Safety data spanning up to 5 years from clinical trials of adolescents and adults using 15 mg or 30 mg of upadacitinib to treat moderate to severe atopic dermatitis (AD) indicates that rates of treatment-emergent adverse events remained low and consistent, with no new safety risks identified, underscoring the medication’s stable safety profile over an extended duration.

Those are among the key findings from an integrated analysis of long-term upadacitinib use presented by Christopher G. Bunick, MD, PhD, during a late-breaking abstract session at the Revolutionizing Atopic Dermatitis Virtual Conference. Upadacitinib (Rinvoq) is an oral Janus kinase (JAK) inhibitor, approved by the Food and Drug Administration for adults and pediatric patients aged 12 years of age and older with refractory, moderate to severe AD in January 2022.

“What makes this study special is that these patients are followed for 260 weeks, or 5 years, and it encompasses over 7,000 patient-years of exposure,” said Dr. Bunick, associate professor of dermatology at Yale University, New Haven, Connecticut. “This is a milestone because it’s the longest safety study ever published for any systemic drug for AD.”

He and his colleagues evaluated the safety data for up to 5 years of upadacitinib 15 mg and 30 mg use in adolescents and adults with moderate to severe AD, based on the results of integrated data from three ongoing global multicenter phase 3 trials: Measure Up 1, Measure Up 2, and AD Up. Patients in the trials were randomized 1:1:1 to receive oral upadacitinib 15 mg, upadacitinib 30 mg, or placebo once daily alone (Measure Up 1 and 2) or with concomitant topical corticosteroids (AD Up). At week 16, patients receiving 15 mg or 30 mg upadacitinib during the double-blind period continued their assigned treatment in the blinded extension (BE) period, whereas patients receiving placebo were randomized 1:1 to receive either 15 mg or 30 mg upadacitinib in the BE period. The integrated analysis included 2683 patients (529 adolescents and 2154 adults) who received at least one dose of upadacitinib. Of these, 1337 received the 15-mg dose, while 1346 received the 30-mg dose. The researchers analyzed treatment-emergent events of special interest as exposure-adjusted rates per 100 patient-years (PY) for the entire treatment period to adjust for potentially different follow-up durations.

According to Dr. Bunick, researchers often refer to “100 patient-years” in safety analyses to measure how common certain events are. “It is a straightforward way to convey the collective experience of the study’s participants over time,” he told this news organization. “For instance, if 100 patients are each monitored for 1 year, or 50 patients for 2 years each, both scenarios amount to 100 patient-years. This metric allows clinicians to understand how often certain adverse events occur across a diverse group over a specific time frame, providing a clear picture of long-term safety.”

Upadacitinib trials in atopic dermatitis have included diverse patient groups with varying risk factors. “Patients were not cherry-picked,” he said. “What I mean by that is that about 50% of patients enrolled in these trials had, at baseline, at least one cardiovascular risk factor: about 30% used tobacco; 10% had hypertension, and 5% had a history of a cardiovascular event.” In addition, about 15% were over age 50 with one cardiovascular risk factor and about 20% had a body mass index (BMI) greater than 30 kg/m². Among women in the study, about 20% were on oral contraceptives, yet none developed a venous thromboembolism (VTE).

In the integrated analysis, the rate of treatment-emergent adverse events that led to discontinuation of upadacitinib was about 4.2 events per 100 PY, “meaning that this medicine shows durability,” Dr. Bunick said. “Very few people are discontinuing due to adverse events.”

Serious and opportunistic infections ranged from 1.6 to 2.8 events per 100 PY, but these were stable across the 1- to 5-year time points. The rates of active TB were less than 0.1 per 100 PY, while the rates of herpes zoster ranged from 3.5 to 5.5 events per 100 PY. “The key take-home point here is that 5% or less of the patients at baseline had received the shingles vaccine, so it’s very important to talk to patients about receiving the shingles vaccine before they go on upadacitinib,” Dr. Bunick advised, because “this could reduce risk of herpes zoster occurring in upadacitinib-treated patients substantially.”

In other findings, incidence rates of nonmelanoma skin cancer (NMSC) ranged between 0.3 and 0.4 per 100 PY, while the rate of malignancy excluding NMSC ranged between 0.3 and 0.4 per 100 PY. Meanwhile, the rates of gastrointestinal perforations and VTE stood at 0.1 per 100 PY or lower, and MACE incidence rates ranged from 0.1 to 0.2 per 100 PY.

During his presentation, Dr. Bunick compared findings related to malignancy (excluding NMSC), MACE, and VTE to other published real-world background rates observed in moderate to severe AD populations. He noted that, while the malignancy rate in the current trial ranged from 0.3 to 0.4 per 100 PY, an observational study of more than 66,000 AD patients in the United Kingdom reported a malignancy (excluding NMSC) background incidence rate of 0.33 per 100 PY, and SEER data estimate that the malignancy incidence rate in the US general population is 0.45 per 100 PY. “Therefore, patients on upadacitinib at the 5-year mark are right at the AD population baseline risk,” he said.

And while the incidence rate of MACE in the current trial ranged from less than 0.1 to 0.2 per 100 PY, the background incidence rate of MACE in a Danish observational study of more than 2,500 patients with moderate to severe AD was 0.63 per 100 PY. “This suggests that there may be an anti-inflammatory and even a cardiovascular protective effect for patients on upadacitinib,” Dr. Bunick said.

As for VTE, the incidence rate in the current trial was 0.1 per 100 PY, but VTE background incidence rate observed in a moderate to severe AD population in the United States is 0.31 per 100 PY. “Again, this suggests anti-inflammatory and cardiovascular protective effects of upadacitinib in AD patients at the 5-year mark,” he said. “Reporting of MACE, VTE, and malignancy (excluding NMSC) in upadacitinib phase 3 clinical trials for AD generally reflects the background observations of these events in the AD population.”

He acknowledged certain limitations of the study, including the fact that observational data may overestimate the risk of adverse events.

Discussing the incidence rates for MACE, VTE, and malignancy in upadacitinib AD trials, Dr. Bunick remarked, “these are rock-bottom rates that have been low through 5 years of treatment.”

Dr. Bunick disclosed that he has received grant or research support from AbbVie (the manufacturer of upadacitinib), Almirall, Ortho Dermatologics, Timber, and Palvella. He is also a consultant and/or an adviser to AbbVie, Almirall, Apogee, Connect Bropharma, Arcutis, Eli Lilly, Novartis, Pfizer, Sanofi-Regeneron, Ortho Dermatologics, Leo Pharma, and UCB.

The prevalence of clinically meaningful conjunctivitis in patients taking dupilumab for atopic dermatitis (AD) is likely about 2%, and it most often occurs in the first 16 weeks of therapy.

