Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

1. Able to verbalize understanding of the consent form, able to provide written informed consent, and verbalize willingness to complete study procedures, be able to comply with protocol requirements, rules and regulations of study site, and be likely to complete all the study interventions.
2. Female subjects of child-bearing potential who are sexually active with males must use, with their partner, a condom plus an approved method of effective contraception from the time of screening until 30 days after the last dose of Investigational Medicinal Product (IMP). The impact of IMP on the efficacy of hormonal contraceptives is unknown. Male subjects who are sexually active with female partners of child-bearing potential must use, with their partner, a condom plus an approved method of effective contraception from the time of screening until 90 days after the last dose of IMP and agree to not donate sperm over this time period. Effective methods of contraception are:

1. Combined (estrogen and progestogen-containing) hormonal contraception associated with inhibition of ovulation: oral, intravaginal, or transdermal
2. Progestogen-only hormonal contraception: oral, injectable/implantable, or intrauterine hormone-releasing system (IUD)
