BELMONT, Calif., March 24, 2011 (GLOBE NEWSWIRE) -- A-CUBE Inc. today announced that it has formed a Collaborative Research Agreement (CRA) with Sunnyvale-based ProtevoBio Inc. to design and construct three biobetter therapeutic monoclonal antibodies (MAbs). Terms were not disclosed.

"As a result of this exciting collaboration with ProtevoBio, A-CUBE now has sophisticated wetlab antibody engineering skills to expand our therapeutic monoclonal antibody program," said A-CUBE founder and President, Nobu Ota, PhD. "We are starting with a modest collaboration that we anticipate will expand in the future. A-CUBE focuses on the in silico design and intellectual property side of the equation, and ProtevoBio now provides us with antibody development, engineering and characterization."

"The A-CUBE monoclonal program is both unique and scientifically interesting," said Jeng Her, PhD, founder and CEO of ProtevoBio. "The ability to have in silico Rational Antigen Design capability that identifies biologically functional novel peptides that can additionally gain Composition of Matter IP is very powerful. We can move quickly on these projects and add a lot of value to both companies by these efforts," said Her, who co-founded KaloBios Pharmaceuticals, Inc., a therapeutic antibody company which has raised over $76 mil in private rounds since its inception in 2001. The protein-protein interaction selection system, the antibody Humaneering™ and the antibody affinity maturation technologies that he co-invented with Dr. Robert Balint and other scientists, have led to filing of 18 patents in U.S. and worldwide, and became the technology cornerstones for the pipeline of antibody drugs for inflammatory, oncology and infectious diseases at KaloBios, including KB001, an anti-Pseudomonas antibody licensed to Sanofi Pasteur in Jan, 2010. In addition to KaloBios, he was also a founding scientist and VP of R&D at Multispan, Inc., a company dedicated to developing GPCR-related specialty reagents and providing superior services for cell-based drug profiling, based on a mammalian expression system he co-developed.


A-CUBE Inc. is a venture capital backed company (funded by JAIC and Mr. Ben du Pont's which uses proprietary in silico algorithms to predict novel drug targets. This technology was developed by company founder and President Nobu Ota, PhD, and has been used to develop various monoclonal antibodies and candidate DNA vaccines for the treatment of diseases.
