Abstract
Up to 90% of children and adults with atopic dermatitis (AD), a chronic inflammatory skin disease, present with mild-to-moderate disease. Crisaborole Topical Ointment, 2%, is a novel, nonsteroidal, topical, anti-inflammatory, phosphodiesterase 4 inhibitor being studied for the treatment of AD. The efficacy and safety of crisaborole was assessed in 2 identically designed, multicenter, vehicle-controlled, double-blind Phase 3 studies (301 and 302) that enrolled patients ≥2 years old with mild-to-moderate AD affecting ≥5% of body surface area (BSA). Patients were randomized 2:1 to receive crisaborole or vehicle twice daily and evaluated on Days 8, 15, 22, and 29. The primary endpoint defined success in the Investigator's Static Global Assessment (ISGA) as “almost clear/1” or “clear/0” with ≥2-grade improvement from baseline at Day 29. Secondary endpoints analyzed the time to success and the percentage of patients achieving “almost clear/1” or “clear/0” on ISGA. At Day 29, more crisaborole-treated patients achieved ISGA success than vehicle (301: 32.8% vs 25.4%, P = 0.038; 302: 31.4% vs 18.0%, P < 0.001), with a greater percentage of “almost clear/1” or “clear/0” ISGA scores (301: 51.7% vs 40.6%, P = 0.005; 302: 48.5% vs 29.7%, P < 0.001). Success in ISGA scores was achieved earlier with crisaborole than vehicle (P < 0.001). Treatment-related adverse events (AEs) were usually mild and included upper respiratory tract infection (pooled data, crisaborole vs vehicle: 3.0% vs 3.0%) and application site pain (4.4% vs 1.2%). AE-related discontinuation rates were low for both groups (1.2%). 2 large Phase 3 studies demonstrated crisaborole may represent a novel, safe, and efficacious treatment for patients with mild-to-moderate AD.
