SAN DIEGO — In the clinical opinion of Jenny E. Murase, MD, caring for patients with delusional infestation — the conviction that one is infested by animate or inanimate pathogens without medical or microbiological evidence of a true infestation — puts a dermatologist’s communication skills to the ultimate test.

“The fact that delusional infestation is a fixed, false belief [means] we will never agree with patients on the etiology by definition,” Dr. Murase, a dermatologist with the Palo Alto Foundation Medical Group, Mountain View, California, said at the annual meeting of the American Academy of Dermatology. “But somehow, we must come to some kind of an agreement on how to approach this therapeutically.”

Patients with delusional infestation (DI) often describe a cutaneous sensation of itching or crawling, biting, stinging — a pins and needles sensation. “Formication is when there’s a crawling sensation on the surface of the skin,” she said. “That’s something we can agree on — the fact that there is a shared understanding that they’re experiencing some kind of sensation in their skin.”

First described in 1894, several different terms have been used to describe DI in the past, including acarophobia, delusions of parasitosis, Ekbom syndrome, and Morgellons disease. The current term used for DI includes other animate or inanimate pathogens besides parasites.

The average dermatologist manages two to three patients with DI every 5 years, “so it’s not uncommon,” said Dr. Murase, who also holds a faculty position in the department of dermatology at the University of California, San Francisco. Females are about 2.5 times more likely to be affected compared with males, she said, and 8%-12% of patients with DI have a friend or relative who shares the symptom, and they often accompany them to the office visit. “Initially, you’re trying to determine if this a primary condition where it’s only the cutaneous condition the patient is experiencing, or if there is a secondary condition like an underlying psychiatric disorder or medical condition or drug use that contributes to the sensation,” she said.

According to a descriptive study of 115 patients with DI, 50% had at least one drug detected in hair samples, and nearly 60% had evidence of some cognitive impairment that could not be explained by deficits in IQ. Another study of 147 patients with DI seen at the Mayo Clinic between 2001 and 2007 found that 81% had a prior psychiatric condition and 26% had a shared psychotic disorder.
 

Phased Approach to Treatment

Dr. Murase discussed her phased approach to caring for patients with DI, based on a review article that she and colleagues published in the International Journal of Dermatology. Phase 1 involves preparing for the visit by asking staff to refer to patients with DI as VIPs and allowing them to talk freely about the sensation they’re experiencing. “The goal is to improve the patient’s condition, not to convince the patient that he or she is delusional,” Dr. Murase explained. “Many patients can’t distinguish between when they’re talking to the doctor and when they’re talking to a nurse or a nurse practitioner; they like to feel that they’re being heard and listened to.”

She also recommends scheduling patients with DI for the end of the day and arranging frequent follow-up visits. “Making them feel valued is the bottom line,” she emphasized. “Remember: They’re less likely to respect socially defined boundaries like time constraints, so you do have to set boundaries, and don’t take what they may say to you personally. You’re not going to be able to care for that individual unless you do that. They may appear defiant, frustrated, and angry, but the fact that they showed up in your office means that you can help that person.”

Phase 2 of care for these patients consists of building a therapeutic rapport by greeting them with a smile and positive attitude and using welcoming body language such as sitting side-by-side during the office visit as opposed to face-to-face, “so it’s a less aggressive approach,” she said. Next, ask about their goal with a question such as, “Is it more important for you to find the bug/virus or to improve your condition?”

During the visit, “you’re continually shifting from etiology — which they are desperate to understand — to a shared desire for treatment,” Dr. Murase said. “No one knows what causes DI and remember, in medicine we treat patients when the exact etiology is unknown. So, we’re not doing anything that differently. Focus on the effect that the symptoms are having on their life. Say something like, ‘it must be so miserable to be living this way. I really want to help you.’ ”

Phase 3 of care for patients with DI involves performing a thorough history and physical exam. The initial office visit should include a full body exam to rule out any underlying dermatologic condition that may be causing the sensation they’re complaining about. She cited a retrospective study of 108 patients who presented to the Mayo Clinic with DI as the main reason for their office visit. Of the 80 patients who had a biopsy, 61% had chronic dermatitis; 48% had excoriation, ulceration, or erosion; and 31% had nonspecific dermal inflammation.

