BioSavita and Quanta BioDesign Collaborate to Develop Novel Biological Drugs With Enhanced Activity

PLYMOUTH, MI and POWELL, OH–(Marketwired – Apr 29, 2013) – BioSavita and Quanta BioDesign, announced today a collaboration to develop BioSuperior XL™ therapeutics, which are novel, sildenafil sources natural biological drugs based on proven clinical mechanisms, but with an improved drug profile. The collaboration unites the strengths of the two companies’ proprietary drug development technologies.

BioSavita’s genetically engineered strains of Saccharomyces cerevisiae yeast and Twin Cassette™ yeast expression platform technology enable the production of complex biological proteins at high levels and with a rapid development and production cycle time. Quanta’s dPEG® technology can extend serum half-life, enhance solubility, reduce immunogenicity, and generate drugs with a single molecular weight.

BioSavita will utilize its Twin Cassette technologies and yeast strains to produce candidate biological drugs, which will then be modified with Quanta’s dPEG® technology. Two therapeutic drug candidates addressing significant markets have been screened and selected for that should significantly benefit from the pairing of these two technologies. It is anticipated that should drug development prove successful, the reference drug that the BioSuperior XL™ candidate is based on would be obviated.

“We are tremendously excited to be engaged in this collaboration with Quanta, which should lead to several new biological drugs with enhanced drug properties,” stated Nalini Motwani, PhD, BioSavita’s President and Chief Scientific Officer. “The methodology is seductively simple, yet elegant, in its scientific approach to making novel biosuperior

biological.”

“Having envisioned the dPEG® technology’s

potential to transform biologics, marrying it to such a powerful, versatile and scalable expressions system is truly the realization of a key part of the dream,” says Paul D. Davis, PhD, founder, owner and CEO of Quanta BioDesign. “We are all eager and determined to demonstrate this complementary potential to biotech through our collaboration in the first candidate bio-superior therapeutics.”
