ROCKVILLE, Md. and SAN FRANCISCO, Aug. 8, 2012 /PRNewswire/ -- Synthetic Biologics, Inc. (NYSE Amex: SYN), a developer of synthetic biologics and innovative medicines for unmet medical needs, and Intrexon Corporation (Intrexon), a synthetic biology company that utilizes its proprietary technologies to provide control over cellular function, today entered into a second worldwide exclusive channel collaboration through which Synthetic Biologics intends to develop and commercialize a series of monoclonal antibody (mAb) therapies for the treatment of certain infectious diseases not adequately addressed by existing therapies. Utilizing Intrexon's comprehensive suite of proprietary technologies, including the mAbLogix™ platform for rapid discovery of fully human mAbs, Synthetic Biologics' initial efforts will target three infectious disease indications. The collaboration may optionally be expanded to include up to an additional five infectious disease indications. Synthetic Biologics intends to disclose selected indications from time to time as business and commercial considerations dictate. Jeffrey Riley, Chief Executive Officer of Synthetic Biologics, Inc., stated, "Through this second worldwide exclusive collaboration, we are pleased to strengthen our relationship with Intrexon and develop new therapeutics for unmet medical needs, in an effort to build value for our shareholders.
