Washington: A vaginal ring releasing an anti-HIV drug can prevent the transmission of SHIV in macaques, a new study has found.This study by Population Council provides the first efficacy data on the delivery of a microbicide from a vaginal ring, and indicates strong potential for the success of such rings in women.Microbicides are compounds that can be applied inside the vagina or rectum to protect against sexually transmitted infections (STIs), including HIV.“This proof-of-concept study confirms that the investment in vaginal rings as a delivery system for HIV prevention is paying off,” Naomi Rutenberg, vice president and director of the Population Council``s HIV and AIDS Program, said.“Our findings show that rings can deliver an anti-HIV drug to prevent infection,” she said.In this study, Council scientists examined whether vaginal rings containing MIV-150, a proprietary non-nucleoside reverse transcriptase inhibitor, could prevent the transmission of immunodeficiency virus.
