Genotypic Tropism Testing In Proviral Dna To Guide CCR5 Antagonist Treatment In Subjects With Undetectable HIV-1 Viremia
Use Of Genotypic HIV-1 Tropism Testing In Proviral DNA To Guide CCR5 Antagonist Treatment In Subjects With Undetectable HIV-1 Viremia
Tutkimuksen yleiskatsaus
Yksityiskohtainen kuvaus
The assessment of HIV-1 tropism is needed before starting treatment with a CCR5-antagonist. Several phenotypic and genotyping tropism tests have been developed in the recent years. Phenotypic assays (i.e. TrofileTM and ES-TrofileTM) have been used.in most clinical trials. Genotypic tropism testing, however, is easier, cheaper and faster than phenotypic methods, and can be performed in a local HIV laboratories.
Viral RNA amplification is difficult in subjects with HIV-1 RNA levels <500-1000 copies/mL. In these cases, the optimal source of genetic material is peripheral blood mononuclear cell (PBMC)-associated proviral DNA. Whereas genotypic tropism testing in proviral DNA is technically feasible, it has not been validated as a tool to predict sustained virological response to CCR5-antagonist therapy in subjects with undetectable viremia.
As of today, maraviroc is the only CCR5-antagonist approved for HIV treatment. It has few drug interactions and a good security profile, particularly in terms of lipid and glucose metabolism. Therefore, it might be an adequate alternative for HIV-1-infected individuals with suppressed viremia who experience antiretroviral-related toxicity or metabolic problems.
This study will evaluate 48-week virological outcomes in aviremic subjects with an R5 virus by proviral genotypic tropism testing who switch the "third drug" of their regimen to maraviroc.
