iBio Passes Commercial Technology Transfer Milestone

NEWARK, DEL., April 22, 2013 – PRNewswire – iBio, Inc. (NYSE MKT: IBIO) today announced the achievement of a critical technology transfer milestone verified by an independent third party laboratory. The validation milestone comprised proof that an independent party, without guidance or assistance from iBio, could use the iBioLaunch™ system to reliably replicate production of commercial yields of targeted biopharmaceuticals including vaccines and therapeutics.

“In light of our recently announced commercial collaborations, this is an important demonstration that our technology can be readily utilized by others for commercialization of their respective products,” said Robert Erwin, iBio’s President. “To prove that, we designed the milestone to require the third party laboratory to implement the iBioLaunch system without assistance from iBio.”

On February 19, iBio announced the grant of a license for the use of its iBioLaunch platform for development and production of a licensee’s proprietary therapeutic product. On April 9, iBio announced another licensee’s commitment for development of a multiproduct commercial facility based upon the iBioLaunch platform.

Although it is now proven that the iBioLaunch system could be employed by third parties even without support or guidance from iBio, iBio’s actual business commitments to its licensees include assisting them to efficiently implement standard operating procedures for the use of iBio’s proprietary technology, and provision of quality assurance and quality control documentation and procedures for product and site-specific implementation. When required, iBio also provides staff training in collaboration with the Fraunhofer USA Center for Molecular Biotechnology, which operates a state-of-the-art cGMP pilot facility in Delaware based on the iBioLaunch platform.
