简要总结
HIV infection is diagnosed late in a substantial proportion of patients having an increased risk of clinical progression (AIDS, new AIDS-defining event or death). The currently recommended antiretroviral therapy has suboptimal activity in this setting and potent quadruple-drug therapy has not been sufficiently evaluated. Enfuvirtide may be an appropriate candidate as the fourth antiretroviral agent, regarding its activity, its parenteral administration avoiding gastrointestinal symptoms that often lead to interruption of treatment, the lack of pharmacokinetic interactions and the absence of systemic toxicity.
The aim of this study is to investigate, in a comparative intensification trial, the immunological benefit of adding enfuvirtide for 6 months to a conventional antiretroviral therapy in HIV-1 infected and severely immunosuppressed patients, naïve of any antiretroviral treatment.
We postulate that addition of enfuvirtide to a first-line antiretroviral therapy consisting in emtricitabine/tenofovir combined with either efavirenz or lopinavir/r may improve immunological restoration, measured as the proportion of patients with more than 200 CD4 cells per mm3 after 24 weeks of antiretroviral therapy.
详细描述
The purpose of this randomized, open-label study is to evaluate the immunological efficacy of two first-line strategies of antiretroviral therapy:
- emtricitabine/tenofovir disoproxil fumarate coformulated plus efavirenz (or lopinavir/r) intensified by enfuvirtide during the first 24 weeks of therapy.
- emtricitabine/tenofovir disoproxil fumarate coformulated plus efavirenz (or lopinavir/r)
Patients with lymphocytes T CD4+ cell (CD4)count below 100 per mm3, or CD4 cell count below 200 per mm3 and past history or presence of AIDS defining event and naïve of any antiretroviral therapy will be eligible. This multicenter study will enroll 220 patients (n=110 in each arm). The planned duration of the study is 48 weeks from the enrolment of the last subject.
The primary endpoint will be immunological success defined as CD4 cell count above 200 cells per mm3 after 24 weeks of initial treatment. The durability of this response will be evaluated and patients will be followed for 48 weeks.
