About
The aim of this prospective, randomized, multicenter, open-label, phase II study is to test if chemotherapy can be replaced by the combination of ribociclib plus letrozole as a neo-adjuvant therapy for patients with non-metastatic primary luminal breast cancer.
Full description
Based on Ki67 levels after two weeks of initial letrozole treatment in postmenopausal patients with hormone receptor positive, HER2 negative, stage II/III breast cancer, patients are either advised to continue letrozole treatment (if Ki67 <1%) or will be randomized between standard chemotherapy (AC-T) or ribociclib in combination with letrozole (if Ki67 ≥1%).
