Federal health officials have issued a warning about controversial statements made by biotech billionaire Dr. Patrick Soon-Shiong about one of his company's cancer drugs
WASHINGTON -- Federal health officials issued a warning Tuesday over misleading statements made by biotech billionaire Dr. Patrick Soon-Shiong, who recently told podcast listeners that his company's bladder cancer drug may be able to treat, cure or even prevent other types of cancers.
The warning letter from the Food and Drug Administration takes issue with a TV advertisement and a separate podcast episode promoting Anktiva, the lead product of ImmunityBio Inc. The drugmaker is one of several biotech firms acquired by Soon-Shiong, who also owns the Los Angeles Times.
Company shares fell more than 24% in trading Tuesday after the FDA warning posted online.
Anktiva was approved by the FDA in 2024 for patients with a hard-to-treat form of bladder cancer. ImmunityBio has been working to win FDA approval to expand the drug's use to a number of other conditions, including forms of lung and pancreatic cancer.
Soon-Shiong's controversial statements came during a January episode of The Sean Spicer Show podcast titled: “Is the FDA blocking life-saving cancer treatments?”
