TUSTIN, CA -- (MARKET WIRE) -- 03/11/11 -- Peregrine Pharmaceuticals, Inc. (NASDAQ: PPHM), a clinical-stage biopharmaceutical company developing first-in-class monoclonal antibodies for the treatment of cancer and viral infections, today announced financial results for the third quarter ended January 31, 2011 for its fiscal year (FY) 2011 and provided an update on the progress of its clinical development programs.

"We are continuing to advance our later-stage clinical programs for bavituximab and Cotara® by completing clinical studies and initiating new studies which can provide meaningful clinical data over the coming year," said Steven W. King, president and chief executive officer of Peregrine. "Since last quarter, we have initiated two new randomized Phase II trials for bavituximab, launched our first three investigator-sponsored trials, and completed patient treatment in our Phase II Cotara trial in recurrent glioblastoma multiforme and a bavituximab HCV study. Together, these advancing trials will help to further validate our technologies in oncology and viral disease indications. If our clinical and regulatory strategies are successful, they should add significant value."

Clinical Program Update

Bavituximab Oncology Trials

Peregrine is conducting three randomized Phase II trials in non-small cell lung cancer (NSCLC) and pancreatic cancer.

-- Phase IIb second-line NSCLC trial evaluating bavituximab with docetaxel

   versus docetaxel plus placebo. Enrollment of up to 120 patients is

   expected to be complete by mid-year 2011 with data unblinded by

   year-end 2011.



-- Phase IIb front-line NSCLC trial evaluating bavituximab with paclitaxel

   and carboplatin versus paclitaxel and carboplatin. Enrollment of up to

   86 patients is expected to be complete by mid-year 2011 with interim

   data from this open-label trial expected in the second half of 2011.



-- Phase II pancreatic cancer trial evaluating bavituximab with gemcitabine

   versus gemcitabine. This new trial was initiated in January 2011 and

   seeks to enroll up to 70 patients with previously untreated stage IV

   pancreatic cancer.

In addition to its company-sponsored trials, Peregrine has launched an investigator-sponsored trials (IST) program to evaluate further bavituximab's broad potential in different oncology indications and therapeutic combinations.

-- Phase I/II trial evaluating bavituximab combined with sorafenib in

   approximately 50 patients with advanced liver cancer. This IST is being

   conducted at University of Texas Southwestern Medical Center.

-- Phase Ib trial evaluating bavituximab combined with pemetrexed and

   carboplatin in up to 25 front-line NSCLC patients. This IST is being

   conducted at the University of North Carolina at Chapel Hill.

-- Phase I trial evaluating bavituximab combined with paclitaxel in

   patients with HER2-negative metastatic breast cancer. This IST is being

   conducted at the Arizona Cancer Center at UMC North.

Cotara® Phase II Brain Cancer Trial

In December 2010, Peregrine completed treatment of the last patient in a Phase II trial in recurrent glioblastoma multiforme (GBM). The Company expects to report data by mid-year 2011 and to meet with the FDA in the second half of 2011 to determine the optimal registration pathway for Cotara.

Bavituximab HCV Trials

In January 2011, Peregrine initiated a new randomized Phase II trial in patients with previously untreated genotype-1 hepatitis C virus (HCV) infection. This open-label trial is designed to determine the early virologic response (EVR) rate of patients after 12 weeks of therapy with bavituximab in combination with the antiviral drug ribavirin versus standard of care, pegylated interferon alpha 2a and ribavirin.

In addition, Peregrine completed enrollment in a Phase I trial to evaluate the safety and pharmacokinetics of bavituximab in patients coinfected with chronic HCV and HIV and expects to report data at the 46th Annual Meeting of the European Association for the Study of the Liver (EASL), March 30 to April 3, 2011.

Preclinical Research

Preclinical data from four studies investigating bavituximab and other phosphatidylserine (PS)-targeting antibodies have been accepted for poster presentation at the 102nd Annual Meeting of the American Association for Cancer Research (AACR), April 2-6, 2011.

Peregrine has conducted preclinical research to evaluate its PS-targeting antibodies for viral hemorrhagic fever (VHF) infections under a government contract. This contract, which will expire on March 15, 2011, has provided $23.5 million in total funding through January 31, 2011.

Intellectual Property

On February 1, 2011, Peregrine's phospholipid-targeting intellectual property portfolio was further strengthened with the issuance of U.S. patent #7,879,801, titled "Compositions Comprising Cell-Impermeant Duramycin Derivatives." Expanding the coverage for therapeutic and imaging applications of Peregrine's novel technologies, the patent was granted to the University of Texas System and is exclusively licensed to Peregrine.

Financial Results

Total revenues for the third quarter of FY 2011 were $2,883,000, compared to $9,877,000 for the same quarter of the prior fiscal year. This decrease was primarily attributed to a reduction in government contract revenue, due to the level of services performed under the contract terms, as well as lower contract manufacturing revenue from Peregrine's subsidiary Avid Bioservices, due to the level and timing of services provided to its third-party clients. For FY 2011, Avid's contract manufacturing revenue from third-party clients is expected to be in the lower half of its original estimated range of between $8 million and $12 million. Avid will continue to utilize available capacity and resources to begin preparing for the future clinical development and potential commercialization of bavituximab and Cotara, while also seeking to grow its base of third-party clients.

Total costs and expenses in the third quarter of FY 2011 were $11,726,000, compared to $11,194,000 in the third quarter of FY 2010. For the third quarter FY 2011, research and development expenses were $7,053,000, compared to $7,322,000 for the third quarter of FY 2010.

Peregrine's consolidated net loss was $8,929,000, or $0.14 per share, for the third quarter of FY 2011, compared to a net loss of $1,538,000 or $0.03 per share, for the same quarter of the prior year.

Peregrine reported $24,068,000 in cash and cash equivalents at January 31, 2011, compared to $17,268,000 at October 31, 2010 and $19,681,000 at fiscal year ended April 30, 2010.

More detailed financial information and analysis may be found in Peregrine's Quarterly Report on Form 10-Q, which was filed with the Securities and Exchange Commission today.
