a study of camrelizumab plus apatinib as consolidation therapy in non-small cell lung cancer patients treated with chemoradiotherapy

Conditions: Locally Advanced Non-Small Cell Lung Cancer

Summary: this is a phase ii, open-label, multi-centre study to determine the efficacy and safety of camrelizumab plus apatinib in participants with unresectable stage iii non-small cell lung cancer (nsclc), who have not progressed following platinum-based concurrent chemoradiation therapy (ccrt) or sequential chemoradiation therapy (scrt). this study will be conducted in china mainland.

this trial will evaluate the efficacy and safety of camrelizumab plus apatinib in participants with unresectable stage iii nsclc who have not progressed following definitive, platinum-based ccrt or scrt. the primary endpoint is progression free survival (pfs) in the intent-to-treat (itt) population. the secondary endpoints are as follows: 1) overall survival (os); 2) 1, 2, 3-year os rates; 3) pfs rates at 12-monthand 18-month; 4) objective response rate (orr), 5) duration of response (dor); 6) time to death or distant metastasis (ttdm); 7) adverse effects (aes) and severe adverse effects (saes) ;8) quality of life (qol).exploratory objective is to explore potential biomarkers associated with efficacy.
