Summary
This study tests if an injectable form of letrozole (Letrozole SIE) works as well as the standard pill (Femara) for controlling advanced breast cancer. Both groups also receive a targeted drug called ribociclib. About 300 postmenopausal women with HR-positive, HER2-negative breast cancer that has spread or cannot be removed by surgery will take part. The main goal is to see how long the cancer stays under control.
