TOPLINE:

Biosimilars demonstrate comparable drug survival and safety with adalimumab among new users, but patients switching from Humira (the originator product) to biosimilars had a 35% higher discontinuation rate than those who remained on Humira.

 

METHODOLOGY:

• Researchers conducted a cohort study using data on patients with psoriasis who were treated with adalimumab, a tumor necrosis factor alpha inhibitor used to treat moderate to severe psoriasis, from the French National Health Data System, British Association of Dermatologists Biologics and Immunomodulators Register, and Spanish Registry of Systemic Therapy in Psoriasis.
• The analysis included 7387 adalimumab-naive patients who were new users of an adalimumab biosimilar and 3654 patients (switchers) who switched from Humira to a biosimilar. Patients were matched and compared with patients receiving Humira.
• Co-primary outcomes of the study were drug discontinuation and serious adverse events.
• Researchers assessed the following adalimumab biosimilar brands: Amgevita, Imraldi, Hyrimoz, Idacio, and Hulio.

TAKEAWAY:

• All-cause drug discontinuation rates were similar between new users of biosimilars and Humira new users (hazard ratio [HR], 0.99; 95% CI, 0.94-1.04).
• Discontinuation rates were higher among those who switched from Humira to a biosimilar (HR, 1.35; 95% CI, 1.19-1.52) than among those who stayed on Humira. Switching to Amgevita (HR, 1.25; 95% CI, 1.13-1.27), Imraldi (HR, 1.53; 95% CI, 1.33-1.76), and Hyrimoz (HR, 1.80; 95% CI, 1.29-2.52) was associated with higher discontinuation rates.
• Serious adverse events were not significantly different between new users of Humira and biosimilar new users (incidence rate ratio [IRR], 0.91; 95% CI, 0.80-1.05), and between patients who switched from a biosimilar to Humira and those who stayed on Humira (IRR, 0.92; 95% CI, 0.83-1.01).
• No significant differences in discontinuation because of ineffectiveness were found between biosimilar and Humira new users (HR, 0.97; 95% CI, 0.88-1.08). Discontinuation because of adverse events was also comparable for all biosimilars among new users, except for Hyrimoz (HR, 0.54; 95% CI, 0.35-0.85), which showed fewer discontinuations than Humira.

IN PRACTICE:

“This study found comparable drug survival and safety between adalimumab biosimilars and Humira in adalimumab-naive patients, supporting the use of biosimilars as viable alternatives for new patients,” the authors wrote. However, noting that discontinuation was more likely among those who switched from Humira to a biosimilar, they added: “Changes in treatment response, skin or injection site reactions, and nocebo effects may contribute to treatment discontinuation post-switch. Thus, patients who switch from Humira to biosimilars may require closer monitoring and support to alleviate these challenges.”

The study was led by Duc Binh Phan, Dermatology Centre, Northern Care Alliance NHS Foundation Trust in Manchester, England. It was published online in The British Journal of Dermatology.

LIMITATIONS:

Unmeasured factors including psychological perceptions, regional policies, and drug availability could influence drug survival, making the results not fully reflective of treatment effectiveness or safety. Most Humira users in registries were enrolled before biosimilars became available, making it impractical to match new users on the basis of treatment initiation years. Additionally, reasons for discontinuation were not available in the French National Health Data System.

DISCLOSURES:

In the United Kingdom, the research was funded by the Psoriasis Association PhD studentship and supported by the NIHR Manchester Biomedical Research Centre. In France, the authors are employees of the French National Health Insurance, the French National Agency for the Safety of Medicines and Health Products, and the Assistance Publique — Hôpitaux de Paris and received no funding. The authors reported receiving consulting and speaker fees and clinical trial sponsorship from various pharmaceutical companies. Additional disclosures are noted in the original article.

LAS VEGAS — Onychomycosis, a stubborn fungal infection of the nail bed, is responsible for half of all nail diseases and presents a tricky challenge when it comes to both diagnosis and treatment.

According to Tracey C. Vlahovic, DPM, a professor at the Samuel Merritt University College of Podiatric Medicine, Oakland, California, most cases of onychomycosis are caused by the dermatophytes Trichophyton rubrum and T mentagrophytes, although the cause can also be a mixed infection. “Dermatophytes are going to impact the nails first, and molds may come in and join the party later,” she said at the Society of Dermatology Physician Associates (SDPA) 22nd Annual Fall Dermatology Conference.

 

“The distal subungual onychomycosis (DSO) type is still the most common, but don’t forget that onychomycosis and nail psoriasis can happen at the same time. What we can’t lose sight of is that onychomycosis is a disease of the nail bed, which ultimately affects the nail plate; it’s not a disease of the nail plate first.”

Her diagnostic approach combines periodic acid-Schiff (PAS) staining with fungal culture “because I like to know the speciation,” she said. “PAS doesn’t give me the speciation; fungal cultures should. PCR can be expensive, but that can give me speciation.”

 

How Does This Happen?

Fungal DSO occurs because of exposure to a dermatophyte, which can be as simple as tinea pedis. “Perhaps it’s the environment in the shoe,” said Vlahovic, one of the authors of a textbook on onychomycosis. “That’s something I’m always concentrating on with the patient. What is your foot hygiene like? What’s your shoe and sock wear? What’s your level of physical activity? You can have trauma to the hyponychium, where the skin and the nail meet. Maybe they trim their nails too close to the skin, or maybe there’s another skin condition like psoriasis.”

The dermatophyte, she continued, enters and invades the nail at the hyponychium and uses the keratinase enzyme to digest keratin in the nail bed. Mild inflammation develops, and pH changes cause focal parakeratosis and subungual hyperkeratosis in the form of onycholysis and subungual debris. “Hyphae then invade the lamina of the nail plate, which causes brittle nails,” she said. “The compromised hyponychium creates a reservoir for molds and bacteria.”

Therapies approved by the Food and Drug Administration (FDA) for onychomycosis include the topical agents efinaconazole, tavaborole, and ciclopirox; the oral agents terbinafine and itraconazole; and laser therapy. Off-label, Vlahovic said that she sometimes uses oral fluconazole, pulsed dosing for terbinafine, and booster doses of terbinafine or any approved oral antifungal agent. Pulse dosing for itraconazole is FDA-approved for fingernails but not for toenails.

