Abstract:
Arrowhead Research Corporation (NASDAQ: ARWR) announced today that it has
formed a new wholly-owned subsidiary and has agreed to acquire the assets, as
well as the name, of C Sixty, Inc. (C-60), a company pioneering the development
of new drugs based on buckministerfullerenes (also known as fullerenes or
buckyballs).

Arrowhead to form new nanomedicine subsidiary and acquire nanotherapeutics company, C Sixty, Inc.

The new subsidary joins Arrowhead as its third focused on
nanomedicine. Arrowhead operates two other majority owned
subsidiaries commercializing nanotherapeutics. Calando
Pharmaceuticals is a leading RNAi company specializing in the design
and delivery of siRNA therapeutics. Insert Therapeutics is
commercializing drug-delivery-enhanced small-molecule therapeutics
and nucleic acids. Insert's first anti-cancer drug candidate is in
Phase I clinical trials.

"The future of medicine lies in targeted delivery of therapeutics
through nanotechnology," said R. Bruce Stewart, Arrowhead's Chairman.
"Our experience and expertise in this area makes C-60 a great
strategic complement to our other majority owned subsidiaries."

Fullerenes are a highly structured, water soluble, nanoscale form of
carbon, similar to carbon nanotubes, discovered by Richard Smalley,
who received the Nobel Prize for his work in this area. Roughly one
nanometer in diameter, the molecules are composed of 60 carbon atoms
and have the symmetry of soccer balls. The spherical shape, hollow
interior, and 60 carbon atoms of the molecule allow drug designers
the opportunity to attach therapeutic and targeting chemical groups
in many configurations.

C Sixty, Inc. has secured and developed a strong patent position
covering the strategic biomedical uses of fullerenes. Initially, C-60
will focus on the antioxidant activity of fullerenes. Arrowhead
believes that drugs based on fullerene antioxidant molecules may have
significant impact on several unsolved diseases, including
Parkinson's disease, Alzheimer's, stroke, atherosclerosis,
complications from diabetes and protection of bone marrow cells from
cancer chemotherapy and radiotherapy. Solutions for any of these
diseases could represent billion dollar annual market opportunities.
