Biomarkers in Cord Blood May Predict AD Onset in Newborns, Study Suggests
TOPLINE:
and interleukin (IL) 31.
METHODOLOGY:
- Researchers conducted a prospective study to evaluate the predictive role of serologic biomarkers and cutaneous markers and the development of AD in 40 full-term newborns from a university hospital in Italy.
- Cord blood was collected at birth and analyzed for serum biomarkers such as CCL17/TARC and IL-31.
- TEWL and skin hydration rates were measured at 1, 6, and 12 months, and dermatological features such as dryness, cradle cap, and eczematous lesions were also monitored during visits.
TAKEAWAY:
- At 6 months, 16 infants had symptoms of AD, which included dry skin, pruritus, and keratosis pilaris, which persisted at 12 months. Their mean Eczema Area and Severity Index score was 6.6 at 6 months and 2.9 at 12 months.
- Infants with signs of AD had significantly higher TEWL levels at the anterior cubital fossa at 1, 6, and 12 months than those without AD.
- Cord blood levels of CCL17/TARC and IL-31 were significantly higher in infants with AD.
- A correlation was found between TEWL values and CCL17 levels at 1, 6, and 12 months.
IN PRACTICE:

Elinzanetant Shows Significant Improvement in Menopausal Vasomotor and Sleep Symptoms
CHICAGO — The nonhormonal investigational drug elinzanetant led to significant improvement in hot flashes as well as sleep disturbance and quality of life, according to data from three randomized controlled trials presented at The Menopause Society 2024 Annual Meeting in Chicago. Two phase 3 trials, OASIS 1 and 2, were also published in JAMA, and the longer-term OASIS 3 trial was presented as a poster at the conference.
Elinzanetant is a selective neurokinin (NK) receptor antagonist, similar to fezolinetant, the first drug in this class approved by the US Food and Drug Administration (FDA) for vasomotor symptoms in May 2023. This class of medications targets the estrogen-sensitive kisspeptin/NK B/dynorphin (KNDy) neurons thought to play a role in thermoregulation and hot flashes during menopause. While fezolinetant targets only the NK-3 receptor, elinzanetant is a dual NK receptor antagonist that targets both NK-1 and NK-3. Bayer submitted a New Drug Application for elinzanetant to the FDA on August 1.
For those in whom hormone therapy is contraindicated, “it’s always been difficult for women with really severe symptoms to have a safe and effective therapy,” lead author JoAnn Pinkerton, MD, a professor of ob.gyn. at the University of Virginia in Charlottesville, Virginia, told this news organization. “The nonhormonal therapies we’ve used mostly off-label — the antidepressants, gabapentin, clonidine, oxybutynin — do help the hot flashes, but they don’t work nearly as effectively as these new NK receptor antagonists, and having one that looks like it might have a broader use for hot flashes, night sweats, mood, and sleep is just really exciting.”
Dr. Pinkerton said approximately 80% of the women in the OASIS 1 and 2 studies had at least a 50% reduction in hot flashes. “It was a very strong, dramatic positive finding, but the improvements in sleep and mood have really encouraged us to go further,” she said.
Declining estrogen levels during and after menopause can cause hypertrophy and hyperactivity of the KNDy neurons, which has been linked to thermoregulation disruptions that may trigger hot flashes, James Simon, MD, a clinical professor of ob.gyn. at The George Washington University School of Medicine & Health Sciences and medical director of IntimMedicine in Washington, DC, told attendees. He presented pooled data from OASIS 1 and 2. The NK-1 receptor, targeted by elinzanetant but not fezolinetant, is also thought to play a role in insomnia and possibly in mood.
“Oftentimes the focus on a lot of these drugs is hot flashes, hot flashes, hot flashes, but we know hot flashes do not occur in isolation,” Chrisandra Shufelt, MD, professor and chair of general internal medicine and associate director of the Women’s Health Research Center at Mayo Clinic in Jacksonville, Florida, told this news organization. Elinzanetant is “an interesting compound because it actually works on sleep, and that was critical because sleep disturbance precedes” many other menopausal symptoms, said Dr. Shufelt, who was not involved in the study.
“I think it is an outstanding option for women who don’t have the opportunity to get hormones,” Dr. Shufelt said, and she was particularly pleased to see there were no safety concerns for the liver in the trial data. The FDA issued a warning on September 12 about the risk for rare liver injury with fezolinetant, but the early signals that had been seen in fezolinetant data were not seen in these elinzanetant data.
The OASIS 1 and 2 trials enrolled postmenopausal women, aged 40-65 years, who had at least 50 moderate to severe vasomotor occurrences per week.
“A moderate hot flash is a hot flash that is also associated with sweating, and a severe hot flash is a moderate hot flash that stops a woman in her tracks,” Dr. Simon said. “Namely, it’s severe enough with sweating and central nervous system effects that she is interrupted in whatever it is that she’s doing at the time.”
Exclusion criteria for the trials included a history of arrhythmias, heart block, or QT prolongation; abnormal lab results; history of malignancy within the past 5 years; uncontrolled or treatment-resistant hypertension, hypothyroidism, or hyperthyroidism; unexplained postmenopausal bleeding; clinically relevant abnormal mammogram findings; or disordered proliferative endometrium, endometrial hyperplasia, polyp, or endometrial cancer.
The predominantly White (80%) women were an average 54 years old, with an average body mass index (BMI) of 27.8, and were an average 3.5 years from their last period. For the first 12 weeks of the trials, 399 women were assigned to receive 120 mg once daily of oral elinzanetant and 397 were assigned to once daily placebo. Then the women taking placebo switched to elinzanetant for the final 14 weeks of the study.
The endpoints included mean change in frequency and severity of vasomotor symptoms at weeks 1, 4, and 12 as well as change in sleep disturbance and quality of life at week 12. Sleep was assessed with the Patient-Reported Outcomes Measurement Information System Sleep Disturbance–Short Form score, which ranges from 28.9 to 76.5, with a higher number denoting greater sleep disturbance. The Menopause-Specific Quality-of-Life score ranges from 1 to 8, with a higher score indicating poorer quality of life.
Daily frequency of vasomotor symptoms was 14 per day at baseline in the elinzanetant group, decreasing by 4.8 per day at week 1, 8 per day at week 4, and 9.4 per day at week 12. In the placebo group, women had an average 15.2 occurrences per day at baseline, which decreased by 3.2 at week 1, 5.2 at week 4, and 6.4 at week 12. Comparing the groups at 12 weeks, those receiving elinzanetant had 3.2 fewer daily vasomotor symptoms than those receiving placebo (P < .0001).
The severity of vasomotor symptoms also improved more in the elinzanetant group than in the placebo group over 12 weeks, after which severity improved further in those who switched from placebo to elinzanetant (P < .0001).
Sleep disturbance scores, starting at a mean 61.5 in the elinzanetant group and 60.5 in the placebo group, fell 10.7 points in the elinzanetant group and 5.3 points in the placebo group at 12 weeks, for a difference of 4.9 points (P < .0001). Sleep then further improved in those who switched from placebo to elinzanetant. Quality-of-life scores improved 1.37 points (from 4.52 at baseline) in the elinzanetant group and 0.96 points (from 4.49 at baseline) in the placebo group, for a mean difference at 12 weeks of 0.36 (P < .0001).
Though no head-to-head data exist comparing elinzanetant and fezolinetant, Dr. Simon told this news organization the side effects with fezolinetant “tend to be gastrointestinal, whereas the side effects for elinzanetant tend to be central nervous system,” such as drowsiness and lethargy.
The women who are the best candidates for elinzanetant, Dr. Pinkerton told this news organization, include those who have had an estrogen-sensitive cancer, such as breast or endometrial cancer, or who have fear of it, a family history, or are otherwise high risk. Other ideal candidates include those with a history of venous thromboembolism, people who have migraine with aura (due to concerns about increased risk for stroke), and those who have endometriosis or large fibroids.
“Then the last group might be women who took hormone therapy in their 50s and want to continue, but they’re trying to go off, and they have a recurrence of their hot flashes or night sweats or sleep issues,” Dr. Pinkerton said. “This might be a great group to switch over.”
OASIS 3 assessed the drug for 1 year and “supported the results of OASIS 1 and 2, demonstrating efficacy over a longer study duration and in a population with a vasomotor symptom profile representative of that seen in clinical practice,” Nick Panay, BSc, MBBS, director of the Menopause & PMS Centre at Queen Charlotte’s Hospital & Imperial College London, London, England, and his colleague reported.
Among 628 postmenopausal women aged 40-65, the predominantly White (78.5%) women were an average 54 years old, with an average BMI of 27.6, and were an average 5 years past their last period. Half received 120 mg elinzanetant and half received a placebo for 52 weeks.
At 12 weeks, the women receiving elinzanetant reported an average 1.6 moderate to severe vasomotor symptoms per day, down from 6.7 at baseline. Daily average symptoms in the placebo group fell from 6.8 at baseline to 3.4 at 12 weeks, for a difference of 1.6 fewer occurrences per day in the elinzanetant group (P < .0001).
Sleep disturbances also improved, falling 9.4 points from a baseline 57.4 in the elinzanetant group and 5.7 points from a baseline 58 in the placebo group. Quality-of-life scores improved from 4.1 to 2.8 (−1.3 change) in the elinzanetant group and from 4.4 to 3.3 (−1.1 change) in the placebo group.
In addition to looking at treatment-emergent adverse events, the safety assessments also included endometrial biopsies; bone mineral density in the femoral neck, hip, and lumbar spine; weight; and labs. Adverse events related to the study drug occurred in 30.4% of those in the elinzanetant group and 14.6% of those in the placebo group. The most commonly reported adverse events were headache (9.6% elinzanetant vs 7% placebo), fatigue (7% vs 10.2%), and sleepiness (5.1% vs 1.3%). A higher proportion of women taking elinzanetant (12.5%) than those taking placebo (4.1%) discontinued the study.
No serious adverse events deemed to be treatment-related occurred in either group, and no endometrial hyperplasia or malignant neoplasm occurred in either group. Bone mineral density changes in both groups were within the expected range for the women’s age, and their weight remained stable over the 52 weeks.
Six women taking elinzanetant and four taking placebo met predefined criteria for close liver observation, but none showed hepatotoxicity or evidence of possible drug-induced liver injury.
The research was funded by Bayer. Dr. Pinkerton has run a trial funded by Bayer and is a consultant for Bayer and Pfizer. Dr. Shufelt had no disclosures.

