   3. Stable hormonal contraception for at least 1 month prior to study through study completion; or
   4. Surgical sterilization (vasectomy) of male partner at least 6 months prior to study.
7. To be considered of non-childbearing potential, females should be surgically sterilized (bilateral tubal ligation, hysterectomy, or bilateral oophorectomy at least 2 months prior to study) or be post-menopausal and at least 3 years since last menses.
8. Male participants must use condoms during the study and through study completion.
