- Read more about NIH-Funded Clinical Trial to Test PrEP, Dapivirine Ring for Safety in Pregnant Women
The first clinical trial specifically designed to test the safety of the monthly dapivirine vaginal ring in pregnant women has begun in southern and eastern Africa. The National Institutes of Health-funded study also will test the safety of a daily oral antiviral tablet for HIV pre-exposure prophylaxis (PrEP) in pregnant women and will assess how much they accept and use these two HIV prevention tools. The study will complement an ongoing NIH-funded trial of PrEP in adolescents and young women during pregnancy and the first six months after birth. PrEP is available in some countries and is being rolled out in others, while the dapivirine ring is under regulatory review by the European Medicines Agency for potential use in sub-Saharan Africa.
