Dutch Acute HCV in HIV Study (DAHHS-2): Grazoprevir/Elbasvir for Acute HCV

Summary

New and recently EMA/FDA approved direct acting antiviral (DAA) combination therapies cure 95% or more of the patients chronically infected with HCV genotype 1 and 4. Grazoprevir (MK-5172) and elbasvir (MK-8742) combination therapy is such a, albeit not yet EMA/FDA approved combination DAA therapy. It is likely that the synergistic effect of the host's immune response and antiviral therapy when given during the first 6 months of HCV infection makes antiviral therapy during acute HCV infection more effective. In this study the investigators would like to document that treatment of acute HCV with grazoprevir (MK-5172), elbasvir (MK-8742) is effective and can ben shortened from 12 to 8 weeks for HCV genotype 1 and 4 infection without substantial loss in efficacy. Study design and intervention: Prospective open label interventional clinical trial in which 80 acute HCV genotype 1 or 4 patients co-infected with HIV will receive 8 weeks of grazoprevir and elbasvir (a once-daily combination tablet). Study population: 80 Adult HIV positive patients with an acute HCV genotype 1 or 4 infection from 10 HIV treatment centers in the Netherlands and Belgium will be included. Primary endpoint: Sustained viral response (SVR) 12 weeks after the end of therapy in ITT study population (=genotype 1 and 4).