Those are key findings from an analysis of published trials of dupilumab for AD and other conditions that study author Matthew Zirwas, MD, presented during a late-breaking abstract session at the Revolutionizing Atopic Dermatitis (RAD) Virtual Conference.

Adults with AD have a significant and disease severity–dependent increased risk of developing ocular surface diseases, including conjunctivitis and keratitis, compared with the general population and independent of any drug effect, according to Dr. Zirwas, a dermatologist with Probity Medical Research of Columbus, Ohio.

Dupilumab inhibits signaling of interleukin (IL)-4 and IL-13, which drive type 2 inflammatory diseases such as AD, asthma, chronic rhinosinusitis with nasal polyposis (CRSwNP), eosinophilic esophagitis (EoE), prurigo nodularis (PN), and chronic spontaneous urticaria (CSU).

In randomized, placebo-controlled trials of dupilumab in patients with moderate to severe AD, conjunctivitis was reported in more patients who received dupilumab treatment than in placebo-treated patients.

“When it comes to dupilumab-induced conjunctivitis, we have a good idea of the etiology, but the question of how frequently it occurs versus how frequently the conjunctivitis is unrelated to dupilumab is an interesting one,” he said. “How often is it clinically meaningful? What is it that is so unique about AD patients? We’ve all heard that it is a unique adverse event that only happens to people with AD and not to people using dupilumab for other indications. Where it gets interesting to me is how do we differentiate the cases that are dupilumab induced versus the cases that are just part of the underlying AD process?”

For their analysis, Dr. Zirwas and co-authors reviewed the incidence of conjunctivitis adverse events in patients from 15 completed, randomized, double-blind placebo-controlled trials evaluating dupilumab in AD, asthma, CRSwNP, EoE, PN, and CSU, along with the severity and resolution of conjunctivitis events in adults with AD.

Of the 15 trials, 7 were conducted in patients with AD: 4 in adults, 1 in adolescents, 1 in school-aged children, and 1 in preschoolers. One of the AD trials, LIBERTY AD CHRONOS, extends 52 weeks. The remaining eight trials of patients with asthma, CRSwNP, EoE, PN, and CSU lasted 24-52 weeks.

In the non-AD trials, the researchers observed that conjunctivitis rates were generally in the 1%-3% range, with less pronounced or no differences between the dupilumab and placebo groups. In the AD trials, conjunctivitis rates were higher in patients receiving dupilumab, compared with those receiving placebo across age groups.

In the 16-week SOLO 1 & 2 and AD-1021 monotherapy trials, 12 conjunctivitis events occurred in 517 patients who received placebo (2%), compared with 103 of 1047 patients (9.84%) who received dupilumab. Of the dupilumab-associated conjunctivitis cases, 80 (78%) patients recovered by the end of the trials. Of the 23 cases of conjunctivitis that did not recover or dropped out of the trial, 15 were among the 529 patients who received 300 mg dupilumab once every 2 weeks (q2w) (3%) and eight were among the 518 who received 300 mg dupilumab once weekly (qw) (2%).

In the 52-week LIBERTY AD CHRONOS trial, 29 conjunctivitis events occurred in 315 patients who received placebo plus topical corticosteroid (TCS) (9%), compared with 113 of 425 patients (27%) who received dupilumab plus TCS. Of these, 103 (91%) recovered by the end of the trial. Of the 11 patients with conjunctivitis who did not recover or dropped out of the trial, 3 were among the 110 patients who received 300 mg dupilumab q2w plus TCS (3%), and 8 were among the 315 who received 300 mg dupilumab qw plus TCS (3%).

“When I look at all of this data, I think that about 2% of people treated with dupilumab are going to get clinically very meaningful conjunctivitis that may be therapy limiting,” Dr. Zirwas concluded. “The vast majority of those cases appear to happen in the first 16 weeks. This is just not something we see in cases of patients treated with dupilumab treated for other reasons.”

Following his presentation, a meeting attendee asked Dr. Zirwas if conjunctivitis occurs more often in patients with facial dermatitis. “My perception is that it happens more often in people who have facial or eyelid dermatitis, but I’ve seen it in plenty of people who didn’t have any facial or eyelid dermatitis,” he said. “I have seen more conjunctivitis in people with more severe AD and more severe atopic comorbidities. That is anecdotal. The data that I have seen has been back and forth on this topic.”

Dr. Zirwas disclosed that he is a speaker and consultant for Sanofi, Regeneron, Leo, Lilly, Galderma, Pfizer, and AbbVie. Several of his co-authors work for Regeneron Pharmaceuticals.

Dupilumab inhibits signaling of interleukin (IL)-4 and IL-13, which drive type 2 inflammatory diseases such as AD, asthma, chronic rhinosinusitis with nasal polyposis (CRSwNP), eosinophilic esophagitis (EoE), prurigo nodularis (PN), and chronic spontaneous urticaria (CSU).

In randomized, placebo-controlled trials of dupilumab in patients with moderate to severe AD, conjunctivitis was reported in more patients who received dupilumab treatment than in placebo-treated patients.

“When it comes to dupilumab-induced conjunctivitis, we have a good idea of the etiology, but the question of how frequently it occurs versus how frequently the conjunctivitis is unrelated to dupilumab is an interesting one,” he said. “How often is it clinically meaningful? What is it that is so unique about AD patients? We’ve all heard that it is a unique adverse event that only happens to people with AD and not to people using dupilumab for other indications. Where it gets interesting to me is how do we differentiate the cases that are dupilumab induced versus the cases that are just part of the underlying AD process?”

For their analysis, Dr. Zirwas and co-authors reviewed the incidence of conjunctivitis adverse events in patients from 15 completed, randomized, double-blind placebo-controlled trials evaluating dupilumab in AD, asthma, CRSwNP, EoE, PN, and CSU, along with the severity and resolution of conjunctivitis events in adults with AD.

Of the 15 trials, 7 were conducted in patients with AD: 4 in adults, 1 in adolescents, 1 in school-aged children, and 1 in preschoolers. One of the AD trials, LIBERTY AD CHRONOS, extends 52 weeks. The remaining eight trials of patients with asthma, CRSwNP, EoE, PN, and CSU lasted 24-52 weeks.

In the non-AD trials, the researchers observed that conjunctivitis rates were generally in the 1%-3% range, with less pronounced or no differences between the dupilumab and placebo groups. In the AD trials, conjunctivitis rates were higher in patients receiving dupilumab, compared with those receiving placebo across age groups.

In the 16-week SOLO 1 & 2 and AD-1021 monotherapy trials, 12 conjunctivitis events occurred in 517 patients who received placebo (2%), compared with 103 of 1047 patients (9.84%) who received dupilumab. Of the dupilumab-associated conjunctivitis cases, 80 (78%) patients recovered by the end of the trials. Of the 23 cases of conjunctivitis that did not recover or dropped out of the trial, 15 were among the 529 patients who received 300 mg dupilumab once every 2 weeks (q2w) (3%) and eight were among the 518 who received 300 mg dupilumab once weekly (qw) (2%).

