“I am very encouraged that metastatic breast cancer patients may have a treatment option that extends survival, delays chemotherapy treatment and preserves their quality of life.”

Previously examine proven ribociclib and letrozole improved progression-free survival of postmenopausal ladies with HR+ metastatic breast most cancers within the MONALEESA-2 trial.
