Peregrine and Stason Enter Into Agreement for Innovative Tumor Necrosis Therapy (TNT) Technologies

Agreement Includes Exclusive Rights to Develop TNT Products in Certain APEC Countries; Upon Successful Commercialization, Stason Has Option to Acquire Rights to Expand Coverage to Additional Regions

TUSTIN, CA and IRVINE, CA--(Marketwire - May 3, 2010) -  Peregrine Pharmaceuticals, Inc. (NASDAQ: PPHM), a clinical-stage biopharmaceutical company developing innovative monoclonal antibodies for the treatment of cancer and viral infections, and Stason Pharmaceuticals, a privately-held U.S.-based pharmaceutical company commercializing products globally since 1994, today announced agreements granting Stason certain exclusive development and commercialization rights to Peregrine's tumor necrosis therapy (TNT) technologies. Peregrine's lead TNT product candidate is Cotara®, a novel brain cancer therapy currently in Phase II clinical development. The company's TNT-based immunocytokines technology has also been licensed to Merck KGaA. 

"Stason's focus on oncology products for growing Asian markets expands the development of our TNT technologies to reach patients in this region who urgently need new options for the treatment of cancer," commented Steven W. King, president and chief executive officer of Peregrine Pharmaceuticals. "As we advance our clinical-stage pipeline of innovative products for oncology and viral infections, we will continue to pursue select partnering opportunities while retaining future potential value for our products in the major pharmaceutical markets."

Under the terms of the agreements, Stason is acquiring from Peregrine exclusive rights to Peregrine's TNT technologies in certain Asia-Pacific Economic Cooperation (APEC) countries. Peregrine has retained exclusive rights to its TNT technologies in the United States, European Union countries, and other select countries internationally. The agreements also include certain non-exclusive licenses for Peregrine's proprietary radiolabeling technologies and its fully-human NHS76 TNT antibody to enable and accelerate Stason's development of TNT products.

Harry Fan, president and CEO of Stason, stated, "This agreement represents a unique opportunity to acquire a novel, cutting-edge pharmaceutical technology package and bring innovative and promising treatments to millions of cancer patients in Asia and the Pacific Rim. We will also continue developing new applications and bioproducts based on TNT technologies to complement Peregrine's activities in the glioblastoma arena and will aggressively pursue new, diverse biotechnology markets. To advance these efforts, a new spin-off biopharmaceutical company headed by Dr. Eugene Mechetner will be formed which will focus on commercializing TNT technologies."

Stason will pursue drug development, clinical trial and commercialization activities in its exclusive APEC territories and both Stason and Peregrine will have the right to initiate new research activities worldwide. Peregrine will receive from Stason upfront fees, annual fees, and milestone payments over the term of the agreements, as well as double-digit royalty payments on net sales. Upon successful commercialization of a product and payment of predetermined royalties to Peregrine within the first seven years of this agreement, Stason will have a right to negotiate with Peregrine further expansion into other countries worldwide. If commercialization is not achieved within the first seven years, Stason will lose exclusivity to its APEC territories.

Peregrine's wholly-owned subsidiary Avid Bioservices will initially manufacture TNT products for Stason's research and development activities. Under the terms of the companies' agreement, Avid will be available to provide fee-based services to Stason for developing new processes and manufacturing products under cGMP conditions for clinical trials.

About TNT Technologies
TNT technologies use monoclonal antibodies to target intracellular tumor antigens in dead or dying (necrotic) tissues. This platform has demonstrated a broad-spectrum potential in solid tumors, including brain, lung, colon, breast, liver, prostate, and pancreatic cancers. Peregrine's lead TNT product Cotara is a monoclonal antibody conjugated with a radioisotope Iodine-131. Cotara is currently being evaluated in a Phase II clinical trial in the U.S. and India for the treatment of patients with glioblastoma multiforme (GBM), the deadliest form of brain cancer.

A unique approach to treating brain cancer patients, Cotara targets necrotic cells residing at the core of solid tumors. It transports and binds the radioactive iodine to the center of the tumor, allowing the radiation to destroy the tumor from the inside out. Prior data show that Cotara delivers 300-fold more radiation to the tumor than to normal tissues. Survival benefits for recurrent GBM patients were demonstrated in a prior Phase II trial, with 25% (7/28) of patients surviving over 1 year, 11% (3/28) surviving over 5 years, and 2 patients surviving over 9 years. These data compare favorably to the 5-year survival rate of 3.4% reported by the U.S. Brain Cancer Registry.

Cotara has Orphan Drug status in the U.S. and EU and Fast Track designation in the U.S.
