Atopic dermatitis (AD) is a highly pruritic inflammatory skin disease. Two phase 3 studies (TRuE-AD1/TRuE-AD2) enrolled patients aged ≥12 years with AD for ≥2 years, an Investigator’s Global Assessment (IGA) score of 2/3, and 3%–20% affected body surface area. Patients (total N = 1249; median age, 32 years) were randomized (2:2:1) to twice-daily 0.75% ruxolitinib (Janus kinase [JAK] 1/JAK2 inhibitor) cream, 1.5% ruxolitinib cream, or vehicle cream for 8 weeks of double-blind treatment, and thereafter continued in a long-term, 44-week period of the studies. In this pooled analysis, mean percentage change from baseline in Eczema Area and Severity Index (EASI) anatomic region subscores is reported up to Week 8 (n = 1208). For the head and neck region, patients applying 0.75%/1.5% ruxolitinib cream (vs vehicle) achieved mean improvements of 59.3%/55.8% (vs 13.4%), 70.4%/71.3% (vs 22.4%), and 70.0%/78.7% (vs 45.0%) at Weeks 2, 4, and 8, respectively (all P \u3c.0001). Results were similar for the upper limbs region (48.5%/54.7% [vs 13.3%], 66.6%/70.3% [vs 25.0%], and 73.5%/74.9% [vs 35.1%] all P \u3c.0001). For the trunk region, patients achieved mean improvements of 49.8%/60.0% (vs 12.1%), 67.3%/73.8% (vs 15.0%), and 72.7%/81.0% (vs 15.6%) at Weeks 2, 4, and 8, respectively (all P \u3c.0001). Similar results were observed for the lower limbs region (46.0%/48.2% [vs 16.3%], 65.9%/66.2% [vs 13.9%], and 76.3%/74.9% [vs 39.8%]; all P \u3c.0001). Ruxolitinib cream was well tolerated, with an adverse event profile similar to vehicle. In summary, ruxolitinib cream demonstrated significant improvements vs vehicle in patients with AD across anatomic regions as early as Week 2
