General information about the trial
|
|||
Main objective of the trial |
This study was done to find out if the addition of boceprevir to standard of care (SOC) treatment with peginterferon alfa-2b (PegIFN-2b) + ribavirin (RBV) is effective for participants with chronic hepatitis C (CHC) genotype 1 and cirrhosis who were not successfully treated by previous SOC. All participants were to receive treatment with SOC alone for 4 weeks and then boceprevir was to be added to the treatment regimen for 44 additional weeks of combined treatment.
|
||
Protection of trial subjects |
This study was conducted in conformance with Good Clinical Practice standards and applicable country and/or local statutes and regulations regarding ethical committee review, informed consent, and the protection of human subjects participating in biomedical research. The following additional measure defined for this individual study was in place for the protection of trial participants: A participant was to be discontinued from all study therapy if they met the per-protocol criteria for virologic failure.