Then the women taking placebo switched to elinzanetant for the final 14 weeks of the study.
The endpoints included mean change in frequency and severity of vasomotor symptoms at weeks 1, 4, and 12 as well as change in sleep disturbance and quality of life at week 12. Sleep was assessed with the Patient-Reported Outcomes Measurement Information System Sleep Disturbance–Short Form score, which ranges from 28.9 to 76.5, with a higher number denoting greater sleep disturbance. The Menopause-Specific Quality-of-Life score ranges from 1 to 8, with a higher score indicating poorer quality of life.
Daily frequency of vasomotor symptoms was 14 per day at baseline in the elinzanetant group, decreasing by 4.8 per day at week 1, 8 per day at week 4, and 9.4 per day at week 12. In the placebo group, women had an average 15.2 occurrences per day at baseline, which decreased by 3.2 at week 1, 5.2 at week 4, and 6.4 at week 12. Comparing the groups at 12 weeks, those receiving elinzanetant had 3.2 fewer daily vasomotor symptoms than those receiving placebo (P < .0001).
The severity of vasomotor symptoms also improved more in the elinzanetant group than in the placebo group over 12 weeks, after which severity improved further in those who switched from placebo to elinzanetant (P < .0001).
Sleep disturbance scores, starting at a mean 61.5 in the elinzanetant group and 60.5 in the placebo group, fell 10.7 points in the elinzanetant group and 5.3 points in the placebo group at 12 weeks, for a difference of 4.9 points (P < .0001). Sleep then further improved in those who switched from placebo to elinzanetant. Quality-of-life scores improved 1.37 points (from 4.52 at baseline) in the elinzanetant group and 0.96 points (from 4.49 at baseline) in the placebo group, for a mean difference at 12 weeks of 0.36 (P < .0001).
Though no head-to-head data exist comparing elinzanetant and fezolinetant, Dr. Simon told this news organization the side effects with fezolinetant “tend to be gastrointestinal, whereas the side effects for elinzanetant tend to be central nervous system,” such as drowsiness and lethargy.
The women who are the best candidates for elinzanetant, Dr. Pinkerton told this news organization, include those who have had an estrogen-sensitive cancer, such as breast or endometrial cancer, or who have fear of it, a family history, or are otherwise high risk. Other ideal candidates include those with a history of venous thromboembolism, people who have migraine with aura (due to concerns about increased risk for stroke), and those who have endometriosis or large fibroids.
“Then the last group might be women who took hormone therapy in their 50s and want to continue, but they’re trying to go off, and they have a recurrence of their hot flashes or night sweats or sleep issues,” Dr. Pinkerton said. “This might be a great group to switch over.”
OASIS 3 assessed the drug for 1 year and “supported the results of OASIS 1 and 2, demonstrating efficacy over a longer study duration and in a population with a vasomotor symptom profile representative of that seen in clinical practice,” Nick Panay, BSc, MBBS, director of the Menopause & PMS Centre at Queen Charlotte’s Hospital & Imperial College London, London, England, and his colleague reported.
Among 628 postmenopausal women aged 40-65, the predominantly White (78.5%) women were an average 54 years old, with an average BMI of 27.6, and were an average 5 years past their last period. Half received 120 mg elinzanetant and half received a placebo for 52 weeks.
At 12 weeks, the women receiving elinzanetant reported an average 1.6 moderate to severe vasomotor symptoms per day, down from 6.7 at baseline. Daily average symptoms in the placebo group fell from 6.8 at baseline to 3.4 at 12 weeks, for a difference of 1.6 fewer occurrences per day in the elinzanetant group (P < .0001).
Sleep disturbances also improved, falling 9.4 points from a baseline 57.4 in the elinzanetant group and 5.7 points from a baseline 58 in the placebo group. Quality-of-life scores improved from 4.1 to 2.8 (−1.3 change) in the elinzanetant group and from 4.4 to 3.3 (−1.1 change) in the placebo group.
In addition to looking at treatment-emergent adverse events, the safety assessments also included endometrial biopsies; bone mineral density in the femoral neck, hip, and lumbar spine; weight; and labs. Adverse events related to the study drug occurred in 30.4% of those in the elinzanetant group and 14.6% of those in the placebo group. The most commonly reported adverse events were headache (9.6% elinzanetant vs 7% placebo), fatigue (7% vs 10.2%), and sleepiness (5.1% vs 1.3%). A higher proportion of women taking elinzanetant (12.5%) than those taking placebo (4.1%) discontinued the study.
No serious adverse events deemed to be treatment-related occurred in either group, and no endometrial hyperplasia or malignant neoplasm occurred in either group. Bone mineral density changes in both groups were within the expected range for the women’s age, and their weight remained stable over the 52 weeks.
Six women taking elinzanetant and four taking placebo met predefined criteria for close liver observation, but none showed hepatotoxicity or evidence of possible drug-induced liver injury.

No Signal of Benefit for Simvastatin in Progressive MS
COPENHAGEN — There were high hopes that simvastatin, a well-tolerated lipid-lowering therapy, would reduce disability progression in patients with nonflaring secondary progressive multiple sclerosis (SPMS), but a definitive multicenter double-blind randomized trial found no benefit at all.
“There was no effect on the primary outcome of confirmed progression or on any of the secondary outcomes,” reported Jeremy Chataway, MD, PhD, consultant neurologist, National Hospital for Neurology and Neurosurgery, University College of London, England.
For the primary outcome of progression on the Expanded Disability Status Scale (EDSS), the nonsignificant hazard ratio (HR) was, in fact, in favor of placebo (HR, 1.13; P = .26) over 45 months of follow-up and 365 progression events.
No Meaningful Difference Between Study Arms
“There were wide confidence intervals [95% CI, 0.91-1.39], so, really, there were no differences between the two arms,” reported Dr. Chataway, who presented the simvastatin trial, called MS-STAT2, during the late-breaker session of the 2024 ECTRIMS annual meeting.
Over a period of more than 20 years, a series of experimental and clinical studies have indicated that simvastatin and other CoA reductase inhibitors have anti-inflammatory and neuroprotective effects. These studies were the basis for the first MED-STAT study, which was a placebo-controlled randomized trial published in 2014.
Although this study did not have a clinical endpoint, it associated simvastatin with a 43% reduction (P = .003) in the annualized rate of brain atrophy, which has been widely accepted as a surrogate measure of MS progression.
In MS-STAT2, 964 patients were available for the intention-to-treat analysis. An established diagnosis of SPMS, an age of 25-65, and an EDSS score of 4.0-6.5 were among the inclusion criteria. Patients were required to be relapse-free for at least 3 months prior to study entry.
Importantly, patients were excluded if they were taking statin-lowering therapies or were candidates for these therapies due to the presence of cardiovascular disease. They were also excluded from entering the trial if taking immunosuppressants, such as methotrexate or azathioprine, or had exposure to monoclonal antibodies employed in the treatment of MS, such as natalizumab and alemtuzumab, in the prior 12 months.
Randomized to 80 mg of simvastatin (40 mg in the first month followed by rapid upward titration) or placebo in a 1:1 fashion, patients remained on their assigned therapy for 3 years in the absence of progression. At the end of this time, patients who remained progression-free could continue for up to 45 months while still blinded to treatment assignment.
Even though a large proportion of patients who were eligible to remain in the study for the full 45 months did so, the retention did not reflect clinical improvement.
Indeed, the secondary endpoints also produced no signal of benefit. On a composite secondary endpoint of EDSS, ambulation in the form of the 25-foot walk, and upper extremity function in the form of the 9-hole peg test (9-HPT), the numerical odds ratio (OR) went in the wrong direction for simvastatin although the difference was not significant (OR, 1.17; P = .26).
Annualized Relapse Rate Numerically Higher on Simvastatin
The annualized relapse rate, another secondary endpoint, was low in both arms of the study at 0.05 relapses/year for placebo and 0.7 relapses/year for simvastatin. Again, this result, although numerically unfavorable for simvastatin did not reach statistical significance (OR, 1.43; P = .04).
Simvastatin had a placebo-like safety profile. The single case of rhabdomyolysis in the simvastatin arm, which occurred early after randomization, resolved. Otherwise, simvastatin was well tolerated.
Conducted before and through the period of the COVID-19 pandemic, the number of progression events tripled in the year after the COVID-19 pandemic started relative to the prior year. At the end of the pandemic, progression events returned to a level similar to that before its onset. However, although Dr. Chataway noted this was an interesting example of comorbidities exacerbating MS, he emphasized that this increase was similar in the simvastatin and placebo arms.
There are more analyses to come, including patient-reported outcomes, biomarker analyses, and further comparisons of change in MRIs, but Dr. Chataway acknowledged that the study provided no support for the underlying hypothesis.
Several experts commenting after the study was presented, including Ludwig Kappos, MD, PhD, Chair of Neurology at the University Hospital, Basel, Switzerland, agreed.
“Unfortunately, these results are quite disappointing,” he said. When asked if there is any rationale for further pursuing studies of simvastatin for the treatment of SPMS, he said no.
“These data are quite convincing that there is no benefit. I do not see where you could go from here,” Dr. Kappos said in an interview.
Dr. Chataway, asked the same question, reiterated that there are a number of preplanned analyses that will be completed, but he does not foresee further studies with simvastatin for the indication studied in MS-STAT-2 trial.
However, he also emphasized strongly that simvastatin or any other lipid-lowering therapy should not be withheld from MS patients that need these drugs for a cardiovascular indication.
“We saw no benefit seen from simvastatin for patients with stable SPMS, but these drugs were well tolerated and they can be life-saving therapies for patients with increased cardiovascular risk,” Dr. Chataway said.
Dr, Chataway reported financial relationships with Biogen, Genzyme, Ionis, Lucid, Merck NerveGen, Novartis, Roche, and Sanofi. Dr. Kappos reports financial relationships with more than 20 pharmaceutical companies. The MS-STAT2 trial received no funding from industry.

