What was measured
IC-DR was defined, for participants with a confirmed intracranial objective response (OR) of complete response (CR) or partial response (PR) per RECIST version 1.1, as the time from the first documentation of intracranial OR to the first documentation of intracranial progressive disease (PD) or death due to any cause, whichever occurred first. CR was defined as 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). PR was defined as at least a 30% decrease in the sum of the longest dimensions of the target lesions taking as a reference the baseline sum longest dimensions. PD was defined as at least a 20% increase (including an absolute increase of at least 5 mm) in the sum of the longest dimensions of the target lesions taking as a reference the smallest sum of the longest dimensions recorded since the treatment started, or the appearance of 1 or more new lesions.
Analysis population: Participants with brain metastases at baseline and confirmed intracranial complete response or partial response in the FA population.
Groups in this outcome
Lorlatinib
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
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.