In the 52-week LIBERTY AD CHRONOS trial, 29 conjunctivitis events occurred in 315 patients who received placebo plus topical corticosteroid (TCS) (9%), compared with 113 of 425 patients (27%) who received dupilumab plus TCS. Of these, 103 (91%) recovered by the end of the trial. Of the 11 patients with conjunctivitis who did not recover or dropped out of the trial, 3 were among the 110 patients who received 300 mg dupilumab q2w plus TCS (3%), and 8 were among the 315 who received 300 mg dupilumab qw plus TCS (3%).

“When I look at all of this data, I think that about 2% of people treated with dupilumab are going to get clinically very meaningful conjunctivitis that may be therapy limiting,” Dr. Zirwas concluded. “The vast majority of those cases appear to happen in the first 16 weeks. This is just not something we see in cases of patients treated with dupilumab treated for other reasons.”

Following his presentation, a meeting attendee asked Dr. Zirwas if conjunctivitis occurs more often in patients with facial dermatitis. “My perception is that it happens more often in people who have facial or eyelid dermatitis, but I’ve seen it in plenty of people who didn’t have any facial or eyelid dermatitis,” he said. “I have seen more conjunctivitis in people with more severe AD and more severe atopic comorbidities. That is anecdotal. The data that I have seen has been back and forth on this topic.”

Dr. Zirwas disclosed that he is a speaker and consultant for Sanofi, Regeneron, Leo, Lilly, Galderma, Pfizer, and AbbVie. Several of his co-authors work for Regeneron Pharmaceuticals.

Among patients with moderate-to-severe atopic dermatitis (AD) treated with the oral Janus kinase inhibitor upadacitinib for 4 or more weeks, more than half achieved clear or almost clear skin and 45% or more reported no or minimal itch, results from an analysis of registry data showed.

“We know from clinical trials that upadacitinib is effective, but we have very little real-world experience on its effectiveness,” presenting study author Melinda Gooderham, MD, medical director of the Skin Center for Dermatology in Peterborough, Ontario, Canada, said during a late-breaking abstract session at the Revolutionizing Atopic Dermatitis (RAD) Virtual Conference.

For the analysis, she and her coauthors evaluated the real-world clinical and patient-reported outcomes of 335 adults enrolled in the CorEvitas AD Registry from July 21, 2020, through Aug. 7, 2023. They included patients who were on upadacitinib for at least 4 weeks and persisted on the drug until the time of evaluation.

The CorEvitas AD Registry is a prospective, non-interventional registry of adults diagnosed with AD by a dermatologist or qualified dermatology practitioner. Outcomes measures included the proportion of patients who achieved skin clearance as defined by a Validated Investigators Global Assessment Scale for Atopic Dermatitis (vIGA) score of 0 or 1, an Eczema Area and Severity Index (EASI) score of 3 or less, a Peak Pruritus Numeric Rating Scale (PP-NRS) score of 0 or 1, Patient-Oriented Eczema Measure (POEM) scores of 0-2, Dermatology Life Quality Index (DLQI) scores of 0 or 1, or an Atopic Dermatitis Control Tool (ADCT) score of <7.

The researchers evaluated cross-sectional data from three different cohorts: data from the last registry visit (the overall cohort), data from a visit within 1 month to less than 5 months of upadacitinib initiation (the 1-5 months cohort), and data from a visit within 5-9 months following upadacitinib initiation (the 5-9 months cohort). They also conducted subgroup analyses of patients with prior use of biologics for AD (bio-experience) and those with no such history (bio-naive). Safety events were not assessed in this analysis.

The mean age of the 335 patients was 45.6 years, 51.6% were female, 64.2% were White, 64.2% were based in the United States and the rest were based in Canada. Most patients (70.8%) were treated with the 15-mg dose of upadacitinib. The median duration of treatment was 6.9 months. Slightly more than one-quarter of patients (28.1%) reported concomitant use of topical corticosteroids for AD, while 45.4% reported prior use of dupilumab and 6% reported prior use of tralokinumab.

Dr. Gooderham reported that 57.5% of patients in the total cohort total cohort achieved clear or almost clear skin (a vIGA-AD score of 0 or 1), with slight differences between the bio-naive (60.6%) and bio-experienced (54.1%) subgroups.

The other outcomes were similarly close between the 176 bio-naive and 159 bio-experienced patients. Specifically, 74.8% in the total cohort, 79.4% in the bio-naive subgroup, and 69.6% in the bio-experienced subgroup achieved an EASI score of 3 or less. In the measure of the worst itch in the past 24 hours, 45.3%, 47.7%, and 42.8% respectively achieved a PP-NRS of 0 or 1. In the patient-reported disease burden, 36.4%, 41%, and 31.4% achieved a POEM score of 0-2. In the quality of life measure, 39.8%, 42.8%, and 36.5% achieved a DLQI score of 0 or 1. In the measure of disease control, 69.3%, 70.5%, and 67.9% achieved an ADCT score of <7. In a combination of skin clearance and itch control, 40.9%, 43.2%, and 38.4% of the total cohort, bio-naive, and bio-experienced respectively achieved both an EASI score of 3 or less and a PP-NRS of 0 or 1.

The study outcomes were similar between the 1-5 months cohort and the 5-9 months cohort, but there was a trend toward more clearance the longer patients were on therapy.

“The findings suggest that low levels of disease severity are observed in patients on upadacitinib in a real-world setting,” Dr. Gooderham concluded. “This confirms what we see in the clinical trials.”

She disclosed that she is a consultant to, a speaker for, and/or a member of the advisory board for many pharmaceutical companies, including AbbVie.

Delusions of parasitosis is linked to female gender, older age, polypharmacy with more than five drugs, and certain types of drugs (attention-deficit/hyperactivity disorder drugs, selective serotonin reuptake inhibitors, gabapentin, and opioids), reported researchers in a small retrospective case-control study.

Delusions of parasitosis (DOP) affects mostly middle-aged women and has associations with renal failure and some medications, wrote corresponding author Colleen Reisz, MD, a dermatologist with the department of internal medicine at the University of Missouri–Kansas City School of Medicine, and her coauthors. The study was published online December 15, 2023, in the Journal of the American Academy of Dermatology.

“We hypothesize that vulnerability to DOP emerges when multiple factors combine, such as age, sex, medications, and changes in [drug] clearance capacity,” Dr. Reisz and her coauthors wrote. “Changes in health care, such as the dramatic increase in stimulant prescriptions and alternatives to opioids in pain management, may be contributing to off target drug effects on the brain.”

