LID - 10.1111/pde.15575 [doi] AB - OBJECTIVE: Controlling molluscum contagiosum (MC) infections is critical in atopic dermatitis (AD) management. This post hoc analysis assessed the efficacy and safety of berdazimer gel, 10.3% (topical, antiviral, nitric oxide-releasing medication) versus vehicle in MC patients with or without AD. METHODS: Three Phase 3, multicenter, randomized, double-blind, vehicle-controlled, parallel-group trials (B-SIMPLE[berdazimer sodium in molluscum patients with lesions]1, -2, -4) enrolled patients 6 months and older with 3-70 mollusca. Berdazimer or vehicle was applied once daily to all MC lesions for 12 weeks. Data from three Phase 3 studies were integrated for subgroup efficacy and safety assessments using several weighted meta-analysis approaches. Patients with concurrent AD or a history of AD/eczema were categorized as AD+ subgroup (AD- when absent). Primary efficacy endpoint: complete lesion clearance at Week 12. Safety endpoints included adverse events (AEs) through Week 24 and local skin reactions through Week 12. RESULTS: Of 1598 enrolled patients, 209 (13.1%) were AD+. Baseline mean lesion counts were greater in AD+ (26.4) than AD- (19.3). Complete clearance rates were higher at Week 12 for berdazimer compared with vehicle in AD+ (n = 209; 35.0% vs. 27.4%; odds ratio [OR], 1.3; 95% CI, 0.7-2.5) and AD- (n = 1389; 29.1% vs. 18.9%; OR 1.8; 95% CI 1.4-2.4) subgroups. AEs in AD+ were application-site pain (21.6% with berdazimer vs. 11.9% with vehicle), dermatitis (12.8% vs. 2.4%), and erythema (9.6% vs. 7.1%). CONCLUSIONS: Berdazimer gel showed favorable efficacy regardless of AD status. Berdazimer-induced erythema may be indistinguishable from AD symptoms or with inflammatory response upon resolution of molluscum. CI - (c) 2024 Novan, A Ligand Company.
