iTherX Initiates Phase 1b Study of First-in-Class Hepatitis C Virus Entry Inhibitor ITX-5061
SAN DIEGO, March 15, 2011 /PRNewswire/ -- iTherX, a pharmaceutical company dedicated to discovering and developing a new class of therapies for hepatitis C, today announced that it has commenced patient recruitment in an open-label, proof-of-concept Phase 1b study of its lead compound ITX-5061 in liver transplant patients with hepatitis C virus infection (HCV). ITX-5061 represents a first-in-class compound that inhibits entry of the hepatitis C virus into liver cells.
"ITX-5061 possesses a unique mechanism of action that prevents the hepatitis C virus from entering liver cells and has demonstrated potent preclinical antiviral activity against all HCV genotypes.In addition, it has already demonstrated safety in more than 280 subjects," said Jeffrey McKelvy, PhD, MD, President and Chief Executive Officer of iTherX. "We hope ITX-5061 will significantly improve long-term transplant outcomes."
The primary objective of the Phase 1b clinical trial will be to assess the safety and tolerability of ITX-5061 in liver transplant patients. The study will also assess HCV viral load for three months after liver transplantation to determine if ITX-5061 has any immediate and/or sustained impact on viral kinetics in treated patients. Approximately 20 patients will be enrolled into one of two cohorts: one group will receive supportive care only, while the second cohort will also receive ITX-5061 at a150 mg daily dose for seven days. The trial is being conducted at the University of Birmingham, UK under the direction of David Mutimer, MBBS, MD, FRACP, FRCP, Reader in Hepatology at Birmingham University and Consultant Hepatologist to the Birmingham QE Hospital Liver and Hepatobiliary Unit.
Preclinical studies have shown ITX-5061 to be a potent and selective inhibitor of HCV entry into hepatocytes, capable of preventing virus binding/fusion and cell to cell spread, suggesting ITX-5061 may reduce re-infection rates followi
