Why ImmunityBio Stock Slumped on Monday
2026-04-06 20:01:34 ET
Cancer-focused biotech ImmunityBio (NASDAQ: IBRX) hasn't been in the good graces of a top regulator lately, and the latest development in that story on Monday was discouraging for investors. Numerous shareholders sold out of the stock to sink it by slightly over 3% that trading session.
That regulator is the U.S. Food and Drug Administration (FDA). In mid-March, it sent ImmunityBio a warning letter stating that the biotech 's recent promotional materials for cancer immunotherapy drug Anktiva were "false or misleading."