Epilepsy Drug May Reduce Symptoms of OSA
An epilepsy drug sold in Europe as Ospolot and also known as sulthiame showed promise in reducing sleep disordered breathing and other symptoms of obstructive sleep apnea (OSA), based on data from nearly 300 individuals presented in a late-breaking study at the annual congress of the European Respiratory Society.
“Current therapies are mechanical and based on the notion of an airway splint,” presenting author Jan Hedner, MD, professor of respiratory medicine at Sahlgrenska University Hospital and the University of Gothenburg, both in Sweden, said in an interview. “In other words, applying an airflow at elevated pressure [continuous positive airway pressure] or advancing the jaw with a dental device. Adherence to this type of therapy is limited. In the case of continuous positive airway pressure [CPAP], it is < 50% after 3-4 years of therapy.” Therefore, there is a need for a better-tolerated therapy, such as a drug, and possibly a combination of mechanical and pharmaceutical therapies.
The use of medication has emerged as a viable option for OSA, with a high rate of compliance and acceptable safety profile, Dr. Hedner said in his presentation.
“Modified carbonic anhydrase activity may be a pathophysiological mechanism in OSA,” said Dr. Hedner. Sulthiame, a carbonic anhydrase inhibitor, showed safety and effectiveness for improving OSA in a previous phase 2b trial.
In the current study, the researchers sought to determine the most effective dose of sulthiame for patients with OSA. They randomized 298 adults with OSA who could not accept or tolerate oral splints or CPAP to 100 mg, 200 mg, or 300 mg of sulthiame daily (74, 74, and 75 patients, respectively) or placebo (75 patients).
The mean age of the patients was 56 years, 26.2% were women, and the average apnea-hypopnea index (AHI3a) at baseline was 29 n/h. Patients were treated at centers in Spain, France, Belgium, Germany, and the Czech Republic. Baseline demographics and clinical characteristics were similar among the treatment groups.
The primary endpoint was the change in AHI3a from baseline to 15 weeks, and significant changes occurred in patients who received the 100-mg, 200-mg, and 300-mg doses, with decreases of 17.8%, 34.8%, and 39.9%, respectively.
Dr. Hedner said in his presentation.
Notably, in a post hoc analysis, apnea improved by 47.1% at a 300-mg dose when the AHI4 measure (apnea/hypopnea with ≥ 4% O2 desaturation) was used in a placebo-adjusted dose-dependent reduction, the researchers wrote. The changes in AHI4 from baseline in this analysis also were significant for 200 mg and 100 mg doses (36.8% and 26.2%, respectively).
Patients underwent polysomnography at baseline and at weeks 4 and 12.
Mean overnight oxygen saturation also improved significantly from baseline with doses of 200 mg and 300 mg, compared with placebo (P < .0001 for both).
In addition, scores on the Epworth Sleepiness Scale (ESS) improved from baseline to week 15 in all dosage groups, and the subgroup of patients with ESS scores of ≥ 11 at baseline showed even greater improvement in ESS, Dr. Hedner said in his presentation.
Total arousal index and sleep quality also improved from baseline compared with placebo, and no clinically relevant reduction in REM sleep was noted, Dr. Hedner added.
Treatment-emergent adverse events were in line with the known safety profile of sulthiame and included paresthesia, headache, fatigue, and nausea; these were mainly moderate and dose-dependent, with no evidence of cardiovascular safety issues, he said.
Although the study results were not surprising given previous research, the investigators were pleased with the potency of the therapy. “We are also happy about potential added values such as a blood pressure lowering effect, which is beneficial in this group of patients; however, we need to further study these mechanisms in detail,” Dr. Hedner noted.
The study findings were limited by the relatively small scale, and larger studies on long-term efficacy and tolerability are also needed, he said.
“The current study was a dose-finding study, and we now have useful information on most suitable dose,” he said.
However, the results support sulthiame as an effective, well-tolerated, and promising novel candidate for drug therapy in patients with OSA, worthy of phase 3 studies, Dr. Hedner said.
Oral Option Could Be Game-Changer, But Not Yet
The gold standard of treatment for OSA is a CPAP machine, but the effectiveness is limited by patient tolerance, Q. Afifa Shamim-Uzzaman, MD, an associate professor and a sleep medicine specialist at the University of Michigan, Ann Arbor, said in an interview.
“Presently, there are no effective pharmacological treatments for OSA — having a pill that treats OSA would be a total game changer and huge advance for the treatment of OSA and the field of sleep medicine,” said Dr. Shamim-Uzzaman, who was not involved in the study. “More patients may be able to obtain treatment for OSA and thereby reduce the potential complications of untreated OSA.
“Carbonic anhydrase inhibitors such as acetazolamide and sulthiame have been studied with limited success for the treatment of other forms of sleep disordered breathing such as central sleep apnea [CSA] but have shown less efficacy for OSA and are presently not recommended in the treatment of OSA by the American Academy of Sleep Medicine,” Dr. Shamim-Uzzaman said.
Recently, emerging evidence about different phenotypes of OSA suggests that nonanatomic features (such as high loop gain) may play a role in patients with OSA, not only in those with CSA, she said. Whether carbonic anhydrase inhibitors could play a greater role in treating sleep apnea in patients with predominantly nonanatomic pathophysiologic traits remains to be seen.
The sulthiame data are promising, but more research is needed, Dr. Shamim-Uzzaman said. Although patients in the highest dose group showed a reduction in AHI of nearly 40%, they still would have moderate OSA, and the OSA did not appear to decrease to a normal range in any of the treatment groups.
“More research is needed to identify which types of patients would be responders to this form of therapy, to understand if these effects are maintained long term (beyond 15 weeks), to evaluate patient-centered outcomes, especially in different sleep apnea subgroups (such as phenotypes with high loop gain vs those without), and to assess interactions with other therapies,” she said.
The study was supported by manufacturer Desitin. Dr. Hedner disclosed serving as a consultant to AstraZeneca, Bayer, CereusScience, Jazz Pharmaceuticals, MSD, Weinmann, Desitin, SomnoMed, and Itamar Medical; serving on the speakers’ bureau for Almirall, AstraZeneca, Jazz Pharmaceuticals, ResMed, Philips Respironics, and Weinmann; and receiving grants or research support from Bayer, ResMed, Philips Respironics, and SomnoMed. He also disclosed shared ownership of intellectual property related to sleep apnea therapy. Dr. Shamim-Uzzaman had no financial conflicts to disclose.

