ArQule, Inc. (Nasdaq: ARQL) and Daiichi Sankyo, Co., Ltd. (TSE 4568) announced that the independent Data Monitoring Committee (DMC) of the Phase 3 MARQUEE (Met inhibitor ARQ 197 plus Erlotinib vs Erlotinib plus placebo in NSCLC) trial recommended the study be stopped early following a planned interim analysis, when they concluded that the study would not meet its primary endpoint of improved overall survival.

Although the interim analysis showed a statistically significant improvement in progression-free survival (PFS) in the intent-to-treat (ITT) population, this benefit did not carry over to overall survival. There were no safety concerns identified by the DMC to Daiichi Sankyo or ArQule during this interim analysis.

MARQUEE is a randomized, double-blind, controlled pivotal trial to evaluate the investigational selective MET inhibitor, tivantinib (ARQ 197), in combination with erlotinib in previously treated patients with locally advanced or metastatic, non-squamous NSCLC.

ArQule and Daiichi Sankyo are providing information regarding the study discontinuation to health authorities and those clinical investigators participating in studies of tivantinib. Data from this study will be presented at an upcoming scientific meeting.

"We are disappointed that the MARQUEE trial did not provide statistically significant results for overall survival in a disease and treatment setting which remains a major unmet medical need," said Paolo Pucci, chief executive officer of ArQule.