“We don’t have any oral antifungals that are approved for children, but we do have weight-based dosing,” she noted. Other off-label treatments for onychomycosis that patients may come across while browsing the internet but do not penetrate the nail plate, include products containing tolnaftate, tree oil, and undecylenic acid, “which is a very long-chain antifungal,” Vlahovic said. “It’s so huge that it can’t get through the nail plate. These products must get through the nail plate into the nail bed where the infection is.”

According to therapeutic recommendations for the treatment of toenail onychomycosis in the United States, published in 2021, terbinafine is the primary choice for oral treatment and efinaconazole 10% for topical treatment. There are no current treatment recommendations for pregnant or lactating patients. “I always defer to the obstetrician,” said Vlahovic, a coauthor of the recommendations. For pediatric patients, there are approved topical medications: Efinaconazole and tavaborole for ages 6 and up and ciclopirox for ages 12 years or older.

Treatment recommendations for adults vary based on clinical presentation and patient characteristics. Questions to consider: Are they older? Do they have diabetes? Are they able to reach their feet to apply medication? What other medications are they taking? Are there any kidney or liver issues that are cause for concern?

Another question to consider is whether they have concurrent nail psoriasis. “When I have those patients, I often treat the onychomycosis first and the nail psoriasis second,” she said.

 

Evidence for Lasers Weak

Though laser therapy is FDA approved for the temporary increase of clear nails in onychomycosis, Vlahovic is underwhelmed by the evidence of its use for onychomycosis. According to a systematic review of 261 studies, only 1 reported treatment success as 16.7%, and clinical cures ranged from 13% to 16%. “Many of the existing studies were so poorly done in terms of protocols; it was frustrating,” she said. “No study has reported complete cure. There’s a lack of standardization across laser companies and a lack of standardization across protocols.”

Before starting oral antifungal therapy, Vlahovic uses the Onychomycosis Severity Index to determine the number of nails involved and the proportion of nails that are affected. She also wants to know if the patient is taking any medication that might interfere with an oral antifungal and gets baseline liver function tests (LFTs) to document results in the chart. “You want to discuss the pros and cons of oral antifungal therapy, and you want to set realistic expectations,” she added. “These medications are not cosmetic products; they are meant to kill fungus. Sometimes patients lose sight of that.”

Vlahovic routinely offers pulse dosing of terbinafine, which is FDA approved at a dose of 250 mg/d for 90 days. Pulse dosing involves taking terbinafine 250 mg twice a day for 1 week, followed by a 3-week break. This cycle is repeated three or four times. A clinical trial found no significant difference in outcome between patients who received pulsed vs continuous terbinafine dosing for the treatment of dermatophyte onychomycosis.

 

What About Oral Antifungal Safety?

For patients who ask about the safety of oral antifungals, Vlahovic characterized them as “well tolerated and safe in an immunocompetent population.” In a meta-analysis of 122 studies of about 22,000 patients, the pooled risk for treatment discontinuation because of adverse events was 3.4% for terbinafine 250 mg/d and 4.21% for itraconazole 200 mg/d. The risk for liver injury requiring termination of treatment and the risk of having symptomatic elevation of LFTs were less than 2% for all regimens.

According to the best available published evidence, Vlahovic said, the onychomycosis recurrence rate ranges from 6% to 40%. “That’s a wild number. We really have no idea what the true recurrence rate is, and that’s a problem.”

Vlahovic disclosed having been a consultant to and an investigator for Ortho Dermatologics and Sagis Diagnostics.

The drug survival for adalimumab is significantly higher than that of infliximab in pediatric patients with hidradenitis suppurativa (HS), results from a small single-center study showed.

A previous study found that overall drug survival of adalimumab and infliximab in adults with HS at 12 and 24 months was 56.3% and 30.5%, and 58.3% and 48.6%, respectively. “They also found that older age, longer disease duration, higher body mass index (BMI), and surgery during treatment are associated with increased drug survival,” Robyn Guo, a third-year medical student at Duke University, Durham, North Carolina, told this news organization following the annual Symposium on Hidradenitis Suppurativa Advances, where the study was presented during an oral abstract session. “To our knowledge, the drug survival of biologic therapies in pediatric HS patients has not been previously investigated.”

Adalimumab and infliximab are tumor necrosis factor blockers approved for multiple indications; adalimumab is approved for treating moderate to severe HS in patients aged 12 years or older. Infliximab is not approved for HS but is used to treat the disease.

To determine the drug survival of adalimumab and infliximab in pediatric patients with HS and whether patient comorbidities and HS lesion location are associated with length of biologic survival in pediatric patients with HS, Guo and colleagues used Kaplan-Meier survival curves to calculate biologic survival at 12 and 24 months following biologic initiation and Cox proportional hazards regression to analyze potential factors associated with biologic survival. The study population included 49 pediatric patients in the adalimumab cohort and 11 in the infliximab cohort.

The researchers found that drug survival for adalimumab was 90.6% at 12 months (95% CI, 83.0%-98.8%) and 78.3% at 24 months (95% CI, 67.7%-90.6%), while drug survival for infliximab was 54.5% at 12 months (95% CI, 31.8%-93.6%) and 36.4% at 24 months, an overall difference that reached statistical significance (P = .0009). “Our data suggests that adalimumab survival is significantly higher than infliximab survival in pediatric HS patients,” Guo said.

On univariate Cox regression analysis, gluteal HS lesions were associated with shorter adalimumab survival, and obesity was associated with longer infliximab survival.

The researchers acknowledged certain limitations of their study, including the small sample size and that unadjusted Cox regression analysis did not account for baseline HS severity, biologic therapy dosing, and concomitant medication use. Also, there were patients in both cohorts who were not biologic-naive: Two in the adalimumab cohort were previously treated with infliximab, and five patients in the infliximab cohort were previously treated with adalimumab.

“We plan on conducting further analysis using adjusted Cox regression analysis to account for baseline disease severity measured by Hurley stage, BMI, medication dosing, and concomitant medication use,” Guo said.

The researchers reported having no financial disclosures.

