INGELHEIM, Germany - Friday, October 21st 2011 [ME NewsWire]
(BUSINESS WIRE)-- For Non-US Media Only
Boehringer Ingelheim announced today that new data from its hepatitis C virus (HCV) portfolio will be presented in scientific sessions at The Liver Meeting® 2011, the 62nd Annual Meeting of the American Association for the Study of Liver Diseases (AASLD), taking place November 4 – November 8 in San Francisco, CA. The abstracts are published online at www.aasld.org.
Key data presented will include a week 12 interim analysis of SOUND-C2, a Phase IIb study evaluating an interferon-free combination of its protease inhibitor BI 201335 and its polymerase inhibitor BI 207127 – with and without ribavirin in treatment-naïve HCV infected patients.1 In addition, SILEN-C1 and SILEN-C3 data will further assess the efficacy and safety of BI 201335 in treatment-naïve HCV-infected patients, in combination with pegylated interferon alfa-2a and ribavirin (PegIFN/RBV).2,3
SOUND-C2 In SOUND-C2, 362 treatment-naïve patients with chronic genotype-1 HCV infections were randomised into five interferon-free treatment arms, each with 120mg BI 201335 once daily (QD) but with different dosings of BI 207127 and ribavirin as follows:
120 mg QD BI 201335 combined with 600 mg TID (thrice daily) BI 207127 and RBV for 16 weeks
120 mg QD BI 201335 combined with 600 mg TID BI 207127 and RBV for 28 weeks
120 mg QD BI 201335 combined with 600 mg TID BI 207127 and RBV for 40 weeks
120 mg QD BI 201335 combined with 600 mg BID (twice daily) BI 207127 and RBV for 28 weeks
120 mg QD BI 201335 combined with 600 mg TID BI 207127 for 28 weeks (no RBV)
The interim results will provide early virological response rates for all treatment arms of the novel interferon-free combination of BI 201335/BI 207127/ribavirin and are due to be presented by Stefan Zeuzem, M.D., Chief of the Department of Medicine and Professor of Medicine at the Johann Wolfgang Goethe University Hospital in Frankfurt, Germany and lead investigator of the study.
SILEN-C1 In SILEN-C1, 429 treatment-naïve patients with chronic genotype-1 HCV infections were randomised to the following treatment groups:
Placebo
BI 201335 120 mg QD with 3 days lead-in (LI) of PegIFN/RBV
BI 201335 240 mg QD/LI
BI 201335 240 mg QD without LI
In each arm, BI 201335 or placebo were given for 24 weeks together with PegIFN/RBV for 24 or 48 weeks. Results presented at AASLD will include an analysis of sustained virological response across different baseline factors, including difficult to treat HCV cases.
SILEN-C3 In SILEN-C3, 159 treatment-naïve genotype-1 patients were randomised to the following treatment groups:
BI 201335 120mg QD for 12 weeks with 3 days lead-in of PegIFN/RBV
BI 201335 120mg QD for 24 weeks with 3 days lead-in of PegIFN/RBV
In each arm, PegIFN/RBV was given for 24 or 48 weeks. Results presented at AASLD will provide an analysis of 12 versus 24 weeks of treatment with BI 201335.
Titles for accepted abstracts are below and full results and conclusions for these abstracts will be shared at AASLD at the times specified.
