简要总结
The purpose of the study is to evaluate whether mycophenolate mofetil (MMF) can treat the chronic hyperactivation of the immune system and (partly) prevent the decrease of the CD4+ T-cell count in chronically HIV-1 infected patients who are not treated with antiretroviral therapy (ART). The researchers also want to know what the effect is of treatment with MMF on plasma HIV-1 RNA; progression of disease (occurrence of AIDS defining events or reaching the indication to start ART); and the safety of treatment with MMF in this patient group.
详细描述
*Background: During chronic HIV-1 infection the immune system is chronically hyperactivated. This hyperactivation is considered as the main cause of CD4+ T-cell loss. Furthermore, HIV replicates most efficiently in activated CD4+ T-cells. In this study we try to inhibit the activation of the immune system with mycophenolate mofetil (MMF). Previous studies in which HIV-1 infected patients have been treated with MMF in addition to antiretroviral treatment (ART) have not shown any additional effect, compared to ART alone. In this study MMF will be used without antiretroviral medication.
*Objectives: Primary objective of the study is the evaluation of the effect of MMF on the chronic hyperactivation of the immune system and the decrease of the CD4+ T-cell count in chronically HIV-1 infected patients who are not treated with antiretroviral therapy (ART). Secondary objectives include the evaluation of the effect of MMF on plasma HIV-1 RNA; progression of disease/ reaching of indication to start ART; and the safety of treatment with MMF in this patient group.
*Study Design: This is a multi center, randomized, open-label study, in which patients will be randomized to treatment with mycophenolate mofetil (MMF) 500 mg BID during 48 weeks versus no treatment. In a subgroup of 20 patients ("immunology group", the first 20 patients in the AMC hospital, Amsterdam, the Netherlands) a number of additional immunological measurements will be performed.
The study duration is 60 weeks (48 weeks of treatments with 1 additional visit 12 weeks after cessation of treatment).
*Study Population: Potential participants are adult chronically HIV-1 infected patients, who have never been treated with ART and who according to the present criteria do not need to be treated. CD4+ T lymphocyte count has to be > 250 and <= 450 * 106/L, plasma HIV-1 RNA (viral load) < 10.000 copies/ mL.
