Infergen is the brand name for consensus interferon. It is a totally artificial alfa interferon, and is

chemically different from the interferon in PegIntron and Pegasys. Infergen is not available yet as a

pegylated interferon, so it must be taken several times each week, preferably daily.

At AASLD 2007 the  results of the Direct trial were presented. This was a  medium sized study where

peginterferon nonresponders were given Infergen and ribavirin daily. Many of the patients had

stage 3 or 4 fibrosis. About ten  percent were sustained viral responders. We offer Infergen 15mcg

daily plus ribavirin to  nonresponders.
