Overview
The aim of this study is to investigate the safety and efficacy of the prophylactic use of Trilaciclib in patients with non-small cell lung cancer (NSCLC) receiving platinum-based chemotherapy, so as to provide more evidence-based medical evidence for the optimal diagnosis and treatment strategy in this population.
Description
This is a single-arm, exploratory clinical study. Eligible patients were treated with Trilaciclib before the first cycle of chemotherapy, and their peripheral blood samples were tested on days 3,7,14,21±1 after chemotherapy. At the same time, the incidence of FN, the use of antibiotics, the safety, the number of patients who delayed the second cycle of treatment, the number of patients who reduced the dose of chemotherapy, the number of patients who reduced the dose of chemotherapy due to neutropenia, and the number of patients who discontinued chemotherapy were observed.

- Advanced non-small cell lung cancer without systemic chemotherapy.
- At least one tumor lesion with a maximum diameter ≥10 mm (short diameter ≥15 mm if it is a lymph node) that could be measured accurately at baseline according to RECIST1.1 criteria. Baseline tumor imaging was performed within 28 days before the first dose.