Recently published consensus guidelines for low-dose oral minoxidil (LDOM) treatment of hair loss provide best-practice recommendations in areas ranging from pretreatment considerations and counseling to patient monitoring. With large randomized, controlled trials lacking, the guidelines authors and other dermatologists said the paper provides practical pointers that should increase clinicians’ confidence in prescribing LDOM for hair loss.

Comfort and Confidence

Benjamin N. Ungar, MD, director of the Alopecia Center of Excellence at Mount Sinai Icahn School of Medicine, New York City, said he hopes that the guidelines will “make dermatologists in practice more comfortable with the use of low-dose oral minoxidil to treat different kinds of hair loss, and therefore, more patients will benefit.” He was not an author of the paper, which was published online in JAMA Dermatology on November 20, but was asked to comment.

Members of the multidisciplinary Low-Dose Oral Minoxidil Initiation steering committee recruited dermatologists with hair loss expertise from 12 countries. Using a modified four-round Delphi process that required at least 70% agreement, the group of 43 dermatologists crafted 76 consensus statements. “Notably,” said Co-senior author Jennifer Fu, MD, director of the Hair Disorders Clinic at the University of California, San Francisco, “27 items achieved at least 90% consensus after the first two rounds, indicating broad agreement in expert practice.”

Indications for LDOM

At least 90% of experts concurred regarding the appropriateness of LDOM use for androgenetic alopecia (AGA) and age-related thinning and in cases where topical minoxidil proves ineffective or problematic. Additional situations in which LDOM might provide direct benefit involve follicular miniaturization, such as alopecia areata, or hair cycle disruption, such as chemotherapy. The authors also recommended considering LDOM over topical minoxidil when the latter is more expensive and when patients desire enhanced hypertrichosis.

 

Contraindications and Precautions

Before prescribing LDOM, the authors wrote, clinicians may consult with primary care or cardiology when contraindications (cardiovascular issues, pregnancy/nursing, and potential drug interactions) or precautions (history of tachycardia or arrhythmia, hypotension, or impaired kidney function) exist. Patients with precautions may require blood pressure monitoring, as well as monitoring for adverse effects of treatment. The panel also suggested the latter for all patients at the time of LDOM initiation and dose escalation. The authors advised against routine baseline laboratory and EKG testing in cases without relevant precautions.

Dosing Considerations

Along with systemic adverse event risk and baseline hair loss severity, key dosing considerations include patient age, sex, and whether patients desire hypertrichosis. Consensus on daily doses for adolescent females and males begins at 0.625 mg and 1.25 mg, respectively, and ranges up to 2.5 mg for adolescent females vs 5 mg for adult females and adolescent and adult males.

Presently, said Ungar, many dermatologists — including some who prescribe LDOM — remain uncomfortable even with very low doses, perhaps because of an invalid perception of cardiovascular safety issues including potential hypotension and pericardial effusions. However, recently published data include a review published November 7 in the Journal of the American Academy of Dermatology, which showed no significant effect of LDOM on blood pressure. And in a September Journal of Drugs in Dermatology article the authors found no impact on pericardial effusions in a 100-patient cohort.

Some dermatologists worry about the impact hypertrichosis may have on patients, Ungar added. Although incidence estimates range from 15% to 30%, he said, more than half of his patients experience hypertrichosis. “However, most continue treatment because the beneficial effects outweigh the effect of hypertrichosis.”



 

Practical Roadmap

Adam Friedman, MD, who was not involved with the publication, applauds its inclusion of pragmatic clinical guidance, which he said consensus papers often lack. “This paper sets a great roadmap for working low-dose oral minoxidil into your clinical practice, Friedman, professor and chair of dermatology at George Washington University, Washington, DC, said in an interview.

Rather than limiting LDOM use to AGA, he said, the paper is most helpful in showing the spectrum of disease states for which the expert panel prescribes LDOM. “We use it as adjunctive therapy for many other things, both scarring and nonscarring hair loss,” he added.

In appropriate clinical contexts, the authors wrote, clinicians may consider combining LDOM with spironolactone or beta-blockers. Friedman said that in his hands, combining LDOM with a 5-alpha reductase inhibitor (5ARI) is “absolutely outstanding.” Minoxidil increases blood flow to the scalp, he explained, while 5ARIs prevent production of dihydrotestosterone, which miniaturizes hair.

Fu said, “We hope these consensus outcomes will be helpful to dermatology colleagues as they consider using LDOM to treat hair loss in their adult and adolescent patient populations. We anticipate that these guidelines will be updated as additional evidence-based data emerges and are encouraged that we are already seeing new publications on this topic.”

Important areas for future research, she noted, include pediatric use of LDOM, the comparative efficacy of topical vs oral minoxidil, the safety of oral minoxidil for patients with a history of allergic contact dermatitis to topical minoxidil, and the use of other off-label forms of minoxidil, such as compounded oral minoxidil and sublingual minoxidil.

The study was funded by the University of California, San Francisco, Department of Dermatology Medical Student Summer Research Fellowship Program. Fu reported personal fees from Pfizer, Eli Lilly and Company, and Sun Pharma outside of the study. The full list of author disclosures can be found in the paper. Ungar and Friedman reported no relevant financial relationships.

LAS VEGAS — When patients with rosacea consult Julie C. Harper, MD, about persistent facial erythema, she often recommends brimonidine 0.33% gel or oxymetazoline 1% cream.

These agents “work fast” and “improve redness quickly,” Harper, a dermatologist who practices in Birmingham, Alabama, said at the Society of Dermatology Physician Associates (SDPA) 22nd Annual Fall Dermatology Conference. In addition, “you’re going to know within 30 minutes or an hour whether it’s going to work or not.”

Brimonidine 0.33% gel, an alpha-2 adrenergic receptor agonist, was approved by the Food and Drug Administration (FDA) in 2014 for persistent facial erythema of rosacea. It does not treat telangiectasia and is not approved for flushing (transient erythema). Patients are advised to apply the gel daily in the morning. In phase 3 pivotal trials of patients with moderate to severe erythema of rosacea, which excluded individuals with more than two papules, a composite (investigator- and patient-reported) 2-grade improvement was seen as early as 30 minutes after application on day 1, and erythema was reduced for 9-12 hours.

