PITTSBURGH, 9 March 2021 - If approved, the monthly dapivirine vaginal ring would be the first biomedical HIV prevention method designed specifically for cisgender women, as well as the first long-acting method. Looking to the future, researchers from the National Institutes of Health-funded Microbicide Trials Network are hopeful that a vaginal ring that could be used for longer than a month at a time might also be made available someday.
Indeed, a 90-day dapivirine ring has passed its first test, with results of a Phase I clinical trial reported today at a virtual meeting of the Conference on Retroviruses and Opportunistic Infections (CROI) supporting its further development.
