Abstract 3811
Background
NIN is a triple angiokinase inhibitor approved in the EU in combination with DOC for the treatment of adenocarcinoma non-small cell lung cancer patients after first-line therapy (FLT). A continuous linear correlation between overall survival (OS) benefit with NIN and the predictive marker “time from start of FLT” (TSFLT) has been observed in adenocarcinoma patients.
Methods
First, analyses were conducted of European adenocarcinoma patients, who comprise the majority of the population from the Phase III LUME-Lung 1 trial comparing NIN/DOC with placebo (PLA)/DOC (NCT00805194). Second, in order to further characterise time from FLT, analyses were conducted in adenocarcinoma populations defined by the dichotomisation at appropriate cut-points of TSFLT or progressive disease (PD) as best response to FLT. Analyses based on “time from end of FLT” (TEFLT) as described in other clinical trials were also performed.
Results
In the overall adenocarcinoma population (n = 658), both independently assessed progression-free survival (median 4.0 vs 2.8 months, hazard ratio [HR] 0.77 [95% CI 0.6–0.96]; p = 0.0193) and OS were significantly longer with NIN/DOC vs PLA/DOC (median OS [mOS] 12.6 vs 10.3 months, HR 0.83 [95% CI 0.70–0.99]; p = 0.0359). OS improved both in the overall European adenocarcinoma (n = 463; mOS 13.4 vs 8.7 months, HR 0.79 [0.65–0.97]; p = 0.0254) and in European adenocarcinoma patients with TSFLT
Conclusions
NIN plus DOC exhibits significant OS benefits in the adenocarcinoma population and a more pronounced OS benefit in patients with a shorter time since FLT and more aggressive tumours.