Oxymetazoline 1% cream, an alpha-1a adrenergic receptor agonist, was approved by the FDA in 2017 for persistent facial erythema of rosacea. It neither treats telangiectasia nor is approved for flushing. Phase 3 trials of patients with moderate to severe persistent erythema of rosacea excluded individuals with more than three inflammatory papules or pustules. A composite (investigator- and subject-reported) 2-grade improvement was seen as early as 1 hour after application on day 1, and erythema was reduced for 9-12 hours.

 

Receptor Selectivity Differences

According to Harper, there are more reports of worsening erythema with brimonidine 0.33% gel than with oxymetazoline 1% cream, perhaps because of the different receptor selectivity between the two products. She explained that alpha-1 receptors are located only postsynaptically in vascular smooth muscle, while alpha-2 receptors are located presynaptically, which can inhibit norepinephrine and lead to vasodilation. Alpha-2 receptors are also located postsynaptically in vascular smooth muscle and in the endothelial wall, which can mediate nitric oxide release and cause vasodilation.

No head-to-head studies exist that compare brimonidine 0.33% gel with oxymetazoline 1% cream. But in a 52-week study of oxymetazoline 1% cream for persistent facial erythema associated with rosacea published in 2018, at week 52, 36.7% and 43.4% of patients achieved a 2-grade or greater composite improvement from baseline in both Clinician Erythema Assessment and Subject Self-Assessment 3 and 6 hours after a dose, respectively. Also, fewer than 1% of patients experienced a rebound effect following treatment cessation.

“What we learned from this study is that maybe patients do better if they use oxymetazoline 1% cream consistently,” Harper said. “Does that mean that everybody I give this to uses it daily? Probably not, but I think we can change the vascular tone by using it consistently every day.”

 

Oral Beta-Blockers Another Option

Alpha agonists can also help quell flushing associated with rosacea, Harper continued, but oral beta-blockers may be the better choice. In a 2020 review that drew from nine studies, researchers evaluated the use of carvedilol, propranolol, nadolol, and beta-blockers in general for rosacea-associated facial erythema and flushing. Articles studying carvedilol and propranolol showed a large reduction of erythema and flushing during treatment with a rapid onset of symptom control, while bradycardia and hypotension were the most commonly reported adverse events. “All of these agents are studied in rosacea, but none of them are FDA approved for rosacea,” Harper noted.

In a separate study, five patients with rosacea who had either severe frequent flushing episodes or persistent erythema and burning sensations were treated with carvedilol, a nonselective beta-blocker. Prior treatments included cetirizine and doxycycline, or isotretinoin combined with topical application of metronidazole gel or ivermectin without sufficient improvement in erythema. Carvedilol was added to the above treatments and titrated up to 12.5 mg twice a day and continued for at least 6 months.

The Clinician Erythema Assessment 5-point scale before therapy was 3.4 and dropped to 0.4 during therapy, while the patient self-assessment before therapy was 3.8 and dropped to 0.8 during therapy.

Another study evaluated the use of propranolol and/or doxycycline in 78 patients with rosacea. The propranolol and combination treatment groups showed more rapid improvement at weeks 4 and 8, but there was no statistically significant difference between them by week 12. Rosacea clinical scores also decreased in all groups, but there were no significant differences between them. Reduction of Assessment of Rosacea Clinical Score was 51%, 52.2%, and 57.3% in the propranolol, doxycycline, and combination groups, respectively.

Harper disclosed ties with Almirall, Cutera, Galderma, Journey, Ortho Dermatologics, and Sun Pharmaceutical Industries.

In a 2020 review that drew from nine studies, researchers evaluated the use of carvedilol, propranolol, nadolol, and beta-blockers in general for rosacea-associated facial erythema and flushing. Articles studying carvedilol and propranolol showed a large reduction of erythema and flushing during treatment with a rapid onset of symptom control, while bradycardia and hypotension were the most commonly reported adverse events. “All of these agents are studied in rosacea, but none of them are FDA approved for rosacea,” Harper noted.

In a separate study, five patients with rosacea who had either severe frequent flushing episodes or persistent erythema and burning sensations were treated with carvedilol, a nonselective beta-blocker. Prior treatments included cetirizine and doxycycline, or isotretinoin combined with topical application of metronidazole gel or ivermectin without sufficient improvement in erythema. Carvedilol was added to the above treatments and titrated up to 12.5 mg twice a day and continued for at least 6 months.

The Clinician Erythema Assessment 5-point scale before therapy was 3.4 and dropped to 0.4 during therapy, while the patient self-assessment before therapy was 3.8 and dropped to 0.8 during therapy.

Another study evaluated the use of propranolol and/or doxycycline in 78 patients with rosacea. The propranolol and combination treatment groups showed more rapid improvement at weeks 4 and 8, but there was no statistically significant difference between them by week 12. Rosacea clinical scores also decreased in all groups, but there were no significant differences between them. Reduction of Assessment of Rosacea Clinical Score was 51%, 52.2%, and 57.3% in the propranolol, doxycycline, and combination groups, respectively.

LAS VEGAS — When patients with rosacea consult Julie C. Harper, MD, about persistent facial erythema, she often recommends brimonidine 0.33% gel or oxymetazoline 1% cream.

These agents “work fast” and “improve redness quickly,” Harper, a dermatologist who practices in Birmingham, Alabama, said at the Society of Dermatology Physician Associates (SDPA) 22nd Annual Fall Dermatology Conference. In addition, “you’re going to know within 30 minutes or an hour whether it’s going to work or not.”

Brimonidine 0.33% gel, an alpha-2 adrenergic receptor agonist, was approved by the Food and Drug Administration (FDA) in 2014 for persistent facial erythema of rosacea. It does not treat telangiectasia and is not approved for flushing (transient erythema). Patients are advised to apply the gel daily in the morning. In phase 3 pivotal trials of patients with moderate to severe erythema of rosacea, which excluded individuals with more than two papules, a composite (investigator- and patient-reported) 2-grade improvement was seen as early as 30 minutes after application on day 1, and erythema was reduced for 9-12 hours.

