Eligibility Criteria

18 Years - 49 Years (Adult)All SexesAccepts Healthy Volunteers

Inclusion Criteria:

  • Subject is 18 to 49 years of age, inclusive, on the day of screening
  • Subject has an understanding of the study and its procedures, agrees to its provisions, and gives written informed consent prior to study entry

For the purposes of this study at least one of the following types of US Food and Drug Administration (FDA) approved birth control measures shall be applied through completion of the Day 181 study visit:

    • Hormonal types of birth control (such as implants or birth control pills) or an intrauterine device
    • A barrier type of birth control measure (i.e. condoms, diaphragms, cervical caps, etc.)

Exclusion Criteria:
