Crizotinib is a first-generation ALK tyrosine kinase inhibitor (ITK-ALK). It is the standard first-line treatment for patients with advanced NSCLC with ALK gene rearrangement. Alectinib, ceritinib and brigatinib are second-generation ITK-ALK. They have been shown to be effective in the first line of treatment in randomized trials. Alectinib has shown superiority to crizotinib as the first line of treatment in three randomized therapeutic trials, positioning this ITK-ALK as the treatment of choice in first-line treatment. Despite the effectiveness of these new treatments, all patients will virtually experience a relapse. There is no data on second-generation TKI-ALK resistance mechanisms when given as first-line treatment and the best therapeutic strategy for progression is undefined.

The primary endpoint is the Objective Response Rate (ORR) at 6 weeks.
ORR is defined as the proportion of patients achieving an objective response (complete response (CR) or partial response (PR)) according to Response Evaluation Criteria in Solid Tumors (RECIST), v.1.1 (RECIST 1.1), as assessed by the investigators.
Time frame: Time from enrollment until 6 weeks after treatment.
Overall Response Rate (ORR) assessed by an independent review committee (IRC).
Response according to RECIST v.1.1 as assessed by an independent review committee (IRC)
Time frame: Time from enrollment until 6 weeks after treatment
PFS in overall population and in cohort A, B and C.
PFS is defined as the time between the date of inclusion and the first date of documented disease progression according to RECIST 1.1 as assessed by the investigator and the IRC or death from any cause during the study, whichever occurs first.
Time frame: Approximately 8 months after randomization
Disease Control Rate (DCR) in overall population and in cohort A, B and C.
DCR is defined as the percentage of participants with CR, PR, or stable disease (SD) for at least twelve weeks, according to RECIST 1.1.
Time frame: Percentage of participants with CR, PR, or stable disease (SD) for at least twelve weeks (according to RECIST 1.1)
Duration of Response (DOR) in overall population and in cohort A, B and C.
DOR is defined as the time from the first occurrence of an objective response (CR or PR), based on RECIST 1.1 to first documented disease progression or death assessed by an IRC.
Time frame: Approximately 1 year
Overall Survival .
OS is defined as the time from the first lorlatinib dose and death from any cause during the study. OS will be assessed at 6 months, at 12 months and at 18 months.
Time frame: Approximately 1 year
Time to Tumor Response (TTR).
TTR is defined as the time from the first lorlatinib dose and the first occurrence of an objective response (CR or PR) based on RECIST 1.1 and assessed by an IRC.
Time frame: Approximately 1 year
Central Nervous System (CNS) ORR.
CNS ORR is defined as the proportion of patients achieving an objective response (complete response (CR) or partial response (PR)) of the baseline measurable and non-measurable CNS disease according to RECIST 1.1 and Revised Assessment in Neuro Oncology (RANO) criteria, as assessed by an IRC.
Time frame: Approximately 1 year
CNS PFS.
CNS PFS is defined as the proportion of patients achieving an objective response (complete response (CR) or partial response (PR)) of the baseline measurable and non-measurable CNS disease according to RECIST 1.1 and Revised Assessment in Neuro Oncology (RANO) criteria, as assessed by an IRC
Time frame: Approximately 1 year
CNS DOR.
CNS DOR is defined as the time from the first occurrence of an objective response (CR or PR) of the baseline measurable and non-measurable CNS disease for at least twelve weeks, according to RECIST 1.1. and Revised Assessment in Neuro Oncology (RANO) criteria, as assessed by an IRC.
Time frame: Approximately 1 year
CNS TTR.
CNS TTR is defined as the time from the first lorlatinib dose and the first occurrence of an objective response (CR or PR) of the baseline measurable and non-measurable CNS disease, according to RECIST 1.1. and Revised Assessment in Neuro Oncology (RANO) criteria, as assessed by an IRC.
Time frame: Approximately 1 year
Best ORR and PFS depending on prior brigatinib or alectinib treatment
Time frame: Approximately 2 year
