Sept 11 (Reuters) – AstraZeneca’s breast cancer drug failed to meet the ​main goal of ‌improving progression-free survival during a late-stage trial, it said on Friday, marking a ‌setback ​for the recently ⁠approved treatment.

U.S.-listed ⁠shares of AstraZeneca fell 3% in aftermarket trading.

The drug, branded as Etcamah, ​when tested in combination with another cancer ⁠treatment palbociclib, ⁠only showed a ​numerical improvement in previously untreated ​patients with a form ‌of advanced breast cancer, the company said.

AstraZeneca said the trial data ⁠will be shared in due course.

Last week, the U.S. Food ⁠and ‌Drug Administration gave ⁠accelerated approval for ​Etcamah ‌to be used ​together with ⁠certain targeted cancer medicines known as CDK4/6 inhibitor.
