Inclusion criteria

* Body mass index between 18 and 32 kg/m\^2, inclusive, at the screening visit. * Healthy, as determined by physical examination, vital signs, 12-lead ECGs, and clinical laboratory assessments (including hematology, chemistry, and urinalysis) within the normal range at the screening visit and/or on Day -1. Participants with values outside of the normal range may be included if the values are not considered, by the investigator, to be clinically significant unless such values are explicitly excluded. * Cytochrome P450 (CYP2C19) normal (\*1/\*1), rapid (\*1/\*17), or ultra-rapid (\*17/\*17) metabolizer, as determined by genotyping during screening.

Exclusion criteria

* Current or history of clinically significant cardiac condition, including but not limited to arrhythmia, LV systolic dysfunction, coronary heart disease; current, history, or family history of HCM; or evidence of prior myocardial infarction based on ECGs. * Current or recent (within 3 months of study intervention administration) gastrointestinal disease including, but not limited to, bowel obstruction or perforation, gastrointestinal ulcers, esophageal varices, Crohn's disease, diverticulitis, irritable bowel syndrome, ileus, a gastrointestinal tract that is not anatomically intact, dyspepsia, constipation, diarrhea, or vomiting. * Any gastrointestinal surgery (other than appendectomy) that, in the opinion of the investigator, could impact the absorption of study intervention.