Whether to perform a biopsy or not is controversial, Dr. Murase added, because it’s probably not going to change the clinical impression or diagnosis. “If you agree to do the biopsy, get a verbal contract with the patient,” she advised. “You might say, ‘We’re going to do this. You’re going to choose the site, we’re going to do a biopsy, but we are going to be in agreement here that, if we can’t find the etiology, that you will still be open to going on therapy.’ This is important because it establishes a therapeutic alliance.”

Since patients with DI often bring in their own specimens, she also recommends providing them with microscope glass slides without cover slips and asking them to use clear tape, not tape that is opaque or matted, to cover the specimen.

To rule out other illnesses and conditions that could be triggering the perceived DI, she said lab tests to consider include a complete blood count, comprehensive metabolic panel, thyroid-stimulating hormone, calcium, hemoglobin A1c, vitamin B12, urinalysis, toxicology screen, HIV/hepatitis C, and rapid plasma reagin.
 

Starting Treatment

Phase 4 of care for patients with DI involves initiating therapy, which includes demonstrating empathy by reflecting on the detrimental effects of the patient’s reported sensations on their quality of life. “Emphasize that you are not questioning their experience, and that you don’t doubt that they feel things on their skin,” Dr. Murase said. “Recommend medications on an empirical or ‘trial and error’ pragmatic basis. I often tell patients, ‘I will never give up on you if you will never give up on me.’”

For treating patients with DI, her first-generation antipsychotic of choice is pimozide. She starts at a dose of 0.5 mg, building up to 2-3 mg once a day. Haloperidol is another option: 0.5 mg to start, building up to 1-5 mg every night at bedtime. “This requires monitoring for bone suppression via CBC and hypermetabolic complications via fasting lipids and HbA1c,” she said. “There is also an increased risk of prolonged QT with pimozide and risk of extrapyramidal symptoms and tardive dyskinesia.”

Second-generation antipsychotics to consider include risperidone (0.5 mg to start, building up to 102 mg at bedtime); olanzapine (2.5 mg to start, building up to 5-10 mg at bedtime); aripiprazole (2-5 mg to start, building up to 10-15 mg a day), and quetiapine (12.5 mg to start, building up to 200 mg at bedtime).

For all medical therapy she recommends starting patients with a low dose, increasing by 0.5 mg every 2-3 weeks, and let them be “stable and comfortable” for 3-4 months, and then taper down the dose by 0.5 mg every 2-4 weeks or more slowly. In the medical chart, Dr. Murase recommends avoiding use of the terms “psychosis” and “delusions.” Instead, “formication” (tactile hallucination of insects crawling on or within the skin) or “cutaneous dysesthesia” are better terms if patients access their records, she said.

Dr. Murase reported having no relevant disclosures.

SAN DIEGO — In the opinion of Patricia A. Treadwell, MD, providing health equity in dermatology means providing support for everyone, regardless of their financial circumstances or their skin color.

It also means embracing diversity, which she defined as diversity of thinking. “If you look at the literature, diversity in higher education and health profession training settings is associated with better educational outcomes for all students,” Dr. Treadwell, professor emeritus of dermatology and pediatrics at Indiana University School of Medicine, Indianapolis, said in a presentation on health equity during the plenary session at the annual meeting of the American Academy of Dermatology. “Each person brings a variety of experiences and perspectives. This provides a wide range of opinions and different ways to look at things. Racial and ethnic minority providers can help health organization reduce cultural and linguistic barriers and improve cultural competence.”

Dr. Treadwell

Such efforts matter, she continued, because according to the United States Census, Black individuals make up 13.6% of the population, while Latinx individuals represent 19.1% of the population. “So, melanin matters,” she said. “If you look at a dermatology textbook, a high percentage [of cases] are identified as Caucasian individuals, which results in an overrepresentation of Caucasians in photographs. That can result in delayed or missed diagnoses [in different skin types]. If you are contributing to cases in textbooks, make sure you have a variety of different skin types so that individuals who are referring to the textbooks will be more equipped.”

