Lorlatinib monotherapy at the recommended Phase 2 dose of 100 mg, was administered orally once daily (QD) at approximately the same time of the day on a continuous daily dosing schedule. Each treatment cycle was defined as 28 days. Treatment continued until confirmation of RECIST version 1.1 defined disease progression assessed by the blinded independent central review (unless clinical benefit was still achievable), participant refusal, participant lost to follow-up, unacceptable toxicity, death, or the study was terminated by the sponsor, whichever occurred first. | Crizotinib monotherapy at the registered dose of 250 mg, was administered orally twice daily (BID) at approximately the same time in the morning and evening (12 hours apart) on a continuous daily dosing schedule. Each treatment cycle was defined as 28 days. Treatment continued until confirmation of RECIST version 1.1 defined disease progression assessed by the blinded independent central review (unless clinical benefit was still achievable), participant refusal, participant lost to follow-up, unacceptable toxicity, death, or the study was terminated by the sponsor, whichever occurred first. |