[embed:render:related:node:235540]

To test their hypothesis, the researchers conducted a case-control study of biometric and pharmaceutical data from 34 patients with DOP which they compared to an age-matched control group of 53 women presenting with a dermatitis above the clavicle from a general dermatology practice between 2012 and 2020. They de-identified the data and performed statistical analysis on variables that included biometric data and intake of pharmaceuticals and nutraceuticals. Polypharmacy was defined as five or more drugs.

Of the 34 patients with DOP, 27 were women with a mean age of 58 years and 7 were men with a mean age of 60 years. Dr. Reisz and her colleagues observed statistical significance between cases and controls in terms of polypharmacy (P = .011), attention-deficit/hyperactivity disorder medications (P < .001), selective serotonin reuptake inhibitors (P = .005), opioids (P = .003), and gabapentin (P = .003).

In other findings, half of DOP cases presented with samples of perceived parasitic material, and four associated the perceived infestation with a single emotion-laden event. This prompted the researchers “to consider that DOP may share mechanisms with fear conditioning and extinction,” they wrote. “Fear conditioning refers to the process of memory acquisition and extinction. This process is essential for survival and has been studied in posttraumatic stress disorder.”

They acknowledged certain limitations of the study, including its retrospective single-center design and the lack of control for factors such as socioeconomic background and level of education.

“Patients with DOP should undergo detailed drug histories and examination of clearance profiles, especially renal function,” the researchers concluded.

Evan A. Rieder, MD, a New York City–based dermatologist and psychiatrist who was asked to comment on the study, said that delusional infestation is one of the most difficult medical conditions to treat and study.

“Though the numbers of cases in this research letter are small, they are instructive in demonstrating a high burden of polypharmacy including psychostimulants, opioids, and SSRIs in such patients,” he told this news organization. “Dermatologists should be performing detailed drug histories, obtaining comprehensive lab work, and considering the effects of medications — both illicit and prescribed — on clinical presentations. While in many cases, delusional patients refuse to consent to psychopharmacologic medications (or treatment in general), the elimination or decrease in dose of certain problematic medications may be helpful in and of themselves.”

The researchers reported having no financial disclosures. Dr. Rieder disclosed that he is a consultant for AbbVie, L’Oréal, Pierre Fabre, Procter & Gamble, and Unilever.

The FDA has approved a topical gel containing birch triterpenes for the treatment of partial thickness wounds in patients 6 months and older with junctional epidermolysis bullosa (JEB) and dystrophic epidermolysis bullosa (DEB).

The gel is marketed under the name Filsuvez. It is the first approved treatment for wounds associated with JEB and the second for patients with DEB, following the approval of Vyjuvek (Krystal Biotech), a topical gene therapy gel, in May 2023.

First developed by Amryt Pharma and intended for home use, Filsuvez is now marketed by Chiesi Global Rare Diseases, which acquired Amryt in January 2023. The gel is applied topically to the wound at each dressing change.

[embed:render:related:node:264410]

The approval of Filsuvez is based on results from the Efficacy and Safety Study of Oleogel-S10 in Epidermolysis Bullosa (EASE), a randomized, placebo-controlled study of 223 people, the largest-ever phase 3 clinical trial for the treatment of EB, according to the Chiesi news release. The gel was well tolerated and met the primary endpoint with statistical significance, with 41.3% of patients achieving first complete target wound closure within 45 days (compared with 28.9% on placebo).

“I am so excited to say that this is another hurdle cleared and milestone achieved for the EB Community,” Brett Kopelan, executive director at debra of America said in a blog post. “We are now on the road to being able to treat EB more effectively, and to make the worst disease you’ve never heard of chronic, but livable, by making use of multiple therapeutic options in conjunction with each other.”

First developed by Amryt Pharma and intended for home use, Filsuvez is now marketed by Chiesi Global Rare Diseases, which acquired Amryt in January 2023. The gel is applied topically to the wound at each dressing change.

The approval of Filsuvez is based on results from the Efficacy and Safety Study of Oleogel-S10 in Epidermolysis Bullosa (EASE), a randomized, placebo-controlled study of 223 people, the largest-ever phase 3 clinical trial for the treatment of EB, according to the Chiesi news release. The gel was well tolerated and met the primary endpoint with statistical significance, with 41.3% of patients achieving first complete target wound closure within 45 days (compared with 28.9% on placebo).

“I am so excited to say that this is another hurdle cleared and milestone achieved for the EB Community,” Brett Kopelan, executive director at debra of America said in a blog post. “We are now on the road to being able to treat EB more effectively, and to make the worst disease you’ve never heard of chronic, but livable, by making use of multiple therapeutic options in conjunction with each other.”

Lebrikizumab, an investigational interleukin-13 inhibitor, showed significant efficacy compared with placebo across racial and ethnic subgroups in patients with moderate-to-severe atopic dermatitis.

The finding comes from an analysis of the 16-week induction periods of the phase 3 ADvocate1 and ADvocate2 trials, which Raj Chovatiya, MD, PhD, presented during a late-breaking abstract session at the Revolutionizing Atopic Dermatitis (RAD) Virtual Conference. The efficacy of lebrikizumab monotherapy to treat moderate-to-severe AD has been established in phase 3 studies, “but disease characteristic and efficacy outcomes may vary among racial and ethnic subgroups,” said Dr. Chovatiya, assistant professor in the department of dermatology at Northwestern University, Chicago. “The goal of the current study is to report the week 16 efficacy of lebrikizumab-treated patients in racial and ethnic subgroups from ADvocate1 and ADvocate2.”

Key eligibility criteria for both trials included adults or adolescents with a diagnosis of AD as defined by the American Academy of Dermatology Consensus Criteria, for at least 1 year prior to screening. They had moderate-to-severe AD, were candidates for systemic therapy, and were dupilumab- and tralokinumab-naive. Outcomes of interest were the Investigator’s Global Assessment 0 or 1, with at least a 2-point improvement; and the proportions of patients who achieved Eczema Area and Severity Index (EASI75) and EASI90 responses, and an improvement of 4 points or more on the Pruritus Numeric Rating Scale (NRS).

For statistical analysis, the researchers pooled data from Advocate1 and Advocate2 and applied imputation methodology to the 16-week induction period. Subsequent data from patients who received topical or systemic rescue medication or discontinued treatment due to lack of efficacy were imputed as nonresponders. Subsequent data from patients who discontinued treatment for other reasons were set to missing, and the researchers handled missing data with multiple imputation. They used logistic regression to test the interaction between the treatment and subgroup and the Cochran-Mantel-Haenszel method to evaluate the treatment effect within each subgroup after adjusting for stratification factors.

