Astria Therapeutics (NASDAQ:ATXS) has initiated a Phase 1a clinical trial of STAR-0310, a high affinity monoclonal antibody OX40 antagonist for treating atopic dermatitis (AD). The trial will evaluate safety, tolerability, pharmacokinetics, and immunogenicity in approximately 40 healthy adult participants.
The randomized, double-blind, placebo-controlled single ascending dose trial is expected to provide early proof-of-concept results in Q3 2025. Preclinical results show STAR-0310 has significantly less antibody-dependent cellular cytotoxicity compared to rocatinlimab, a competing OX40 antagonist in Phase 3 development. STAR-0310 demonstrates a longer mean half-life of 26 days in cynomolgus monkeys versus 10-14 days for typical non-half-life extended IgG1 antibodies, while maintaining comparable potency to rocatinlimab.
