Hope shines bright for hidradenitis suppurativa treatments
in separate trials.
Around 40%-50% of patients exhibited a clinical response to these agents at 16 weeks, a leading HS expert reported at the annual congress of the European Academy of Dermatology and Venereology.
Time in the spotlight for HS
Research into HS is “an incredibly active field at this moment,” said Alexa B. Kimball, MD, MPH, professor of dermatology, Harvard Medical School, and president and chief executive officer of Harvard Medical Faculty Physicians at Beth Israel Deaconess Medical Center, Boston.
It’s “been great for advancing our understanding of the biology and the treatments that we will be able to use,” she said.
During the late-breaking sessions at the annual EADV Congress, Dr. Kimball presented data from two trials – SUNSHINE and SUNRISE – that investigated the efficacy, safety and tolerability of the interleukin (IL) 17A inhibitor secukinumab (Cosentyx) versus placebo in the treatment of moderate to severe HS.
“This is only the second phase 3 program we have ever seen in HS and the first one since 2016,” Dr. Kimball said of the trials. It’s also the largest trial program in HS conducted to date, she added, “so it really is a milestone.”
The last big development was when adalimumab, a tumor necrosis factor (TNF) blocker, gained regulatory approval for HS in 2016, observed Neil Patel, PhD, MRCP, who leads the HS service at Imperial College Healthcare NHS Trust in London.
“Adalimumab has been very helpful for many patients, but not all patients respond, and others may respond initially but then the treatment starts to fail after a year or 2,” Dr. Patel said in an interview with this news organization.
“There is definitely a huge need for alternative medication for this condition, which still has a lack of effective treatment options,” added Dr. Patel, who was not involved in either of the studies.
“One major upside for secukinumab is that its safety profile is generally very good and familiarity in the dermatologic community is already well established,” Christopher Sayed, MD, said in a separate interview.
“This will make most providers very comfortable offering it as a potential treatment option sooner rather than later given that its efficacy has now been demonstrated in phase 3 trials,” added Dr. Sayed, associate professor of dermatology at the University of North Carolina at Chapel Hill.
Two identically designed trials
Altogether, SUNSHINE and SUNRISE enrolled just over 1,000 patients at 219 sites in 33 countries. Both trials were identical in their design: A 4-week run-in phase before a randomized, double-blind treatment phase that tested two dosing regimens of secukinumab (300 mg administered subcutaneously) every 2 or 4 weeks vs. placebo for 16 weeks. The trial continued after this time, with patients in the placebo arm re–randomly assigned to treatment with one of the two secukinumab regimens out to a year.
The primary endpoint was the percentage of patients achieving a Hidradenitis Suppurativa Clinical Response (HiSCR) after 16 weeks of treatment, with key secondary endpoints, which were abscess and inflammatory nodule (AN) count, occurrence of flares, and at least a 30% reduction in Patient’s Global Assessment of Skin Pain assessed using a numeric rating scale (NPRS30).
Secukinumab superior to placebo
The HiSCR is defined as at least a 50% decrease in AN count with no increase in the number of abscesses or in the number of draining fistulas relative to baseline. This was achieved by about 42%-45% of patients who received secukinumab every 2 weeks, about 42%-46% of those who received secukinumab every 4 weeks, and about 31%-33% of those on placebo in both studies.
Of note, fewer patients treated with secukinumab (about 15%-20% among those treated every 2 weeks, and about 15% to 23% among those treated every 4 weeks) than those on placebo (27%-29%) experienced flares, defined as at least a 25% increase in AN count and at least a two-point increase relative to baseline values.
Improvement in HS pain can be a difficult parameter to meet, Dr. Kimball noted. “Pain is such an important feature of this disease as it so debilitating for the patients.” More than one-third (almost 36%-39%) of patients given secukinumab vs. just over a quarter (26.9%) given placebo achieved at least a 30% reduction in NPRS30 ratings, she reported. The difference between active and placebo treatment was significant only when secukinumab was given every 2 weeks, however.
“The placebo rates that we see in these studies are exactly parallel to what we saw in other studies, and other disease states when we had a 50% bar of improvement,” Dr. Kimball said when questioned about these results.
“HS is a highly variable disease; it’s maybe not so much the placebo rate or the scoring system used but maybe the 50% bar set for improvement is too low. It’s likely, as data start to mature and a 75% HiSCR can be calculated, that the placebo rates will drop,” she said.
There were no surprises when it came to the safety of secukinumab, being an old player in a new game, she noted. It was “well tolerated” and tolerability was “consistent with the known safety profile,” Dr. Kimball said, “so we expect it to be a new, safe, and effective add to our armamentarium in treating this disease.”
This research involves “basically borrowing drugs from other areas and trying them in HS to see what effect they may have,” Dr. Patel said, noting that drugs such as adalimumab and secukinumab already had a proven track record in other diseases, such as psoriasis. “These early data for secukinumab definitely are very exciting, but we would need to see real-life results” in patients with HS who are not enrolled in trials to see the benefits, he added.
‘Tipping point’ for HS research
“I think we will look back on this meeting and realize that it was an incredibly important tipping point for the treatment of this incredibly debilitating disease,” Dr. Kimball said.
Elsewhere at the meeting, she had presented findings from a phase 2a study that pitted three different kinase inhibitors with different modes of action against each other and compared them with placebo.
The three agents evaluated are an IL-1 receptor–associated kinase 4 inhibitor known as PF-06650833, a tyrosine kinase 2 (TYK2) JAK1 inhibitor brepocitinib, and the TYK2 inhibitor PF-06826647.
“This technique has been used in oncology,” Dr. Kimball said, noting that the ability to test multiple drugs at the same time “means we can really much more efficiently test two different things at the same time, and also put fewer patients at risk for potential problems if drugs don’t work.”
Positive signs for brepocitinib, not the other kinases tested
The results showed that though brepocitinib worked in HS, the other two novel compounds did not appear to have beneficial effects. Just over half (52%) of the 52 patients treated with brepocitinib achieved an HiSCR at 16 weeks, compared with around one-third of those given placebo, PF-06650833, or PF-06826647.
A similar benefit was seen in terms of reduction in flares for brepocitinib but not the other agents, although there was no difference between them all in terms of NPRS30 pain reduction.
“We’ve been able to test three different modalities. This tells us some things about the pathophysiology for HS, which is a very profoundly intensive inflammatory process,” which, Dr. Kimball said, “may require multiple modalities of action to get it under control.” In addition, these “general modalities seem to safe and well tolerated,” she added.
Take-homes for practice and future research
“While it is disappointing that two of the drugs tested did not clearly demonstrate efficacy, it is very possible that these mechanisms of action may be successful targets in the future as new dosing strategies and drugs targeting these pathways are developed,” Dr. Sayed said.
A case in point, he added, was that “adalimumab did not meet treatment endpoints at a dose of 40 mg every other week, but clearly has made a major impact at 40 mg weekly.”
The bottom line is that “both secukinumab and beprocitinib demonstrated efficacy over placebo and are likely to be helpful for a significant number of patients with HS,” Dr. Sayed said. “Hopefully, we’ll see head-to-head trials and more data regarding proportions of patients with deeper responses using criteria such as HiSCR75 and HiSCR90.”
