Expanded Access to Trilaciclib for Patients Receiving Chemotherapy for Small Cell Lung Cancer

"Trilaciclib is a highly potent, selective, and reversible cyclin-dependent kinase 4/6 inhibitor administered intravenously prior to chemotherapy for chemotherapy-induced myelosuppression (CIM).~In patients being treated for SCLC, trilaciclib transiently maintains G1 cell cycle arrest of hematopoietic stem and progenitor cells (HSPCs) in the bone marrow, thus protecting the cells from damage by cytotoxic chemotherapy (myelopreservation). This can reduce chemotherapy-related toxicity, making chemotherapy safer and more tolerable, and also reduce the need for rescue interventions that address the effects of myelosuppression, such as growth factors or blood and platelet transfusions."
