Inclusion criteria

* Body mass index (BMI) ≥ 18.0 and ≤ 30.0 kilogram per meter square (kg/m2) at Screening. * Medically healthy with no clinically significant medical history, physical examination, laboratory profiles, vital signs or electrocardiograms (ECGs), as deemed by the principal investigator (PI) or designee.

Exclusion criteria

* Positive results for coronavirus infection (COVID-19) at Screening or check-in (Day -1). * History or presence of alcohol or drug abuse within the past 2 years prior to the first dosing. * Positive urine drug or alcohol results at Screening or check in (Day -1). * Smoker who has smoked or used nicotine containing products within the last 3 months prior to the first dose and throughout the study, confirmed by a negative cotinine test at Screening and check-in (Day -1). * History or presence of hypersensitivity or idiosyncratic reaction to the study drugs or related compounds. * Hemoglobin, absolute neutrophil count, or platelet levels outside of the reference range at Screening. * History of prolonged QT syndrome or a corrected QT (QTc) interval. * Positive results at Screening for human immunodeficiency virus (HIV), hepatitis B surface antigen (HBsAg) or hepatitis C virus (HCV). * Participation in another clinical study within 5 half-lives or 30 days, whichever is longer, of the Baseline visit.