Oxymetazoline 1% cream, an alpha-1a adrenergic receptor agonist, was approved by the FDA in 2017 for persistent facial erythema of rosacea. It neither treats telangiectasia nor is approved for flushing. Phase 3 trials of patients with moderate to severe persistent erythema of rosacea excluded individuals with more than three inflammatory papules or pustules. A composite (investigator- and subject-reported) 2-grade improvement was seen as early as 1 hour after application on day 1, and erythema was reduced for 9-12 hours.

 

Receptor Selectivity Differences

According to Harper, there are more reports of worsening erythema with brimonidine 0.33% gel than with oxymetazoline 1% cream, perhaps because of the different receptor selectivity between the two products. She explained that alpha-1 receptors are located only postsynaptically in vascular smooth muscle, while alpha-2 receptors are located presynaptically, which can inhibit norepinephrine and lead to vasodilation. Alpha-2 receptors are also located postsynaptically in vascular smooth muscle and in the endothelial wall, which can mediate nitric oxide release and cause vasodilation.

No head-to-head studies exist that compare brimonidine 0.33% gel with oxymetazoline 1% cream. But in a 52-week study of oxymetazoline 1% cream for persistent facial erythema associated with rosacea published in 2018, at week 52, 36.7% and 43.4% of patients achieved a 2-grade or greater composite improvement from baseline in both Clinician Erythema Assessment and Subject Self-Assessment 3 and 6 hours after a dose, respectively. Also, fewer than 1% of patients experienced a rebound effect following treatment cessation.

“What we learned from this study is that maybe patients do better if they use oxymetazoline 1% cream consistently,” Harper said. “Does that mean that everybody I give this to uses it daily? Probably not, but I think we can change the vascular tone by using it consistently every day.”

TOPLINE:

Levonorgestrel intrauterine devices (IUDs) are associated with significantly more reports of acne, alopecia, and hirsutism compared with copper IUDs, with some differences between the available levonorgestrel IUDs.

METHODOLOGY:

• Researchers reviewed the US Food and Drug Administration (FDA) Adverse Events Reporting System (FAERS) through December 2023 for adverse events associated with levonorgestrel IUDs where IUDs were the only suspected cause, focusing on acne, alopecia, and hirsutism.
• They included 139,348 reports for the levonorgestrel IUDs (Mirena, Liletta, Kyleena, Skyla) and 50,450 reports for the copper IUD (Paragard).

TAKEAWAY:

• Levonorgestrel IUD users showed higher odds of reporting acne (odds ratio [OR], 3.21), alopecia (OR, 5.96), and hirsutism (OR, 15.48; all P < .0001) than copper IUD users.
• The Kyleena 19.5 mg levonorgestrel IUD was associated with the highest odds of acne reports (OR, 3.42), followed by the Mirena 52 mg (OR, 3.40) and Skyla 13.5 mg (OR, 2.30) levonorgestrel IUDs (all P < .0001).
• The Mirena IUD was associated with the highest odds of alopecia and hirsutism reports (OR, 6.62 and 17.43, respectively), followed by the Kyleena (ORs, 2.90 and 8.17, respectively) and Skyla (ORs, 2.69 and 1.48, respectively) IUDs (all P < .0001).
• Reports of acne, alopecia, and hirsutism were not significantly different between the Liletta 52 mg levonorgestrel IUD and the copper IUD.

IN PRACTICE:

“Overall, we identified significant associations between levonorgestrel IUDs and androgenic cutaneous adverse events,” the authors wrote. “Counseling prior to initiation of levonorgestrel IUDs should include information on possible cutaneous AEs including acne, alopecia, and hirsutism to guide contraceptive shared decision making,” they added.

 

SOURCE:

The study was led by Lydia Cassard, Cleveland Clinic Lerner College of Medicine, Cleveland, Ohio, and was published online November 3 in Journal of the American Academy of Dermatology.

LIMITATIONS:

FAERS database reports could not be verified, and differences in FDA approval dates for IUDs could have influenced reporting rates. Moreover, a lack of data on prior medication use limits the ability to determine if these AEs are a result of changes in androgenic or antiandrogenic medication use. Cutaneous adverse events associated with copper IUDs may have been underreported because of assumptions that a nonhormonal device would not cause these adverse events.

DISCLOSURES:

The authors did not report any funding source or conflict of interests.

The US Food and Drug Administration (FDA) has approved bimekizumab, a humanized interleukin (IL)-17A and IL-17F antagonist, for the treatment of adults with moderate to severe hidradenitis suppurativa (HS).

Approval was based on results from two phase 3 studies, BE HEARD I and BE HEARD II, which found that bimekizumab improved the signs and symptoms of disease compared with placebo at week 16 and were sustained to week 48, according to a press release from UCB, the drug’s manufacturer. In both trials, a higher proportion of patients treated with bimekizumab achieved Hidradenitis Suppurativa Clinical Response (HiSCR) scores of 50 and 75 compared with those who received placebo.

The company noted that bimekizumab (Bimzelx) is the first and only approved medicine designed to selectively inhibit IL-17F in addition to IL-17A. According to the prescribing information, the recommended dosing for patients with HS is 320 mg administered by subcutaneous injection at week 0, 2, 4, 6, 8, 10, 12, 14, and 16, then every 4 weeks thereafter.

“The approval of bimekizumab for moderate-to-severe HS is tremendous news for people living with HS” and the clinicians who care for them, Jennifer L. Hsiao, MD, director of the HS clinic at the University of Southern California, Los Angeles, told this news organization.

“It is exciting that we already have two-year trial data for bimekizumab in HS and can see that bimekizumab raises the bar in terms of depth and durability of response that we can expect to see in our patients,” she added. “Given the limited treatment options for HS at this time, the addition of bimekizumab to our treatment armamentarium is a huge step forward for the HS community.”

This development marks the fifth approved indication for bimekizumab since it was first approved in October 2023 for the treatment of moderate to severe plaque psoriasis, followed by approvals for active psoriatic arthritis, nonradiographic axial spondyloarthritis, and active ankylosing spondylitis in September 2024. 

