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.

Air pollution, high temperatures, and metabolic risk factors are driving global increases in stroke, contributing to 12 million cases and more than 7 million deaths from stroke each year, new data from the Global Burden of Disease (GBD) study showed.

Between 1990 and 2021, the number of people who experienced a stroke increased to 11.9 million (up by 70% since 1990), while the number of stroke survivors rose to 93.8 million (up by 86%), and stroke-related deaths rose to 7.3 million (up by 44%), making stroke the third leading cause of death worldwide after ischemic heart disease and COVID-19, investigators found.

Stroke is highly preventable, the investigators noted, with 84% of the stroke burden in 2021 attributable to 23 modifiable risk factors, including air pollution, excess body weight, high blood pressure, smoking, and physical inactivity.

This means there are “tremendous opportunities to alter the trajectory of stroke risk for the next generation,” Catherine O. Johnson, MPH, PhD, co-author and lead research scientist at the Institute for Health Metrics and Evaluation (IHME), University of Washington, Seattle, said in a news release.

The study was published online in The Lancet Neurology.
 

Top Risk Factor for Subarachnoid Hemorrhage

Since 1990, the contribution of high temperatures to poor health and early death due to stroke has risen 72%, a trend likely to increase in the future — underscoring the impact of environmental factors on the growing stroke burden, the authors said.

“Given that ambient air pollution is reciprocally linked with ambient temperature and climate change, the importance of urgent climate actions and measures to reduce air pollution cannot be overestimated,” Dr. Johnson said.

Mitchell S.V. Elkind, MD, MS, chief clinical science officer for the American Heart Association, who wasn’t involved in the study, told this news organization that environmental factors such as air pollution, particulate matter from wildfires and other sources, and excessive heat are now recognized as major contributors to the risk for stroke. “This should not be surprising as we have long recognized the risks of stroke associated with toxins in cigarette smoke, which likely share mechanisms for vascular damage with pollutants,” Dr. Elkind said.

The data also reveal for the first time that ambient particulate matter air pollution is a top risk factor for subarachnoid hemorrhage, contributing to 14% of the death and disability caused by this serious stroke subtype, on a par with smoking.

Dr. Elkind noted that smoking is “a major risk factor for subarachnoid hemorrhage. It makes sense that particulate air pollution would therefore similarly be a risk factor for subarachnoid hemorrhage, which similarly damages blood vessels. Prior studies were likely too small or did not assess the role of air pollution in subarachnoid hemorrhage.”

The analysis also showed substantial increases between 1990 and 2021 in the global stroke burden linked to high body mass index (up by 88%), high blood sugar (up 32%), a diet high in sugar-sweetened drinks (up 23%), low physical activity (up 11%), high systolic blood pressure (up 7%), and a diet low in omega-6 polyunsaturated fatty acids (up 5%).

“And with increasing exposure to risk factors such as high blood sugar and diet high in sugar-sweetened drinks, there is a critical need for interventions focused on obesity and metabolic syndromes,” Dr. Johnson said.

“Identifying sustainable ways to work with communities to take action to prevent and control modifiable risk factors for stroke is essential to address this growing crisis,” she added.
 

Prevention Strategies Fall Short

The data also showed that stroke-related disability-adjusted life-years rose from around 121.4 million years of healthy life lost in 1990 to 160.5 million years in 2021, making stroke the fourth leading cause of health loss worldwide after COVID-19, ischemic heart disease, and neonatal disorders.

“The global growth of the number of people who develop stroke and died from or remain disabled by stroke is growing fast, strongly suggesting that currently used stroke prevention strategies are not sufficiently effective,” lead author Valery L. Feigin, MD, PhD, from Auckland University of Technology, Auckland, New Zealand, and affiliate professor at IHME, said in the release.

“New, proven effective population-wide and motivational individual prevention strategies that could be applied to all people at risk of having a stroke, regardless of the level of risk, as recommended in the recent Lancet Neurology Commission on Stroke should be implemented across the globe urgently,” said Dr. Feigin.

Dr. Elkind said the AHA supports research on the effects of air quality on risk for vascular injury and stroke and has “long advocated for policies to mitigate the adverse health impacts of air pollutants, including reduction of vehicle emissions and renewable portfolio standards, taking into account racial, ethnic, and economic disparities.”

“AHA, and the healthcare sector more broadly, must take a leadership role in recommending policies to improve environmental air quality and in working with the private sector and industry to improve air quality,” Dr. Elkind said.

