Home > Press > Arrowhead's new nanobioscience subsidiary plans preclinical studies and collaboration with NCI

Abstract:
Arrowhead Research Corporation (NASDAQ: ARWR), announced today that its new wholly-owned nanobioscience subsidiary has changed its name from "C Sixty Acquisition Corp". to "Tego BioSciences Corporation". The subsidiary recently acquired the assets of C Sixty, Inc. and is focused on the development of new protective products based on the anti-oxidant properties of modified buckministerfullerenes (also known as fullerenes or buckyballs). Tego is initially developing products to reduce oxidative damage caused by sun exposure, radiation therapy, and chemotherapy and mitigate complications associated with organ transplantation and tissue engineering.

Arrowhead's new nanobioscience subsidiary plans preclinical studies and collaboration with NCI

PASADENA, CA | Posted on June 25th, 2007

"Tego is set to commence preclinical animal studies in collaboration
with the National Cancer Institute this summer," said R. Bruce
Stewart, Chairman of Arrowhead. "Tego is in the process of assembling
a business and technical team with expertise in nanoparticle-based
therapeutics and skin care products."

The preclinical studies will be performed in the NCI's Nanotechnology
Characterization Lab (NCL) to measure the ability of a Tego fullerene
formulation to protect against harmful side effects of two
anti-cancer drugs, cisplastin and adriamycin. The first stage of the
studies will use NCL's resources, with follow on funding from Tego,
as appropriate.

The National Cancer Institute (NCI), working in concert with the
National Institute of Standards and Technology (NIST) and the U.S.
Food and Drug Administration (FDA), established the Nanotechnology
Characterization Laboratory (ncl.cancer.gov) to perform preclinical
efficacy and toxicity testing of nanoparticles. The NCL serves as a
national resource and knowledge base for all cancer researchers to
facilitate the regulatory review of nanotechnologies intended for
cancer therapies and diagnostics. By providing the critical
infrastructure and characterization services to nanomaterial
providers, the NCL can accelerate the transition of basic nanoscale
particles and devices into clinical applications, thereby reducing
suffering and death from cancer.

About Arrowhead Research Corporation
Arrowhead Research Corporation (www.arrowheadresearch.com) is a
publicly-traded nanotechnology company commercializing new
technologies in the areas of life sciences, electronics, and energy.
Arrowhead is building value for shareholders through the progress of
majority owned subsidiaries founded on nanotechnologies originally
developed at universities. The company works closely with
universities to source early stage deals and to generate rights to
intellectual property covering promising new nanotechnologies.
Currently, Arrowhead has four subsidiaries commercializing nanotech
products and applications, including anti-cancer drugs, RNAi
therapeutics, carbon-based electronics and compound semiconductor
materials.

About Tego BioSciences Corporation

Tego BioSciences Corporation (www.tegobio.com) is developing and
commercializing therapeutics and other products based on the
antioxidant properties of modified fullerenes. The patent protected
platform forms the basis for several products. The company is
initially focused on developing products to reduce oxidative damage
caused by sun exposure, radiation therapy, and chemotherapy and
mitigate complications associated with organ transplantation and
tissue engineering. For other applications of derivatized fullerenes
such as MRI imaging or central nervous system disorders, Tego
BioSciences will establish a program to license and partner the
commercialization of its intellectual property to third parties.

Fullerenes are a highly structured, nanoscale form of carbon, similar
to carbon nanotubes. 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.
