Ledipasvir-Sofosbuvir +/- [GS-9669 or GS-9451] in Naïve GT1NIH SYNERGY Trial: Features

NIH SYNERGY Trial Design: Open-label, phase 2, using fixed dose ledipasvir-sofosbuvir alone

or in combination with either GS-9669 (non-nucleoside NS5B inhibitor) or GS-9451 (NS3/4A protease inhibitor) in treatment-naïve GT 1

Setting: single site, United States Entry Criteria

- Chronic HCV Genotype 1- Treatment naive- HCV RNA > 50,000 IU/mL

Patient Characteristics- N = 60 adult patients- Demographics: 72% male; 88% black- IL28B Genotype: 80% with non-CC- Liver Fibrosis: 70% Knodell HAI Fibrosis score 0-2

Primary End-Point: SVR12