In an accompanying commentary, Ming Liu, MD, and Simiao Wu, MD, PhD, West China Hospital, Sichuan University, Chengdu, China, wrote that “pragmatic solutions to the enormous and increasing stroke burden include surveillance, prevention, acute care, and rehabilitation.”

“Surveillance strategies include establishing a national-level framework for regular monitoring of stroke burden, risk factors, and healthcare services via community-based surveys and health records,” they noted.

“Artificial intelligence and mobile technologies might not only facilitate the dissemination of evidence-based health services but also increase the number of data sources and encourage participation of multidisciplinary collaborators, potentially improving the validity and accuracy of future GBD estimates,” they added.

TOPLINE:

Black women in the United States have higher breast cancer (BC) mortality rates than White women across tumor subtypes. The greatest disparity in BC-specific survival was observed in those with hormone receptor-positive (HR+), human epidermal growth factor 2–negative (HER2−) tumors, with Black women having a 50% higher risk for death.

METHODOLOGY:

• US Black women have a 40% higher risk for death from BC than White women, and many cancer specialists believe that disparities are worse among more treatable subtypes, such as HR+ tumors.
• Researchers conducted a systematic review and meta-analysis of 18 US studies published during 2009-2022 that included 228,885 women (34,262 Black women; 182,466 White women) and examined racial differences in BC survival by subtype.
• The analysis included hormone receptor and HER2/neu status to define subtypes: HR+ HER2+, HR+ HER2−, HR− HER2+, and HR− HER2−.
• Random-effects models were used to generate pooled relative risks and 95% CI for BC-specific survival and overall survival.
• The primary outcome was BC-specific survival, with overall survival as a secondary analysis.

TAKEAWAY:

• Black women had a higher risk for BC death across all tumor subtypes than White women, with the greatest disparity observed in HR+ HER2− tumors (hazard ratio [HR], 1.50; 95% CI, 1.30-1.72).
• The risk for BC death was also higher for Black women with HR+ HER2+ tumors (HR, 1.34; 95% CI, 1.10-1.64); HR− HER2+ tumors (HR, 1.20; 95% CI, 1.00-1.43); and HR− HER2− tumors (HR, 1.17; 95% CI, 1.10-1.25).
• Overall survival was poorer for Black women across all subtypes, although estimates for HR− HER2+ tumors did not reach statistical significance.
• In analysis of two subtypes with significant heterogeneity among studies, adjustments for socioeconomic status and number of Black participants explained about half and all the variance for HR+ HER2− and HR− HER2+ tumors, respectively.

IN PRACTICE:

“These results suggest there are both subtype-specific and subtype-independent mechanisms that contribute to disparities in breast cancer survival between Black and White women, which require multilevel interventions to address and achieve health equity,” wrote the authors.

SOURCE:

The study was led by Juliana M. Torres, Dana-Farber/Harvard Cancer Center, CURE Program, Boston. It was published online in the Journal of Clinical Oncology.

LIMITATIONS:

The study’s limitations included potential heterogeneity between studies as indicated by significant heterogeneity in some analyses. The use of different subtype definitions and potential overlap in data sets may have also affected the results. Many included studies did not capture the extent to which treatments were completed or detection and treatment of recurrences. Additionally, the study’s findings may not fully capture socioeconomic inequality and other unmeasured factors contributing to disparities. The racial and ethnic disparities analysis focused only on Black and White women.

DISCLOSURES:

Individual authors disclosed financial relationships with Pfizer, Healthix, Merck, AstraZeneca, LabCorp, and Takeda. Additional disclosures are noted in the original article.

Early use of mycophenolate mofetil (MMF), a drug used to dampen the immune system in organ transplant recipients, may reduce the risk for severe flares in patients with newly diagnosed systemic lupus erythematosus (SLE), according to results from a randomized, open-label, observer-blinded clinical trial.

In interviews, two SLE specialists who were not involved with the study said the research is preliminary but promising. However, another specialist criticized the paper’s reliance on unusual doses of prednisone and MMF, saying it “puts people on a treatment regimen that nobody ever uses.”

The Lupus Foundation of America estimates that about 16,000 people in the United States are diagnosed with lupus each year. “Our current treatment paradigm is to go pretty slowly and start treatment for new-onset, mild SLE with glucocorticoids, if necessary, and hydroxychloroquine,” said Karen H. Costenbader, MD, MPH, of Harvard Medical School and Harvard School of Public Health, Boston, Massachusetts.

Stronger immunosuppressive agents may be added as patients progress, she said.

