      Background

      Crizotinib was registered for ALK+ NSCLC in 2013 and recently for ROS1+ stage IV NSCLC. To generate high evidenced-based knowledge and to prevent off-label use, the French National Cancer Institute (INCa) launched the AcSé Program: equal access to tumor molecular diagnosis including an exploratory phase II trial. AcSé allows nationwide safe and controlled access to crizotinib off-label.

      Biomarkers were identified with INCa molecular genetic platforms. Patients with amplification [amp] MET or mutation [mut] MET or translocation [tlc] ROS1 advanced NSCLC and not eligible for any other trial, were proposed crizotinib 250 mg BID. Tumor response was evaluated every 2 months (mo) using RECIST v1.1. The primary endpoint was the objective response rate (ORR) at 2 mo (complete + partiale response). A two-stage Simon design was applied to each cohort. Median and 95% confidence interval (CI) was estimated through Kaplan-Meier for progression-free survival (PFS), overall survival (OS), and response duration. Response duration was the delay between CR/PR and first progression/death or last follow-up.

      From 08/2013 to 03/2018, 5407 patients from 186 centers entered the biomarker program. Tumor alterations found in patients were: ROS1 tlc in 77/4050; MET amp (≥6 copies/diploid genome) in 251/4171; MET mut in 76/1007.

      Overall, 90 patients (median age, 63 years [30–92]) received crizotinib 250 mg BID.

      73 grade ≥3 adverse events (AEs) or SAE were reported in 70/90 patients. Grade ≥3 AEs were: hematologic toxicities (23%) including neutropenia (11%), and general disorders (16%) including fatigue (10%).

      This study confirms the excellent response rate of crizotinib in the ROS1+ population. Response rate in the MET mut population is comparable to the MET amp population. In addition, the response rate to crizotinib in the MET mut population is lower than that in the PROFILE 1001 study. The tolerance profile is good as previously reported.
