Avid Bioservices to Make Three Presentations at IBC's Biopharmaceutical Development and Production Week Conference Highlighting Its Innovative Applications for Developing Purification Methods and Quantitative Analytical Assays to Achieve and Monitor Manuf

TUSTIN, CA--(Marketwired - Mar 31, 2015) - Avid Bioservices, Inc., the contract manufacturing subsidiary of Peregrine Pharmaceuticals, Inc., today announced that it will present three posters at IBC's Biopharmaceutical Development and Production Week Conference to be held in Huntington Beach, California, March 30-April 2, 2015. These presentations will highlight Avid's expertise in optimizing purification techniques to remove process-related impurities, as well as strategies for developing process-specific host cell protein antigens that can be used for the development of impurity assays.

Avid will present the following posters, which will be on display Wednesday, April 1^st and Thursday, April 2^nd at the Hyatt Regency Huntington Beach Resort and Spa Hotel:

• "Generation of Host Cell Protein Assay Reagents for Development of a Process-Specific Host Cell Protein Assay"
  Presented by Jeanette Doerr, Ph.D., Senior Scientist, Molecular Cell Biology
  
  
• "Variability of Triton X-100 Impacts Product Solution Clarity During Solvent/Detergent Treatment"
  Presented by David Briggs, Ph.D., Associate Scientist, Manufacturing Science and Technology
  
  
• "Reducing Residual DNA with No Impact on Critical Quality Attributes: A Case Study Using Modified Ceramic Hydroxyapatite (CHT) Conditions to Selectively Remove Host Cell DNA Contaminants"
  Presented by Payam Farahani, Associate Scientist, CMC & Process Sciences

"In one case study, the Avid teams share examples of process improvements made by applying innovative techniques for purification, while maintaining critical quality attributes (CQAs). We have been able to make significant advancements in purification techniques for complex glycoproteins in order to meet the specific needs of our clients' advancing programs," said Connie Chang, senior director of CMC and Process Sciences for Avid Bioservices. "In another case study, we share strategies for generating process specific Host Cell Proteins (HCP) that can be used to develop reagents for process specific impurity assays. Host cell proteins contaminants for biological products are of significant interest to regulatory agencies and this presentation shares our experience in developing the reagents that can be used to develop process specific HCP assays for late stage development and commercialization."