Dr. Chovatiya reported findings from the 851 study participants in the combined studies. Of these, 542 were White, 192 were Asian, 84 were Black, and 33 were from other racial subgroups. By ethnic subgroup, 748 were not Hispanic or Latino, 91 were Hispanic or Latino, and ethnicity was unknown or not reported for 12 subjects. At baseline, the mean body mass index was slightly higher among Blacks (30.4 kg/m²) and Hispanics (29.4 kg/m²) compared with other racial and ethnic groups, “which reflects general epidemiologic data among these groups in the United States,” Dr. Chovatiya said. “You can also see a difference in the balance of IGA scores — they were a little bit more severe in the Black or African American and Hispanic groups as well.” The researchers also observed differences in the baseline EASI score across some of these groups, particularly in the Asian individuals, who had higher EASI scores. Prior use of systemic therapy was lower in the Black and “other” subgroups, compared with other racial subgroups.

At week 16, key efficacy endpoints were generally similar between the different racial subgroups. Specifically, 25.1% of Asians in the lebrikizumab treatment group achieved an IGA of 0/1, compared with 4.1% of those in the placebo group (P < .001), while 33.2% of Blacks in the lebrikizumab treatment group achieved an IGA of 0/1, compared with 13.2% of those in the placebo group (no P value was established because this subgroup represented less than 10% of the entire study population). In addition, 43.3% of Whites in the lebrikizumab treatment group achieved an IGA of 0/1, compared with 14.1% of those in the placebo group (P < .001).

[embed:render:related:node:261829]

In other findings, 45.5% of Asians in the lebrikizumab treatment group achieved an EASI75, compared with 8.5% of those in the placebo group (P < .001), while 51.7% of Blacks in the lebrikizumab treatment group achieved an EASI75, compared with 18.8% of those in the placebo group. Among whites in the lebrikizumab treatment group, 59.7% of achieved an EASI75, compared with 20.4% of those in the placebo group (P < .001).

Dr. Chovatiya said that 26.5% of Asians in the lebrikizumab treatment group achieved an EASI90, compared with 4.3% of those in the placebo group (P < .001), while 26.9% of Blacks in the lebrikizumab treatment group achieved an EASI90, compared with 13.2% of those in the placebo group. In addition, 38.3% of Whites in the lebrikizumab treatment group achieved an EASI90, compared with 10.9% of those in the placebo group (P < .001).

Finally, 36.4% of Asians in the lebrikizumab treatment group achieved a 4-point or greater improvement on the NRS, compared with 5.7% of those in the placebo group (P <. 001), while 41.7% of Blacks in the lebrikizumab treatment group achieved a 4-point or greater improvement on the NRS, compared with 17.4% of those in the placebo group. In addition, 45.9% of Whites in the lebrikizumab treatment group achieved a 4-point or greater improvement on the NRS, compared with 14.8% of those in the placebo group (P < .001). Statistical analyses of efficacy endpoints conducted by ethnic group yielded similar results.

Dr. Chovatiya acknowledged certain limitations of the study, including the fact that differences in baseline demographics and disease characteristics limit direct comparison across racial and ethnic subgroups. “Due to the relatively small sample size of some racial and ethnic subgroups and the post hoc nature of this analysis, additional studies are needed to verify these results,” he concluded. But for now, he said, the data available indicate that “lebrikizumab is effective across racial and ethnic subgroups for the treatment of moderate-to-severe AD after 16 weeks of monotherapy treatment.”

The study was funded by Dermira, a wholly owned subsidiary of Eli Lilly and Company. Dr. Chovatiya disclosed that he is speaker for and/or a consult and advisory board member to many pharmaceutical companies, including Eli Lilly.

A significant number of patients with moderate-to-severe atopic dermatitis (AD) failed to achieve adequate disease control with systemic therapies over 12 months in a study of patient registry data, indicating a substantial degree of “therapeutic inertia,” the study’s lead author, Jonathan I. Silverberg, MD, PhD, MPH, reported.

The findings come from an analysis of real-world outcomes from the TARGET-DERM AD registry, which Dr. Silverberg, professor and director of clinical research and contact dermatitis in the department of dermatology at George Washington University, Washington, presented during a late-breaking abstract session at the Revolutionizing Atopic Dermatitis (RAD) Virtual Conference. He characterized the findings as “patients just getting stuck with a therapy and not advancing when they need to.”

TARGET-DERM AD is a longitudinal observational study of people with AD at 39 academic centers in the United States and Canada. Dr. Silverberg and his coinvestigators evaluated the proportion of patients who were experiencing an inadequate response after receiving systemic therapy and continuing on the same treatment for 3-12 months. “These are patients who are receiving their first or advanced systemic therapy, and the question is, how long did they stay on it, even if they’re not doing so well?” Dr. Silverberg said.

Silverberg_Jonathan_Washingt_web.jpg

The researchers identified and compared the proportions of patients not achieving moderate or optimal clinician-reported outcome targets on patients with AD treated with their first systemic therapy. Advanced systemic therapy (AST) included abrocitinib, dupilumab, tralokinumab, or upadacitinib, while conventional systemic therapy (CST) included methotrexate, cyclosporine, mycophenolate mofetil, azathioprine, and systemic corticosteroids.

Patients in TARGET-DERM AD were treated and maintained on their first systemic therapy (either advanced or conventional) for up to 12 months. They had a validated Investigator’s Global Assessment of AD (vIGA-AD) score of 3 or 4 less than 45 days prior to initiation of systemic therapy or up to 14 days afterward. They also had at least one vIGA-AD assessment 3-12 months after initiating treatment. Outcome measures included IGA (defined as a score of 2 or less, with an optional target of 0 or 1), BSA (defined as a 50% BSA improvement, with an optimal target BSA of 2% or less), and the Worst-Itch Numeric Rating Scale (defined as at least a 4-point reduction, with an optimal target of 1 or less).

The analysis included 445 patients with a mean age of 31 years at enrollment. More than half (62%) were female and 45% were non-Hispanic Whites. Most patients (92%) were on an AST, mainly dupilumab, with smaller proportions treated with either tralokinumab, upadacitinib, or abrocitinib. Fewer than 10% of patients in the registry were being treated with CSTs.

[embed:render:related:node:266721]

At 6 months, 37% and approximately 67% of the AST-treated patients had inadequate responses in terms of skin clearance and itch outcomes, respectively. At 12 months, these figures were about 30% and 66%, respectively. CST-treated patients showed a similar trend. For patients starting an AST on or after Sept. 21, 2021, when three additional AST options were available (tralokinumab, upadacitinib, and abrocitinib), the proportion of patients demonstrating an adequate response over 12 months was generally similar to the overall cohort of those on ASTs.

“These findings suggest a need for alternative therapies and management strategies in AD treatment,” concluded Dr. Silverberg, who chaired the RAD symposium.

