ImmunityBio (NASDAQ:IBRX) shares increased by 3% on Monday following the submission of a comprehensive response to the U.S. Food and Drug Administration. The response addresses compliance issues raised by the FDA's Office of Prescription Drug Promotion regarding the company's promotional materials.
The biotech company acted on concerns related to a television advertisement and a podcast. ImmunityBio confirmed the advertisement was never aired or disseminated.