In addition, scores on the Epworth Sleepiness Scale (ESS) improved from baseline to week 15 in all dosage groups, and the subgroup of patients with ESS scores of ≥ 11 at baseline showed even greater improvement in ESS, Dr. Hedner said in his presentation.
Total arousal index and sleep quality also improved from baseline compared with placebo, and no clinically relevant reduction in REM sleep was noted, Dr. Hedner added.
Treatment-emergent adverse events were in line with the known safety profile of sulthiame and included paresthesia, headache, fatigue, and nausea; these were mainly moderate and dose-dependent, with no evidence of cardiovascular safety issues, he said.
Although the study results were not surprising given previous research, the investigators were pleased with the potency of the therapy. “We are also happy about potential added values such as a blood pressure lowering effect, which is beneficial in this group of patients; however, we need to further study these mechanisms in detail,” Dr. Hedner noted.
The study findings were limited by the relatively small scale, and larger studies on long-term efficacy and tolerability are also needed, he said.
“The current study was a dose-finding study, and we now have useful information on most suitable dose,” he said.
However, the results support sulthiame as an effective, well-tolerated, and promising novel candidate for drug therapy in patients with OSA, worthy of phase 3 studies, Dr. Hedner said.
Oral Option Could Be Game-Changer, But Not Yet
The gold standard of treatment for OSA is a CPAP machine, but the effectiveness is limited by patient tolerance, Q. Afifa Shamim-Uzzaman, MD, an associate professor and a sleep medicine specialist at the University of Michigan, Ann Arbor, said in an interview.
“Presently, there are no effective pharmacological treatments for OSA — having a pill that treats OSA would be a total game changer and huge advance for the treatment of OSA and the field of sleep medicine,” said Dr. Shamim-Uzzaman, who was not involved in the study. “More patients may be able to obtain treatment for OSA and thereby reduce the potential complications of untreated OSA.
“Carbonic anhydrase inhibitors such as acetazolamide and sulthiame have been studied with limited success for the treatment of other forms of sleep disordered breathing such as central sleep apnea [CSA] but have shown less efficacy for OSA and are presently not recommended in the treatment of OSA by the American Academy of Sleep Medicine,” Dr. Shamim-Uzzaman said.
Recently, emerging evidence about different phenotypes of OSA suggests that nonanatomic features (such as high loop gain) may play a role in patients with OSA, not only in those with CSA, she said. Whether carbonic anhydrase inhibitors could play a greater role in treating sleep apnea in patients with predominantly nonanatomic pathophysiologic traits remains to be seen.
The sulthiame data are promising, but more research is needed, Dr. Shamim-Uzzaman said. Although patients in the highest dose group showed a reduction in AHI of nearly 40%, they still would have moderate OSA, and the OSA did not appear to decrease to a normal range in any of the treatment groups.
“More research is needed to identify which types of patients would be responders to this form of therapy, to understand if these effects are maintained long term (beyond 15 weeks), to evaluate patient-centered outcomes, especially in different sleep apnea subgroups (such as phenotypes with high loop gain vs those without), and to assess interactions with other therapies,” she said.
The study was supported by manufacturer Desitin. Dr. Hedner disclosed serving as a consultant to AstraZeneca, Bayer, CereusScience, Jazz Pharmaceuticals, MSD, Weinmann, Desitin, SomnoMed, and Itamar Medical; serving on the speakers’ bureau for Almirall, AstraZeneca, Jazz Pharmaceuticals, ResMed, Philips Respironics, and Weinmann; and receiving grants or research support from Bayer, ResMed, Philips Respironics, and SomnoMed. He also disclosed shared ownership of intellectual property related to sleep apnea therapy. Dr. Shamim-Uzzaman had no financial conflicts to disclose.

An epilepsy drug sold in Europe as Ospolot and also known as sulthiame showed promise in reducing sleep disordered breathing and other symptoms of obstructive sleep apnea (OSA), based on data from nearly 300 individuals presented in a late-breaking study at the annual congress of the European Respiratory Society.
“Current therapies are mechanical and based on the notion of an airway splint,” presenting author Jan Hedner, MD, professor of respiratory medicine at Sahlgrenska University Hospital and the University of Gothenburg, both in Sweden, said in an interview. “In other words, applying an airflow at elevated pressure [continuous positive airway pressure] or advancing the jaw with a dental device. Adherence to this type of therapy is limited. In the case of continuous positive airway pressure [CPAP], it is < 50% after 3-4 years of therapy.” Therefore, there is a need for a better-tolerated therapy, such as a drug, and possibly a combination of mechanical and pharmaceutical therapies.
The use of medication has emerged as a viable option for OSA, with a high rate of compliance and acceptable safety profile, Dr. Hedner said in his presentation.
“Modified carbonic anhydrase activity may be a pathophysiological mechanism in OSA,” said Dr. Hedner. Sulthiame, a carbonic anhydrase inhibitor, showed safety and effectiveness for improving OSA in a previous phase 2b trial.
In the current study, the researchers sought to determine the most effective dose of sulthiame for patients with OSA. They randomized 298 adults with OSA who could not accept or tolerate oral splints or CPAP to 100 mg, 200 mg, or 300 mg of sulthiame daily (74, 74, and 75 patients, respectively) or placebo (75 patients).
The mean age of the patients was 56 years, 26.2% were women, and the average apnea-hypopnea index (AHI3a) at baseline was 29 n/h. Patients were treated at centers in Spain, France, Belgium, Germany, and the Czech Republic. Baseline demographics and clinical characteristics were similar among the treatment groups.
The primary endpoint was the change in AHI3a from baseline to 15 weeks, and significant changes occurred in patients who received the 100-mg, 200-mg, and 300-mg doses, with decreases of 17.8%, 34.8%, and 39.9%, respectively.
Dr. Hedner said in his presentation.
Notably, in a post hoc analysis, apnea improved by 47.1% at a 300-mg dose when the AHI4 measure (apnea/hypopnea with ≥ 4% O2 desaturation) was used in a placebo-adjusted dose-dependent reduction, the researchers wrote. The changes in AHI4 from baseline in this analysis also were significant for 200 mg and 100 mg doses (36.8% and 26.2%, respectively).
Patients underwent polysomnography at baseline and at weeks 4 and 12.
Mean overnight oxygen saturation also improved significantly from baseline with doses of 200 mg and 300 mg, compared with placebo (P < .0001 for both).
In addition, scores on the Epworth Sleepiness Scale (ESS) improved from baseline to week 15 in all dosage groups, and the subgroup of patients with ESS scores of ≥ 11 at baseline showed even greater improvement in ESS, Dr. Hedner said in his presentation.

New Options for Treating Atopic Dermatitis Available, and in Development
HUNTINGTON BEACH, CALIFORNIA — If the number of recent drug approvals for atopic dermatitis (AD) is overwhelming, the future is unlikely to be any less challenging: According to the National Eczema Association, the current pipeline for AD includes 39 injectable medications, 21 oral agents, and 49 topicals, some with novel targets, like human umbilical cord blood derived stem cells.
“It’s amazing how many drugs are coming out for AD,” Robert Sidbury, MD, MPH, said at the annual meeting of the Pacific Dermatologic Association (PDA). and is approved in Europe for the treatment of moderate to severe AD in patients aged ≥ 12 years. (On September 13, after the PDA meeting, lebrikizumab was approved by the Food and Drug Administration [FDA] for treatment of moderate to severe AD in adults and adolescents aged ≥ 12 years.)
In two identical phase 3 trials known as ADvocate 1 and ADvocate 2, researchers randomly assigned 851 patients with moderate to severe AD in a 2:1 ratio to receive either lebrikizumab at a dose of 250 mg (loading dose of 500 mg at baseline and week 2) or placebo, administered subcutaneously every 2 weeks, through week 16. The primary outcome was an Investigator’s Global Assessment (IGA) score of 0 or 1, indicating clear or almost clear skin. The researchers reported that an IGA score of 0 or 1 was achieved by 43.1% of patients in the lebrikizumab arm compared with 12.7% of those in the placebo arm.
“Those are good numbers,” said Dr. Sidbury, who was not involved with the study. Conjunctivitis occurred more often in those who received lebrikizumab compared with those who received placebo (7.4% vs 2.8%, respectively), “which is not surprising because it is an IL-13 agent,” he said.
In a subsequent study presented during the Revolutionizing Atopic Dermatitis meeting in the fall of 2023, researchers presented data on Eczema Severity and Area Index (EASI)-90 responses in the ADvocate trial participants, showing EASI-90 responses were sustained up to 38 weeks after lebrikizumab withdrawal, while serum concentrations were negligible. They found that between week 14 and week 32, approximately five serum concentration half-lives of the medication had elapsed since patients randomized to the withdrawal arm received their last dose of lebrikizumab, extending to approximately 11 half-lives by week 52. “That durability of response with next to no blood levels of drug in many of the study participants is interesting,” said Dr. Sidbury, who cochairs the current iteration of the American Academy of Dermatology Atopic Dermatitis Guidelines.
Nemolizumab is a neuroimmune response modulator that inhibits the IL-31 receptor and is approved in Japan for the treatment of itch associated with AD in patients aged ≥ 13 years. Results from two identical phase 3, randomized, controlled trials known as ARCADIA 1 and ARCADIA 2 found that 36% of patients in ARCADIA 1 and 38% in ARCADIA 2 achieved clear skin, compared with 25% and 26% of patients in the placebo group, respectively. (Nemolizumab was recently approved by the FDA for treating prurigo nodularis and is under FDA review for AD.)
In terms of safety, Dr. Sidbury, who is a member of the steering committee for the ARCADIA trials, said that nemolizumab has been “generally well tolerated;” with 1%-3% of study participants experiencing at least one serious treatment-emergent adverse event that included asthma exacerbation, facial edema, and peripheral edema. “The latest data are reassuring but we are watching these safety concerns carefully,” he said.
Dr. Sidbury disclosed that he is an investigator for Regeneron, Pfizer, Galderma, UCB, and Castle; a consultant for Lilly, Leo, Arcutis, and Dermavant; and a member of the speaker’s bureau for Beiersdorf.

