Ribavirin News and Research

RSS

Ribavirin, also known as Copegus, Rebetol, Virazole, or a component of Rebetron, is a type of antiviral medicine called a nucleoside analogue. This medicine blocks the ability of the hepatitis C virus (HCV) to make more copies of itself. Ribavirin is not active against HIV. Ribavirin is used in combination with interferon alfa-2a or -2b or peginterferon alfa-2a or -2b to treat HIV infected patients who are also infected with HCV.

Interferon as long-term treatment for hepatitis C not effective

Use of the drug interferon as a long-term maintenance strategy to slow the progression of liver disease associated with the hepatitis C virus is ineffective, UT Southwestern Medical Center researchers and their colleagues from nine other institutions have found in a multicenter study.

Low-dose peginterferon used for hepatitis C doesn't work

An NIH funded multi-center clinical trial found no benefit from "maintenance therapy," low-dose peginterferon used for hepatitis C patients who have not responded to an initial round of treatment.

Anadys Pharmaceuticals receives fast track for ANA598 treatment of chronic hepatitis C virus

Anadys Pharmaceuticals, Inc. has announced that the U.S. Food and Drug Administration (FDA) has granted fast track designation to ANA598 for the treatment of chronic hepatitis C virus (HCV) infection. ANA598 is Anadys' investigational hepatitis C non-nucleoside polymerase inhibitor.

Researchers develop new strategy for broad spectrum anti-viral drugs

Bavituximab, an anti-viral drug developed by UT Southwestern Medical Center researchers, shows promise as a new strategy to fight viral diseases, including potential bioterrorism agents.

Tibotec presents interim findings for TMC435, investigational hepatitis C treatment

New clinical data show antiviral activity of TMC435, an investigational protease inhibitor (PI) being developed by Tibotec BVBA for the treatment of chronic hepatitis C virus (HCV) infection.

GSK to acquire Genelabs Technologies

GlaxoSmithKline and Genelabs Technologies, Inc announced today that they have entered into a definitive agreement pursuant to which GSK will acquire Genelabs for approximately $57 million (pounds Sterling 35 million) through a tender offer of $1.30 per share in cash. This strategic acquisition will strengthen GSK's effort to develop and deliver novel therapies against the hepatitis C virus (HCV).

Anti-itching drug clemizole shows promise against hepatitis C

The fight against the liver disease hepatitis C has been at something of an impasse for years, with more than 150 million people currently infected, and traditional antiviral treatments causing nasty side effects and often falling short of a cure. Using a novel technique, medical and engineering researchers at Stanford University have discovered a vulnerable step in the virus' reproduction process that in lab testing could be effectively targeted with an obsolete antihistamine.

New studies examine use of the nucleoside polymerase inhibitor, R1626, to the standard therapy for hepatitis C

Two new studies examine the use of the nucleoside polymerase inhibitor, R1626, to the standard therapy for hepatitis C. The reports appear in the August issue of Hepatology, a journal published by John Wiley & Sons on behalf of the American Association for the Study of Liver Diseases (AASLD).

Hepatitis C therapy peginterferon alfa-2b shows promise

The hepatitis C therapy peginterferon alfa-2b, when given as low-dose maintenance therapy, can prevent disease progression in certain patients who failed previous interferon-based hepatitis C therapies and have advanced liver disease, according to findings from a large, four-year study presented today at the 43rd annual meeting of the European Association for the Study of the Liver (EASL).

Risk factors for severe RSV infection in immunocompromised children

St. Jude Children's Research Hospital investigators and collaborators have shown how to predict if a child who is infected with respiratory syncytial virus (RSV) while being treated for cancer or another catastrophic disease is at high risk for developing severe infection. The finding will help clinicians improve guidelines for managing these infected children.

Shorter HCV treatment shows notable success

Two new randomized controlled trials show that treating Hepatitis C (HCV) with peginterferon and ribavirin for shorter durations can yield success rates similar to those from longer treatment lengths, with cost-savings and lower risk of serious side effects.

Optimal therapy for U.S. hepatitis C patients

As reported recently in the journal Hepatology, WIN-R, a multicenter study of over 5,000 patients with hepatitis C virus (HCV) showed treatment with weight-based REBETOL ribavirin, USP) (RBV) in combination with pegylated interferon (PEG-IFN) alfa-2b achieved significantly higher rates of sustained virologic response (SVR) and lower relapse rates compared to combination therapy using a flat dose of RBV 800 mg/day. Superior response was found particularly in patients with the most difficult-to-treat form of the disease, genotype 1 HCV. Efficacy was consistent across all weight groups.

Hepatitis C treatment reduces the virus but serious liver problems may progress

Patients with chronic hepatitis C and advanced liver disease who did not respond to previous standard therapy experienced significant decreases in their liver enzymes, viral levels, and liver inflammation following treatment with long-term pegylated interferon.

New mechanism discovered that mammalian cells employ to fight infections of the Hepatitis C virus

A team of researchers led by biologists at the University of California, San Diego has discovered a completely new mechanism that mammalian cells employ to fight infections of the Hepatitis C virus, which affects approximately 2.7 million Americans and 170 million people worldwide.
