WASHINGTON – Multiple biologic failure in a minority of patients with psoriasis may have several causes, from genetic endotypes and immunologic factors to lower serum drug levels, the presence of anti-drug antibody levels, female sex, and certain comorbidities, Wilson Liao, MD, said at the annual research symposium of the National Psoriasis Foundation.

“Tough-to-treat psoriasis remains a challenge despite newer therapies ... Why do we still have this sub-population of patients who seem to be refractory?” said Dr. Liao, professor and associate vice chair of research in the department of dermatology at the University of California, San Francisco, who coauthored a 2015-2022 prospective cohort analysis that documented about 6% of patients failing two or more biologic agents of different mechanistic classes.

“These patients are really suffering,” he said. “We need to have better guidelines and treatment algorithms for these patients.”

A significant number of patients with psoriatic arthritis (PsA), meanwhile, are inadequate responders to tumor necrosis factor (TNF) inhibition, Christopher T. Ritchlin, MD, PhD, professor of medicine in the division of allergy/immunology and rheumatology and the Center of Musculoskeletal Research at the University of Rochester (N.Y.), said during another session at the meeting.

The long-term “persistence,” or usage, of first-line biologics in patients with PsA – and of second-line biologics in patients who failed one TNF-inhibitor – is low, but the literature offers little information on the reasons for TNF-inhibitor discontinuation, said Dr. Ritchlin, who coauthored a perspective piece in Arthritis & Rheumatology on managing the patient with PsA who fails one TNF inhibitor.

Dr. Ritchlin and his coauthors were asked to provide evidence-informed advice and algorithms, but the task was difficult. “It’s hard to know what to recommend for the next step if we don’t know why patients failed the first,” he said. “The point is, we need more data. [Clinical trials] are not recording the kind of information we need.”
 

Anti-drug antibodies, genetics, other factors in psoriasis

Research shows that in large cohorts, “all the biologics do seem to lose efficacy over time,” said Dr. Liao, who directs the UCSF Psoriasis and Skin Treatment Center. “Some are better than others, but we do see a loss of effectiveness over time.”

A cohort study published in 2022 in JAMA Dermatology, for instance, documented declining “drug survival” associated with ineffectiveness during 2 years of treatment for each of five biologics studied (adalimumab [Humira], ustekinumab [Stelara], secukinumab [Cosentyx], guselkumab [Tremfya], and ixekizumab [Taltz]).

“There have been a number of theories put forward” as to why that’s the case, including lower serum drug levels, “which of course can be related to anti-drug antibody production,” he said.

He pointed to two studies of ustekinumab: One prospective observational cohort study that reported an association of lower early drug levels of the IL-12/23 receptor antagonist with lower Psoriasis Area and Severity Index (PASI) scores, and another observational study that documented an association between anti-drug antibody positivity with lower ustekinumab levels and impaired clinical response.

“We also now know ... that there are genetic endotypes in psoriasis, and that patients who are [HLA-C*06:02]-positive tend to respond a little better to drugs like ustekinumab, and those who are [HLA-C*06:02]-negative tend to do a little better with the TNF inhibitors,” Dr. Liao said. The human leukocyte antigen (HLA) allele HLA-C*06:02 is associated with susceptibility to psoriasis.

In a study using a national psoriasis registry, HLA-C*06:02-negative patients were 3 times more likely to achieve PASI90 status in response to adalimumab, a TNF-alpha inhibitor, than with ustekinumab treatment. And in a meta-analysis covering eight studies with more than 1,000 patients with psoriasis, the median PASI75 response rate after 6 months of ustekinumab therapy was 92% in the HLA-C*06:02-positive group and 67% in HLA-C*06:02-negative patients.

The recently published cohort study showing a 6% rate of multiple biologic failure evaluated patients in the multicenter CorEvitas Psoriasis Registry who initiated their first biologic between 2015 and 2020 and were followed for 2 or more years. Investigators looked for sociodemographic and clinical differences between the patients who continued use of their first biologic for at least 2 years (“good response”), and those who discontinued two or more biologics of different classes, each used for at least 90 days, because of inadequate efficacy.

Of 1,039 evaluated patients, 490 (47.2%) had good clinical response to their first biologic and 65 (6.3%) had multiple biologic failure. All biologic classes were represented among those who failed multiple biologics. The first and second biologic classes used were attempted for a mean duration of 10 months – “an adequate trial” of each, Dr. Liao said.

In multivariable regression analysis, six variables were significantly associated with multiple biologic failure: female sex at birth, shorter disease duration, earlier year of biologic initiation, prior nonbiologic systemic therapy, having Medicaid insurance, and a history of hyperlipidemia. The latter is “interesting because other studies have shown that metabolic syndrome, of which hyperlipidemia is a component, can also relate to poor response to biologics,” Dr. Liao said.

The most common sequences of first-to-second biologics among those with multiple biologic failure were TNF inhibitor to IL-17 inhibitor (30.8%); IL-12/23 inhibitor to IL-17 inhibitor (21.5%); TNF inhibitor to IL-12/23 inhibitor (12.3%); and IL-17 inhibitor to IL-23 inhibitor (10.8%).

The vast majority of patients failed more than two biologics, however, and “more than 20% had five or more biologics tried over a relatively short period,” Dr. Liao said.
 

Comorbidities and biologic failure in psoriasis, PsA

In practice, it was said during a discussion period, biologic failures in psoriasis can be of two types: a primary inadequate response or initial failure, or a secondary failure with initial improvement followed by declining or no response. “I agree 100% that these probably represent two different endotypes,” Dr. Liao said. “There’s research emerging that psoriasis isn’t necessarily a clean phenotype.”

The option of focusing on comorbidities in the face of biologic failure was another point of discussion. “Maybe the next biologic is not the answer,” a meeting participant said. “Maybe we should focus on metabolic syndrome.”

“I agree,” Dr. Liao said. “In clinic, there are people who may not respond to therapies but have other comorbidities and factors that make it difficult to manage [their psoriasis] ... that may be causative for psoriasis. Maybe if we treat the comorbidities, it will make it easier to treat the psoriasis.”

Addressing comorbidities and “extra-articular traits” such as poorly controlled diabetes, centralized pain, anxiety and depression, and obesity is something Dr. Ritchlin advocates for PsA. “Centralized pain, I believe, is a major driver of nonresponse,” he said at the meeting. “We have to be careful about blaming nonresponse and lack of efficacy of biologics when it could be a wholly different mechanism the biologic won’t treat ... for example, centralized pain.”

