A Study of the Safety and Effectiveness of Hydroxyurea in Patients on Potent Antiretroviral Therapy and Who Have Less Than 200 Copies/ml of HIV RNA in Their Blood

HIV Infections Clinical Trial

Official title:
A Phase II, Randomized Study of the Safety and Efficacy of Hydroxyurea in Subjects on Potent Antiretroviral Therapy With Less Than 200 Copies/ml of HIV RNA in the Plasma

Clinical Trial Summary

This study compares the safety and effectiveness of continuing your current anti-HIV medications to that of adding or switching some of your anti-HIV medications. It will follow the effect of these medication changes, including the addition of hydroxyurea (HU), on long-term viral suppression. Other medications which may be added include didanosine (ddI) and/or stavudine (d4T). Patients receiving combination antiretroviral therapy with indinavir (IDV), zidovudine (ZDV)(or d4T) and lamivudine (3TC) show viral suppression for two years or more. Discontinuation of one or two of these drugs results in prompt loss of the viral suppression. Other studies show that addition of HU to some reverse transcriptase inhibitor treatments results in increased antiviral effects. This study will provide further information on the effect of adding HU to a treatment regimen with respect to long-term viral suppression.

Clinical Trial Description

Previous ACTG studies show that discontinuation of one or two of a three-drug regimen (IDV, ZDV, 3TC) leads to prompt loss of viral suppression in the plasma. In this trial, it will be determined whether adding hydroxyurea (HU) to a suppressive regimen increases long term viral suppression. Important safety information on the tolerance of HU regimen will be characterized in asymptomatic patients with viral suppression. Patients are equally randomized to one of three arms and receive treatment as follows:Arm A: IDV plus ddI plus d4T plus HU placebo. Arm B: IDV plus ddI plus d4T plus HU. Arm C: IDV plus 3TC/ZDV (or d4T plus 3TC). Patients are monitored every 8 weeks with plasma HIV RNA levels and CD4 cell counts. ;
