AstraZeneca Provides Update On SERENA-4 Phase III Trial Of Etcamah In Combination With Palbociclib In Upfront First-Line Advanced ER-Positive Breast Cancer

AstraZeneca's SERENA-4 Phase III trial of Etcamah (camizestrant) with palbociclib did not meet the primary endpoint of progression-free survival in advanced ER-positive breast cancer, though a numerical improvement was observed. The trial compared the combination to anastrozole with palbociclib. Etcamah's safety profile was consistent with known profiles, and data will be shared later. Etcamah is approved in combination with CDK4/6 inhibitors for certain breast cancer treatments.