As with psoriasis, the emergence of antidrug antibodies may be one reason for the secondary failure of biologic agents for PsA, Dr. Ritchlin and his coauthors wrote in their paper on management of PsA after failure of one TNF inhibitor. Other areas to consider in evaluating failure, they wrote, are compliance and time of dosing, and financial barriers.

Low long-term persistence of second-line biologics for patients with PsA was demonstrated in a national cohort study utilizing the French health insurance database, Dr. Ritchlin noted at the research meeting. 

The French study covered almost 3,000 patients who started a second biologic after discontinuing a TNF inhibitor during 2015-2020. Overall, 1-year and 3-year persistence rates were 42% and 17%, respectively.

BERLIN – European guidelines now in press for the diagnosis and treatment of body dysmorphic disorder (BDD), a condition defined largely by abnormal perceptions about – and behavior surrounding personal appearance, were outlined in a late-breaker presentation at the annual Congress of the European Academy of Dermatology and Venereology.

The development of guidelines for BDD, a disorder familiar to many clinical dermatologists, is intended as a practical tool, according to Maria-Angeliki Gkini, MD, who has appointments at both Bart’s Health NHS Trust in London and the 401 General Army Hospital in Athens.

Consensus reached by 17 experts

Specifically, 17 experts, all of whom were members of the European Society for Dermatology and Psychiatry proceeded to systematically address a series of clinical questions and recommendations. Consensus was defined as at least 75% of the participants strongly agreeing or agreeing. Several rounds of discussion were often required.

Among the conclusions, the guidelines support uniform screening for BDD in all patients prior to cosmetic procedures. In identifying depression, anxiety, and distorted perceptions, simple tools, such as the Patient Health Questionnaire might be adequate for an initial evaluation, but Dr. Gkini also recommended routinely inquiring about suicidal ideation, which has been reported in up to 80% of individuals with BDD.

Other instruments for screening that can be considered include DSM-5 criteria for BDD and the Body Dysmorphic Disorder Questionnaire–Dermatology Version, which might be particularly useful and appropriate for dermatologists.

One of the reasons to screen for BDD is that these patients often convince themselves that some specific procedure is needed to resolve the source of their obsession. The goal of screening is to verify that it is the dermatologic concern, not an underlying psychiatric disorder that is driving their search for relief. The risk of dermatologic interventions is not only that expectations are not met, but the patient’s perception of a failed intervention “sometimes makes these worse,” Dr. Gkini explained.
 

Collaboration with psychiatrists recommended

The guidelines include suggestions for treatment of BDD. Of these, SSRIs are recommended at high relative doses, according to Dr. Gkini. Consistent with the consensus recommendation of collaborating with mental health specialists, she said that the recommendations acknowledge evidence of greater benefits when SSRIs are combined with psychotherapy.

Katharine A. Phillips, MD, professor of psychiatry at Weill Cornell Medicine, New York, has been conducting BDD research for several years and has written numerous books and articles about this topic, including a review in the journal Focus. She cautioned that, because of a normal concern for appearance, BDD is easily missed by dermatologists.

“For BDD to be diagnosed, the preoccupation with a nonexistent or slight defect in appearance must cause clinically significant distress or impairment in functioning,” she said in an interview. “This is necessary to differentiate BDD from more normal and common appearance concerns that do not qualify for the diagnosis”

She specified that patients should be considered for cognitive-behavioral therapy rather than psychotherapy, a generic term that covers many forms of treatment. She said that most other types of psychotherapy “are probably not effective” for BDD.

Dr. Phillips highly endorsed the development of BDD guidelines for dermatologists because of the frequency with which physicians in this specialty encounter BDD – and believes that more attention to this diagnosis is needed.

“I recommend that dermatologists who have a patient with BDD collaborate with a psychiatrist in delivering care with an SSRI,” she said. “High doses of these medications are often needed to effectively treat BDD.”

Dr. Gkini reported financial relationships with AbbVie, Almirall, Celgene, Eli Lilly, Janssen, LEO, Novartis, Sanofi, and Regenlab. Dr. Phillips reported no relevant financial relationships.

Dr. Gkini reported financial relationships with AbbVie, Almirall, Celgene, Eli Lilly, Janssen, LEO, Novartis, Sanofi, and Regenlab. Dr. Phillips reported no relevant financial relationships.

TOPLINE:

Most patients with psoriasis are not participating in highly shared decision-making (SDM) with clinicians about their care.

METHODOLOGY:

• Researchers drew from the 2014-2017 and 2019 Medical Expenditure Panel Survey (MEPS) to identify 3,715,027 patients with psoriasis, to evaluate the association between SDM (a patient-centered approach to selecting treatment on the basis of a discussion between the clinician and patient) and satisfaction with care.
• SDM was determined by patient responses on a 4-point Likert scale to seven MEPS variables, including the question, “How often did doctors or other health providers listen carefully to you?”
• Patient satisfaction with care was measured with a MEPS variable that asked respondents to rate their health care providers on a scale of 1-10.
• Researchers used multiple logistic regression to assess the association between SDM and demographic and clinical characteristics in patients with psoriasis, and multiple linear regression analysis to assess the association between SDM and patient satisfaction with care.

TAKEAWAY:

• The average SDM score was 3.6 out of 4, and the average satisfaction with care score was 8.6 out of 10.
• However, only about 42% of the cohort reported a high SDM, defined as a score of 3.9 or greater.
• After adjusting for covariates, the researchers found that patients who had high SDM had, on average, 85% higher satisfaction with care (P < .001).
• Compared with men, women had about 27% higher satisfaction with care (P = .023), whereas non-Hispanic patients had lower satisfaction with care compared with Hispanic patients (P = .037).

IN PRACTICE:

“It is important to construct a framework for carrying out SDM with patients with psoriasis to enhance clinician-patient communication and improve patient outcomes,” the authors concluded.

SOURCE:

April W. Armstrong, MD, MPH, chief of dermatology at the University of California, Los Angeles, led the research. The study was published online  in the Journal of the American Academy of Dermatology.

LIMITATIONS:

The ability to measure SDM in patients with psoriasis was limited by the seven items from MEPS. The diagnosis of psoriasis was based on self-report.

DISCLOSURES:

The study was funded by the National Psoriasis Foundation. Dr. Armstrong disclosed that she has served as a research investigator and/or scientific adviser to AbbVie, Almirall, Arcutis, ASLAN, Beiersdorf, Boehringer Ingelheim, Bristol Myers Squibb, EPI, Incyte, Leo, UCB, Janssen, Lilly, Nimbus, Novartis, Ortho Dermatologics, Sun, Dermavant, Dermira, Sanofi, Regeneron, Pfizer, and Modmed.