Moreover, “having a larger number of drugs with a range of mechanisms of action is extraordinarily helpful given how difficult the disease can be to manage. We will hopefully continue to see creative approaches and further successes in the current wave of phase 1, 2, and 3 trials that are already underway.”
The SUNSHINE and SUNRISE studies were funded by Novartis Pharma AG, Basel, Switzerland. The phase 2A study Dr. Kimball presented was sponsored by Pfizer.
Dr. Kimball disclosed ties to both Novartis and Pfizer and acts as a consultant and investigator to AbbVie, Bristol-Myers Squibb, Janssen, Eli Lilly, Novartis, and UCB. She is an investigator for Incyte and AnaptysBio; acts as a consultant to Bayer, Boehringer Ingelheim, Ventyz, Moonlake, Lily, Concert, EvoImmune, Sonoma Bio, and Sanofi; receives fellowship funding from Janssen, and serves on the Board of Directors for Almirall.
Dr. Patel had no conflicts of interest to disclose. Dr. Sayed is the director of the HS Foundation, a nonprofit organization, and has acted as an adviser or consultant to, speaker for, and received research funding from multiple drug companies including AbbVie, ChemoCentryx, Incyte, InflaRx, Novartis, and UCB.

FROM THE EADV CONGRESS
Pandemic has helped clinicians to gain better insight on pernio, expert says
PORTLAND, ORE. – while others are not, according to Lindy P. Fox, MD, professor of dermatology and director of the hospital consultation service at the University of California, San Francisco.
“We’re learning a lot about pernio because of COVID,” Dr. Fox, a member of the American Academy of Dermatology’s Ad Hoc Task Force on COVID-19, said at the annual meeting of the Pacific Dermatologic Association. “Patients with pernio tend to either have bright red or purple individual lesions or an erythromelalgia-like presentation, often waking up in the middle of the night saying ‘my feet hurt. I can’t put sheets over my feet.’ In my experience, the patients with an erythromelalgia-like presentation tend to be a lot harder to treat.”
Establishing terminology to describe pernio-like lesions was a challenge in the early stages of the COVID-19 pandemic, Dr. Fox added, with clinicians using terms like erythema multiforme-like, coxsackie-like, or even necrotic to describe the lesions. “I don’t think pernio is truly necrotic; I think it’s really inflammatory and purpuric,” she said.
Early in the pandemic, studies suggesting a link with these cases and COVID-19 infection include a case series of 318 patients with pernio-like skin lesions who had confirmed or suspected COVID-19. Most of these patients were generally young and healthy and most had relatively mild COVID-19; 7% were laboratory-confirmed COVID-19 positive, and 6% were close contacts of patients with confirmed COVID-19. Pernio-like lesions were the only symptoms in 55% of the patients.
In another study, researchers in France evaluated the clinical, laboratory, and pathologic characteristics of 40 patients who developed chilblain-like lesions (mostly involving the toes) during the COVID-19 pandemic and were seen as outpatients in April 2020 . All were polymerase chain reaction (PCR) negative, 30% were SARS-CoV-2 serology positive, and 60% had elevated D-dimers. Histology obtained from 19 of the patients revealed lymphocytic inflammation and vascular damage, and 8 had IgA positivity.
In a retrospective analysis of seven pediatric chilblains cases during the pandemic, researchers examined the skin biopsies to evaluate histopathological features and explored the presence of SARS-CoV-2 in the tissue. All patients were PCR negative. The authors observed cytoplasmic granular positivity for SARS-CoV-2 spike protein in endothelial cells, a feature that they said showed coronavirus-like particles, consistent with SARS-CoV-2.
Not all studies in the medical literature have demonstrated an association between pernio-like/chilblains-like lesions and COVID-19, though. An analysis of 23 patients, with skin eruptions considered associated with SARS-CoV-2 infections (including 21 cases of chilblains) during the first wave of the pandemic found that the antibody and T-cell response in patients with pandemic chilblains was the same as in negative controls.
“What’s remarkably interesting about this study is that they did autopsies of samples from patients who had died prepandemic, so there was no such thing as COVID-19,” said Dr. Fox, who was not involved with the study. “They stained for viral particles in those patients, and they were positive in a subset of patients. This makes me wonder about what the significance of that staining positivity is.”
Yet another group of investigators looked at what was happening with pernio during the waves of COVID in a study of chilblains cases in children in Spain, and found a stronger association between lockdown and cold temperature, which argues against a direct association between pernio and COVID infection.
In Dr. Fox’s experience, COVID toes can recur, especially upon exposure to cold. “What taught me this in real life is a patient who I saw remotely by video,” she recalled. “It was early on in the pandemic. I could not prove he had COVID no matter how hard I tried, but I do think he had COVID toes at that time.” When he later was confirmed to have COVID, “he got pernio in the same exact location as his original suspected COVID toes.”
According to an analysis of long COVID in the skin, based on cases reported to the American Academy of Dermatology–International League of Dermatological Societies registry from April 8 to Oct. 8, 2020, pernio-like lesions lasted a median of 12 days in patients with lab-confirmed COVID-19 and a median of 15 days in those with suspected COVID-19. But almost 7% of the 103 pernio cases were long-haulers, defined as those with dermatologic signs of COVID that lasted beyond 60 days.
“There are some patients who are resistant to treatment,” Dr. Fox said. “In addition, recurrent lesions make me think that maybe all pernio is triggered by some viral cause. This causes an immunologic phenomenon that’s responding to a viral trigger you’re trying to deal with. That may be the better way to think about COVID toes.”
Different variants of COVID also appear to be changing the characteristics of dermatologic manifestations associated with infection. Results from a large retrospective analysis of nearly 350,000 users of a COVID study App in the United Kingdom found that skin lesions were more predictive of a positive test in the Delta wave, compared with the Omicron wave, while pernio-like lesions were predictive of infection in the Delta wave but not in the Omicron wave.
“And, whether you were vaccinated or unvaccinated really did not influence whether or not you were going to have a skin rash as a presenting sign of COVID, except for the burning rash, which was less in vaccinated patients,” said Dr. Fox, who was not involved with the study.
Dr. Fox reported having no relevant disclosures.
PORTLAND, ORE. – while others are not, according to Lindy P. Fox, MD, professor of dermatology and director of the hospital consultation service at the University of California, San Francisco.
“We’re learning a lot about pernio because of COVID,” Dr. Fox, a member of the American Academy of Dermatology’s Ad Hoc Task Force on COVID-19, said at the annual meeting of the Pacific Dermatologic Association. “Patients with pernio tend to either have bright red or purple individual lesions or an erythromelalgia-like presentation, often waking up in the middle of the night saying ‘my feet hurt. I can’t put sheets over my feet.’ In my experience, the patients with an erythromelalgia-like presentation tend to be a lot harder to treat.”
Establishing terminology to describe pernio-like lesions was a challenge in the early stages of the COVID-19 pandemic, Dr. Fox added, with clinicians using terms like erythema multiforme-like, coxsackie-like, or even necrotic to describe the lesions. “I don’t think pernio is truly necrotic; I think it’s really inflammatory and purpuric,” she said.
