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.

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. Although data on the primary endpoint were disappointing, Dr. Oh suggested that the secondary outcomes support an anti-MS mechanism for the BTKi that is different from that of teriflunomide.

“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.

NEW YORK — Seborrheic dermatitis (SD) is a common and shared disorder across populations, but it is the third most common dermatologic complaint that Black individuals bring to the dermatologist and deserves more attention 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.

Dr. Kwatra

“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.

BARCELONA, SPAIN — Patients with high-risk stage III resectable melanoma treated with neoadjuvant combination immunotherapy achieved higher event- and recurrence-free survival than patients who received monotherapy 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.

NEW YORK — Because of their heterogeneity in appearance, drug-induced skin rashes are a common diagnostic challenge, but eruptions in skin of color, particularly those with a delayed onset, require a high index of suspicion 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.

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.

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.

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.

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 FDA’s Diversity Action Plan (DAP), will require plans for all pivotal and phase 3 trials to provide details in their design of how diversity will be achieved or, if there are no plans for diversity, the reason why, 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.

CHICAGO — The vast majority of women experiencing genitourinary syndrome of menopause (GSM) symptoms did not receive a prescription for hormonal vaginal therapies prior to seeking care at a specialized menopause clinic, according to research presented at the annual meeting of The Menopause Society.

“GSM symptoms are very common and affect women’s health and quality of life, often worsening without effective therapy,” Leticia Hernández Galán, PhD, of the Department of Obstetrics & Gynecology, McMaster University, Hamilton, Ontario, Canada, and colleagues reported. “We have demonstrated that most women seeking specialty care in an urban center with GSM symptoms have not been given a trial of local vaginal therapies by referring providers despite guidelines about safety and lack of contraindications. Given very long wait times for menopause providers in Canada, improved education for both women and their providers is needed to reduce needless suffering and improve care.”

Stephanie Faubion, MD, MBA, director of the Mayo Clinic Women’s Health in Jacksonville, Florida, and medical director of The Menopause Society, was not involved with the study but agreed with the authors’ assessment of the findings.

“This study highlights the treatment gap for women with genitourinary syndrome of menopause,” Dr. Faubion told this news organization. “Clearly, there is underutilization of low-dose vaginal hormonal therapies, which are known to be safe and effective. We still have work to do in terms of educating both women and providers on established treatment options for this common concern in menopausal women.” 

The findings match previous ones that found a majority of women with GSM do not receive treatment. A 2017 study, which was cited in the 2020 Menopause Society position statement on the condition, found that half of women with GSM had never used any treatment.

GSM is the current term that replaces previously used “vulvovaginal atrophy” and “atrophic vaginitis” because it encompasses all the menopause symptoms and signs associated with menopause that affect the vagina, vulva, and urinary tract. Anywhere from 50% to 84% of postmenopausal women experience GSM, the authors noted, with symptoms that include “burning, itching, or irritation of the vulva” and “lack of lubrication and discomfort or pain with sexual activity as well as dysuria, increased frequency or urgency of urination, and increased risk for urinary tract infections.”

First-line treatment of mild GSM often includes nonhormonal vaginal lubricants and moisturizers, but vaginal estrogen is considered the most effective treatment for more severe or bothersome cases. Other treatments include systematic hormone therapy and ospemifene or other selective estrogen receptor modulators.
 

Increased Risk for Urinary Tract Infections (UTIs)

Untreated GSM is not simply a quality of life issue; it increases the risk of developing serious UTIs, explained JoAnn Pinkerton, MD, a professor of obstetrics and gynecology at the University of Virginia, Charlottesville, who was not involved in the study.

“Estrogen depletion alters the vaginal epithelium, with distinct impairments in lubrication, elasticity, pH, and blood flow,” Dr. Pinkerton said. “The vaginal microbiome changes, with increasing pH following menopause and loss of lactobacillus predominance. These alterations allow a more hospitable environment for bacterial growth and increase the risk of UTI.”

