A simple skin biopsy test is able to detect an abnormal form of alpha-synuclein with high accuracy in individuals with neurodegenerative disorders such as Parkinson’s disease (PD).

Researchers are hopeful that the test — which identified phosphorylated alpha-synuclein (P-SYN) with 95.5% accuracy in the blinded, multicenter trial — will accelerate not just early identification of synucleinopathies but also drug development.

Synucleinopathies include PD, dementia with Lewy bodies (DLB), multiple system atrophy (MSA), and pure autonomic failure (PAF).

“Each year, there are nearly 200,000 people in the U.S. who face a diagnosis of Parkinson’s disease, dementia with Lewy bodies, and related disorders,” study investigator Christopher H. Gibbons, MD, professor of neurology at Harvard Medical School in Boston, said in a press release.

He explained that patients often experience delays in diagnosis or are misdiagnosed due to the complexity of synucleinopathies.

“With a simple, minimally invasive skin biopsy test, this blinded, multicenter study demonstrated how we can more objectively identify the underlying pathology of synucleinopathies and offer better diagnostic answers and care for patients.”

The findings were published online on March 20 in JAMA.
 

An Urgent Priority

Affecting an estimated 2.5 million people in the United States, synucleinopathies are progressive neurodegenerative diseases with varying prognoses, so identifying a reliable diagnostic biomarker is an “urgent unmet priority,” the researchers noted.

The disorders share some symptoms such as tremors and cognitive changes, and all are characterized by P-SYN, an abnormal protein found in the cutaneous nerve fibers.

The study included 428 adults aged 40-99 years (mean age, 70 years) recruited from 30 academic and community-based neurology practices across the United States, with 277 diagnosed with PD, DLB, MSA, or PAF. It also included a control group of 120 participants with no symptoms suggestive of synucleinopathy.

Investigators used the commercially available Syn-One Test, developed in 2019 by CND Life Sciences, to analyze levels of P-SYN via 3-mm punch skin biopsies from each participant.

The test detected P-SYN in 95.5% of study participants overall, including 89 of 96 (92.7%) with PD, 54 of 55 (98.2%) with MSA, 48 of 50 (96%) with DLB, 22 of 22 (100%) with PAF, and 4 of 120 (3.3%) of the controls with no synucleinopathy.

The investigators said it is possible that some of the controls who tested positive had a subclinical form of synucleinopathy, which would explain the false positives.

Study limitations include clinical consensus diagnostic criteria without video or autopsy confirmation, a lack of genetic testing on participants (some genetic forms of PD do not have alpha-synuclein deposition), and the fact that controls were younger than those in disease groups.

“Further research is needed in unselected clinical populations to externally validate the findings and fully characterize the potential role of skin biopsy detection of P-SYN in clinical care,” the authors wrote.

Syn-One is not approved by the US Food and Drug Administration as a diagnostic test for PD but is available as a pathologic assay that determines whether a tissue sample contains phosphorylated alpha-synuclein and can be billed through Medicare.

The study was funded by the National Institutes of Health. Dr. Gibbons reported having stock options in CND Life Sciences outside the submitted work. Other disclosures are noted in the original article.

Benzene Detected in Benzoyl Peroxide Products: Debate On Implications Continues

Article Type

Tue, 03/26/2024 - 10:54

 

Nine days after the independent laboratory Valisure petitioned the Food and Drug Administration (FDA) to recall acne products with benzoyl peroxide (BP) because of the lab’s findings of extremely high levels of the carcinogen benzene, it published another report in Environmental Health Perspectives (EHP), on March 14, also warning about BP acne products.

The bottom line was the same: The laboratory, based in New Haven, Connecticut, said its analyses raise substantial concerns about the safety of BP-containing acne products currently on the market.

The lab’s results showed that the products can form over 800 times the conditionally restricted FDA concentration limit of 2 parts per million (ppm) of benzene, with both prescription and over-the-counter products affected.

“This is a problem of degradation, not contamination,” David Light, CEO and founder of Valisure, said in a telephone interview. BP can decompose into benzene, and exposure to benzene has been linked with a higher risk for leukemia and other blood cancers, according to the American Cancer Society.

In the wake of the findings, however, debate has erupted over the method and approach used by Valisure to test these products, with critics and companies contending that more “real-world” use data are needed. And the US Pharmacopeia (USP) is asking for full transparency about the testing methods.

In a March 8 statement, USP said the petition indicated that modified USP methods were used in the study, noting that “if changes are made to a USP method, complete validation data is necessary to demonstrate that a product meets USP standards.”

However, Valisure contended that drug products need to demonstrate stability over the entire life cycle, from shipment to continued use, emphasizing that constitutes the best “real-world” approach. It also defended the methodology it used.

The reports have led to a state of uncertainty about the use of BP products.

“Right now, we have more unknowns than anything else,” John Barbieri, MD, MBA, assistant professor of dermatology at Harvard Medical School and director of the Advanced Acne Therapeutics Clinic at Brigham and Women’s Hospital, Boston, said in a video posted on X and YouTube, summarizing the findings released by Valisure on March 6 and 14. He was not involved in the Valisure research.

In a telephone interview, Dr. Barbieri said the report “needs to be taken seriously,” but he also believed the Valisure report is lacking information about testing under “real-world” conditions. He is calling for more information and more transparency about the data. What’s clear, Dr. Barbieri told this news organization, is that the findings about high benzene levels are not a manufacturing error. “It’s something to do with the molecule itself.”
 

Valisure’s Analyses

Valisure performed an initial analysis, using a method called gas chromatography-mass spectrometry, which is the FDA-preferred method for detecting benzene, Mr. Light said. It tested 175 acne products, 99 containing BP and 76 with other ingredients, such as salicylic acid. All the products without BP had no detectable benzene or values below 2 ppm, the FDA concentration limit for benzene.

Of the 99 BP products, 94 contained benzene without any elevated temperature incubation, according to Valisure. Using 50 °C (122 °F, the accepted pharmaceutical stability testing temperature) on 66 products, Valisure detected over 1500 ppm of benzene in two products, over 100 ppm in 17 products, and over 10 ppm in 42 products over an 18-day period.

The analysis confirmed, Valisure said in a press release and the petition, that a substantial amount of benzene can form in a BP product and leak outside the packaging into surrounding air.

The EHP paper, which includes authors from Valisure, reported that researchers took single lots of seven branded BP products, namely, Equate Beauty 2.5% BP cleansers, Neutrogena 10% BP cleanser, CVS Health 10% BP face wash, Walgreens 10% BP cream, Clean & Clear 10% cleanser, Equate Beauty 10% BP acne wash, and Proactiv 2.5% BP cleanser.

Using testing that involved gas chromatography-mass spectrometry, benzene was detected in all the BP products samples tested, and levels increased during incubation at body and shelf-life performance temperatures to more than 2 ppm. The authors concluded that the study “raises substantial concerns” about the safety of BP products currently on the market.
 

 

 

Methodology Debates

Two days after Valisure released its analysis on March 6, the USP reviewed the citizen’s petition filed by Valisure and called for more transparency around the testing methods.

“The petition referenced USP and indicated that modified USP methods and procedures were used in the study. The presence of unsafe levels of benzene should be taken seriously,” the statement said. The USP statement also noted that the Valisure analysis used modified USP methods and said that “if changes are made to a USP method, complete validation data is necessary to demonstrate that a product meets USP standards.”

In its statement, USP took issue with a practice known as accelerated thermal degradation, which it said Valisure used. USP said the approach involves raising the storage temperature of a product to higher than the temperature indicated on the label for the purpose of simulating degradation over a longer period. While the approach may be acceptable, USP said, the temperatures chosen may not be what is expected to happen to the products.

In response, Mr. Light of Valisure referenced guidance issued in August, 2020, from the FDA, stating that the method it used in the BP analysis can be used to detect impurities in hand sanitizers, including benzene. (In 2021, Valisure detected high levels of benzene in some hand sanitizers and asked the FDA to take action.)
 

Company Response

Among the companies that took issue with the report was Reckitt, which makes Clearasil, which contains BP. In a statement, the company said, in part: “The products and their ingredients are stable over the storage conditions described on their packaging which represent all reasonable and foreseeable conditions.” It said the findings presented by Valisure reflect “unrealistic scenarios rather than real-world conditions.”