Early in the pandemic, studies suggesting a link with these cases and COVID-19 infection include a case series of 318 patients with pernio-like skin lesions who had confirmed or suspected COVID-19. Most of these patients were generally young and healthy and most had relatively mild COVID-19; 7% were laboratory-confirmed COVID-19 positive, and 6% were close contacts of patients with confirmed COVID-19. Pernio-like lesions were the only symptoms in 55% of the patients.
In another study, researchers in France evaluated the clinical, laboratory, and pathologic characteristics of 40 patients who developed chilblain-like lesions (mostly involving the toes) during the COVID-19 pandemic and were seen as outpatients in April 2020 . All were polymerase chain reaction (PCR) negative, 30% were SARS-CoV-2 serology positive, and 60% had elevated D-dimers. Histology obtained from 19 of the patients revealed lymphocytic inflammation and vascular damage, and 8 had IgA positivity.
In a retrospective analysis of seven pediatric chilblains cases during the pandemic, researchers examined the skin biopsies to evaluate histopathological features and explored the presence of SARS-CoV-2 in the tissue. All patients were PCR negative. The authors observed cytoplasmic granular positivity for SARS-CoV-2 spike protein in endothelial cells, a feature that they said showed coronavirus-like particles, consistent with SARS-CoV-2.
Not all studies in the medical literature have demonstrated an association between pernio-like/chilblains-like lesions and COVID-19, though. An analysis of 23 patients, with skin eruptions considered associated with SARS-CoV-2 infections (including 21 cases of chilblains) during the first wave of the pandemic found that the antibody and T-cell response in patients with pandemic chilblains was the same as in negative controls.
“What’s remarkably interesting about this study is that they did autopsies of samples from patients who had died prepandemic, so there was no such thing as COVID-19,” said Dr. Fox, who was not involved with the study. “They stained for viral particles in those patients, and they were positive in a subset of patients. This makes me wonder about what the significance of that staining positivity is.”
Yet another group of investigators looked at what was happening with pernio during the waves of COVID in a study of chilblains cases in children in Spain, and found a stronger association between lockdown and cold temperature, which argues against a direct association between pernio and COVID infection.
In Dr. Fox’s experience, COVID toes can recur, especially upon exposure to cold. “What taught me this in real life is a patient who I saw remotely by video,” she recalled. “It was early on in the pandemic. I could not prove he had COVID no matter how hard I tried, but I do think he had COVID toes at that time.” When he later was confirmed to have COVID, “he got pernio in the same exact location as his original suspected COVID toes.”
According to an analysis of long COVID in the skin, based on cases reported to the American Academy of Dermatology–International League of Dermatological Societies registry from April 8 to Oct. 8, 2020, pernio-like lesions lasted a median of 12 days in patients with lab-confirmed COVID-19 and a median of 15 days in those with suspected COVID-19. But almost 7% of the 103 pernio cases were long-haulers, defined as those with dermatologic signs of COVID that lasted beyond 60 days.
“There are some patients who are resistant to treatment,” Dr. Fox said. “In addition, recurrent lesions make me think that maybe all pernio is triggered by some viral cause. This causes an immunologic phenomenon that’s responding to a viral trigger you’re trying to deal with. That may be the better way to think about COVID toes.”
Different variants of COVID also appear to be changing the characteristics of dermatologic manifestations associated with infection. Results from a large retrospective analysis of nearly 350,000 users of a COVID study App in the United Kingdom found that skin lesions were more predictive of a positive test in the Delta wave, compared with the Omicron wave, while pernio-like lesions were predictive of infection in the Delta wave but not in the Omicron wave.

Hidradenitis suppurativa
THE COMPARISON
Severe longstanding hidradenitis suppurativa (Hurley stage III) with architectural changes, ropy scarring, granulation tissue, and purulent discharge in the axilla of
A A 35-year-old Black man.
B A 42-year-old Hispanic woman with a light skin tone.
Hidradenitis suppurativa (HS) is a chronic inflammatory condition of the follicular epithelium that most commonly is found in the axillae and buttocks, as well as the inguinal, perianal, and submammary areas. It is characterized by firm and tender chronic nodules, abscesses complicated by sinus tracts, fistulae, and scarring thought to be related to follicular occlusion. Double-open comedones also may be seen.
The Hurley staging system is widely used to characterize the extent of disease in patients with HS:
- Stage I (mild): nodule(s) and abscess(es) without sinus tracts (tunnels) or scarring;
- Stage II (moderate): recurrent nodule(s) and abscess(es) with a limited number of sinus tracts and/or scarring; and
- Stage III (severe): multiple or extensive sinus tracts, abscesses, and/or scarring across the entire area.
Epidemiology
HS is most common in adults and African American patients. It has a prevalence of 1.3% in African Americans.1 When it occurs in children, it generally develops after the onset of puberty. The incidence is higher in females as well as individuals with a history of smoking and obesity (a higher body mass index).2-5
Key clinical features in people with darker skin tones
The erythema associated with HS may be difficult to see in darker skin tones, but violaceous, dark brown, and gray lesions may be present. When active HS lesions subside, intense hyperpigmentation may be left behind, and in some skin tones a pink or violaceous lesion may be apparent.
Worth noting
HS is disfiguring and has a negative impact on quality of life, including social relationships. Mental health support and screening tools are useful. Pain also is a common concern and may warrant referral to a pain specialist.6 In early disease, HS lesions can be misdiagnosed as an infection that recurs in the same location.
Treatments for HS include oral antibiotics (ie, tetracyclines, rifampin, clindamycin), topical antibiotics, immunosuppressing biologics, metformin, and spironolactone.7 Surgical interventions may be considered earlier in HS management and vary based on the location and severity of the lesions.8
Patients with HS are at risk for developing squamous cell carcinoma in scars, even many years later9; therefore, patients should perform skin checks and be referred to a dermatologist. Squamous cell carcinoma is most commonly found on the buttocks of men with HS and has a poor prognosis.
Health disparity highlight
Although those of African American and African descent have the highest rates of HS,1 the clinical trials for adalimumab (the only biologic approved for HS) enrolled a low number of Black patients.
Thirty HS comorbidities have been identified. Garg et al10 recommended that dermatologists perform examinations for comorbid conditions involving the skin and conduct a simple review of systems for extracutaneous comorbidities. Access to medical care is essential, and health care system barriers affect the ability of some patients to receive adequate continuity of care.
The diagnosis of HS often is delayed due to a lack of knowledge about the condition in the medical community at large and delayed presentation to a dermatologist.

Sustained response at 2 years reported for newly approved oral psoriasis agent
MILAN – The day after deucravacitinib became the first TYK2 inhibitor approved for the treatment of moderate to severe psoriasis, long-term data were presented at the annual congress of the European Academy of Dermatology and Venereology, suggesting that a high degree of benefit persists for at least 2 years, making this oral drug a potential competitor for biologics.
,” said Mark G. Lebwohl, MD, professor of dermatology and dean of clinical therapeutics, Icahn School of Medicine at Mount Sinai, New York.
Just 2 months after the 52-week data from the phase 3 POETYK PSO-1 trial were published online in the Journal of the American Academy of Dermatology, a long-term extension study found essentially no loss of benefit at 112 weeks, according to Dr. Lebwohl.
