the world – had relatively high rates of obesity, smoking, and chronic obstructive pulmonary disease, known risk factors for severe COVID-19, he added.
He presented a case-control study including 1,193 adult psoriasis patients on biologics or apremilast (Otezla) at Milan’s San Donato Hospital during the period from Feb. 21 to April 9, 2020. The control group comprised more than 10 million individuals, the entire adult population of the Lombardy region, of which Milan is the capital. This was the hardest-hit area in all of Italy during the first wave of COVID-19.
Twenty-two of the 1,193 psoriasis patients experienced confirmed COVID-19 during the study period. Seventeen were quarantined at home because their disease was mild. Five were hospitalized. But no psoriasis patients were placed in intensive care, and none died.
Psoriasis patients on biologics were significantly more likely than the general Lombardian population to test positive for COVID-19, with an unadjusted odds ratio of 3.43. They were at 9.05-fold increased risk of home quarantine for mild disease, and at 3.59-fold greater risk than controls for hospitalization for COVID-19. However, they were not at significantly increased risk of ICU admission. And while they actually had a 59% relative risk reduction for death, this didn’t achieve statistical significance.
Forty-five percent of the psoriasis patients were on an interleukin-17 (IL-17) inhibitor, 22% were on a tumor necrosis factor–alpha inhibitor, and 20% were taking an IL-12/23 inhibitor. Of note, none of 77 patients on apremilast developed COVID-19, even though it is widely considered a less potent psoriasis therapy than the injectable monoclonal antibody biologics.
The French experience
Anne-Claire Fougerousse, MD, and her French coinvestigators conducted a study designed to address a different question: Is it safe to start psoriasis patients on biologics or older conventional systemic agents such as methotrexate during the pandemic?
She presented a French national cross-sectional study of 1,418 adult psoriasis patients on a biologic or standard systemic therapy during a snapshot in time near the peak of the first wave of the pandemic in France: the period from April 27 to May 7, 2020. The group included 1,188 psoriasis patients on maintenance therapy and 230 who had initiated systemic treatment within the past 4 months. More than one-third of the patients had at least one risk factor for severe COVID-19.
Although testing wasn’t available to confirm all cases, 54 patients developed probable COVID-19 during the study period. Only five required hospitalization. None died. The two hospitalized psoriasis patients admitted to an ICU had obesity as a risk factor for severe COVID-19, as did another of the five hospitalized patients, reported Dr. Fougerousse, a dermatologist at the Bégin Military Teaching Hospital in Saint-Mandé, France. Hospitalization for COVID-19 was required in 0.43% of the French treatment initiators, not significantly different from the 0.34% rate in patients on maintenance systemic therapy. A study limitation was the lack of a control group.
Nonetheless, the data did answer the investigators’ main question: “This is the first data showing no increased incidence of severe COVID-19 in psoriasis patients receiving systemic therapy in the treatment initiation period compared to those on maintenance therapy. This may now allow physicians to initiate conventional systemic or biologic therapy in patients with severe psoriasis on a case-by-case basis in the context of the persistent COVID-19 pandemic,” Dr. Fougerousse concluded.
Proposed mechanism of benefit
The Italian study findings that biologics boost the risk of infection with the SARS-CoV-2 virus in psoriasis patients while potentially protecting them against ICU admission and death are backed by a biologically plausible albeit as yet unproven mechanism of action, Dr. Damiani asserted.
He elaborated: A vast body of high-quality clinical trials data demonstrates that these targeted immunosuppressive agents are associated with modestly increased risk of viral infections, including both skin and respiratory tract infections. So there is no reason to suppose these agents would offer protection against the first phase of COVID-19, involving SARS-CoV-2 infection, nor protect against the second (pulmonary phase), whose hallmarks are dyspnea with or without hypoxia. But progression to the third phase, involving hyperinflammation and hypercoagulation – dubbed the cytokine storm – could be a different matter.
“Of particular interest was that our patients on IL-17 inhibitors displayed a really great outcome. Interleukin-17 has procoagulant and prothrombotic effects, organizes bronchoalveolar remodeling, has a profibrotic effect, induces mitochondrial dysfunction, and encourages dendritic cell migration in peribronchial lymph nodes. Therefore, by antagonizing this interleukin, we may have a better prognosis, although further studies are needed to be certain,” Dr. Damiani commented.
Publication of his preliminary findings drew the attention of a group of highly respected thought leaders in psoriasis, including James G. Krueger, MD, head of the laboratory for investigative dermatology and codirector of the center for clinical and investigative science at Rockefeller University, New York.
The Italian report prompted them to analyze data from the phase 4, double-blind, randomized ObePso-S study investigating the effects of the IL-17 inhibitor secukinumab (Cosentyx) on systemic inflammatory markers and gene expression in psoriasis patients. The investigators demonstrated that IL-17–mediated inflammation in psoriasis patients was associated with increased expression of the angiotensin-converting enzyme 2 (ACE2) receptor in lesional skin, and that treatment with secukinumab dropped ACE2 expression to levels seen in nonlesional skin. Given that ACE2 is the chief portal of entry for SARS-CoV-2 and that IL-17 exerts systemic proinflammatory effects, it’s plausible that inhibition of IL-17–mediated inflammation via dampening of ACE2 expression in noncutaneous epithelia “could prove to be advantageous in patients with psoriasis who are at risk for SARS-CoV-2 infection,” according to Dr. Krueger and his coinvestigators in the Journal of Allergy and Clinical Immunology.
Dr. Damiani and Dr. Fougerousse reported having no financial conflicts regarding their studies. The secukinumab/ACE2 receptor study was funded by Novartis.
