Home > Press > Arrowhead Receives Patent Allowance for DPC siRNA Delivery System with Peptide Backbone

Abstract:
Arrowhead Research Corporation (NASDAQ: ARWR), a targeted therapeutics company, today announced that it has received a Notice of Allowance from the U.S. Patent and Trademark Office for U.S. Patent Application Number 13/326,433 entitled, "Peptide-Based In Vivo siRNA Delivery System." The allowed claims specifically protect the use of targeted melittin or melittin-like peptides to facilitate delivery of siRNA conjugates to hepatocytes. This new patent protection covers the composition of the Dynamic Polyconjugate, or DPC, delivery system used in Arrowhead's RNAi-based drug candidate, ARC-520, against chronic hepatitis B virus infection.

Arrowhead Receives Patent Allowance for DPC siRNA Delivery System with Peptide Backbone

Pasadena, CA | Posted on May 7th, 2013

"We continue to expand the IP protection for multiple formulations of our DPC siRNA delivery system," said Dr. Chris Anzalone, President and CEO of Arrowhead. "This current allowance provides patent coverage through 2031 for our hepatitis B candidate, ARC-520, and other potential RNAi-based candidates using the same DPCs."
