Screening for lung cancer can detect other health issues, as well.

The reason is because the low-dose CT scans used for screening cover the lower neck down to the upper abdomen, revealing far more anatomy than simply the lungs.

In fact, lung cancer screening can provide information on three of the top 10 causes of death worldwide: ischemic heart disease, chronic obstructive pulmonary disease, and, of course, lung cancer.

With lung cancer screening, “we are basically targeting many birds with one low-dose stone,” explained Jelena Spasic MD, PhD, at the European Lung Cancer Congress (ELCC) 2024.

Dr. Spasic, a medical oncologist at the Institute for Oncology and Radiology of Serbia in Belgrade, was the discussant on a study that gave an indication on just how useful screening can be for other diseases.

The study, dubbed 4-IN-THE-LUNG-RUN trial (4ITLR), is an ongoing prospective trial in six European countries that is using lung cancer screening scans to also look for coronary artery calcifications, a marker of atherosclerosis.

Usually, coronary calcifications are considered incidental findings on lung cancer screenings and reported to subjects’ physicians for heart disease risk assessment.

The difference in 4ITLR is that investigators are actively looking for the lesions and quantifying the extent of calcifications.

It’s made possible by the artificial intelligence-based software being used to read the scans. In addition to generating reports on lung nodules, it also automatically calculates an Agatston score, a quantification of the degree of coronary artery calcification for each subject.

At the meeting, which was organized by the European Society for Clinical Oncology, 4ITLR investigator Daiwei Han, MD, PhD, a research associate at the Institute for Diagnostic Accuracy in Groningen, the Netherlands, reported outcomes in the first 2487 of the 24,000 planned subjects.

To be eligible for screening, participants had to be 60-79 years old and either current smokers, past smokers who had quit within 10 years, or people with a 35 or more pack-year history. The median age in the study was 68.1 years.

Overall, 53% of subjects had Agatston scores of 100 or more, indicating the need for treatment to prevent active coronary artery disease, Dr. Han said.

Fifteen percent were at high risk for heart disease with scores of 400-999, indicating extensive coronary artery calcification, and 16.2% were at very high risk, with scores of 1000 or higher. The information is being shared with participants’ physicians.

The risk of heart disease was far higher in men, who made up 56% of the study population. While women had a median Agatston score of 61, the median score for men was 211.1.

The findings illustrate the potential of dedicated cardiovascular screening within lung cancer screening programs, Dr. Han said, noting that 4ITLR will also incorporate COPD risk assessment.

The study also shows the increased impact lung cancer screening programs could have if greater use were made of the CT images to look for other diseases, Dr. Spasic said.

4ITLR is funded by the European Union’s Horizon 2020 Program. Dr. Spasic and Dr. Han didn’t have any relevant disclosures.

An experimental therapeutic DNA vaccine against human papillomavirus type 16 (HPV16) was safe and well tolerated, and successfully cleared the virus in a majority of patients with HPV16-positive cervical intraepithelial neoplasia (CIN) 2 or 3 in a phase I trial.

The vaccine, pNGVL4a-CRTE6E7L2, also showed signs of efficacy in patients living with HIV, reported Kimberly Lynn Levinson, MD, MPH, associate professor of obstetrics and gynecology at Johns Hopkins Medicine in Baltimore.

“We demonstrated a 78% rate of clearance for both histologic regression and HPV16, with some clearance of other HPV types,” she said in an oral abstract presentation at the Society of Gynecologic Oncology’s Annual Meeting on Women’s Cancer, held in San Diego.

Further evaluation of the vaccine in vulvar, vaginal, and other tissue types is required, and evaluation of immune response at the local and systemic is ongoing, Dr. Levinson said.

In contrast to HPV16 prophylactic vaccines, which form an antibody-specific response to HPV, therapeutic vaccines elicit a cell-mediated immunity, primarily focusing on the virus’ E6 and E7 proteins.

There are currently only three Food and Drug Administration–approved therapeutic vaccines for cancer, but none are as yet approved for treatment of gynecologic malignancies.

According to the US National Institutes of Health, there are multiple therapeutic HPV vaccines in development using either vector-based, peptide and protein-based, or nucleic-acid based approaches, or whole cell (dendritic cell) approaches.
 

Current Study

Dr. Levinson noted that “DNA vaccines are both well tolerated and simple to produce, and the addition of calreticulin enhances immune response.”