Vaginal estrogen, meanwhile, reduces UTI risk because it “increases the presence of lactobacillus in the vagina due to improvements in vaginal pH, rebuilding superficial cells, elasticity, and connectivity,” she said.

The study assessed the incidence of GSM among patients at a single specialized Canadian institution, St. Joseph’s Healthcare Menopause Clinic in Hamilton, Ontario, between January 2021 and August 2024. Patients completed a Menopause Rating Scale that quantified two sets of GSM symptoms relating to “dryness of the vagina” and “bladder problems.” Patients also answered questions about the provider they had seen before coming to the specialized clinic and whether they had been prescribed local vaginal products before their visit.

Among 529 patients, the average age was 51, and the vast majority (88%) had some amount of tertiary education beyond high school. Only 21.5% were still menstruating, whereas the other respondents had stopped menstruating. The patient population was mostly White (85.6%), with Black, Hispanic, Asian, Middle Eastern, and Indigenous patients making up most of the other patient groups.

Among the 521 patients who answered the question on vaginal dryness, answers were similarly split between none (26%), mild (23%), moderate (21%), severe (15%), and very severe (15%). One third of the 526 women (34%) who answered the question on bladder problems said they had none, whereas the remainder reported their problems as mild (24%), moderate (24%), severe (11%), or very severe (7%).

Despite about half the participants reporting moderate to very severe vaginal dryness, 85% of them had not been prescribed local vaginal hormone therapies before their visit to the menopause clinic. Women were more likely to have been prescribed a localized therapy if they were older, were postmenopausal instead of perimenopausal, or had a female healthcare provider prior to this visit.

The survey also asked about the specialty and years in practice for the providers women had seen before visiting the clinic, but neither of these were predictors for receiving a hormone prescription. The patient’s education, partner status, and ethnicity were also not associated with the likelihood of a prescription.

Among 62 women who had been prescribed a vaginal hormone treatment, most were prescribed Vagifem (29%) or Premarin Vaginal cream (26%), followed by Intrarosa (19%), Estragyn cream (16%), Estring (3%), or something else (18%).
 

Serious Complications of GSM

Dr. Pinkerton described how GSM, particularly in older women, can run the risk of becoming life-threatening if untreated and unrecognized.

“For some women, UTIs can lead to urosepsis, as both the vaginal tissues and bladder tissues are thin with blood vessels close to the surface,” Dr. Pinkerton said. “What may have started as a UTI, can ascend to the kidneys or get into the bloodstream, which, in some, can develop into urosepsis, which can be life-threatening. The bacterial pathogen initiates the disease process, but host immune responses drive whether sepsis develops and its severity.”

The research by Dr. Hernández Galán was funded by the Canadian Institutes of Health Research, the Canadian Menopause Society, and Pfizer. Dr. Faubion had no disclosures, and Dr. Pinkerton has run a trial funded by Bayer and is a consultant for Bayer and Pfizer.

Patients completed a Menopause Rating Scale that quantified two sets of GSM symptoms relating to “dryness of the vagina” and “bladder problems.” Patients also answered questions about the provider they had seen before coming to the specialized clinic and whether they had been prescribed local vaginal products before their visit.

Among 529 patients, the average age was 51, and the vast majority (88%) had some amount of tertiary education beyond high school. Only 21.5% were still menstruating, whereas the other respondents had stopped menstruating. The patient population was mostly White (85.6%), with Black, Hispanic, Asian, Middle Eastern, and Indigenous patients making up most of the other patient groups.

Among the 521 patients who answered the question on vaginal dryness, answers were similarly split between none (26%), mild (23%), moderate (21%), severe (15%), and very severe (15%). One third of the 526 women (34%) who answered the question on bladder problems said they had none, whereas the remainder reported their problems as mild (24%), moderate (24%), severe (11%), or very severe (7%).

Despite about half the participants reporting moderate to very severe vaginal dryness, 85% of them had not been prescribed local vaginal hormone therapies before their visit to the menopause clinic. Women were more likely to have been prescribed a localized therapy if they were older, were postmenopausal instead of perimenopausal, or had a female healthcare provider prior to this visit.

