Breast cancer drug from AstraZeneca, Daiichi hits goal in late-stage trial

LONDON — AstraZeneca said Friday an experimental drug tamped down the progression of a certain type of breast cancer in a Phase 3 trial, a win for the company after the same drug produced underwhelming results in a lung cancer trial over the summer.

The drug, called datopotamab deruxtecan or Dato-DXd for short, succeeded on one of its primary endpoints of improving progression-free survival compared to chemotherapy in certain breast cancer patients who had previously been treated with other therapies.

AstraZeneca, which is developing Dato-DXd with partner Daiichi Sankyo, said that the data for the other primary endpoint of overall survival were not “mature” as of this interim analysis, but that there was a positive trend. The trial is continuing.