According to the prescribing information, certain adverse reactions have been observed with bimekizumab, including suicidal ideation and behavior, infections, liver biochemical abnormalities, and inflammatory bowel disease. A pregnancy exposure registry has been established that monitors pregnancy outcomes in women exposed to bimekizumab. For information, clinicians or patients can contact the Organization of Teratology Information Specialists (OTIS) Autoimmune Diseases Study at 1-877-311- 8972 or visit MotherToBaby Pregnancy Studies.

Hsiao disclosed that she is a member of the board of directors for the HS Foundation and has served as a consultant for AbbVie, Aclaris, Boehringer Ingelheim, Incyte, Novartis, Sanofi, and UCB; a speaker for AbbVie, Galderma, Novartis, Sanofi Regeneron, and UCB; and an investigator for Amgen, Boehringer Ingelheim, and Incyte.

TOPLINE:

A case series highlights the features of severe, necrotic skin wounds among hospitalized adults associated with xylazine exposure, including 9% that involved exposed deep structures such as bone or tendon.

METHODOLOGY:

• The alpha-2 agonist xylazine, a veterinary sedative, is increasingly detected in fentanyl used illicitly in the United States and may be causing necrotizing wounds in drug users.
• To characterize specific clinical features of xylazine-associated wounds, researchers conducted a case series at three academic medical hospitals in Philadelphia from April 2022 to February 2023.
• They included 29 patients with confirmed xylazine exposure and a chief complaint that was wound-related, seen as inpatients or in the emergency department.

TAKEAWAY:

• The 29 patients (mean age, 39.4 years; 52% men) had a total of 59 wounds, 90% were located on the arms and legs, and 69% were on the posterior upper or anterior lower extremities. Five wounds (9%) involved exposed deep structures such as the bone or tendon.
• Of the 57 wounds with available photographs, 60% had wound beds with predominantly devitalized tissue (eschar or slough), 11% were blisters, 9% had granulation tissue, and 21% had mixed tissue or other types of wound beds. Devitalized tissue was more commonly observed in medium or large wounds (odds ratio [OR], 5.2; P = .02) than in small wounds.
• As reported by patients, 48% were acute wounds, 20% were subacute, and 29% were chronic (present for 3 months or longer). Subacute and chronic wounds were often medium or large compared with acute wounds (OR, 48.5; P < .001) and contained devitalized tissue (OR, 9.5; P < .001).
• Of the 39 wounds with patient-reported etiology, 34 (87%) occurred at drug injection sites.

IN PRACTICE:

To the best of their knowledge, this is “the largest study of wounds among patients with confirmed exposure to xylazine and the first to systematically describe wound characteristics,” the authors wrote. The results, they concluded, “may help identify xylazine exposure and can guide research on the etiology and management of these wounds.”

SOURCE:

This study was conducted by Lydia Lutz, MD, Johns Hopkins University School of Medicine, Baltimore, Maryland, and coinvestigators and was published online in JAMA Dermatology.

LIMITATIONS:

This single-city, retrospective study limited generalizability, and the selection of the largest wounds may bias results. Additionally, chronicity data relied on patient recall, potentially introducing recall bias.

DISCLOSURES:

Two authors received support from the National Institute on Drug Abuse for the study. The authors declared no competing interests.

Two authors received support from the National Institute on Drug Abuse for the study. The authors declared no competing interests.

This article was created using several editorial tools, including AI, as part of the process. Human editors reviewed this content before publication. A version of this article first appeared on Medscape.com.

A population-based study has shown a slightly elevated risk for patients’ developing skin disorders, including alopecia areata (AA), alopecia totalis (AT), vitiligo, and bullous pemphigoid (BP), more than 6 months after COVID-19 infection. In addition, the authors reported that COVID-19 vaccination appears to reduce these risks.

The study was published in JAMA Dermatology.

 

‘Compelling Evidence’

“This well-executed study by Heo et al provides compelling evidence to support an association between COVID-19 infection and the development of subsequent autoimmune and autoinflammatory skin diseases,” wrote authors led by Lisa M. Arkin, MD, of the Department of Dermatology, University of Wisconsin School of Medicine and Public Health in Madison, in an accompanying editorial.

Using databases from Korea’s National Health Insurance Service and the Korea Disease Control and Prevention Agency, investigators led by Yeon-Woo Heo, MD, a dermatology resident at Yonsei University Wonju College of Medicine, Wonju, Republic of Korea, compared 3.1 million people who had COVID-19 with 3.8 million controls, all with at least 180 days’ follow-up through December 31, 2022.

At a mean follow-up of 287 days in both cohorts, authors found significantly elevated risks for AA and vitiligo (adjusted hazard ratio [aHR], 1.11 for both), AT (aHR, 1.24), Behçet disease (aHR, 1.45), and BP (aHR, 1.62) in the post–COVID-19 cohort. The infection also raised the risk for other conditions such as systemic lupus erythematosus (aHR, 1.14) and Crohn’s disease (aHR, 1.35).

In subgroup analyses, demographic factors were associated with diverse effects: COVID-19 infection was associated with significantly higher odds of developing AA (for both men and women), vitiligo (men), Behçet disease (men and women), Crohn’s disease (men), ulcerative colitis (men), rheumatoid arthritis (men and women), systemic lupus erythematosus (men), ankylosing spondylitis (men), AT (women), and BP (women) than controls.

Those aged under 40 years were more likely to develop AA, primary cicatricial alopecia, Behçet disease, and ulcerative colitis, while those aged 40 years or older were more likely to develop AA, AT, vitiligo, Behçet disease, Crohn’s disease, rheumatoid arthritis, systemic lupus erythematosus, Sjögren’s syndrome, ankylosing spondylitis, and BP.

Additionally, severe COVID-19 requiring intensive care unit admission was associated with a significantly increased risk for autoimmune diseases, including AA, psoriasis, BP, and sarcoidosis. By timeframe, risks for AA, AT, and psoriasis were significantly higher during the initial Delta-dominant period.

 

Vaccination Effect

Moreover, vaccinated individuals were less likely to develop AA, AT, psoriasis, Behçet disease, and various nondermatologic conditions than were those who were unvaccinated. This finding, wrote Heo and colleagues, “may provide evidence to support the hypothesis that COVID-19 vaccines can help prevent autoimmune diseases.”

“That’s the part we all need to take into our offices tomorrow,” said Brett King, MD, PhD, a Fairfield, Connecticut–based dermatologist in private practice. He was not involved with the study but was asked to comment.