Practicing dermatologists can support diversity by offering opportunities to underrepresented in medicine (URM) students, “African-American students, Hispanic students, and Native American students,” said Dr. Treadwell, who was chief of pediatric dermatology at Riley Hospital for Children in Indianapolis from 1987 to 2004. “You also want to be encouraging,” she said.

Dermatologists can also support diversity by providing precepting opportunities, “because many [medical] students may not have connections and networks. Providing those opportunities is important,” she said. Another way to help is to be a mentor to young dermatologists. “I certainly have had mentors in my career who have been very helpful,” she said. “They’ve given me advice about things I was not familiar with.”

Dr. Treadwell suggested the Skin of Color Society as an organization that can assist with networking, mentoring, and research efforts. She also cited the Society for Pediatric Dermatology’s Equity, Diversity, and Inclusion Committee, formed in 2020. One of its initiatives was assembling a special issue of Pediatric Dermatology dedicated to DEI issues, which was published in November 2021.

Dr. Treadwell concluded her presentation by encouraging dermatologists to find ways to care for uninsured or underinsured patients, particularly those with skin of color. This might involve work at a county hospital “to provide access, to serve the patients ... and helping to decrease some the issues in terms of health equity,” she said.

Dr. Treadwell reported having no relevant disclosures. At the plenary session, she presented the John Kenney Jr., MD Lifetime Achievement Award and Lectureship.

SAN DIEGO — When Jennifer Adams, MD, recently entered the search term “warts” on the ClinicalTrials.gov web site, nearly 240 results popped up.

“There is a lot of research activity around this topic,” Dr. Adams, vice chair of the department of dermatology at the University of Nebraska Medical Center, said at the annual meeting of the American Academy of Dermatology. “We just don’t have fantastic, well-run trials on many of the currently available treatments.”

In a 2012 Cochrane review on the topical treatment of non-genital cutaneous warts, authors drew from 85 trials involving 8,815 randomized patients. They found that most warts spontaneously resolved, and the authors determined salicylic acid to be safe and modestly beneficial. Specifically, trials of salicylic acid (SA) versus placebo showed that the former significantly increased the chance of clearance of warts at all sites (risk ratio, 1.56, 95% confidence interval [CI], 1.20-2.03). A meta-analysis of cryotherapy versus placebo for warts at all sites favored neither intervention nor control (RR, 1.45, 95% CI, 0.65-3.23).

“The authors determined that there is less evidence for cryotherapy but stated that it may work when salicylic acid does not, or in combination with salicylic acid,” Dr. Adams said. “However, salicylic acid and cryotherapy don’t do enough for our patients [with warts]. There are a lot of situations where we need to reach further into the toolbox.”

A 2021 review article listed many options for managing difficult-to-treat warts, including intralesional Candida antigen, intralesional measles-mumps-rubella (MMR), intralesional HPV vaccine, intralesional vitamin D, intralesional cidofovir, intralesional bleomycin, and intralesional 5-FU injections, and topical vitamin D, topical cidofovir, and topical bleomycin. According to Dr. Adams, clinical data exist for cidofovir and vitamin D but studies evaluated different formulations, doses, sites of administration, and limited randomized controlled trials.

“Intralesional cidofovir is more effective than the topical form, but intralesional cidofovir can be painful and both forms are expensive,” she said. “Topical vitamin D is less likely to cause dyspigmentation compared to other available treatments, so it’s a great option in skin of color, but it has been less effective compared to some of our other topical treatments.”

Newer Options Promising

On the horizon, berdazimer gel was approved in January of 2024 for the treatment of molluscum but results from trials of its use for extragenital warts are encouraging. Another promising option is topical ionic contraviral therapy (ICVT) with digoxin and furosemide combined, which inhibits cellular potassium influx. A phase 2a randomized controlled trial of 80 adults found a statistically significant reduction in the diameter of cutaneous warts among those who received ICVT compared with those who received placebo (P = .002). “It’s cheap and well tolerated,” Dr. Adams added.

