Letrozole-matched Placebo clinical trials

A Study Evaluating the Efficacy and Safety of Giredestrant Combined With Palbociclib Compared With Letrozole Combined With Palbociclib in Participants With Estrogen Receptor-Positive, HER2-Negative Locally Advanced or Metastatic Breast Cancer (persevERA Breast Cancer)

This study is testing a new combination of medicines, Giredestrant and Palbociclib, for advanced breast cancer. It's for people whose cancer is hormone-sensitive (ER-positive) but not HER2-positive. Researchers want to see if this new combination works better and is safer than a standard treatment.
