MTN-004 was a double-blind, placebo-controlled study investigating the safety, tolerability, and systemic absorption of 3% VivaGel® when administered vaginally twice daily for 14 consecutive days in healthy, sexually active, HIV-negative young women. This study was a collaborative effort between the MTN and the Adolescent Medicine Trials Network for HIV/AIDS Interventions (ATN) funded by the Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD). Participants were to be randomized to either 3% w/w VivaGel® or VivaGel® placebo in a 1:1 ratio.
Enrollment into this study began in July 2007 and was paused in October 2007 for a review of adverse event data. An interim blinded review of laboratory and clinical data on the seven enrolled women took place and confirmed that the study could continue. The protocol was revised and a third treatment arm was added to the study, a universal hydroxyethylcellulose (HEC) placebo gel arm, so that newly enrolled women would be assigned to receive either VivaGel®, VivaGel® placebo, or HEC placebo gel.. Thus, the study provides a comparison of the safety of VivaGel®, VivaGel® placebo and the HEC placebo gel in sexually active young women. Results were first presented at the Microbicides 2010 conference. The primary manuscript was published in AIDS on May 15, 2011.
