A Study of Local Envafolimab Injection Combined With Chemotherapy in Non-small Cell Lung Cancer

A Single-arm, Exploratory Clinical Trial Investigating the Efficacy of Local Envafolimab Injection Under Fiberoptic Bronchoscopy Combined With Chemotherapy in Non-small Cell Lung Cancer

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.

Study Overview

• Status: Recruiting
• Conditions: NSCLC
• Intervention / Treatment: Drug: Envafolimab Injection

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.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Overall Survival(OS)	OS is defined as the time from randomization to death due to any cause.	Up to 2 years
Objective Response Rate(ORR)	ORR is the proportion of subjects with complete response (CR) or partial response (PR), based on RECIST v1.1	Up to 2 years
Progression free survival(PFS)	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).	Up to 2 years

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Disease control rate (DCR)	DCR is defined as the proportion of subjects with CR, PR, or SD based on RECIST v1.1.	Up to 2 years
Duration of response (DOR)	DOR is defined as the duration from the first documentation of objective response to the first documented disease progression (based on RECIST v1.1) or death due to any cause, whichever occurs first.	Up to 2 years
Treatment related adverse events (TRAEs)	The incidence and severity of TRAEs graded according to NCI-CTCAE v5.0	from first dose to 30 days post the last dose
