About this study
Official title: Evaluation of the Use of Antiretroviral Regimens Containing Raltegravir for Prophylaxis of Mother-to-child-transmission of HIV Infection in Pregnant Women Presenting With Detectable Viral Load After 32 Weeks of Gestation: a Pilot Study
The current available antiretroviral (ARV) agents make possible a successful treatment of virtually all HIV-infected patients, even those heavily experienced subjects, with a history of previous failure to ARV drugs of different classes. However, some problems are still present, especially for specific populations, like pregnant women and infants. For these groups, most of currently available drugs are not used, because the lack of information on safety, efficacy, and pharmacokinetic/dynamic behavior of ARVs drugs. The mother to child transmission (MTCT) is still a problem in certain areas of the world, especially in resource-limited settings. In some settings, women often present to their first antenatal care visit late in the pregnancy, posing an additional problem: how to effectively treat these patients to assure they will have an undetectable viral load at the moment of delivering? Depending on the plasma viremia magnitude, and viral susceptibility it can take 6 or more weeks to reduce the viral load to less than the desired 1,000 copies of HIV-1 RNA / ml of plasma. To achieve this goal, it would be necessary the use of a potent, very efficacious ARV regimen that could provide such viral decay in a very short period. Raltegravir (RAL), the first HIV-1 integrase inhibitor, is a potent and safe ARV drug. The available evidence suggest it has no genotoxic potential, and promotes a rapid decline in HIV-1 plasma viremia. In addition, RAL is highly active against viral strains presenting different degree of resistance to other ARV drugs. Thus, RAL could be an ideal candidate to be used for prevention of MTCT for women with detectable viral load, presenting late in the course of pregnancy. Another attractive point is to consider that, due to the similarity between the integrase enzyme of HIV-1 and Human T-cell lymphotropic virus type-1 (HTLV-1); RAL could be active against HTLV-1, blocking its replication. If our hypothesis is correct, the use f RAL-containing ARV regimens would reduce the MTCT of both agents. This study has the objective of evaluating the efficacy of RAL containing ARV regimens in reducing the HIV-1 RNA plasma viral load below 50 copies/ml, at the end of pregnancy, for late-presenters pregnant women and to compare the frequency of adverse events for women using RAL-based ARV regimens and comparators, and for their babies.
Read the detailed description
A total of 44 late-presenters (gestational age >28 weeks), HIV-infected pregnant women will be randomly assigned to receive an antiretroviral regimen based on Zidovudine (AZT)+Lamivudine (3TC)+Raltegravir or AZT+3TC+Lopinavir/r (LPV/r). They will be followed up to the delivery, and plasma viral load will be measured. The rate of HIV mother-to-child-transmission will be compared between groups. The newborns will be followed up to 6 months, to register any adverse event during this period of time.

Questions about this trial
What is this clinical trial studying?
A Phase 2/3 study testing Raltegravir and Lopinavir/Ritonavir in people with HIV and Pregnancy, run by Fundação Bahiana de Infectologia at 1 site in Brazil.
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 4 inclusion and 3 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: stopped early, as of the sponsor's last update on 15 Oct 2024. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Brazil. 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 combined phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
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?
Yes. Results are posted in the registry (first posted 15 Oct 2024). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
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?
HIV Viral Load at Delivery (time frame: 2, 4, 6 weeks and at delivery). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
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 15 Oct 2024; AzTrials last refreshed its copy on 8 Nov 2026.