For some patients with atopic dermatitis (AD), dupilumab treatment can cause a benign reversible lymphoid reaction (LR) that mimics mycosis fungoides (MF) but differs histologically, according to a study published in JAMA Dermatology

The potential for such reactions requires diagnosing AD carefully, monitoring patients on dupilumab for new and unusual symptoms, and thoroughly working up suspicious LRs, according to an accompanying editorial and experts interviewed for this article.

“Dupilumab has become such an important first-line systemic medication for our patients with moderate to severe atopic dermatitis. It’s important for us to understand everything we can about its use in the real world – both good and bad,”Raj Chovatiya, MD, PhD, MSCI, assistant professor of dermatology at Northwestern University, Chicago, said in an interview. He was uninvolved with either publication.

Robert Sidbury, MD, MPH, added that, although the affected patient group was small, studying lymphoid reactions associated with dupilumab is important because of the risk for diagnostic misadventure that these reactions carry. He is a professor of pediatrics and division head of dermatology at Seattle Children’s Hospital and the University of Washington, Seattle.

“AD and MF are easily confused for one another at baseline,” explained Dr. Sidbury, who was not involved with the study or editorial. “Dupilumab is known to make AD better and theoretically could help MF via its effect on interleukin (IL)–13, yet case reports of exacerbation and/or unmasking of MF are out there.”

For the study, researchers retrospectively examined records of 530 patients with AD treated with dupilumab at the University Medical Center Utrecht (the Netherlands). Reviewing pretreatment biopsies revealed that among 14 (2.6%) patients who developed clinical suspicion of cutaneous T-cell lymphoma (CTCL) while on treatment, three actually had preexisting MF.

All 14 patients with LR initially responded to dupilumab then developed worsening symptoms at a median of 4 months. Patients reported that the worsening lesions looked and felt different than did previous lesions, with symptoms including burning/pain and an appearance of generalized erythematous maculopapular plaques, sometimes with severe lichenification, on the lower trunk and upper thighs.

The 14 patients’ posttreatment biopsies showed an atypical lymphoid infiltrate with lichenoid or perivascular distribution and intraepithelial T-cell lymphocytes. Whereas patients with MF had hyperconvoluted cerebriform lymphocytes aligned in the epidermal basal layer at the dermoepidermal junction, the 11 with LR had similar-looking lesions dispersed throughout the upper epidermis.

Immunohistochemically, both groups had a dysregulated (mostly increased) CD4:CD8 ratio. CD30 overexpression, usually absent in early-stage MF, affected only patients with LR and one patient with advanced MF. In addition, patients with LR maintained pan–T-cell antigens (CD2, CD3, and CD5), whereas those with MF did not. The 11 patients with LR experienced biopsy-confirmed resolution once they discontinued dupilumab.

It is reassuring that the LRs resolved after dupilumab discontinuation, writes the author of the accompanying editorial, Joan Guitart, MD, chief of dermatopathology at Northwestern University. Nevertheless, he added, such patients deserve “a comprehensive workup including skin biopsy with T-cell receptor clonality assay, blood cell counts with flow cytometry analysis, serum lactate dehydrogenase, and documentation of possible adenopathy, followed with imaging studies and/or local biopsies in cases with abnormal results.”

The possibility that these LRs may represent a first step toward lymphoma requires dermatologists to remain vigilant in ruling out MF, Dr. Guitart wrote, particularly in atypical presentations such as adult-onset AD, cases lacking a history of AD, and cases involving erythrodermic and other uncharacteristic presentations such as plaques, nodules, or spared flexural sites.

For dermatopathologists, Dr. Guitart recommended a cautious approach that resists overdiagnosing MF and acknowledging that insufficient evidence exists to report such reactions as benign. The fact that one study patient had both MF and LR raises concerns that the LR may not always be reversible, Dr. Guitart added.

Clinicians and patients must consider the possibility of dupilumab-induced LR as part of the shared decision-making process and risk-benefit calculus, Dr. Sidbury said. In cases involving unexpected responses or atypical presentations, he added, clinicians must have a low threshold for stopping dupilumab.

For patients who must discontinue dupilumab because of LR, the list of treatment options is growing. “While more investigation is required to understand the role of newer IL-13–blocking biologics and JAK inhibitors among patients experiencing lymphoid reactions,” said Dr. Chovatiya, “traditional atopic dermatitis therapies like narrowband UVB phototherapy and the oral immunosuppressant methotrexate may be reassuring in this population.” Conversely, cyclosporine has been associated with progression of MF.

Also reassuring, said Dr. Sidbury and Dr. Chovatiya, is the rarity of LR overall. Dr. Sidbury said, “The numbers of patients in whom LR or onset/exacerbation of MF occurs is extraordinarily low when compared to those helped immeasurably by dupilumab.”

Dr. Sidbury added that the study and accompanying editorial also will alert clinicians to the potential for newer AD biologics that target solely IL-13 and not IL-4/13, as dupilumab does. “If the deregulated response leading to LR and potentially MF in the affected few is driven by IL-4 inhibition,” he said, “drugs such as tralokinumab (Adbry), lebrikizumab (once approved), and perhaps other newer options might calm AD without causing LRs.”

(Lebrikizumab is not yet approved. In an Oct. 2 press release, Eli Lilly and Company, developer of lebrikizumab, said that it would address issues the U.S. Food and Drug Administration had raised about a third-party manufacturing facility that arose during evaluation of the lebrikizumab biologic license application.)

Study limitations include the fact that most patients who experienced LR had already undergone skin biopsies before dupilumab treatment, which suggests that they had a more atypical AD presentation from the start. The authors add that their having treated all study patients in a tertiary referral hospital indicates a hard-to-treat AD subpopulation.

Study authors reported relationships with several biologic drug manufacturers including Sanofi and Regeneron (dupilumab), LEO Pharma (tralokinumab), and Eli Lilly (lebrikizumab). However, none of these companies provided support for the study.

Dr. Sidbury has been an investigator for Regeneron, Pfizer, and Galderma and a consultant for LEO Pharma and Eli Lilly. Dr. Chovatiya has served as an advisor, consultant, speaker, and investigator for Sanofi and Regeneron. Dr. Guitart reported no conflicts of interest.

Nemolizumab is gearing up to be a potential new treatment for prurigo nodularis, with further phase 3 data supporting its efficacy and safety reported at the annual Congress of the European Academy of Dermatology and Venereology.

In the OLYMPIA 1 study, clinically significant improvements in both itch and skin lesions were seen after 16 weeks of treatment with nemolizumab compared with placebo (P < .0001).

