SAN FRANCISCO, March 6, 2014 (GLOBE NEWSWIRE) -- Amarantus Bioscience Holdings, Inc. (OTCQB:AMBS), a biotechnology company focused on the discovery and development of novel diagnostics and therapeutics related to endoplasmic reticulum stress, cell cycle dysregulation, neurodegeneration and apoptosis, today announced that it entered into an exclusive option agreement with the University of Massachusetts to license the University's method of use intellectual property surrounding the use of MANF and CDNF for the treatment of antibiotic-induced ototoxicity. The option agreement includes all intellectual property covering the use of the MANF-Family of proteins (MANF and CDNF) for antibiotic-induced ototoxicity and certain other disorders of the ear. The Company owns composition of matter patents and various composition and method of use patent applications for MANF and derivative sequences for protein therapeutic, gene therapy and certain cell therapy applications.

"Adding the orphan indication antibiotic-induced ototoxicity to our growing list of orphan applications for MANF is a tremendous step forward for the Company as we continue to build a world-class collaborative effort to exploit the full breadth of medical applications for MANF," said Gerald E. Commissiong, President & CEO of Amarantus. "The enabling data produced by the tremendous work of Dr. Lawrence M. Schwartz and his team at UMass Amherst was funded through our grant awarded by the Center of Excellence in Apoptosis Research and we intend to continue our strategy of gaining non-dilutive capital to drive our plans forward. With this agreement we are continuing to execute upon our strategy of building our intellectual property portfolio through sponsored research agreements with leading academic collaborators and expect this strategy to continue to pay dividends for the Company and our collaborators going forward. The scientific interest in MANF seems to be increasing on almost a daily basis."

Antibiotic-induced ototoxicity has been associated with at least 18 marketed drugs to date, particularly amynoglycosides. It is estimated that incidence of ototoxicity among amynoglycoside users is approximately 25%. The market opportunity for a drug that can impact ototoxicity among antibiotic users is estimated at well over $250M.

Concurrently with this announcement, the Company has identified a new independent peer-reviewed article entitled "Spatiotemporal Expression of MANF in the Developing Rat Brain" from researchers at the University of Kentucky College of Medicine School, the Institute of Nutritional Sciences in China and the University of Maryland School of Medicine.
