A clinical study of camrelizumab combined with chemotherapy and sequential apatinib in the second-line treatment of patients with advanced non-small cell lung cancer.

Abstract

e21051 Background: Camrelizumab combined with chemotherapy has shown a higher efficiency and survival benefit in clinical studies of the first-line treatment of lung cancer. This study aims to observe the clinical efficacy and safety of camrelizumab combined with chemotherapy and sequential apatinib in the second-line treatment of patients with advanced non-small cell lung cancer in a real environment. Methods: This is a prospective, open, multi-center observational study that includes advanced lung cancer that is older than 18 years old, regardless of gender, with an ECOG score of 0-1, and recurrence or failure after first-line platinum-based dual-drug chemotherapy patient. Results: As of January 25, 2021, a total of 18 patients were enrolled, of which 12 were female (66.67%), 11 patients had an ECOG PS score of 1 point (61.11%), and 15 patients were stage IV (83.33%), patients, 5 patients with tissue poorly differentiation (27.78%), 55.56% of the patients had undergone immunohistochemical testing, and 66.67% of the patients had become positive for the gene. A history of radiotherapy accounted for 11.11%, and a history of surgery on the primary lesion accounted for 27.78%. Previous first-line chemotherapy options were pemetrexed combined with cisplatin (22.22%), pemetrexed combined with lobaplatin (22.22%), pemetrexed combined with carboplatin (11.11%), bevacizumab combined with Platinum dual-drug regimen (38.89%); Among the 10 patients with evaluable efficacy, 0 had CR, 2 had PR, 6 had SD, and 2 had PD. The ORR reached 20.00% and the DCR reached 80.00%. The overall incidence of adverse reactions is low, and the medication process is safe and controllable. Conclusions: In this second-line clinical study of lung cancer, most of the patients enrolled were patients with poor PS scores and later stages, but the effectiveness and safety of carrelizumab in patients with advanced lung cancer were still confirmed. The dominant population and the combined treatment plan are still being studied. Clinical trial information: ChiCTR2000034597.
