MTN-029/IPM 039 was a Phase I, open-label study that was designed to assess the presence of dapivirine in blood, breast milk, and cervicovaginal fluid when delivered via a vaginal ring used continuously for 14 days. The trial also evaluated the safety and tolerability of the dapivirine vaginal ring when used for 14 consecutive days as well as adherence to the dapivirine vaginal ring in lactating women. The study enrolled 16 healthy, HIV-negative women, aged 18 years or older, at least 6 weeks postpartum, who were lactating but not breastfeeding, at two U.S. sites.
The study completed follow-up on March 3, 2017. Primary results were presented at the International AIDS Society (IAS) HIV Pathogenesis, Treatment & Prevention meeting, July 23- 26, 2017, in Paris, France and at the Infectious Diseases Society for Obstetrics and Gynecology (IDSOG) meeting held on Aug 10-12, 2017 in Park City, UT. The primary manuscript was published in Antimicrobial Agents and Chemotherapy on February 26, 2019.