SAN DIEGO — Clinically significant interstitial lung disease (ILD) is believed to occur in 5%-10% of patients with rheumatoid arthritis (RA), but robust data are lacking on how to best predict which patients face the highest risk for RA-associated ILD. However, the results of several studies presented at the American College of Rheumatology annual meeting indicate that researchers are making strides in this field of rheumatologic care.

Adding Genetic Factors Improves ILD Risk Prediction

In the realm of risk stratification, Austin M. Wheeler, MD, a rheumatology fellow at the University of Nebraska Medical Center, Omaha, discussed the development and validation of a combined clinical and genetic risk score for ILD. “There is clear and well documented phenotypic and genetic overlap of ILD with idiopathic pulmonary fibrosis (IPF),” Dr. Wheeler said. “A number of clinical risk factors have been described for RA-ILD, including older age, male sex, smoking history, higher disease activity, and seropositivity. There are also well-documented genetic risk factors for RA-ILD. The MUC5B genetic variant is the strongest risk factor for IPF, and it’s been described in RA-ILD as well.”

A recently published study indicated that a genetic risk score without the MUC5B variant improved predictive ability for IPF and interstitial lung abnormalities better than using the MUC5B variant alone, “but no prior attempts have been made at developing a composite genetic risk score in RA-ILD” using both genetic and clinical risk factors, he said.

For the current study, Dr. Wheeler and colleagues drew from 2,386 participants in the Veterans Affairs Rheumatoid Arthritis (VARA) Registry, a multicenter, prospective cohort of US veterans with rheumatologist-diagnosed RA and who fulfilled the 1987 ACR classification criteria. The researchers validated ILD through a systematic review of medical records, including clinical diagnosis of ILD plus either imaging or lung biopsy findings, and collected whole genome data that included 12 single nucleotide polymorphisms (SNPs) previously identified to be associated with risk for RA-ILD. They then used a meta-analytic approach to create pooled associations for each of those respective SNPs using data from the VARA registry participants as well as participants from the past study where the SNPs were first identified. “Those pooled associations were what we used for our effects size within the genetic risk score,” which ended up using five of the SNPs, Dr. Wheeler explained. Next, he and his colleagues combined the genetic risk score with clinical risk factors including age, sex, smoking history, disease activity, and rheumatoid factor (RF) positivity to create their combined risk score.

The mean age of the cohort was 70 years, 89% were male, 78% had a smoking history, and 78% were anti–cyclic citrullinated peptide (CCP) antibody positive. Of the 2,386 participants, 224 (9.4%) had RA-ILD. The full composite risk score had the highest area under the receiver operating curve (AUC) of 0.67, compared with an AUC of 0.623 using the clinical factors alone, 0.651 using the clinical factors plus only the MUC5B variant, and 0.654 using the composite score minus only the MUC5B variant. These AUCs show that “the combined risk score performs better than clinical factors even without the inclusion of the MUC5B variant in the score, which is notable because it supports the importance of further investigation into polygenic risk scores in RA-ILD as there is clearly more at play in a patient’s overall genetic risk,” Dr. Wheeler said.

As an example of the composite score’s ability to discriminate between people with and without RA-ILD, a cutpoint of 0.05 gave a sensitivity of 90.2% and would have eliminated about 25% of the cohort from unnecessary high-resolution CT scans and pulmonary function tests, he said.

“This study demonstrates the potential utility of genetic risk scores in RA-ILD identification and supports further investigation into individual risk stratification and screening,” he concluded. “This isn’t ready for clinical applicability by any means, but I think it serves as a proof of concept of the idea of a genetic risk score in RA-ILD.”

Biomarker Score Investigated

In a separate abstract, Brent Luedders, MD, assistant professor of rheumatology and immunology at the University of Nebraska Medical Center, and colleagues set out to determine if a previously derived biomarker score is associated with prevalent and incident ILD in the same VARA Registry cohort. An abstract presented at the ACR 2022 annual meeting found that a panel derived from IPF peripheral biomarkers was significantly associated with RA-ILD, including matrix metalloproteinase (MMP)-2, -7, and -9, eotaxin, macrophage-derived chemokine (MDC), monocyte chemoattractant protein-1 (MCP-1), fms-like tyrosine kinase 3 ligand (Flt3L) and interleukin-8 (IL-8). For the current analysis, Dr. Luedders and colleagues measured the concentrations of seven biomarkers (MMP-7, MMP-9, eotaxin, MDC, MCP-1, Flt3L, IL-8) from serum/plasma samples collected from VARA’s participants at enrollment to develop a score based on the concentrations of each biomarker.

Baseline characteristics were similar between the groups, although those with prevalent RA-ILD were slightly older than those without ILD, and those who developed incident ILD during follow-up had slightly higher RA disease activity at the time of enrollment. When the researchers examined the association of the biomarker score with prevalent RA-ILD as a continuous measure, they found an adjusted OR of 1.08 for prevalent RA-ILD for each 1-point increase in the biomarker score. “When this was divided into quartiles, we found that the highest quartile of the biomarker score was associated with an adjusted odds ratio of 2.31 for prevalent RA-ILD,” Dr. Luedders said. “We saw a significant P for trend of < .001, suggesting a dose-response relationship, in which higher scores had higher risk.” Similar associations were observed for incident RA-ILD, in which participants with the highest quartile had an adjusted hazard ratio of 2.26 for incident RA-ILD.

The AUC of 0.653 that was obtained with clinical factors did not significantly improve with inclusion of the biomarker score, rising to only 0.669. “In receiver operating characteristic analysis, the addition of the biomarker score to clinical variables (age, sex, race, smoking status, anti-CCP positivity, and RA disease activity by DAS28) did not lead to a significant increase in the area under the curve. Therefore, further work is needed to identify combinations of clinical, biomarker, and other factors to accurately predict which people with RA will develop ILD,” he said.

Dr. Luedders acknowledged certain limitations of the results, including the fact that MMP-2 was not measured in this cohort and thus not included in the score. “This was an observational study with usual care; therefore, the absence of systemic evaluation for ILD may miss early or mild RA-ILD cases,” he added. “Similarly, a male predominance may limit the generalizability, and we have limited information on the RA-ILD pattern.” He concluded that the study results “support the shared pathogenesis of IPF and RA-ILD. However, we found that this score has limited discriminative performance, compared to clinical risk factors alone.”
 

Drilling Down on ILD Subtypes

In a poster abstract presentation at the meeting, Gregory Campbell McDermott, MD, MPH, a rheumatologist at Brigham and Women’s Hospital, Boston, highlighted results from a study that investigated differences in demographic, serologic, and lifestyle factors for RA-ILD and the major subtypes of RA-ILD: usual interstitial pneumonia (UIP) and nonspecific interstitial pneumonia (NSIP). “Historically, RA-ILD has been studied as a single entity, even though we increasingly recognized that there are lots of different subtypes that fall under the umbrella of RA-ILD,” Dr. McDermott said in an interview. “We are also learning that the different subtypes probably have both prognostic and potentially therapeutic implications. For example, the UIP subtype, which is the most fibrotic subtype, has the worst prognosis but also may be a potential target for antifibrotic therapies. We’ve been trying to see if we can identify factors that are associated with specific subtypes, in particular the UIP subtype which has the worst prognosis.”