The investigational vaccine is delivered via an electoporation device (TriGrid delivery system) that stimulates muscle at the injection site to produce an enhanced immune response.

In preclinical studies the device was associated with an enhanced immune response compared with standard intramuscular injection. The enhance immune effect persisted despite CD4 T cell depletion.

The investigators conducted a phase 1 dose-escalation study, administering the vaccine to two separate cohorts: women without HIV who had HPV16-positive cervical dysplasia (CIN 2/3) and women living with HIV with HPV16-positive cervical or vulvovaginal dysplasia (CIN 2/3, VIN 2/3 or VAIN 2/3).

The vaccine was delivered at weeks 0, 4, and 8, at doses of 0.3 mg, 1.0 mg, or 3.0 mg. At week 12, all patients underwent site-specific biopsy to verify non-progression.

At 6 months, the patients then underwent definitive treatment with either loop electro excision or vulvar/vaginal excision. At 12 months, all patients had standard evaluations with biopsies.

Dr. Levinson reported results for the first 14 women enrolled, 10 of whom were HIV-negative and 4 of whom were HIV-positive.

Of nine women in the HIV-negative arm who had completed 6-month visits and were evaluable, two had HPV16 clearance by 2-month follow-up, and seven had clearance at 6 months. Other HPV subtypes cleared in two of five patients at 3 months and in three of five at 6 months.

In addition, seven of nine patients in this arm had histologic regression at 6 months.

In the HIV-positive arm, the two patients with CIN had no HPV16 clearance at 3 months, but both had clearance at 16 months. The vaccine did not clear other HPV subtypes in these patients, however.

Of the two women in this arm who had VIN, one had HPV16 clearance and histologic regression at 6 months. The other patient had neither viral clearance nor histologic regression.

All participants tolerated each vaccine well. Adverse events were all grade 1 in severity and resolved within 4 weeks. The most common event was tenderness at the injection site. There were also three cases of mild headache, two cases of drowsiness, and one of nausea.
 

What’s Next?

In the question-and-answer session following the presentation, Ronald D. Alvarez, MD, MBA, chairman and clinical service chief of obstetrics and gynecology at Vanderbilt University Medical Center in Nashville, Tennessee, asked Dr. Levinson how the vaccine development will proceed.

“Obviously, you have more data to collect and analyze, but how are you going to move forward with what looks like equal efficacy between the 1 milligram and the 3 milligram doses? Are you just going to go with the maximum tolerated dose, or consider a lower dose if it shows equal efficacy in terms of histologic regression as well as HPV clearance?” he asked.

“This is something we’re very interested in, and we do plan for the dose-expansion phase to go with the higher dose,” Dr. Levinson replied. “We need to evaluate it further and we may need to do further randomization between the medium dose and the highest dose to determine if there are differences both with systemic and local responses.”

Robert DeBernardo, MD, section head of obstetrics and gynecology and the Women’s Health Institute at the Cleveland Clinic, asked whether Dr. Levinson and colleagues were considering evaluating the vaccine in transplant recipients, “because we have a lot of persistent HPV in that subgroup.”

Dr. Levinson said that one of the dose-expansion cohorts for further study is a population of patients scheduled for transplantation.

“What we’re interested in is looking at whether we can ‘cure’ HPV prior to transplantation, and we think that’s going to be the best way to show that this vaccine potentially eliminates the virus, because if we can eliminate the virus and then take a population that’s going to be immunodeficient, then that would show that there’s no reactivation of the virus,” she said.

The study is supported by the National Institutes of Health. Dr. Levinson, Dr. Alvarez, and Dr. DeBernardo had no conflicts of interest to report.

Adding low-dose radiation to the current standard first-line treatment, durvalumab plus etoposide-platinum chemotherapy, appears to improve survival outcomes in patients with extensive-stage small cell lung cancer (SCLC), suggested new findings from a small, single-arm study.

The analysis, presented at the 2024 European Lung Cancer Congress, revealed that low-dose radiation improved patients’ median progression-free and overall survival compared with standard first-line treatment, reported in a 2019 trial, lead author Yan Zhang, MD, reported.

The standard first-line treatment results came from the 2019 CASPIAN trial, which found that patients receiving the first-line regimen had a median progression-free survival of 5 months and a median overall survival of 13 months, with 54% of patient alive at 1 year.

