The CEO mentioned that the 375-pts event took place sometimes in mid July 2012.
"The mOS for the erlotinib control arm is assumed to be 7 months."
The PhII placebo-arm had just 6% of KRAS-mutant pts. These pts have just 2.5 months mOS in the 1st-line pts. There are ~25% of KRAS-mutant pts in a general NSCLC population. ARQL mentioned that PhIII pts population would model the "real life" or mKRAS is expected to be ~ 25%.
MARQUEE's much higher mKRAS population could bring the erlotinib control arm mOS to under 6 month.
My "on a top of an envelop" calculations for the 7-months the erlotinib control arm mOS would bring the the 375-pts event to mid August for the 2-months control/drug arms mOS separation. The 6-months erlotinib control arm mOS would bring the the 375-pts event to mid July for the same 2-months control/drug arms mOS separation.
PS It is very puzzling to me why MARQUUE trial has mEGFR pts population.
