test albuvirtide in experienced patients

Conditions: HIV Infections; AIDS

Summary: the purpose of this study is to evaluate the efficacy and safety of albuvirtide combined with lopinavir-ritonavir (lpv/r) in hiv-1-infected patients who failed first-line antiretroviral therapy (art).

this was a 48-week, multi-center, open-label, randomized and controlled, non-inferiority phase 3 clinical trial to evaluate the safety and efficacy of albuvirtide combined with lpv/r in hiv-1 infected patients who failed their first-line art and had hiv-1 rna levels ≥ 1000 copies/ml at screening. the trial was conducted in 12 sites in china. subjects meeting inclusion criteria were randomized in a 1:1 ratio to abt group and nrti group, in which the abt group received albuvirtide and lpv/r combination therapy, and nrti group received the standard 3-drug regimen of lpv/r + lamivudine (3tc) + tenofovir (tdf). if tdf was used in the previous regimen or genotypic resistance histories showed primary mutation to tdf, zidovudine (azt) or abacavir (abc) would be used. albuvirtide was given by weekly intravenous infusion and lpv/r was given twice daily orally. a total of 418 subjects were randomized, of whom 401 received at least one treatment.