The latest data, which included a small cohort of 30 patients, revealed that adding low-dose radiation to the standard first-line therapy led to a higher median progression-free survival of 8.3 months and extended median overall survival beyond the study follow-up period of 17.3 months. Overall, 66% of patients were alive at 1 year.

These are “promising” improvements over CASPIAN, Dr. Zhang, a lung cancer medical oncologist at Sichuan University, Chengdu, China, said at the Congress, which was organized by the European Society for Medical Oncology.

Study discussant Gerry Hanna, PhD, MBBS, a radiation oncologist at Belfast City Hospital, Belfast, Northern Ireland, agreed. Although there were just 30 patients, “you cannot deny these are [strong] results in terms of extensive-stage small cell cancer,” Dr. Hanna said.

Although standard first-line treatment of extensive-stage SCLC is durvalumab plus etoposide-platinum chemotherapy, the benefits aren’t durable for many patients.

This problem led Dr. Zhang and his colleagues to look for ways to improve outcomes. Because the CASPIAN trial did not include radiation to the primary tumor, it seemed a logical strategy to explore.

In the current single-arm study, Dr. Zhang and his team added 15 Gy radiation in five fractions to the primary lung tumors of 30 patients during the first cycle of durvalumab plus etoposide-platinum.

Subjects received 1500 mg of durvalumab plus etoposide-platinum every 3 weeks for four cycles. Low-dose radiation to the primary tumor was delivered over 5 days at the start of treatment. Patients then continued with durvalumab maintenance every 4 weeks until progression or intolerable toxicity.

Six patients (20%) had liver metastases at the baseline, and three (10%) had brain metastases. Over half had prophylactic cranial radiation. Performance scores were 0-1, and all but one of the participants were men.

Six- and 12-month progression-free survival rates were 57% and 40%, respectively. Overall survival was 90% at 6 months and 66% at 12 months. Median overall survival was 13 months in the CASPIAN trial but not reached in Dr. Zhang’s trial after a median follow-up of 17.3 months, with the earliest deaths occurring at 10.8 months.

Grade 3 treatment-related adverse events occurred in 80% of patients, most frequently hematologic toxicities. Five patients (16.7%) had severe adverse reactions to radiation. Although the overall dose of radiation was low, at 3 Gy each, the fractions were on the large side.

Hanna wanted more information on the radiotoxicity issue, but even so, he said that adding low-dose radiation to our durvalumab-chemotherapy doublet warrants further investigation.

Both Dr. Hanna and Dr. Zhang thought that instead of killing cancer cells directly, the greatest benefit of upfront radiation, and the peritumoral inflammation it causes, is to augment durvalumab’s effect.

Overall, Dr. Hanna stressed that we haven’t had results like these before in a SCLC study, particularly for novel agents, let alone radiation.

The study was funded by AstraZeneca, maker of durvalumab. Dr. Zhang and Dr. Hanna didn’t have any relevant disclosures.

The standard first-line treatment results came from the 2019 CASPIAN trial, which found that patients receiving the first-line regimen had a median progression-free survival of 5 months and a median overall survival of 13 months, with 54% of patient alive at 1 year.

The latest data, which included a small cohort of 30 patients, revealed that adding low-dose radiation to the standard first-line therapy led to a higher median progression-free survival of 8.3 months and extended median overall survival beyond the study follow-up period of 17.3 months. Overall, 66% of patients were alive at 1 year.

These are “promising” improvements over CASPIAN, Dr. Zhang, a lung cancer medical oncologist at Sichuan University, Chengdu, China, said at the Congress, which was organized by the European Society for Medical Oncology.

Study discussant Gerry Hanna, PhD, MBBS, a radiation oncologist at Belfast City Hospital, Belfast, Northern Ireland, agreed. Although there were just 30 patients, “you cannot deny these are [strong] results in terms of extensive-stage small cell cancer,” Dr. Hanna said.

Although standard first-line treatment of extensive-stage SCLC is durvalumab plus etoposide-platinum chemotherapy, the benefits aren’t durable for many patients.

This problem led Dr. Zhang and his colleagues to look for ways to improve outcomes. Because the CASPIAN trial did not include radiation to the primary tumor, it seemed a logical strategy to explore.