The Personal Care Products Council, a national trade association that represents cosmetic and personal care product manufacturers, also took issue with the findings and the approach used to evaluate the products.
 

FDA and the Citizen’s Petition

The FDA accepted the petition, Mr. Light said, and gave it a docket number. “We’ll hopefully hear more soon” because the FDA is required to respond to a citizen’s petition within 180 days, he said.

“We generally don’t comment on pending citizens’ petitions,” an FDA spokesperson said in an email. “When we respond, we will respond directly to the petitioner and post the response in the designated agency public docket.”
 

Valisure’s Patent Application

Mr. Light and others have applied for a patent on methods of producing shelf-stable formulations to prevent degradation of BP to benzene.

“We saw the problem long before we had any sort of application,” Mr. Light said. The issue has been “known for decades.”
 

Role of BP Products for Acne

In the midst of uncertainty, “the first discussion is, do we want to use it?” Dr. Barbieri said in the interview. Some patients may want to avoid it altogether, until more data are available, including more verification of the findings, while others may be comfortable accepting the potential risk, he said.

“Benzoyl peroxide is one of our foundational acne treatments,” Dr. Barbieri said. In the American Academy of Dermatology updated guidelines on acne, published in January, 2024, strong recommendations were made for BP products, as well as topical retinoids, topical antibiotics, and oral doxycycline.

“When you take away BP, there’s no substitute for it,” Dr. Barbieri said. And if patients don’t get improvement with topicals, oral medications might be needed, and “these all have their own risks.”
 

 

 

In the Interim

Until more information is available, Dr. Barbieri is advising patients not to store the products at high temperatures or for a long time. Don’t keep the products past their expiration date, and perhaps keep products for a shorter time, “something like a month,” he said.

Those living in a hot climate might consider storing the products in the refrigerator, he said.

“We need more data from Valisure, from other groups that confirm their findings, and we need to hear from the FDA,” Dr. Barbieri said. “There’s a lot of uncertainty right now. But it’s important not to overreact.”

Dr. Barbieri had no relevant disclosures.

The Personal Care Products Council, a national trade association that represents cosmetic and personal care product manufacturers, also took issue with the findings and the approach used to evaluate the products.
 

FDA and the Citizen’s Petition

The FDA accepted the petition, Mr. Light said, and gave it a docket number. “We’ll hopefully hear more soon” because the FDA is required to respond to a citizen’s petition within 180 days, he said.

“We generally don’t comment on pending citizens’ petitions,” an FDA spokesperson said in an email. “When we respond, we will respond directly to the petitioner and post the response in the designated agency public docket.”
 

Valisure’s Patent Application

Mr. Light and others have applied for a patent on methods of producing shelf-stable formulations to prevent degradation of BP to benzene.

“We saw the problem long before we had any sort of application,” Mr. Light said. The issue has been “known for decades.”
 

Role of BP Products for Acne

In the midst of uncertainty, “the first discussion is, do we want to use it?” Dr. Barbieri said in the interview. Some patients may want to avoid it altogether, until more data are available, including more verification of the findings, while others may be comfortable accepting the potential risk, he said.

“Benzoyl peroxide is one of our foundational acne treatments,” Dr. Barbieri said. In the American Academy of Dermatology updated guidelines on acne, published in January, 2024, strong recommendations were made for BP products, as well as topical retinoids, topical antibiotics, and oral doxycycline.

“When you take away BP, there’s no substitute for it,” Dr. Barbieri said. And if patients don’t get improvement with topicals, oral medications might be needed, and “these all have their own risks.”
 

 

 

In the Interim

Until more information is available, Dr. Barbieri is advising patients not to store the products at high temperatures or for a long time. Don’t keep the products past their expiration date, and perhaps keep products for a shorter time, “something like a month,” he said.

Those living in a hot climate might consider storing the products in the refrigerator, he said.

“We need more data from Valisure, from other groups that confirm their findings, and we need to hear from the FDA,” Dr. Barbieri said. “There’s a lot of uncertainty right now. But it’s important not to overreact.”

Dr. Barbieri had no relevant disclosures.

AI in Clinical Dermatology: Consider Limitations, Current Issues

Article Type

Fri, 03/22/2024 - 13:07

SAN DIEGO — Just a day before the annual meeting of the American Academy of Dermatology (AAD) began, a study was published online in JAMA Dermatology, cautioning that most downloadable mobile apps driven by artificial intelligence (AI) for use in monitoring dermatologic conditions lack validation.

Not least of the problems among the 41 apps evaluated, the majority offered no supporting evidence, no information about whether the app performance had been validated, and no information about how user privacy would be managed, reported Shannon Wongvibulsin, MD, PhD, a resident in the dermatology program at the University of California, Los Angeles, and her coauthors.

The findings from this report were also summarized in a poster at the AAD meeting, and the major themes were reiterated in several AAD symposia devoted to AI at the meeting. Veronica Rotemberg, MD, PhD, a dermatologist at Memorial Sloan Kettering Cancer Center, New York City, was one of those who weighed in on the future of AI. Although she was the senior author of the report, she did not address the report or poster directly, but her presentation on the practical aspects of incorporating AI into dermatology practice revisited several of its themes. 

Of the different themes, perhaps the most important were the concept that the source of AI data matters and the point that practicing clinicians should be familiar with the data source.

To date, “there is not much transparency in what data AI models are using,” Dr. Rotemberg said at the meeting. Based on the expectation that dermatologists will be purchasing rather than developing their own AI-based systems, she reiterated more than once that “transparency of data is critical,” even if vendors are often reluctant to reveal how their proprietary systems have been developed.

Few Dermatology Apps Are Vetted for Accuracy

In the poster and in the more detailed JAMA Dermatology paper, Dr. Wongvibulsin and her coinvestigators evaluated direct-to-consumer downloadable apps that claim to help with the assessment and management of skin conditions. Very few provided any supporting evidence of accuracy or even information about how they functioned.

The 41 apps were drawn from more than 300 apps; the others were excluded for failing to meet such criteria as failing to employ AI, not being available in English, or not addressing clinical management of dermatologic diseases. Dr. Wongvibulsin pointed out that none of the apps had been granted regulatory approval even though only two provided a disclaimer to that effect.

In all, just 5 of the 41 provided supporting evidence from a peer-reviewed journal, and less than 40% were created with any input from a dermatologist, Dr. Wongvibulsin reported. The result is that the utility and accuracy of these apps were, for the most part, difficult to judge.

“At a minimum, app developers should provide details on what AI algorithms are used, what data sets were used for training, testing, and validation, whether there was any clinician input, whether there are any supporting publications, how user-submitted images are used, and if there are any measures used to ensure data privacy,” Dr. Wongvibulsin wrote in the poster.

For AI-based apps or systems designed for use by dermatologists, Dr. Rotemberg made similar assertions in her overview of what clinicians should be considering for proprietary AI systems, whether to help with diagnosis or improve office efficiency.
 

 

 

Only One Dermatology App Cleared By the FDA

Currently, the only FDA-cleared app for dermatologic use is the DermaSensor, an AI-driven device. It was cleared for use in January 2024 for the evaluation of skin lesions “suggestive” of melanomabasal cell carcinoma, and/or squamous cell carcinoma in patients aged ≥ 40 years “to assist health care providers in determining whether to refer a patient to a dermatologist,” according to an FDA announcement.

Using elastic scattering spectroscopy to analyze light reflecting off the skin to detect malignancy, the manufacturer’s promotional material claims a 96% sensitivity and a 97% specificity. 

While Dr. Rotemberg did not comment on these claims, she cautioned that AI models differ with regards to how they were trained and the relative heterogeneity of the training dataset defined by types of patients, types of skin, and types of AI learning processes. All of these variables are relevant in whether the AI will perform in a given clinical setting at the level it performed during development.

“The most accurate models employ narrow datasets, but these do not necessarily mimic what we see in practice,” she said.

