biOasis Advances Its Lysosomal Storage Disease Program with a Knockout Model for Sandhoff Disease

"biOasis initiates pivotal study using a knockout model for Sandhoff Lysosomal Storage Disease"

VANCOUVER, BRITISH COLUMBIA--(Marketwired - Sept. 9, 2014) - BIOASIS TECHNOLOGIES INC. (OTCQX:BIOAF)(TSX VENTURE:BTI), announces the commencement of a new phase of its Lysosomal Storage Disease program with a study focused on a knockout model for Sandhoff Disease. The study, to be conducted at The University of British Columbia ("UBC"), will assess the use of therapeutics based on biOasis' proprietary Blood-Brain Barrier vectors, Transcend and Transcend(pep), to correct enzyme deficiencies within the Central Nervous Systems of genetically engineered animals deficient in the enzyme β-hexosaminidase subunit beta ("HEXB"), which is functionally deficient in sufferers of Sandhoff Disease.

The colony of HEXB-deficient animals that populate the "knockout" model have been under development for several months in the UBC laboratory of biOasis' founding scientist, Dr. Wilfred Jefferies of the University's renowned Michael Smith Laboratories. The animals will undergo six weeks of treatment with biOasis' proprietary therapeutics, fMTf-HEXB, a fusion protein consisting of Transcend and β-hexosaminidase subunit beta, and fMTfp-HEXB, a fusion protein consisting of Transcend(pep) and β-hexosaminidase subunit beta. The treatment period will commence in October when the colony's age and weight are ideal for treatment.

This is the first study where biOasis is utilizing fusion protein versions of its platform technologies. Both fMTf-HEXB and fMTfp-HEXB are classified as chimeric fusion proteins, hybrid proteins that are made of polypeptides that have varying functions or physico-chemical patterns. In the past, biOasis has used chemical conjugation methods to produce therapeutics for test purposes. The method was used because it is faster and less expensive for "proof of concept" purposes. However, chemical conjugations generally do not produce consistent molecular structures. biOasis' chimeric fusion proteins are designed to guarantee that each therapeutic is produced in a structurally consistent manner and that the binding sites of the respective Transcend and Transcend(pep) molecules are not masked, theoretically enhancing both the binding activity and the transport of therapeutics across the Blood-Brain Barrier.

"Our recent discovery and subsequent validation of Transcend(pep) as a carrier or shuttle of therapeutics into the brain are extremely encouraging. We now plan to treat animal that lack the HEXB enzyme and therefore mimic the human form of Sandhoff disease with the HEXB-Transcend(pep) fusion molecules. This is a crucial step towards advancing this novel therapeutic approach to the clinic," said lead researcher, Professor Jefferies.

"This study at UBC kicks off a new phase of our LSD program," said Rob Hutchison, CEO of biOasis Technologies. "All of the work that we and our partners have been doing with Transcend(pep) has given us the confidence that this program has the potential to be of great value for biOasis and its shareholders. To optimize the program, our team along with help from one of our partners, have worked to prepare clinically acceptable test materials and to this end, we're introducing fusion-based therapeutics rather than those that are chemically conjugated. After a lot of hard work and extensive planning, we're very pleased to be advancing our LSD program with this pivotal study."
