About Trilaciclib (G1T28) 
Trilaciclib is a short-acting CDK4/6 inhibitor in development to preserve hematopoietic stem cells and enhance immune system function (myelopreservation) 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. The company recently announced positive Phase 2a topline data showing myelopreservation benefits in newly diagnosed, treatment-naive small cell lung cancer (SCLC) patients (NCT02499770). There are three additional ongoing trilaciclib trials: a trial in previously treated SCLC patients (NCT02514447), a trial in patients with triple-negative breast cancer (NCT02978716), and a trial in combination with Tecentriq® and chemotherapy in SCLC patients (NCT03041311).

About G1T38
G1T38 is a potential best-in-class oral CDK4/6 inhibitor being developed for use in combination with other targeted therapies in multiple oncology indications. Preclinical data presented at the American Association for Cancer Research 2016 Annual Meeting and published in Molecular Cancer Research and Oncotarget demonstrated the compound’s differentiation from other CDK4/6 inhibitors.

G1T38 is currently being evaluated in two Phase 1/2 clinical trials: a trial in combination with Faslodex® for people with estrogen receptor-positive, HER2-negative breast cancer (NCT02983071), and a trial in combination with Tagrisso® for people with EGFR-mutant non-small cell lung cancer (NCT03455829).
