NCT00540605

Brief Summary

A new approach to HIV prevention currently being studied includes the use of topical microbicides, substances that kill microbes. The purpose of this study is to determine the levels of tenofovir, a microbicide in gel form, in HIV uninfected pregnant women who are expecting to deliver by cesarean.

Eligibility Criteria

Age18 Years - 45 Years
Sexfemale
Healthy VolunteersYes
Age GroupsAdult (18-64)

You may qualify if:

  • General good health
  • HIV uninfected
  • Hepatitis B surface antigen negative at screening and enrollment
  • Viable, single pregnancy delivered by cesarean section planned between 37 0/7 to 41 6/7 weeks of pregnancy
  • Normal Pap smear in the 12 months prior to study entry
  • Willing to abstain from vaginal, anal, and receptive oral sex for at least 2 weeks after gel administration
  • Willing to abstain from intravaginal products and practices (including douching) during study participation

You may not qualify if:

  • Maternal or fetal condition that requires urgent cesarean section
  • Documented rupture of the amniotic membranes
  • Known disease in the mother that has a predictable negative effect on placental function
  • Known placental/fetal abnormalities that could affect placental transfer. More information on this criterion can be found in the protocol.
  • Previously demonstrated hypersensitivity to any components of tenofovir 1% gel
  • Certain abnormal laboratory values
  • Use of vaginal medications within 48 hours of study entry
  • Untreated sexually transmitted infection (STI) or exposure to partner's STI, including chlamydia, gonorrhea, trichomoniasis, and nongonococcal urethritis
  • Symptomatic vaginitis, including bacterial vaginosis and vulvovaginal candidiasis. Participants with asymptomatic signs of bacterial vaginosis and/or yeast not excluded.
  • Participation in any other investigational drug or device trial within 30 days of study entry
  • Any social or medical condition that, in the opinion of the investigator, would interfere with the study