Intralesional approaches to treating warts offer another alternative. A 2020 review of 43 articles concluded that intralesional treatments for warts have equal or superior efficacy to first-line salicylic acid or cryotherapy.

Dr. Adams said that she considers intralesional treatments such as vitamin D, MMR vaccine antigen, and Candida antigen for refractory, numerous, or distant site warts. “Injecting the MMR vaccine into the largest wart every 2 weeks has been found to lead to complete clearance in 60%-68% of cases in one study,” she said. “The benefit is that it’s $21 per dose, which is nice, but as with any vaccination, patients can develop flu-like symptoms as side effects.”

Use of the HPV vaccine for treating cutaneous warts remains controversial, she continued, but it seems to work better in younger patients. In one open-label study that evaluated the HPV vaccine for the treatment of multiple recalcitrant warts, with doses administered at 0. 2, and 6 months, the response rate 3 months after the third dose was 55% among those older than age 26, compared with 84% among those ages 9-26 years.

Another option, intralesional cidofovir, has been shown to be especially effective for refractory warts. “It has also been shown to work for warts in immunocompetent and immunocompromised patients,” Dr. Adams said.

In the realm of adjuvant treatments, microneedling has been found to have similar efficacy to needling, Dr. Adams said, but with minimal pain. “When we combine it with topical treatments like 5-FU, it’s even more efficacious,” she said.

One study found that combining microneedling with topical 5-FU had clearance similar to that of intralesional 5-FU or microneedling alone, but involved fewer treatment sessions and less pain in the combination group.

Autoinoculation has been used to stimulate an immune response in patients with warts, leading to clearance rates of 4% (mild clearance) to 66% (complete clearance) in one study. “We would expect this to work better in immunocompetent patients, but it’s something to keep in mind if you’re limited in the medications you can get for a patient,” Dr. Adams said. Also, results from a systematic review and meta-analysis suggest that systemic retinoids combined with intralesional immunotherapy leads to higher clearance rates and lower rates of recurrence of warts. The top performer among those tested was acitretin plus Candida antigen.

Dr. Adams advised dermatologists who try alternatives to salicylic acid and cryotherapy for warts to be “wary of a lack of high-level evidence” for their use. “They can be helpful for patients who have failed traditional therapies or have a contraindication to the usual go-tos.”

She reported having no relevant financial disclosures.

SAN DIEGO — When Jennifer Adams, MD, recently entered the search term “warts” on the ClinicalTrials.gov web site, nearly 240 results popped up.

“There is a lot of research activity around this topic,” Dr. Adams, vice chair of the department of dermatology at the University of Nebraska Medical Center, said at the annual meeting of the American Academy of Dermatology. “We just don’t have fantastic, well-run trials on many of the currently available treatments.”

In a 2012 Cochrane review on the topical treatment of non-genital cutaneous warts, authors drew from 85 trials involving 8,815 randomized patients. They found that most warts spontaneously resolved, and the authors determined salicylic acid to be safe and modestly beneficial. Specifically, trials of salicylic acid (SA) versus placebo showed that the former significantly increased the chance of clearance of warts at all sites (risk ratio, 1.56, 95% confidence interval [CI], 1.20-2.03). A meta-analysis of cryotherapy versus placebo for warts at all sites favored neither intervention nor control (RR, 1.45, 95% CI, 0.65-3.23).

SAN DIEGO — A novel formulation of polidocanol, an injectable synthetic non-ionic detergent that is approved by the US Food and Drug Administration (FDA) for sclerotherapy, may have a role in excess submental fat reduction, results from a phase 2b trial demonstrated.

The solution, also known as 10XB101, “has been demonstrated to cause adipolysis,” Kavita Darji, MD, an American Society for Dermatologic Surgery (ASDS) cosmetic and dermatologic laser surgery fellow at a practice in San Diego, said during a late-breaking session at the annual meeting of the American Academy of Dermatology. “It shows less inflammation and release of cytokines TNF-alpha and MCP-1 by macrophages than deoxycholic acid, which is currently used for submental fat reduction.”