Off-label use of MMF, which is approved by the Food and Drug Administration only for patients with certain organ transplants, may be appropriate in some cases, she said. “There is a big push to start immunosuppressives earlier, but we currently would reserve mycophenolate for those with severe manifestations — lupus nephritis; vasculitis; or lung, brain, or heart inflammation.”

In the trial, adult patients who received oral prednisone (starting at 0.5 mg/kg per day) and hydroxychloroquine sulfate (5 mg/kg per day) plus MMF (500 mg twice daily) for 96 weeks were less likely to develop severe flares than those who took the regimen without MMF (relative risk [RR], 0.39; 95% CI, 0.17-0.87; P = .01). Severe flares occurred in 10.8% of the MMF group (7 of 65 patients) and in 27.7% of the control group (18 of 65), Yijun You, MD, of Ruijin Hospital, Shanghai Jiao Tong University School of Medicine, Shanghai, China, and colleagues reported in JAMA Network Open. 

Patients in the MMF group also had 89% lower risk for lupus nephritis than those in the control group (RR, 0.11; 95% CI, 0.01-0.85; P = .008), with kidney involvement occurring in 1.5% (1 of 65) vs 13.8% (9 of 65).

During 2018-2021, researchers recruited 130 patients in China aged 18-65 years with newly diagnosed SLE, a high titer of anti–double-stranded DNA (dsDNA) antibodies, and no major organ involvement (mean age, 34.5 years; 86.2% women). Patients’ initial 0.5–mg/kg per day prednisone dose was maintained for 4 weeks, then tapered by 5.0 mg every 2 weeks, and when the dose had been reduced to 20.0 mg/day, it was tapered by 5 mg every month and then gradually to 0.1-0.2 mg/kg per day. If patients had severe flares, they stopped taking MMF. (The study authors did not respond to requests for comment on the study.) 
 

‘A Treatment Regimen That Nobody Ever Uses’

While Dr. Costenbader called the study “very interesting” and said “every person diagnosing or taking care of patients with lupus should be familiar” with it, she noted that the prednisone doses were high. “I am wondering why they used quite so much glucocorticoid for everyone. This may have masked some of the MMF effect and biased toward the null. They also used a low dose of MMF and did not ramp it up as we would normally to a full dose. That being said, it is remarkable that it was well-tolerated and resulted in better outcomes over the period of the trial.”

Cedars-Sinai Medical Center

Daniel J. Wallace, MD, of Cedars-Sinai Medical Center, Los Angeles, California, and the University of California, Los Angeles, also highlighted the high doses of prednisone and low doses of MMF. “It’s a useless paper that puts people on a treatment regimen that nobody ever uses,” he said.

The rates of mild to moderate flares were similar between the control and intervention groups (38.5% vs 36.9%, respectively; RR, 0.96; P = .90). This finding is surprising, said Judith A. James, MD, PhD, executive vice president, chief medical officer, and head of the rheumatology clinic and Arthritis and Clinical Immunology Research Program at the Oklahoma Medical Research Foundation in Oklahoma City and also the Associate Vice Provost of Clinical & Translational Science, professor of medicine, and George Lynn Cross Research Professor at the University of Oklahoma Health Sciences Center in Oklahoma City. “It may be that mild flares have a different mechanism or are caused by noninflammatory endotypes that don’t respond to MMF.”

Dr. Costenbader noted that a risk-benefit analysis will need to be done to take the risks of MMF into account. “However, every time that a person flares or is not in lupus low-disease activity state, potentially permanent organ damage is done and the patient suffers,” she said. “Preventing lupus nephritis de novo was also seen — nine cases potentially prevented — and that is also really interesting. It would be amazing if we could completely avoid that life-threatening complication.”

MMF can cause miscarriage and boost the risk for birth defects, and the manufacturer says it can lower the effectiveness of birth control pills. It can also boost the risk for some cancers such as lymphoma and increase the risk for infections.

Surprisingly, the number of adverse events in the control and intervention groups were similar (35.4% vs 46.2%, respectively; RR, 1.30; 95% CI, 0.86-1.99; P = .20). They included infection (30.8% vs 33.8%, respectively; P = .70) and gastrointestinal tract events (16.9% for both; P > .99).

