On April 30, 2026, advisers voted against the benefit-risk profile of AstraZeneca PLC’s camizestrant for first-line treatment of advanced hormone receptor–positive (HR+) breast cancer in combination with a CDK4/6 inhibitor. AstraZeneca said it would continue working with U.S. regulators on the review.
Advisory Panel Vote and Trial Design Concerns
The FDA Oncologic Drugs Advisory Committee (ODAC) voted 6-3 against camizestrant’s benefit-risk profile. Most panel members concluded the data did not support a favorable recommendation, citing concerns about the trial’s design. They said methodological issues undermined confidence in the evidence submitted.
Candidate Profile and Regulatory Outlook
Camizestrant is an experimental oral therapy developed for advanced HR+ breast cancer. AstraZeneca sought approval for its use as a first-line treatment alongside a CDK4/6 inhibitor. The advisory panel’s recommendation is non-binding; the FDA retains authority over the final approval decision.
The negative vote increases near-term regulatory uncertainty for camizestrant. The company’s ability to address the advisers’ trial design concerns through additional data, reanalysis, or other responses will shape the FDA’s next steps. AstraZeneca plans to continue collaborating with regulators as the review progresses.