Dr. Darji

In a phase 2b clinical trial conducted at four sites, investigators enrolled 51 patients and assigned them to one of four dose cohorts: 2%, 3%, or 4.5% 10XB101, or vehicle. Each treatment consisted of up to 50 injections at 0.2 mL per injection, and they were administered up to six times 4 weeks apart. Study endpoints included a composite of the Clinician Submental Fat Score (CSFS) and Patient Submental Fat Score (PSFS) on a 0-4–point scale. The researchers graded local skin reactions such as erythema, edema, tenderness on palpation, bruising, pain, and burning/stinging as 0 (none), 1 (mild), 2 (moderate), or 3 (severe). They also obtained lab tests and performed electrocardiograms.

Dr. Darji and colleagues analyzed two populations: the intent to treat (ITT) population, which included all 51 enrolled subjects who received any injection of the test agent, and a completer population of 40 subjects. “These patients had at least four treatments or completed the treatments per protocol, completed the 4 weeks after final treatment assessments, or did not have any significant protocol deviations that would impact the evaluation of efficacy,” she explained.

To compare how 10XB101 performed compared with deoxycholic acid (Kybella), which is approved by the FDA to improve the appearance of moderate to severe submental fat, the researchers drew from pooled findings of Refine 1 and 2, in which adults received up to six treatment sessions with deoxycholic acid or placebo.

The ITT analysis of the 3% and 4.5% 10XB101 dose groups showed about a fourfold increase in a 2-grade or better improvement in the composite endpoint relative to the pooled findings of deoxycholic acid (62% vs. 16%, respectively). In addition, 80% of the completer population achieved a 2-grade improvement in the composite endpoint. “Importantly, 10% to 33% also received a 3-grade improvement, depending on the dose they were assigned to,” Dr. Darji said.

On average, patients in both cohorts achieved a 1-grade improvement after two treatments, and about 50% achieved a 2-grade improvement after four treatments — which is consistent with a more rapid onset when compared with deoxycholic acid, she said.

Both study endpoints were achieved by 31% of patients in the ITT group vs. 33% of completers, respectively, with the 2% dose; 62% vs. 80% with the 3% dose; and 54% vs. 79% for the 4.5% dose. “This is a 2- to 5-times increase in success” when compared with the results of deoxycholic acid in the published pooled analysis, Dr. Darji said. The researchers measured adverse events by spontaneous and elicited reports and by assessments of recorded local skin reactions. They found that 80% of all measured local skin reactions rated as 0 while 98% of all measured local skin reactions rated as a 0 or 1. One myocardial infarction occurred, which was mild and resolved. This case was not related to the study drug, Dr. Darji said in an interview after the meeting. Otherwise, no safety laboratory or ECG signals were noted.

In findings limited to the 3% dose of 10XB101, mild bruising occurred in 8% of patients at postinjection visit 2, 18% of those at postinjection visit 3, 20% of those at postinjection visit 4, and in 20% of those at postinjection visit 5. Reports of mild pain/burning/stinging occurred in 8% of patients at postinjection visit 2 but at no other subsequent visits. Meanwhile, edema occurred in 42% of patients at postinjection visit 2, 45% of those at postinjection visit 3, 50% of those at postinjection visits 4 and 5, and 38% of those at postinjection visit 6.

“Patients resumed normal activity within 1-3 days and had fewer side effects that lasted longer than 30 days,” Dr. Darji concluded, adding that the results “imply a potential opportunity to expand the treatment to other anatomic areas, which is a future direction.”

One of the session moderators, Andrew Blauvelt, MD, MBA, of Oregon Medical Research Center, Portland, noted that the study was not a head-to-head trial of polidocanol vs. deoxycholic acid, so he cautioned against drawing strong conclusions about the comparative data presented.

