CORK, Ireland, April 23, 2015 /PRNewswire/ — Janssen Sciences Ireland UC, one of the Janssen Pharmaceutical Companies of Johnson & Johnson (Janssen), today announced results for its hepatitis C treatment simeprevir at The International Liver Congress™ 2015 of the European Association for the Study of the Liver (EASL) in Vienna. Late-breaking results from the Phase 3 OPTIMIST-1 and OPTIMIST-2 trials highlight the clinical outcomes of simeprevir in an all-oral combination regimen in a wide range of patients with hepatitis C virus (HCV) infection.

“The new data for simeprevir presented at The International Liver Congress™ confirms its efficacy when combined with sofosbuvir in an all-oral, ribavirin-free regimen for HCV patients, including those who are treatment-naive and treatment-experienced, both with and without cirrhosis,” said Gaston Picchio, hepatitis disease area leader, Janssen. “These data further demonstrate the role of simeprevir within the HCV treatment landscape, as it provides patients with an important therapeutic option.”

The results from the OPTIMIST-1 and OPTIMIST-2 trials are the first Phase 3 data to be presented on simeprevir in combination with sofosbuvir (SMV/SOF) in patients with genotype 1 chronic HCV infection, both with and without cirrhosis. Sofosbuvir is a nucleotide analog NS5B polymerase inhibitor developed by Gilead Sciences, Inc.



“Chronic HCV infection is a leading cause of cirrhosis, and once it is developed, these patients can be very difficult to cure. The results of the OPTIMIST-2 study demonstrate the safety and efficacy of the all-oral regimen of simeprevir and sofosbuvir for genotype 1 chronic HCV patients with cirrhosis,” said Eric Lawitz, M.D., Texas Liver Institute, principal investigator of the OPTIMIST-2 study.

About Hepatitis C
Hepatitis C, a blood-borne infectious disease of the liver and a leading cause of chronic liver disease, is a major global public health concern. Approximately 170 million people are infected with hepatitis C worldwide and 350,000 people per year die from the disease globally. When left untreated, hepatitis C can cause significant damage to the liver, including cirrhosis. Additionally, hepatitis C may increase the risk of developing complications from cirrhosis, which may include liver failure.

About Janssen’s HCV Development Program
The goal of the Janssen hepatitis C virus (HCV) clinical development program is to provide physicians with multiple treatment options in order to offer patients the best possible chance at successful therapy.

Ongoing studies focus on the investigation of the NS3/4A protease inhibitor simeprevir in a number of different treatment combinations and HCV patient populations, including those who are difficult to cure.

Janssen’s HCV pipeline also includes JNJ-56914845, an investigational NS5A replication complex inhibitor currently in Phase 2 studies, and following the acquisition of Alios BioPharma by Johnson & Johnson in November 2014, AL-335, a uridine-based nucleotide analog in Phase 1 development, and AL-516, a guanosine-based nucleotide analog NS5B polymerase inhibitor in pre-clinical development.

These compounds are being developed with the intent of targeting critical steps of the HCV replication cycle. 

About Simeprevir (OLYSIO®)
Simeprevir is an NS3/4A protease inhibitor which has been developed by Janssen Sciences Ireland UC in collaboration with Medivir AB. 

In November 2013, simeprevir was initially approved by the U.S. Food and Drug Administration, and in May 2014, it was granted marketing authorization by the European Commission. Subsequent marketing authorizations have followed in several other countries around the world. Indications vary by market.

Janssen is responsible for the global clinical development of simeprevir and has exclusive, worldwide marketing rights, except in the Nordic countries. Medivir AB retains marketing rights for simeprevir in these countries under the marketing authorization held by Janssen-Cilag International NV.