Overall, King said, the study carries two main messages. “The first is that COVID-19 infection increases the likelihood of developing an autoimmune or autoinflammatory disease in a large population.” The second and very important message is that being vaccinated against COVID-19 provides protection against developing an autoimmune or autoinflammatory disease.

“My concern is that the popular media highlights the first part,” said King, “and everybody who develops alopecia areata, vitiligo, or sarcoidosis blames COVID-19. That’s not what this work says.”

The foregoing distinction is especially important during the fall and winter, he added, when people getting influenza vaccines are routinely offered COVID-19 vaccines. “Many patients have said, ‘I got the COVID vaccine and developed alopecia areata 6 months later.’ Nearly everybody who has developed a new or worsening health condition in the last almost 5 years has had the perfect fall guy — the COVID vaccine or infection.”

With virtually all patients asking if they should get an updated COVID-19 vaccine or booster, he added, many report having heard that such vaccines cause AA, vitiligo, or other diseases. “To anchor these conversations in real data and not just anecdotes from a blog or Facebook is very useful,” said King, “and now we have very good data saying that the COVID vaccine is protective against these disorders.”

George Han, MD, PhD, associate professor of dermatology at the Donald and Barbara Zucker School of Medicine at Hofstra/Northwell in Hempstead, New York, applauds investigators’ use of a large, robust database but suggests interpreting results cautiously. He was not involved with the study but was asked to comment.

“You could do a large, well-done study,” Han said, “but it could still not necessarily be generalizable. These autoimmune conditions they’re looking at have clear ethnic and racial biases.” Heo and colleagues acknowledged shortcomings including their study population’s monomorphic nature.

Additional issues that limit the study’s impact, said Han, include the difficulty of conceptualizing a 10%-20% increase in conditions that at baseline are rare. And many of the findings reflected natural patterns, he said. For instance, BP more commonly affects older people, COVID-19 notwithstanding.

Han said that for him, the study’s main value going forward is helping to explain a rash of worsening inflammatory skin disease that many dermatologists saw early in the pandemic. “We would regularly see patients who were well controlled with, for example, psoriasis or eczema. But after COVID-19 infection or a vaccine (usually mRNA-type), in some cases they would come in flaring badly.” This happened at least a dozen times during the first year of post-shutdown appointments, he said.

“We’ve seen patients who have flared multiple times — they get the booster, then flare again,” Han added. Similar patterns occurred with pyoderma gangrenosum and other inflammatory skin diseases, he said.

Given the modest effect sizes of the associations reported in the Korean study, Arkin and colleagues wrote in their JAMA Dermatology editorial that surveillance for autoimmune disease is probably not warranted without new examination findings or symptoms. “For certain,” King said, “we should not go hunting for things that aren’t obviously there.”

Rather, Arkin and colleagues wrote, the higher autoimmunity rates seen among the unvaccinated, as well as during the Delta phase (when patients were sicker and hospitalizations were more likely) and in patients requiring intensive care, suggest that “interventions that reduce disease severity could also potentially reduce long-term risk of subsequent autoimmune sequelae.”

Future research addressing whether people with preexisting autoimmune conditions are at greater risk for flares or developing new autoimmune diseases following COVID-19 infection “would help to frame an evidence-based approach for patients with autoimmune disorders who develop COVID-19 infection, including the role for antiviral treatments,” they added.

The study was supported by grants from the Research Program of the Korea Medical Institute, the Korea Health Industry Development Institute, and the National Research Foundation of Korea. Han and King reported no relevant financial relationships. Arkin disclosed receiving research grants to her institution from Amgen and Eli Lilly, personal fees from Sanofi/Regeneron for consulting, and personal consulting fees from Merck outside the submitted work. Another author reported personal consulting fees from Dexcel Pharma and Honeydew outside the submitted work. No other disclosures were reported.

The addition of dupilumab significantly reduced itching and hives, compared with placebo, in patients with chronic spontaneous urticaria (CSU) that was uncontrolled with H1-antihistamines, based on data from 151 individuals.

“Approximately 50% of patients with chronic spontaneous urticaria do not respond to antihistamines,” said Thomas B. Casale, MD, professor of internal medicine at the University of South Florida, Tampa, in an interview. Omalizumab, the only biologic approved for this condition, is not effective in all patients, and additional treatment options are needed, added Casale, the lead author who presented the new data, at the American College of Allergy, Asthma & Immunology (ACAAI) 2024 Annual Scientific Meeting.

Dupilumab (Dupixent), a fully human monoclonal antibody that targets the interleukin (IL)–4 and IL-13 pathways, is currently approved in the United States for the treatment of several allergy and dermatology indications, including atopic dermatitis, severe asthma exacerbations, chronic rhinosinusitis with nasal polyps, and prurigo nodularis.

In the study, known as LIBERTY-CSU CUPID Study C, researchers randomized 74 patients with CSU aged 6 years or older to add-on dupilumab subcutaneously every 2 weeks and 77 to placebo. (Patients were omalizumab-naive and had symptomatic CSU, despite treatment with up to four times the approved dose of standard-of-care H1-antihistamines.) Dupilumab doses were 300 mg for adults and adolescents weighing ≥ 60 kg or 200 mg for adolescents weighing < 60 kg and children weighing ≥ 30 kg.

The primary outcomes were Itch Severity Score over 7 days (ISS7; range, 0-21) and Urticaria Activity Score over 7 days (UAS7; range, 0-42).

Over the 24-week study period, patients in the dupilumab group showed significantly greater change from baseline than those in the placebo group on both measures, with least squares mean changes of 8.6 vs 6.1 for ISS7 and 15.9 vs 11.2 for UAS7 (P = .02 for both).

In addition, at 24 weeks, significantly more patients in the dupilumab group than in the placebo group achieved well-controlled disease based on a UAS of 6 or lower (41% vs 23%; P = .005). Significantly more dupilumab-treated patients also achieved a complete response (defined as a UAS of 0), compared with placebo-treated patients (30% vs 18%; P = .02).

Overall rates of treatment-emergent adverse events were 53% for both groups, and safety data were mainly consistent with dupilumab’s known safety profile, the researchers wrote.

