Peregrine Provides Update on Government-Sponsored Research Program

Two-Year Base Period Extended by Additional Six Months to Expand Evaluation of Bavituximab in Advanced Models of Viral Hemorrhagic Fever

TUSTIN, CA--(Marketwire - September 20, 2010) -  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 provided an update on its government contract with the Transformational Medical Technologies (TMT) program of the U.S. Department of Defense's Defense Threat Reduction Agency (DTRA). The two-year base period has been extended by six months to March 2011, and includes approximately $2.4 million in additional funding, to continue studying Peregrine's phosphatidylserine (PS)-targeting antibodies to reach proof of concept in advanced preclinical models of viral hemorrhagic fever (VHF) infections. 

New studies will evaluate bavituximab in CDC Category A VHF viruses. Upon demonstrating proof-of-concept in VHF, the TMT may exercise the first of two possible one-year option periods to remain within the government's maximum five-year period for contracts. Peregrine's TMT contract (HDTRA1-08-C-0003) began June 30, 2008 and was originally for a five-year period, including a two-year base period and three one-year option periods. The base period now provides for up to $24.7 million in funding for a total of up to $36.3 million in funding for the duration of the contract.
