Trial to Study the Effect of Dose of Herpes Simplex Virus-2 (HSV-2) Suppressive Therapy on HSV and HIV
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

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 the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
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)
|
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.
|
26 weeks (12 weeks per drug intervention)
|
The Genital HSV Shedding Rate While on 400 mg Twice Daily of Acyclovir Versus 1000 mg Twice Daily of Valacyclovir.
Time Frame: The first four weeks of each intervention
|
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.
|
The first four weeks of each intervention
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
The Effect of Valacyclovir 1 Gram Twice Daily Compared to Acyclovir 400 mg Twice Daily on the Percentage of Days With Genital Herpes Lesions.
Time Frame: 26 weeks (12 weeks per drug intervention)
|
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.
|
26 weeks (12 weeks per drug intervention)
|
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.
Time Frame: The first four weeks of each intervention
|
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.
|
The first four weeks of each intervention
|
Sub-Study: To Evaluate the Kinetics of Plasma HIV-1 Decline Over the First Three Days of High-dose Valacyclovir Administration.
Time Frame: 72 hours
|
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.
