About Trilaciclib (G1T28)

Trilaciclib is a potential first-in-class short-acting CDK4/6 inhibitor in development to preserve hematopoietic stem cells and enhance immune system function during chemotherapy. Trilaciclib is administered intravenously prior to chemotherapy and has the potential to significantly improve treatment outcomes.

Trilaciclib is being evaluated in four randomized Phase 2 clinical trials: a study in newly diagnosed, treatment-naive small-cell lung cancer (SCLC) patients (NCT02499770), a study in previously treated SCLC patients (NCT02514447), a study in combination with atezolizumab and chemotherapy in SCLC patients (NCT03041311) and a study in patients with triple-negative breast cancer (NCT02978716).