One of the two co-primary endpoints was a 75% clearance on the Psoriasis and Severity Index (PASI75) score. At 52 weeks, 80.2% of patients on deucravacitinib had met this criterion of benefit. At 112 weeks, the proportion was 84.4%.
The other primary endpoint was a static Physician’s Global Assessment (sPGA) score of clear or almost clear skin. The proportion of patients meeting this criterion at weeks 52 and 112 weeks were 65.6% and 67.6%, respectively.
When assessed by Treatment Failure Rule (TFR) or modified nonresponder imputation (mNRI), results were similar. For both, the primary endpoints at every time interval were just one or two percentage points lower but not clinically meaningfully different, according to Dr. Lebwohl.
The same type of sustained response out to 112 weeks was observed in multiple analyses. When the researchers isolated the subgroup of patients who had achieved a PASI 75 response at 16 weeks (100%), there was a modest decline in the PASI 75 rate at week 52 (90.2%) but then no additional decline at week 112 (91.3%).
There were essentially no changes in the PASI 90 rates at week 16 (63%), week 52 (65.3%), and week 112 (63.1%), Dr. Lebwohl reported. PASI 100 rates, once achieved, were sustained long term.
The target, TYK2, is one of four Janus kinase (JAK) inhibitors. Until now, almost all JAK inhibitors have had greater relative specificity for JAK 1, JAK 2, and JAK 3, but several inhibitors of TYK2 inhibitors other than deucravacitinib are in development for inflammatory diseases. Deucravacitinib (Sotyktu), approved by the Food and Drug Administration on Sept. 9, is the only TYK2 inhibitor with regulatory approval for plaque psoriasis.
In the POETYK PSO-1 trial, 666 patients were initially randomized in a 2:1:1 ratio to 6 mg deucravacitinib (now the approved dose), placebo, or the oral phosphodiesterase 4 inhibitor apremilast. At week 16, patients on placebo were switched over to deucravacitinib. At week 24, patients who did not achieve a PASI 50 on apremilast (which had been titrated to 10 mg daily to 30 mg twice a day over the first 5 days of dosing) were switched to deucravacitinib.
In the previously reported data, deucravacitinib was superior for all efficacy endpoints at week 16, including an analysis of quality of life when compared with placebo (P < .0001) or apremilast (P = .0088). At week 52, after having been switched to deucravacitinib at week 16, patients on placebo achieved comparable responses on the efficacy measures in this study, including PASI75.
Relative to JAK inhibitors commonly used in rheumatoid arthritis and other inflammatory diseases, the greater specificity of deucravacitinib for TYK2 appears to have meaningful safety advantages, according to Dr. Lebwohl. Targeted mostly on the TYK2 regulatory domain, deucravacitinib largely avoids inhibition of the JAK 1, 2, and 3 subtypes. Dr. Lebwohl said this explains why deucravacitinib labeling does not share the boxed warnings about off-target effects, such as those on the cardiovascular system, that can be found in the labeling of other JAK inhibitors.
In the published 52-week data, the discontinuation rate for adverse events was lower in the group randomized to deucravacitinib arm than in the placebo arm. In the extended follow-up, there were no new signals for adverse events, including those involving the CV system or immune function.
The key message so far from the long-term follow-up, which is ongoing, is that “continuous treatment with deucravacitinib is associated with durable efficacy,” Dr. Lebwohl said. It is this combination of sustained efficacy and safety that led Dr. Lebwohl to suggest it as a reasonable oral competitor to injectable biologics.
“Patients now have a choice,” he said.
Jashin J. Wu, MD, a board member of the National Psoriasis Foundation and an associate professor in the department of dermatology, University of Miami, has been following the development of deucravacitinib. He said that the recent FDA approval validates the clinical evidence of benefit and safety, while the long-term data presented at the EADV congress support its role in expanding treatment options.
“Deucravacitinib is a very effective oral agent for moderate to severe plaque psoriasis with strong maintenance of effect through week 112,” he said. Differentiating it from other JAK inhibitors, the FDA approval “confirms the safety of this agent as there is no boxed warning,” he added.
Dr. Lebwohl reports financial relationships with more than 30 pharmaceutical companies, including Bristol-Myers Squibb, the manufacturer of deucravacitinib. Dr. Wu has financial relationships with 14 pharmaceutical companies, including Bristol-Myers Squibb, but he was not an investigator for the phase 3 trials of deucravacitinib.
MILAN – The day after deucravacitinib became the first TYK2 inhibitor approved for the treatment of moderate to severe psoriasis, long-term data were presented at the annual congress of the European Academy of Dermatology and Venereology, suggesting that a high degree of benefit persists for at least 2 years, making this oral drug a potential competitor for biologics.
,” said Mark G. Lebwohl, MD, professor of dermatology and dean of clinical therapeutics, Icahn School of Medicine at Mount Sinai, New York.
Just 2 months after the 52-week data from the phase 3 POETYK PSO-1 trial were published online in the Journal of the American Academy of Dermatology, a long-term extension study found essentially no loss of benefit at 112 weeks, according to Dr. Lebwohl.
One of the two co-primary endpoints was a 75% clearance on the Psoriasis and Severity Index (PASI75) score. At 52 weeks, 80.2% of patients on deucravacitinib had met this criterion of benefit. At 112 weeks, the proportion was 84.4%.
The other primary endpoint was a static Physician’s Global Assessment (sPGA) score of clear or almost clear skin. The proportion of patients meeting this criterion at weeks 52 and 112 weeks were 65.6% and 67.6%, respectively.
When assessed by Treatment Failure Rule (TFR) or modified nonresponder imputation (mNRI), results were similar. For both, the primary endpoints at every time interval were just one or two percentage points lower but not clinically meaningfully different, according to Dr. Lebwohl.
The same type of sustained response out to 112 weeks was observed in multiple analyses. When the researchers isolated the subgroup of patients who had achieved a PASI 75 response at 16 weeks (100%), there was a modest decline in the PASI 75 rate at week 52 (90.2%) but then no additional decline at week 112 (91.3%).
There were essentially no changes in the PASI 90 rates at week 16 (63%), week 52 (65.3%), and week 112 (63.1%), Dr. Lebwohl reported. PASI 100 rates, once achieved, were sustained long term.
The target, TYK2, is one of four Janus kinase (JAK) inhibitors. Until now, almost all JAK inhibitors have had greater relative specificity for JAK 1, JAK 2, and JAK 3, but several inhibitors of TYK2 inhibitors other than deucravacitinib are in development for inflammatory diseases. Deucravacitinib (Sotyktu), approved by the Food and Drug Administration on Sept. 9, is the only TYK2 inhibitor with regulatory approval for plaque psoriasis.
In the POETYK PSO-1 trial, 666 patients were initially randomized in a 2:1:1 ratio to 6 mg deucravacitinib (now the approved dose), placebo, or the oral phosphodiesterase 4 inhibitor apremilast. At week 16, patients on placebo were switched over to deucravacitinib. At week 24, patients who did not achieve a PASI 50 on apremilast (which had been titrated to 10 mg daily to 30 mg twice a day over the first 5 days of dosing) were switched to deucravacitinib.
