Subcutaneous Continuous Infusion of Interferon Alfa-2b and Ribavirin in Hepatitis C Genotype 1 Nonresponders

Summary

For chronic hepatitis C patients unresponsive to previous (PEG-)IFN/RBV combination therapy we propose continuous subcutaneous administration of high-dose IFN-a2b (Intron A®) for 48 weeks in combination with 15 mg/kg/day RBV (Rebetol®) and optimal management of side effects in order to maintain the highest possible dosages of both IFN-a2b and RBV for 48 weeks. We expect improved tolerability with continuous subcutaneous pump delivery of IFN-a2b compared to thrice weekly or daily subcutaneous injection of IFN-a2b, and increased antiviral activity and biologic potency due to sustained and higher levels of a fully potent interferon protein.
