6. Participants must be generally healthy, free of lifetime malignant tumors, and without clinically significant abnormalities as assessed by the Investigator based on the review of medical and surgical history, physical examination, vital signs, 12-lead ECG, and laboratory evaluations conducted at screening and Check-in, as applicable. A single repeat measurement/test may be performed to confirm vital signs, 12-lead ECG, and clinical laboratory tests abnormalities (i.e.,to confirm that a participant is eligible).

Male participants, if not surgically sterilized, must agree to use adequate contraception and not donate sperm from first Check-in (Day -1) to the clinical site until 90 days after the last administration of study product. Adequate contraception for the male participant (and his female partner, if she is of childbearing potential) is defined as using hormonal contraceptives or an intrauterine device combined with at least 1 of the following forms of contraception: a diaphragm, a cervical cap, or a condom. Total abstinence from heterosexual intercourse, in accordance with the lifestyle of the subject, is also acceptable.

    * Exclusive partner who is clinically sterile (i.e., documented infertility or surgical sterilization; see below for additional information on sterility) or has been vasectomized for at least 6 months (inclusive) prior to first Check-in
    * Note: Sexual abstinence, defined as refraining from intercourse, is allowed when this is in line with the preferred and usual lifestyle of the participant. Female participants of childbearing potential who are not currently engaging in heterosexual intercourse must agree to use one of the above methods of birth control through completion of study, in the event that they have heterosexual intercourse during the course of the study.

    * Hysteroscopic sterilization (including Essure or similar nonsurgical sterilization procedures)
    * Bilateral tubal ligation or bilateral salpingectomy
    * Hysterectomy
    * Bilateral oophorectomy
