About this study

Official title: A Randomized, Open-label, Crossover Trial of the Effect of High-dose Daily HSV-2 Suppressive Therapy on Plasma HIV-1 Levels Among HIV-1/HSV-2 Co-infected Persons

The purpose of this study is to determine whether treating HSV-2 with either valacyclovir or acyclovir is more effective in suppressing HIV-1 virus levels in people co-infected with HIV-1 and HSV-2.

Read the detailed description

Sexual transmission is responsible for the vast majority of HIV-1 infections among adults worldwide. In sub-Saharan Africa, the region hardest hit by the HIV-1 epidemic, HSV-2 prevalences of 30-50% have been seen in the general population with prevalence up to 90% in infected with HIV-1. HSV-2 is common in those with, or at risk for, HIV-1 infection, and HSV-2 reactivation increases HIV-1 acquisition and infectiousness. Recent studies have shown that suppression of HSV-2 has a sustained effect on lowering HIV-1 levels in blood plasma. New data have raised the question whether higher doses of HSV-2 suppressive therapy might be more effective at suppressing HIV-1 levels. Acyclovir and valacyclovir, chosen for use in this study, are safe and effective treatments for decreasing the frequency of HSV-2 reactivation and shedding. The standard dose of acyclovir is 400 mg twice a day. Valacyclovir, a drug that converts to acyclovir after absorption, delivers higher concentrations of acyclovir. 1.5 grams of valacyclovir, will be used to provide a higher dose of acyclovir, and will be compared with the standard dose of 400 mg twice a day of acyclovir.

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing acyclovir and valacyclovir in people with HSV Infection and HIV Infection, run by University of Washington at 1 site in Kenya.

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 8 inclusion and 13 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 8 Apr 2014. 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 Kenya. 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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

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 5 Mar 2014). 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?

Mean Level of HIV-1 RNA in Plasma of Participants While on Acyclovir or Valacyclovir. (time frame: Weekly for 12 weeks per intervention). 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 NCT01026454, 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 8 Apr 2014.
