ABVX Stock Clocks Worst Day Ever On Malignancy Signal For Drug: ‘Pharma Bro’ Says ‘GLPs Are Doing Fine’ After Similar Fears
Abivax SA (ABVX) shares fell 44% to a worst-ever day after late-stage ulcerative colitis trial results for obefazimod showed ~51% clinical remission at week 44 vs 10.4% on placebo, but reports of non-melanoma skin cancers and other malignancies in older patients raised safety concerns. Jefferies cut its target to $90 from $160 and downgraded to Hold; Wedbush raised to Neutral with $90 target. Martin Shkreli said GLP-1 fears later proved unfounded.
