To address the need for more affordable HCV antivirals with high barriers to viral resistance and/or strategies to shorten the current treatment duration, the goal is to develop affordable therapeutic regimens to prevent HCV entry/spread and test the efficacy of those inhibitors for treating HCV infection. The investigators recently discovered that the Niemann-Pick C1 Like-1 (NPC1L1) cellular cholesterol uptake receptor is required for HCV entry into hepatocytes and that ezetimibe, an FDA-approved drug that inhibits NPC1L1-mediated cholesterol uptake potently blocks HCV entry in human hepatoma cells and human hepatocytes transplanted into urokinase-type plasminogen activator-severe combined immunodeficiency (uPA-SCID) mice. Further, retrospective analysis of the National VA database using multivariable logistic regression models to control for age, sex, race, alcohol use, drug use, and other co-morbidities, the investigators found HCV prevalence to be lower (p <.001) and interferon/ribavirin (IFN/RBV) treatment response to be better (i.e. larger viral log reduction) in patients taking ezetimibe. Hence, the specific objective of this application is to assess the efficacy of EZE for the treatment of chronic HCV. Based on preliminary in vitro, in vivo, clinical retrospective data and HCV/DAA modeling, the investigators hypothesize that when administered as monotherapy EZE will reduce HCV viremia perhaps allowing for viral clearance and that when included in combination treatment regimens that EZE will augment 2nd phase HCV decline resulting in faster viral clearance (i.e. shorter/cheaper DAA therapy). To test these hypotheses, the investigators will execute the following aims: (1) Assess the efficacy of EZE monotherapy in chronically HCV infected and predict time to cure; (2) Assess the efficacy of EZE as an adjunct therapy in chronically HCV infected patients undergoing currently approved HCV DAA treatment.
