Nanotechnology Holds Promise as Next Frontier in Vascular Intervention

Arrowhead Subsidiary Licenses Technology to Incorporate Carbon Nanotubes into Miniaturized Medical Devices for the Treatment of Cardiovascular Disease

PASADENA, CA and CHARLESTON, WV | Posted on August 3rd, 2007

Arrowhead Research Corporation (NASDAQ:ARWR) and Paragon Intellectual Properties, LCC announced today that Arrowhead's majority-owned subsidiary, Unidym Inc., has signed an exclusive license agreement with Paragon's majority-owned subsidiary, Nanotech Catheter Solutions, LLC (NCS). NCS will use Unidym's carbon nanotube technology in the development of medical devices for the treatment of cardiovascular disease. Under the terms of the agreement, Unidym will receive a 20 percent equity stake in NCS, and the parties will negotiate a supply agreement or royalty.

"We are pleased that our agreement with NCS could lead to improvements in technology to treat the millions of people around the world with cardiovascular disease," stated Art Swift, Unidym's CEO. "This agreement marks the launch of Unidym's licensing program. Our goal is to license our intellectual property and/or supply nanotubes to third parties commercializing products incorporating carbon nanotubes outside of our focus of electronics. We intend to replicate this model in other areas such as nanotube-based therapeutics, diagnostics, field emission displays, nonvolatile memory, and composite materials."

"We are thrilled about the opportunity to play a leading role in this exciting area of advanced technology," said Mark C. Bates, M.D., a leading interventional cardiologist and founder of the CAMC Vascular Center of Excellence in Charleston, West Virginia, and CEO of Paragon Intellectual Properties (the parent of NCS) and NCS. "We firmly believe that the application of nanotechnology to interventional devices such as catheters and stents could change the rules under which device designers operate, allowing them to implement improvements not previously deemed possible. This agreement with Unidym gives NCS critical intellectual property in this promising field."
