Background: We aimed to evaluate clinical and quality of life (QoL) outcomes of Nivo as 2+ line treatment in NSCLC pts within expanded access program and real world practice. Methods: Adult pts with advanced refractory NSCLC were enrolled in 11 centers in RF. All the pts received Nivo 3 mg/kg q2w. Tumor response was assessed using RECIST v. 1.1, adverse events (AEs) – NCI CTCAE v3.0. Patients filled out RAND SF-36 and ESAS-R at baseline, 1, 3, 6 and 12 mos after treatment start. Overall survival (OS) and progression-free survival (PFS) curves were evaluated by the Kaplan-Meyer method and compared by the log-rank test. GEE method was used for QoL analysis; χ2 test – for disease control rate (DCR) comparison. Results: The preliminary analysis was performed in the group of 200 pts with median follow-up 7.4 mos (65% – males; median age – 62 y.o.; ECOG 0-1 – 81%; former/current smokers – 70.5%; non squamous NSCLC – 64%; ≥2 lines of previous treatment – 53%, bone mts – 22%). DCR was revealed in 60.3% pts (108/179 pts, median first evaluation – 2.1 mos); 13 pts died before first response evaluation; 8 pts were not evaluated for response at cut-off. DCR was higher in squamous NSCLC (66%, squamous vs 51%, non squamous; χ2 = 4.0, p = .045). Median OS – 11.5 mos (95%CI 8.3–14.7), median PFS – 4.2 mos (95%CI 3.5–4.9). Patients with poor ECOG (ECOG 2-3 vs 0-1: median OS – 5.6 mos vs 12.4 mos, median PFS – 2.7 vs 4.2 mos) and those with bone mts (with mts vs without mts: median OS – 5.0 vs 12.5 mos, median PFS – 2.8 vs 4.1 mos) had worse survival; log-rank p < 0.05. QoL improved during 6 mos of treatment in more than 50% pts; average increase by 60% of mean Integral QoL Index (IQoLI) at different time-points was observed. Upon GEE, IQoLI improvement during 12 mos was revealed (p < .0001). The severity of fatigue and dyspnea, which had the highest burden at base-line, decreased during 6 mos of treatment in more than 50% and 30% pts, consequently. AEs were registered in 32.7% pts (median of Nivo treatment – 2 mos); among them 17 pts had grades 3-4 AEs; 5 pts – SAEs. Conclusions: Preliminary results of this study support the acceptable efficacy and safety of Nivo in NSCLC pts. Nivo treatment leads to meaningful QoL improvement and decrease of symptom burden in this patient population.
