Participant Flow

A total of 4 participants were screened. Among them, 1 participant was enrolled and treated in Group B (mild impairment), 1 participant was eligible for Group A (normal) but not enrolled as Group A was not open for enrolment at that time, and 2 participants were screen failed.

Measure
Group A1 Normal Hepatic Function
Continued daily administration of lorlatinib 100 mg in patients with normal hepatic function until disease progression, patient refusal, or unacceptable toxicity occurrence
Group A2 Normal Hepatic Function
Continued daily administration of lorlatinib in patients with normal hepatic function at the dose level same as Group C for the first 22 days and 100 mg once a day (QD) afterwards.

SECONDARY outcome

Timeframe: From Screening (within 28 days prior to Cycle 1 Day 1) through and including at least 28 days after after the last lorlatinib dose. The duration is approximately 42 days.

Population: The analysis population included all enrolled participants who received at least 1 dose of lorlatinib.

An Adverse event (AE) was any untoward medical occurrence in a participant. A serious AE was any untoward medical occurrence at any dose that resulted in death; was life-threatening; required hospitalization or prolongation of existing hospitalization; resulted in persistent or significant disability/incapacity; resulted in congenital anomaly/birth defect or that was considered to be an important medical event. AEs were graded by the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE) version 4.03. The grades were defined as follows: Grade 0: no change from normal or reference range; Grade 1: mild AE; Grade 2: moderate AE; Grade 3: severe AE; Grade 4: life-threatening consequences, urgent intervention indicated; Grade 5: death related to AE. The focus of AE summaries was on treatment-emergent AE (TEAE). An AE was considered TEAE if the event occurred during the on-treatment period.
