Brief Summary

Tenofovir 1% gel is an investigational vaginal microbicide intended to reduce the risk of transmission of HIV. Pregnant women and mothers who have recently given birth often maintain sexual activity, and research has shown that they may be at greater risk of HIV infection during pregnancy. Microbicides may be able to prevent HIV infection during pregnancy, which would also prevent fetal exposure to HIV. This study will test the safety of using tenofovir 1% gel in healthy, pregnant women and healthy, breastfeeding women.

Outcome Measures

Primary Outcomes (5)

  • Safety and tolerability in pregnant women

    Safety and tolerability in pregnant women are assessed by number of specific Grade 2 or greater adverse events in laboratory abnormalities, genital/pelvic signs/symptoms, or pregnancy complications

    Measured at 2 weeks post-delivery

  • Safety and tolerability in infants, defined as no intensive care admission greater than 24 hours and no sepsis

    Measured at 2 weeks post-delivery

  • Safety and tolerability in lactating women, defined as specific Grade 2 or greater adverse events in laboratory abnormalities or genital/pelvic signs/symptoms

    Safety and tolerability in lactating women are assessed by number of specific Grade 2 or greater adverse events in laboratory abnormalities or genital/pelvic signs/symptoms

    Measured at Day 14

  • Safety and tolerability in infants of lactating mothers

    Safety and tolerability in infants of lactating mothers is defined as no inpatient admission (confirmed on review of medical records) with diagnosis of adverse event (AE) judged to be related to study product

    Measured at Day 14

  • Tenofovir levels in maternal blood or breast milk

    Measured at Day 6 or delivery, depending on cohort

Secondary Outcomes (3)

  • Presence of tenofovir in blood among infants of participants in the pregnancy and lactation cohorts

    Measured at Day 6 or delivery, depending on cohort

  • Impact of tenofovir gel exposure on the presence of select organisms associated with neonatal sepsis among participants in the pregnancy cohort, (e.g., Group B β-hemolytic streptococcus, Escherichia coli)

    Measured at Day 6

  • Adherence to daily use of tenofovir 1% gel for 7 days and its acceptability among pregnant and lactating women

    Measured at Day 6

  • Clinically apparent pelvic exam finding of Grade 2 or higher (observed by study staff) at the enrollment visit
  • Use of oral and/or vaginal preparations of antibiotic or antifungal medications at screening or within 7 days of enrollment (Day 0)
  • Any social or medical condition that, in the investigator's opinion, would preclude informed consent, make study participation unsafe, complicate interpretation of study outcome data, or otherwise interfere with achieving the study objectives