In addition, even when an AI-based system is working for a given task, it must be monitored over time. Dr. Rotemberg warned about the potential for “data drift,” which describes the slow evolution in how diseases present, their prevalence by age, or other factors that might affect AI performance. She explained that repeated validation is needed to ensure that the AI-based models remain as accurate over time as they were when first used.

Many of these concepts were explored in a consensus statement from the International Skin Imaging Collaboration AI Working Group, published in JAMA Dermatology in December 2021. The statement, of which Dr. Rotemberg was a coauthor, provided recommendations for the principles of AI algorithm development specific to dermatologic considerations.

At the AAD symposium, Dr. Rotemberg asked the audience for suggestions about the needs they hoped AI might address for in office care or efficiency. Their responses included generating prior authorizations for prescriptions, triaging email for importance, and helping to improve efficiency for common front desk tasks. She liked all of these suggestions, but she warned that as powerful as it can be, AI is not likely to provide technology that will fit seamlessly into workflows without adjustment.

“Our current systems do not allow human integration of AI models,” Dr. Rotemberg said. Rather than counting on AI to adapt to current practices, she cautioned that “we may have to redesign our entire structure to actually be able to accommodate AI-based” systems. The risk for users is tasks that become more challenging before they become easier. 


AI Should Not Be a Black Box

AI is promising, but it is not magic, according to other investigators, including Tofunmi A. Omiye, PhD, a postdoctoral scholar in dermatology at Stanford University, California. First author of a recent review of AI in dermatology published in Frontiers in Medicine, Dr. Omiye agreed that clinicians who want to employ AI should be able to understand basic principles if they want the technology to perform as expected.

“I totally agree that physicians should at least have a basic understanding of the data sources for training AI models as we have found that to be important to the performance of these models in the clinical setting,” he told this news organization.

“Beyond understanding the data sources, I believe physicians can also try to have a comprehensive understanding of what AI means, its training process, and evaluation as this will help them to evaluate its utility in their practice,” he added. He also reinforced the relevance of data drift.

“Concepts like distribution shift — where models perform less well over time due to changes in the patient population — are also important to keep in mind,” Dr. Omiye said.

Dr. Wongvibulsin, Dr. Rotemberg, and Dr. Omiye reported no potential financial conflicts of interest relevant to this topic.

Nemolizumab Efficacy for Prurigo Nodularis Persists at 1 Year

Article Type
Changed
Fri, 03/22/2024 - 13:05

Nemolizumab, the first-in-class inhibitor of interleukin-31 (IL-31), a neuroimmune cytokine linked to the promotion of pruritus and inflammation, continues to show good efficacy and safety for prurigo nodularis in an open-label follow-up pivotal trial following patients out to 52 weeks.

The OLYMPIA 2 trial, published just a few months ago, was positive for the primary endpoint of itch, and the 52-week data show “on-going improvement” not just in this key symptom but in the resolution of skin lesions, according to Shawn Kwatra, MD, director of the itch center and associate professor of dermatology, Johns Hopkins School of Medicine, Baltimore, Maryland.

The drug, which was found well tolerated in the double-blind OLYMPIA 2 study at 16 weeks, has not been associated with any new adverse events (AEs) in follow-up so far, according to Dr. Kwatra, who presented these findings in a late-breaker session at the annual meeting of the American Academy of Dermatology (AAD).

The promise of an anti-IL-31 drug for sustained control of itch and inflammation was further supported by a separate late breaker on long-term maintenance data on nemolizumab for moderate to severe atopic dermatitis (AD).
 

New Prurigo Nodularis Therapies Needed

For prurigo nodularis, excitement about a new therapy is particularly warranted, according to Dr. Kwatra. Current treatment options, such as steroids and antihistamines, are neither well-tolerated nor particularly effective in most patients. He indicated that the very positive interim 52-week data from the ongoing open-label extension suggests that nemolizumab might be an important step forward for patients with this disease.

The interim 52-week analysis included 307 patients on continuous nemolizumab and 174 patients randomized previously to placebo and were nemolizumab-naive when they entered the open-label extension. Participants were drawn from the phase 3 trial as well as an earlier phase 2 study. Nemolizumab in all patients was delivered at a subcutaneous dose of 45 mg every 4 weeks.

Pointing out that the 2024 AAD annual meeting, with more than 19,000 attendees, “was the largest dermatology conference in the history of the world,” he added that his late-breaker results represent “the largest prurigo nodularis clinical study in the history of the world.”

At 52 weeks, 89.9% and 83.3% of those on continuous nemolizumab and those switched to nemolizumab, respectively, had achieved at least a 4-point reduction from baseline on the Peak Pruritus Numerical Rating Scale (NRS), which has a range from 0 to 10.

Approximately two thirds of patients (67.8% and 64.4%, respectively) had a weekly average peak NRS of ≤ 2, meaning they were free or almost free of itch. The improvement in a sleep index and in quality of life as measured with the Dermatology Life Quality Index closely followed the relief of itch with the large gains achieved within weeks of initiating treatment continuing on an upward slope at 52 weeks.

Over this time, lesions were also resolving. By week 52, healing of more than 75% of lesions had been achieved by 79.1% in both those on continuous nemolizumab and those who had been switched to nemolizumab. The rate of response was again about two thirds for those with lesion resolution considered clear or almost clear by the Investigator’s Global Assessment (IGA) response.
 

 

 

No Serious AEs Over Extended Follow-Up

With a mean duration of 388 days follow-up, there were no serious AEs that were clearly treatment related, but Dr. Kwatra did report that some patients developed mild eczematous lesions that typically responded to topical therapy. He also reported that asthma, particularly worsening asthma in patients already diagnosed with this disease, was seen in a small proportion of patients. Both were considered manageable, and no patients discontinued therapy because of these events, Dr. Kwatra said.

While further follow-up is planned, “we have never seen data in a prurigo nodularis [treatment trial] past 6 months,” he pointed out. For a challenging disease with a major adverse effect on quality of life, nemolizumab, if approved, will offer an important option for a difficult disease, he added.

Itch Improves in Patients with AD

Further support for the long-term safety of nemolizumab and its efficacy against itch was provided by another phase 3 extension study conducted in the treatment of AD. These long-term extension results were also presented in a late breaker session at the AAD meeting.

Evaluating maintenance data from responders, defined as a 75% reduction lesions on the Eczema Area and Severity Index (EASI-75) or as clear or almost clear skin on IGA at the end of the randomized ARCADIA 1 and 2 trials, there were 169 patients on every 4-week nemolizumab, 169 patients on every 8-week nemolizumab, and 169 patients on every 4-week placebo.

For pruritus, a ≥ 4 point NRS reduction was achieved at week 48 in 76.2% of those on the every 4-week dose, 59.7% of those on the every 8-week dose, and 41% on those on placebo, reported Jonathan Silverberg, MD, PhD, director of clinical research, Department of Dermatology, George Washington School of Medicine, Washington.

These not only represented sustained responses over the course of 48 weeks, but there was a gradual rise in this rate of success from baseline in the higher dose group. For a NRS score of ≤ 2, meaning no itch or almost no itch, the proportions were 64.9%, 52.9%, and 31.3%, respectively. These were accompanied by sustained responses in IGA and EASI-75 scores.

Overall, there was a “nice durability of response” over the maintenance period, with no new or dose-related safety signals, according to Dr. Silverberg. He pointed out that the every 8-week dose response was lower than every 4-week dose response, but “it looks very good” in regard to response and duration of response, “suggesting that this might be an option for a large subset of patients.”

Andrew Blauvelt, MD, an investigator with Oregon Medical Research Center, Portland, Oregon, cautioned that despite the promise, dermatologists “might need help” in understanding this new agent and using it appropriately. He pointed out that it employs a new mechanism of action, and it has “a couple of new twists that we have not seen with other drugs,” including its association with worsening asthma.

Noting that asthma exacerbation has been reported in a proportion of treated patients approaching 4%, he expressed concern “that this is not rare.” He also expressed concern about reports of peripheral edema and asked Dr. Kwatra specifically how this should be handled in the routine clinical setting.

