Peregrine Pharmaceuticals Reports Fiscal Year 2006 Third Quarter Results

TUSTIN, Calif., March 13 /PRNewswire-FirstCall/ -- Peregrine Pharmaceuticals, Inc. (Nasdaq: PPHM), a biopharmaceutical company with a portfolio of innovative, clinical stage products for the treatment of viral diseases and cancer, today announced financial results for the third quarter of fiscal year 2006 ended January 31, 2006. The company reported a consolidated net loss of $3,113,000, or $0.02 per basic and diluted share, compared to $3,744,000, or $0.03 per basic and diluted share, for the same prior year period.

Total revenues for the current quarter were $1,528,000, of which $1,505,000 were attributable to Avid Bioservices, the company's wholly owned contract manufacturing subsidiary. This compares to total revenues of $1,353,000 for the comparable quarter last year. Results for the period benefited from increased revenues at Avid as it ramped up for the unit's new commercial production contract with Halozyme Therapeutics.

"Since we last reported, we have continued our progress in our key programs," said Steven W. King, president and CEO of Peregrine. "We completed planned patient enrollment in the Tarvacin™ Anti-Viral Phase I trial in Hepatitis C infected patients and presented positive top-line safety data in February, well ahead of our previous target of mid-2006. Presentation of this first human data was a major milestone for Tarvacin, our first-in-class targeted product candidate with a wholly new mechanism for addressing viral diseases and cancer. Moving forward, we are pursuing several strategies to accelerate our Tarvacin Anti-Viral and Tarvacin Anti-Cancer programs, as well as our Cotara® program in brain cancer. We are increasing our preclinical and clinical program collaborations with top researchers and institutions in target therapeutic areas and are also moving forward with plans to facilitate patient enrollment by initiating clinical trials outside the U.S., focusing initially on cancer studies for Tarvacin Anti-Cancer and Cotara."

Total costs and expenses increased $851,000 to $6,010,000 for the 2006 third quarter from $5,159,000 for the same quarter last year. This increase was primarily due to higher research and development expenses associated with the advancement of the company's clinical and preclinical product candidates combined with an increase in selling, general and administrative expenses. This was partially offset by a decrease in cost of sales associated with Avid Bioservices.

Interest and other income increased $1,316,000 during the current quarter over the prior year quarter primarily due to the recovery of a fully reserved for note receivable in the amount of $1,229,000 that was paid off in December 2005.

At January 31, 2006, the company had $15,664,000 in cash and cash equivalents, compared to $9,816,000 at fiscal year end April 30, 2005.

Update on Tarvacin™ Programs

Tarvacin Anti-Viral

Planned enrollment and dosing in the Tarvacin Anti-Viral Phase I Hepatitis C virus (HCV) trial was completed in mid-February. Positive top-line safety data from the study was presented at the "Viral Hepatitis in Drug Discovery and Development" conference in Boston on February 27th. Data from this trial should enable Peregrine to move rapidly into repeat dose studies in HCV, which the company expects to begin by mid-2006 and anticipates completing patient enrollment by calendar year-end. The company also expects to initiate and complete patient enrollment in an HCV combination therapy study by calendar year-end and is currently on track to achieve these goals. The Tarvacin Anti-Viral program is also expected to benefit from the recent addition of Dr. John G. McHutchison, a highly regarded global HCV expert, to the company's Scientific Resource Board.

Peregrine is also continuing to evaluate the potential of Tarvacin in preclinical models for the treatment of other serious viral infections including seasonal and pandemic influenza, cytomegalovirus and HIV. The company plans to initiate trials in one to two additional anti-viral indications during 2006 pending positive results from these preclinical studies.

To advance further its preclinical and clinical anti-viral programs, Peregrine is continuing to expand its collaborations with private contract laboratories, major universities and federal government agencies, including the National Institute of Allergy and Infectious Diseases and the U.S. Department of Defense (DOD).

Tarvacin Anti-Cancer

The Phase I trial of Tarvacin Anti-Cancer is now ongoing at five clinical sites. Peregrine is on track to complete patient enrollment in this trial by the end of calendar year 2006. The company is evaluating options to accelerate the program including expanding its Tarvacin Anti-Cancer studies to additional sites. Possibilities include initiating clinical research programs outside the U.S.

Early evidence of Tarvacin's potential to treat a number of major solid tumor cancers was further boosted during the quarter when Peregrine's research collaborators at the University of Texas Southwestern Medical Center at Dallas published a study in the International Journal of Oncology reporting that a mouse equivalent of the Tarvacin antibody in combination with standard chemotherapy demonstrated encouraging efficacy in both shrinking primary tumors and reducing metastatic disease in well-validated preclinical pancreatic cancer models. In January 2006, the Defense Department awarded a second grant to UT Southwestern to conduct preclinical studies of Tarvacin Anti-Cancer as a potential treatment for prostate cancer. Results from these studies are expected to help accelerate the start of additional clinical trials once the current Phase l cancer trial is successfully completed. With this new project, the total DOD commitment to Tarvacin prostate cancer research exceeds one million dollars. Altogether more than three million dollars in aggregate grant funding has been awarded to UT Southwestern researchers to study Tarvacin in anti-cancer and anti-viral applications demonstrating a growing support for this first-in-class targeted therapeutic.

Update on Cotara® Program

Peregrine is continuing its Cotara development program in patients with recurrent brain cancer through its collaboration with the New Approaches to Brain Tumor Therapy (NABTT) Consortium. The company expects to complete enrollment in the NABTT study by calendar year-end. In addition, Peregrine is actively evaluating plans to initiate a Cotara clinical study outside the U.S. to expedite clinical development.
