What was measured

TTR was defined as the time from randomization to first documentation of objective tumor response (CR or PR) according to RECIST v1.1 determined by IRR. CR: complete disappearance of all target lesions and non-target disease. All nodes, both target and non-target, must decrease to normal (short axis \<10 mm). No new lesions and disappearance of all non-target lesions. PR: \>=30% decrease taking as reference the baseline sum of lesion dimensions. Short axis was used in sum for target nodes, while longest diameter was used in sum for all or target lesions. No clear progression of non-target disease. No new lesions.

Analysis population: The FA population included all participants who were randomized with study treatment assignment designated according to the initial randomization. Here N signifies participants with objective tumor response and were evaluable for this outcome measure.

Groups in this outcome

Crizotinib

Crizotinib 250 mg capsule, orally twice daily was administered in treatment cycle of 21 days. Participants could continue crizotinib treatment beyond the time of RECIST v1.1 defined PD, as determined by IRR, at the discretion of the investigator if the participant was perceived to be experiencing clinical benefit.

Chemotherapy

Standard doses of chemotherapy (pemetrexed/cisplatin or pemetrexed/carboplatin) were administered intravenously on Day 1 of each cycle for a maximum of 6 cycles. Pemetrexed 500 mg per meter square (m)\^2 IV infusion according to standard of care was administered over 10 min; either cisplatin 75 mg/m\^2 IV infusion was administered approximately 30 min after the end of the pemetrexed infusion or carboplatin was administered at a dose calculated to produce an AUC of 5 or 6 mg\*min/mL, approximately 30 min after end of pemetrexed infusion.