In the previously reported data, deucravacitinib was superior for all efficacy endpoints at week 16, including an analysis of quality of life when compared with placebo (P < .0001) or apremilast (P = .0088). At week 52, after having been switched to deucravacitinib at week 16, patients on placebo achieved comparable responses on the efficacy measures in this study, including PASI75.
Relative to JAK inhibitors commonly used in rheumatoid arthritis and other inflammatory diseases, the greater specificity of deucravacitinib for TYK2 appears to have meaningful safety advantages, according to Dr. Lebwohl. Targeted mostly on the TYK2 regulatory domain, deucravacitinib largely avoids inhibition of the JAK 1, 2, and 3 subtypes. Dr. Lebwohl said this explains why deucravacitinib labeling does not share the boxed warnings about off-target effects, such as those on the cardiovascular system, that can be found in the labeling of other JAK inhibitors.

Targeted anti-IgE therapy found safe and effective for chronic urticaria
MILAN – The therapeutic .
Both doses of ligelizumab evaluated met the primary endpoint of superiority to placebo for a complete response at 16 weeks of therapy, reported Marcus Maurer, MD, director of the Urticaria Center for Reference and Excellence at the Charité Hospital, Berlin.
The data from the two identically designed trials, PEARL 1 and PEARL 2, were presented at the annual congress of the European Academy of Dermatology and Venereology. The two ligelizumab experimental arms (72 mg or 120 mg administered subcutaneously every 4 weeks) and the active comparative arm of omalizumab (300 mg administered subcutaneously every 4 weeks) demonstrated similar efficacy, all three of which were highly superior to placebo.
The data show that “another anti-IgE therapy – ligelizumab – is effective in CSU,” Dr. Maurer said.
“While the benefit was not different from omalizumab, ligelizumab showed remarkable results in disease activity and by demonstrating just how many patients achieved what we want them to achieve, which is to have no more signs and symptoms,” he added.
Majority of participants with severe urticaria
All of the patients entered into the two trials had severe (about 65%) or moderate (about 35%) symptoms at baseline. The results of the two trials were almost identical. In the randomization arms, a weekly Urticaria Activity Score (UAS7) of 0, which was the primary endpoint, was achieved at week 16 by 31.0% of those receiving 72-mg ligelizumab, 38.3% of those receiving 120-mg ligelizumab, and 34.1% of those receiving omalizumab (Xolair). The placebo response was 5.7%.
The UAS7 score is drawn from two components, wheals and itch. The range is 0 (no symptoms) to 42 (most severe). At baseline, the average patients’ scores were about 30, which correlates with a substantial symptom burden, according to Dr. Maurer.
The mean reduction in the UAS7 score in PEARL 2, which differed from PEARL 1 by no more than 0.4 points for any treatment group, was 19.2 points in the 72-mg ligelizumab group, 19.3 points in the 120-mg ligelizumab group, 19.6 points in the omalizumab group, and 9.2 points in the placebo group. There were no significant differences between any active treatment arm.
Complete symptom relief, meaning a UAS7 score of 0, was selected as the primary endpoint, because Dr. Maurer said that this is the goal of treatment. Although he admitted that a UAS7 score of 0 is analogous to a PASI score in psoriasis of 100 (complete clearing), he said, “Chronic urticaria is a debilitating disease, and we want to eliminate the symptoms. Gone is gone.”
Combined, the two phase 3 trials represent “the biggest chronic urticaria program ever,” according to Dr. Maurer. The 1,034 patients enrolled in PEARL 1 and the 1,023 enrolled in PEARL 2 were randomized in a 3:3:3:1 ratio with placebo representing the smaller group.
The planned follow-up is 52 weeks, but the placebo group will be switched to 120 mg ligelizumab every 4 weeks at the end of 24 weeks. The switch is required because “you cannot maintain patients with this disease on placebo over a long period,” Dr. Maurer said.
Ligelizumab associated with low discontinuation rate
Adverse events overall and stratified by severity have been similar across treatment arms, including placebo. The possible exception was a lower rate of moderate events (16.5%) in the placebo arm relative to the 72-mg ligelizumab arm (19.8%), the 120-mg ligelizumab arm (21.6%), and the omalizumab arm (22.3%). Discontinuations because of an adverse event were under 4% in every treatment arm.
Although Dr. Maurer did not present outcomes at 52 weeks, he did note that “only 15% of those who enrolled in these trials have discontinued treatment.” He considered this remarkable in that the study was conducted in the midst of the COVID-19 pandemic, and it appears that at least some of those left the trial did so because of concern for clinic visits.
Despite the similar benefit provided by ligelizumab and omalizumab, Dr. Maurer said that subgroup analyses will be coming. The possibility that some patients benefit more from one than the another cannot yet be ruled out. There are also, as of yet, no data to determine whether at least some patients respond to one after an inadequate response to the other.
Still, given the efficacy and the safety of ligelizumab, Dr. Maurer indicated that the drug is likely to find a role in routine management of CSU if approved.
“We only have two options for chronic spontaneous urticaria. There are antihistamines, which do not usually work, and omalizumab,” he said. “It is very important we develop more treatment options.”
Adam Friedman, MD, professor and chair of dermatology, George Washington University, Washington, agreed.
“More therapeutic options, especially for disease states that have a small armament – even if equivalent in efficacy to established therapies – is always a win for patients as it almost always increases access to treatment,” Dr. Friedman said in an interview.
“Furthermore, the heterogeneous nature of inflammatory skin diseases is often not captured in even phase 3 studies. Therefore, having additional options could offer relief where previous therapies have failed,” he added.
Dr. Maurer reports financial relationships with more than 10 pharmaceutical companies, including Novartis, which is developing ligelizumab. Dr. Friedman has a financial relationship with more than 20 pharmaceutical companies but has no current financial association with Novartis and was not involved in the PEARL 1 and 2 trials.

FDA warns of cancer risk in scar tissue around breast implants
.
The FDA safety communication is based on several dozen reports of these cancers occurring in the capsule or scar tissue around breast implants. This issue differs from breast implant–associated anaplastic large-cell lymphoma (BIA-ALCL) – a known risk among implant recipients.
“After preliminary review of published literature as part of our ongoing monitoring of the safety of breast implants, the FDA is aware of less than 20 cases of SCC and less than 30 cases of various lymphomas in the capsule around the breast implant,” the agency’s alert explains.
One avenue through which the FDA has identified cases is via medical device reports. As of Sept. 1, the FDA has received 10 medical device reports about SCC related to breast implants and 12 about various lymphomas.
The incidence rate and risk factors for these events are currently unknown, but reports of SCC and various lymphomas in the capsule around the breast implants have been reported for both textured and smooth breast implants, as well as for both saline and silicone breast implants. In some cases, the cancers were diagnosed years after breast implant surgery.
Reported signs and symptoms included swelling, pain, lumps, or skin changes.
Although the risks of SCC and lymphomas in the tissue around breast implants appears rare, “when safety risks with medical devices are identified, we wanted to provide clear and understandable information to the public as quickly as possible,” Binita Ashar, MD, director of the Office of Surgical and Infection Control Devices, FDA Center for Devices and Radiological Health, explained in a press release.