Asked to comment on the results Lawrence J. Green, MD, of the department of dermatology at George Washington University, Washington, said that 10XB101 “showed excellent efficacy with much fewer adverse events when compared to what we found in studies with Kybella, the only currently FDA-approved injection for submental fat reduction.”

Dr. Green

In addition, “much less pain after injection was to me the most obvious differentiator between this and Kybella studies. I look forward to seeing if larger studies confirm the efficacy and safety from this phase 2 study, as 10XB101 has potential to be a more effective, and safer option to reduce submental fat,” he added. He was not involved with the study.

Dr. Darji reported having no disclosures. Mitchel P. Goldman, MD, the study’s lead investigator, is a minority investor in 10XBio, which is developing 10XB101. Dr. Blauvelt and Dr. Green disclosed conflicts of interest from many pharmaceutical companies.

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.

SAN DIEGO — 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.”

“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.

SAN DIEGO — 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.”

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.”

SAN DIEGO — 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.

SAN DIEGO — 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.”

“We will see if phase 3 trials with more balanced demographics across remibrutinib and placebo arms will reproduce these outcomes,” she continued, “It is exciting to see this potential new medication for HS under continued investigation, especially in light of the current gap in oral therapeutic options for the HS patient community.” Dr. Hsiao was not involved with the study.

Dr. Kimball disclosed numerous conflicts of interest from various pharmaceutical companies, including the receipt of research grants and consulting fees from Novartis. Dr. Hsiao disclosed that she is a member of the board of directors for the Hidradenitis Suppurativa Foundation. She has also served as a consultant for AbbVie, Aclaris, Boehringer Ingelheim, Incyte, Novartis, and UCB; as a speaker for AbbVie, Novartis, and UCB; and as an investigator for Amgen, Boehringer Ingelheim, and Incyte.

SAN DIEGO — 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.

SAN DIEGO — After 24 weeks of treatment with subcutaneously administered sonelokimab 120 mg, about 43% of patients with moderate to severe hidradenitis suppurativa (HS) achieved a Hidradenitis Suppurativa Clinical Response (HiSCR75), defined as at least a 75% reduction in total abscess and inflammatory nodule (AN) count with no increase in abscess or draining tunnel count relative to baseline, results from a randomized clinical trial showed.

Sonelokimab is a novel humanized nanobody that selectively binds to interleukin (IL)-17A and IL-17F, presenting author Brian Kirby, MD, a dermatologist at St. Vincent’s Private Hospital, Dublin, Ireland, said during a late-breaking abstract session at the annual meeting of the American Academy of Dermatology. Sonelokimab is smaller than traditional monoclonal antibodies, he said, “which means it may be able to penetrate tissues better and stay there longer.” It is being developed by MoonLake Immunotherapeutics, based in Zug, Switzerland

Ted Bosworth/MDedge News

According to a press release from the company, nanobodies represent a new generation of targeted therapies derived from antibodies. They consist of one or more domains based on the small antigen-binding variable regions of heavy-chain-only antibodies.

In a phase 2 study known as the MIRA trial, researchers recruited 234 patients with moderate to severe HS to evaluate two different doses of sonelokimab (120 mg and 240 mg every 2 weeks) with a placebo control arm and adalimumab as an active reference arm. The primary endpoint of was the percentage of participants who achieved a HiSCR75. The study population included adults with Hurley Stage II or III HS who had HS lesions in 2 or more anatomical areas and a total abscess and inflammatory nodule (AN) count of 5 or more lesions; and had been treated with 2 or fewer biologics.

Dr. Kirby reported results from 67 patients in the sonelokimab 120 mg arm, 66 in the sonelokimab 240 mg arm, and 39 in the placebo arm. “It’s worth noting that the baseline AN count ranged between 12 and nearly 15, the mean draining tunnel count ranged between 2.9 and 3.7, and between 7% and 13% of patients were on concomitant antibiotics,” he said.

