ImmunityBio and certain of its executives are charged with failing to disclose material information during the Class Period, violating federal securities laws.
On March 24, 2026, a warning letter dated March 13, 2026, from the U.S. Food and Drug Administration to CEO Richard Adcock was made public, stating that a television advertisement and podcast misrepresented Anktiva and resulted in its distribution violating the Federal Food, Drug, and Cosmetic Act. The letter also reportedly noted that the violations “are concerning from a public health perspective because the promotional communications create a misleading impression that Anktiva, a treatment for a certain type of bladder cancer, can cure and even prevent all cancer.”
