About TMC435 clinical trial programs
TMC435 is a once daily protease inhibitor jointly developed by Medivir
and Tibotec Pharmaceuticals to treat hepatitis C virus
infections. TMC435 is currently being studied in three phase 2b clinical
trials (TMC435-C205, TMC435-C206 and TMC435-C215) in genotype 1 (G1)
treatment-naïve and in G1 patients that failed previous IFN-based
treatment. TMC435 is planned to enter phase 3 studies early 2011.

PILLAR Study (TMC435-C205)
TMC435-C205 is an ongoing randomized double-blind global phase 2b study
in 386 genotype-1 treatment-naïve patients. It evaluates once daily
treatment of TMC435 with different doses and durations given in addition
to standard of care treatment, consisting of ribavirin and
pegIFNalpha-2A.

ASPIRE Study (TMC435-C206)
TMC435-C206 is an ongoing randomized double-blind global phase 2b study
in 463 genotype-1 treatment-experienced patients. It evaluates once
daily treatment of TMC435 in with different doses of given in addition
to standard of care treatment, consisting of ribavirin and
pegIFNalpha-2A.

TMC435-C215
TMC435-C215 is an ongoing Japanese phase 2b study in 92 genotype-1
treatment-naïve patients. It evaluates once daily treatment of TMC435
with different doses and durations given in addition to standard of care
treatment, consisting of ribavirin and pegIFNalpha-2A. 

Opera-2 (TMC435-C202)
TMC435-C202 is a completed phase 2a study in treatment-naïve genotype 2
to 6 HCV patients. It is a once daily treatment of TMC435 during seven
days, at 200 mg. Subsequently, patients could continue with Standard of
Care treatment consisting of pegylated interferon and ribavirin upon
agreement with the study doctor.

About Hepatitis C
Hepatitis C is a blood-borne infectious disease of the liver and is a
leading cause of chronic liver disease and liver transplants. The WHO
estimates that nearly 180 million people worldwide, or approximately 3%
of the world's population, are infected with hepatitis C virus (HCV).
The CDC has reported that almost three million people in the United
States are chronically infected with HCV.
