Peregrine Pharmaceuticals Presents Data at 7th International Symposium on Anti-Angiogenic Agents
TUSTIN, Calif., Feb 14, 2005 /PRNewswire-FirstCall via COMTEX/ -- Peregrine Pharmaceuticals, Inc. (Nasdaq: PPHM) announced today that data relating to the production and characterization of human antibody versions of its 2C3 antibody was presented at the 7th International Symposium on Anti-Angiogenic Agents held in La Jolla, CA.
The 2C3 antibody is a mouse antibody that selectively blocks certain activities of the blood vessel growth factor known as Vascular Endothelial Growth Factor (VEGF). VEGF has been implicated as a key factor in the development of a variety of different diseases including cancer and various ocular disorders. The human antibodies are intended to be used in Peregrine's Vascular Targeting Agent (VTA) and anti-angiogenesis programs.
"The successful generation of these human antibodies is a key milestone in the continued development of our pre-clinical pipeline of products," said Steven King, Peregrine's president and CEO. "Having these human 2C3 equivalent antibodies should expedite the identification of clinical candidates based on this targeting platform."
In pre-clinical studies, 2C3 has shown potent anti-tumor activity in a variety of different solid tumors including an 85% reduction in blood vessel formation in breast cancer metastases. Affitech AS of Oslo, Norway generated the human 2C3 equivalent antibodies in collaboration with Peregrine.

Peregrine's vascular research programs fall under several different proprietary platforms, including Anti-Phospholipid Therapy (APT), Vascular Targeting Agents (VTAs), Anti-Angiogenesis and Vasopermeation Enhancement Agents (VEAs).
Peregrine recently received approval from the FDA for its Tarvacin™ Phase I study for the treatment of cancer. Tarvacin, a novel anti-cancer agent, is part of Peregrine's Anti-Phospholipid Therapy (APT) platform, which binds directly to tumor blood vessels to inhibit tumor growth and development. The company plans on initiating the approved Phase I study in the near term.
Peregrine's most clinically advanced therapeutic program is known as Tumor Necrosis Therapy (TNT) and targets dead or dying tumor cells that are common to the majority of different tumor types. The company is developing a radioactive TNT agent that it has trademarked Cotara® for the treatment of cancer. The company is working with New Approaches to Brain Tumor Therapy (NABTT) Consortium to initiate the first part of Peregrine's U.S. Food and Drug Administration (FDA)-approved product registration trial using Cotara® to treat patients with brain cancer. Peregrine has also completed enrollment in a Phase I Cotara® clinical trial for the treatment of colorectal carcinoma at Stanford University Medical Center and is working closely with scientific advisors to design Phase II studies using Cotara® for other solid tumor indications. In addition, a TNT-based agent similar to Cotara® was developed under a licensing agreement in China and has received marketing approval for the treatment of advanced lung cancer.
The company's wholly owned subsidiary, Avid Bioservices, Inc. ( http://www.avidbio.com ), develops and manufactures monoclonal antibodies and recombinant proteins to support Phase I through Phase III clinical trials for biotechnology companies, including Peregrine.
