Viral Load, HIV Status, but not IL28B Predict Perinatal HCV Transmission

Women with higher HCV viral load and those coinfected with HIV were more likely to transmit HCV to their babies in a recent Spanish study. IL28B gene pattern did not affect transmission directly, but babies with the favorable CC pattern more often spontaneously cleared HCV.

BI 201335 for Hepatitis C Moves into Phase 3 Trials

Boehringer Ingelheim this week announced that enrollment has begun for a Phase 3 clinical trial of its experimental HCV NS3/4A protease inhibitor BI 201335.

FDA Hearings Next Week on Boceprevir and Telaprevir for HCV

FDA Antiviral Drugs Advisory Committee will hear evidence for boceprevir on April 27 and telaprevir on April 28.

EASL 2011: Boosted ABT-450 Improves Early Response to Interferon for Hepatitis C

Addition of the experimental HCV protease inhibitor ABT-450, boosted with ritonavir, to standard therapy increased the likelihood of complete early virological response at 12 weeks in previously untreated genotype 1 chronic hepatitis C patients.

Boosted Danoprevir Improves Response in Prior Null Responders

Nearly 90% of genotype 1b prior non-responder hepatitis C patients treated with ritonavir-boosted danoprevir plus pegylated interferon/ribavirin experienced early virological response at week 12, but breakthrough reached 50% for those with genotype 1a. alt

Idera Delays Study of TLR9 Agonist IMO-2125 for Hepatitis C

Idera Pharmaceuticals has decided to hold off on a planned clinical trial of its experimental hepatitis C drug IMO-2125, pending further toxicity data from ongoing animal studies.

EASL 2011: Monoclonal Antibody Bavituximab Well-Tolerated by HIV/HCV Coinfected People

An experimental monoclonal antibody that inhibits HCV replication was safe and well-tolerated in a clinical trial of HIV positive people coinfected with chronic hepatitis C, researchers reported at EASL 2011.

EASL 2011: Tegobuvir Works Well in Triple and Quad Regimens for HCV

Gilead's HCV polymerase inhibitor tegobuvir (GS-9190) improved response rates in treatment-naive genotype 1 patients when used in various combinations with pegylated interferon, ribavirin, and the experimental protease inhibitor GS-9256, researchers reported at EASL 2011.

EASL 2011: Pegylated Interferon Lambda Boosts Response with Few Side Effects

Hepatitis C patients taking an experimental interferon formulation -- pegylated interferon lambda -- had higher rates of rapid and early virological response, with fewer flu-like symptoms and blood cell deficiencies, according to a report at EASL 2011.
