- •9.All male participants who have not had a vasectomy must use effective contraception from Day -1 to 90 days after their last dose of study drug. Effective contraception is defined as a condom and spermicide for the male, or condom and at least one of the following for a female partner:
- •Intrauterine device
- •Oral, injectable, implantable, transdermal, or intravaginal hormonal contraceptive
- •Be of non-childbearing potential
- •10.Male subjects must agree to refrain from sperm donation from the date of Screening until 90 days after their last dose of study drug
