Botswana Study of UC-781 Vaginal Microbicide
Phase I Trial of the Safety, Toxicity, and Acceptability of the Microbicide UC-781 When Topically Applied by HIV-uninfected Women and Men in Botswana

Men will be instructed to apply gel topically for 14 consecutive nights, before bed, allow to dry overnight, and wash it off in the morning. Additionally instructed never to use gel during sex but always to use condoms. Volunteers will be seen weekly for evaluation of symptoms, laboratory toxicities, genital exam findings (with colposcopy for women, and plasma drug levels. Acceptability will be assessed in focus groups in the month after completing gel use.
