OREANDA-NEWS. Merck (NYSE:MRK), known as MSD outside of the United States and Canada, today announced that new data from the company’s chronic hepatitis C virus (HCV) clinical development programs will be presented at The Liver Meeting® 2016. Fifteen scientific abstracts, including seven oral and eight poster presentations, will highlight findings from Merck’s HCV clinical development programs. The data include evaluations of ZEPATIER™ (elbasvir and grazoprevir) 50mg/100mg tablets and the company’s investigational MK-3682B (MK-36821/grazoprevir2/rusazvir) in a broad range of patients with chronic HCV infection. The Liver Meeting® 2016 will take place in Boston, MA, from November 11-15, 2016.

“Merck has been a part of the fight against chronic hepatitis C infection for more than 30 years, and that fight continues. Chronic hepatitis C is a complex infectious disease that affects tens of millions of patients globally, each with their own personal circumstances, co-morbidities and challenges,” said Dr. Eliav Barr, senior vice president, global clinical development, infectious diseases and vaccines, Merck Research Laboratories. “At AASLD this year, researchers will share data from numerous studies that are underway to better understand the potential of ZEPATIER and our investigational medicines in diverse patient populations.”

Key presentations at The Liver Meeting® 2016 will include:

About ZEPATIER™ (elbasvir and grazoprevir) 50mg/100mg Tablets

ZEPATIER is a fixed-dose combination product containing elbasvir, a HCV NS5A inhibitor, and grazoprevir, an HCV NS3/4A protease inhibitor. In the United States, ZEPATIER is indicated with or without ribavirin (RBV) for treatment of chronic HCV GT1 or 4 infection in adults. ZEPATIER is not indicated to treat chronic HCV GT3 or GT6 infection. ZEPATIER was approved in the United States on January 28, 2016 and is also approved in the European Union, Canada, Japan, Australia, Saudi Arabia, Israel and Switzerland, with additional regulatory approvals anticipated.

Selected Safety Information about ZEPATIER

ZEPATIER is not for use in patients with moderate or severe hepatic impairment (Child Pugh B or C). ZEPATIER is also not for use with organic anion transporting polypeptides 1B1/3 (OATP1B1/3) inhibitors (e.g., atazanavir, darunavir, lopinavir, saquinavir, tipranavir, cyclosporine), strong cytochrome P450 3A (CYP3A) inducers (e.g., carbamazepine, phenytoin, rifampin, St. John’s Wort), and efavirenz. If ZEPATIER is administered with RBV, healthcare professionals should refer to the prescribing information for RBV as the contraindications, warnings and precautions, adverse reactions and dosing for RBV also apply to this combination regimen.

Elevations of alanine transaminase (ALT) to greater than 5 times the upper limit of normal (ULN) occurred in 1% of subjects, generally at or after treatment week 8. These late ALT elevations were typically asymptomatic and most resolved with ongoing or completion of therapy. Healthcare professionals should perform hepatic lab testing on patients prior to therapy, at treatment week 8, and as clinically indicated. For patients receiving 16 weeks of therapy, additional hepatic lab testing should be performed at treatment week 12.

Patients should be instructed to consult their healthcare professional without delay if they have onset of fatigue, weakness, lack of appetite, nausea and vomiting, jaundice or discolored feces. Healthcare providers should consider discontinuing ZEPATIER if ALT levels remain persistently greater than 10 times ULN. ZEPATIER should be discontinued if ALT elevation is accompanied by signs or symptoms of liver inflammation or increasing conjugated bilirubin, alkaline phosphatase, or international normalized ratio.

The concomitant use of ZEPATIER with certain drugs may lead to adverse reactions or reduced therapeutic effect due to drug interactions. Certain strong CYP3A inhibitors may increase the plasma concentration of ZEPATIER, leading to possibly clinically significant adverse reactions. Moderate CYP3A inducers may decrease the plasma concentration of ZEPATIER, leading to reduced therapeutic effect and possible development of resistance. Coadministration of ZEPATIER with these drugs is not recommended. Physicians should consult the Prescribing Information for potential drug interactions.

In subjects receiving ZEPATIER for 12 weeks, the most commonly reported adverse reactions of all intensity (greater than or equal to 5% in placebo-controlled trials) were fatigue, headache and nausea. In subjects receiving ZEPATIER with RBV for 16 weeks, the most commonly reported adverse reactions of moderate or severe intensity (greater than or equal to 5%) were anemia and headache.

Selected Dosage and Administration Information for ZEPATIER (elbasvir and grazoprevir)

ZEPATIER is a single tablet taken once daily. The recommended dosing is 12 or 16 weeks with or without RBV, depending on HCV genotype, prior treatment history and, for patients with genotype 1a infection, presence of certain baseline NS5A resistance-associated polymorphisms. See Prescribing Information for ZEPATIER for specific dosage regimens and durations. Refer to RBV prescribing information for RBV dosing and dosage modifications when ZEPATIER is given with RBV. To determine dosage regimen and duration of ZEPATIER for genotype 1a patients, testing for the presence of virus with one or more baseline NS5A resistance-associated polymorphisms at positions 28, 30, 31, or 93 is recommended prior to initiating treatment.
