While CDK4/6 inhibitors (CDK4/6i) are often initially successful in many breast cancer subtypes, often resistance develops and other subtypes like triple-negative breast cancer (TNBC) fail to respond. Here, the authors demonstrate that the CDK2 inhibitor BLU-222, alone or with CDK4/6i, restores cell-cycle control via p21/p27 induction overcoming resistance in preclinical models of breast cancer, including TNBC.
