TUSTIN, CA and SAN DIEGO, CA--(Marketwire - November 29, 2010) - Avid Bioservices, Inc., a leading provider of integrated commercial and clinical manufacturing services and a subsidiary of Peregrine Pharmaceuticals, Inc., announced that company representatives will present a poster at IBC's Antibody Engineering & Therapeutics Conference in San Diego, CA. With a cGMP manufacturing facility in Orange County, CA, Avid will highlight its experience developing and implementing a comprehensive comparability program to increase the manufacturing yield to support larger Phase IIb clinical trials for Peregrine's lead monoclonal antibody bavituximab.

"Designing and implementing a robust comparability program was critical to advance Peregrine's bavituximab into larger Phase IIb clinical trials," said Richard Richieri, senior director, technical services, of Avid Bioservices. "We developed an integrated regulatory and manufacturing strategy to implement a second-generation process to increase yield and clinical supply of bavituximab. With input from regulatory, process sciences, and quality functions, we ensured a successful implementation of significant process changes to support larger clinical trials."

Avid's poster is titled "Demonstrating Comparability of a Phase II Monoclonal Antibody Product in Clinical Trials Resulting from Changes in Cell Line and Manufacturing Processes" and will be on display in the exhibit hall December 6-8, 2010 at the Hilton San Diego Bayfront Hotel.
