PAlbociclib Plus Tamoxifen for the Treatment of Hormone Receptor-positive, HER2-negative Advanced Breast Cancer Women - Asian studY
About the study
This study is conducted to evaluate the benefit of adding palbociclib in hormone receptor (HR)-positive, HER2-negative advanced or metastatic breast cancer patients, regardless of menopausal status, treated with tamoxifen (with or without goserelin) versus tamoxifen alone (with or without goserelin).