Disability Reduction Is a Twist in Negative BTKi RRMS Trial
COPENHAGEN — In two phase 3 head-to-head comparing the Bruton tyrosine kinase inhibitor (BTKi) tolebrutinib to the immunomodulatory teriflunomide for relapsing-remitting multiple sclerosis (RRMS), there was no advantage on the primary endpoint of relapse, but the greater protection against disability, a secondary endpoint, might change thinking about BTKis as a potential MS therapy.
For annualized relapse rate (ARR), which is the basis on which these two drugs were compared, “there was no difference between tolebrutinib and teriflunomide,” reported Jiwon Oh, MD, Medical Director, Barlo Multiple Sclerosis Program, St. Michael’s Hospital, University of Toronto, Canada.
In the similar GEMINI 1 and 2 trials, the ARRs were nearly identical in the first, (0.13 and 0.12), and completely identical in the second (0.11) for tolebrutinib and teriflunomide, respectively.
Although Negative, GEMINI Trials Offer Intriguing Data
These data rule out the study hypothesis that a BTKi offers greater protection against relapse than a commonly used immunomodulator, but Dr. Oh suggested the study is still potentially relevant to MS research.
“There is hope,” Dr. Oh said, when reporting the findings of the GEMINI I and II trials during the latebreaker session at the 2024 ECTRIMS annual meeting. Ultimately, a substantial part of this hope was derived from the consistency of the GEMINI data with the placebo-controlled HERCULES trial of tolebrutinib presented immediately afterwards, but the disparity between the primary and secondary outcomes of GEMINI are, by themselves, relevant, suggesting that targets of treatment change as MS progresses from an acute to a chronic inflammatory process.
BTKi Associated With Reduced Disability
At 3 months, the rate of confirmed disability worsening (CDW) in the pooled GEMINI trials was 18.5% and 14.7% for tolebrutinib and teriflunomide, respectively, producing at 27% reduction in hazard ratio (HR) for this outcome (HR 0.73; P = .0018). At 6 months, the protection against disability (13.2% vs. 9.9%) persisted for tolebrutinib relative to teriflunomide (HR 0.71; P = .023).*
For the outcome of a confirmed disability improvement at 6 months, the higher rate in the tolebrutinib arm did not reach statistical significance (12.8% vs. 12.0%), but it did suggest a favorable trend (HR 1.22; P = .17).
While Dr. Oh acknowledged that secondary outcomes can only be considered hypothesis generating when the primary outcome is negative, she said these outcomes provide intriguing support for the potential of this BTKi drug to inhibit “smoldering inflammation.” Even if tolebrutinib was no more effective than teriflunomide against the acute inflammation that drives relapse, the GEMINI trials data support greater inhibition of the chronic inflammation implicated in progression in the absence of flares.
On MRI, the annualized rate of new and enlarging T2 lesions, although numerically higher in the tolebrutinib group, did not differ significantly in either GEMINI 1 (5.6 vs. 5.2; P = .46) or GEMINI 2 (5.1 vs. 4.4; P = .24). The least mean square difference in brain volume at end of study relative to 6 months into the study was 0.2% less in the tolebrutinib arm than the teriflunomide arm (P = .0002) in GEMINI 1, but the 0.04 numerical advantage for tolebrutinib did not reach statistical significance in GEMINI 2 (P = .43).
Of the 974 patients randomized in GEMINI 1 and 899 randomized in GEMINI 2, about 85% completed the 3-year trial. Almost all had RRMS (99%) rather than progressing MS. The median age was approximately 36 years, the baseline EDSS score was approximately 1.2, and the median time since diagnosis was about 6.5 years. The mean number of relapses in the prior year was approximately 0.6.
In GEMINI, the secondary outcomes foreshadowed the positive findings in the phase 3 HERCULES trial that came immediately after Dr. Oh’s GEMINI trials presentation. The HERCULES trial associated tolebrutinib with a 31% reduction in the risk of confirmed disability progression (CDW) relative to placebo in patients with non-relapsing secondary progressive MS (nrSPMS).
In HERCULES, 1172 patients with nrSPMS were randomized in a 2:1 fashion to tolebrutinib or placebo. For the primary endpoint of CDW at 6 months, tolebrutinib demonstrated a major and highly significant reduction in this primary endpoint (HR 0.69; P = .00026).
BTKi Disability Protection Supported By Progressive MS Trial
“This is the first trial to show significant slowing of disability in people with nrSPMS,” reported the principal investigator Robert J. Fox, MD, Vice Chair of the Neurological Institute at Cleveland Clinic, Cleveland, Ohio.
For disability improvement at 6 months, tolebrutinib was associated with a nearly 2-fold improvement (HR 1.88; P = .021). According to both Dr. Oh and Dr. Fox the results of these two major phase 3 tolebrutinib studies support the principle that the BTKi, which was shown to offer inhibition of relapse comparable to teriflunomide in the GEMINI trials, offers a greater inhibition of chronic inflammation.
“These results are consistent with the hypothesis that acute focal inflammation and smoldering neuroinflammation are two distinct biological processes,” Dr. Oh said.
Dr. Fox said that the HERCULES results will be submitted to regulatory authorities with the goal of securing an indication for tolebrutinib for nrSPMS.
Both Dr. Oh and Dr. Fox suggested these results are likely to reorient thinking about the pathophysiology of MS progression and how different processes can be targeted in the future. Other experts agreed.
“I think we are starting to look at different endpoints than ARR, particularly at those that might better reflect progression in later stages of MS and that are independent of ARR,” said Dalia Rotstein, MD, MS researcher and an assistant professor of neurology, University of Toronto, Canada.
A moderator of the ECTRIMS latebreaker session, she suggested that the differences between outcomes of the GEMINI trials and HERCULES trials might have relevance to each other even if the GEMINI trials did not meet their primary endpoint.
Dr. Oh reported financial relationships with Amgen, Biogen, Eli Lilly, EMD Serono, Novartis, Roche, and Sanofi, which provided funding for the GEMINI trials. Dr. Fox reported financial relationships with more than 15 pharmaceutical companies, including Sanofi, which also provided funding for the HERCULES trial. Dr. Rotstein reported financial relationships with Alexion, Biogen, EMD Serono, Horizon, Novartis, Roche, Sanofi, and Touch IME.

In HERCULES, 1172 patients with nrSPMS were randomized in a 2:1 fashion to tolebrutinib or placebo. For the primary endpoint of CDW at 6 months, tolebrutinib demonstrated a major and highly significant reduction in this primary endpoint (HR 0.69; P = .00026).
BTKi Disability Protection Supported By Progressive MS Trial
“This is the first trial to show significant slowing of disability in people with nrSPMS,” reported the principal investigator Robert J. Fox, MD, Vice Chair of the Neurological Institute at Cleveland Clinic, Cleveland, Ohio.
For disability improvement at 6 months, tolebrutinib was associated with a nearly 2-fold improvement (HR 1.88; P = .021). According to both Dr. Oh and Dr. Fox the results of these two major phase 3 tolebrutinib studies support the principle that the BTKi, which was shown to offer inhibition of relapse comparable to teriflunomide in the GEMINI trials, offers a greater inhibition of chronic inflammation.
“These results are consistent with the hypothesis that acute focal inflammation and smoldering neuroinflammation are two distinct biological processes,” Dr. Oh said.
Dr. Fox said that the HERCULES results will be submitted to regulatory authorities with the goal of securing an indication for tolebrutinib for nrSPMS.
Both Dr. Oh and Dr. Fox suggested these results are likely to reorient thinking about the pathophysiology of MS progression and how different processes can be targeted in the future. Other experts agreed.
“I think we are starting to look at different endpoints than ARR, particularly at those that might better reflect progression in later stages of MS and that are independent of ARR,” said Dalia Rotstein, MD, MS researcher and an assistant professor of neurology, University of Toronto, Canada.
A moderator of the ECTRIMS latebreaker session, she suggested that the differences between outcomes of the GEMINI trials and HERCULES trials might have relevance to each other even if the GEMINI trials did not meet their primary endpoint.
Dr. Oh reported financial relationships with Amgen, Biogen, Eli Lilly, EMD Serono, Novartis, Roche, and Sanofi, which provided funding for the GEMINI trials. Dr. Fox reported financial relationships with more than 15 pharmaceutical companies, including Sanofi, which also provided funding for the HERCULES trial. Dr. Rotstein reported financial relationships with Alexion, Biogen, EMD Serono, Horizon, Novartis, Roche, Sanofi, and Touch IME.