Pointing out that the 1% of new cases of asthma in the nemolizumab arm was, in fact, lower than the rate of new cases in the placebo arm, Dr. Kwatra said that there have been cases of increased asthma symptoms in patients with existing disease. However, he added that this and the reports of peripheral edema, some of which appear to be simply associated with prurigo nodularis, typically resolve with routine interventions. He said, however, that these side effects represent legitimate concerns that clinicians should consider, but he indicated that they do not appear to be a threat to the benefit-to-risk ratio of this agent.

In February 2024, the Food and Drug Administration and the European Medicines Agency accepted submissions for nemolizumab for the treatment of prurigo nodularis and AD, according to Galderma, the company developing nemolizumab.

Dr. Kwatra reported a financial relationship with more than 15 pharmaceutical companies, including Galderma, which sponsored the nemolizumab trials. Dr. Silverberg reported financial relationships with more than 35 pharmaceutical companies, including Galderma. Dr. Blauvelt reported financial relationships with more than 20 pharmaceutical companies, including Galderma.

The interim 52-week analysis included 307 patients on continuous nemolizumab and 174 patients randomized previously to placebo and were nemolizumab-naive when they entered the open-label extension. Participants were drawn from the phase 3 trial as well as an earlier phase 2 study. Nemolizumab in all patients was delivered at a subcutaneous dose of 45 mg every 4 weeks.

Pointing out that the 2024 AAD annual meeting, with more than 19,000 attendees, “was the largest dermatology conference in the history of the world,” he added that his late-breaker results represent “the largest prurigo nodularis clinical study in the history of the world.”

At 52 weeks, 89.9% and 83.3% of those on continuous nemolizumab and those switched to nemolizumab, respectively, had achieved at least a 4-point reduction from baseline on the Peak Pruritus Numerical Rating Scale (NRS), which has a range from 0 to 10.

Approximately two thirds of patients (67.8% and 64.4%, respectively) had a weekly average peak NRS of ≤ 2, meaning they were free or almost free of itch. The improvement in a sleep index and in quality of life as measured with the Dermatology Life Quality Index closely followed the relief of itch with the large gains achieved within weeks of initiating treatment continuing on an upward slope at 52 weeks.

Over this time, lesions were also resolving. By week 52, healing of more than 75% of lesions had been achieved by 79.1% in both those on continuous nemolizumab and those who had been switched to nemolizumab. The rate of response was again about two thirds for those with lesion resolution considered clear or almost clear by the Investigator’s Global Assessment (IGA) response.
 

 

 

No Serious AEs Over Extended Follow-Up

With a mean duration of 388 days follow-up, there were no serious AEs that were clearly treatment related, but Dr. Kwatra did report that some patients developed mild eczematous lesions that typically responded to topical therapy. He also reported that asthma, particularly worsening asthma in patients already diagnosed with this disease, was seen in a small proportion of patients. Both were considered manageable, and no patients discontinued therapy because of these events, Dr. Kwatra said.

While further follow-up is planned, “we have never seen data in a prurigo nodularis [treatment trial] past 6 months,” he pointed out. For a challenging disease with a major adverse effect on quality of life, nemolizumab, if approved, will offer an important option for a difficult disease, he added.

Itch Improves in Patients with AD

Further support for the long-term safety of nemolizumab and its efficacy against itch was provided by another phase 3 extension study conducted in the treatment of AD. These long-term extension results were also presented in a late breaker session at the AAD meeting.

Evaluating maintenance data from responders, defined as a 75% reduction lesions on the Eczema Area and Severity Index (EASI-75) or as clear or almost clear skin on IGA at the end of the randomized ARCADIA 1 and 2 trials, there were 169 patients on every 4-week nemolizumab, 169 patients on every 8-week nemolizumab, and 169 patients on every 4-week placebo.

For pruritus, a ≥ 4 point NRS reduction was achieved at week 48 in 76.2% of those on the every 4-week dose, 59.7% of those on the every 8-week dose, and 41% on those on placebo, reported Jonathan Silverberg, MD, PhD, director of clinical research, Department of Dermatology, George Washington School of Medicine, Washington.

These not only represented sustained responses over the course of 48 weeks, but there was a gradual rise in this rate of success from baseline in the higher dose group. For a NRS score of ≤ 2, meaning no itch or almost no itch, the proportions were 64.9%, 52.9%, and 31.3%, respectively. These were accompanied by sustained responses in IGA and EASI-75 scores.

Overall, there was a “nice durability of response” over the maintenance period, with no new or dose-related safety signals, according to Dr. Silverberg. He pointed out that the every 8-week dose response was lower than every 4-week dose response, but “it looks very good” in regard to response and duration of response, “suggesting that this might be an option for a large subset of patients.”

Andrew Blauvelt, MD, an investigator with Oregon Medical Research Center, Portland, Oregon, cautioned that despite the promise, dermatologists “might need help” in understanding this new agent and using it appropriately. He pointed out that it employs a new mechanism of action, and it has “a couple of new twists that we have not seen with other drugs,” including its association with worsening asthma.

Noting that asthma exacerbation has been reported in a proportion of treated patients approaching 4%, he expressed concern “that this is not rare.” He also expressed concern about reports of peripheral edema and asked Dr. Kwatra specifically how this should be handled in the routine clinical setting.

Pointing out that the 1% of new cases of asthma in the nemolizumab arm was, in fact, lower than the rate of new cases in the placebo arm, Dr. Kwatra said that there have been cases of increased asthma symptoms in patients with existing disease. However, he added that this and the reports of peripheral edema, some of which appear to be simply associated with prurigo nodularis, typically resolve with routine interventions. He said, however, that these side effects represent legitimate concerns that clinicians should consider, but he indicated that they do not appear to be a threat to the benefit-to-risk ratio of this agent.

In February 2024, the Food and Drug Administration and the European Medicines Agency accepted submissions for nemolizumab for the treatment of prurigo nodularis and AD, according to Galderma, the company developing nemolizumab.

Dr. Kwatra reported a financial relationship with more than 15 pharmaceutical companies, including Galderma, which sponsored the nemolizumab trials. Dr. Silverberg reported financial relationships with more than 35 pharmaceutical companies, including Galderma. Dr. Blauvelt reported financial relationships with more than 20 pharmaceutical companies, including Galderma.

Nemolizumab, the first-in-class inhibitor of interleukin-31 (IL-31), a neuroimmune cytokine linked to the promotion of pruritus and inflammation, continues to show good efficacy and safety for prurigo nodularis in an open-label follow-up pivotal trial following patients out to 52 weeks.

The OLYMPIA 2 trial, published just a few months ago, was positive for the primary endpoint of itch, and the 52-week data show “on-going improvement” not just in this key symptom but in the resolution of skin lesions, according to Shawn Kwatra, MD, director of the itch center and associate professor of dermatology, Johns Hopkins School of Medicine, Baltimore, Maryland.

The drug, which was found well tolerated in the double-blind OLYMPIA 2 study at 16 weeks, has not been associated with any new adverse events (AEs) in follow-up so far, according to Dr. Kwatra, who presented these findings in a late-breaker session at the annual meeting of the American Academy of Dermatology (AAD).

The promise of an anti-IL-31 drug for sustained control of itch and inflammation was further supported by a separate late breaker on long-term maintenance data on nemolizumab for moderate to severe atopic dermatitis (AD).
 

New Prurigo Nodularis Therapies Needed

For prurigo nodularis, excitement about a new therapy is particularly warranted, according to Dr. Kwatra. Current treatment options, such as steroids and antihistamines, are neither well-tolerated nor particularly effective in most patients. He indicated that the very positive interim 52-week data from the ongoing open-label extension suggests that nemolizumab might be an important step forward for patients with this disease.

Approval of Spesolimab for Generalized Pustular Psoriasis Expanded

Article Type
Changed
Fri, 03/22/2024 - 10:06

The Food and Drug Administration (FDA) has approved spesolimab-sbzo, an interleukin (IL)-36 receptor antagonist, for the treatment of generalized pustular psoriasis (GPP) in adults and in pediatric patients aged ≥ 12 years who weigh ≥ 40 kg, according to an announcement from the manufacturer. 

This is an expanded indication for spesolimab-sbzo, first approved in September 2022 for treating GPP flares. Developed by Boehringer Ingelheim and marketed under the name Spevigo, the product is an injectable antibody that blocks the IL-36 receptor, a key part of the pathway shown to be involved in the cause of GPP, which is rare and is a potentially-life-threatening disease.



