Information provided by:	National Institutes of Health Clinical Center (CC)
ClinicalTrials.gov Identifier:	NCT00405821

Purpose

This study will determine whether acyclovir, a medicine used to treat herpes simplex virus 2 (HSV-2), can slow down the progression (worsening) of HIV disease in people with both HIV and HSV-2 infections. HSV-2 increases the amount of HIV virus in the blood of infected people and may make HIV progress faster. The study will evaluate:

"Whether people who take acyclovir can avoid antiretroviral treatment until later in their lives

"Whether people who take acyclovir get fewer genital ulcers

"How well people are able to take acyclovir and any side effects they experience from it

"Differences in the amount of HIV virus in the blood of patients who are and are not taking acyclovir, and how HIV/AIDS is different in these patients.

People 18 years of age and older living in the Rakai district of Uganda who are infected with both HIV (early stage disease) and HSV-2 may be eligible for this study. Participants are randomly assigned to take the study drug, acyclovir, or a placebo (look-alike pill with no active ingredient) daily for 2 years. During this time, they visit the clinic once a month for a routine physical examination. Patients who develop genital ulcers or complications of HIV are treated for the problem, and patients whose HIV disease progresses, requiring them to begin antiretroviral therapy, are treated accordingly.

Detailed Description:

Interventions that slow HIV-1 disease progression among persons with CD4+ counts above 250 cells/microliter could postpone the need for antiretroviral therapy (ART) and prolong life-expectancy for HIV-infected persons. Herpes simplex virus type 2 (HSV-2) has been shown to up-regulate HIV-1 replication at the cellular level. (1) This finding has been supported by clinical evidence that individuals who are HSV-2 seropositive at the time of HIV-1 seroconversion had higher HIV viral loads at 5 and 15 months post-seroconversion. (2) Earlier studies during the era of zidovudine (Retrovir) monotherapy showed a survival advantage when acyclovir (ACV, Zovirax) was added to the treatment of patients with HIV. (3) Acyclovir prophylaxis has been shown to decrease herpes simplex virus infections and varicella-zoster virus infections among HIV infected patients in a meta-analysis of randomized trials from North America and Europe. This analysis also found a reduced risk of mortality among patients treated with acyclovir. The potential of acyclovir to slow HIV-1 disease progression has not been assessed in a randomized trial in Africa where high rates of HSV-2 infection have been observed among HIV-1 infected individuals. This study proposes to assess the benefits of acyclovir prophylaxis among HIV-1 infected individuals dually infected with HSV-2 who are not on ART through a randomized double-blind placebo controlled trial.
