Salvage Therapy With Amprenavir, Lopinavir and Ritonavir in HIV-Infected Patients in Virological Failure. - Full Text View

Purpose

HIV infected patients are treated with highly active antiretroviral therapy (HAART). Side effects and the great number of pills reduces adherence to the treatment, and induces therapeutic failure. In order to maintain efficacy of HAART, new combination is evaluated. The aim of the study is to compare the antiviral efficacy of this salvage therapy combining lopinavir and amprenavir with 200 mg/d or 400 mg/d ritonavir, together with nucleoside reverse transcriptase inhibitors, over a 26-week period in HIV-infected patients in whom multiple antiretroviral regimens had failed.

Detailed Description:

HIV infected patients are treated with highly active antiretroviral therapy (HAART). Side effects and the great number of pills reduces adherence to the treatment, and induces therapeutic failure. In order to maintain efficacy of HAART, new combination is evaluated. The aim of the study is to compare the antiviral efficacy of this salvage therapy combining lopinavir and amprenavir with 200 mg/d or 400 mg/d ritonavir, together with nucleoside reverse transcriptase inhibitors (NRTI), over a 26-week period in HIV-infected patients in whom multiple antiretroviral regimens had failed. 100 patients with CD4 cell count below 300/mm3 and plasma HIV RNA over 30,000 copies/ml are to be included in four groups: amprenavir, lopinavir, NRTI, with ritonavir 200 mg.d or not (patients previously treated by additional ritonavir 200 or 400 mg/d).
