Brief summary: The main aim of this study is to compare the amount of brigatinib in the blood of healthy adults after they have swallowed one dose either as a solution or as a tablet.

Detailed description: The drug being tested in this study is called brigatinib. Brigatinib is being tested to assess its relative bioavailability when administered as an oral solution versus as an immediate-release tablet in healthy participants.

The study will enroll approximately 12 participants. Participants will be randomly assigned to one of the treatment sequences:

* Sequence 1: Treatment A followed by Treatment B
* Sequence 2: Treatment B followed by Treatment A wherein Treatment A is a 90 mg oral solution dose and Treatment B is a 90 mg tablet dose.

There will be a washout period of at least 14 days between brigatinib administration in each study period. The follow-up contact will occur 14 (±2) days post the last dose of study drug.

This single-center trial will be conducted in the United States. The overall study duration is approximately 56 days.

Eligibility criteria: Inclusion Criteria:

1. Continuous nonsmoker who has not used nicotine-containing products for at least 3 months prior to the first dosing and throughout the study.
2. Body mass index (BMI) ≥18.0 and ˂32.0 kilograms per meters squared (kg/m\^2) at screening.
3. Pulse rate between 60 and 100 beats per minute (bpm) and a blood pressure between 90 to 140 millimeters of mercury (mmHg) systolic and 40 to 90 mmHg diastolic at screening and prior to dosing of Period 1.
4. Creatine phosphokinase is ≤1.1x upper limit of normal \[ULN\]; lipase, amylase, alanine aminotransferase (ALT), aspartate aminotransferase (AST), total bilirubin, glucose, and activated partial thromboplastin time (aPTT) are ≤ULN at screening and check-in of Period 1.

Exclusion Criteria:

1. Any history of major surgery.
2. History or presence of hypersensitivity or idiosyncratic reaction to the study drug or related compounds.
3. Unable to refrain from or anticipates the use of any drug, including prescription and nonprescription medications, herbal remedies, or vitamin supplements within 28 days prior to the first dosing and throughout the study.
4. Positive results at screening for Human Immunodeficiency Virus (HIV), Hepatitis B surface Antigen (HBsAg), or Hepatitis C Virus (HCV).
5. Positive coronavirus disease 2019 (COVID-19) results at first check-in.
6. Donation of blood or significant blood loss within 56 days prior to the first dosing.
7. Plasma donation within 7 days prior to the first dosing.
