Brief summary

The purpose of this study is to characterize the effect of repeat-dose administration of brigatinib 180 milligram (mg) once daily (QD) on the single-dose pharmacokinetics (PK) of midazolam.

Detailed description

The study will enroll approximately 20 participants to achieve approximately 15 PK-evaluable participants for assessment. This study will consist of 2 parts: Part A of the study will evaluate the effect of repeat-dose administration of brigatinib on the single-dose PK of midazolam. Part B of the study is exploratory and will allow participants to continue brigatinib until disease progression (PD). All participants will receive study drug via the oral route. Participants will be assigned to: Midazolam 3 mg + Brigatinib 90 mg. The overall time to participate in this study is 26 months. Participants will have a 28-day PK cycle in Part A and a maximum of 23 cycles in Part B, and a 30-day follow-up period after end of treatment.

1. Locally advanced or metastatic solid tumors who meet 1 of the following 4 criteria: * With locally advanced or metastatic ALK-positive NSCLC who have progressed on or are intolerant to treatment with at least 1 other ALK inhibitor. * With ALK-positive nonlung solid tumors that are locally advanced or metastatic and for whom no standard, nonexperimental therapy is available. * With locally advanced or metastatic ROS1-positive NSCLC who have progressed on crizotinib therapy or are intolerant to crizotinib, or * With ROS1-positive nonlung solid tumors that are locally advanced or metastatic and for whom no standard, nonexperimental therapy is available. 2. Eastern cooperative Oncology Group (ECOG) performance status of 0 or 1. 3. Have at least 1 target lesion per response evaluation criteria in solid tumors (RECIST) version 1.1. 4. Have recovered from toxicities related to prior anticancer therapy to National Cancer Institute common terminology criteria for adverse events (NCI CTCAE) version 4.03 Grade less than or equal to (\<=) 1. 5. Suitable venous access for study-required blood sampling (that is, including PK and laboratory safety tests).

Exclusion criteria

1. Systemic treatment with strong or moderate cytochrome P450 3A (CYP3A) inhibitors or inducers within 14 days before enrollment. 2. Prior therapy with brigatinib. 3. Received prior ALK-inhibitor therapy within 7 days before the first dose of study drug. 4. Treatment with any investigational systemic anticancer agents within 14 days or 5 half-lives, whichever is longer, before the first dose of study drug. 5.

Participant flow

Recruitment details

Participants took part in the study at 10 investigative sites in the Netherlands, Italy, and Spain from 26 June 2019 to 29 April 2021.

Pre-assignment details

Participants with anaplastic lymphoma kinase-positive (ALK-positive) or ROS1-positive solid tumors, including non-small-cell lung cancer (NSCLC) were enrolled in this two-part study to receive midazolam with and without repeated doses of brigatinib in Part A, and further continued treatment with brigatinib at their highest tolerated dose (up to 180 milligram \[mg\]) in Part B. As planned, combined safety data for Parts A and B were collected and reported.

Outcome results

Primary

Part A, AUC∞: Area Under the Plasma Concentration-time Curve From Time 0 to Infinity for Midazolam

The statistical analysis was calculated via a mixed-effects analysis of variance (ANOVA) fitting terms for treatment (midazolam with or without brigatinib coadministration).

Time frame: Cycle 1, Days 1 (Midazolam alone) and 21 (Midazolam + Brigatinib): pre-dose and at multiple timepoints (up to 24 hours) post-dose (Cycle length is 28 days)

Population: PK-evaluable population: participants who received protocol-specified regimen during Part A (including brigatinib 180 mg) without dose reductions/interruptions, did not receive any excluded concomitant medications through completion of PK sampling and had sufficient midazolam concentration-time data to estimate PK parameters by noncompartmental analysis methods. As planned, OM was assessed for Part A only. Overall number of participants analyzed were participants who were evaluable for this OM.