According to a press release from the company, the FDA’s approval of the expanded indication was based on the results of a 48-week clinical trial of 123 patients (Effisayil 2), which showed that individuals who received spesolimab experienced a significant 84% reduction in GPP flares compared with those who received placebo. Among 30 study participants who received a high treatment dose, no flares were observed after week 4. Among all patients who received spesolimab-sbzo, treatment was associated with an increased incidence (defined as ≥ 9 cases per 100 patient-years) of injection site reactions, urinary tract infections, arthralgia, and pruritus compared with placebo. 

Spesolimab-sbzo is currently available in 48 countries, according to the Boehringer Ingelheim release, which states that the approval makes it the first targeted therapy that is available for the acute and chronic treatment of patients with GPP.

Lebrikizumab Found Effective for Atopic Dermatitis in Patients With Darker Skin Tones

Article Type
Changed
Thu, 03/21/2024 - 15:35

Among patients with skin of color and moderate to severe atopic dermatitis (AD) who underwent 16 weeks of treatment with lebrikizumab, 68% achieved a 75% reduction in the Eczema Area and Severity Index (EASI-75), interim results from a novel phase 3b trial showed.

Lebrikizumab, a novel monoclonal antibody being developed by Eli Lilly and Co, binds with high affinity to interleukin (IL)–13, thereby blocking the downstream effects of IL-13 with high potency, one of the study investigators, Jill S. Waibel, MD, a dermatologist in Miami, said at the annual meeting of the American Academy of Dermatology. Though the efficacy and safety of lebrikizumab to treat moderate to severe AD have been established in phase 3 studies, including subset analyses by race and ethnicity, “there is a paucity of data to guide the treatment of moderate-to-severe AD in populations traditionally under-represented in clinical trials, including patients with skin of color,” she said.

During a late-breaking abstract session, Dr. Waibel presented interim 16-week results from ADmirable, a phase 3b, open-label, 24-week study, was the first study to evaluate the safety and efficacy of lebrikizumab in adult and adolescents with skin of color and moderate to severe AD. At baseline and at 2 weeks, patients received a 500-mg loading dose of lebrikizumab. Through week 16, they received a 250-mg dose every 2 weeks. The study’s primary endpoint was the proportion of patients who achieved a 75% reduction in EASI-75 at week 16. “If they achieved the primary endpoint at week 16, they went to a 250-mg dose every 4 weeks,” Dr. Waibel said. “If they did not achieve that [primary endpoint] they stayed on the 250-mg dose every 2 weeks.”

The analysis included 50 patients with skin types IV, V, and VI who self-reported their race as Black or African American, American Indian or Alaska Native, Asian, and Native Hawaiian or Other Pacific Islander. They had chronic AD for at least 1 year, moderate to severe disease at baseline, a history of an inadequate response to topical medications, and were naive to biologics indicated for the treatment of AD.

Week 16 outcomes of interest were the EASI, the Investigator’s Global Assessment (IGA) of 0 or 1, the Pruritus Numerical Rating Scale (NRS), and PDCA-Derm, a scale developed by Eli Lilly and Co that was used to compare postinflammatory lesions to unaffected adjacent normal skin. All data for statistical analyses were summarized as observed.

At baseline, the mean age of the 50 patients was 42 years, 46% were women, their mean body mass index was 30.2, and the mean age at AD onset was 23 years. Most study participants (80%) were Black or African American, 14% were Asian, and 6% were American Indian or Alaska Native; 78% were not Hispanic or Latino and 22% were Hispanic or Latino. The mean EASI score was 28.1, the mean body surface area affected was 41.7%, and the mean Pruritus NRS score was 7.2 out of 11. According to the PDCA-Derm scale, 18% of patients had hypopigmented lesions, and 54% had hyperpigmented lesions.



After 16 weeks of treatment, 68% of patients achieved an EASI-75 response, whereas 46% achieved an EASI-90 response, Dr. Waibel reported at the meeting. In addition, 39% of patients achieved an IGA score of 0 or 1, 56% achieved a ≥ 4-point improvement on the Pruritus NRS, and 66% achieved a ≥ 3-point improvement on the Pruritus NRS. The PDCA-Derm score identified improvement in postinflammatory hyperpigmented lesions in 12 of 21 patients and improvement to normal skin tone in six of 21 patients.

“I have a large population [with skin of color in my practice],” Dr. Waibel said. “I usually tell my [patients with postinflammatory hyperpigmentation] that it takes 6 months to see improvement. In this study, we saw patients achieve improvement in skin tone in a 4-month time frame. PIH is sometimes more distressing than a primary condition, whether it’s acne or atopic dermatitis. In this case, it was surprisingly improved with lebrikizumab.”

No new safety signals or serious adverse events were observed. “This is very exciting because it’s the first time there has been a trial focusing on [patients with skin of color] with moderate to severe eczema in skin types IV-VI,” Dr. Waibel said.

In an interview, the study’s lead investigator, Andrew Alexis, MD, MPH, vice chair for diversity and inclusion in the department of dermatology and professor of clinical dermatology at Weill Cornell Medicine, New York City, said that the interim results from this study “ add valuable, clinically relevant data on the treatment of moderate to severe AD in patient populations with skin of color.”

Dr. Andrew F. Alexis

“An interesting finding,” he continued, “was that improvement in postinflammatory hyperpigmented lesions was seen in 12 of 21 patients and improvement to normal skin tone was observed in six of 21 patients at week 16. This is particularly relevant to patients with skin of color who frequently suffer from pigmentary changes in association with their AD.”

Lebrikizumab was approved in November 2023 in Europe for the treatment of moderate to severe AD in people aged 12 years or older and is currently under review by the Food and Drug Administration for treatment of AD. 

Both Dr. Waibel and Dr. Alexis disclosed numerous conflicts of interest from various pharmaceutical companies, including serving as a consultant and/or advisor to Eli Lilly and Co.

At baseline and at 2 weeks, patients received a 500-mg loading dose of lebrikizumab. Through week 16, they received a 250-mg dose every 2 weeks. The study’s primary endpoint was the proportion of patients who achieved a 75% reduction in EASI-75 at week 16. “If they achieved the primary endpoint at week 16, they went to a 250-mg dose every 4 weeks,” Dr. Waibel said. “If they did not achieve that [primary endpoint] they stayed on the 250-mg dose every 2 weeks.”

The analysis included 50 patients with skin types IV, V, and VI who self-reported their race as Black or African American, American Indian or Alaska Native, Asian, and Native Hawaiian or Other Pacific Islander. They had chronic AD for at least 1 year, moderate to severe disease at baseline, a history of an inadequate response to topical medications, and were naive to biologics indicated for the treatment of AD.

Week 16 outcomes of interest were the EASI, the Investigator’s Global Assessment (IGA) of 0 or 1, the Pruritus Numerical Rating Scale (NRS), and PDCA-Derm, a scale developed by Eli Lilly and Co that was used to compare postinflammatory lesions to unaffected adjacent normal skin. All data for statistical analyses were summarized as observed.

At baseline, the mean age of the 50 patients was 42 years, 46% were women, their mean body mass index was 30.2, and the mean age at AD onset was 23 years. Most study participants (80%) were Black or African American, 14% were Asian, and 6% were American Indian or Alaska Native; 78% were not Hispanic or Latino and 22% were Hispanic or Latino. The mean EASI score was 28.1, the mean body surface area affected was 41.7%, and the mean Pruritus NRS score was 7.2 out of 11. According to the PDCA-Derm scale, 18% of patients had hypopigmented lesions, and 54% had hyperpigmented lesions.



After 16 weeks of treatment, 68% of patients achieved an EASI-75 response, whereas 46% achieved an EASI-90 response, Dr. Waibel reported at the meeting. In addition, 39% of patients achieved an IGA score of 0 or 1, 56% achieved a ≥ 4-point improvement on the Pruritus NRS, and 66% achieved a ≥ 3-point improvement on the Pruritus NRS. The PDCA-Derm score identified improvement in postinflammatory hyperpigmented lesions in 12 of 21 patients and improvement to normal skin tone in six of 21 patients.