He and his colleagues examined 208 patients with RA-ILD with a mean age of 51 years and 547 patients with RA but no ILD with a mean age of 49 years from two RA cohorts comprising 3,328 patients: the Mass General Brigham Biobank RA Cohort and the Brigham RA Sequential Study (BRASS). Of the 208 RA-ILD cases, nearly half (48%) were RA-UIP, 18% were RA-NSIP, 8% were organizing pneumonia, 3% were respiratory bronchiolitis-ILD, and 23% were other/indeterminate. After conducting multivariable adjusted analyses, the researchers found that RA-ILD was associated with male sex (OR, 1.58; 95% CI, 1.09-2.23), seropositivity for RF and/or anti-CCP (OR, 2.22; 95% CI, 1.51-3.24) and being an ever smoker (OR, 1.70; 95% CI, 1.13-2.54). Having all three of these risk factors was strongly associated with RA-ILD (OR, 6.04; 95% CI, 2.92-12.47) and with RA-UIP in particular (OR, 7.1). “We found that a lot of the traditional RA-ILD risk factors like male sex, history of smoking, and seropositive status were most strongly associated with a UIP pattern,” Dr. McDermott said. “We think this is a first step in trying to understand how these different ILD subtypes may have different risk factors, pathogenesis, and potentially different treatments, prevention, and screening strategies.”

While clinicians wait for guidelines on systemic autoimmune rheumatic disease-associated ILD that are expected to be published by the ACR in 2024, he added that “we probably shouldn’t screen every single person with RA for ILD, but we need to identify people who have symptoms or findings on clinical exam. This study wasn’t designed to look specifically at who is at high risk, but I think we are moving toward that question: Who is high risk, and who’s asymptomatic [but] may need more screening?”

He pointed out limitations of the study, including its retrospective design and the fact that imaging was done for clinical purposes, “so it’s probably a higher risk group to begin with than the whole RA population,” he said. “We also didn’t have data on RA disease activity or erosions, some of these other measures that we think are important for understanding the full RA disease phenotype in these patients.”

SAN DIEGO — Clinically significant interstitial lung disease (ILD) is believed to occur in 5%-10% of patients with rheumatoid arthritis (RA), but robust data are lacking on how to best predict which patients face the highest risk for RA-associated ILD. However, the results of several studies presented at the American College of Rheumatology annual meeting indicate that researchers are making strides in this field of rheumatologic care.

Adding Genetic Factors Improves ILD Risk Prediction

In the realm of risk stratification, Austin M. Wheeler, MD, a rheumatology fellow at the University of Nebraska Medical Center, Omaha, discussed the development and validation of a combined clinical and genetic risk score for ILD. “There is clear and well documented phenotypic and genetic overlap of ILD with idiopathic pulmonary fibrosis (IPF),” Dr. Wheeler said. “A number of clinical risk factors have been described for RA-ILD, including older age, male sex, smoking history, higher disease activity, and seropositivity. There are also well-documented genetic risk factors for RA-ILD. The MUC5B genetic variant is the strongest risk factor for IPF, and it’s been described in RA-ILD as well.”

Tape stripping, which allows sampling of the epidermis to the midgranular layer, is a valid, minimally invasive way to identify cutaneous biomarkers in patients with hidradenitis suppurative (HS), results from a novel study showed.

“Tape strips can provide important clues to when and which drugs to use in HS in patients with both early and late disease, which can change clinical practice,” corresponding study author Emma Guttman-Yassky, MD, PhD, professor and chair of dermatology at the Icahn School of Medicine at Mount Sinai in New York City, said in an interview. “It is noninvasive and nonscarring,” she added.

Tape stripping has been validated in atopic dermatitis, psoriasis, and other dermatologic conditions in recent years. For the current study, which was published online in the Journal of the American Academy of Dermatology, and is believed to be the first of its kind, Dr. Guttman-Yassky and colleagues performed RNA sequencing from large D-Squame tape strips collected from lesional and nonlesional skin of 22 patients with HS and from 21 age- and sex-matched healthy controls. They correlated the expression of skin biomarkers between tape strips and a previously published gene-signature of HS biopsies. The mean age of patients with HS was 43 years, while the mean age of healthy controls was 35. The average International Hidradenitis Suppurativa Severity Score System (IHS4) score of the HS cohort was 36.

Consistent with published studies, the researchers found that tape strips identified an overall higher inflammatory burden in HS. Specifically, they observed an upregulation of known cytokines within the following pathways: Th1 (such as IFNG, CXCL9/10/11, and CCR5); Th17 (such as interleukin [IL]-17A/F, IL12B, IL23A, CAMP, and CCL20); Th2 (such as IL4R, IL13/IL31/IL10, CCR4, CCL7/CCL13/CCL24, TNFSF4/OX40L, and TNFRSF4/OX40); and Th22 (such as IL22 and IL32).

The researchers also found that the expression of Th17 and tumor necrosis factor (TNF)–alpha pathways were highly correlated between tape strips and biopsies and that HS clinical severity was significantly associated with expression of biomarkers, such as TNF-alpha, IL17A/F, OX40, JAK1-3, and IL4R in HS lesional and/or nonlesional skin.

“It was quite unexpected that we are able to identify, using a minimally invasive approach that samples only the upper layers of the epidermis, products and processes that are considered to be deeper-situated, such as IL-17, and other immune markers,” Dr. Guttman-Yassky said in the interview. “We were also surprised to see how well the tape-stripped–derived skin molecular profile correlated with that of biopsies, as well as how well it correlated with the clinical disease severity of HS.”

Also surprising, she added, was that the biomarkers in nonlesional tape-stripped skin, such as IL-17 and TNF alpha, “show high correlations with disease severity and provide clues to early disease.”

If using tape strips in HS is validated in larger cohort studies, the potential cost implications of using this approach in practice remain unclear, Dr. Guttman-Yassky said. “It is currently not cheap, but we are hoping that one day, we can provide a means to diagnose the disease and treat it early, and appropriately, utilizing this approach,” she commented. “We are excited about the applicability of this study to the early treatment and longitudinal follow up of HS with drugs that are targeting specific immune molecules and pathways,” she said, adding that it will also be useful for helping determine which drug should be used for which patient.

She and her co-authors acknowledged certain limitations of the study, including its small sample size and the fact that tape stripping is limited to the epidermis.