The findings were not surprising, as a previous related study, LIBERTY-CSU CUPID Study A, showed that dupilumab was effective for CSU, Casale told this news organization. “This replicate study confirms the previous study and provides evidence for regulatory approval.”

If approved by the Food and Drug Administration (FDA), “dupilumab will provide another therapeutic option for patients with chronic urticaria unresponsive to antihistamines,” Casale commented.

No new safety signals occurred, and the ability to self-administer the medication at home provides an advantage for patients, he added. As for additional research, “analysis of patient characteristics and potential biomarkers that would predict responsiveness is needed.”

 

More Research Needed to Fine-Tune Management

An unmet need persists for patients with CSU whose disease is not adequately controlled by higher-dose H1-antihistamines, Robert G. Micheletti, MD, associate professor of dermatology and medicine at the University of Pennsylvania, Philadelphia, said in an interview. “It is important not only to identify effective add-on therapies for these patients but also to generate data to support insurance coverage and drug access,” said Micheletti, who was not involved in the study.

Also referring to the similar findings reported in the LIBERTY-CSU CUPID Study A, Micheletti said, “as in the earlier study, the results demonstrate significantly reduced itch and urticaria in treated patients compared to placebo.”

“While many providers currently prescribe dupilumab off-label for refractory CSU, FDA approval would improve access to the drug for patients who need it and provide an alternative for patients who may not be good candidates for omalizumab,” he added. However, more research is needed to define optimal management of patients with CSU with inadequate response to omalizumab.

“The LIBERTY-CSU CUPID Study B showed a small improvement in itch severity and urticaria activity among such patients receiving dupilumab,” he noted. “Future work should aim to identify biomarkers and other features predictive of response to various therapies.” 

Study B involved patients with CSU who were uncontrolled on standard-of-care antihistamines and refractory or intolerant to omalizumab, according to Regeneron. 

On November 15, after the ACAAI meeting had ended, the company announced that the FDA had accepted the resubmission of an application for approval of dupilumab for the treatment of CSU in adults and pediatric patients aged 12 years or older not adequately controlled with H1-antihistamines.

The study was supported and sponsored by Sanofi and Regeneron Pharmaceuticals. Casale disclosed serving as a consultant for ALK, ARS Pharma, AstraZeneca, Bryn Pharma, Celgene, Eli Lilly, Genentech, GSK, Jasper, Novartis, Regeneron, and Sanofi and as a speaker for Genentech and Regeneron. Micheletti had no relevant financial conflicts to disclose.

(Patients were omalizumab-naive and had symptomatic CSU, despite treatment with up to four times the approved dose of standard-of-care H1-antihistamines.) Dupilumab doses were 300 mg for adults and adolescents weighing ≥ 60 kg or 200 mg for adolescents weighing < 60 kg and children weighing ≥ 30 kg.

The primary outcomes were Itch Severity Score over 7 days (ISS7; range, 0-21) and Urticaria Activity Score over 7 days (UAS7; range, 0-42).

Over the 24-week study period, patients in the dupilumab group showed significantly greater change from baseline than those in the placebo group on both measures, with least squares mean changes of 8.6 vs 6.1 for ISS7 and 15.9 vs 11.2 for UAS7 (P = .02 for both).

In addition, at 24 weeks, significantly more patients in the dupilumab group than in the placebo group achieved well-controlled disease based on a UAS of 6 or lower (41% vs 23%; P = .005). Significantly more dupilumab-treated patients also achieved a complete response (defined as a UAS of 0), compared with placebo-treated patients (30% vs 18%; P = .02).

Overall rates of treatment-emergent adverse events were 53% for both groups, and safety data were mainly consistent with dupilumab’s known safety profile, the researchers wrote.

The findings were not surprising, as a previous related study, LIBERTY-CSU CUPID Study A, showed that dupilumab was effective for CSU, Casale told this news organization. “This replicate study confirms the previous study and provides evidence for regulatory approval.”

If approved by the Food and Drug Administration (FDA), “dupilumab will provide another therapeutic option for patients with chronic urticaria unresponsive to antihistamines,” Casale commented.

No new safety signals occurred, and the ability to self-administer the medication at home provides an advantage for patients, he added. As for additional research, “analysis of patient characteristics and potential biomarkers that would predict responsiveness is needed.”

 

More Research Needed to Fine-Tune Management

An unmet need persists for patients with CSU whose disease is not adequately controlled by higher-dose H1-antihistamines, Robert G. Micheletti, MD, associate professor of dermatology and medicine at the University of Pennsylvania, Philadelphia, said in an interview. “It is important not only to identify effective add-on therapies for these patients but also to generate data to support insurance coverage and drug access,” said Micheletti, who was not involved in the study.

Also referring to the similar findings reported in the LIBERTY-CSU CUPID Study A, Micheletti said, “as in the earlier study, the results demonstrate significantly reduced itch and urticaria in treated patients compared to placebo.”

“While many providers currently prescribe dupilumab off-label for refractory CSU, FDA approval would improve access to the drug for patients who need it and provide an alternative for patients who may not be good candidates for omalizumab,” he added. However, more research is needed to define optimal management of patients with CSU with inadequate response to omalizumab.

“The LIBERTY-CSU CUPID Study B showed a small improvement in itch severity and urticaria activity among such patients receiving dupilumab,” he noted. “Future work should aim to identify biomarkers and other features predictive of response to various therapies.” 

Study B involved patients with CSU who were uncontrolled on standard-of-care antihistamines and refractory or intolerant to omalizumab, according to Regeneron. 

On November 15, after the ACAAI meeting had ended, the company announced that the FDA had accepted the resubmission of an application for approval of dupilumab for the treatment of CSU in adults and pediatric patients aged 12 years or older not adequately controlled with H1-antihistamines.

The study was supported and sponsored by Sanofi and Regeneron Pharmaceuticals. Casale disclosed serving as a consultant for ALK, ARS Pharma, AstraZeneca, Bryn Pharma, Celgene, Eli Lilly, Genentech, GSK, Jasper, Novartis, Regeneron, and Sanofi and as a speaker for Genentech and Regeneron. Micheletti had no relevant financial conflicts to disclose.
