CASE ALLEGATIONS: ImmunityBio is a biotechnology company that focuses on innovating, developing, and commercializing next-generation immunotherapies. According to the complaint, ImmunityBio’s lead biologics product is Anktiva.

The ImmunityBio class action lawsuit alleges that defendants throughout the Class Period made false and/or misleading statements and/or failed to disclose that: (i) representations that “Anktiva will allow all NMIBC patients treated with Anktiva to be cancer-free for the long term, when this has not been demonstrated”; (ii) the claim that Anktiva is a cancer vaccine was false; and (iii) ImmunityBio’s Executive Chairman and Global Scientific and Medical Officer, defendant Dr. Patrick Soon-Shion, materially overstated Anktiva’s capabilities.

The ImmunityBio class action lawsuit further alleges that on March 24, 2026, a warning letter (dated March 13, 2026) from the U.S. Food and Drug Administration to CEO Richard Adcock was publicized, stating that a “TV ad and podcast misbrand[ed] Anktiva and make the distribution of the drug in violation of the Federal Food, Drug, and Cosmetic Act.” The warning letter allegedly further stated that “[t]hese 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.” On this news, the price of ImmunityBio stock fell 21%, according to the complaint.

THE LEAD PLAINTIFF PROCESS: The Private Securities Litigation Reform Act of 1995 permits any investor who purchased or acquired ImmunityBio publicly traded securities during the Class Period to seek appointment as lead plaintiff in the ImmunityBio class action lawsuit. A lead plaintiff is generally the movant with the greatest financial interest in the relief sought by the putative class who is also typical and adequate of the putative class. A lead plaintiff acts on behalf of all other class members in directing the ImmunityBio investor class action lawsuit. The lead plaintiff can select a law firm of its choice to litigate the ImmunityBio shareholder class action lawsuit. An investor’s ability to share in any potential future recovery is not dependent upon serving as lead plaintiff of the ImmunityBio class action lawsuit.
