AC-201 Shows Strong Phase 2 Results in Psoriasis Trial
- Accropeutics announced positive results on May 20, 2025, from a multicenter, randomized, double-blind Phase 2 trial of AC-201 in 145 Chinese patients with moderate-to-severe plaque psoriasis.
- The study evaluated the efficacy and safety of a novel small-molecule TYK2/JAK1 inhibitor administered orally in patients with moderate-to-severe plaque psoriasis, using measures such as PASI-75 and sPGA scores at 12 weeks compared to placebo.
- All three dosing groups met the primary and key secondary endpoints with PASI-75 response rates well above placebo , including a 20% PASI-90 at 25mg BID and 71.4% sPGA-0/1 at 50mg BID doses.
- AC-201 showed no serious adverse events or discontinuations, was generally well tolerated, with most adverse events mild or moderate and common events including upper respiratory infections and hypertriglyceridemia.
- The demonstrated efficacy and safety of AC-201 support Accropeutics' intention to move forward with Phase 3 trials targeting psoriasis and other immune-related conditions, as highlighted by CEO Dr. Xiaohu Zhang.