COPENHAGEN — In two phase 3 head-to-head comparing the Bruton tyrosine kinase inhibitor (BTKi) tolebrutinib to the immunomodulatory teriflunomide for relapsing-remitting multiple sclerosis (RRMS), there was no advantage on the primary endpoint of relapse, but the greater protection against disability, a secondary endpoint, might change thinking about BTKis as a potential MS therapy.
For annualized relapse rate (ARR), which is the basis on which these two drugs were compared, “there was no difference between tolebrutinib and teriflunomide,” reported Jiwon Oh, MD, Medical Director, Barlo Multiple Sclerosis Program, St. Michael’s Hospital, University of Toronto, Canada.
In the similar GEMINI 1 and 2 trials, the ARRs were nearly identical in the first, (0.13 and 0.12), and completely identical in the second (0.11) for tolebrutinib and teriflunomide, respectively.
Although Negative, GEMINI Trials Offer Intriguing Data
These data rule out the study hypothesis that a BTKi offers greater protection against relapse than a commonly used immunomodulator, but Dr. Oh suggested the study is still potentially relevant to MS research.
“There is hope,” Dr. Oh said, when reporting the findings of the GEMINI I and II trials during the latebreaker session at the 2024 ECTRIMS annual meeting. Ultimately, a substantial part of this hope was derived from the consistency of the GEMINI data with the placebo-controlled HERCULES trial of tolebrutinib presented immediately afterwards, but the disparity between the primary and secondary outcomes of GEMINI are, by themselves, relevant, suggesting that targets of treatment change as MS progresses from an acute to a chronic inflammatory process.
BTKi Associated With Reduced Disability
At 3 months, the rate of confirmed disability worsening (CDW) in the pooled GEMINI trials was 18.5% and 14.7% for tolebrutinib and teriflunomide, respectively, producing at 27% reduction in hazard ratio (HR) for this outcome (HR 0.73; P = .0018). At 6 months, the protection against disability (13.2% vs. 9.9%) persisted for tolebrutinib relative to teriflunomide (HR 0.71; P = .023).*
For the outcome of a confirmed disability improvement at 6 months, the higher rate in the tolebrutinib arm did not reach statistical significance (12.8% vs. 12.0%), but it did suggest a favorable trend (HR 1.22; P = .17).
While Dr. Oh acknowledged that secondary outcomes can only be considered hypothesis generating when the primary outcome is negative, she said these outcomes provide intriguing support for the potential of this BTKi drug to inhibit “smoldering inflammation.” Even if tolebrutinib was no more effective than teriflunomide against the acute inflammation that drives relapse, the GEMINI trials data support greater inhibition of the chronic inflammation implicated in progression in the absence of flares.
On MRI, the annualized rate of new and enlarging T2 lesions, although numerically higher in the tolebrutinib group, did not differ significantly in either GEMINI 1 (5.6 vs. 5.2; P = .46) or GEMINI 2 (5.1 vs. 4.4; P = .24). The least mean square difference in brain volume at end of study relative to 6 months into the study was 0.2% less in the tolebrutinib arm than the teriflunomide arm (P = .0002) in GEMINI 1, but the 0.04 numerical advantage for tolebrutinib did not reach statistical significance in GEMINI 2 (P = .43).
Of the 974 patients randomized in GEMINI 1 and 899 randomized in GEMINI 2, about 85% completed the 3-year trial. Almost all had RRMS (99%) rather than progressing MS. The median age was approximately 36 years, the baseline EDSS score was approximately 1.2, and the median time since diagnosis was about 6.5 years. The mean number of relapses in the prior year was approximately 0.6.
In GEMINI, the secondary outcomes foreshadowed the positive findings in the phase 3 HERCULES trial that came immediately after Dr. Oh’s GEMINI trials presentation. The HERCULES trial associated tolebrutinib with a 31% reduction in the risk of confirmed disability progression (CDW) relative to placebo in patients with non-relapsing secondary progressive MS (nrSPMS).
In HERCULES, 1172 patients with nrSPMS were randomized in a 2:1 fashion to tolebrutinib or placebo. For the primary endpoint of CDW at 6 months, tolebrutinib demonstrated a major and highly significant reduction in this primary endpoint (HR 0.69; P = .00026).

Seborrheic Dermatitis in Black Patients: New Therapies Offer Hope
NEW YORK — not only in this group but also overall, now that there is an approved therapy with an array of alternatives and adjunctive medications, according to Shawn Kwatra, MD.
The list of therapies effective against SD, often employed in combination, is lengthy, but topical 0.3% roflumilast foam (Zoryve), approved by the Food and Drug Administration (FDA) late last year for treating SD, has a high rate of efficacy and should now be considered a first-line treatment option, according to Dr. Kwatra, professor and chair of the Department of Dermatology, University of Maryland School of Medicine, Baltimore.
New Approved Therapy Draws Attention to SD
Emphasizing that topical roflumilast does not necessarily replace the use of over-the-counter shampoos and emollients or a list of prescription drugs used off-label to control this condition, he said it is also important for another reason.
“It shines a light on this disease,” said Dr. Kwatra, speaking at the 2024 Skin of Color Update. While his comments were focused primarily on individuals with darker skin, his major take home messages were broadly relevant across skin types.
He acknowledged that for years he “had not given seborrheic dermatitis the respect that it deserves” even though this condition comes after only acne and eczema as chief complaints among Black individuals seeing a dermatologist. The estimated global incidence is 5%, according to Dr. Kwatra, but he considers this estimate of an often “forgotten disease” too low.
One reason is that many individuals self-treat with over-the-counter solutions and never bring the complaint to a clinician. Dr. Kwatra said that he now looks for it routinely and points it out to patients who have come to him for another reason.
In patients with darker skin, the signs of SD can differ. While scalp involvement is generally easy to identify across skin types, the inflammation and erythema, sebum production, scaling and itch, and Malassezia that accompanies and drives SD might be missed in a patient with darker skin without specifically looking for these signs.
Skin and Gut Microbiome Involvement Suspected
The underlying causes of SD are understood as an inflammatory process involving keratinocyte disruption and proliferation that ultimately impairs skin barrier function, causes water loss, and produces scale stemming from stratum corneum, but Dr. Kwatra said that there is increasing evidence of a major role for both the skin and gut microbiome.
In regard to the skin microbiome, Malassezia has long been recognized as linked to SD and is a target of treatment, but evidence that the gut microbiome might be participating is relatively new. One clue comes from the fact that oral antifungal therapies, such as itraconazole, are known to reduce risk for SD relapse, an effect that might be a function of their ability to modulate the gut microbiome, according to Dr. Kwatra.
Topical roflumilast, a phosphodiesterase-4 inhibitor, was effective for SD in a vehicle-controlled phase 3 trial published in 2023. He characterized the adverse event profile as “pretty clean,” but he emphasized that a role for many other strategies remains. This is particularly true for challenging forms of SD. For example, topical tacrolimus provided meaningful protection against relapse over a period of more than 6 months in a 2021 trial that enrolled patients with severe facial SD.
The topical Janus kinase inhibitor ruxolitinib, 1.5%, (approved for atopic dermatitis and vitiligo) has also been reported to be effective for refractory facial SD. It is being evaluated in a phase 2 study of SD, according to Dr. Kwatra. A topical PDE4 inhibitor is also being evaluated for SD in a phase 2 study, he said.
Given the heterogeneity of the presentation of SD and the value of combining different mechanisms of action, Dr. Kwatra does not think any drug by itself will be a cure for SD. However, the chances of success with current drug combinations are high.
It is for this reason that Dr. Kwatra encourages clinicians to look for this disease routinely, including among patients who have a different presenting complaint. “Patients do not always bring it up, so bring it up,” he said.
This is good advice, according to Andrew F. Alexis, MD, MPH, professor of clinical dermatology and Vice-chair for Diversity and Inclusion of the Department of Dermatology, Weill Cornell Medicine, New York City. He agreed that the recent introduction of a therapy approved by the FDA is an impetus to look for SD and to talk with patients about treatment options.
In addition, while he also considers roflumilast foam to be a first-line drug, he agreed that combination therapies might be needed to increase the likely of rapid control of scalp and skin involvement. “SD is probably underestimated as a clinical problem, and we do have good treatments to offer for the patients who are affected,” he said at the meeting.
Dr. Kwatra reported no relevant disclosures. Dr. Alexis reported financial relationships with more than 25 pharmaceutical companies.

