The FDA issued a warning letter to ImmunityBio and founder Patrick Soon-Shiong for making false and misleading claims regarding their cancer therapy, Anktiva. The agency criticized the company for suggesting the drug treats 'all cancers' without evidence, failing to disclose required combination use with a vaccine, and downplaying serious risks. The FDA also challenged claims that the treatment renders patients 'cancer free,' stating that such assertions are not supported by clinical data.
