NCT00120471

Brief Summary

To prevent mother-to-child transmission (MTCT) of HIV in resource-limited countries, a simple yet effective treatment plan is needed. Tenofovir disoproxil fumarate (TDF) is an anti-HIV drug approved for use in the United States for the treatment of HIV infected adults. The purpose of this study is to determine the safety, tolerability, and blood levels of TDF in HIV infected pregnant women and their babies. The study will be conducted at sites in Malawi and Brazil.

Outcome Measures

Primary Outcomes (2)

  • Frequency of adverse events with a severity of Grade 3 or higher attributable to receipt of TDF

    Throughout study

  • Maintenance of infant serum concentrations of TDF greater than 50 ng/ml

    Through Week 1

Secondary Outcomes (4)

  • Maternal HIV-1 RNA levels

    At study entry, Days 5 to 7, and Week 6

  • Viral resistance to TDF in all HIV-1 infected infants, all of the corresponding mothers (transmitters), and a subset of mothers whose infants are not infected (nontransmitters). Analysis of TDF in mothers may include testing of breastmilk samples.

    Throughout study

  • HIV infection in infants

    Throughout study

  • TDF concentration in amniotic fluid and breast milk

    Through Week 1

Study Arms (4)

1

EXPERIMENTAL

Pregnant participants will receive a single dose of TDF during active labor. These participants will be hospitalized at the delivery facility through Day 3 postpartum.

Drug: Tenofovir disoproxil fumarate

2

EXPERIMENTAL

Pregnant participants will not receive TDF. Participants will be hospitalized at the delivery facility through Day 7 postpartum. Their infants will receive TDF at birth and on Days 3 and 5 after birth.

Drug: Tenofovir disoproxil fumarate

3

EXPERIMENTAL

Pregnant participants will be hospitalized at the delivery facility through Day 7 postpartum. They will receive TDF during active labor and their infants will receive TDF at birth and on Days 3 and 5 after birth.

Drug: Tenofovir disoproxil fumarate

4

EXPERIMENTAL

Pregnant participants will be hospitalized at the delivery facility through Day 7 postpartum. Mothers will receive TDF during active labor and their infants will receive TDF at birth and daily for 7 days after birth.

Drug: Tenofovir disoproxil fumarate

Interventions

  • Birth weight of less than 2 kg (4.4 lbs)
  • Severe congenital malformation or other medical condition that may affect survival and, in the opinion of the clinician, participation in this study
  • Grade 2 or higher serum creatinine level or any other Grade 3 or higher toxicity
  • Part of a multiple birth (twins, etc.)