“There were overall pretty similar rates of side effects, but maybe this was because MMF dose was pretty low in the treated group, or the glucocorticoid dose was not so low in both groups,” Dr. Costenbader said. She also noted that “the risk of malignancy with MMF is longer term than this study. It may not show up for 5-10 or even more years, but we know it exists. Infections are also increased with MMF — some of which can be avoided with vaccines for COVID, pneumonia, influenza, shingles, etc. MMF also causes gastrointestinal intolerance, and people often are not able to take it because of nausea, vomiting, diarrhea, and elevated liver function tests.”

Dr. James said the infection rates “may be due to the higher doses of steroids patients in both groups are on for several months at the beginning of the study.”

A total of 12 patients in the MMF group discontinued the intervention for various reasons, and 6 were lost to follow-up. In the control group, 20 discontinued the intervention and two were lost to follow-up. However, all 130 patients in the trial were included in the primary and secondary outcome analyses.

Should clinicians consider prescribing MMF to patients with new-onset SLE? “We usually wait until later when there are indications of more severe disease, but here they started it from the time of diagnosis if the patient was anti-dsDNA positive. Given insurance restrictions in this country, we would be unlikely to be able to do that for many patients,” Dr. Costenbader said. “They likely also overtreated a lot of patients who didn’t need it. Due to our lack of more specific biomarkers and precision medicine for lupus, we do currently undertreat a lot of patients, as this study highlights, as well as overtreat others.”
 

How Much Might Cost Factor Into Treatment Decisions?

The study did not examine cost. Prednisone and hydroxychloroquine sulfate are inexpensive, but Dr. James said MMF can cost about $450 a month at the study dosage. However, “the average hospitalization without an ICU [intensive care unit] visit for an SLE patient is about $15,000-$20,000. If you can avoid one hospitalization, you can pay for nearly 4 years of MMF. More importantly, from a financial perspective, if you can convert a severe lupus patient to a mild/moderate lupus patient, then the annual costs of lupus decrease nearly by half, from about $52,000 per year to $25,000 per year.”

The study authors noted various limitations such as the small number of subjects, the need for a longer trial “to determine the advantages and disadvantages of early application of MMF,” and the fact that all subjects were Asian. The authors also called for confirmation via a double-blind, placebo-controlled study.

The study was funded by grants to the authors by the National Natural Science Foundation of China, Shanghai Rising-Star Program, Natural Science Foundation of Shanghai, Five-Year National Key R&D Program, and Ruijin–Zhongmei Huadong Lupus Funding. The authors had no disclosures. Dr. Costenbader disclosed consulting/research collaboration relationships with AstraZeneca, Amgen, Biogen, Bristol-Myers Squibb, GSK, Merck, Gilead, and Cabaletta.

Early use of mycophenolate mofetil (MMF), a drug used to dampen the immune system in organ transplant recipients, may reduce the risk for severe flares in patients with newly diagnosed systemic lupus erythematosus (SLE), according to results from a randomized, open-label, observer-blinded clinical trial.

In interviews, two SLE specialists who were not involved with the study said the research is preliminary but promising. However, another specialist criticized the paper’s reliance on unusual doses of prednisone and MMF, saying it “puts people on a treatment regimen that nobody ever uses.”

The Lupus Foundation of America estimates that about 16,000 people in the United States are diagnosed with lupus each year. “Our current treatment paradigm is to go pretty slowly and start treatment for new-onset, mild SLE with glucocorticoids, if necessary, and hydroxychloroquine,” said Karen H. Costenbader, MD, MPH, of Harvard Medical School and Harvard School of Public Health, Boston, Massachusetts.

Stronger immunosuppressive agents may be added as patients progress, she said.

Off-label use of MMF, which is approved by the Food and Drug Administration only for patients with certain organ transplants, may be appropriate in some cases, she said. “There is a big push to start immunosuppressives earlier, but we currently would reserve mycophenolate for those with severe manifestations — lupus nephritis; vasculitis; or lung, brain, or heart inflammation.”

In the trial, adult patients who received oral prednisone (starting at 0.5 mg/kg per day) and hydroxychloroquine sulfate (5 mg/kg per day) plus MMF (500 mg twice daily) for 96 weeks were less likely to develop severe flares than those who took the regimen without MMF (relative risk [RR], 0.39; 95% CI, 0.17-0.87; P = .01). Severe flares occurred in 10.8% of the MMF group (7 of 65 patients) and in 27.7% of the control group (18 of 65), Yijun You, MD, of Ruijin Hospital, Shanghai Jiao Tong University School of Medicine, Shanghai, China, and colleagues reported in JAMA Network Open. 

