Male or female (according to their reproductive organs and functions assigned by chromosomal complement at birth). 11. A female using oral contraceptivesmust use an additional barrier contraceptive method (details in Appendix 5: Contraceptive Guidance). A female participant must be either of the following (as defined in Appendix 5: Contraceptive Guidance) 1. Not of childbearing potential: premenarchal; postmenopausal (\>45 years of age with amenorrhea for at least 12 months); permanently sterilized (eg, bilateral tubal occlusion, hysterectomy, bilateral salpingectomy, bilateral oophorectomy); or otherwise, be incapable of pregnancy. 2. Of childbearing potential and practicing at least 1 highly effective method(s) of birth control consistent with local regulations regarding the use of birth control methods for participants participating in clinical studies, as described below: * Practicing true abstinence (when this is in line with the preferred and usual lifestyle of the participant), which is defined as refraining from heterosexual intercourse during the entire period of the study, and for 7 months after the last dose of the study treatment. Periodic abstinence (calendar, symptothermal, post-ovulation methods) is not considered an acceptable contraceptive method. * Have a sole partner who is vasectomized. * Practicing 2 methods of contraception, including one highly effective method (ie, established use of oral, intravaginal, transdermal, injected or implanted hormonal methods of contraception; placement of an intrauterine device \[IUD\] or intrauterine system \[IUS\], tubal ligation procedures as consistent with local regulations), AND, a second method, (eg, condom with spermicidal foam/gel/film/cream/suppository or occlusive cap \[diaphragm or cervical/vault caps\] with spermicidal foam/gel/film/cream/suppository). * Participants must agree to continue contraception throughout the study and continuing through 7 months after the last dose of the study treatment. Note: If the childbearing potential changes after start of the study (eg, woman who is not heterosexually active becomes active, premenarchal woman experiences menarche) the woman must begin a method of birth control, including 1 highly effective method, as described above. 12. A female participant of childbearing potential must have a negative serum (b-human chorionic gonadotropin \[b-hCG\]) at screening (within 72 hours of the first dose of study treatment administration) and must agree to further serum or urine pregnancy tests during the study prior to Day 1 of each cycle and at End of Study. 13. A female must agree not to donate eggs (ova, oocytes) or freeze for future use for the purposes of assisted reproduction during the study and for a period of 7 months after the last dose of the study treatment. Female participants should consider preservation of eggs prior to study treatment as anti-cancer treatments may impair fertility. 14. A male participant must wear a condom when engaging in any activity that allows for passage of ejaculate to another person during the study and for 6 months after the last dose of the study treatment. 15. If the male participant's partner is a female of childbearing potential, the male participant must use condom with or without spermicide and the female partner of the male participant must also be practicing a highly effective method of contraception (see Appendix 5: Contraceptive Guidance). A male participant who is vasectomized must still use a condom (with or without spermicide), but the partner is not required to use contraception. 16. A male participant must agree not to donate sperm for the purposes of reproduction during the study and for 6 months after the last dose of the study treatment (whichever comes last). Male participants should consider preservation of sperm prior to study treatment as anti-cancer treatments may impair fertility. 17. A male participant must agree not to plan to father a child while enrolled in this study and for 7 months after the last dose of the study treatment (whichever comes last). Exclusion Criteria: 1.
