Detailed Description

This is a Phase 3, multi-center, randomized, placebo-controlled trial to assess the effectiveness of CS gel in preventing male-to-female vaginal transmission of HIV among HIV sero-negative women at high risk for HIV infection. Eligible participants who are HIV negative, at risk for becoming infected, and are willing to use a vaginal microbicide each time they have intercourse throughout 12 months of study participation will be recruited in Port Harcourt and Lagos, Nigeria.
