Note: Men with a pregnant or breastfeeding partner must agree to remain abstinent from penile-vaginal intercourse or use a condom during each episode of penile-vaginal penetration. 3. Females of childbearing potential (i.e., not postmenopausal or surgically sterile) must agree to one of the following from start of Screening through 90 days after the last study drug administration: a. use two effective methods of birth control, including hormonal prescription oral contraceptives, contraceptive injections, contraceptive patch, contraceptive ring, intrauterine device, barrier method (e.g., condoms, diaphragm, or cervical cap) or spermicidal foam, cream or gel, or b. practice complete abstinence, or c. monogamous relationship with a male partner of confirmed sterility. 4. Body weight equal to or greater than 50 kg and body mass index (BMI) between 18 and 35 kg/m2, inclusive at Screening 5. Participant is free from clinically significant illness or disease as determined by medical and surgical history, physical examination, 12-lead ECG and clinical laboratory assessments conducted at Screening and Day -1 as agreed to by the Investigator and Medical Monitor. 6. No current use of any prescription medication, over-the-counter medication, or herbal supplements/products during Screening or throughout study, unless approved by both the Investigator and the Sponsor 7. Able to understand and sign the written Informed Consent Form (ICF) 8.