Patients and providers are strongly encouraged to report breast implant–related problems and cases of SCC or lymphoma of the breast implant capsule to MedWatch, the FDA’s adverse event reporting program.
The FDA plans to complete “a thorough literature review” as well as “identify ways to collect more detailed information regarding patient cases.”

The FDA safety communication is based on several dozen reports of these cancers occurring in the capsule or scar tissue around breast implants. This issue differs from breast implant–associated anaplastic large-cell lymphoma (BIA-ALCL) – a known risk among implant recipients.
“After preliminary review of published literature as part of our ongoing monitoring of the safety of breast implants, the FDA is aware of less than 20 cases of SCC and less than 30 cases of various lymphomas in the capsule around the breast implant,” the agency’s alert explains.
One avenue through which the FDA has identified cases is via medical device reports. As of Sept. 1, the FDA has received 10 medical device reports about SCC related to breast implants and 12 about various lymphomas.
The incidence rate and risk factors for these events are currently unknown, but reports of SCC and various lymphomas in the capsule around the breast implants have been reported for both textured and smooth breast implants, as well as for both saline and silicone breast implants. In some cases, the cancers were diagnosed years after breast implant surgery.
Reported signs and symptoms included swelling, pain, lumps, or skin changes.
Although the risks of SCC and lymphomas in the tissue around breast implants appears rare, “when safety risks with medical devices are identified, we wanted to provide clear and understandable information to the public as quickly as possible,” Binita Ashar, MD, director of the Office of Surgical and Infection Control Devices, FDA Center for Devices and Radiological Health, explained in a press release.

An asymptomatic rash
This patient was given a diagnosis of confluent and reticulated papillomatosis (CRP) based on the clinical presentation.
CRP is characterized by centrally confluent and peripherally reticulated scaly brown plaques and papules that are cosmetically disfiguring.1 CRP is usually asymptomatic and primarily impacts young adults—especially teenagers.2,3 It affects both males and females and commonly occurs on the trunk.1-3 CRP is believed to be a disorder of keratinization. Malassezia furfur may induce CRP’s hyperproliferative epidermal changes, but systemic treatment that eliminates this organism does not clear CRP.3
A CRP diagnosis is made based on clinical presentation. The eruption usually begins as verrucous papules in the inframammary or epigastric region that enlarge to 4 to 5 mm in diameter and coalesce to form a confluent plaque with a peripheral reticulated pattern. CRP can extend over the back, chest, and abdomen to the neck, shoulders, and gluteal cleft. CRP does not affect the oral mucosa, and rarely involves flexural areas, which differentiates it from the similar looking acanthosis nigricans.2 Although most cases are asymptomatic, mild pruritus may occur.1,2
A skin biopsy is rarely necessary for making a CRP diagnosis, but histopathologic findings include papillomatosis, hyperkeratosis, variable acanthosis, follicular plugging, and sparse dermal inflammation.1,3
Systemic antibiotics, most commonly minocycline 100 mg bid for 30 days or doxycycline 100 mg bid for 30 days, are safe and effective for CRP.1,4 Sometimes treatment is extended for as long as 6 months. Although CRP usually responds to minocycline or doxycycline, it is believed that this is the result of these drugs’ anti-inflammatory—rather than antibiotic—properties.1,2,4 Azithromycin is an effective alternative therapy.2,4 There is a high rate of recurrence of CRP in patients after systemic antibiotics are discontinued.2 Uniform responses to treatment and retreatment of flares have solidified the belief that antibiotics are an effective suppressive (if not curative) therapy despite a lack of randomized controlled trials.4
This patient was treated with minocycline 100 mg bid. After 1 month, the rash had improved by 70%. At 3 months, it was completely clear, and treatment was discontinued.

Roflumilast foam effectively eases seborrheic dermatitis
.
More than half experienced clearance of their symptoms, and three out of five achieved a significant improvement in pruritus, it was revealed during a late-breaking session at the annual congress of the European Academy of Dermatology and Venereology.
Common condition led to rapid recruitment
“Seborrheic dermatitis is a disease that’s very common, yet in my opinion, undertreated in dermatology,” said Andrew Blauvelt, MD, MBA, who presented the findings.
“It’s so common that when we did this trial, I was very surprised to see how easy it was to recruit,” said Dr. Blauvelt, a dermatologist who is president of the Oregon Medical Research Center, Portland. “Patients came in rapidly, out of the woodwork – they were desperate.”
While there are several tried and tested treatments for the condition, such as topical steroids and antifungal agents, he noted that they have their limitations: “Sometimes efficacy, sometimes the ability to be used on hair-bearing areas.”
Roflumilast is a phosphodiesterase 4 (PDE4) inhibitor that is available for topical use in a 0.3% cream formulation (Zoryve). This formulation gained FDA approval for plaque psoriasis for patients ages 12 and older this summer and is also under investigation as a treatment for atopic dermatitis.
It’s the same product in both preparations, Dr. Blauvelt said during the discussion period. “The only major difference between the cream and the foam is the propellant used to make it into a foam. Otherwise, they have the exact same list of ingredients.”
Dr. Blauvelt reported that just over 450 patients had been recruited at 53 U.S. centers into the 8-week, double-blind, placebo-controlled trial.
For inclusion, patients had to have moderate seborrheic dermatitis, defined as an Investigator’s Global Assessment (IGA) score of three or more. Dr. Blauvelt noted that patients as young as 9 years old could be recruited, and there was no upper age limit. The average age of participating patients, however, was around 42 years.
Multiple improvements seen in ‘happy trial’
The primary endpoint was an IGA score of 0 or 1 with at least a 2-grade improvement (IGA success) after 8 weeks of treatment. This was achieved by 80% of patients who were treated with roflumilast 0.3% foam, compared with 60% of those who were treated with the vehicle (P less than .0001).
Dr. Blauvelt pointed out that significant improvements had also been seen after 2 weeks (about 42% vs. about 26%; P = .0003) and 4 weeks (about 72% vs. about 49%; P less than .0001) of treatment.
“Now if we raise the bar a little higher” and ask how many patients were completely clear of their seborrheic dermatitis, Dr. Blauvelt said, it was 50% at 8 weeks, more than a third at 4 weeks, over 15% at 2 weeks with the foam, and significantly lower at just under 30%, 15%, and 7% in the vehicle group.
A 4-point or more improvement in the Worst Itch Numeric Rating Scale (WI-NRS) – accepted as the minimally clinically important difference – was achieved by more than 60% of patients treated with the foam at week 8, just under 50% at week 4, and just over 30% at week 2. Corresponding rates in the vehicle group were around 40%, 30%, and 15%.
“Many patients responded in this trial. So much so that when I was doing it, I called it the ‘happy trial.’ Every time I saw patients in this trial, they seemed to be happy,” Dr. Blauvelt said anecdotally.
“In terms of adverse events, the drug turned out to be very safe, and there didn’t seem to be any issues with any things that we see with, for example, oral phosphodiesterase inhibitors,” he added.
The tolerability findings suggest that the foam vehicle “was an excellent vehicle to be used for this particular drug,” with no signs of skin irritation, as rated by patients or investigators.
Lesson for practice: Advise patients to moisturize?
