Topical Metronidazole and Miconazole Co-formulated Vaginal Suppositories for Preventing Vaginal Infections in HIV-seronegative Women

Completed · Phase 2 · Has a placebo group

Conditions studied: Bacterial Vaginosis, Candidiasis, Trichomoniasis

In brief

This research study is about vaginal infections such as bacterial vaginosis, yeast infections, and trichomoniasis. Usually, these infections can be treated with medication, but sometimes they come back after treatment. Researchers want to know if using vaginal suppositories can decrease the risk of vaginal infections. Participants will include 234 women who are sexually active (greater than or equal to 4 episodes of sex with men during the past month), HIV-negative, 18 to 45 years old, with bacterial infection \[vaginosis and/or vulvovaginal candidiasis (VVC) and/or Trichomonas vaginalis\] detected by laboratory testing at a screening visit. Women will receive vaginal suppositories containing drug or inactive ingredients (placebo). Participation in the study will be about 12 months. Study procedures include: urine and blood tests, physical exams, and questionnaires.
