Efficacy and Safety Study of PEG-rIL-29 Plus Ribavirin to Treat Chronic Hepatitis C Virus Infection

2014-07-23 21:12:18 | BioPortfolio

Summary

Interleukin 29 (IL-29) is a substance that is produced in the body to help fight viral infections. The purpose of this study is to evaluate the safety and antiviral effects of several different doses of PEG-rIL-29 (a man-made form of IL-29) when it is given in combination with daily oral doses of ribavirin (an antiviral drug) to subjects with hepatitis C infection who have received no prior treatment for this disease.

Description

PEG-rIL-29 (also known as PEG-interferon lambda) is a unique Type III interferon molecule that has demonstrated antiviral activity when administered weekly for 4 weeks to treatment-relapsed and treatment-naive subjects with genotype 1 hepatitis C virus (HCV) infection. Because PEG-rIL-29 binds to a unique receptor with a more limited distribution than the receptor for interferon (IFN)-α, it may have the potential to treat HCV without some of the treatment-limiting side effects associated with IFN-α-based therapies. The purpose of this Phase 2a/b randomized, controlled, multicenter study is to compare the safety and efficacy of PEG-rIL-29 and peginterferon alfa-2a, both administered subcutaneously weekly for up to 48 weeks in combination with daily oral ribavirin, in treatment-naive subjects with chronic genotype 1, 2, 3, or 4 HCV infection. The initial part of the study (Phase 2a) will be conducted as an open-label study; the second part of the study (Phase 2b) will be conducted as a blinded study. The updated information provided in this listing is specific to the Phase 2b portion of the study.

No association between IFNL3 (IL28B) genotype and response to peginterferon alfa-2a in HBeAg-positive or -negative chronic hepatitis B.

It has yet to be firmly established whether host IFNL3 (IL28B) genotype influences interferon responsiveness in patients with chronic hepatitis B. We investigated associations between single-nucleotid...

Ribavirin therapy of hepatitis E infection may cause hyporegenerative anemia in pediatric renal transplant patients.

HEV infection can lead to chronic hepatitis in immunosuppressed patients; extrahepatic manifestations are rarely seen. Here, we report a 13-year-old renal transplant patient with chronic hepatitis E a...

An easy-to-use baseline scoring system to predict response to peginterferon alfa-2a in patients with chronic hepatitis B in resource-limited settings.

Approximately one-third of patients have durable responses after finite (48-week) treatment with peginterferon alfa-2a. The ability to identify patients likely to respond would be particularly useful ...

In the past few years, a growing body of clinical evidence has highlighted the risk of vitamin D deficiency in patients with chronic hepatitis C and that vitamin D levels are associated with the cours...

Zinc: A Potential Antiviral Against Hepatitis E Virus Infection?

Hepatitis E virus (HEV) is a major cause of viral hepatitis worldwide. Owing to its feco oral transmission route, sporadic as well as epidemic outbreaks recurrently occur. No specific antiviral therap...

Medical and Biotech [MESH] Definitions

A family of hepatotropic DNA viruses which contains double-stranded DNA genomes and causes hepatitis in humans and animals. There are two genera: AVIHEPADNAVIRUS and ORTHOHEPADNAVIRUS. Hepadnaviruses include HEPATITIS B VIRUS, duck hepatitis B virus (HEPATITIS B VIRUS, DUCK), heron hepatitis B virus, ground squirrel hepatitis virus, and woodchuck hepatitis B virus (HEPATITIS B VIRUS, WOODCHUCK).

INFLAMMATION of the LIVER in humans caused by HEPATITIS DELTA VIRUS, a defective RNA virus that can only infect HEPATITIS B patients. For its viral coating, hepatitis delta virus requires the HEPATITIS B SURFACE ANTIGENS produced by these patients. Hepatitis D can occur either concomitantly with (coinfection) or subsequent to (superinfection) hepatitis B infection. Similar to hepatitis B, it is primarily transmitted by parenteral exposure, such as transfusion of contaminated blood or blood products, but can also be transmitted via sexual or intimate personal contact.

INFLAMMATION of the LIVER in humans caused by HEPATITIS DELTA VIRUS in conjunction with HEPATITIS B VIRUS and lasting six months or more.

INFLAMMATION of the LIVER in humans caused by HEPATITIS C VIRUS, a single-stranded RNA virus. Its incubation period is 30-90 days. Hepatitis C is transmitted primarily by contaminated blood parenterally, and is often associated with transfusion and intravenous drug abuse. However, in a significant number of cases, the source of hepatitis C infection is unknown.

INFLAMMATION of the LIVER in humans that is caused by HEPATITIS C VIRUS lasting six months or more. Chronic hepatitis C can lead to LIVER CIRRHOSIS.
