Arrowhead Research Corporation (NASDAQ: ARWR), a targeted therapeutics company, announced today that prominent hepatologist Robert G. Gish, MD, will serve as Chairman of the company’s newly created hepatitis B Clinical Advisory Board. In this leadership role, Dr. Gish will assist with recruitment of additional advisory board members and will advise the company on clinical and regulatory approval strategy in addition to analysis, and interpretation of clinical trial results for the HBV program and its associated lead candidate, ARC-520. “Hepatitis B is a global problem that needs more effective treatment options,” said Dr. Gish. “Arrowhead’s clinical candidate, ARC-520 is a unique and potentially powerful approach to treating HBV and I’m excited to have the opportunity to contribute to this clinical program.” “Dr. Gish’s international expertise in hepatitis B and his guidance on clinical trials both in the U.S. and in Asia are important to Arrowhead,” said Dr. Chris Anzalone, President and CEO of Arrowhead. “We are honored to have somebody of his caliber chair our Clinical Advisory Board.” Dr. Gish joined the full time faculty at University of California, San Diego in December 2010 as Clinical Professor, Section Chief of Hepatology, and Medical Director for the Center of Excellence for Hepatobiliary Disease and Abdominal Transplantation (CHAT). Since that date, research efforts have expanded to include Point of Care testing, public policy for viral hepatitis, collaboration with co-investigators to study NASH, metabolism of intralipid infusions and clinical trials for HCV and HBV. He was the Co-Medical Director at the California Pacific Medical Center in San Francisco and became the Medical Director of the Liver Transplant Program in 1995. He was a faculty member at the University of California, Davis from 1991-1994 and was also part of the faculty at the Merced Family Practice Program (UCD affiliate) from 1991 to 1999.