At 24 weeks, 43.3% of patients in the sonelokimab 120 mg arm achieved a HiSCR 75, compared with 34.8% of those in the sonelokimab 240 mg arm and 14.7% of those in the placebo arm, he reported. Meanwhile, 65.7% of patients in the sonelokimab 120 mg arm achieved an HiSCR 75, compared with 53% of those in the sonelokimab 240 mg arm and 27.9% of those in the placebo arm. Discontinuation rates were low and similar between treatment arms, with fewer than 10% of patients failing to complete week 24 of treatment.

In other findings, 69% of patients in the 120 mg arm achieved a HiSCR 50 at week 24 compared with 60.3% in the 240 mg arm; 56.9% in the 120 mg arm achieved a HiSCR 75 compared with 37.9% in the 240 mg arm; and 37.9% in the 120 mg arm achieved a HiSCR 75 compared with 27.6% in the 240 mg arm.

In addition, complete inflammatory remission as defined by the International HS Severity Score System (IHS4-100) continued to increase to week 24, with 24.1% of patients in the 120 mg arm achieving complete remission, compared with 15.5% of those in the 240 mg arm. Meaningful improvements in quality of life, skin pain, and HS symptoms reported by patients treated with sonelokimab were maintained or increased to week 24. Specifically, more than 60% of patients had a meaningful clinical improvement in their Dermatology Life Quality Index, over 45% had a minimum of a 30% increase in the Numerical Rating Scale **30, and more than 41% of patients reported absent or minimal symptoms on the Patient’s Global Impression of their Disease Severity, “which is a high bar to achieve in HS,” Dr. Kirby said.
 

No Serious Safety Signals Noted

There were no unexpected safety signals to week 24. The incidence of treatment-related adverse events was low, and there were no cases of inflammatory bowel disease. There were no serious infections, no major adverse cardiovascular event (MACE) reports, and no significant abnormalities on liver function tests. “There were also no safety signals on suicidal behavior, attempted suicides, or completed suicides,” he said.

“As you would expect with in IL-17 inhibitor, there was a signal for candidiasis, but all cases were judged to be mild or moderate, and no cases led to discontinuation of treatment from the trial because of candidal infection.”

Based on these data, Dr. Kirby said that larger and longer-term phase 3 trials are planned to further examine the safety and efficacy of sonelokimab at the 120 mg dose for the treatment of moderate-to-severe HS.

One of the session moderators, Joel M. Gelfand, MD, professor of dermatology and epidemiology at the University of Pennsylvania, Philadelphia, asked Dr. Kirby why he thought the lower dose resulted in generally better outcomes compared with the higher dose.

“There were no statistically significant differences between the two groups,” Dr. Kirby responded. “The 120 mg dose we know is highly effective in psoriasis, so there may be a ceiling effect. This may also be due to population variability, but the bottom line is that the 120 mg dose performs extremely well.”

Dr. Kirby disclosed that he has received research support from/has been a principal investigator for several pharmaceutical companies, including MoonLake Immunotherapeutics. Dr. Gelfand reported that he has been a consultant to and/or a member of the data safety monitoring board member for several pharmaceutical companies, including MoonLake.

Dr. Kirby reported results from 67 patients in the sonelokimab 120 mg arm, 66 in the sonelokimab 240 mg arm, and 39 in the placebo arm. “It’s worth noting that the baseline AN count ranged between 12 and nearly 15, the mean draining tunnel count ranged between 2.9 and 3.7, and between 7% and 13% of patients were on concomitant antibiotics,” he said.

At 24 weeks, 43.3% of patients in the sonelokimab 120 mg arm achieved a HiSCR 75, compared with 34.8% of those in the sonelokimab 240 mg arm and 14.7% of those in the placebo arm, he reported. Meanwhile, 65.7% of patients in the sonelokimab 120 mg arm achieved an HiSCR 75, compared with 53% of those in the sonelokimab 240 mg arm and 27.9% of those in the placebo arm. Discontinuation rates were low and similar between treatment arms, with fewer than 10% of patients failing to complete week 24 of treatment.

In other findings, 69% of patients in the 120 mg arm achieved a HiSCR 50 at week 24 compared with 60.3% in the 240 mg arm; 56.9% in the 120 mg arm achieved a HiSCR 75 compared with 37.9% in the 240 mg arm; and 37.9% in the 120 mg arm achieved a HiSCR 75 compared with 27.6% in the 240 mg arm.

