Published Studies Related to Ribavirin
The combination of MK-5172, peginterferon, and ribavirin is effective in
treatment-naive patients with hepatitis C virus genotype 1 infection without
without cirrhosis... CONCLUSIONS: Once-daily MK-5172 (100 mg) with PR for 24 or 48 weeks was highly

disease]. [Article in Chinese] 
with hand-foot-mouth disease (HFMD)... CONCLUSIONS: Ribavirin aerosol can be effectively and safely used for treating
Antiviral activity of danoprevir (ITMN-191/RG7227) in combination with pegylated interferon alpha-2a and ribavirin in patients with hepatitis C. [2011.08.15]
BACKGROUND: Current therapy options for patients with chronic hepatitis C virus (HCV) infection genotype 1 are effective in <50%. Danoprevir (ITMN-191/RG7227) is a potent, selective, and orally active inhibitor of the HCV NS3/4A serine protease... CONCLUSIONS: Our study showed substantial antiviral efficacy of danoprevir in combination with pegylated interferon alpha-2a and ribavirin. Exploration of the safety and antiviral efficacy of danoprevir in longer clinical studies is warranted.
High-dose pegylated interferon-alpha and ribavirin in nonresponder hepatitis C patients and relationship with IL-28B genotype (SYREN trial). [2011.07]
BACKGROUND & AIMS: In patients with chronic hepatitis C who failed to respond to standard therapy, high-dose pegylated interferon (IFN)-alpha and/or ribavirin could induce a stronger antiviral response and prevent treatment failure and HCV resistance when combined with direct-acting antivirals. The influence of genetic determinants in this context remains unknown... CONCLUSIONS: High-dose pegylated IFN-alpha with standard or high doses of ribavirin induces a potent antiviral response in a substantial number of patients who did not respond to standard therapy. The IL-28B genotype is an independent predictor of the antiviral response. High-dose pegylated IFN-alpha in combination with ribavirin and protease inhibitors appears as an attractive option for future study in this population. Copyright (c) 2011 AGA Institute.

Twice-weekly pegylated interferon-alpha-2a and ribavirin results in superior viral kinetics in HIV/hepatitis C virus co-infected patients compared to standard therapy. [2011.06.01]
CONCLUSION: Our results, when confirmed in larger randomized clinical trials, may provide a novel therapeutic approach to improve SVR among HIV/HCV co-infected patients, especially African-American patients.

