Brief Summary

This study is a prospective, single arm phase II study aimed at patients with locally advanced or metastatic non-small cell lung cancer undergoing second-line or beyond treatment. The aim is to evaluate the bone marrow protective effect of trilaciclib before docetaxel chemotherapy for locally advanced or metastatic NSCLC.

Detailed Description

After obtaining informed consent from patients diagnosed with locally advanced or metastatic NSCLC through pathology, 33 eligible subjects who met the inclusion criteria were selected to receive the treatment regimen of trilaciclib before docetaxel chemotherapy, with a treatment period of 4 cycles.

Record the dynamic changes of whole blood cell count; Hematological toxicity, including febrile neutropenia and associated infections; Transfusion of blood products and supplementation of hematopoietic raw materials. Perform tumor imaging evaluation according to RECIST 1.1. Baseline imaging examination shall be conducted within 21 days prior to the first administration, and tumor imaging evaluation shall be conducted every 6 weeks (± 7 days) from the first study drug administration, or the frequency of imaging evaluation may be increased when there are clinical indications. The imaging examination time should follow the calendar day and should not be adjusted due to treatment delay or termination. Subjects who terminate the study drug treatment due to intolerable toxicity or other non disease progression reasons should continue to receive tumor evaluation follow-up until disease progression, withdrawal from the study, or death (whichever occurs earliest)
