Grazoprevir/Elbasvir, Merck’s Investigational Chronic Hepatitis C Therapy, Granted FDA Breakthrough Therapy Designations; New Phase 2 and 3 Data in Multiple HCV Patient Types to be Presented at The International Liver Congress™ 2015
Congress Highlights Include Results from Trials in a Wide Range of HCV Patients -- Patients with Chronic Kidney Disease, HIV Co-infection, Cirrhosis, and Prior Treatment Failures
Company Remains on Track for NDA Filing with the U.S. FDA During First Half of 2015

KENILWORTH, N.J.--(BUSINESS WIRE)--Merck (NYSE:MRK), known as MSD outside of the United States and Canada, today announced that grazoprevir/elbasvir, an investigational single tablet regimen for the treatment of chronic hepatitis C virus (HCV) infection, has received two new Breakthrough Therapy designations from the U.S. Food and Drug Administration (FDA) for the treatment of patients with chronic HCV genotype 4 (GT4) infection, and for the treatment of chronic HCV genotype 1 (GT1) infection in patients with end stage renal disease on hemodialysis. Additionally, the company announced presentations from the broad grazoprevir/elbasvir development program at the upcoming International Liver Congress™. A total of 14 abstracts from studies evaluating grazoprevir/elbasvir are scheduled to be presented, including three from the company’s ongoing Phase 3 pivotal C-EDGE program, one from the pivotal Phase 2b/3 C-SURFERstudy, and seven from ongoing or completed Phase 2 studies. The range of data to be presented underscores the company’s ongoing commitment to developing an all-oral regimen with wide application across diverse patient populations. The International Liver Congress™ 2015 – the 50thannual congress of the European Association for the Study of the Liver – is scheduled to take place at the Reed Messe Convention Center, Vienna, Austria, from April 22 – 26, 2015.
“HCV remains a global public health epidemic. At Merck, we are focused on the development of an efficacious, well-tolerated, once-daily therapy that can be used to treat multiple genotypes and a diverse population of chronic HCV patients,” said Dr. Eliav Barr, vice president, infectious diseases, Merck Research Laboratories. “Our clinical program is among the largest and most comprehensive, with studies dedicated to patient populations where significant unmet medical need still exists, such as prior treatment failures, as well as those living with co-morbid conditions, including HIV infection, chronic kidney disease and individuals on opiate substitution therapy.”
In October 2013, the FDA granted Breakthrough Therapy designation for grazoprevir/elbasvir for the treatment of patients with chronic HCV genotype 1 (GT1). In January 2015, the FDA notified Merck of its intention to rescind that Breakthrough Therapy designation. The FDA has now granted two new Breakthrough Therapy designations for grazoprevir/elbasvir; the designations are now for the treatment of patients infected with chronic HCV GT1 with end stage renal disease on hemodialysis, and patients infected with chronic HCV genotype 4 (GT4). 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.