Infergen and Ribavirin Treatment of Patients With HCV Who Achieved Partial Response to Peginterferon-Alfa and Ribavirin [Active, not recruiting]
This is a 60-to-72 week multicenter study to evaluate Infergen and Ribavirin in patients with
Chronic Hepatitis C Virus after partial response to treatment using peginterferon-alfa and
Ribavirin therapy. The study will be conducted at approximately 50 sites across the United
PEG-Interferon a-2b + Ribavirin for Treatment of Patients With Chronic Hepatitis C Who Have Previously Failed to Achieve a Sustained Virologic Response Following Interferon Alfa or Interferon a-2b + Ribavirin Therapy [Completed]
HRN-003 STUDY SYNOPSIS
OBJECTIVE: To compare the Sustained Virologic Response (SVR) of PEGIntron plus ribavirin
among patients receiving a fixed dose of PEGIntron versus weighted-adjusted dosing.
OVERVIEW OF STUDY DESIGN: This is a multi-center, randomized, open-label clinical trial using
PEGIntron weight-adjusted dose by subcutaneous injection weekly + ribavirin by mouth twice
daily for 48 weeks OR PEGIntron fixed dose by subcutaneous injection weekly + ribavirin by
mouth twice daily for 48 weeks.
STUDY POPULATION: 600 Adult patients with chronic hepatitis C virus infection who have
previously failed to achieve a sustained virologic response following interferon alfa or
interferon alfa-2b plus ribavirin therapy.
DOSAGE AND ADMINISTRATION: Eligible participants will be randomized to receive PEGIntron
weight-adjusted dose (1. 5 mg/kg) by subcutaneous injection weekly + ribavirin 400 mg by mouth
twice daily for 48 weeks OR PEGIntron fixed dose (150 mg if weight > than 80 kg or 100 mg if
weight < 80 KG) by subcutaneous injection weekly + ribavirin 400 mg by mouth twice daily for
EFFICACY EVALUATIONS: Laboratory analysis, quality of life assessments, and change in study
medication doses will be obtained.
SAFETY EVALUATIONS: Assessment of laboratory evaluations, vital signs, incidence and severity
of adverse experiences and progression of disease, as measured by HCV viral load.
This is a treatment protocol to evaluate the antiviral efficacy, safety and tolerability
polyethylene glycol (PEG) conjugated interferon alfa-2b (PEGIntron) for the treatment of
chronic hepatitis C virus infection in patients who have previously failed to achieve a
sustained virologic response following interferon alfa or interferon alfa-2b plus ribavirin
therapy. Patients will be stratified according to their response to the previous course of
therapy (i. e. non-reponse or relapse virologic pattern
This is a multi-center, randomized, open-label clinical trial that will involve approximately
25 sites with an anticipated enrollment of 600 patients over a six-month period.
Eligible participants will be randomized to receive PEGIntron weight-adjusted dose (1. 5
mg/kg) by subcutaneous injection weekly + ribavirin 400 mg by mouth twice daily for 48 weeks
OR PEGIntron fixed dose (150 mg if weight > than 80 kg or 100 mg if weight < 80 KG) by
subcutaneous injection weekly + ribavirin 400 mg by mouth twice daily for 48 weeks.
- Group A: PEGIntron weight -adjusted dose (1. 5 mg/kg) by subcutaneous injection weekly
+ ribavirin 400 mg by mouth twice daily for 48 weeks (Total therapy x 48weeks).
- Group B: PEGIntron fixed dose (150 mg if weight > than 80 kg or 100 mg if weight < 80
KG) by subcutaneous injection weekly + ribavirin 400 mg by mouth twice daily for an
additional 48 weeks (Total therapy x 48 weeks).
Trial of Peg-Interferon Plus Epoetin-Alfa for Treatment of Chronic Hepatitis C Virus Infection [Completed]
The purpose of this study is to determine if the use of epoetin-alpha will allow patients
with chronic hepatitis C virus infection to be treated with higher doses of
peginterferon-alpha-2b and ribavirin, thus increasing chances at lower viral levels and
raising sustained virologic response.
REPEAT Study - A Study of PEGASYS (Peginterferon Alfa-2a (40KD)) Therapy in Combination With COPEGUS (Ribavirin) in Patients With Chronic Hepatitis C (CHC) Who Did Not Respond to Previous PegIntron (Peginterferon Alfa-2b (12KD))/Ribavirin Combination Therapy [Completed]
This 4 arm study is designed for patients with CHC who have not responded to peginterferon
alfa-2b (12KD)/ribavirin combination therapy. In these patients, the effects of lengthening
the duration of treatment, as well as including an initial 12-week period of high-dose
PEGASYS (360 micrograms sc), are compared with the standard combination therapy of PEGASYS
(180 micrograms sc) and ribavirin (1000-1200mg po). The anticipated time on study treatment
is 1-2 years and the target sample size is 500+ individuals.
Triple Therapy With Peg-Interferon Alfa-2b/Ribavirin Plus Amantadine Compared to Standard Peg-Interferon Alfa-2b/Ribavirin for Previous Hepatitis C Virus (HCV) Non Responders [Terminated]
Triple antiviral therapy with peg-interferon-alfa/ribavirin+amantadine was suggested to
increase sustained virological response (SVR) rates in HCV non-responders to a standard
Patients with hepatitis C virus infection were eligible if they had failed to respond to a
single previous 24 week cycle of interferon/ribavirin combination therapy. Non-response was
defined as persistent HCV RNA in the serum during the last month of treatment.
This study tested the efficacy and safety of pegylated interferon alfa-2b with ribavirin and
amantadine or a placebo for 48 weeks.
