Abivax (NASDAQ:ABVX) ADS gain $2.3B after obefazimod safety news; Paris session yet to start
Abivax S.A. is set for a lagged Paris opening after its U.S. ADS jumped in after-hours trading. Investors reacted to new clinical data on obefazimod, Abivax’s ulcerative colitis drug. The latest news hits late, but the drop earlier this month wasn’t about whether the drug works. It was about the potential cancer risk and what that could mean for the drug’s label.
