      The randomized, open-label, multipart phase 3 study CheckMate 227 (NCT02477826) demonstrated a significant progression-free survival benefit (co-primary endpoint) with first-line nivolumab+ipilimumab versus histology-based, platinum-doublet chemotherapy in patients with advanced non-small cell lung cancer (NSCLC) and high tumor mutational burden (TMB; ≥10 mutations/Mb). Patient-reported outcomes (PROs) for this population within CheckMate 227 are presented.

      Eligible chemotherapy-naïve patients had stage IV or recurrent NSCLC, ECOG performance status 0−1, and no known sensitizing EGFR/ALK alterations. PROs were assessed as an exploratory endpoint; this analysis included patients with high TMB randomized to nivolumab+ipilimumab or chemotherapy; specific outcomes included proportion of patients with disease-related symptom deterioration by 12 weeks and time to deterioration in symptoms (by Lung Cancer Symptom Scale [LCSS] Average Symptom Burden Index [ASBI]), and assessment of quality of life and overall health status (by EuroQoL-5 Dimension [EQ-5D] utility index [UI] and visual analog scale [VAS]). PROs were evaluated each cycle (Q2W, nivolumab+ipilimumab; Q3W, chemotherapy) for the first 6 months, every 6 weeks thereafter during treatment, and at follow-up visits 1/2. EQ-5D was also assessed during survival follow-up.

      PRO completion rates were ~90% at baseline and >80% for nearly all on-treatment assessments. Among patients with high TMB, fewer patients in the nivolumab+ipilimumab (n=139) versus chemotherapy (n=160) groups reported symptom deterioration by week 12, irrespective of whether they were still on therapy or had discontinued (22.3% versus 35.0%; absolute risk reduction: 12.7% [95% CI: 2.4–22.5]). Time to first deterioration (TTD) using common assessment time points (on/off treatment) was delayed with nivolumab+ipilimumab versus chemotherapy for the LCSS ASBI (hazard ratio [HR]: 0.40; 95% CI: 0.26–0.63) and 3-Item Global Index (3-IGI; HR: 0.56; 95% CI: 0.38–0.82). The estimated benefit in TTD generally favored nivolumab+ipilimumab for individual symptoms in the ASBI and each item in the 3-IGI (HRs: 0.48–0.74), except for hemoptysis (HR: 1.20), which exhibited very low burden; an advantage for nivolumab+ipilimumab was also seen in the EQ-5D VAS (HR: 0.62; 95% CI: 0.42–0.92) and UI (HR: 0.50; 95% CI: 0.34–0.73). Mean changes from baseline with nivolumab+ipilimumab showed early and clinically meaningful improvements in LCSS ASBI/3-IGI and EQ-5D VAS/UI; for patients treated with chemotherapy, symptoms and quality of life remained stable (LCSS ASBI/3-IGI, EQ-5D UI) or improved following completion of chemotherapy (EQ-5D VAS).

      Nivolumab+ipilimumab demonstrated early and sustained improvements in health-related quality of life versus chemotherapy in patients with advanced NSCLC and high TMB.