Melanoma: Neoadjuvant Immunotherapy Provides Optimal Survival Results
BARCELONA, SPAIN — with immunotherapy or a targeted agent or targeted therapy plus immunotherapy, according to a large-scale pooled analysis from the International Neoadjuvant Melanoma Consortium.
Importantly, the analysis — presented at the annual meeting of the European Society for Medical Oncology — showed that achieving a major pathological response to neoadjuvant therapy is a key indicator of survival outcomes.
After 3 years of follow-up, the results showed that neoadjuvant therapy is not delaying melanoma recurrence, “it’s actually preventing it,” coinvestigator Hussein A. Tawbi, MD, PhD, Department of Melanoma Medical Oncology, University of Texas MD Anderson Cancer Center, Houston, said in an interview. That’s “a big deal.”
Since 2010, the introduction of novel adjuvant and neoadjuvant therapies for high-risk stage III resectable melanoma has led to incremental gains for patients, said Georgina V. Long, MD, PhD, BSc, chair of Melanoma Medical Oncology and Translational Research at the University of Sydney in Australia, who presented the results.
The first pooled analysis of neoadjuvant therapy in 189 patients, published in 2021, indicated that those who achieved a major pathological response — defined as either a pathological complete response (with no remaining vital tumor) or a near-complete pathological response (with vital tumor ≤ 10%) — had the best recurrence-free survival rates.
In the current study, the researchers expanded their cohort to include 818 patients from 18 centers. Patients received at least one dose of neoadjuvant therapy — either combination immunotherapy, combination of targeted and immunotherapy agents, or monotherapy with either an immune checkpoint inhibitor or a targeted agent.
The median age was 59 years, and 38% of patients were women. The median follow-up so far is 38.8 months.
Overall, the 3-year event-free survival was 74% in patients who received any immunotherapy, 72% in those who received immunotherapy plus a targeted BRAF/MEK therapy, and just 37% in those who received targeted therapy alone. Similarly, 3-year recurrence-free survival rates were highest in patients who received immunotherapy at 77% vs 73% in those who received immunotherapy plus a targeted BRAF/MEK therapy and just 37% in those who received targeted therapy alone.
Looking specifically at progressive death 1 (PD-1)–based immunotherapy regimens, combination therapy led to a 3-year event-free survival rate between 77% and 95%, depending on the specific combinations, vs 64% with PD-1 monotherapy and 37% with combination targeted therapy.
Overall, patients who had a major pathological response were more likely to be recurrence free at 3 years. The 3-year recurrence-free survival was 88% in patients with a complete response, 68% in those with a partial pathological response, and 40% in those without a response.
Patients who received immunotherapy were more likely to have major pathological response. The 3-year recurrence-free survival was about 94% in patients who received combination or monotherapy with immune checkpoint inhibition, and about 87% in those who received immunotherapy plus targeted therapy. The recurrence-free survival rate was much lower in patients given only BRAF/MEK inhibitors.
The current overall survival data, which are still immature, suggested a few differences when stratifying the patients by treatment. Almost all patients with a major pathological response were alive at 3 years, compared with 86% of those with a partial pathological response and 70% of those without a pathological response.
Overall, the results showed that immunotherapy — as either combination or monotherapy — is “quite a bit” better than targeted therapy with BRAF/MEK agents, which offers no substantial benefit, said Dr. Twabi.
“When you see the same pattern happening in study after study, in a very clear, robust way, it actually becomes very powerful,” he explained.
Rebecca A. Dent, MD, MSc, chair of the ESMO Scientific Committee who was not involved in the study, told a press conference that the introduction of immunotherapy and combination immunotherapy has dramatically changed outcomes in melanoma.
Commenting on the current study results, Dr. Dent said that “combination immunotherapy is clearly showing exceptional stability in terms of long-term benefits.”
The question now is what are the toxicities and costs that come with combination immunotherapy, said Dr. Dent, from National Cancer Centre Singapore and Duke-NUS Medical School, Singapore.
No funding source was declared. Dr. Long declared relationships with a variety of companies, including AstraZeneca UK Limited, Bayer Healthcare Pharmaceuticals, Boehringer Ingelheim, Merck Sharp & Dohme, Novartis, and Regeneron. Dr. Twabi declared relationships with Bristol-Myers Squibb, Novartis, Merck, Genentech, GlaxoSmithKline, Eisai, and others. Dr. Dent declared relationships with AstraZeneca, Roche, Eisai, Gilead Sciences, Eli Lilly, Merck, and Pfizer.

Long, MD, PhD, BSc, chair of Melanoma Medical Oncology and Translational Research at the University of Sydney in Australia, who presented the results.
The first pooled analysis of neoadjuvant therapy in 189 patients, published in 2021, indicated that those who achieved a major pathological response — defined as either a pathological complete response (with no remaining vital tumor) or a near-complete pathological response (with vital tumor ≤ 10%) — had the best recurrence-free survival rates.
In the current study, the researchers expanded their cohort to include 818 patients from 18 centers. Patients received at least one dose of neoadjuvant therapy — either combination immunotherapy, combination of targeted and immunotherapy agents, or monotherapy with either an immune checkpoint inhibitor or a targeted agent.
The median age was 59 years, and 38% of patients were women. The median follow-up so far is 38.8 months.
Overall, the 3-year event-free survival was 74% in patients who received any immunotherapy, 72% in those who received immunotherapy plus a targeted BRAF/MEK therapy, and just 37% in those who received targeted therapy alone. Similarly, 3-year recurrence-free survival rates were highest in patients who received immunotherapy at 77% vs 73% in those who received immunotherapy plus a targeted BRAF/MEK therapy and just 37% in those who received targeted therapy alone.
Looking specifically at progressive death 1 (PD-1)–based immunotherapy regimens, combination therapy led to a 3-year event-free survival rate between 77% and 95%, depending on the specific combinations, vs 64% with PD-1 monotherapy and 37% with combination targeted therapy.
Overall, patients who had a major pathological response were more likely to be recurrence free at 3 years. The 3-year recurrence-free survival was 88% in patients with a complete response, 68% in those with a partial pathological response, and 40% in those without a response.
Patients who received immunotherapy were more likely to have major pathological response. The 3-year recurrence-free survival was about 94% in patients who received combination or monotherapy with immune checkpoint inhibition, and about 87% in those who received immunotherapy plus targeted therapy. The recurrence-free survival rate was much lower in patients given only BRAF/MEK inhibitors.
The current overall survival data, which are still immature, suggested a few differences when stratifying the patients by treatment. Almost all patients with a major pathological response were alive at 3 years, compared with 86% of those with a partial pathological response and 70% of those without a pathological response.
Overall, the results showed that immunotherapy — as either combination or monotherapy — is “quite a bit” better than targeted therapy with BRAF/MEK agents, which offers no substantial benefit, said Dr. Twabi.
“When you see the same pattern happening in study after study, in a very clear, robust way, it actually becomes very powerful,” he explained.
Rebecca A. Dent, MD, MSc, chair of the ESMO Scientific Committee who was not involved in the study, told a press conference that the introduction of immunotherapy and combination immunotherapy has dramatically changed outcomes in melanoma.
Commenting on the current study results, Dr. Dent said that “combination immunotherapy is clearly showing exceptional stability in terms of long-term benefits.”
The question now is what are the toxicities and costs that come with combination immunotherapy, said Dr. Dent, from National Cancer Centre Singapore and Duke-NUS Medical School, Singapore.
No funding source was declared. Dr. Long declared relationships with a variety of companies, including AstraZeneca UK Limited, Bayer Healthcare Pharmaceuticals, Boehringer Ingelheim, Merck Sharp & Dohme, Novartis, and Regeneron. Dr. Twabi declared relationships with Bristol-Myers Squibb, Novartis, Merck, Genentech, GlaxoSmithKline, Eisai, and others. Dr. Dent declared relationships with AstraZeneca, Roche, Eisai, Gilead Sciences, Eli Lilly, Merck, and Pfizer.

