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.

TCAD therapy active and synergistic against drug resistant influenza virus strains

Adamas Pharmaceuticals, Inc., a privately held company, reported today on the publication of results from a preclinical study that demonstrated the synergistic effects of triple combination antiviral drug (TCAD) therapy against multiple strains of seasonal, pandemic, and avian influenza A (H1N1, H3N2 and H5N1) virus, including three strains of amantadine resistant pandemic H1N1 and two strains of oseltamivir resistant seasonal H1N1.

Two genetic alterations linked to benign enzyme condition keep hepatitis C patients anemia-free

Many people who undergo treatment for hepatitis C develop hemolytic anemia, a disorder that destroys red blood cells. In some cases, it is so severe they have to reduce their medication or stop therapy altogether. But now, scientists in Duke University's Institute for Genome Sciences & Policy have discovered two genetic alterations linked to a benign enzyme condition that keep some patients anemia-free.

Study shows antiviral drugs could offer protection against HIV, Ebola, herpes and hepatitis C

The development of antibiotics gave physicians seemingly miraculous weapons against infectious disease. Effective cures for terrible afflictions like pneumonia, syphilis and tuberculosis were suddenly at hand. Moreover, many of the drugs that made them possible were versatile enough to knock out a wide range of deadly bacterial threats.

Researchers identify antiviral small molecule that is effective against numerous viruses

Viruses are insidious creatures. They differ from each other in many ways, and they can mutate - at times seemingly at will, as with HIV - to resist a host of weapons fired at them. Complicating matters further is that new viruses are constantly emerging.

Conatus Pharmaceuticals initiates combination trial of CTS-1027 with pegylated interferon and ribavirin for HCV

Conatus Pharmaceuticals Inc. announced today the initiation of a Phase II clinical trial evaluating CTS-1027 in combination with pegylated interferon (Pegasys®) and ribavirin (Copegus®) in refractory HCV patients. Antiviral activity, safety and tolerability of the triple combination will be assessed after up to 48 weeks of therapy.

Dynavax Technologies to present data on its SD-101 Phase 1b trial for chronic HCV infection

Dynavax Technologies Corporation announced today data from two studies that differentiate SD-101 from standard-of-care as well as emerging treatments for chronic HCV infection. The findings of a Phase 1b clinical trial and an in vitro study of SD-101's mechanism of action show that the second-generation TLR9 agonist is well tolerated and safe and induces both IFN-lambda and IFN-alpha at concentrations producing antiviral activity. The data will be presented at the 45th Annual Meeting of the European Association for the Study of the Liver in Vienna, Austria in April 2010.

Institute of Medicine urges healthcare providers to take steps to battle hepatitis B and C

The Institute of Medicine, a branch of the US National Academy of Sciences, is urging healthcare providers to take steps to battle liver-damaging hepatitis B and C, which are often overlooked viruses.

Progress in Anadys Pharmaceuticals' Phase II study of ANA598 announced

Anadys Pharmaceuticals, Inc. today announced that ANA598 dosing has been completed in the first dose cohort, 200 mg bid, in an ongoing Phase II study of ANA598 in combination with pegylated interferon and ribavirin (SOC) in HCV patients.

Pharmasset commences PSI-7977 Phase 2a trial for HCV

Pharmasset, Inc. today announces the initiation of a 28-day Phase 2a study with PSI-7977, a chirally pure isomer form of PSI-7851, a nucleotide analog polymerase inhibitor in development for the treatment of chronic hepatitis C (HCV). The trial will evaluate various doses of PSI-7977 in combination with Pegasys (peginterferon alfa 2a) and Copegus (ribavirin) in patients with HCV genotype 1 who have not been treated previously.

Telaprevir effective in HCV patients

Decision Resources, one of the world's leading research and advisory firms for pharmaceutical and healthcare issues, finds that data from recent clinical trials suggest that Vertex/Johnson & Johnson/Mitsubishi Tanabe's telaprevir is efficacious in hepatitis C virus patients who have not responded to previous treatment with peg-IFN/ribavirin. In contrast, the efficacy of Merck's (formerly Schering-Plough) boceprevir in treatment nonresponders has yet to be proven.

U.S. gastroenterologists to treat hepatitis C patients with telaprevir

Decision Resources, one of the world's leading research and advisory firms for pharmaceutical and healthcare issues, finds that U.S. gastroenterologists will treat a larger proportion of treatment nonresponder hepatitis C patients with Vertex/Tibotec/Mitsubishi Tanabe's telaprevir than Merck's boceprevir.

Treatment for chronic hepatitis C with pegylated-interferon and ribavirin proves effective

The current standard treatment for chronic hepatitis C with pegylated-interferon (PEG-IFN) and ribavirin is effective in approximately 50%-60% of patients, so that a substantial proportion of patients remain unresponsive.

Studies show treatment success for chronic hepatitis C may be predicted by rapid virological response

The likelihood of treatment success of 48 wk peg-interferon (PEG-IFN) plus ribavirin (RBV) therapy for chronic hepatitis C may be predicted by viral kinetics on therapy. In particular, recent studies have shown that sustained virological response (SVR) can be predicted by a rapid virological response (RVR), and an early virological response (EVR).
