PASADENA, Calif.--(BUSINESS WIRE)--Arrowhead Research Corporation (NASDAQ: ARWR), a biopharmaceutical company developing targeted RNAi therapeutics, today announced that it submitted an Investigational New Drug (IND) application to the U.S. Food and Drug Administration for ARC-520, it’s drug candidate for the treatment of chronic hepatitis B virus (HBV) infection. Arrowhead plans to submit additional clinical trial authorization applications with regulatory authorities in various jurisdictions in Europe and Asia.
Pending national regulatory review and approval, Arrowhead intends to initiate two Phase 2b, multicenter, randomized, double-blind, placebo-controlled, multi-dose studies to determine the depth of hepatitis B surface antigen (HBsAg) reduction following ARC-520 injection in combination with entecavir or tenofovir in patients with chronic immune active HBV infection. The Heparc-2002 study is planned to include patients who are negative for hepatitis B e-antigen (HBeAg) at screening and the Heparc-2003 study is planned to include patients who are positive for HBeAg at screening. The primary objective is to evaluate the depth of HBsAg decline in response to multiple doses of ARC-520 compared to placebo in patients with chronic HBV infection as a measure of drug activity. Secondary objectives are to assess measures of safety and tolerability and to evaluate multi-dose pharmacokinetics of ARC-520 in patients with chronic HBV infection when co-administered with a fixed dose of entecavir or tenofovir, in addition to other exploratory safety and pharmacodynamic objectives.
“As with our recent application to begin a Phase 1 study with ARC-AAT, this IND represents achievement of a key 2014 goal,” said Arrowhead President and CEO, Dr. Christopher Anzalone. “We look forward to beginning multi-dose studies with ARC-520.”
About ARC-520
Arrowhead’s RNAi-based candidate ARC-520 is being investigated in the treatment of chronic HBV infection. The small interfering RNAs (siRNAs) in ARC-520 intervene at the mRNA level, upstream of the reverse transcription process where current standard of care nucleotide and nucleoside analogues act. Arrowhead is investigating ARC-520 specifically, to determine if it can be used to achieve a functional cure, which is an immune clearant state characterized by hepatitis B s-antigen negative serum with or without sero-conversion. Arrowhead has completed a Phase 1 single ascending dose study in normal volunteers and the company is conducting a single dose Phase 2a study in chronic HBV patients. Approximately 350-400 million people worldwide are chronically infected with the hepatitis B virus, which can lead to cirrhosis of the liver and is responsible for 80% of primary liver cancers globally.