Identifying Drug-Induced Rashes in Skin of Color: Heightened Awareness Can Accelerate Diagnosis
NEW YORK — Because of their heterogeneity in appearance, to speed the diagnosis.
This risk for a delayed or missed diagnosis in patients with darker skin is shared across skin rashes, but drug-induced hypersensitivity syndrome (DIHS) is a telling example, according to Joanna Harp, MD, director of the Inpatient Dermatology Consult Service, NewYork–Presbyterian Hospital, New York City.
DIHS, also known as a drug reaction with eosinophilia and systemic symptoms, is a type IV hypersensitivity reaction, Dr. Harp explained. While the fact that this disorder does not always include eosinophilia prompted the DIHS acronym, the maculopapular rash often serves as a critical clue of the underlying etiology.
In patients with darker skin, DIHS skin manifestations “can look different, can be more severe, and can have worse outcomes,” Dr. Harp said. As with other skin rashes that are primarily erythematous, the DIHS rash is often more subtle in Black-skinned patients, typically appearing gray or violaceous rather than red.
“The high amount of scale can be a clue,” said Dr. Harp, speaking at the 2024 Skin of Color Update. Scale is particularly prominent among Black patients, she said, because of the greater relative transepidermal water loss than lighter skin, increasing dryness and susceptibility to scale.
The maculopapular rash is “similar to a simple drug eruption, although it is usually more impressive,” she said. Emphasizing that DIHS is a systemic disease, she noted that the characteristic rash is typically accompanied by inflammation in multiple organs that not only includes the mucous membranes but can include major organs such as the lungs, kidneys, and heart.
In patients with DIHS and many of the even more serious types of rashes traced to drug exposures, such as Stevens-Johnson syndrome (SJS) or erythema multiforme, the delay to appearance of the rash from the time of exposure can be the most confusing element.
“It can be months for some drugs such as allopurinol,” said Dr. Harp, pointing out that Black and Asian patients are more likely to carry the HLA-B*5801 genotype, a known risk factor for allopurinol hypersensitivity.
Signs of AGEP Can Be Subtle in Black Patients
Some of the same principles for diagnosing drug-induced rash in darker skin can also be applied to acute generalized exanthematous pustulosis (AGEP), another type IV hypersensitivity reaction. Like all drug-induced rashes, the earlier AGEP is recognized and treated, the better the outcome, but in Black patients, the signs can be subtle.
“The onset is usually fast and occurs in 1-2 days after [the causative drug] exposure,” said Dr. Harp, adding that antibiotics, such as cephalosporins or penicillin, and calcium channel blockers are among the prominent causes of AGEP.
One of the hallmark signs of early-onset AGEP are tiny erythematous pustules in flexural areas, such as the neck or the armpits. The issue of detecting erythema in darker skin is also relevant to this area, but there is an additional problem, according to Dr. Harp. The pustules often dry up quickly, leaving a neutrophilic scale that further complicates the effort to see the characteristic erythema.
“If you see a lot of scale, look for erythema underneath. Think of inflammation,” Dr. Harp said, explaining that the clinical appearance evolves quickly. “If you do not see the pustules, it does not mean they were not there; you just missed them.”
In addition to the flexural areas, “AGEP loves the ears, the face, and the geographic tongue,” she said, offering several pearls to help with the diagnosis. These include side lighting to make papules easier to see, pressing on the skin to highlight the difference between erythematous skin and blanched skin, and checking less pigmented skin, such as on the hands and feet, which makes erythema easier to see.
Steroids are often the first-line treatment for drug-induced skin rashes, but Dr. Harp moves to etanercept or cyclosporine for the most serious drug reactions, such as SJS and toxic epidermal necrolysis.
Etanercept is typically her first choice because patients with systemic hypersensitivity reactions with major organ involvement are often quite ill, making cyclosporine harder to use. In her experience, etanercept has been well tolerated.
Conversely, she cautioned against the use of intravenous immunoglobulin (IVIG). Although this has been used traditionally for severe drug hypersensitivity reactions, “the data are not there,” she said. The data are stronger for a combination of high-dose steroids and IVIG, but she thinks even these data are inconsistent and not as strong as the data supporting etanercept or cyclosporine. She encouraged centers still using IVIG to consider alternatives.
After drug sensitivity reactions are controlled, follow-up care is particularly important for Black patients who face greater risks for sequelae, such as hypopigmentation, hyperpigmentation, or keloids. She recommended aggressive use of emollients and sunscreens for an extended period after lesions resolve to lessen these risks.
Differences in the manifestations of drug-induced skin rashes by race and ethnicity are important and perhaps underappreciated, agreed Shawn Kwatra, MD, professor and chairman of the Department of Dermatology, University of Maryland, Baltimore.
Asked to comment at the meeting, Dr. Kwatra said that he appreciated Dr. Harp’s effort to translate published data and her experience into an overview that increases awareness of the risk for missed or delayed diagnoses of drug-induced rashes in skin of color. He noted that the strategies to identify erythema and pustules, such as increased suspicion in skin of color and the extra steps to rule them out, such as the use of side lighting in the case of pustules for AGEP, are simple and practical.
Dr. Harp and Dr. Kwatra had no relevant disclosures.

FDA Initiative Aims to Improve Diversity in Clinical Trials
NEW YORK — Underrepresentation by gender and race in major clinical trials has been a cause for complaint for decades, but the Food and Drug Administration (FDA) has drafted a regulatory solution to this issue expected to be implemented sometime in 2025.
This initiative, known as the according to Valerie M. Harvey, MD, MPH, associate clinical professor, Edward Via College of Osteopathic Medicine, Blacksburg, Virginia. These rules will be codified, she said at the 2024 Skin of Color Update.
Once the DAP is enacted, “the sponsor must specify the rationale and goals for study enrollment by age, ethnicity, sex, and race,” she said. Furthermore, the submission to the FDA must “describe the methods to meet the diversity benchmarks.”
Lack of Trial Diversity Is Common Across Medicine
Although she focused on the relevance of this initiative to dermatology, Dr. Harvey said the lack of diversity in clinical trials is pervasive throughout medicine. In one survey of randomized controlled trials, less than 60% of trials even specified the race and ethnicity of the participants. In recent psoriasis trials, only 30% met a diversity definition of ≥ 20% of patients identifying as minority (Black, Hispanic, Asian, or other non-White group), said Dr. Harvey, who practices dermatology in Newport News, Virginia.
The FDA draft guidance for the DAP was released in June 2024 and is now available for submitting comments (until September 26). The plan is expected to be published in June 2025, according to Dr. Harvey. It will pertain to all pivotal and phase 3 trials enrolling 180 days after the publication date and will be relevant to all drugs and biologics as well as certain devices.
This initiative could be a critical step toward ensuring diversity in major clinical trials after years of stagnation, Dr. Harvey said, noting that despite repeated calls for more diversity in clinical trials, the literature suggests “little progress.”
However, she said that increasing diversity in clinical trials is just one step toward gathering data about the generalizability of efficacy and safety across racial and ethnic groups. A much more complex issue involves how race and ethnicity are defined in order to understand differences, if any, for efficacy and risk.
“Race is a dynamic social construct and a poor measure for biologic variation and skin color,” Dr. Harvey said. This means that work is needed to address the more complex issue of race and ethnicity stratification that will help clinicians understand the relative benefits and risks for the drugs in these trials.
Rather than differences based on genetic or other sources of biologic differences, she said, outcomes by race alone are often suspected of reflecting disparities in access to healthcare rather than a difference in therapeutic response.
Skin Color Is Inadequate to Define Race
When stratifying patients by race or ethnicity, Dr. Harvey said that “we have to be very, very careful in considering the study purpose and what the study question is.” A study attempting to compare benefits and risks among subgroups by race or ethnicity will require descriptors beyond skin color.
The recognized limitations of measuring skin tone as a surrogate of race are one reason for widespread interest in moving away from the Fitzpatrick skin type (FST) rating that has been widely considered a standard, according to Dr. Harvey. Several alternatives have been proposed, including the Monk Skin Tone Scale, the Individual Typology Angle, and the Eumelanin Human Skin Color Scale, but she cautioned that these are less well validated and generally have the limitations of the FST.
If skin color was ever useful for grouping individuals on the basis of shared physiology, growing rates of intermarriage and immigration have made skin color increasingly irrelevant to racial identity. If the goal is to evaluate the safety and efficacy of drugs across racial groups and ethnicities, the characterization of populations will almost certainly require multiple descriptors and biomarkers, she said.
“It is very important to have many tools for characterizing patients by skin type,” Susan Taylor, MD, professor of dermatology and vice chair for diversity, equity, and inclusion for the Department of Dermatology, University of Pennsylvania, Philadelphia, said in an interview at the meeting.
The reason is “there are limitations to all of them,” she said, noting also that the questions being asked about how and if skin color and race are relevant to therapeutic options differ by the question, such as innate response or access to care.
Dr. Taylor is part of a workshop that she said is evaluating a combination of instruments for characterizing skin color and race in ways relevant to the specific question being asked.
The solutions might differ. While simple clinical assessments involving skin color might be made with methods captured on a smartphone app, Dr. Taylor acknowledged that far more complex tools might be required to document the effect of racial or ethnic differences in drug efficacy and safety in a research setting.
Outside of a research setting, any tools that might be useful for assessing race as a variable must be practical, according to Dr. Harvey. She suggested that these must be time efficient, of reasonable cost, and most importantly, reliable.
Tools meeting these criteria do not currently exist, but Dr. Harvey said the work is underway. She expects a “top-down” collaborative approach to validate alternatives to the FST. If such tools can be developed with buy-in from the FDA, they might be particularly useful for translating trial data to patient care, she added.
Dr. Harvey reported financial relationships with AbbVie, Bristol-Myers Squibb, Janssen, Johnson & Johnson, L’Oréal, and SkinCeuticals. Dr. Taylor, president-elect of the American Academy of Dermatology, reported financial relationships with more than 25 pharmaceutical and cosmetic companies.

If the goal is to evaluate the safety and efficacy of drugs across racial groups and ethnicities, the characterization of populations will almost certainly require multiple descriptors and biomarkers, she said.
“It is very important to have many tools for characterizing patients by skin type,” Susan Taylor, MD, professor of dermatology and vice chair for diversity, equity, and inclusion for the Department of Dermatology, University of Pennsylvania, Philadelphia, said in an interview at the meeting.
The reason is “there are limitations to all of them,” she said, noting also that the questions being asked about how and if skin color and race are relevant to therapeutic options differ by the question, such as innate response or access to care.
Dr. Taylor is part of a workshop that she said is evaluating a combination of instruments for characterizing skin color and race in ways relevant to the specific question being asked.
The solutions might differ. While simple clinical assessments involving skin color might be made with methods captured on a smartphone app, Dr. Taylor acknowledged that far more complex tools might be required to document the effect of racial or ethnic differences in drug efficacy and safety in a research setting.
Outside of a research setting, any tools that might be useful for assessing race as a variable must be practical, according to Dr. Harvey. She suggested that these must be time efficient, of reasonable cost, and most importantly, reliable.
Tools meeting these criteria do not currently exist, but Dr. Harvey said the work is underway. She expects a “top-down” collaborative approach to validate alternatives to the FST. If such tools can be developed with buy-in from the FDA, they might be particularly useful for translating trial data to patient care, she added.
Dr. Harvey reported financial relationships with AbbVie, Bristol-Myers Squibb, Janssen, Johnson & Johnson, L’Oréal, and SkinCeuticals. Dr. Taylor, president-elect of the American Academy of Dermatology, reported financial relationships with more than 25 pharmaceutical and cosmetic companies.
