SAN FRANCISCO and SUZHOU, China, May 27, 2024 /PRNewswire/ — Innovent Biologics, Inc. (“Innovent”) (HKEX: 01801), a world-class biopharmaceutical company that develops, manufactures and commercializes high quality medicines for the treatment of cancer, metabolic, autoimmune and other major diseases, today announced that picankibart (R & D code: IBI112), a recombinant anti-interleukin 23p19 subunit (IL-23p19) antibody injection, has met all the primary endpoints and key secondary endpoints in the Phase 3 registrational study (CLEAR-1) in Chinese subjects with moderate to severe plaque psoriasis.
CLEAR-1 is global the first Phase 3 registration study in IL-23p19 class that reported over 80% of subjects achieved PASI 90 after 16 weeks of treatment in psoriasis patients. Innovent plans to submit a new drug application (NDA) for picankibart in the treatment of psoriasis to the Center for Drug Evaluation (CDE) of National Medical Product Administration (NMPA).
Dosing interval set to 12 weeks
CLEAR-1 (NCT05645627) is a multicenter, randomized, double-blind, placebo-controlled Phase 3 study to evaluate the efficacy and safety of picankibart in subjects with moderate to severe plaque psoriasis. A total of 500 subjects were enrolled and randomized in a 1: 2: 2 ratio to receive placebo or picankibart 200 mg every 4 weeks at week 0, 4 and 8 followed by 200 mg or 100 mg every 12 weeks. Co-primary endpoints were the proportion of subjects achieving ≥ 90% improvement from baseline Psoriasis Area and Severity Index score (PASI 90) and the proportion of subjects achieving a static Physician’s Global Assessment (sPGA) score of clear (0) or almost clear (1) at week 16.
The co-primary endpoints were successfully met, showing a rapid and significant efficacy of picankibart
The study results showed that co-primary endpoints of CLEAR-1 were successfully met: at week 16, significantly higher proportion of subjects receiving picankibart achieved PASI 90 and sPGA 0 or 1 compared with placebo (80.3% vs. 2.0% for PASI 90 and 93.5% vs. 13.1% for sPGA 0/1, both p
