Merck announced that new data from the company’s chronic hepatitis C virus (HCV) clinical development programs as well as real-world studies on ZEPATIER® (elbasvir and grazoprevir) 50mg/100mg tablets will be presented at the upcoming International Liver Congress™ 2017. Seventeen scientific abstracts will be presented, including oral sessions featuring real-world data on chronic HCV-infected patients treated with ZEPATIER from the U.S. Department of Veterans Affairs Healthcare System and new results from the C-SURGE trial evaluating MK-3682B [uprifosbuvir (MK-3682)1/grazoprevir2/rusazvir3] in patients with chronic HCV infection who have previously failed a HCV direct-acting antiviral regimen. The International Liver Congress™ 2017 will take place in Amsterdam, Netherlands from April 19 " 23, 2017. In the United States, ZEPATIER is indicated for the treatment of chronic HCV genotype (GT) 1 or GT4 infection in adults. ZEPATIER is indicated for use with ribavirin (RBV) in certain patient populations. The U.S. Prescribing Information for ZEPATIER contains a Boxed Warning about the risk of hepatitis B virus (HBV) reactivation in patients co-infected with HCV and HBV.
