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

Study Overview
=================
Brief Summary
-----------------
The purpose of this expanded access protocol is to provide access to trilaciclib for chemotherapy-induced myelosuppression in patients receiving chemotherapy as a treatment for small cell lung cancer (SCLC). Patients will receive trilaciclib intravenously as a 30-minute infusion prior to chemotherapy dosing and on each day that chemotherapy is administered. Supplementary to providing access to trilaciclib, this expanded access program will also capture Real World Data to help inform subsequent trilaciclib development. Requests for access to trilaciclib will be managed by Bionical Emas. G1 Therapeutics will review eligibility of, as well as complete a medical review of, each patient access request.

Arms and Interventions

| Intervention/Treatment |
| --- |
|Drug: Trilaciclib|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.|
