WOCBP, not surgically sterilized (hysterectomy, bilateral salpingectomy, and bilateral oophorectomy), and not post-menopausal for at least 24 consecutive months, i.e., have had menses within the preceding 24 months, must have a negative serum pregnancy test performed within 72 hours prior to initiation of study drug 16. WOCBP and male participants of reproductive potential with WOCBP partners must agree to consistently use a highly effective method of contraception and a barrier method (condom, diaphragm or cervical cap) for the duration and for 30 days afterwards. Highly effective methods include the following: Highly effective methods include: * Contraceptive subdermal implant * Intrauterine device or intrauterine system * Combined estrogen and progestogen oral contraceptive * Injectable progestogen * Contraceptive vaginal ring * Percutaneous contraceptive patches * True sexual abstinence (only if it is the participant's consistent lifestyle choice and not just trial-related). * Sterilization of male partner with documentation of azoospermia prior to the participant's entry into the study, and this individual is the sole partner for the participant. The documentation of partner sterility can come from the site personnel's review of medical records, medical examination and/or semen analysis, or medical history interview provided by the participant or the partner. Self-reported documentation of reproductive potential should be entered in the source documents. Barrier method may include: * Male or female condoms with or without a cream or gel that kills sperm * Diaphragm or cervical cap with a cream or gel that kills sperm * Sponge 17.
