clinical study of anlotinib in maintenance treatment of advanced nsclc

Conditions: Nonsmall Cell Lung Cancer

Summary: based on the need of clinical practice of maintenance therapy for advanced nsclc and the reliable data of third-line treatment for non-small cell lung cancer, the investigators designed a clinical study of antinil hydrochloride versus pemetrexed in maintenance therapy for advanced nsclc to prospectively evaluate the efficacy of antinil hydrochloride in maintenance therapy for advanced nsclc. value, to provide a scientific basis for prolonging the survival time of patients with advanced nsclc, improving the quality of life of patients in the course of treatment, and optimizing treatment strategies to a greater extent.

this study is planned to be carried out in jiangsu regional multi-center. 83 cases are preliminarily expected to be included. the study started in december 2018 and ended in december 2019. it is expected that the trial will end in december 2020. in the absence of such situations as withdrawal of informed consent, intolerance of drug toxicity and side effects, or inappropriateness for further trials, each participant's expected time for research and treatment will continue until radiographically confirmed tumor progression occurs.