The survey also asked about the specialty and years in practice for the providers women had seen before visiting the clinic, but neither of these were predictors for receiving a hormone prescription. The patient’s education, partner status, and ethnicity were also not associated with the likelihood of a prescription.

Among 62 women who had been prescribed a vaginal hormone treatment, most were prescribed Vagifem (29%) or Premarin Vaginal cream (26%), followed by Intrarosa (19%), Estragyn cream (16%), Estring (3%), or something else (18%).
 

Serious Complications of GSM

Dr. Pinkerton described how GSM, particularly in older women, can run the risk of becoming life-threatening if untreated and unrecognized.

“For some women, UTIs can lead to urosepsis, as both the vaginal tissues and bladder tissues are thin with blood vessels close to the surface,” Dr. Pinkerton said. “What may have started as a UTI, can ascend to the kidneys or get into the bloodstream, which, in some, can develop into urosepsis, which can be life-threatening. The bacterial pathogen initiates the disease process, but host immune responses drive whether sepsis develops and its severity.”

The research by Dr. Hernández Galán was funded by the Canadian Institutes of Health Research, the Canadian Menopause Society, and Pfizer. Dr. Faubion had no disclosures, and Dr. Pinkerton has run a trial funded by Bayer and is a consultant for Bayer and Pfizer.

CHICAGO — The vast majority of women experiencing genitourinary syndrome of menopause (GSM) symptoms did not receive a prescription for hormonal vaginal therapies prior to seeking care at a specialized menopause clinic, according to research presented at the annual meeting of The Menopause Society.

“GSM symptoms are very common and affect women’s health and quality of life, often worsening without effective therapy,” Leticia Hernández Galán, PhD, of the Department of Obstetrics & Gynecology, McMaster University, Hamilton, Ontario, Canada, and colleagues reported. “We have demonstrated that most women seeking specialty care in an urban center with GSM symptoms have not been given a trial of local vaginal therapies by referring providers despite guidelines about safety and lack of contraindications. Given very long wait times for menopause providers in Canada, improved education for both women and their providers is needed to reduce needless suffering and improve care.”

Stephanie Faubion, MD, MBA, director of the Mayo Clinic Women’s Health in Jacksonville, Florida, and medical director of The Menopause Society, was not involved with the study but agreed with the authors’ assessment of the findings.

“This study highlights the treatment gap for women with genitourinary syndrome of menopause,” Dr. Faubion told this news organization. “Clearly, there is underutilization of low-dose vaginal hormonal therapies, which are known to be safe and effective. We still have work to do in terms of educating both women and providers on established treatment options for this common concern in menopausal women.” 

The findings match previous ones that found a majority of women with GSM do not receive treatment. A 2017 study, which was cited in the 2020 Menopause Society position statement on the condition, found that half of women with GSM had never used any treatment.

GSM is the current term that replaces previously used “vulvovaginal atrophy” and “atrophic vaginitis” because it encompasses all the menopause symptoms and signs associated with menopause that affect the vagina, vulva, and urinary tract. Anywhere from 50% to 84% of postmenopausal women experience GSM, the authors noted, with symptoms that include “burning, itching, or irritation of the vulva” and “lack of lubrication and discomfort or pain with sexual activity as well as dysuria, increased frequency or urgency of urination, and increased risk for urinary tract infections.”

First-line treatment of mild GSM often includes nonhormonal vaginal lubricants and moisturizers, but vaginal estrogen is considered the most effective treatment for more severe or bothersome cases. Other treatments include systematic hormone therapy and ospemifene or other selective estrogen receptor modulators.
 

Increased Risk for Urinary Tract Infections (UTIs)

Untreated GSM is not simply a quality of life issue; it increases the risk of developing serious UTIs, explained JoAnn Pinkerton, MD, a professor of obstetrics and gynecology at the University of Virginia, Charlottesville, who was not involved in the study.

