Birth Control Ring Study

CCN019 Vaginal Ring Study Image

This study will look at two different formulations of the ring containing levonorgestrel (a type of progestin used in many currently approved birth control methods) and dapivirine (an investigational medication being developed to prevent HIV). The study will investigate how the medications are circulated through the body, the study product’s safety, and how much users like the ring. It will follow 20 participants for approximately 90 days of continuous ring use. There will be 14 clinic visits and up to four follow-up phone contacts throughout six to nine months of participation. Study activities include blood draws, pelvic exams, urine ovulation testing, and a daily user diary. We are enrolling participants who are not at risk for pregnancy or HIV infection.
