Abivax's plunge reflects the loss of an M&A premium on safety signals, not a clinical failure, and more downside is possible near term. Obefazimod's ulcerative colitis efficacy is strong: about 51% remission in 44-week maintenance at 25mg and 50mg versus 10.4% for placebo. But prostate, breast and colorectal cancer or dysplasia cases at 50mg, though judged unrelated, could weigh on FDA review, labeling and sales. Waiting for FDA meetings and detailed October data is safer than bottom-fishing. x.comÂ