Patients in the MMF group also had 89% lower risk for lupus nephritis than those in the control group (RR, 0.11; 95% CI, 0.01-0.85; P = .008), with kidney involvement occurring in 1.5% (1 of 65) vs 13.8% (9 of 65).

During 2018-2021, researchers recruited 130 patients in China aged 18-65 years with newly diagnosed SLE, a high titer of anti–double-stranded DNA (dsDNA) antibodies, and no major organ involvement (mean age, 34.5 years; 86.2% women). Patients’ initial 0.5–mg/kg per day prednisone dose was maintained for 4 weeks, then tapered by 5.0 mg every 2 weeks, and when the dose had been reduced to 20.0 mg/day, it was tapered by 5 mg every month and then gradually to 0.1-0.2 mg/kg per day. If patients had severe flares, they stopped taking MMF. (The study authors did not respond to requests for comment on the study.) 
 

‘A Treatment Regimen That Nobody Ever Uses’

While Dr. Costenbader called the study “very interesting” and said “every person diagnosing or taking care of patients with lupus should be familiar” with it, she noted that the prednisone doses were high. “I am wondering why they used quite so much glucocorticoid for everyone. This may have masked some of the MMF effect and biased toward the null. They also used a low dose of MMF and did not ramp it up as we would normally to a full dose. That being said, it is remarkable that it was well-tolerated and resulted in better outcomes over the period of the trial.”

Cedars-Sinai Medical Center

Daniel J. Wallace, MD, of Cedars-Sinai Medical Center, Los Angeles, California, and the University of California, Los Angeles, also highlighted the high doses of prednisone and low doses of MMF. “It’s a useless paper that puts people on a treatment regimen that nobody ever uses,” he said.

The rates of mild to moderate flares were similar between the control and intervention groups (38.5% vs 36.9%, respectively; RR, 0.96; P = .90). This finding is surprising, said Judith A. James, MD, PhD, executive vice president, chief medical officer, and head of the rheumatology clinic and Arthritis and Clinical Immunology Research Program at the Oklahoma Medical Research Foundation in Oklahoma City and also the Associate Vice Provost of Clinical & Translational Science, professor of medicine, and George Lynn Cross Research Professor at the University of Oklahoma Health Sciences Center in Oklahoma City. “It may be that mild flares have a different mechanism or are caused by noninflammatory endotypes that don’t respond to MMF.”

Dr. Costenbader noted that a risk-benefit analysis will need to be done to take the risks of MMF into account. “However, every time that a person flares or is not in lupus low-disease activity state, potentially permanent organ damage is done and the patient suffers,” she said. “Preventing lupus nephritis de novo was also seen — nine cases potentially prevented — and that is also really interesting. It would be amazing if we could completely avoid that life-threatening complication.”

MMF can cause miscarriage and boost the risk for birth defects, and the manufacturer says it can lower the effectiveness of birth control pills. It can also boost the risk for some cancers such as lymphoma and increase the risk for infections.

Surprisingly, the number of adverse events in the control and intervention groups were similar (35.4% vs 46.2%, respectively; RR, 1.30; 95% CI, 0.86-1.99; P = .20). They included infection (30.8% vs 33.8%, respectively; P = .70) and gastrointestinal tract events (16.9% for both; P > .99).

Histopathologic analysis of debulk specimens in Mohs micrographic surgery (MMS) may augment identification of high-risk factors in cutaneous squamous cell carcinoma (cSCC), which may warrant tumor upstaging.¹ Intratumor location has not been studied when looking at these high-risk factors. Herein, we report 4 cSCCs initially categorized as well differentiated that were reclassified as moderate to poorly differentiated on analysis of debulk specimens obtained via shave removal.

An 80-year-old man (patient 1) presented with a tender 2-cm erythematous plaque with dried hemorrhagic crusting on the frontal scalp. He had a history of nonmelanoma skin cancers. A biopsy revealed a ­well-differentiated cSCC, which was upgraded from a T2a tumor to T2b during MMS due to galea involvement. Debulk analysis revealed moderate to poorly differentiated cSCC, with the least-differentiated cells at the deep margin (Figure 1A). Given T2b staging, baseline imaging and radiation therapy were recommended.

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.

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.

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).

The US Food and Drug Administration (FDA) approved ribociclib (Kisqali, Novartis) in combination with an aromatase inhibitor for adult patients with hormone receptor (HR)-positive, human epidermal growth factor receptor 2 (HER2)-negative stages II and III breast cancer at high risk for recurrence following surgery.

