High dose consensus interferon in nonresponders to interferon alpha-2b and ribavirin with chronic hepatitis C (Part 2)

Consensus IFN (CIFN) is a genetically engineered molecule derived by aligning the sequences of all known alpha IFN s and assigning the most commonly observed amino acid in each sequence. Studies have shown that treatment of naive subjects with HCV infection with 9 |ag CIFN gives a sustained virological response similar to that of standard IFN alpha-2b, but the former is more effective in those with a high viral load and/or with genotype 1 infection (15 |ag CIFN is equivalent to 3.75 MIU IFN alpha-2b). Retreatment with CIFN for 12 months has been shown to be effective in achieving a sustained response of 58% in relapsers to previous IFN alpha-2b or CIFN given for six months and 13% in nonresponders to six months of prior IFN monotherapy when given for 12 months.

The purpose of the present study was to evaluate the efficacy of high dose CIFN (15 |ag daily) induction therapy given for 12 weeks followed by CIFN (15 |ag) three times per week for a further 3 6 weeks in patients with chronic HCV infection who were nonresponders to previous therapy with a complete course of IFN alpha-2b and ribavirin (ie, those who had received greater than 80% of the recommended IFN alpha-2b and greater than 80% of the recommended dose of ribavirin for their body weight for 80% of the recommended duration of therapy). It was hypothesized that CIFN given in a daily dose would be able to achieve a greater antiviral effect by achieving higher serum concentrations, allowing for less chance of viral breakthrough and development of viral resistance during therapy.