In the current single-arm study, Dr. Zhang and his team added 15 Gy radiation in five fractions to the primary lung tumors of 30 patients during the first cycle of durvalumab plus etoposide-platinum.

Subjects received 1500 mg of durvalumab plus etoposide-platinum every 3 weeks for four cycles. Low-dose radiation to the primary tumor was delivered over 5 days at the start of treatment. Patients then continued with durvalumab maintenance every 4 weeks until progression or intolerable toxicity.

Six patients (20%) had liver metastases at the baseline, and three (10%) had brain metastases. Over half had prophylactic cranial radiation. Performance scores were 0-1, and all but one of the participants were men.

Six- and 12-month progression-free survival rates were 57% and 40%, respectively. Overall survival was 90% at 6 months and 66% at 12 months. Median overall survival was 13 months in the CASPIAN trial but not reached in Dr. Zhang’s trial after a median follow-up of 17.3 months, with the earliest deaths occurring at 10.8 months.

Grade 3 treatment-related adverse events occurred in 80% of patients, most frequently hematologic toxicities. Five patients (16.7%) had severe adverse reactions to radiation. Although the overall dose of radiation was low, at 3 Gy each, the fractions were on the large side.

Hanna wanted more information on the radiotoxicity issue, but even so, he said that adding low-dose radiation to our durvalumab-chemotherapy doublet warrants further investigation.

Both Dr. Hanna and Dr. Zhang thought that instead of killing cancer cells directly, the greatest benefit of upfront radiation, and the peritumoral inflammation it causes, is to augment durvalumab’s effect.

Overall, Dr. Hanna stressed that we haven’t had results like these before in a SCLC study, particularly for novel agents, let alone radiation.

The study was funded by AstraZeneca, maker of durvalumab. Dr. Zhang and Dr. Hanna didn’t have any relevant disclosures.

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 melanoma, basal 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.

SAN DIEGO — 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.

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.

SAN DIEGO — 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.

Preliminary findings from a small case-control study at the Mayo Clinic in Rochester, Minnesota, suggest an association between diet and the development of spondyloarthritis (SpA), researchers reported in a poster at the Rheumatology Winter Clinical Symposium.

The small study involving 106 cases of incident spondyloarthritis matched 5:1 to individuals without SpA on the basis of age, sex, year, and geography found that risk was significantly higher with consumption of nondiet soda (adjusted odds ratio [aOR], 1.76), and with use of certain supplements: folate (aOR, 2.56), B vitamins (1.98), and fish oil (1.83). Moderate alcohol use ranging from two servings per month up to five per week was associated with a significantly lower risk of SpA (aOR, 0.63).

“We have seen an association between diet and RA. There is also strong literature showing an association between the microbiome and spondyloarthritis. Putting these two together, we wanted to see if the same was true for spondyloarthritis,” Vanessa Kronzer, MD, a rheumatologist at Mayo Clinic and a coauthor of the poster, said in an email. “Our results … do suggest an association between diet and developing spondyloarthritis as we suspected, for example, with soda.”

The researchers enrolled patients through the Mayo Clinic Biobank, which aims to engage a population-based sample of primary care patients, and administered questionnaires that assessed dietary and supplement exposures. They identified incident SpA using two diagnosis codes for ankylosing spondylitis or PsA ≥ 30 days apart along with use of disease-modifying antirheumatic drugs. To identify inflammatory bowel disease–associated SpAs, they used two diagnosis codes ≥ 30 days apart and age < 45 years. Follow-up questionnaires were administered 5 years later, Dr. Kronzer said.

Controls were matched on age, sex, year and geography. Logistic regression models adjusted for age, sex, race and ethnicity, education, and smoking, the researchers reported in their poster.

Dr. Kronzer and coauthors reported finding no significant associations with high-fat food, red meat, fish, poultry, diet soda, coffee and tea, and high alcohol use. They reported finding “trends of reduced risk with fruits and vegetables but higher risk with milk/dairy” and said these trends “should be replicated in larger studies.”

The 106 patients with incident spondyloarthritis had a mean age of 51. Three-fourths were female.

The research was funded by the Rheumatology Research Foundation and the National Institute of Arthritis and Musculoskeletal and Skin Diseases. Dr. Kronzer and coauthors did not report any disclosures.

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.

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.”

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.”

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.”
