Key clinical point: In patients with episodic migraine (EM) or chronic migraine (CM), erenumab treatment interruption was associated with increased monthly migraine days (MMD) and worsening of migraine disability; these effects ameliorated on treatment restart.

Major finding: After erenumab treatment interruption for 3 months, the number of monthly migraine days (MMD) increased from 6.1 to 10.9 days for patients with EM and from 11.4 to 16.8 days for patients with CM; the modified Migraine Disability Assessment scores (mMIDAS) also worsened during this period. Both MMD and mMIDAS scores improved upon restarting treatment.

Study details: This interim analysis of the 24-month, multicentric, non-interventional observational study included 172 patients with CM or EM who received erenumab and underwent treatment interruptions on average 11.2 months after initiation, with interruptions lasting for a mean duration of 4 months.

Key clinical point: Atogepant was effective in reducing monthly migraine days (MMD), monthly headache days (MHD), and acute medication use days in patients with chronic migraine (CM), irrespective of acute medication overuse.

Major findings: Patients with acute medication overuse receiving 30 mg or 60 mg atogepant vs placebo had a significantly greater reduction in MMD (least squares mean difference [LSMD] −2.7 and −1.9, respectively), MHD (LSMD −2.8 and −2.1, respectively), and monthly acute medication use days (LSMD −2.8 and −2.6, respectively). Similar reductions were observed in patients without acute medication overuse.

Study details: This subgroup analysis of the PROGRESS trial included 755 patients with CM with or without acute medication overuse who were randomly assigned to receive atogepant (30 mg or 60 mg) or placebo.

In this real-life study, Patruno and colleagues found that dupilumab worked well but more slowly in patients with a higher body mass index (BMI). On the basis of these findings, if patients are not in a hurry, the standard dose of dupilumab should eventually work, regardless of BMI. If patients are in a hurry to see improvement, perhaps dose escalation could be considered for patients with a high BMI, or perhaps topical triamcinolone could be used to speed time-to–initial resolution in the high-BMI population.

In the very well-done study by Silverberg and colleagues, tapinarof was effective, well tolerated, and generally safe for atopic dermatitis in adults and children. Great! Topical tapinarof should soon be another good option for our patients with atopic dermatitis. How valuable will it be? We already have topical corticosteroids that are very effective for atopic dermatitis, and we have multiple other nonsteroidal topical agents, including topical calcineurin inhibitors and topical ruxolitinib. 

Perhaps the biggest limitation of all these treatments is poor adherence to topical treatment. I'm not sure how effective even highly effective nonsteroidal topicals will be for patients who did not respond to topical steroids when the primary reason for topical steroid failure is poor treatment adherence. I'd love to see the development of a once-a-week or once-a-month topical therapy that would address the poor-adherence hurdle.

Abrocitinib is an effective treatment for improving atopic dermatitis. Although atopic dermatitis is a chronic condition requiring long-term management, we'd like to minimize exposure to the drug to avoid side effects. Thyssen and colleagues described the effectiveness of two maintenance treatment regimens: continuing 200 mg/d or reducing the dose to 100 mg/d. Both regimens prevented flares more than did placebo. This study also provided information on safety of the maintenance regimens. Rates of herpetic infections were low across all the groups, but unlike the two treatment groups, there were no cases of herpes simplex infection in the patients in the placebo arm.

Key clinical point: Patients with atopic dermatitis (AD) who had many or severe flares were more likely to report higher disease severity and impairment in quality of life than those who had no or few flares.

Major finding: Patients with 1-5, 6-10, or >10 flares had higher median Patient-Oriented SCORing for Atopic Dermatitis (29.7, 36.3, and 42.9, respectively) and Dermatology Life Quality Index (3, 4, and 7, respectively) scores than those without flares.

Study details: This Danish population-based study included 1557 patients with AD who had 0 (n = 57), 1-5 (n = 698), 6-10 (n = 324), or >10 (n = 478) flares during the past 12 months.

Disclosures: The study was funded by Almirall S.A., Barcelona, Spain. Three authors declared being employees of Almirall, whereas the remaining authors reported having various ties with Almirall and other sources.
