Corvus Pharmaceuticals’ Phase I Soquelitinib Achieves 72% EASI Reduction and 75% EASI 75 Rate
Corvus’s Phase I Cohort 4 of 200 mg soquelitinib achieved a mean 72% EASI reduction at eight weeks versus 40% for placebo, with 75% of patients reaching EASI 75. The study reported no new safety signals, and Corvus plans a 200-patient Phase II atopic dermatitis trial starting in Q1 2026.
1. Corvus Completes Upsized Public Offering Raising Approximately $201.2 Million

2. New Phase I Data Highlight Soquelitinib’s Efficacy and Durability in Atopic Dermatitis
In a blinded, placebo-controlled Phase I study of soquelitinib in moderate-to-severe atopic dermatitis, Corvus reported that 24 patients in Cohort 4 treated with 200 mg twice daily achieved a mean 72% reduction in EASI score at eight weeks versus 40% for placebo (p=0.035). Response rates included EASI 75 in 75% of patients, EASI 90 in 25%, and IGA 0/1 in 33%, with 11 of 12 treated patients reaching EASI 50. Two placebo patients required rescue medication, while none in the active arm did. Durable disease control was observed post-treatment, extending beyond 118 days in earlier cohorts without additional drug. Among patients with prior systemic therapy—35% across cohorts and 50% in Cohort 4—efficacy mirrored that in treatment-naïve individuals, whereas placebo arms fared worse. Safety remained favorable with no significant laboratory abnormalities, hepatic issues or infection rate differences versus placebo. Corvus plans a 200-patient Phase II trial in Q1 2026 with multiple dosing arms over 12 weeks, alongside planned Phase II studies in hidradenitis suppurativa and asthma and an ongoing Phase III T-cell lymphoma registration trial.
