JANSSEN

Janssen Sciences Ireland UC, one of the Janssen Pharmaceutical Companies of Johnson & Johnson (Janssen), today announced that clinical data for simeprevir, its NS3/4A protease inhibitor for the treatment of hepatitis C virus (HCV) infection, will be presented at The International Liver Congress™ 2015 of the European Association for the Study of the Liver (EASL) taking place in Vienna from April 22-26. Early-stage data on the investigational nucleotide analog polymerase inhibitors AL-335 and AL-516, which were recently obtained through Janssen’s acquisition of Alios BioPharma, will also be presented.

Several key presentations will report on the efficacy and tolerability of simeprevir in interferon-free combination regimens in Phase 2, Phase 3 and real-world clinical settings.

“Hepatitis C remains a serious health problem. The breadth of data we are presenting at The International Liver Congress™ reinforces our commitment to reducing the significant burden of this infectious disease around the world,” said Gaston Picchio, hepatitis disease area leader, Janssen. “Janssen has an extensive and ongoing clinical trial programme for hepatitis C, including confirmatory and new exploratory studies, and we look forward to sharing these results. We remain focused on investigating alternative and more immediate treatment options for patients with a high unmet need.”

A total of 14 company-sponsored abstracts supporting Janssen’s marketed and investigational therapies for HCV will be presented, including three abstracts on simeprevir accepted as late-breaking presentations. The scope and rigor of these data underscore Janssen’s commitment to being a positive catalyst in the fight against this serious public health threat.

“These data highlight the strength of our commitment to advancing research in the area of viral hepatitis,” said Lawrence M. Blatt, Ph.D., global head therapeutics, Janssen Infectious Diseases and Vaccines, and president and chief executive officer of Alios BioPharma. “We are delighted to present additional data for simeprevir in combination with other currently available therapeutic options alongside early-stage data for our nucleotide portfolio.”

Studies on Janssen’s HCV portfolio to be presented at The International Liver Congress™ 2015 include:

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 worldwide¹⁵ and 350,000 people per year die from the disease globally¹⁶ with 86,000 deaths in the European region each year.¹⁷ 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.¹⁸

About Janssen’s HCV Development Programme

The goal of the Janssen HCV clinical development programme 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 express intent of targeting critical steps of the hepatitis C virus 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 approved by the U.S. Food & Drug Administration and, in May 2014, it was granted marketing authorisation by the European Commission. Subsequent marketing authorisations 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 authorisation held by Janssen-Cilag International NV.
