Advaxis, Vibalogics to develop storage-stable formulation for live Listeria vaccines

Advaxis, Inc., (OTCBB: ADXS), the live, attenuated Listeria monocytogenes (Listeria) immunotherapy company and Vibalogics GmbH, a German biologics manufacturing company, have agreed to co-develop a room temperature stable, processing technology for live vaccines originally engineered for Advaxis.

“This process, which we are currently developing for our Listeria immunotherapeutics, shows promise in its use with other living micro-organisms”

Most live vaccines are stored via freeze drying called lyophilization. This drying method may not be suitable for all products, as it frequently kills most of the microorganism; depending upon the organism type and related recovery and stability issues. Based on Vibalogics' drying experience, a new method has been found that allows for a room temperature, storage-stable form of Advaxis' live Listeria vaccines with a very high recovery.

"This process, which we are currently developing for our Listeria immunotherapeutics, shows promise in its use with other living micro-organisms," commented Advaxis Chairman/CEO Thomas A. Moore. "Although it is intended for use with Listeria, other companies and academic institutions that use living microorganisms (e.g., Salmonella, E. coli) may benefit from this process. This initiative does not require significant development funds from Advaxis, vastly increases the commercial properties of our products, and can increase our short- and long-term shareholder value."