Indeed, among the 286 patients who participated in the trial (190 on nemolizumab and 96 on placebo), 58.4% of those treated with nemolizumab and 16.7% of those who received placebo had an improvement of 4 points or more in the weekly average peak pruritus numeric rating scale (PP-NRS) at week 16 (P < .0001).

Skin lesions were assessed using an investigators general assessment (IGA) score, where IGA success was defined as a score of 0/1 indicating clear or almost clear skin or where there had been at least a 2-point change from baseline values. Over a quarter (26.3%) of nemolizumab-treated patients met these criteria versus 7.3% for those on placebo (P = .0001).

“These results confirm the results of the OLYMPIA 2 study, the other phase 3 study, and now I hope you understand why we are so excited,” lead investigator Sonja Ständer, MD, of the Center for Chronic Pruritus at University Hospital Münster, Germany, said at the meeting, where she presented the data.

The OLYMPIA 2 study included 274 patients and the results showed a weekly average PP-NRS score improvement of 56.3% vs. 20.9% for placebo and IGA success in 37.7% and 11% of patients, respectively, at 16 weeks.
 

First-in-class therapy

“We know how difficult it is to treat patients; they are refractory to treatment, frustrated, and this really impacts them regarding their quality of life,” said Dr. Ständer. New options are needed to help patients, and nemolizumab, a first-in-class interleukin-31 (IL-31) receptor alpha antagonist, is one treatment that may answer this call.

Prurigo nodularis is a chronic neuroimmune skin condition characterized by severe itch and multiple nodular skin lesions, Dr. Ständer explained. She added that there is evidence that IL-31 has a key role to play in the development of itch, and in differentiation of keratinocytes, type 2 and type 17 immune responses, and fibrosis associated with the condition.

The OLYMPIA 1 and 2 trials are part of a large developmental program that includes two ongoing trials. One is assessing the durability of response over 24 weeks in 40 patients and the other is a long-term extension trial involving 450 patients from the OLYMPIA 1 and 2 trials.
 

Inclusion criteria and additional results

For inclusion in the study, adults with prurigo nodularis for at least 6 months had to have 20 or more nodules on the body with a bilateral distribution, an IGA score of 3 or more, and an average PP-NRS of 7 or higher. The latter “was really a high bar for them to qualify for the trial,” said Dr. Ständer.

After an initial 4-week screening period, patients were randomly assigned to 24 weeks of treatment with nemolizumab or placebo given as a subcutaneous injection every 4 weeks. An 8-week “off-treatment” period followed.

The nemolizumab dose was based on the patient’s body weight, with patients weighing less than 90 kg (198 pounds) getting a loading dose of 60 mg followed by further doses of 30 mg; while patients weighing 90 kg or more receiving 50 mg of nemolizumab. 

Dr. Ständer reported that nemolizumab met all of the trials’ secondary endpoints; this included at least a 4-point improvement in sleep disturbance. She noted that changes in itch and subsequent sleep disturbance occurred early, at 4 weeks of treatment – after just one injection of nemolizumab.

The response rates seen in the moderate to severe prurigo nodularis population studies are quite unique when compared with conventional therapies, Dr. Ständer maintained. “We’ve never seen something like this before.”
 

No safety concerns

No significant difference in tolerability was seen between the nemolizumab and placebo groups, Dr. Ständer observed. Any adverse event occurred in 71.7% and 65.3% of patients, respectively, and serious adverse events in 8.6% and 10.5%.

There was a similar rate of adverse events leading to discontinuation, respectively (4.8% vs. 4.2%).

Headache was seen more frequently among those on nemolizumab than those on placebo (7.0% vs. 2.1%), and there was a higher number of eczema cases among those on nemolizumab (5.3% vs. 1.1%). The latter is somewhat paradoxical because nemolizumab is also being studied as a treatment for atopic dermatitis, with good results seen in phase 3 trials. Asked about this finding after her presentation, Dr. Ständer said “we are following up on that to know exactly what is going on; this is a side effect of nemolizumab that is seen also with other biologics.”
 

JAK inhibitor trial for PN, CPUO

Nemolizumab is not the only promising new approach to treating prurigo nodularis. During a separate late-breaking news session at the meeting, Shawn Kwatra, MD, director of the Johns Hopkins Itch Center in Baltimore, presented “dramatic” data from a “proof-of-concept” phase 2 study with the Janus kinase (JAK) inhibitor abrocitinib (Cibinqo), which is approved for atopic dermatitis in the United States and Europe.

The investigator-initiated trial took a different approach from most other trials, Dr. Kwatra said. The starting point was to look at studying multiple rather than single dermatologic diseases that were perhaps being left a little by the wayside but may share some common ground. Those two diseases were prurigo nodularis and chronic pruritus of unknown origin (CPUO).

“They’re actually very analogous conditions in the way we treat, so I thought those would be a good pair,” Dr. Kwatra said, noting that there were several studies that made him think that JAK inhibition “would be an interesting concept to try.”

On that basis, 10 women with prurigo nodularis (mean age, 58 years) and two women and eight men with CPUO (mean age, 70 years) were recruited and all were treated with abrocitinib at a once-daily oral dose of 200 mg for 12 weeks.

“They all had really intense itch,” before treatment, Dr. Kwatra said. The mean baseline PP-NRS was 9.2 and 8.2 in the prurigo nodularis and CPUO groups, respectively. By the end of treatment, however, “the improvement in itch was pretty dramatic,” especially for prurigo nodularis, he said.

At 12 weeks, the PP-NRS score had fallen to 2.0 in the prurigo nodularis group, equating to a significant 78% change from baseline (P < .001). And, in the CPUO group, the 12-week PP-NRS score was 3.8, nearly a 54% drop from baseline (P = .01).

Sleep disturbance was improved for both conditions, and in the patients with prurigo nodularis, there were improvements in skin lesions. Looking at the patients who responded to treatment, Dr. Kwatra noted that “if you responded, you respond fast, and you respond almost entirely.”

Additional findings from cutaneous transcriptome analysis showed that JAK inhibition with abrocitinib was modulating Th1-, Th2-, Th17-, and Th22-mediated pathways in both groups of patients.

The overall frequency of adverse events was low, and no serious adverse events occurred.

Commenting on the potential use of abrocitinib in managing patients with PN and CPUO, Tiago dos Reis Matos, MD, PhD, MSc, Amsterdam University Medical Centers, told this news organization that JAK1 inhibitors “are showing promising results in treating several diseases.”

Dr. Matos, who was not involved in the study, added that JAK inhibition was “of special interest in prurigo nodularis and chronic pruritus, since these are some of the most difficult diseases to treat with limited therapeutic options.”