FDA also approved ribociclib and the aromatase inhibitor letrozole packaged together (Kisqali Femara Co-Pack, Novartis) for the same indication.

A rival cyclin-dependent kinase 4/6 (CDK4/6) inhibitor abemaciclib (Verzenio, Eli Lilly) carries a similar adjuvant indication, but use of this agent requires patients to be lymph node–positive.

There’s no such restriction for the new ribociclib indication, which “allows us to offer treatment with a CDK4/6 inhibitor to a significantly broader group of people,” lead investigator Dennis J. Slamon, MD, breast oncologist at the University of California Los Angeless, said in a Novartis press release.

The new indication joins ribociclib’s previous approval for advanced or metastatic HR-positive, HER2-negative breast cancer in combination with an aromatase inhibitor or fulvestrant.

The current approval was based on data from the NATALEE trial. NATALEE randomized 5101 patients with early-stage HR-positive, HER2-negative disease to either 400 mg ribociclib with an aromatase inhibitor or to an aromatase inhibitor alone following surgery. 

Invasive disease-free survival at 36 months was 90.7% in the ribociclib arm vs 87.6% with aromatase inhibitor monotherapy (hazard ratio [HR], 0.749; P = .0006). The trial included patients with and without lymph node involvement.

At 4 years (well beyond NATALEE’s 3-year treatment window), the ribociclib group continued to do better, with an invasive disease-free survival rate of 88.5% vs 83.6% in the control arm.

Overall survival data remain immature but with a trend towards improved survival in the ribociclib arm (HR, 0.715; P < .0001), according to a recent report from the 2024 European Society for Medical Oncology Congress.

There were no new safety signals in the trial. Adverse events in the ribociclib group included neutropenia (62.5% overall; 44.3% grade 3/4), liver-related events (26.4% overall; 8.6% grade 3/4), QT prolongation (5.3% overall; 1.0% grade 3/4), and interstitial lung disease/pneumonitis (1.5% overall; 0.0% grade 3/4), according to Novartis.

Ribociclib dosing for the adjuvant indication is lower than for metastatic disease, but patients are on the same schedule — two 200 mg tablets once daily for 21 days followed by 7 days off in 28-day cycles. Treatment continues for 3 years.

Forty-two 200 mg tablets cost about $15,000, according to drugs.com. A patient assistance program is available through Novartis.

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.

Peak efficacy occurred in the range of 200-300 mg and was similar for patients with moderate or severe OSA, 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.

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.

Peak efficacy occurred in the range of 200-300 mg and was similar for patients with moderate or severe OSA, 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.

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). Dr. Sidbury, chief of the Division of Dermatology at Seattle Children’s Hospital, Seattle, highlighted two agents for AD: Lebrikizumab and nemolizumab. Lebrikizumab is a monoclonal antibody that binds to interleukin (IL)-13 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.

Whooping cough is surging in the United States, with four times as many cases reported so far this year, compared to all of 2023. 

The CDC said 14,569 cases had been reported as of Sept. 14, compared to 3475 in all of 2023. 

There were 291 new cases reported for the week ending Sept. 14, with New York having the most cases, 44, followed by Ohio, Pennsylvania, and Oklahoma with 38 each. That’s the most cases in a single week since 2015.

Whooping cough, also called pertussis, is a respiratory illness spread through coughing, sneezing, or breathing very close to another person. Babies are given the DTaP vaccine to protect against whooping cough, diphtheria, and tetanus. Because the vaccine effectiveness wanes faster for whooping cough than the two other illnesses, boosters are recommended every decade or so.
 

Why the Whooping Cough Vaccine Is Important

Whooping cough is a very contagious bacteria, so vaccination is an important step to avoid it.

But many children in their tweens aren’t getting boosters, and that age group is driving the whooping cough outbreak.

“With the increase in vaccine hesitancy that has been going on since the COVID-19 pandemic, we’re seeing outbreaks occurring in kids who are not vaccinated,” Tina Tan, MD, president-elect of the Infectious Diseases Society of America, told NBC News.

Also, people are not social distancing the way they did during the height of the COVID pandemic, when whooping cough numbers went down.

“Levels of pertussis dropped dramatically when we were all masking, and now this huge increase is getting us back to pre-pandemic levels, and probably a little above that,” Thomas Murray, MD, a Yale Medicine pediatric infectious diseases specialist, said in a news release from the school. “It’s a contagious respiratory virus that can spread fairly quickly through the population.”

FDA advisers were scheduled to meet Sept. 20 to discuss developing more effective boosters for whooping cough.
