Feasibility of Vaginal Progesterone to Reduce HIV-Associated Preterm Birth

More than 1.5 million HIV-infected women become pregnant each year. Approximately half have access to antiretroviral therapy (ART), but all are at increased risk of preterm birth (PTB). Vaginal progesterone (VP) is a promising and cost-effective intervention to prevent PTB that should be studied in this high-risk population. This pilot study will provide critical insight into the feasibility of a phase III trial by determining whether women are willing to participate, to adhere to study drug, and to complete follow-up.
