Inclusion criteria

* Body mass index between 18 and 32 kilograms/meter squared (kg/m\^2) inclusive, at the screening visit. * Healthy, as determined by physical examination, vital signs, electrocardiograms (ECGs), and clinical laboratory assessments (including hematology, chemistry, and urinalysis) within the normal range at the screening visit and/or on Day -1. * Cytochrome P450 (CYP) 2C19 normal, rapid, or ultrarapid metabolizer, as determined by genotyping during screening.

Exclusion criteria

* Any significant acute or chronic medical illness. * Current or history of clinically significant cardiac condition, including but not limited to arrhythmia, left ventricular systolic dysfunction, coronary heart disease; current, history, or family history of hypertrophic cardiomyopathy; or evidence of prior myocardial infarction based on ECGs. * CYP2C19 poor (\*2/\*2, \*3/\*3, or \*2/\*3) or intermediate (\*1/\*2, \*1/\*3, \*2/\*17) metabolizer, as determined by genotyping during screening. * Use of CYP2C19 and CYP3A4 inducers or inhibitors within 28 days of study intervention administration.
