Merck to Present New Data on ZEPATIER® (elbasvir and grazoprevir) for the Treatment of Chronic Hepatitis C Virus Infection at The Liver Meeting® 2017

Merck (NYSE:MRK), known as MSD outside of the United States and Canada, today announced that data from the company's chronic hepatitis C clinical development programs and real-world studies are scheduled to be presented at The Liver Meeting^® 2017. These data presentations include new analyses of ZEPATIER^® (elbasvir and grazoprevir) in real-world settings and follow-up analyses from Phase 3 clinical trials, including findings from the C-EDGE CO-STAR three-year observational follow-up study evaluating chronic hepatitis C virus (HCV) reinfection incidence and risk behaviors in patients who were treated with ZEPATIER while on opioid agonist therapy (OAT). The Liver Meeting^® 2017 will take place in Washington, D.C., from Oct. 20-24, 2017.

"Merck has been a leader in chronic hepatitis C for more than 30 years. Now, with the availability of treatments such as ZEPATIER, we believe our focus needs to be on understanding its application in the real world," said Dr. Michael Robertson (News - Alert), executive director of clinical research, Merck Research Laboratories. "Analysis of data from patients treated with ZEPATIER around the world provides important insights that may help inform elimination efforts, particularly among difficult-to-treat populations."

In the United States, ZEPATIER is indicated for the treatment of chronic HCV genotype (GT) 1 or 4 infection in adults. ZEPATIER is indicated for use with ribavirin 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 coinfected with HCV and HBV.
Key presentations at The Liver Meeting^® 2017 will include:
ZEPATIER^® (elbasvir and grazoprevir) 50mg/100mg tablets
