Abstract 3154

Background

Nivolumab has been approved by different regulatory agencies worldwide for the treatment of nSq-NSCLC based on its superiority in Overall Survival (OS) versus docetaxel in CheckMate 057 trial. In a pre-specified subgroup analysis of the same trial, this advantage was confirmed also in KRAS-mutation+ pts but the small number precluded any definitive conclusion. The Italian nivolumab EAP for non-sq-NSCLC might represent an important source of information in that respect. The current analysis describes results of the use of nivolumab in the group of EAP pts with KRAS mutations.

Methods

Nivolumab was provided upon physicians’ request for pts aged ≥18 years who had relapsed after a minimum of one prior systemic treatment for stage IIIB/stage IV non-Sq-NSCLC. Nivolumab 3 mg/kg was administered intravenously every 2 weeks for ≤24 months. Pts included in the analysis received ≥1 dose of nivolumab and were monitored for adverse events (AEs) using Common Terminology Criteria for Adverse Events.

Results

In total, 1588 Italian pts with advanced nSq-NSCLC received at least one dose of nivolumab in the EAP across 168 sites. Among pts evaluated for KRAS mutation, 206 (39%) resulted positive. In this subgroup of pts, with a median follow-up of 7.7 months (0.1-21.2) and a median number of 8 doses (1-45), the best overall response rate (BORR) was 20%, including 2 pts with complete response and 39 pts with partial response, and the median OS was 10.7 months (8.6-12.8). These results were in line with those ones showed in the overall population (18% BORR and 11 months median OS, respectively).

Conclusions

This analysis confirms, in a real word setting and in a much larger number of pts, the efficacy of nivolumab in KRAS-positive pts in CheckMate 057. Nivolumab represents a potentially effective therapeutic option for KRAS mutation, a molecular alteration for which there is currently no direct targeted therapy.