“I have a large population [with skin of color in my practice],” Dr. Waibel said. “I usually tell my [patients with postinflammatory hyperpigmentation] that it takes 6 months to see improvement. In this study, we saw patients achieve improvement in skin tone in a 4-month time frame. PIH is sometimes more distressing than a primary condition, whether it’s acne or atopic dermatitis. In this case, it was surprisingly improved with lebrikizumab.”

No new safety signals or serious adverse events were observed. “This is very exciting because it’s the first time there has been a trial focusing on [patients with skin of color] with moderate to severe eczema in skin types IV-VI,” Dr. Waibel said.

In an interview, the study’s lead investigator, Andrew Alexis, MD, MPH, vice chair for diversity and inclusion in the department of dermatology and professor of clinical dermatology at Weill Cornell Medicine, New York City, said that the interim results from this study “ add valuable, clinically relevant data on the treatment of moderate to severe AD in patient populations with skin of color.”

Dr. Andrew F. Alexis

“An interesting finding,” he continued, “was that improvement in postinflammatory hyperpigmented lesions was seen in 12 of 21 patients and improvement to normal skin tone was observed in six of 21 patients at week 16. This is particularly relevant to patients with skin of color who frequently suffer from pigmentary changes in association with their AD.”

Lebrikizumab was approved in November 2023 in Europe for the treatment of moderate to severe AD in people aged 12 years or older and is currently under review by the Food and Drug Administration for treatment of AD. 

Both Dr. Waibel and Dr. Alexis disclosed numerous conflicts of interest from various pharmaceutical companies, including serving as a consultant and/or advisor to Eli Lilly and Co.

LITE Study Provides Encouraging Data on Home-Based Phototherapy for Psoriasis

Article Type

Fri, 03/22/2024 - 10:10

Home-based phototherapy is non-inferior to office-based phototherapy for the treatment of plaque and guttate psoriasis across all skin types and was associated with improved Physician’s Global Assessment (PGA) and Dermatology Life Quality Index (DLQI) scores, results from a pragmatic, multicenter study showed.

“In 2024, we have a lot of ways to treat moderate-to-severe psoriasis, and phototherapy remains relevant,” lead investigator Joel M. Gelfand, MD, professor of dermatology and epidemiology at the University of Pennsylvania in Philadelphia, told attendees of a late-breaking abstract session at the annual meeting of the American Academy of Dermatology.

“Office phototherapy is 10 to 100 times less expensive than biologics for psoriasis, and in head-to-head trials, it’s about as effective as adalimumab and achieves better patient-reported outcomes. It may have some cardiovascular benefits by lowering IL-6 and improving HDL-P,” he said. “And, compared to secukinumab, it has no risk of infection.”

Although phototherapy is a preferred as a treatment by patients with psoriasis, he continued, inconvenience of traveling to a clinician’s office for the treatment and lack of coverage by health insurance plans remain major barriers to this option. According to Dr. Gelfand, office-based phototherapy is not available in 90% of counties in the United States, “and a lack of US data has resulted in many insurance companies not covering home phototherapy. As a result, many providers are uncertain about prescribing it.”
 

LITE Study Data

In 2019, Dr. Gelfand and colleagues Light Treatment Effectiveness (LITE) study, a patient-centered study that tested the hypothesis that narrowband UVB phototherapy of psoriasis at home is non-inferior to office treatment, based on outcomes that matter to patients, clinicians, and payers. The co-primary outcomes were a PGA score of 0/1 (clear, almost clear) and a DLQI score of 5 or less (small, no effect on health-related quality of life).

Dr. Gelfand and colleagues at 42 sites in the United States enrolled 783 patients aged 12 years and older who had plaque or guttate psoriasis and were candidates for phototherapy at home or in an office setting. New or established patients to the practices were accepted into the trial, while those treated with phototherapy within 14 days before the baseline visit were not. These entry criteria “are highly pragmatic and reflect routine clinical practice,” he said.

The researchers evenly stratified patients by skin types I and II, III and IV, and V and VI. They collected data from medical records or from an app on the patient’s cell phone, which captured the DLQI data. Study participants were randomly assigned 1:1 to office- or home-based phototherapy for 12 weeks at doses recommended in the 2019 AAD-National Psoriasis Foundation guidelines. This was followed by a 12-week observation period, which ended at 24 weeks. 

At baseline, the mean DLQI score of patients was 12.2, the mean PGA score was 3, and their mean body surface area affected was 12.5%. “These patients had pretty severe disease, long-standing disease, and about 12% were on biologics or nonbiologic systemic therapy during the study,” said Dr. Gelfand, also the director of the Psoriasis and Phototherapy Treatment Center at Penn. In addition, he said, “the average round-trip to receive phototherapy in the office was about 60 minutes.”
 

 

 

An Improvement in Health Equity

Following treatment at 12 weeks, 25.6% of patients in the office-based phototherapy group achieved a PGA of 0/1, compared with 32.8% of patients in the home-based phototherapy group (P >.0001 for non-inferiority). Similarly, 33.6% of patients in the office-based phototherapy group achieved a score of 5 or less on the DLQI, compared with 52.4% of patients in the home-based phototherapy group (P >.0001 for non-inferiority).

In subgroup analyses, patients with darkly pigmented skin did especially well on home phototherapy relative to office treatment. “This finding is an example of how the LITE study was specifically designed to improve health equity through an intentionally inclusive approach,” Dr. Gelfand said. Perhaps not surprisingly, patients in the home-based phototherapy arm were more adherent to treatment compared with those in the office-based arm (a mean of 26.8 sessions during the study period, compared with a mean of 17.9, respectively; P < .0001). “They also had higher cumulative doses of phototherapy and therefore higher episodes of treatments with erythema,” he noted.

Among patients who reported “itchy, sore, painful, or stinging” skin in the previous week, 63% characterized the degree of discomfort as “not at all or a little,” while 28% said “a lot,” and 9% said “very much.” No patients withdrew or stopped phototherapy during the trial because of treatment-related side effects, “so it’s very well tolerated,” Dr. Gelfand said.



“If a patient never had phototherapy before, they did just as well at home as they did in the office. This suggests that there’s no reason to insist that a patient use office-based phototherapy before using home phototherapy.”

The researchers studied the efficacy of narrow-band UVB in patients who had at least two treatments per week for 12 weeks. In this subgroup of patients, 60% achieved clear or almost clear skin and nearly 50% achieved the equivalent of a Psoriasis Area and Severity Index (PASI) 90 score.

“Home phototherapy is clearly non-inferior to office-based phototherapy across all skin types and both primary outcomes, PGA and DLQI, and both have excellent effectiveness and safety in real-world settings,” Dr. Gelfand concluded. “These data support the use of home phototherapy as a first-line treatment option for psoriasis, including those with no prior phototherapy experience.”

LITE Study Described as “Groundbreaking”

One of the session moderators, dermatologist Andrew Blauvelt, MD, MBA, of the Oregon Medical Research Center, Portland, asked about the impact that lockdowns during the early phase of the COVID-19 pandemic had on the trial. “The study shut down for a couple weeks during the initial lockdown, but we got back up and running pretty quickly,” Dr. Gelfand responded. “We didn’t study that specific period of time, but the study was going on well before COVID and well after COVID restrictions were lifted. We’ll have to analyze that period of time you question but I suspect that it’s not driving the results we see.”

Asked to comment, Henry W. Lim, MD, a dermatologist with Henry Ford Health in Detroit, characterized the findings of the study as “groundbreaking, because it looked at a real-life situation in the use of phototherapy at home vs in the office, showing that the home phototherapy is not inferior to office-based phototherapy.”

Dr. Henry W. Lim


This is important, he continued, “because it can inform payers to approve home phototherapy equipment for patients, because it’s much more convenient and it definitely works. The other strong point of the study is that it included patients of different skin types,” he said in an interview at the meeting.

The study was funded by the Patient-Centered Outcomes Research Institute. Research partners included the National Psoriasis Foundation and Daavlin, which provided the home phototherapy machines and covered the cost of shipping the devices. Dr. Gelfand reported no relevant financial relationships. Dr. Blauvelt disclosed conflicts of interest from many pharmaceutical companies. Dr. Lim disclosed conflicts of interest from many pharmaceutical companies.

