Boceprevir and treatment of chronic hepatitis C.

The addition of boceprevir to peginterferon and ribavirin has improved sustained response rates markedly. Boceprevir is effective in treatment naïve, relapsers, partial responders, and null responders. Those with advanced fibrosis require 44 weeks of boceprevir therapy after a 4-week peg/ribavirin lead-in. The main side effect with boceprevir is anemia and ribavirin dose reduction is an effective strategy. This review examines the current treatment paradigm of boceprevir-based treatment of chronic hepatitis C, examining treatment paradigms, predictors of response, futility rules, as well as preliminary results from studies examining boceprevir efficacy in additional populations. Further follow-up in these cohorts will be required.
