AstraZeneca and Daiichi Sankyo’s TROP2-directed antibody-drug conjugate (ADC) has again failed to improve overall survival (OS) in a phase 3 trial. The latest miss happened in breast cancer, a setting in which Gilead’s rival Trodelvy significantly improved OS in a prior late-phase study.

AstraZeneca and Daiichi Sankyo have reported results from the TROPION-Breast01 Phase III clinical trial of datopotamab deruxtecan (Dato-DXd) for breast cancer.

AstraZeneca Plc said an experimental cancer drug it’s developing with Daiichi Sankyo Co. did not help breast cancer patients live longer than chemotherapy.

AstraZeneca said on Monday its experimental precision drug developed with Daiichi Sankyo did not significantly improve overall survival for patients with a type of breast cancer in a late-stage trial.
