About this study

Official title: A Phase III Randomized Trial of the Safety and Antiretroviral Effects of Zidovudine/Lamivudine/Abacavir Versus Zidovudine/Lamivudine/Lopinavir/Ritonavir in the Prevention of Perinatal Transmission of HIV

Pregnant women infected with HIV who take anti-HIV medications during pregnancy lower the risk of passing HIV to their infants. This study will compare how well two different combinations of anti-HIV medications control HIV in pregnancy, and whether these combinations of drugs are effective in preventing HIV from being transmitted from a pregnant woman to her baby. The two combinations are abacavir/lamivudine/zidovudine (ABC/3TC/ZDV) and zidovudine/lamivudine (ZDV/3TC) plus lopinavir/ritonavir (LPV/RTV).

Read the detailed description

Antiretroviral therapy (ART) in pregnancy has dramatically reduced the rates of perinatal HIV transmission. Many pregnant women infected with HIV may not meet the criteria for treatment as set forth by the Department of Health and Human Services' guidelines and would not be started on therapy if they were not pregnant. Pregnant women are prescribed a variety of treatment regimens; the optimum regimen for pregnant women who plan to discontinue therapy after delivery is unknown. An optimum regimen would account for the need for maximum viral suppression, minimal fetal toxicity, and preservation of future therapeutic options for the mother. This study will compare an all nucleoside reverse transcriptase inhibitor (NRTI) regimen of ABC/3TC/ZDV with a standard protease inhibitor (PI) regimen of LPV/RTV and 3TC/ZDV. This study was initially designed for women who plan to take antiretrovirals only while pregnant and do not meet the criteria for treatment initiation if not pregnant. However, pregnant women who have taken ART for 180 days or less or have taken ZDV monotherapy for a total of 8 weeks or less prior to entering this study are eligible for Version 2.0 of this study.

Women in this study will be randomly assigned to one of two groups. Women in Group A will receive one pill ABC/3TC/ZDV twice a day. Women in Group B will receive one pill 3TC/ZDV and 4 pills LPV/RTV twice a day. Women will take their assigned medications until they go into labor. Once in labor, women will be given zidovudine through intravenous (IV) infusion; they will stop taking oral zidovudine but will continue with their other medications. After delivery, all infants will be given zidovudine for six weeks.

Women will have study visits every 2 weeks for the first 8 weeks of treatment, and then every 4 weeks until Week 28. Depending on where a woman is in her pregnancy when she enrolls in the study, she will also have study visits at Weeks 20, 28, and 34 of her pregnancy. At each visit, women will have a medical interview, a physical exam, and an obstetrical exam; blood and urine collection will occur at these visits. Mothers will undergo a fetal ultrasound at Week 20. Adherence, health status, and behavior assessments will occur at selected visits prior to delivery.

After delivery, women will stop taking the study medications but will continue to have study visits at approximately 6, 12, 24, 36, 48, and 52 weeks after delivery. Medical history and a physical exam will occur at all visits for mothers postpartum. Blood collection will occur at every postpartum visit; urine collection will occur 12, 24, and 48 weeks postpartum; health status and behavior assessments will occur at most visits postpartum. Infants will have study visits at 2, 16, and 24 weeks after birth. A medical history, physical exam, and laboratory tests will be conducted at the infant study visits. Women will also be asked to enroll their infants in PACTG 219C, a long-term study that follows infants who are born to HIV infected mothers.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Proportion of women in each treatment group with virologic suppression to less than 400 copies/ml at 34th week of pregnancy (or last viral load prior to delivery, if delivery occurs before 34th week of pregnancy) while continuing on assigned therapy

    Measured: at Week 34 of pregnancy

Secondary outcomes (9)
  1. Primary outcome, evaluating ART naive and ART experienced women

    Measured: throughout study

  2. HIV-related health status of women at delivery, determined by CD4 counts and plasma HIV-1 viral load in the two treatment groups and in ART naive and ART experienced women

    Measured: throughout study

  3. study treatment adherence and health status by self report

    Measured: throughout study

  4. HIV-related health status of women postpartum, determined by CD4 counts and plasma HIV-1 viral load

    Measured: at Months 3, 6 and 12 postpartum and prior to ART treatment

  5. development of HIV-1 genotypic resistance among women in each treatment group

    Measured: at delivery, Months 3, 6, and 12 postpartum, and in all cases of treatment failure

  6. incidence of abnormal glucose tolerance, gestational diabetes, and abnormal lactate levels during pregnancy in each treatment group

    Measured: throughout study

  7. incidence of anemia, hypoglycemia, abnormal liver function studies, prematurity, low birth weight, or perinatal HIV transmission among infants born to women in each treatment group

    Measured: throughout study

  8. predictive value, sensitivity, and specificity of polymorphisms in HLA-B57, HLA-DR7, and HLA-DQ3 in identifying pregnant women at risk for development of ABC hypersensitivity

    Measured: throughout study

  9. concentration of T cell receptor rearrangement excision DNA circles

    Measured: at study entry, delivery and 6 weeks postpartum

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Abacavir sulfate, lamivudine, and zidovudine, Lamivudine/zidovudine and Lopinavir/ritonavir in people with HIV Infections, run by National Institute of Allergy and Infectious Diseases (NIAID) at 8 sites in 2 countries.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 10 inclusion and 12 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 1 Nov 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 8 sites in United States, Puerto Rico. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Proportion of women in each treatment group with virologic suppression to less than 400 copies/ml at 34th week of pregnancy (or last viral load prior to delivery, if delivery occurs before 34th week of pregnancy) while continuing on assigned therapy (time frame: at Week 34 of pregnancy). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00086359, which also lists 5 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 1 Nov 2021.
