API Description: Lerociclib (G1T38) is an oral CDK4/6 inhibitor used primarily for treating Hormone Receptor-positive, HER2-negative (HR+/HER2-) advanced or metastatic breast cancer, especially after progression on prior endocrine therapy, often combined with fulvestrant to arrest the cell cycle and slow tumor growth. It works by blocking CDK4/6 proteins, preventing cancer cell proliferation with a generally good safety profile, showing significant progression-free survival benefits in clinical trials like LEONARDA-1, and offering a new option for endocrine-resistant cases.
