Phase 2 Study of the Safety, Efficacy, and Pharmacokinetics of G1T28 in Patients with Metastatic Triple Negative Breast Cancer Receiving Gemcitabine and Carboplatin Chemotherapy
This is a study to investigate the potential clinical benefit of trilaciclib (G1T28) in preserving the bone marrow and the immune system, and enhancing chemotherapy antitumor efficacy when administered prior to carboplatin and gemcitabine (GC therapy) for patients with metastatic triple negative breast cancer.
Primary Objective: Assess the safety and tolerability of G1T28 administered with GC therapy. Secondary Objectives: Assess tumor response and duration of response based on RECIST, Version 1.1. Assess PFS and OS. Assess dose intensity of gemcitabine and carboplatin. Assess the PK profile of G1T28. Assess the PK profile of gemcitabine and carboplatin when administered with G1T28. Assess the hematologic profile (kinetics and incidence/duration/frequency of toxicities) of G1T28 administered with GC therapy. Assess the incidence of febrile neutropenia. Assess the incidence of infections. Assess the utilization of RBC and platelet transfusions. Assess the utilization of hematopoietic growth factors. Assess the utilization of systemic antibiotics. Assess the incidence of chemotherapy dose reductions and dose interruptions overall. Assess the incidence of Grade 2 or greater nephrotoxicity. Determine the dose schedule of G1T28 administered with GC therapy. Exploratory Objectives: Assess the incidence of mucositis. Assess the incidence of alopecia. Assess the incidence of fatigue. Assess patient-reported QOL. Assess immunologic markers.
