  Purpose

The purpose of this study is to evaluate the pharmacokinetics (PKs) of antiretroviral (ARV) and tuberculosis (TB) medications in pregnant women and their infants. (Pharmacokinetics are the various interactions between a drug and the body.) This study will also evaluate the PKs of certain ARVs in postpartum women before and after starting hormonal contraceptives. The PKs of these drugs will be evaluated by measuring the amount of medicine present in blood and/or vaginal secretions.

Detailed Description:

Pregnant women experience unique physiological changes that may result in clinically significant alterations in drug PKs. Unfortunately, there have been few clinical trials to study the PKs of ARV, TB, and hormonal contraceptive drugs in pregnant women. The development of appropriate dosing regimens for the HIV-infected pregnant woman is critical to the health of both mother and fetus. Overdosing may lead to maternal adverse events and increased risk of fetal toxicity, while underdosing may lead to inadequate virologic control, increased risk of developing drug resistance mutations, and a higher rate of perinatal HIV transmission. This study will evaluate dosing regimens that are most effective in preventing perinatal HIV transmission and in maintaining the health of both mother and fetus; evaluate the PKs of ARVs used during pregnancy; evaluate TB drugs used during pregnancy, both in women who are HIV-positive and also taking ARVs and in women who are HIV-negative and not taking ARVs; and evaluate the PKs of hormonal contraceptive medications taken along with ARVs.

There will be four main groups of study arms: HIV-infected pregnant women taking ARVs without TB treatment, HIV-infected pregnant women taking ARVs with TB treatment, HIV-uninfected pregnant women taking no ARVs with TB treatment, and HIV-infected pregnant women taking ARVs with postpartum hormonal contraceptives. Participants will not receive medications through this study—they will continue on ARV, TB, and/or contraceptive medications prescribed by their health care providers.

Women who are 20 0/7 weeks to 34 6/7 weeks pregnant will be enrolled in this study and will remain in the study for 24 weeks after delivery. Postpartum women will be enrolled at 2 to 12 weeks after delivery and followed until 6 to 7 weeks after starting contraceptives. Infants will be followed until 24 weeks of life. At all study visits, women will undergo a medical history, a physical exam, and blood collection. At some visits, women in some arms will undergo a vaginal swab. Blood collection from the mother and the detached umbilical cord will occur during delivery. Intensive PK sampling will be performed at study visits during the second and third trimester of pregnancy and between 2 and 3 weeks, 2 and 8 weeks, or 6 and 12 weeks postpartum, with the first sampling occurring within 72 hours of enrollment. The timing of antepartum and postpartum PK samplings will vary by study arm. Additional study visits may occur depending on the ARV drug regimen prescribed.

  Eligibility

Genders Eligible for Study:   Female
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  • Participant must belong to one of the following 4 groups:

    1. HIV-infected pregnant woman at least 20 weeks gestation and NOT on TB treatment, receiving one or more of the ARV drugs/drug combinations specified in the protocol
    2. HIV-infected pregnant woman at least 20 weeks gestation receiving one of the ARV drugs/drug combinations specified in the protocol and rifampicin-containing TB treatment with at least one of the TB drugs, specified in the protocol, at study entry
    3. HIV-uninfected pregnant woman at least 20 weeks gestation receiving at least two TB drugs, specified in the protocol, at study entry
    4. HIV-infected woman 2 to 12 weeks (14 to 84 days) post-delivery receiving one of the ARV drug combinations listed in the protocol AND starting postpartum contraceptives as listed in the protocol
  • The woman must be stable on the ARV drug/drug combination and/or TB drug combination for at least 2 weeks prior to PK sampling
  • HIV-infected pregnant women must be planning to continue on current ARV regimen until postpartum PK sampling is completed
  • HIV-infected pregnant women must be enrolled in the P1025 study if available at the potential participant's site
  • For HIV-infected women who are not co-enrolled in the P1025 study: documentation of HIV-1 infection by historical data or defined as positive results from two samples collected at different time points. More information on this criterion can be found in the protocol.
  • HIV-uninfected pregnant women must have documented negative HIV antibody test during current pregnancy
  • Participants enrolling in the 3rd trimester must enroll by 34 6/7 weeks gestation
  • Participant can provide legal informed consent per local regulations
  • If a woman has completed this study and becomes pregnant again, she may re-enroll in the study only if she is enrolled in a different arm than that studied during her initial enrollment

Exclusion Criteria:

  • Women on medicines known to interfere with absorption, metabolism, or clearance of the ARV drug being evaluated (see protocol for more information). Rifampicin is permitted for women being evaluated for TB and ARV drug interactions.
  • If pregnant, carrying multiple fetuses
  • Clinical or laboratory toxicity that, in the opinion of the site investigator, would be likely to require a change in the medicine regimen during the period of study
