VOICE involves 5,029 women from Uganda, South Africa and Zimbabwe. VOICE is testing not only daily use of an ARV tablet Truvada or tenofovir, but also a vaginal microbicide containing tenofovir in gel form. VOICE is the only trial evaluating both a tablet and a gel in the same study. This design is important for determining how each product works compared to its control (placebo gel or placebo tablet) and which approach women may prefer.
VOICE began in September 2009, completed enrollment in June 2011 and remains on target to complete follow-up in June 2012. By that time, all women will have used their study product for at least one year, some for nearly three years. Women will then be followed for an additional two months. Results are anticipated to be available in early 2013.
Leading the VOICE study are Zvavahera Mike Chirenje, M.D., of the University of Zimbabwe in Harare, and Jeanne Marrazzo, M.D., M.P.H., from the University of Washington in Seattle, U.S.
VOICE is the flagship study of the Microbicide Trials Network (MTN), an HIV/AIDS clinical trials network funded by NIAID with co-funding from the Eunice Kennedy Shriver Institute for Child Health and Human Development and the National Institute of Mental Health, all components of the NIH. MTN principal investigator is Sharon Hillier, Ph.D., and co-principal investigator is Ian McGowan, M.D., Ph.D.
Women make up half of the more than 33 million people living with HIV/AIDS worldwide. In sub-Saharan Africa, six out of 10 new HIV infections in adults occur in women. In several southern African countries, young women aged 15 to 24 are at least three times more likely than their male peer