Dr. Kwatra observed: “Obviously, we need further development. But we also have clues here about how to design phase 3 trials.”

Galderma funded the OLYMPIA 1 and 2 studies. Dr. Ständer was an investigator for the trial and reported serving as a consultant, speaker, or investigator for multiple pharmaceutical companies, including Galderma.

Johns Hopkins University supported the abrocitinib study with funding from Pfizer. Dr. Kwatra is an advisory board member or consultant to several pharmaceutical companies and is an investigator for Galderma, Incyte, Pfizer, and Sanofi.

Nemolizumab is gearing up to be a potential new treatment for prurigo nodularis, with further phase 3 data supporting its efficacy and safety reported at the annual Congress of the European Academy of Dermatology and Venereology.

In the OLYMPIA 1 study, clinically significant improvements in both itch and skin lesions were seen after 16 weeks of treatment with nemolizumab compared with placebo (P < .0001).

Indeed, among the 286 patients who participated in the trial (190 on nemolizumab and 96 on placebo), 58.4% of those treated with nemolizumab and 16.7% of those who received placebo had an improvement of 4 points or more in the weekly average peak pruritus numeric rating scale (PP-NRS) at week 16 (P < .0001).

Skin lesions were assessed using an investigators general assessment (IGA) score, where IGA success was defined as a score of 0/1 indicating clear or almost clear skin or where there had been at least a 2-point change from baseline values. Over a quarter (26.3%) of nemolizumab-treated patients met these criteria versus 7.3% for those on placebo (P = .0001).

“These results confirm the results of the OLYMPIA 2 study, the other phase 3 study, and now I hope you understand why we are so excited,” lead investigator Sonja Ständer, MD, of the Center for Chronic Pruritus at University Hospital Münster, Germany, said at the meeting, where she presented the data.

The OLYMPIA 2 study included 274 patients and the results showed a weekly average PP-NRS score improvement of 56.3% vs. 20.9% for placebo and IGA success in 37.7% and 11% of patients, respectively, at 16 weeks.
 

First-in-class therapy

“We know how difficult it is to treat patients; they are refractory to treatment, frustrated, and this really impacts them regarding their quality of life,” said Dr. Ständer. New options are needed to help patients, and nemolizumab, a first-in-class interleukin-31 (IL-31) receptor alpha antagonist, is one treatment that may answer this call.

Prurigo nodularis is a chronic neuroimmune skin condition characterized by severe itch and multiple nodular skin lesions, Dr. Ständer explained. She added that there is evidence that IL-31 has a key role to play in the development of itch, and in differentiation of keratinocytes, type 2 and type 17 immune responses, and fibrosis associated with the condition.

The OLYMPIA 1 and 2 trials are part of a large developmental program that includes two ongoing trials. One is assessing the durability of response over 24 weeks in 40 patients and the other is a long-term extension trial involving 450 patients from the OLYMPIA 1 and 2 trials.
 

Inclusion criteria and additional results

For inclusion in the study, adults with prurigo nodularis for at least 6 months had to have 20 or more nodules on the body with a bilateral distribution, an IGA score of 3 or more, and an average PP-NRS of 7 or higher. The latter “was really a high bar for them to qualify for the trial,” said Dr. Ständer.

After an initial 4-week screening period, patients were randomly assigned to 24 weeks of treatment with nemolizumab or placebo given as a subcutaneous injection every 4 weeks. An 8-week “off-treatment” period followed.

The nemolizumab dose was based on the patient’s body weight, with patients weighing less than 90 kg (198 pounds) getting a loading dose of 60 mg followed by further doses of 30 mg; while patients weighing 90 kg or more receiving 50 mg of nemolizumab. 

Dr. Ständer reported that nemolizumab met all of the trials’ secondary endpoints; this included at least a 4-point improvement in sleep disturbance. She noted that changes in itch and subsequent sleep disturbance occurred early, at 4 weeks of treatment – after just one injection of nemolizumab.

The response rates seen in the moderate to severe prurigo nodularis population studies are quite unique when compared with conventional therapies, Dr. Ständer maintained. “We’ve never seen something like this before.”
 

No safety concerns

No significant difference in tolerability was seen between the nemolizumab and placebo groups, Dr. Ständer observed. Any adverse event occurred in 71.7% and 65.3% of patients, respectively, and serious adverse events in 8.6% and 10.5%.

There was a similar rate of adverse events leading to discontinuation, respectively (4.8% vs. 4.2%).

Headache was seen more frequently among those on nemolizumab than those on placebo (7.0% vs. 2.1%), and there was a higher number of eczema cases among those on nemolizumab (5.3% vs. 1.1%). The latter is somewhat paradoxical because nemolizumab is also being studied as a treatment for atopic dermatitis, with good results seen in phase 3 trials. Asked about this finding after her presentation, Dr. Ständer said “we are following up on that to know exactly what is going on; this is a side effect of nemolizumab that is seen also with other biologics.”
 

JAK inhibitor trial for PN, CPUO

Nemolizumab is not the only promising new approach to treating prurigo nodularis. During a separate late-breaking news session at the meeting, Shawn Kwatra, MD, director of the Johns Hopkins Itch Center in Baltimore, presented “dramatic” data from a “proof-of-concept” phase 2 study with the Janus kinase (JAK) inhibitor abrocitinib (Cibinqo), which is approved for atopic dermatitis in the United States and Europe.

The investigator-initiated trial took a different approach from most other trials, Dr. Kwatra said. The starting point was to look at studying multiple rather than single dermatologic diseases that were perhaps being left a little by the wayside but may share some common ground. Those two diseases were prurigo nodularis and chronic pruritus of unknown origin (CPUO).

“They’re actually very analogous conditions in the way we treat, so I thought those would be a good pair,” Dr. Kwatra said, noting that there were several studies that made him think that JAK inhibition “would be an interesting concept to try.”

On that basis, 10 women with prurigo nodularis (mean age, 58 years) and two women and eight men with CPUO (mean age, 70 years) were recruited and all were treated with abrocitinib at a once-daily oral dose of 200 mg for 12 weeks.

Additional data from the phase 3 EASE study conducted in patients with epidermolysis bullosa (EB) show that regular application of the topical gel Oleogel-S10 (Filsuvez) is associated with a reduced need for daily dressing changes when compared with a control gel.

In a final, post hoc analysis to come from the trial, 15 of 45 (33%) patients treated with Oleogel-S10 versus 5 of 48 (10.4%) treated with the control gel were reported as no longer needing daily dressing changes at 45 days of follow-up.

