  Purpose

We propose to study the episode rate, duration, and quantity of HSV-2 genital shedding in patients taking standard, FDA approved, CDC recommended doses of acyclovir (400 mg PO BID) for HSV-2 suppression compared to taking no medication to better define the effect of acyclovir on short bursts of rapidly cleared HSV-2 shedding. This study will be a randomized, open label, cross-over trial. We hypothesize that short bursts of HSV-2 reactivation will not be suppressed by acyclovir.

Primary Outcome Measures:
  • Frequency of HSV-2 total shedding from the genital tract as measured by PCR, calculated using a per-day shedding rate in participants treated with suppressive acyclovir as compared to no medication in HIV sero-negative AND HIV seropositive individuals. [ Time Frame: 9 weeks ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Frequency of subclinical shedding from the genital tract as measured by PCR, calculated using a per-day shedding rate in participants treated with with suppressive acyclovir as compared to no medication. [ Time Frame: 9 weeks ] [ Designated as safety issue: No ]
  • Frequency of lesional shedding from the genital tract as measured by PCR, calculated using a per day shedding rate in participants treated with with suppressive acyclovir as compared to no medication. [ Time Frame: 9 weeks ] [ Designated as safety issue: No ]
  • Number of herpes recurrences, defined clinically as >=1 successive day on which genital lesions are present, in participants treated with with suppressive acyclovir as compared to no medication. [ Time Frame: 9 weeks ] [ Designated as safety issue: No ]

Detailed Description:

We propose to study the episode rate, duration, and quantity of HSV-2 genital shedding in patients taking standard, FDA approved, CDC recommended doses of acyclovir (400 mg PO BID) for HSV-2 suppression compared to taking no medication to better define the effect of acyclovir on short bursts of rapidly cleared HSV-2 shedding. This study will be a randomized, open label, cross-over trial.

We propose to perform this study in two study populations. Cohort 1 will be comprised of 25 HSV-2 seropositive, HIV seronegative adults, and Cohort 2 will be comprised of 25 HSV-2 seropositive, HIV seropositive adults with a CD4 count>250 cells/mm3. As suppression of HSV-2 using acyclovir is currently being studied in large, multi-center, international clinical trials as an HIV prevention strategy, these results will have broad implications for public health around the world.
