Of childbearing potential and practicing (during the study and for 6 months after receiving the last dose of study agent for women and 3 months after receiving the last dose of study agent for men)) a highly effective method of birth control consistent with local regulations regarding the use of birth control methods for subjects participating in clinical studies: e.g., established use of oral, injected or implanted hormonal methods of contraception; placement of an intrauterine device (IUD) or intrauterine system (IUS); barrier methods; true abstinence (when this is in line with the preferred and usual lifestyle of the subject).
    3. Note: If the childbearing potential changes after start of the study (eg, woman who is not heterosexually active becomes active) a woman must begin a highly effective method of birth control, as described above.

13. A woman of childbearing potential must have a negative serum (β-human chorionic gonadotropin [β-hCG]) or urine pregnancy test at screening.

14. During the study and for 6 months after receiving the last dose of study agent, a woman must agree not to donate eggs (ova, oocytes) for the purposes of assisted reproduction.

15. A man who is sexually active with a woman of childbearing potential and has not had a vasectomy must agree to use a barrier method of birth control e.g., either condom with spermicidal foam/gel/film/cream/suppository or partner with occlusive cap (diaphragm or cervical/vault caps) with spermicidal foam/gel/film/cream/suppository, and all men must also not donate sperm during the study and for 3 months after receiving the last dose of study drug.

16. Institutional Review Board (IRB)/Independent Ethics Committee (IEC) approved written informed consent and privacy language as per HIPAA must be obtained from the subject or legally authorized representative (if applicable) prior to any study- related procedures
