$IBRX Lawsuit: ImmunityBio, Inc. Sued for Securities Fraud; Investors Should Contact Block ...

Investors allege ImmunityBio made false claims about Anktiva as a cancer vaccine, causing a 21% stock drop after FDA flagged misleading promotions.

  • On Friday, law firms announced class action lawsuits against ImmunityBio, Inc. and its executives over alleged misleading statements regarding Anktiva, a bladder cancer drug. Investors have until May 26, 2026, to seek lead plaintiff status.
  • A March 13 warning letter from the U.S. Food and Drug Administration to CEO Richard Adcock alleged promotional materials "misbrand Anktiva" and created a "misleading impression" that the drug could cure all cancer.
  • According to the lawsuit, Executive Chairman and Global Scientific and Medical Officer Dr. Patrick Soon-Shiong materially overstated Anktiva's capabilities, falsely claiming the drug was a cancer vaccine and would keep patients "cancer-free for the long term."
  • The litigation covers purchasers of ImmunityBio securities between January 19, 2026, and March 24, 2026. Investors may contact the Rosen Law Firm or Faruqi & Faruqi to join through contingency fee arrangements.
  • Whistleblowers providing original information to the Securities Exchange Commission may receive rewards of up to 30% of successful recoveries. Investors need not serve as lead plaintiff to participate in potential future settlements.
