• Female participants must be non-pregnant and non-lactating and fulfill at least one of the following:

• Be surgically sterile for a minimum of six months (achieved through hysterectomy, oophorectomy, or bilateral salpingectomy; note that tubal ligation is not considered a method of permanent sterilization).

• Acceptable effective methods of contraception include using a male condom in conjunction with non-hormonal contraceptives, such as a non-hormonal intrauterine device; or a double-barrier method (e.g., male condom with diaphragm and spermicide used simultaneously, male condom with cervical cap and spermicide used simultaneously). Abstinence as a method of contraception is acceptable if it is in line with the preferred and usual lifestyle of the study participant.
