KENILWORTH, N.J.--(BUSINESS WIRE)--Merck (NYSE:MRK), known as MSD outside the United States and Canada, today announced that new data from clinical trials of its investigational treatment portfolio for chronic hepatitis C virus (HCV) are scheduled to be presented at The Liver Meeting® 2015 (the 66th annual scientific congress of the American Association for the Study of Liver Diseases) in San Francisco, from Nov. 13-17, 2015. Merck’s late-stage investigational portfolio includes elbasvir/grazoprevir1, MK-36822 and MK-84083.
A range of data will be presented from more than 20 accepted abstracts. Among these are two late-breaking abstracts from the C-CREST and C-SWIFT clinical trial programs.
“Recent innovations in the treatment of chronic hepatitis C are enabling health systems and physicians to address the burden of this disease. Continued innovation is essential, particularly for patients for whom current therapies may not be suitable,” said Dr. Eliav Barr, vice president, infectious diseases, Merck Research Laboratories. “Merck is committed to evaluating our chronic hepatitis C investigational medicines in a broad range of patients and treatment durations to help address the global unmet needs that still exist.”
Elbasvir/grazoprevir is currently under Priority Review with the U.S. Food and Drug Administration, with a Prescription Drug User Fee Act (PDUFA) action date of Jan. 28, 2016.

Elbasvir/grazoprevir is Merck’s investigational, once-daily, fixed-dose combination therapy containing elbasvir (HCV NS5A replication complex inhibitor) and grazoprevir (HCV NS3/4A protease inhibitor). Merck’s broad clinical trials program includes evaluations of elbasvir/grazoprevir with or without ribavirin for multiple HCV genotypes, together with patients with difficult-to-treat conditions such as cirrhosis, advanced chronic kidney disease, HIV/HCV co-infection, inherited blood disorders and those on opiate substitution therapy. In July 2015, the U.S. Food and Drug Administration (FDA) granted Priority Review for the New Drug Application for elbasvir/grazoprevir, with a Prescription Drug User Fee Act (PDUFA) action date of Jan. 28, 2016.
In April 2015, the FDA granted Breakthrough Therapy designation for elbasvir/grazoprevir for the treatment of patients with chronic HCV GT1 infection with end stage renal disease on hemodialysis, and Breakthrough Therapy designation for elbasvir/grazoprevir for the treatment of patients with chronic HCV GT4 infection. Breakthrough Therapy designation is intended to expedite the development and review of a candidate that is planned for use, alone or in combination, to treat a serious or life-threatening disease or condition when preliminary clinical evidence indicates that the drug may demonstrate substantial improvement over existing therapies on one or more clinically significant endpoints.
