What was measured

Disease control: participants with CR, PR, or SD according to RECIST v1.1. CR: disappearance of all target and non-target lesions and normalization of tumor marker level, all lymph nodes must be non-pathological in size (\<10 mm short axis). PR: at least 30 % decrease in sum of diameters of target lesions, taking as reference the baseline sum diameters persistence of one or more non-target lesion(s) and/or maintenance of tumor marker level above the normal limits. SD: neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD, taking as reference the smallest sum diameters while on study. PD: 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.

Analysis population: FAS included all participants who were randomized to study treatment.

Groups in this outcome

Crizotinib

Crizotinib (PF-02341066) 250 mg (administered as two 100-mg tablets and one 50-mg tablet) orally twice daily continuously in 21-day cycles. Treatment was continued until disease progression, unacceptable toxicity or withdrawal of consent occurred.

Chemotherapy

Pemetrexed 500 mg/m\^2 intravenous infusion over 10 minutes or docetaxel 75 mg/m\^2 intravenous infusion over 1 hour on Day 1 of 21-day cycle, as per investigator discretion. Treatment was continued until disease progression, unacceptable toxicity or withdrawal of consent occurred.