BTK Inhibitor Shows Promise for Hidradenitis Suppurativa

Article Type
Changed
Thu, 03/21/2024 - 13:03

The investigative oral Bruton’s tyrosine kinase (BTK) inhibitor remibrutinib shows promise in patients with moderate to severe hidradenitis suppurativa (HS), results from a randomized 16-week phase 2 trial showed.

“Research shows that the TNF-alpha and IL-17 signaling pathways have important roles in HS,” lead investigator Alexa B. Kimball, MD, MPH, from the Clinical Laboratory for Epidemiology and Applied Research in Skin at Beth Israel Deaconess Medical Center, Boston, said at the annual meeting of the American Academy of Dermatology. “However, several additional pathways are thought to contribute to disease pathogenesis.”

Dr. Alexa B. Kimball


The presence of B cells and plasma cells has been reported in HS lesions, she continued, including early lesions, with BTK activation as a central signal transduction pathway. For the current study, Dr. Kimball and colleagues evaluated the safety and efficacy of remibrutinib (LOU064), an oral, highly selective BTK inhibitor, in 77 adults with moderate to severe HS for at least 12 months in 2 or more anatomical areas with 15 or fewer tunnels beneath the skin.

There were slightly more women than men and more than 90% of study participants were White. The novel drug, which is being developed by Novartis, is also under investigation in other immune-mediated inflammatory diseases, including chronic spontaneous urticaria and multiple sclerosis.

Of the 77 patients, 33 were assigned to receive 100 mg remibrutinib twice per day, 33 received a 25 mg twice-daily dose, and 11 patients received placebo twice per day. The primary endpoint was the proportion of patients who achieved a simplified Hidradenitis Suppurativa Clinical Response (HiSCR) at week 16 compared with pooled placebo. A simplified HiSCR response was defined as at least a 50% reduction in total inflammatory abscess and nodule (AN) count, with no increase in draining tunnels relative to baseline.

Dr. Kimball, professor of dermatology at Harvard University, reported that 80.2% of patients overall completed treatment: 87.9% and 78.8% in the remibrutinib 25 mg and 100 mg arms, respectively, and 76% in the pooled placebo arm. The main reason for treatment discontinuation was patient decision (60.9%). Nearly three quarters of patients in the remibrutinib 25 mg twice-daily arm (72.7%) achieved the simplified HiSCR endpoint, compared with 48.5% of those in the remibrutinib 100 mg twice-daily arm, and 34.7% of those in the placebo arm. 

In other exploratory findings, HiSCR, HiSCR 75, and HiSCR 90 rates were higher at week 16 among patients in both remibrutinib treatment arms compared with placebo, and the study drug also was associated with a greater effect on reduction of the AN count and draining tunnels. Specifically, the estimated mean percentage reduction in AN count was 68% in the 25 mg twice-daily arm, compared with reductions of 57% in the 100 mg twice-daily arm and 49.7% in the placebo arm, respectively. Meanwhile, the estimated mean reductions in draining tunnels were 55.6%, 43.6%, and 10.2%, respectively, in the three arms.

The researchers also observed a greater response on the Patient’s Global Assessment of Skin Pain Numeric Rating Scale 30 (NRS30) in patients treated with remibrutinib compared with those on placebo at week 16 (57.1% in the 100 mg twice-daily arm, compared with 44.4% in the 25 mg twice-daily arm, and 30.4% in the placebo arm). 

In terms of safety, adverse events (AEs) were mainly mild or moderate in severity, Dr. Kimball said, with no deaths and only one serious AE reported in each treatment arm: one case of acute pancreatitis in the 25 mg twice-daily arm, a testicular abscess in the pooled placebo arm, and a hypertensive crisis in the 100 mg twice-daily arm. Treatment discontinuations because of AEs were uncommon. Infections (primarily upper respiratory infections such as nasopharyngitis) were the most common AEs in all treatment arms.

“BTK inhibition may emerge as a promising therapeutic option in HS,” Dr. Kimball concluded. “This is wonderful news for our HS community. We are looking forward to determining what the optimal dosing will be going forward.”

Jennifer L. Hsiao, MD, associate professor of dermatology and director of the HS clinic at the University of Southern California, Los Angeles, who was asked to comment on the study, said there is “a pressing need for more treatments for patients with HS who suffer from the pain and oftentimes life-limiting nature of this condition.” She characterized the study results as “promising.”

The investigative oral Bruton’s tyrosine kinase (BTK) inhibitor remibrutinib shows promise in patients with moderate to severe hidradenitis suppurativa (HS), results from a randomized 16-week phase 2 trial showed.

“Research shows that the TNF-alpha and IL-17 signaling pathways have important roles in HS,” lead investigator Alexa B. Kimball, MD, MPH, from the Clinical Laboratory for Epidemiology and Applied Research in Skin at Beth Israel Deaconess Medical Center, Boston, said at the annual meeting of the American Academy of Dermatology. “However, several additional pathways are thought to contribute to disease pathogenesis.”

Dr. Alexa B. Kimball


The presence of B cells and plasma cells has been reported in HS lesions, she continued, including early lesions, with BTK activation as a central signal transduction pathway. For the current study, Dr. Kimball and colleagues evaluated the safety and efficacy of remibrutinib (LOU064), an oral, highly selective BTK inhibitor, in 77 adults with moderate to severe HS for at least 12 months in 2 or more anatomical areas with 15 or fewer tunnels beneath the skin.

There were slightly more women than men and more than 90% of study participants were White. The novel drug, which is being developed by Novartis, is also under investigation in other immune-mediated inflammatory diseases, including chronic spontaneous urticaria and multiple sclerosis.

Of the 77 patients, 33 were assigned to receive 100 mg remibrutinib twice per day, 33 received a 25 mg twice-daily dose, and 11 patients received placebo twice per day. The primary endpoint was the proportion of patients who achieved a simplified Hidradenitis Suppurativa Clinical Response (HiSCR) at week 16 compared with pooled placebo. A simplified HiSCR response was defined as at least a 50% reduction in total inflammatory abscess and nodule (AN) count, with no increase in draining tunnels relative to baseline.

Dr. Kimball, professor of dermatology at Harvard University, reported that 80.2% of patients overall completed treatment: 87.9% and 78.8% in the remibrutinib 25 mg and 100 mg arms, respectively, and 76% in the pooled placebo arm. The main reason for treatment discontinuation was patient decision (60.9%). Nearly three quarters of patients in the remibrutinib 25 mg twice-daily arm (72.7%) achieved the simplified HiSCR endpoint, compared with 48.5% of those in the remibrutinib 100 mg twice-daily arm, and 34.7% of those in the placebo arm. 

In other exploratory findings, HiSCR, HiSCR 75, and HiSCR 90 rates were higher at week 16 among patients in both remibrutinib treatment arms compared with placebo, and the study drug also was associated with a greater effect on reduction of the AN count and draining tunnels. Specifically, the estimated mean percentage reduction in AN count was 68% in the 25 mg twice-daily arm, compared with reductions of 57% in the 100 mg twice-daily arm and 49.7% in the placebo arm, respectively. Meanwhile, the estimated mean reductions in draining tunnels were 55.6%, 43.6%, and 10.2%, respectively, in the three arms.

The researchers also observed a greater response on the Patient’s Global Assessment of Skin Pain Numeric Rating Scale 30 (NRS30) in patients treated with remibrutinib compared with those on placebo at week 16 (57.1% in the 100 mg twice-daily arm, compared with 44.4% in the 25 mg twice-daily arm, and 30.4% in the placebo arm). 

In terms of safety, adverse events (AEs) were mainly mild or moderate in severity, Dr. Kimball said, with no deaths and only one serious AE reported in each treatment arm: one case of acute pancreatitis in the 25 mg twice-daily arm, a testicular abscess in the pooled placebo arm, and a hypertensive crisis in the 100 mg twice-daily arm. Treatment discontinuations because of AEs were uncommon. Infections (primarily upper respiratory infections such as nasopharyngitis) were the most common AEs in all treatment arms.