Moreover, the effect was sustained, with similar percentages of patients no longer requiring daily dressing changes at 60 days (34% vs. 13%, respectively) and 90 days (36% vs. 11%) of follow-up.

The mean reduction in daily dressing changes was 1.36 for Oleogel-S10 and 0.41 for the control gel (P = .005).

“Patients who, in the beginning, had daily dressing changes had almost three fewer dressing changes every 2 weeks if they were treated with Oleogel-S10,” Dimitra Kiritsi, MD, PhD, of the department of dermatology at the University of Freiburg (Germany), reported at the annual congress of the European Academy of Dermatology and Venereology. By comparison, patients in the control group had just one fewer daily dressing change in 2 weeks.

“You might say okay, but what does this mean in terms of time?” added Dr. Kiritsi. Using historical data on the time required for whole body care (Orphanet J Rare Dis. 2020 Jan 3. doi: 10.1186/s13023-019-1279-y), it was estimated that treatment with Oleogel-S10 was associated with an overall time-saving per week of 11 hours (6.6 hours for the patient and 4.4 hours for the caregiver) and use of the control gel was associated with an overall time-saving of 4 hours (2.4 hours for the patient and 1.6 hours for the caregiver).

“This is, for our patients, important,” said Dr. Kiritsi, as “it is time that they can spend doing something nice with the family” instead, avoiding the pain and distress associated with frequent dressing changes.

Approved in Europe, not in the United States

Oleogel-S10, classified as an herbal product, contains triterpenes derived from birch bark extract, which have been formulated with sunflower oil to form a gel.

Despite being approved for use in Europe, Oleogel-S10 has not yet been approved to treat EB in the United States. The FDA did not approve Amryt Pharma’s new drug application in February 2022. The application had included data from the EASE trial.

EASE included 223 patients with dystrophic or junctional EB, including 156 children, at 58 sites in 28 countries. As such, this makes it the largest treatment study in this rare genetic disease to date.

The trial had consisted of an initial 90-day, double-blind treatment period, during which time 109 patients had used Oleogel-S10 and 114 had used a control gel. This was followed by a 24-month open-label phase, during which time all remaining patients (n = 205) had used Oleogel-S10 on top of their standard of care.

Dr. Kiritsi summarized the main results of the EASE trial as follows.

• Complete healing of target wounds (primary endpoint) in 41.3% of patients treated with Oleogel-S10 and 28.9% of patients treated with the control gel (P = .013).
• Improved total body wound burden measured by both Epidermolysis Bullosa Disease Activity and Scarring Index and Body Surface Area Percentage scores.
• Reduced frequency of dressing changes (1 less per 2 weeks for Oleogel-S10 versus 0 less per 2 weeks for control gel).
• Improved pain among participants aged 4 years and older while their dressings were being changed.
• Reduced rates of wound infection (0.9% Oleogel-S10 vs. 4.4% control gel).
• Similar rates of treatment-emergent adverse events (24.8% vs. 22.8%, respectively), which were mostly deemed to be mild or moderate.

The EASE study – an important trial for EB

EASE is an important trial for EB, the study’s principal investigator Dédée Murrell, MD, DSc, University of New South Wales, Sydney, has pointed out previously.

“This was the first EB study to meet its primary endpoint and demonstrated a statistically significant acceleration of target wound healing by day 45,” Dr. Murrell said in a press release issued by Amryt Pharma to coincide with the online publication of the trial results.

“In addition, the favorable trends we see with key secondary endpoints such as reduced wound burden, pain, and frequency of dressing changes are considered as being very meaningful for patients,” Dr. Murrell said.

The EASE study was funded by Amryt Research Limited. Dr. Kiritsi reported receiving honoraria or consultation fees from Amryt, RHEACELL GmbH, and Fibrx Derm. She also acknowledged grant or research support from DEBRA International, EB Research Partnership, Fritz-Thyssen Foundation, German Research Foundation, and RHEACELL. Dr. Murrell has ties to Amryt and Amicus and is a co-owner of the patent for topical sirolimus for EB simplex.

EASE included 223 patients with dystrophic or junctional EB, including 156 children, at 58 sites in 28 countries. As such, this makes it the largest treatment study in this rare genetic disease to date.

The trial had consisted of an initial 90-day, double-blind treatment period, during which time 109 patients had used Oleogel-S10 and 114 had used a control gel. This was followed by a 24-month open-label phase, during which time all remaining patients (n = 205) had used Oleogel-S10 on top of their standard of care.

Dr. Kiritsi summarized the main results of the EASE trial as follows.

• Complete healing of target wounds (primary endpoint) in 41.3% of patients treated with Oleogel-S10 and 28.9% of patients treated with the control gel (P = .013).
• Improved total body wound burden measured by both Epidermolysis Bullosa Disease Activity and Scarring Index and Body Surface Area Percentage scores.
• Reduced frequency of dressing changes (1 less per 2 weeks for Oleogel-S10 versus 0 less per 2 weeks for control gel).
• Improved pain among participants aged 4 years and older while their dressings were being changed.
• Reduced rates of wound infection (0.9% Oleogel-S10 vs. 4.4% control gel).
• Similar rates of treatment-emergent adverse events (24.8% vs. 22.8%, respectively), which were mostly deemed to be mild or moderate.

The EASE study – an important trial for EB

EASE is an important trial for EB, the study’s principal investigator Dédée Murrell, MD, DSc, University of New South Wales, Sydney, has pointed out previously.

“This was the first EB study to meet its primary endpoint and demonstrated a statistically significant acceleration of target wound healing by day 45,” Dr. Murrell said in a press release issued by Amryt Pharma to coincide with the online publication of the trial results.

“In addition, the favorable trends we see with key secondary endpoints such as reduced wound burden, pain, and frequency of dressing changes are considered as being very meaningful for patients,” Dr. Murrell said.

The EASE study was funded by Amryt Research Limited. Dr. Kiritsi reported receiving honoraria or consultation fees from Amryt, RHEACELL GmbH, and Fibrx Derm. She also acknowledged grant or research support from DEBRA International, EB Research Partnership, Fritz-Thyssen Foundation, German Research Foundation, and RHEACELL. Dr. Murrell has ties to Amryt and Amicus and is a co-owner of the patent for topical sirolimus for EB simplex.

A recent survey found that less than half of pharmacies in the Washington area had a 30-day supply of either 2.5-mg or 10-mg tablets of oral minoxidil, used for both hair loss and hypertension.