“It seems like the vehicle would be a good skincare product for patients,” observed the session’s cochair, Jo Lambert, MD, PhD, professor and academic head of the department of dermatology at Ghent University Hospital, Belgium.
It was “a pretty dramatic vehicle response, right?” Dr. Blauvelt responded. “We normally don’t think of telling seborrheic dermatitis patients to moisturize,” he added.
“I think one of the interesting findings is perhaps we should be telling them to moisturize their scalp or moisturize their face, or it could be something unique to this particular foam.”
The study was funded by Arcutis Biotherapeutics. Dr. Blauvelt disclosed that he was an investigator for the trial and acted as consultant to the company, receiving grants/research funding and/or honoraria. Several of the study’s co-investigators are employees of Arcutis. Dr. Lambert was not involved in the study and cochaired the late-breaking session during which the STRATUM trial findings were reported.

FROM THE EADV CONGRESS
Dupilumab offers ‘clinically meaningful’ improvements in prurigo nodularis
(Dupixent), indicate results from the phase 2 LIBERTY-PN PRIME trial.
The research was presented at the annual Congress of the European Academy of Dermatology and Venereology.
More than 150 patients with severe PN whose quality of life was impaired were randomly assigned to receive dupilumab (Dupixent) or placebo for 24 weeks. Use of the monoclonal antibody was associated with significant improvements in itch scores.
The researchers also found that the percentage of patients who had no or few PN lesions increased substantially with use of dupilumab, and there were no new safety signals, confirming results from previous studies. Dupilumab, an interleukin-4 receptor alpha antagonist administered by injection, was initially approved by the U.S. Food and Drug Administration for treating atopic dermatitis in 2022.
Study presenter Gil Yosipovitch, MD, professor of dermatology at the University of Miami, emphasized that the improvements in itch and skin lesions seen in these patients were “clinically meaningful.”
In the discussion after the presentation, Dr. Yosipovitch was asked whether the presence or absence of atopy had any bearing on the results.
He replied that although there were too few patients with atopy in the current study to answer that question, other data indicate that there is no overall difference between patients with atopy and those without atopy.
Asked whether dupilumab should be used for only 24 weeks, Dr. Yosipovitch said his that “impression” is that there can be a “honeymoon period” during which the medication is stopped and the treating clinician sees “what happens.”
“It would be interesting in the future” to find out, he added, but he noted that whatever the result, patients would need treatment “for the rest of their life.”
Dr. Yosipovitch, director of the Miami Itch Center and the study’s principal investigator, began his presentation by noting that currently, no systemic therapies have been approved by the FDA or the European Medicines Agency for PN.
Although treatments such as topical medications, ultraviolet light therapy, immunosuppressive agents, and systemic neuromodulators are used off label, for many patients with moderate to severe PN, disease control is inadequate, and the patients are “miserable.”
Recently, the phase 3 LIBERTY-PN PRIME2 trial showed that dupilumab significantly reduced itch and skin lesions for patients with PN, and the safety profile was consistent with that seen in approved indications for the drug.
Dr. Yosipovitch explained that LIBERTY-PN PRIME was a phase 2 study in which, after a screening period, patients with PN were randomly assigned in a 1:1 ratio to receive dupilumab as a 600-mg loading dose followed by 300 mg twice weekly or a matched placebo. Treatment was given for 24 weeks, after which there was a post treatment 12-week follow-up period.
Participants were aged 18-80 years and had been diagnosed with PN for a period of at least 3 months. To be included in the trial, patients had to have an average Worst Itch Numerical Rating Scale (WI-NRS) score of at least 7 and at least 20 lesions, among other criteria. (Patients were allowed to continue treatment with mid- to low-potency topical steroids or topical calcineurin inhibitors if they had been taking them at baseline.)
Among 151 patients in the study, the mean age was 50.1 years, and 66.2% were women. The majority (53.0%) were White; 7.3% were Black; and 35.8% were Asian; 40.4% of patients had a history of atopy. The mean WI-NRS was 8.5, and the mean skin pain score on a 10-point scale was 7.2.
The Investigator’s Global Assessment for PN stage of disease (IGA PN-S) was also employed in the trial. That measure uses a 5-point scale to assess disease severity, with 0 indicating no lesions and 4 indicating more than 100 lesions. At baseline, 28.7% of patients had a score of 4, and the remainder had a score of 3, indicating the presence of 20-100 PN lesions.
Dr. Yosipovitch said that quality of life for these patients was “low” and that scores on the Hospital Anxiety and Depression scale indicated that the participants, many of whom had previously received topical and systemic medications for their PN, indicated they were depressed.
He showed that at week 24, the proportion of patients who had experienced an improvement in the WI-NRS score of greater than or equal to 4 (the study’s primary endpoint) was significantly greater with dupilumab, at 60.0% versus 18.4% among patients given placebo (P < .0001).
Moreover, the proportion of patients at week 24 with an IGA PN-S score of 0 or 1 (the secondary endpoint) was 48.0% in the active treatment group, versus 18.4% with placebo (P =.0004).
With regard to safety, rates of any treatment-emergent adverse events were similar between the groups, at 70.7% for dupilumab and 62.7% for placebo, as were rates for severe treatment-emergent adverse events, at 6.7% and 10.7%, respectively.
Rates of treatment-emergent adverse events of interest, such as skin infections, conjunctivitis, herpes viral infections, and injection site reactions, also suggested that there was no increased risk with active treatment.
Dupilumab is currently under review at the FDA and in Europe for the treatment of PN, according to dupilumab manufacturers Regeneron and Sanofi.
The study was sponsored by Sanofi in collaboration with Regeneron Pharmaceuticals. Dr. Yosipovitch has relationships with Arcutis Biotherapeutics, Bellus Health, Eli Lilly, Galderma, GSK, Kiniksa Pharmaceuticals, LEO Pharma, Novartis, Pfizer, Regeneron Pharmaceuticals, Sanofi, and Trevi Therapeutics.

(Dupixent), indicate results from the phase 2 LIBERTY-PN PRIME trial.
The research was presented at the annual Congress of the European Academy of Dermatology and Venereology.
More than 150 patients with severe PN whose quality of life was impaired were randomly assigned to receive dupilumab (Dupixent) or placebo for 24 weeks. Use of the monoclonal antibody was associated with significant improvements in itch scores.
The researchers also found that the percentage of patients who had no or few PN lesions increased substantially with use of dupilumab, and there were no new safety signals, confirming results from previous studies. Dupilumab, an interleukin-4 receptor alpha antagonist administered by injection, was initially approved by the U.S. Food and Drug Administration for treating atopic dermatitis in 2022.
Study presenter Gil Yosipovitch, MD, professor of dermatology at the University of Miami, emphasized that the improvements in itch and skin lesions seen in these patients were “clinically meaningful.”
In the discussion after the presentation, Dr. Yosipovitch was asked whether the presence or absence of atopy had any bearing on the results.
He replied that although there were too few patients with atopy in the current study to answer that question, other data indicate that there is no overall difference between patients with atopy and those without atopy.
Asked whether dupilumab should be used for only 24 weeks, Dr. Yosipovitch said his that “impression” is that there can be a “honeymoon period” during which the medication is stopped and the treating clinician sees “what happens.”
