Purpose

A Phase II, Open Label, Multi-Center, Proof-Of-Concept Study determing whether treatment with HDV-Interferon (HDV-IFN), by oral or subcutaneous (injection) routes, and ribavirin results in similar efficacy [Rapid Virologic Response (RVR)] and safety as the reported efficacy and safety with pegylated alpha-interferon-2a and ribavirin (historical control) in patients with chronic hepatitis C (treatment naïve by oral route and non-responders by SC route respectively).

Estimated Study Completion Date:	December 2009
Estimated Primary Completion Date:	December 2009 (Final data collection date for primary outcome measure)

Arms	Assigned Interventions
Experimental: 1 Oral HDV-Interferon	Drug: Oral HDV-Interferon + ribavarin Naive pateints
Experimental: 2 Injectable HDV-Interferon + ribavarin	Drug: Injectable HDV-Interferon + ribavarin Nonresponders

Detailed Description:

Part 1 ("initial part") - 4 weeks of treatment (28 days):

All patients will complete an initial 4 weeks of treatment with HDV-Interferon (HDV-IFN) (treatment naïve by oral route and non-responders by SC route respectively) and ribavirin.
The Part 1 of the study shall assess whether a 4-week treatment course with HDV-Interferon (HDV-IFN), orally or by subcutaneous injection, and ribavirin results similar efficacy [Rapid Virologic Response (RVR)] and safety as the reported efficacy and safety with pegylated alpha-interferon-2a and ribavirin (historical control) in patients with chronic hepatitis C (treatment naïve and non-responders).

Part 2 ("continuation part") - 44 or 20 weeks of treatment + 24 weeks (follow-up period):

Patients with hepatitis C viral genotype 1, who achieve RVR, will be treated for another 44 weeks of therapy (to complete 48 weeks of active treatment) followed by 24 weeks of treatment-free follow-up period.
Patients with hepatitis C viral genotype 3, who achieve RVR, will be treated for another 20 weeks of therapy (to complete 24 weeks of active treatment) followed by 24 weeks of treatment-free follow-up period.
Follow-up period (24 weeks): Thus, in addition to treatment in Part 1 of study, each completed patient with viral genotype 1 will receive 44 weeks of therapy and 24 weeks of treatment-free follow-up; and viral genotype 3 patients will have 20 weeks of therapy & 24 weeks of treatment study drug free follow-up.
Overall study duration (72 or 48 weeks): Patients with viral genotype 1 will have an overall study duration of 72 weeks (48 weeks of therapy plus 24 weeks follow-up) and patients with viral genotype 3 will have an overall study duration of 48 weeks (24 weeks of therapy plus 24 weeks follow-up).
