About this study

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

To compare the effect of high-dose valacyclovir (1 gram orally twice daily) versus standard-dose acyclovir (400 mg orally twice daily) on the frequency of genital HSV reactivation and on plasma HIV-1 levels among HSV-2/HIV-1 co-infected individuals. The investigators hypothesize that high-dose valacyclovir will result in greater reduction in plasma HIV-1 and genital HSV reactivation.

Read the detailed description

We propose to conduct a randomized, open-label, cross-over study of 38 individuals who are HIV-1 seropositive and HSV-2 seropositive. Both men and women will be recruited for the study. Participants must not be on antiretroviral therapy and must not be planning to initiate antiretroviral therapy during the anticipated study period. Participants will be randomized 1:1 to receive acyclovir 400 mg twice daily or valacyclovir 1000 mg twice daily. After 12 weeks on the initial treatment, each participant will be crossed over to the alternative treatment arm for 12 weeks. The treatment periods will be separated by a 2-week washout period. During the first four weeks of each treatment period (i.e. weeks 1-4 and weeks 15-18), participants will provide self-collected genital swabs daily for HSV DNA quantification. Each week during the entire study period plasma samples will be collected from participants for HIV-1 RNA quantification.

Open-label acyclovir and valacyclovir will be used for this trial, as the primary outcome measures (genital HSV and plasma HIV-1) are unlikely to be influenced by knowledge of treatment assignment. However, laboratory staff performing plasma HIV-1 and genital HSV measurements will not be aware of treatment assignment.

Optional Sub-Study A: Sub-study A will be offered to study participants. The purpose of sub-study A is to measure the effect of valacyclovir twice daily on plasma HIV-1 replication.

What is being measured

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

  1. The Quantity of HIV-1 RNA in Plasma While on 400 mg Twice Daily of Acyclovir Versus 1000 mg Twice Daily of Valacyclovir.

    Weekly measurements of plasma HIV-1 RNA on each drug were compared. The primary analysis was of the average difference in plasma HIV-1 RNA on valacyclovir and acyclovir as determined by a linear mixed model. The median of the average per-participant plasma HIV-1 RNA levels on valacyclovir and valacyclovir is also listed.

    Measured: 26 weeks (12 weeks per drug intervention)

  2. The Genital HSV Shedding Rate While on 400 mg Twice Daily of Acyclovir Versus 1000 mg Twice Daily of Valacyclovir.

    HSV DNA quantitated from daily self-collected genital swabs for the first four weeks of each drug intervention. The shedding rate was determined by the combined number of swabs with HSV detected divided by the combined number of swabs collected from participants, multiplied by 100.

    Measured: The first four weeks of each intervention

Secondary outcomes (3)
  1. The Effect of Valacyclovir 1 Gram Twice Daily Compared to Acyclovir 400 mg Twice Daily on the Percentage of Days With Genital Herpes Lesions.

    The percentage of days with genital herpes lesions was determined by the combined diary days in which genital lesions were recorded divided by the combined number of diary days for participants in the first four weeks of each drug intervention, multiplied by 100.

    Measured: 26 weeks (12 weeks per drug intervention)

  2. The Effect of Valacyclovir 1 g Twice Daily Compared With Acyclovir 400 mg Twice Daily on the Quantity of Genital HSV Detected During Shedding Episodes.

    HSV DNA was quantitated from daily self-collected genital swabs for the four weeks of each drug intervention. The quantity of genital HSV DNA present, when HSV DNA was detected, was compared.

    Measured: The first four weeks of each intervention

  3. Sub-Study: To Evaluate the Kinetics of Plasma HIV-1 Decline Over the First Three Days of High-dose Valacyclovir Administration.

    Plasma HIV-1 RNA was measured one day prior to, at initiation, and at 6, 24, 48, and 72 hours after initiating valacyclovir. Measurements at 24, 48, and 72 hours were used to determine the rate of HIV-1 RNA decline.

    Measured: 72 hours

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing valacyclovir and acyclovir in people with Genital Herpes and HIV Infection, run by University of Washington at 1 site in United States.

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 7 Jun 2018. 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 United States. 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 31 Jul 2012). 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?

The Quantity of HIV-1 RNA in Plasma While on 400 mg Twice Daily of Acyclovir Versus 1000 mg Twice Daily of Valacyclovir. (time frame: 26 weeks (12 weeks per drug intervention)). The study lists 2 primary outcomes in all. 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 7 Jun 2018.
