Overview
Brief Summary
The aim of this single-arm, exploratory clinical study is to evaluate the safety and efficacy of local injection of envafolimab combined with chemotherapy in the first-line treatment of non-small cell lung cancer (NSCLC) patients, and to observe the changes of immune cells in the local immune microenvironment before and after immunotherapy, in order to find new indicators for immunotherapy evaluation.
Detailed Description
In this study, 16 patients with NSCLC were enrolled to explore the clinical effect of chemotherapy combined with local injection of Envafolimab. To determine whether the treatment of metastatic/recurrent NSCLC with Envafolimab is effective, and whether the treatment of Envafolimab combined with chemotherapy can prolong the PFS\\OS of patients with NSCLC, and to screen for a more effective treatment mode for Chinese NSCLC patients.

Intervention: Envafolimab Injection
Outcomes
Primary Outcomes
Objective Response Rate(ORR)
Time Frame: Up to 2 years
ORR is the proportion of subjects with complete response (CR) or partial response (PR), based on RECIST v1.1
Overall Survival(OS)
Time Frame: Up to 2 years
OS is defined as the time from randomization to death due to any cause.
Progression free survival(PFS)
Time Frame: Up to 2 years
Progression free survival (PFS) is defined as the time from the start of treatment until the first documentation of disease progression or death due to any cause, whichever occurs first (based on RECIST v1.1).
Secondary Outcomes
- Disease control rate (DCR)(Up to 2 years)
- Duration of response (DOR)(Up to 2 years)
- Treatment related adverse events (TRAEs)(from first dose to 30 days post the last dose)
