About this study

Official title: Efficacy of an HSV2 Genital Herpes Suppressive Treatment on HIV and HSV2 Genital Shedding Among Co-Infected Patients Receiving or Not Antiretroviral Drugs

Genital herpes is a long-life sexually transmitted diseases which infects a large proportion of women in Africa. Its clinical symptoms are painful sores on the genitals, which heals after a few days. HIV infection can worsen genital herpes. In turn, it is possible that genital herpes increases the quantity of HIV secreted at the genital level in women infected by the 2 viruses. This study is dedicated to verify this hypothesis.

Read the detailed description

Infection with Herpes Virus Simplex type 2 (HSV-2) is likely to represent the main cofactor involved in HIV transmission, either through clinical episodes or asymptomatic genital shedding. However, the definite proof of this concept has never been made through randomised controlled trials. Furthermore, the natural history of HSV-2 infection is poorly documented in sub-Saharan Africa, as well as the efficacy of the antiviral drug on virus transmission. The latter can be measured by HSV-2 genital shedding as a proxy.

The objectives of this research programme are to assess the impact of a suppressive treatment for genital herpes on HIV genital shedding among co-infected patients receiving HAART or not needing antiretroviral (ARV) drugs.

In order to achieve these objectives, we propose to perform 2 randomised double blind controlled trials nested within the ongoing cohort of sex workers in Bobo-Dioulasso.

While the increase of HIV transmission by HSV-2 infection stands as our main working hypothesis among HIV positive persons, the specific rationale for individuals taking ARV is the following: Does the potential cofactor effect of genital herpes on HIV remain present when the immunity is built up by ARV? In other words, is HSV-2 infection a public health issue in this group of people. The role of ARV on HIV transmission will also be assessed.

These 2 trials will be performed using exactly the same methodology and the same study treatment. We will use a parallel design with a baseline phase to take into account the important inter-individual variability of genital shedding. Each participant will be its own control. The baseline phase and treatment phases will each consist of 6 visits performed at a 2 weeks interval. The participants will receive either placebo or Valacyclovir 1g/day during the treatment phase (3 months).

The outcomes will be measured using both a qualitative and a quantitative measure of HIV shedding. The analysis will be conducted using an "intention to treat" and a "per protocol" approach.

At the end of our project, the working hypothesis will be much documented in women taking ARV or not. Furthermore, our results will constitute a reference for an upcoming therapeutic vaccine trial.

This work results from the collaboration of the Centre Muraz, the UMR 36 "AIDS and associated diseases" (Montpellier) and the London School of Hygiene \& Tropical Medicine.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Valacyclovir in people with Herpes Genitalis and HIV Infection, run by French National Agency for Research on AIDS and Viral Hepatitis at 1 site in Burkina Faso.

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 3 inclusion and 4 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 7 Jun 2006. 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 Burkina Faso. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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?

To assess the impact of HSV-2 suppressive therapy on HIV shedding among co-infected women taking highly active antiretroviral therapy (HAART) or not needing HAART. 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 NCT00158509, which also lists 4 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 7 Jun 2006.
