In this study, you will take the investigational drug by mouth once daily for up to one year. No other form of contraception (condoms, pills, patches, or rings) is allowed during your participation in the study. You’ll also complete an eDiary questionnaire daily and take a home pregnancy test every 28 days. The study site staff will provide training on completing the eDiary correctly. They will also explain how to take the study medication and the home pregnancy test. This study requires two years of your participation.