“Estrogen depletion alters the vaginal epithelium, with distinct impairments in lubrication, elasticity, pH, and blood flow,” Dr. Pinkerton said. “The vaginal microbiome changes, with increasing pH following menopause and loss of lactobacillus predominance. These alterations allow a more hospitable environment for bacterial growth and increase the risk of UTI.”

Vaginal estrogen, meanwhile, reduces UTI risk because it “increases the presence of lactobacillus in the vagina due to improvements in vaginal pH, rebuilding superficial cells, elasticity, and connectivity,” she said.

The study assessed the incidence of GSM among patients at a single specialized Canadian institution, St. Joseph’s Healthcare Menopause Clinic in Hamilton, Ontario, between January 2021 and August 2024.

CHICAGO — Less than 4% of American women aged 50-59 years use hormone therapy (HT) to treat menopausal symptoms today, approximately 10 times lower than the peak use of HT before the publication of the 2002 Women’s Health Initiative (WHI) study that misguidedly cast doubt on the safety of HT. Though subsequent research has addressed the flaws of the WHI study and supports the use of HT in most menopausal women younger than 60 years, use of this therapy has never recovered, according to research presented at the annual meeting of The Menopause Society (formerly The North American Menopause Society).

“Despite evidence supporting the efficacy and safety of HT, usage rates of US Food and Drug Administration–approved HT remain low,” Stephanie Faubion, MD, MBA, director of the Mayo Clinic Women’s Health in Jacksonville, Florida, and medical director of The Menopause Society, told attendees. “Improved education of clinicians and patients is critically needed.”

Today, “there is more clarity on the risk/benefit ratio of HT use with the benefits typically outweighing the risks in women who initiate therapy under the age of 60 years and within 10 years of menopause onset.”

Using medical and pharmacy claims data from OptumLabs, Dr. Faubion and her colleagues examined utilization rates from 2007 to 2023 of transdermal vs oral estrogen and of conjugated estrogen vs estradiol in women aged 40 years or older. The data included more than 200 million people throughout the United States covered by commercial insurance or Medicare Advantage. The researchers defined annual rate of HT use as the proportion of women who had at least 180 days of a filled prescription for a systemic HT preparation with estrogen.

The study population increased from an estimated 2 million women in 2007 to 4.5 million women in 2023, and the average age of enrollees increased from 53 in 2007 to 66 in 2023. Starting at 4.6% in 2007, HT use steadily declined to a low of 1.8% in 2023 for the whole cohort of women aged 40 years or older.

Though rates remained highest in women aged 50-64 years, it still declined within each age group: From 6% in 2007 to 3.6% in 2023 among women aged 50-54 years, from 7.3% to 3.8% among women aged 55-59 years, and from 7.5% to 2.9% among women aged 60-64 years. It also declined in younger women, from 3.2% in 2007 to 1.5% in 2023 in those aged 45-50 years. Estradiol was the most common formulation used, and oral administration was the most common route.

The researchers also saw a gradual decline during the study period in the use of high-dose oral HT and an increase in the use of low-dose oral HT, whereas standard dosages remained fairly consistent as the most common dose prescribed. Similarly, the use of high transdermal doses declined, whereas low transdermal doses increased and surpassed the use of standard doses. Conjugated estrogen use plummeted during the study period across all age groups, from 2%-5% in most age groups to < 1% in all age groups by 2023.

One limitation of the study was that it could not examine rates of compounded HT use because those would not be reflected in insurance claims, pointed out JoAnn Pinkerton, MD, a professor of ob.gyn. at the University of Virginia in Charlottesville, Virginia, who was not involved in the study. Dr. Pinkerton found it surprising that the numbers were so low, despite the fact that research estimates suggest less than 15% of menopausal women are receiving adequate treatment, she told this news organization. “You can see there’s a large unmet need to get treatment,” she said. “All major medical societies say the same thing: For healthy, symptomatic menopausal women, you can use hormone therapy safely and effectively.” 