In addition, complete inflammatory remission as defined by the International HS Severity Score System (IHS4-100) continued to increase to week 24, with 24.1% of patients in the 120 mg arm achieving complete remission, compared with 15.5% of those in the 240 mg arm. Meaningful improvements in quality of life, skin pain, and HS symptoms reported by patients treated with sonelokimab were maintained or increased to week 24. Specifically, more than 60% of patients had a meaningful clinical improvement in their Dermatology Life Quality Index, over 45% had a minimum of a 30% increase in the Numerical Rating Scale **30, and more than 41% of patients reported absent or minimal symptoms on the Patient’s Global Impression of their Disease Severity, “which is a high bar to achieve in HS,” Dr. Kirby said.
 

No Serious Safety Signals Noted

There were no unexpected safety signals to week 24. The incidence of treatment-related adverse events was low, and there were no cases of inflammatory bowel disease. There were no serious infections, no major adverse cardiovascular event (MACE) reports, and no significant abnormalities on liver function tests. “There were also no safety signals on suicidal behavior, attempted suicides, or completed suicides,” he said.

“As you would expect with in IL-17 inhibitor, there was a signal for candidiasis, but all cases were judged to be mild or moderate, and no cases led to discontinuation of treatment from the trial because of candidal infection.”

Based on these data, Dr. Kirby said that larger and longer-term phase 3 trials are planned to further examine the safety and efficacy of sonelokimab at the 120 mg dose for the treatment of moderate-to-severe HS.

One of the session moderators, Joel M. Gelfand, MD, professor of dermatology and epidemiology at the University of Pennsylvania, Philadelphia, asked Dr. Kirby why he thought the lower dose resulted in generally better outcomes compared with the higher dose.

“There were no statistically significant differences between the two groups,” Dr. Kirby responded. “The 120 mg dose we know is highly effective in psoriasis, so there may be a ceiling effect. This may also be due to population variability, but the bottom line is that the 120 mg dose performs extremely well.”

Dr. Kirby disclosed that he has received research support from/has been a principal investigator for several pharmaceutical companies, including MoonLake Immunotherapeutics. Dr. Gelfand reported that he has been a consultant to and/or a member of the data safety monitoring board member for several pharmaceutical companies, including MoonLake.

SAN DIEGO — After 24 weeks of treatment with subcutaneously administered sonelokimab 120 mg, about 43% of patients with moderate to severe hidradenitis suppurativa (HS) achieved a Hidradenitis Suppurativa Clinical Response (HiSCR75), defined as at least a 75% reduction in total abscess and inflammatory nodule (AN) count with no increase in abscess or draining tunnel count relative to baseline, results from a randomized clinical trial showed.

Sonelokimab is a novel humanized nanobody that selectively binds to interleukin (IL)-17A and IL-17F, presenting author Brian Kirby, MD, a dermatologist at St. Vincent’s Private Hospital, Dublin, Ireland, said during a late-breaking abstract session at the annual meeting of the American Academy of Dermatology. Sonelokimab is smaller than traditional monoclonal antibodies, he said, “which means it may be able to penetrate tissues better and stay there longer.” It is being developed by MoonLake Immunotherapeutics, based in Zug, Switzerland

According to a press release from the company, nanobodies represent a new generation of targeted therapies derived from antibodies. They consist of one or more domains based on the small antigen-binding variable regions of heavy-chain-only antibodies.

In a phase 2 study known as the MIRA trial, researchers recruited 234 patients with moderate to severe HS to evaluate two different doses of sonelokimab (120 mg and 240 mg every 2 weeks) with a placebo control arm and adalimumab as an active reference arm. The primary endpoint of was the percentage of participants who achieved a HiSCR75. The study population included adults with Hurley Stage II or III HS who had HS lesions in 2 or more anatomical areas and a total abscess and inflammatory nodule (AN) count of 5 or more lesions; and had been treated with 2 or fewer biologics.
