TITUSVILLE, N.J., Nov. 1, 2012

TITUSVILLE, N.J., Nov. 1, 2012 /PRNewswire/ --Janssen Pharmaceuticals, Inc.
today announced that it has entered into a non-exclusive collaboration with
Vertex Pharmaceuticals Incorporated to evaluate in a Phase 2 study the safety
and efficacy of an all-oral regimen for the treatment of hepatitis C (HCV).
The regimen will include Janssen's investigational protease inhibitor
simeprevir (TMC435) and Vertex's investigational nucleotide analogue HCV
polymerase inhibitor VX-135. As a first step, Janssen will conduct a drug-drug
interaction (DDI) study with simeprevir and VX-135. The DDI study will support
the initiation of the Phase 2 study in early 2013 pending discussions with
regulatory authorities.

The goal of the Phase 2 study will be to evaluate the safety, tolerability and
viral cure rates of a 12-week regimen of simeprevir and VX-135, administered
with and without ribavirin, in treatment-naive patients who have chronic
non-cirrhotic genotype 1 HCV. The companies will jointly fund development
costs associated with the collaboration. There are no up-front or milestone
payments associated with the agreement.

Simeprevir is an investigational NS3/4A protease inhibitor currently in Phase
3 trials, developed in collaboration with and licensed from Medivir AB. VX-135
is an investigational uridine nucleotide analogue pro-drug designed to inhibit
the replication of HCV by acting on the NS5B polymerase.

"There is a significant unmet need for all-oral treatment regimens for people
living with hepatitis C," said Wim Parys, Global Head of Infectious Diseases
at Janssen. "Janssen's collaboration with Vertex underscores our commitment to
better understand the potential utility of simeprevir in a number of different
interferon-free treatment combinations and HCV patient populations."

About Simeprevir
Simeprevir (TMC435) is an NS3/4A protease inhibitor jointly developed by
Janssen and Medivir AB to treat chronic HCV infection. Simeprevir is being
studied in combination with pegylated interferon and ribavirin, and in
combination with direct-acting antiviral (DAA) agents in all-oral
interferon-free regimens, with and without ribavirin.

Global Phase 3 studies of simeprevir include QUEST-1 and QUEST-2 in
treatment-naive patients, PROMISE in patients who have relapsed after prior
interferon-based treatment and ATTAIN in treatment-experienced patients. In
parallel to these trials, Phase 3 studies for simeprevir are ongoing in both
treatment-naive and treatment-experienced HIV-HCV co-infected patients, HCV
genotype 4 patients and in Japanese HCV genotype 1 patients.

Simeprevir is also being studied in other Phase 2 interferon-free trials, with
and without ribavirin, in combination with:

  oJanssen's TMC647055 and ritonavir in treatment-naive, relapser or
    null-responder HCV genotype 1 patients;
  oGilead Sciences, Inc.'s sofosbuvir (GS-7977) in null-responder HCV
    genotype 1 patients; and
  oBristol-Myers Squibb's daclatasvir (BMS-790052) in treatment-naive or
    previous null-responder HCV genotype 1 patients.

About Hepatitis C
Hepatitis C, a blood-borne infectious disease of the liver and a leading cause
of chronic liver disease and liver transplants, is a rapidly evolving
treatment area with a clear need for innovative treatments. Approximately 170
to 210 million people are infected with hepatitis C worldwide, with three to
four million people newly infected each year.
