IBRX shares lost $1.98 per share, a 21% decline, closing at $7.42 on March 24, 2026, after an FDA Warning Letter exposed allegedly false promotional claims. The window to apply for lead plaintiff closes on May 26, 2026.
January 19, 2026: The Podcast That Triggered Regulatory Scrutiny
The class period opens on the date ImmunityBio's Executive Chairman appeared on The Sean Spicer Show podcast and made sweeping claims about ANKTIVA, the Company's lead biologic product. According to the lawsuit, the broadcast suggested that ANKTIVA could treat "all cancers," was represented as a "cancer vaccine," and was characterized as a simple subcutaneous injection. The podcast was linked on the Company's corporate website, amplifying its reach to investors and patients.
January 19, 2026 through March 12, 2026: The Period of Alleged Artificial Inflation
During these weeks, the action contends that IBRX shares traded at artificially inflated prices. Investors purchased stock without knowledge that the promotional claims allegedly violated federal drug promotion regulations. ANKTIVA was approved solely for a specific type of bladder cancer. According to the complaint, bladder cancers represented only an estimated 4.2% of new cancer cases in 2025. The drug's efficacy was established only in combination with BCG, and a cohort studying ANKTIVA as a single agent was stopped early for futility.
March 13, 2026: The FDA Warning Letter Is Issued
The FDA's Office of Prescription Drug Promotion issued a Warning Letter to ImmunityBio's CEO at the Company's Culver City, California facility. The letter determined that both a TV advertisement and the January podcast were "false or misleading" and that the promotional materials misbranded ANKTIVA in violation of the Federal Food, Drug, and Cosmetic Act. The FDA characterized the claims as "especially concerning from a public health perspective."
March 24, 2026: The Corrective Disclosure Reaches Investors
The Warning Letter was publicized, and Bloomberg reported the story under the headline "ImmunityBio Plunges After Getting FDA Warning on Cancer Drug." IBRX shares fell 21% in a single session. The Company subsequently removed the podcast from its website.
