Clinical development
In a September 11, 2026 announcement, AstraZeneca said its SERENA-4 Phase III trial of Etcamah, or camizestrant, combined with palbociclib did not meet its primary endpoint of statistically significant improvement in progression-free survival. The company said a numerical improvement was observed.
The trial evaluated the combination against anastrozole combined with palbociclib in patients with estrogen receptor-positive, HER2-negative advanced breast cancer who had not received systemic treatment for advanced disease. AstraZeneca said the global trial enrolled 1,371 adults and that the safety profile was consistent with the known safety profile of each medicine, with no new safety concerns identified.
