Breast Cancer Drug Wins Accelerated Approval Four Months After FDA Advisers Voted Six to Three Against It
The FDA approved AstraZeneca's breast cancer drug camizestrant (Etcamah) for patients with ESR1 mutations, despite earlier advisory committee opposition. Approval was based on a trial showing improved progression-free survival. The drug is used with a CDK4/6 inhibitor and requires a specific blood test for eligibility. AstraZeneca's stock may be affected by this development.
