Study Endpoints

Primary Endpoints

Progression-Free Survival (PFS)
Randomization until progressive disease (PD) or initiation of antitumor therapy in the absence of PD or death, assessed every 6 weeks (up to 112 weeks)

PFS: Time in months from randomization to first documentation of objective disease progression as determined by independent radiology review or to death due to any cause, whichever occurred first. PFS was calculated as (first event date minus the date of randomization plus 1) divided by 30.4. Progression is defined using Response Evaluation Criteria in Solid Tumors Criteria version 1.1 (RECIST v1.1), as at least a 20% increase (including an absolute increase of at least 5 mm) in the sum of diameters of target lesions, taking as reference the smallest sum on study and/or unequivocal progression of existing non-target lesions and/or appearance of 1 or more new lesions.

Objective Response Rate
6 years

The objective response rate (ORR) as a measure of anti-tumor efficacy of oral PF-02341066 in participants with advanced NSCLC with an ALK gene translocation or inversion after failure of at least one line of chemotherapy.

Percentage of Participants With Adverse Events
6 years
