INTRODUCTION MODERN (A4001095) was the first prospective phase 3 study comparing genotype vs phenotype (Trofile™) tropism assessments. MATERIALS AND METHODS Treatment-naïve adults with HIV-1 RNA >1000 copies/mL were randomized 1:1 at screening to either genotype or Trofile for tropism assessment. Genotype was determined using the geno2pheno algorithm to assess triplicate HIV-1 gp120 V3 loop s...
Viral phenotype, tropism, coreceptor usage, and envelope gene diversity were examined in blood isolates collected from 27 individuals at different stages of human immunodeficiency virus type 1 (HIV-1) disease and tissue derived isolates from 10 individuals with AIDS. The majority (89%) of blood and all tissue HIV-1 isolates from all stages of infection were non-syncytium inducing and macrophage...
OBJECTIVE Few data are available about the efficacy of maraviroc (MVC) during routine use. We characterized indications for MVC use and the efficacy of MVC in clinical practice. METHODS Thirty-two patients treated with MVC at our institution between 2006 and 2009 were included. Genotypic (n +/- 31) and phenotypic (n +/- 13) tropism analysis was performed. We determined indications for MVC use...
The human chemokine receptors, CCR5 and CXCR4, are potential host targets for exogenous, small-molecule antagonists for the inhibition of HIV-1 infection. HIV-1 strains can be categorised by co-receptor tropism - their ability to utilise CCR5 (CCR5-tropic), CXCR4 (CXCR4-tropic) or both (dual-tropic) as a co-receptor for entry into susceptible cells. CCR5 may be the more suitable co-receptor tar...