The lack of education among providers is likely the biggest reason for the decline, Dr. Pinkerton says. “I think it’s because there’s a whole group of providers that did not receive any training, and that’s OB/GYNs, internal medicine, family practice, endocrinologists,” she said. “Now that people are starting to feel more confident that we can use it safely, we’re trying to get that training out to people about vasomotor symptoms, about hormone therapy, and now about new nonhormone therapies.”

Dr. Pinkerton noted that The Menopause Society has begun a new teaching program, Menopause Step-by-Step, aimed at providing short articles on the basics of menopause, HT, non-HT, and vaginal issues.

A separate poster presented at the conference provides insight into another potential factor contributing to low HT rates. A survey of 1050 American and Canadian women found that 90% discussed their symptoms with their healthcare providers, yet only 25% said their doctor identified the symptoms as likely due to perimenopause or menopause on their first visit — and only 10% of respondents said their doctor was the one to bring up perimenopause/menopause.

The respondents comprised a convenience sample of those who saw the survey on social media, in an email, or on the website of Morphus, a Toronto-based company aimed at providing support, information, and products related to menopause. Though the survey is ongoing, the analyzed responses are from March to May 2024.

Though 40% of the women said their provider attributed their symptoms to perimenopause or menopause on the second or third visit, 18% saw a provider four to five times, and 17% saw a provider more than five times before the provider considered menopause as a cause. About a third of the women (35%) brought it up to their doctor themselves and found their provider receptive, but 40% said the response was dismissive when they brought it up, and 15% said the topic was never broached at all.

Andrea Donsky, RHN, founder of Morphus who conducted the study, found these numbers surprising because she would have hoped that more doctors would have brought up perimenopause/menopause sooner. “We still have a lot of work to do to help educate women and healthcare providers,” Ms. Donsky told this news organization. “A lot of women spend years not knowing they’re in this phase of life, so they visit their doctors/HCPs [healthcare providers] many times because the connection isn’t made on the first visit.”

Danielle Meitiv, MS, a study co-author and health coach based in Silver Spring, Maryland, added, “Everyone wonders why we end up with Dr. Google; that’s the only doctor who’s talking to us about menopause.”

Dr. Pinkerton was less surprised by these survey findings. “As a menopause specialist, my most common new patient is a perimenopausal woman who feels like she hasn’t been listened to,” whether it’s her primary care doctor, her ob.gyn., or another clinician. “If the provider doesn’t ask or if the women doesn’t tell, then you don’t have the conversation,” Dr. Pinkerton said. “So many women in perimenopause are busy with work, families, partnerships, aging parents — all of the issues that they’re dealing with — that when they start to have sleep issues or mood issues or easy crying, they relate it to their life stressors, instead of recognizing that it’s fluctuating hormones.”

When Ms. Donsky examined the 1223 responses they had received through August 2024, the most common treatments advised for symptoms were antidepressants and HT, both recommended by 38% of providers. Other common recommendations were to “lose weight,” “eat less and exercise more,” supplements, or birth control pills.

Dr. Faubion had no disclosures, and her study used no external funding. Dr. Pinkerton has run a trial funded by Bayer and is a consultant for Bayer and Pfizer. Ms. Donsky is the owner of Morphus. Ms. Meitiv had no disclosures. The poster on women’s experiences with providers was funded by Morphus Inc.

The Veterans Health Administration (VHA) provides care for about 10,000 transgender women, and clinicians must understand their distinctive needs for prostate cancer screening, a urologist told cancer specialists during a presentation at the 2024 annual meeting of the Association of VA Hematology/Oncology in Atlanta.

Even if they’ve undergone gender reassignment surgery, “all transgender women still have a prostate, so therefore they remain at risk of prostate cancer and could still be considered for prostate cancer screening,” said Farnoosh Nik-Ahd, MD, a resident physician at the University of California San Francisco. However, “clinicians and patients may not be aware of prostate cancer risk, so that they may not think [of screening] transgender women.”

Nik-Ahd also noted another complication: The results of prostate screening tests may be misleading in this population.

