Inclusion and exclusion criteria

Key Inclusion Criteria:

• Be a nonsmoker. The use of nicotine or nicotine-containing products must be discontinued 90 days prior to the first dose of study drug.
• Have a calculated body mass index (BMI) of greater than or equal to (≥) 19.0 and less than or equal to (≤) 30.0 kilogram per meter square (kg/m^2) at screening.
• Have a creatinine clearance (CLcr) ≥ 90 milliliters per minute (mL/min) (using the Cockcroft-Gault method) based on serum creatinine and actual body weight as measured at screening and upon admission.
• Female participants of childbearing potential must have a negative serum pregnancy test at screening and a negative urine pregnancy test at clinic admission.
• Male participants must be surgically sterile.
• Male participants and female participants of childbearing potential who engage in heterosexual intercourse must agree to use protocol-specified method(s) of contraception.
• Screening laboratory evaluations and 12-lead electrocardiogram (ECG) evaluations must be without clinically significant abnormalities as assessed by the investigator.
• Have liver biometric tests such as alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase, and total bilirubin below the upper limit of normal at screening.
• Must be willing and able to comply with all study requirements.
• Must, in the opinion of the investigator, be in good health based upon medical history and physical examination, including vital signs.
• Participants must not have donated blood within 56 days of study entry or plasma within 7 days of study entry and must refrain from blood donation from clinic admission, throughout the study period, and continuing for at least 30 days following the last dose of study drug.

Key Exclusion Criteria:

• Positive serum pregnancy test (Female participants).
• Lactating female.
• Have received any investigational drug/device within 30 days prior to study dosing (or within 5 half-lives of the drug, whichever is longer).
• Have current alcohol or substance abuse judged by the investigator to potentially interfere with participant compliance or participant safety, or a positive drug or alcohol test at screening or admission.
• Have a positive test result for human immunodeficiency virus type 1 (HIV-1) antibody, hepatitis B virus (HBV) surface antigen (HBsAg), or hepatitis C virus (HCV) antibody at screening.
• Have positive Coronavirus Disease 2019 (COVID-19) Real-Time Reverse.
• Transcriptase-Polymerase Chain Reaction (RT-PCR) testing on screening and admission.
• Have poor venous access that limits phlebotomy.

Note: Other protocol defined Inclusion/Exclusion criteria may apply.
