Janssen Submits Supplemental New Drug Application to U.S. FDA for All-Oral, Once-Daily OLYSIO® (Simeprevir) in Combination with Sofosbuvir

Filing Supported by Data from the Phase 3 OPTIMIST-1 and -2 Clinical Trials Evaluating OLYSIO® Combination Therapy in Hepatitis C Patients with and without Cirrhosis

TITUSVILLE, N.J., July 23, 2015 /PRNewswire/ -- Janssen Therapeutics, Division of Janssen Products, LP (Janssen), today announced the submission of a supplemental New Drug Application (sNDA) to the U.S. Food and Drug Administration (FDA) to update the label for once-daily, all-oral OLYSIO^® (simeprevir). OLYSIO^® is a hepatitis C virus (HCV) NS3/4A protease inhibitor, currently approved for use with sofosbuvir for adults with genotype 1 chronic hepatitis C (CHC) infection as a 12-week treatment for patients without cirrhosis or a 24-week treatment regimen for patients with cirrhosis. Sofosbuvir is a nucleotide analog NS5B polymerase inhibitor marketed by Gilead Sciences, Inc.

OLYSIO^® was approved in November 2014 in combination with sofosbuvir based on the Phase 2 COSMOS clinical trial. This sNDA is based on results from the Phase 3 OPTIMIST-1 and OPTIMIST-2 trials, which evaluated 12 and eight weeks of therapy for treatment-naive and treatment-experienced genotype 1 CHC adult patients without cirrhosis, and 12 weeks of therapy for treatment-naive and treatment-experienced genotype 1 CHC adult patients with cirrhosis.

"OLYSIO^® has contributed significantly to the care of people living with hepatitis C. The availability of multiple treatment options is important to help offer an opportunity for cure, and we believe OLYSIO^® will continue to play a meaningful role going forward," said Richard Nettles, M.D., vice president, Medical Affairs, Janssen Therapeutics. "We're pleased to submit the data from the Phase 3 OPTIMIST trials, which adds to the body of clinical information about this combination in patients with and without cirrhosis."

Results from the OPTIMIST trials were presented in April 2015 at The International Liver Congress™ 2015 of the European Association for the Study of the Liver (EASL) in Vienna.

About the OPTIMIST TrialsOPTIMIST-1 is a Phase 3, randomized, open-label trial to investigate the efficacy and safety of the all-oral regimen of simeprevir and sofosbuvir (SMV/SOF) among treatment-naive and treatment-experienced genotype 1 CHC patients without cirrhosis. The primary study endpoint is sustained virologic response (SVR) at 12 weeks after treatment (SVR12) with 12 and eight weeks of treatment with SMV/SOF versus a historical control (patients previously treated with approved regimens containing a direct-acting antiviral, pegylated interferon and ribavirin).

• Ninety-seven (97) percent of patients treated with SMV/SOF for 12 weeks (n=150/155) achieved SVR12, which was superior to the SVR12 rate of 87 percent among the historical control.
  • SVR12 rates of 100 percent were seen among patients with IL28B CC genotype (n=43/43) and those with baseline NS5A and NS3 Q80K polymorphisms (n=9/9).
• Patients treated with eight weeks of SMV/SOF achieved an SVR12 rate of 83 percent (n=128/155), which was not superior to the SVR12 rate of 83 percent in the historical control.
  • High SVR12 rates were seen among patients with baseline HCV RNA < 4 million IU/mL (96 percent; n=46/48), IL28B CC genotype (93 percent; n=38/41), patients with genotype 1b CHC (92 percent; n=36/39) and patients without baseline NS5A and Q80K polymorphisms (89 percent; n=78/88).
• The most frequently reported adverse events in the 12- and eight-week treatment arms were headache (14 and 17 percent, respectively), fatigue (12 and 15 percent, respectively) and nausea (15 and 9 percent, respectively).

OPTIMIST-2 is a Phase 3, open-label, single-arm trial to investigate the efficacy and safety of SMV/SOF in treatment-naive and treatment-experienced genotype 1 CHC patients with cirrhosis. The primary endpoint is SVR12 with SMV/SOF versus a historical control.

• Twelve (12) weeks of treatment with SMV/SOF resulted in SVR12 rates of 84 percent (n=86/103), which was superior to the SVR12 rate of 70 percent in the historical control.
• Higher SVR12 rates were seen in patients with baseline NS5A polymorphisms with or without NS3 Q80K polymorphisms (100 percent; n=13/13), patients with albumin ≥4 g/dL (94 percent; n=47/50) and treatment-naïve patients (88 percent; n=44/50).
• The most common adverse events were fatigue (20 percent), headache (20 percent) and nausea (11 percent).

Merck Submits U.S. New Drug Application for Grazoprevir/Elbasvir, an Investigational Once-Daily, Single Tablet Combination Therapy, for Treatment of Chronic Hepatitis C Genotypes 1, 4, and 6 Infection

KENILWORTH, N.J.--(BUSINESS WIRE)--Merck (NYSE:MRK), known as MSD outside the United States and Canada, today announced that the company has submitted a New Drug Application to the U.S. Food and Drug Administration (FDA) for grazoprevir/elbasvir (100mg/50mg), an investigational once-daily, single tablet combination therapy for the treatment of adult patients with chronic hepatitis C genotypes (GT) 1, 4 or 6 infection. Within 60 days of submission, the FDA will determine whether it will accept for review Merck's application as filed. The company plans to submit additional license applications in the European Union and other markets by the end of 2015.

“Merck's submission is based on evidence from our wide-ranging clinical program assessing the efficacy and tolerability profile of grazoprevir/elbasvir in populations with chronic hepatitis C,” said Dr. Roy Baynes, senior vice president of clinical development, Merck Research Laboratories. “This submission to the U.S. FDA is an important milestone as we seek to provide patients with a new treatment option for this serious infection.”

The FDA has previously granted Breakthrough Therapy designation status for grazoprevir/elbasvir for the treatment of patients infected with chronic HCV GT1 with end stage renal disease on hemodialysis, and for patients infected with chronic HCV 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.

The New Drug Application for grazoprevir/elbasvir (100mg/50mg) is based in part upon data from the pivotal C-EDGE clinical trials program, as well as the C-SURFER and C-SALVAGE trials, evaluating grazoprevir/elbasvir (100mg/50mg), with or without ribavirin, in patients with chronic hepatitis C infection. Data from these trials were presented at The International Liver Congress^TM 2015 in April 2015.
