Controlled Clinical Trial of Antiviral Cytotoxic T Lymphocyte (CTL) Infusion Following Combination Antiretroviral Drug Therapy for Asymptomatic HIV-1 Infection

Stopped early · Not applicable

Conditions studied: HIV Infections

In brief

To evaluate the safety of anti-HIV CTL therapy in early stage patients and to verify the safety when combined with antiviral therapy with zidovudine/lamivudine/indinavir and low-dose interleukin-2 (IL-2). To compare the effects on plasma and cell-associated viral load following combination drug therapy with and without antiviral CTL in early-stage patients. To study in detail the immune effects of lowering viral burden with antiviral combination drugs with and without T cell infusion on antiviral CTL activity, viral suppression and proliferation, circulating T cell phenotype, T cell apoptosis, CD4 cell numbers, DTH reaction, and inflammatory cytokine levels. In an HIV-infected person, there is an ongoing struggle between HIV replication and host immune control. In the past decade most therapeutic strategies have targeted the virus. This approach has been frustrated by viral mutation to evade drug sensitivity. Promising drugs have recently been approved and there are encouraging sustained results from combination antiviral chemotherapy. However, even the most potent drug regimens do not seem to be curative, may eventually lead to drug resistance and may not completely restore lost immune function. The addition of immune-based therapy to antiviral drugs may lead to better viral control.
