Mechanism of Action

Trilaciclib (G1T28) Hydrochloride is a small molecule inhibitor of the CDK4/6 kinases that play a critical role in cell cycle regulation and are overexpressed in many types of cancer. Trilaciclib works by selectively blocking CDK4/6 activity, which leads to a temporary arrest of cell division in rapidly dividing cancer cells.

Trilaciclib has been studied as a potential treatment for cancer in combination with chemotherapy. By temporarily inhibiting CDK4/6 activity, trilaciclib may help protect normal cells, such as immune cells, from chemotherapy-induced cell death, which can lead to an improvement in treatment response and reduced side effects. Additionally, trilaciclib may enhance the effectiveness of chemotherapy by synergistically suppressing the growth of cancer cells through the combination of chemotherapy and CDK4/6 inhibition.


Trilaciclib Hydrochloride is an investigational medication and is not yet approved for any indication by regulatory agencies such as the US Food and Drug Administration (FDA) or the European Medicines Agency (EMA).

However, it has been studied as a potential treatment for patients with small cell lung cancer (SCLC) undergoing chemotherapy. In clinical trials, trilaciclib hydrochloride was given in combination with chemotherapy to help preserve white blood cells and reduce the severity and duration of chemotherapy-induced neutropenia, which is a common side effect of chemotherapy that can lead to infections and other complications.