Asked to comment on the study, Jennifer L. Hsiao, MD, a dermatologist who directs the HS clinic at the University of Southern California, Los Angeles, said the findings “have important potential implications for our ability to one day personalize treatments for a patient with early HS in a minimally invasive way.”

As the study authors point out, she added, “tape strips only allow sampling of the epidermis, which is limiting in a disease like HS where much of the disruption is in the dermis with deep nodules and dermal tunnels. However, our overall goal should be to catch patients in the early stages of their disease before the occurrence of irreversible tissue damage such as dermal tunnels. Thus, the ongoing campaign for early diagnosis and early intervention by various stakeholders in the field of HS can help mitigate the impact of this inherent limitation of tape strips. It will be exciting to see larger studies that investigate tape strip results in relation to clinical phenotypes, disease progression, and therapeutic responses.”

The study was funded by an International Dermatology Outcome Measures Hidradenitis Suppurativa Grant. Dr. Guttman-Yassky disclosed that she has been a consultant to, an adviser for, and has received research grants from many pharmaceutical companies. Of the remaining authors, 2 also had multiple disclosures and 11 had no disclosures. Dr. Hsiao disclosed that she is a member of the board of directors for the Hidradenitis Suppurativa Foundation. She has also served as a consultant for AbbVie, Aclaris, Boehringer Ingelheim, Incyte, Novartis, and UCB; as a speaker for AbbVie; and as an investigator for Amgen, Boehringer Ingelheim, and Incyte.

Tape stripping, which allows sampling of the epidermis to the midgranular layer, is a valid, minimally invasive way to identify cutaneous biomarkers in patients with hidradenitis suppurative (HS), results from a novel study showed.

“Tape strips can provide important clues to when and which drugs to use in HS in patients with both early and late disease, which can change clinical practice,” corresponding study author Emma Guttman-Yassky, MD, PhD, professor and chair of dermatology at the Icahn School of Medicine at Mount Sinai in New York City, said in an interview. “It is noninvasive and nonscarring,” she added.

Tape stripping has been validated in atopic dermatitis, psoriasis, and other dermatologic conditions in recent years. For the current study, which was published online in the Journal of the American Academy of Dermatology, and is believed to be the first of its kind, Dr. Guttman-Yassky and colleagues performed RNA sequencing from large D-Squame tape strips collected from lesional and nonlesional skin of 22 patients with HS and from 21 age- and sex-matched healthy controls. They correlated the expression of skin biomarkers between tape strips and a previously published gene-signature of HS biopsies. The mean age of patients with HS was 43 years, while the mean age of healthy controls was 35. The average International Hidradenitis Suppurativa Severity Score System (IHS4) score of the HS cohort was 36.

Consistent with published studies, the researchers found that tape strips identified an overall higher inflammatory burden in HS. Specifically, they observed an upregulation of known cytokines within the following pathways: Th1 (such as IFNG, CXCL9/10/11, and CCR5); Th17 (such as interleukin [IL]-17A/F, IL12B, IL23A, CAMP, and CCL20); Th2 (such as IL4R, IL13/IL31/IL10, CCR4, CCL7/CCL13/CCL24, TNFSF4/OX40L, and TNFRSF4/OX40); and Th22 (such as IL22 and IL32).

The researchers also found that the expression of Th17 and tumor necrosis factor (TNF)–alpha pathways were highly correlated between tape strips and biopsies and that HS clinical severity was significantly associated with expression of biomarkers, such as TNF-alpha, IL17A/F, OX40, JAK1-3, and IL4R in HS lesional and/or nonlesional skin.

In a letter dated Nov. 30, 2023, the Food and Drug Administration informed isotretinoin manufacturers that they have 6 months to make five changes to existing iPLEDGE Risk Evaluation and Mitigation Strategy (REMS) requirements for the acne drug isotretinoin.

The development follows a March 2023 joint meeting of the FDA’s Drug Safety and Risk Management Advisory Committee and the Dermatologic and Ophthalmic Drugs Advisory Committee about iPLEDGE REMS requirements, which included feedback from patients and dermatologists and recommendations for changes to the REMS program, aimed at minimizing the burden of the program on patients, pharmacies, and prescribers while continuing to maintain safe use of the highly teratogenic drug for patients.

The five changes include the following:

• Remove the requirement that pregnancy tests must be performed in a specially certified (i.e., Clinical Laboratory Improvement Amendments [CLIA]) laboratory. In the opinion of John S. Barbieri, MD, MBA, director of the Advanced Acne Therapeutics Clinic at Brigham and Women’s Hospital, Boston, this change “may make it easier to perform pregnancy tests in a clinic setting without needing to send the patient to a separate lab,” he said in an interview.
• Allow prescribers the option of using home pregnancy testing for their patients during and after isotretinoin treatment. Prescribers who rely on the patient to perform a home pregnancy test need to take steps to minimize patients falsifying the results of these tests. According to Dr. Barbieri, this means that two pregnancy tests prior to starting isotretinoin must be done in a lab or office setting. “However, all the pregnancy tests on therapy can be either in a medical setting or using a home pregnancy test,” he told this news organization. “This option facilitates the use of telemedicine so that patients would not need to come in; they can just share a pregnancy test with their name and date with their dermatologist.”
• Remove the waiting period requirement — also known as the “19-day lockout” — for patients if they do not obtain isotretinoin within the first 7-day prescription window. According to Dr. Barbieri, this change helps to ensure that patients can begin isotretinoin in a timely manner. “Insurance and pharmacy delays that are no fault of the patient can commonly cause missed initial window periods,” he said. “Allowing for immediate repeat of a pregnancy test to start a new window period, rather than requiring the patient to wait 19 more days, can ensure patient safety and pregnancy prevention without negatively impacting access.”
• Revise the pregnancy registry requirement to remove the objective to document the pregnancy and fetal outcomes for each pregnancy.
• Revise the requirement for prescribers to document patient counseling in patients who cannot become pregnant from monthly to only at enrollment. Dr. Barbieri characterized this change as “major” and said that it could eliminate the need for monthly visits for persons of non–childbearing potential. “This could substantially reduce logistical burdens for patients and reduce wait times to see a dermatologist,” he said.

Future changes to iPLEDGE that Dr. Barbieri would like to see include allowing for home pregnancy tests prior to starting therapy — particularly the test after the 30-day window period. “In addition, it would be good to be able to reduce the 30-day waiting period prior to therapy to something shorter,” such as 14 days, which would still “reliably exclude pregnancy, particularly for those on stable long-acting reversible contraception,” he said. There are also opportunities to improve the iPLEDGE website functionality and to ensure that the website is accessible to patients with limited English proficiency, he added.

He also recommended greater transparency by the Isotretinoin Products Manufacturers Group and inclusion of input from diverse stakeholders such as dermatologists, patients, and pharmacists.
