• Healthy on the basis of clinical laboratory tests performed at screening and at admission to the study site on Day -1
• All female participants (regardless of childbearing potential), must have a negative serum beta-human chorionic gonadotropin (beta-hCG) pregnancy test at screening and a negative urine pregnancy test on Day -1
• A woman must be a) Not of childbearing potential; b) Of childbearing potential and practicing a highly effective method of contraception (failure rate of less than (<) 1 percent (%) per year when used consistently and correctly) and agrees to remain on a highly effective method while receiving study intervention and until 3 months after the study treatment administration
• Must sign an informed consent form (ICF) indicating that the participant understands the purpose of, and procedures required for, the study and is willing to participate in the study

Exclusion Criteria:

• Clinically significant abnormal values for hematology, clinical chemistry, or urinalysis at screening or at admission to the study site (Day -1) as determined by the investigator.
