Abivax UC drug delivers strong remission in Phase 3, but safety signals spark caution
Abivax’s ulcerative colitis therapy obefazimod showed high remission rates in a 580-patient Phase 3 maintenance trial, with about 51% remission at both 25 mg and 50 mg doses over 44 weeks versus 10.4% with placebo, suggesting strong efficacy. However, the company reported a few cancer cases among treated patients, raising safety concerns and sending shares lower after the results were disclosed.
