Title: A Phase 3 Safety and Efficacy Study of Boceprevir in Combination With Peginterferon Alfa-2a and Ribavirin in Subjects With Chronic Hepatitis C Genotype 1 Who Failed Prior Treatment With Peginterferon/Ribavirin
Brief Summary: Based on previous experience with peginterferon alfa-2b/ribavirin in combination with boceprevir, the combination with peginterferon alfa-

2a/ribavirin and boceprevir is expected to be safe and well tolerated. Given the wide utilization of both peginterferons and the clear benefit of the

addition of boceprevir to peginterferon alfa-2b/ribavirin, it is important to demonstrate the safety and efficacy of boceprevir in combination with

peginterferon alfa-2a/ribavirin.