Transgender women were born biologically male but now identify as female. These individuals may have undergone gender reassignment surgery to remove male genitalia, but the procedures do not remove the prostate. They also might be taking estrogen therapy. “Prostate cancer is a hormonally driven cancer, and the exact impact of gender-affirming hormones on prostate cancer risk and development is unknown,” Nik-Ahd said.

In a 2023 study in JAMA, Nik-Ahd and colleagues identified 155 cases of prostate cancer in transgender women within the VHA (about 14 cases per year) from 2000 to 2022. Of these patients, 116 had never used estrogen, while 17 had used it previously and 22 used it at diagnosis.

The median age of patients was 61 years, 88% identified as White, and the median prostate-specific antigen (PSA) was 6.8 ng/mL. “Given estimates of 10,000 transgender women in the US Department of Veterans Affairs, 33 cases per year would be expected. Instead, only about 14 per year were observed,” the researchers wrote. “Lower rates may stem from less PSA screening owing to barriers including lack of prostate cancer risk awareness or stigma, the suppressive effects of estrogen on prostate cancer development, or prostate cancers being missed in transgender women because of misinterpretation of ‘normal’ PSA levels among those receiving gender-affirming hormone therapies.”

In the presentation, Nik-Ahd said, “PSA density, which is a marker of prostate cancer aggressiveness, was highest in transgender women who were actively on estrogen.”

She noted, “the existing thyrotropin reference ranges, which is what we use to interpret PSA values, are all based on data from cisgender men.” The ranges would be expected to be far lower in transgender women who are taking estrogen, potentially throwing off screening tests, she said, and “ultimately missing clinically significant prostate cancer.”

In the larger picture, there are no specific guidelines about PSA screening in transgender women, she said. 

A recent study published in JAMA by Nik-Ahd and colleagues examined PSA levels in 210 transgender women (mean age 60 years) treated within the VHA from 2000 to 2023. All were aged 40 to 80 years, had received estrogen for at least 6 months (mean duration 4.7 years), and didn’t have prostate cancer diagnoses.

“Median (IQR) PSA was 0.02 (0-0.2) ng/mL and the 95th percentile value was 0.6 ng/mL,” the report found. “PSAs were undetectable in 36% of patients (23% and 49% of PSAs in patients without and with orchiectomy, respectively).”

The researchers write that “the historic cut point of 4 ng/mL, often used as a threshold for further evaluation, is likely far too high a threshold for this population.”

Nik-Ahd noted, “clinicians should interpret PSA values in transgender women on estrogen with extreme caution. In this population, normal might actually not be normal, and a value that is considered normal might be very abnormal for somebody who is on estrogen. If you're unsure of whether a PSA value is appropriate for a transgender woman on estrogen, refer that patient to a urologist so they can undergo further evaluation.”

The Veterans Health Administration (VHA) provides care for about 10,000 transgender women, and clinicians must understand their distinctive needs for prostate cancer screening, a urologist told cancer specialists during a presentation at the 2024 annual meeting of the Association of VA Hematology/Oncology in Atlanta.

Even if they’ve undergone gender reassignment surgery, “all transgender women still have a prostate, so therefore they remain at risk of prostate cancer and could still be considered for prostate cancer screening,” said Farnoosh Nik-Ahd, MD, a resident physician at the University of California San Francisco. However, “clinicians and patients may not be aware of prostate cancer risk, so that they may not think [of screening] transgender women.”

Nik-Ahd also noted another complication: The results of prostate screening tests may be misleading in this population.

Transgender women were born biologically male but now identify as female. These individuals may have undergone gender reassignment surgery to remove male genitalia, but the procedures do not remove the prostate. They also might be taking estrogen therapy. “Prostate cancer is a hormonally driven cancer, and the exact impact of gender-affirming hormones on prostate cancer risk and development is unknown,” Nik-Ahd said.

COPENHAGEN — High-dose oral cholecalciferol (vitamin D3) supplementation significantly reduces evidence of disease activity in patients with clinically isolated syndrome (CIS), results of a randomized, controlled trial suggest. In addition, cholecalciferol had a favorable safety profile and was well tolerated.