Patients are not finding out until they go to pick up their prescription, which can result in an interruption of treatment – and, potentially a loss of hard-earned hair gain, said Adam Friedman, MD, professor and chair of dermatology at George Washington University, Washington, who was the lead author of the survey, published online on Oct. 26 as a research letter in the Journal of Drugs in Dermatology.

Going off low-dose oral minoxidil may spark a telogen effluvium event, and that is very disappointing to patients, Dr. Friedman told this news organization.

“There needs to be some system that alerts us,” he said. “Even if it’s a minor shortage, just so we’re aware. We can then prepare patients,” he added, noting that it would be better for someone to be taking a lower-than-normal dose rather than no medication at all while they wait for a refill.

Minoxidil has long been approved in a topical formulation to treat androgenetic alopecia, but a low-dose oral form has gained currency in the wake of findings that it might more effectively treat hair loss, and is without side effects. A New York Times article in August 2022 touting low-dose oral minoxidil as a cheap and effective hair loss drug appeared to ignite interest in this option. In May, 2023, researchers reporting in JAMA Network Open demonstrated a significant uptick in prescriptions for oral minoxidil in the wake of the article’s publication.

Oral minoxidil is approved by the Food and Drug Administration only for hypertension, but dermatologists are prescribing it off-label at a lower dose for hair loss. Dr. Friedman said it’s not clear whether the shortages his team found are national in scope, or whether they are a result of increased demand, or other factors.

After several patients told him they were having trouble filling minoxidil prescriptions, and colleagues said they’d had patients with similar experiences, Dr. Friedman and his colleagues undertook the survey. In the first week of October 2023, they contacted 277 pharmacies by phone in Washington and surrounding Virginia and Maryland counties. The pharmacies were CVS, Giant, Walgreens, and Harris Teeter.

Of the 277 pharmacies they contacted, 40% (111) reported availability of 2.5-mg tablets for a 30-day supply, and just under 30% (82) reported having 10-mg tablets for a 30-day supply.

For treating hair loss, most patients are prescribed 2.5-mg pills, with starting doses ranging from 0.625 mg to 5 mg twice a day, Dr. Friedman said. The 10-mg dose is more frequently prescribed for hypertension.

Only 28% (19 of 67) of the Maryland pharmacies had 30-day supplies of 2.5-mg tablets on hand, and just 22% (15) of the Maryland pharmacies had 30-day supplies of 10-mg tablets. In Northern Virginia, 44% (63 of 143) of the pharmacies had 30-day supplies of the 2.5 mg tablets, as did just 43% (29 of 67) of the Washington pharmacies.

Dr. Friedman said he has started giving patients paper prescriptions they can use to shop around, rather than electronically sending a prescription to a particular pharmacy.

Neither the Food and Drug Administration nor the American Society of Health System Pharmacists lists oral minoxidil as a drug in shortage.

Michael Ganio, PharmD, senior director of pharmacy practice and quality for ASHP, said the organization received a report from wholesalers in mid-September showing spotty oral minoxidil availability, with the drug on backorder with some manufacturers.  ASHP's shortages list is compiled from reports from physicians, manufacturers and wholesalers, he said.

Under what he calls "blue sky conditions," pharmacies using a just-in-time inventory model should be able to fill prescriptions within hours or days, which might explain why some pharmacies in the Washington, DC area survey did not have a 30-day supply on hand, he said. However, Dr. Ganio noted that the causes of drug shortages are complex and multi-factorial. For now, he said there have been no oral minoxidil shortage reports since mid-September.

But Dr. Friedman said some of his patients have waited weeks for a new supply – and that no one is aware of the problem until the last moment.

The lack of alerts or transparency “also erodes the physician-patient relationship because there’s this expectation of the patient that we should have known this,” said Dr. Friedman.

Dr. Friedman reports no relevant financial relationships.

A new artificial intelligence (AI) model can detect the deadliest skin cancer with 100% accuracy, highlighting the rapid improvement of AI in medicine, say researchers from the United Kingdom. AI detected more than 99% of all skin cancers.

The researchers tested the AI by integrating it into a clinical diagnosis process – anticipating a future in which AI helps doctors catch skin cancer faster and triage patients.

Skin cancer is the most common cancer in the United States;  one in five 5 Americans develop skin cancer by age 70. With melanoma, the deadliest skin cancer, the 5-year survival rate is better than 99% if caught early, though only about three-quarters of melanomas are caught at this stage.

Amid rising skin cancer rates come concerns that the number of dermatologists in the workforce isn’t keeping pace. That may be why the average wait time for a dermatology appointment is trending up – in 2022, it reached 34.5 days.

The study, which was presented at the European Academy of Dermatology and Venereology Congress recently and has not yet been published, involved 6,900 patients in the United Kingdom with suspected skin cancer. The patients had been referred by their primary care physicians. The researchers took images of the suspicious areas and uploaded them to the AI software. The AI’s assessment was then shared with a dermatologist.

“Note that the diagnosis issued by the AI was not hidden from the dermatologist doing the second assessment,” said lead researcher Kashini Andrew, MBBS, a dermatologist and specialist registrar at University Hospitals Birmingham NHS Foundation Trust.

Dr. Andrew acknowledged that this may have influenced the dermatologist’s opinion. But that’s the vision of how doctors could use this tool.

The AI caught 59 of 59 melanomas and 189 of 190 total skin cancers (99.5%). (The one case that the AI missed was caught by the dermatologist.) It also flagged 541 of 585 precancerous lesions (92.5%). This represented a big improvement from a 2021 version of the model, which detected 86% of melanomas, 84% of all skin cancers, and 54% of precancerous lesions.

Over the 10-month period of the study, the system saved more than 1,000 face-to-face consultations, freeing dermatologists’ time to catch more cancers and serve more patients.

Limitations

The patients in the study were from “one hospital in a single region of the UK,” and the sample was not large enough to allow broad statements to be made about the use of AI in dermatology, Dr. Andrew said.

But it can open the conversation. Roxana Daneshjou, MD, PhD, a dermatologist at Stanford (Calif.) University who has studied the pros and cons of AI in medicine, had some concerns. For one thing, doctors can gather more in-depth information during an in-person exam than AI can glean from a photo, Dr. Daneshjou noted. They can examine skin texture, gather patient history, and take photos with special lighting and magnification.

And the AI needs to get better at ruling out malignancy, Dr. Daneshjou said. In this study, the AI identified 75% of benign lesions, a decline from the earlier version. The researchers noted in the abstract that this is a potential trade-off for increased sensitivity.

“[Unnecessary] biopsies can clog up the health care system, cost money, and cause stress and scarring,” said Dr. Daneshjou. “You don’t want to increase the burden of that.”