“BTK inhibition may emerge as a promising therapeutic option in HS,” Dr. Kimball concluded. “This is wonderful news for our HS community. We are looking forward to determining what the optimal dosing will be going forward.”

Jennifer L. Hsiao, MD, associate professor of dermatology and director of the HS clinic at the University of Southern California, Los Angeles, who was asked to comment on the study, said there is “a pressing need for more treatments for patients with HS who suffer from the pain and oftentimes life-limiting nature of this condition.” She characterized the study results as “promising.”

Study Links Maternal Hidradenitis Suppurativa to Risk for Childhood Morbidity

Article Type

Thu, 03/21/2024 - 11:04

Maternal hidradenitis suppurativa (HS) is associated with an increased risk for adverse birth outcomes and childhood morbidities, including respiratory, metabolic, central nervous system, and other conditions.

Those are key findings from a longitudinal cohort study that was presented during a poster session at the annual meeting of the American Academy of Dermatology.

“HS is associated with morbidity in women of reproductive age and adverse pregnancy outcomes, [but] its effect on offspring outcomes remains unclear,” corresponding author Kaiyang Li, a third-year medical student at McGill University, Quebec, Canada, and coauthors wrote in their abstract.

To investigate the association between maternal HS and offspring outcomes at birth and with up to 16 years of follow-up, the researchers drew from a longitudinal cohort of 1,275,593 children born in Quebec between April 1, 2006 and March 31, 2022. They matched children with their mothers and used identification numbers to follow the children to note morbidities that led to hospital admissions before age 16 years. The exposure of interest was HS, and the main outcome measure was childhood hospitalizations for respiratory, cardiovascular, metabolic, and other morbidities prior to age 16 years. 

Next, they estimated hazard ratios (HR) and 95% CIs for the association of maternal HS with childhood morbidity in adjusted Cox proportional hazards regression models. “As prenatal exposure to hyperandrogenism may influence boys and girls differently, we carried out subgroup analyses stratified by child sex,” they wrote. 



The study population included 1283 children whose mothers had HS and 1,274,310 unexposed children. As for infant outcomes, compared with no exposure, maternal HS was associated with an increased risk for preterm birth (relative risk [RR], 1.29; 95% CI, 1,08-1.55), neonatal death (RR, 2.07; 95% CI, 1.03-14.13), birth defects (RR, 1.29; 95% CI, 1.07-1.56), congenital heart defects (RR, 1.57; 95% CI, 1.02-2.44), and orofacial defects (RR 4.29; 95% CI, 1.85-9.97).

As for long-term outcomes in the children, compared with those whose mothers did not have HS, maternal HS was associated with an increased risk for any childhood hospitalization (HR, 1.31; 95% CI, 1.19-1.44), respiratory hospitalization (HR, 1.21; 95% CI, 1.05-1.40), metabolic hospitalization (HR, 2.64; 95% CI, 1.67-4.20), gastrointestinal hospitalization (HR, 1.34; 95% CI, 1.03-1.74), and developmental hospitalization (HR, 1.92; 95% CI, 1.43-2.58).

Commenting on the results after the meeting, Ms. Li said that the findings support the need for timely management of HS in expectant mothers and people planning to conceive, and for “interdisciplinary care and follow up for both the mother and the baby, involving the dermatologist, the obstetrician, and the neonatologist or pediatrician if needed.”

“HS is a multidisciplinary disease, plain and simple,” Adam Friedman, MD, professor and chair of dermatology, George Washington University, Washington, who was asked to comment on the study, said in an interview. “This study highlights the importance of collaboration between dermatology and obstetrician-gynecologist given the potential negative pregnancy outcomes, but to me raising alarm bells given the known gaps and delays in diagnosis matched to disease onset,” said Dr. Friedman, who was not involved with the study. “We need to do better to ensure the safety of both patient and patient-to-be.”

The researchers reported having no financial disclosures. The abstract was selected as the second-place winner in the AAD’s poster competition. Dr. Friedman has no relevant disclosures.

Acne Risk With Progestin-Only Long-Acting Reversible Contraceptives Evaluated

Article Type
Changed
Thu, 03/21/2024 - 10:40

 

TOPLINE: 

Despite the risk of worsening acne with progestin-only long-acting reversible contraception (LARC) in a study of adolescents and young adults, acne alone was not a common reason for discontinuation.

METHODOLOGY:

  • Progestin-only LARC may increase the risk for acne, but this has not been well studied in adolescents and young adults.
  • In the study, researchers evaluated the incidence of acne, acne as a reason for removal, and strategies used to manage acne after insertion of a progestin-only intrauterine device (IUD) or contraceptive implant in 1319 adolescents and young adults across four Adolescent Medicine LARC Collaborative study sites from January 2017 to June 2021.The mean age at insertion was 18.6 years.
  • Overall, 24% of participants had acne at the time of LARC insertion.
  • Worsening acne was defined as new patient reports of concern about acne, observations of acne, or addition of an acne medication after insertion; increased severity noted on an exam during follow-up or at the time of LARC removal; or acne reported as a side effect and/or reason for LARC removal.

TAKEAWAY: 

  • During the study period, 376 participants (28.5%) experienced worsening acne after LARC insertion, and 17% reported acne as a new concern, with no differences between those who received an IUD or an implant.
  • Only 44 of the 376 participants (11.7%) who reported worsening acne were being treated with an oral agent at follow-up.
  • Of the 542 individuals (41% of the total) who had the LARC device removed, 40 (7.4%) cited concerns about acne for removing the device, although just 5 (0.92%) said that acne was the only reason for removal. Of the 40 with concerns about acne when the device was removed, 18 (45%) had documented acne at the time of insertion.

IN PRACTICE:

The authors recommend that clinicians prescribing progestin-only LARC should counsel patients that acne may be a side effect, reassuring them that if they develop acne, “it typically is not problematic enough to warrant discontinuation,” and concluded that “concerns about the development or worsening of acne should not be cause to avoid these forms of contraception.”

SOURCE:

The study, led by Markus D. Boos, MD, PhD, of the division of dermatology in the Department of Pediatrics, University of Washington in Seattle and Seattle Children’s Hospital, was published in Pediatric Dermatology.

LIMITATIONS:

Individuals without documented acne were assumed to be acne-free, creating potential bias. Acne evaluation and treatment were not standardized and were not performed by dermatologists; acne severity was not recorded for many participants, possibly underestimating severity, and excluding LARC insertions without follow-up or with removal within 8 weeks may have underestimated the percentage of participants who developed new or worsening acne.

DISCLOSURES: 

The study was supported by Investigator-Initiated Studies Program of Organon and by the Health Resources and Services Administration of the US Department of Health and Human Services. Many authors received grants for this work. The authors did not disclose any other competing interests.

  • Of the 542 individuals (41% of the total) who had the LARC device removed, 40 (7.4%) cited concerns about acne for removing the device, although just 5 (0.92%) said that acne was the only reason for removal. Of the 40 with concerns about acne when the device was removed, 18 (45%) had documented acne at the time of insertion.

IN PRACTICE:

The authors recommend that clinicians prescribing progestin-only LARC should counsel patients that acne may be a side effect, reassuring them that if they develop acne, “it typically is not problematic enough to warrant discontinuation,” and concluded that “concerns about the development or worsening of acne should not be cause to avoid these forms of contraception.”

SOURCE:

The study, led by Markus D. Boos, MD, PhD, of the division of dermatology in the Department of Pediatrics, University of Washington in Seattle and Seattle Children’s Hospital, was published in Pediatric Dermatology.

LIMITATIONS:

Individuals without documented acne were assumed to be acne-free, creating potential bias. Acne evaluation and treatment were not standardized and were not performed by dermatologists; acne severity was not recorded for many participants, possibly underestimating severity, and excluding LARC insertions without follow-up or with removal within 8 weeks may have underestimated the percentage of participants who developed new or worsening acne.

DISCLOSURES: 

The study was supported by Investigator-Initiated Studies Program of Organon and by the Health Resources and Services Administration of the US Department of Health and Human Services. Many authors received grants for this work. The authors did not disclose any other competing interests.