“These data support high-dose vitamin D supplementation in early MS and make vitamin D the best candidate for add-on therapy evaluation in the therapeutic strategy for multiple sclerosis [MS],” said study author Eric Thouvenot, MD, PhD, University Hospital of Nimes, Neurology Department, Nimes, France.

The study was presented at the 2024 ECTRIMS annual meeting.
 

Vitamin D Supplementation Versus Placebo

Research shows vitamin D deficiency is a risk factor for MS. However, results of previous research investigating vitamin D supplementation in MS, with different regimens and durations, have been contradictory.

The current double-blind study included 303 adults newly diagnosed with CIS (within 90 days) and a serum 25-hydroxy vitamin D concentration of less than 100 nmol/L at baseline. Participants had a median age of 34 years, and 70% were women.

About one third of participants had optic neuritis, two thirds had oligoclonal bands from cerebrospinal fluid analysis, and the median Expanded Disability Status Scale (EDSS) score was 1.0. Of the total, 89% fulfilled 2017 McDonald criteria for the diagnosis of relapsing-remitting MS (RRMS).

Participants were randomly assigned to receive high-dose (100,000 international units) oral cholecalciferol or placebo every 2 weeks for 24 months. Participants had a clinical visit at 3, 6, 12, 18, and 24 months, and brain and spinal cord MRI with and without gadolinium at 3, 12, and 24 months.

The primary outcome was occurrence of disease activity — relapse, new or enlarging T2 lesions, and presence of contrast-enhancing lesions.
 

Significant Difference

During follow-up, 60.3% in the vitamin group showed evidence of disease activity versus 74.1% in the placebo group (hazard ratio [HR], 0.66; 95% CI, 0.50-0.87; P = .004). In addition, the median time to evidence of disease activity was 432 days in the vitamin D group versus 224 days in the placebo group (P = .003).

“As you can see, the difference is really, really significant,” said Dr. Thouvenot, referring to a Kaplan-Meier curve. He said he was somewhat surprised by the “very rapid” effect of vitamin D.

He noted that the 34% reduction in relative risk for disease activity is “similar to that of some published platform therapies for CIS patients.”

An analysis of the 247 patients who met 2017 McDonald criteria for RRMS at baseline showed the same results.

Secondary analyses showed no significant reduction in relapses and no significant differences for annual change in EDSS, quality of life, fatigue, anxiety, or depression.

Additional analyses showed the HR was unchanged after adjusting for known prognostic factors including age, sex, number of lesions (< 9 vs ≥ 9), EDSS score at baseline, and delay between CIS and treatment onset.

Results showed vitamin D3 supplementation was safe and well tolerated. Dr. Thouvenot noted that 95% of participants completed the trial, and none of the 33 severe adverse events in 30 patients suggested hypercalcemia or were related to the study drug.

These encouraging new data support further studies of high-dose vitamin D supplementation as an add-on therapy in early MS, said Dr. Thouvenot. He noted that animal models suggest vitamin D added to interferon beta has a synergistic effect on the immune system.
 

‘Fabulous’ Research

During a question-and-answer session, delegates praised the study, with some describing it as “fantastic” or “fabulous.”

Addressing a query about why this study succeeded in showing the benefits of vitamin D while numerous previous studies did not, Dr. Thouvenot said it may be due to the longer duration or a design that was better powered to show differences.

Asked if researchers examined vitamin D blood levels during the study, Dr. Thouvenot said these measures are “ongoing.”

Responding to a question of whether high-dose vitamin D could be a lifelong treatment, he referred again to the “excellent” safety of the intervention. Not only is it well tolerated, but vitamin D benefits bones and the risk for hypercalcemia is low except perhaps for patients with tuberculosis or sarcoidosis, he said.

“When you exclude those patients, the safety is huge, so I don’t know why we should stop it once it’s started.”

This study was funded in part by the French Ministry of Health. Dr. Thouvenot reported no relevant disclosures.