Still, if AI software such as the kind used in the study proves just as accurate in larger, more diverse sample sizes, then it could be a powerful tool for triage, Dr. Daneshjou said. “If AI gets particularly good at finding malignancy and also ruling it out, that would be a win.”

The U.S. Food and Drug Administration has approved ustekinumab-auub (Wezlana) as a biosimilar to ustekinumab (Stelara) for the treatment of multiple inflammatory conditions. This is the first approval for a ustekinumab biosimilar in the United States.

Ustekinumab-auub was also granted an interchangeability designation, meaning that, depending on state law, a pharmacist may substitute the biosimilar for the reference product without consulting the prescribing provider.

“Today’s approval exemplifies the FDA’s longstanding commitment to support a competitive marketplace for biological products,” Sarah Yim, MD, director of the Office of Therapeutic Biologics and Biosimilars in the FDA’s Center for Drug Evaluation and Research, said in a statement. “This approval can empower patients by helping to increase access to safe, effective, and high-quality medications at potentially lower cost.”

Ustekinumab, manufactured by Johnson & Johnson, targets interleukin-12 and IL-23 and was first approved in 2009. Ustekinumab-auub was developed by Amgen.

Ustekinumab-auub is approved for the treatment of adult patients with moderate to severe plaque psoriasis who are candidates for phototherapy or systemic therapy, active psoriatic arthritis, moderate to severely active Crohn’s disease, and moderate to severely active ulcerative colitis. It is also approved for pediatric patients aged 6 years and older with moderate to severe plaque psoriasis who are candidates for phototherapy or systemic therapy and active psoriatic arthritis.

The approval was based on “comprehensive review of scientific evidence,” including “comparisons of the products on an analytical level using an extensive battery of chemical and biological tests and biological assays that confirmed similarity in the structural and functional features of Wezlana and Stelara (including those known to impact safety and efficacy), and comparative human pharmacokinetic data, clinical immunogenicity data, and other clinical safety and effectiveness data,” the FDA said.

Some common side effects of ustekinumab-auub include nasopharyngitis, upper respiratory tract infection, headache, fatigue, and nausea. The most severe side effect of the biosimilar, as with the reference drug ustekinumab, is infection.

The product launch of ustekinumab-auub will be delayed as a part of a settlement of Johnson & Johnson’s lawsuit against Amgen, according to Reuters. The details of the settlement are confidential, but it was stated that the biosimilar would be available by Jan. 1, 2025.

Ustekinumab-auub is approved for the treatment of adult patients with moderate to severe plaque psoriasis who are candidates for phototherapy or systemic therapy, active psoriatic arthritis, moderate to severely active Crohn’s disease, and moderate to severely active ulcerative colitis. It is also approved for pediatric patients aged 6 years and older with moderate to severe plaque psoriasis who are candidates for phototherapy or systemic therapy and active psoriatic arthritis.

The approval was based on “comprehensive review of scientific evidence,” including “comparisons of the products on an analytical level using an extensive battery of chemical and biological tests and biological assays that confirmed similarity in the structural and functional features of Wezlana and Stelara (including those known to impact safety and efficacy), and comparative human pharmacokinetic data, clinical immunogenicity data, and other clinical safety and effectiveness data,” the FDA said.

Some common side effects of ustekinumab-auub include nasopharyngitis, upper respiratory tract infection, headache, fatigue, and nausea. The most severe side effect of the biosimilar, as with the reference drug ustekinumab, is infection.

The product launch of ustekinumab-auub will be delayed as a part of a settlement of Johnson & Johnson’s lawsuit against Amgen, according to Reuters. The details of the settlement are confidential, but it was stated that the biosimilar would be available by Jan. 1, 2025.

The U.S. Food and Drug Administration has approved secukinumab for adults with moderate to severe hidradenitis suppurativa (HS).

The development, which was announced Oct. 31, makes secukinumab the first and only interleukin (IL)–17A inhibitor approved by the FDA for HS, which affects an estimated 1% of the worldwide population. It joins the tumor necrosis factor blocker adalimumab as the only FDA-approved treatment options for HS.

Secukinumab (Cosentyx) was previously approved by the FDA for treatment of  moderate-to-severe plaque psoriasis in adults, and several other indications including psoriatic arthritis and ankylosing spondylitis.

Approval for HS was based on the pivotal phase 3 SUNSHINE and SUNRISE trials, which had a combined enrollment of more than 1,000 patients with HS in 40 countries. The studies evaluated efficacy, safety, and tolerability of two dose regimens of the drug in adults with moderate to severe HS at 16 weeks and up to 52 weeks.

According to a press release from Novartis announcing the approval, results at week 16 showed that a significantly higher proportion of patients achieved a Hidradenitis Suppurativa Clinical Response (HiSCR) when treated with secukinumab 300 mg every 2 weeks, compared with placebo: 44.5% vs. 29.4%, respectively, in the SUNSHINE trial and 38.3.% vs. 26.1% in the SUNRISE trial (P < .05 for both associations).

Similarly, results at week 16 showed that a significantly higher proportion of patients achieved an HiSCR when treated with secukinumab 300 mg every 4 weeks, compared with placebo: 41.3% vs. 29.4% in the SUNSHINE trial and 42.5% vs. 26.1% in the SUNRISE trial (P < .05 for both associations).

In addition, in an exploratory analysis out to 52 weeks, HiSCR values observed at week 16 following either dose regimen of secukinumab were improved over time up to week 52. In SUNSHINE, the values improved by 56.4% in patients treated with secukinumab every 3 weeks and by 56.3% in those treated with secukinumab every 4 weeks. In SUNRISE, the values improved by 65% in patients who were treated with secukinumab every 2 weeks and by 62.2% in those who were treated with the drug every 4 weeks.

In an interview, Haley Naik, MD, a dermatologist who directs the hidradenitis suppurativa program at the University of California, San Francisco, characterized the approval as a win for HS patients. “Patients now not only have a second option for approved therapy for HS, but also an option that raises the bar for what we can expect from therapeutic response,” she told this news organization. “I am excited to see a novel therapy that improves HS and quality of life for patients make it through the regulatory pipeline.”

Dr. Naik disclosed that she has received grant support from AbbVie; consulting fees from 23andme, AbbVie, Aristea Therapeutics, Nimbus Therapeutics, Medscape, Sonoma Biotherapeutics, DAVA Oncology, Boehringer Ingelheim, Union Chimique Belge, and Novartis; investigator fees from Pfizer; and holds shares in Radera. She is also an associate editor for JAMA Dermatology and a board member of the Hidradenitis Suppurativa Foundation.