“It would be interesting in the future” to find out, he added, but he noted that whatever the result, patients would need treatment “for the rest of their life.”
Dr. Yosipovitch, director of the Miami Itch Center and the study’s principal investigator, began his presentation by noting that currently, no systemic therapies have been approved by the FDA or the European Medicines Agency for PN.
Although treatments such as topical medications, ultraviolet light therapy, immunosuppressive agents, and systemic neuromodulators are used off label, for many patients with moderate to severe PN, disease control is inadequate, and the patients are “miserable.”
Recently, the phase 3 LIBERTY-PN PRIME2 trial showed that dupilumab significantly reduced itch and skin lesions for patients with PN, and the safety profile was consistent with that seen in approved indications for the drug.
Dr. Yosipovitch explained that LIBERTY-PN PRIME was a phase 2 study in which, after a screening period, patients with PN were randomly assigned in a 1:1 ratio to receive dupilumab as a 600-mg loading dose followed by 300 mg twice weekly or a matched placebo. Treatment was given for 24 weeks, after which there was a post treatment 12-week follow-up period.
Participants were aged 18-80 years and had been diagnosed with PN for a period of at least 3 months. To be included in the trial, patients had to have an average Worst Itch Numerical Rating Scale (WI-NRS) score of at least 7 and at least 20 lesions, among other criteria. (Patients were allowed to continue treatment with mid- to low-potency topical steroids or topical calcineurin inhibitors if they had been taking them at baseline.)
Among 151 patients in the study, the mean age was 50.1 years, and 66.2% were women. The majority (53.0%) were White; 7.3% were Black; and 35.8% were Asian; 40.4% of patients had a history of atopy. The mean WI-NRS was 8.5, and the mean skin pain score on a 10-point scale was 7.2.
The Investigator’s Global Assessment for PN stage of disease (IGA PN-S) was also employed in the trial. That measure uses a 5-point scale to assess disease severity, with 0 indicating no lesions and 4 indicating more than 100 lesions. At baseline, 28.7% of patients had a score of 4, and the remainder had a score of 3, indicating the presence of 20-100 PN lesions.

FROM THE EADV CONGRESS
Dermatoses often occur in people who wear face masks
according to a recently published systematic review and meta-analysis.
“This report finds the most statistically significant risk factor for developing a facial dermatosis under a face mask is how long one wears the mask. Specifically, wearing a mask for more than 4 to 6 hours correlated most strongly with the development of a facial skin problem,” Jami L. Miller, MD, associate professor of dermatology, Vanderbilt University Medical Center, Nashville, Tenn., told this news organization. Dr. Miller was not involved in the study.
“The type of mask and the environment were of less significance,” she added.
Mask wearing for infection control has been common during the COVID-19 pandemic and will likely continue for some time, study coauthors Lim Yi Shen Justin, MBBS, and Yik Weng Yew*, MBBS, MPH, PhD, Lee Kong Chian School of Medicine, Nanyang Technological University, Singapore, write in Contact Dermatitis. And cross-sectional studies have suggested a link between mask wearing and various facial dermatoses.
To evaluate this link, as well as potential risk factors for facial dermatoses, the researchers reviewed 37 studies published between 2004 and 2022 involving 29,557 adult participants self-reporting regular use of any face mask type across 17 countries in Europe and Asia. The mask types commonly studied in the papers they analyzed included surgical masks and respirators.
Facial dermatoses were self-reported in 30 studies (81.1%) and were diagnosed by trained dermatologists in seven studies (18.9%).
Dr. Justin and Dr. Yew found that:
- The overall prevalence of facial dermatoses was 55%
- Individually, facial dermatitis, itch, acne, and pressure injuries were consistently reported as facial dermatoses, with pooled prevalence rates of 24%, 30%, 31%, and 31%, respectively
- The duration of mask wearing was the most significant risk factor for facial dermatoses (P < .001)
- Respirators, including N95 masks, were not more likely than surgical masks to be linked with facial dermatoses
“Understanding risk factors of mask wearing, including situation, duration, and type of mask, may allow for targeted interventions to mitigate problems,” Dr. Yew told this news organization.
He advised taking a break from mask wearing after 4 to 6 hours to improve outcomes.
Dr. Yew acknowledged limitations, including that most of the reviewed studies relied on self-reported symptoms.
“Patient factors were not investigated in most studies; therefore, we were not able to ascertain their contributory role in the development of facial dermatoses from mask wearing,” he said. “We were also unable to prove causation between risk factors and outcome.”
Four dermatologists welcome the findings
Dr. Miller called this an “interesting, and certainly relevant” study, now that mask wearing is common and facial skin problems are fairly common complaints in medical visits.
“As the authors say, irritants or contact allergens with longer exposures can be expected to cause a more severe dermatitis than short contact,” she said. “Longer duration also can cause occlusion of pores and hair follicles, which can be expected to worsen acne and folliculitis.”
“I was surprised that the type of mask did not seem to matter significantly,” she added. “Patients wearing N95 masks may be relieved to know N95s do not cause more skin problems than lighter masks.”
Still, Dr. Miller had several questions, including if the materials and chemical finishes that vary by manufacturer may affect skin conditions.
Olga Bunimovich, MD, assistant professor, department of dermatology, University of Pittsburgh School of Medicine, Pennsylvania, called this study “an excellent step towards characterizing the role masks play in facial dermatoses.”
“The study provides a window into the prevalence of these conditions, as well as some understanding of the factors that may be contributing to it,” Dr. Bunimovich, who was not part of the study, added. But “we can also utilize this information to alter behavior in the work environment, allowing ‘mask-free’ breaks to decrease the risk of facial dermatoses.”
Elma Baron, MD, professor and director, Skin Study Center, department of dermatology, Case Western Reserve University School of Medicine, Cleveland, expected skin problems to be linked with mask wearing but didn’t expect the prevalence to be as high as 55%, which she called “very significant.”
“Mask wearing is an important means to prevent transmission of communicable infections, and the practice will most likely continue,” she said.
“Given the data, it is reasonable to advise patients who are already prone to these specific dermatoses to be proactive,” she added. “Early intervention with proper topical medications, preferably prescribed by a dermatologist or other health care provider, and changing masks frequently before they get soaked with moisture, will hopefully lessen the severity of skin rashes and minimize the negative impact on quality of life.”
Also commenting on the study, Susan Massick, MD, dermatologist and clinical associate professor of internal medicine, The Ohio State University Wexner Medical Center, Westerville, said in an interview that she urges people to wear masks, despite these risks.
“The majority of concerns are straightforward, manageable, and overall benign,” she said. “We have a multitude of treatments that can help control, address, or improve symptoms.”
“Masks are an effective and easy way to protect yourself from infection, and they remain one of the most reliable preventions we have,” Dr. Massick noted. “The findings in this article should not preclude anyone from wearing a mask, nor should facial dermatoses be a cause for people to stop wearing their masks.”
The study received no funding. The authors, as well as Dr. Baron, Dr. Miller, Dr. Bunimovich, and Dr. Massick, who were not involved in the study, reported no relevant financial relationships. All experts commented by email.
