1494PEffectiveness and safety of nivolumab in the treatment of lung cancer patients in France: Updated survival and subgroup analysis from the real-world EVIDENS study

Abstract Background The EVIDENS study aims to describe clinical characteristics and health-related quality of life (HRQoL) of lung cancer patients treated with nivolumab in real-life in France and to assess its effectiveness and safety. Methods EVIDENS is an observational, multicenter, longitudinal cohort study of adult lung cancer patients treated with nivolumab. Survival was assessed using the Kaplan-Meier method and health-related quality of life (HRQoL) was assessed using EQ-5D-3L questionnaire. Results A total of 1,462 lung cancer patients were enrolled in the study from Oct 2016 to Nov 2017 in 146 French centers. Previous reports with a 8-month minimum follow-up showed that baseline patient and tumor characteristics from EVIDENS were representative of a standard advanced NSCLC population and that nivolumab was mostly administered as a 2nd line regimen. Median PFS and median OS was 2.8 months (95% CI: 2.6-3.0) and 10 months (95% CI: 9.2-11.0), respectively. Adverse events occurred in 440 patients (31.6%), including 98 patients (7.0%) with grade 3-4 events. Concerning HRQoL, mean change of visual analog score from baseline was statistically significant at 9 and 12 months and minimal important difference was achieved at 12 months for the squamous population. The analysis presented during the congress will include updated effectiveness, safety and HRQoL data as well as subgroups of interest (e.g. brain metastasis, age, prior radiotherapy) with a 17-month minimum follow-up. Conclusions TTo date, EVIDENS is the largest prospective observational study of nivolumab in lung cancer patients confirming effectiveness and safety in the real world setting. This updated analysis provides new insights on the experience of nivolumab over a period of longer follow-up and, for the first time, in clinically important subgroups of interest.
