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.
Ribavirin for patients with Crimean-Congo haemorrhagic fever: a systematic review and meta-analysis. [2011.06]
BACKGROUND: Crimean-Congo haemorrhagic fever (CCHF) is a potentially fatal tick-borne infection. The virus is widely distributed around the world and reports of sporadic cases and outbreaks have recently increased significantly. Some authors have proposed that ribavirin improves survival in CCHF and this view appears to be widely accepted... CONCLUSIONS: Our systematic review and meta-analysis revealed that the available data in the literature are inadequate to support a claim of efficacy of ribavirin in CCHF. We believe a real uncertainty exists over the benefit of ribavirin in the treatment of CCHF, which necessitates the urgent conduct of a randomized placebo-controlled trial.
Coffee consumption is associated with response to peginterferon and ribavirin therapy in patients with chronic hepatitis C. [2011.06]
BACKGROUND & AIMS: High-level coffee consumption has been associated with reduced progression of pre-existing liver diseases and lower risk of hepatocellular carcinoma. However, its relationship with therapy for hepatitis C virus infection has not been evaluated... CONCLUSIONS: High-level consumption of coffee (more than 3 cups per day) is an independent predictor of improved virologic response to peginterferon plus ribavirin in patients with hepatitis C.

This 2 arm study will compare the efficacy and safety of treatment with Pegasys (180
micrograms sc weekly) plus Copegus (800mg po daily) and PEGASYS (180 micrograms sc weekly)
plus Copegus (1000-1200mg po daily) in interferon-naive patients with CHC genotype 1
co-infected with HIV-1. Treatment will be administered for 48 weeks, and this will be
followed by 24 treatment-free weeks. The anticipated time on study treatment is 3-12 months,
and the target sample size is 100-500 individuals.
A Study of HCV Polymerase Inhibitor Pro-Drug in Combination With PEGASYS Plus COPEGUS Compared With PEGASYS Plus COPEGUS in Patients With Chronic Hepatitis C Genotype 1 Infection. [Active, not recruiting]
This 7 arm study will determine the optimal treatment combination, based on efficacy and
safety. Patients with chronic hepatitis C (CHC), genotype 1, will be randomized to one of 7
treatment groups. Groups 1, 2, 4, 5 and 6 will receive triple combination treatment with HCV
polymerase inhibitor pro-drug (at doses of 500, 1000 or 1500mg po bid) plus PEGASYS (90 or

PEGASYS 180 micrograms sc weekly plus Copegus 1000/1200mg po qd for 24 weeks; after 24 weeks,
those achieving a rapid virological response (RVR) will stop all medication, and non-RVR
patients will remain on triple combination for an additional 24 weeks. Group 7 will receive
SOC for 48 weeks. There will be a 24 week period of treatment-free follow-up for all
treatment groups. The anticipated time on study treatment is 3-12 months, and the target

Ribavirin for Hemorrhagic Fever With Renal Syndrome in Germany [Not yet recruiting]
This is a treatment protocol using IND Ribavirin-there is no control group. Hemorrhagic
Fever with Renal Syndrome (HFRS) is caused by a virus acquired by contact with chronically
infected rodent hosts. HFRS is present throughout Europe and caused mainly by Puumala and
Dobrava viruses. Treatment consists mainly of supportive care with careful attention to
control of blood pressure and fluid balance and/or dialysis. Early initiation of IND
Intravenous Ribavirin has been shown to be an effective treatment for HFRS and may prevent
the need for dialysis. It is important to initiate therapy based on a diagnosis consistent
with HFRS and a history that makes exposure likely. This study will monitor the clinical
events that occur with HFRS as well as the safety and efficacy of Ribavirin.
