Camrelizumab With Chemotherapy in Adults With Medically Inoperable Early Stage NSCLC

A Pilot Study of Camrelizumab With Chemotherapy in Adults With Medically Inoperable Early Stage Non-Small Cell Lung Cancer (NSCLC)

The purpose of this study is to assess the efficacy and safety of Camrelizumab plus chemotherapy in the treatment of adult participants with medically inoperable Stage I or IIA non-small cell lung cancer (NSCLC).

This trial will evaluate the safety and efficacy of camrelizumab in combination with chemotherapy, followed by camrelizumab alone after 4-6 cycles of combination in participants with medically inoperable stage I or IIA non-small cell lung cancer (NSCLC). The primary objective of this pilot study is to determine the Camrelizumab plus chemotherapy improves progression-free survival (PFS) . All the efficacy and safety are assessed by investigator : 1) response rate (ORR), 2) disease control rate (DCR); 3) overall survival (OS), 4) PFS rate of 1-year, 2-year, and 5-year; and 5) OS rate of 1-year, 2-year, and 5-year.

Explore objective is potential biomarker associated with efficacy.
