Arch Biopartners Provides MetaMx Development Update

TORONTO, ONTARIO–(Marketwired – Dec. 1, 2015) – Arch Biopartners Inc., (Arch or the Company) (TSX VENTURE:ACH)(OTCBB:FOIFF), today announced it has successfully completed quality control and pre-clinical validation of a synthesis of MetaMx™ which was produced by a third party chemistry manufacturer in the U.S.

The Arch team successfully confirmed the ability of this prototype of MetaMx to cross the blood brain barrier and target human brain tumor initiating cells (BTICs) and invasive glioma cells which were transplanted into immunocompromised mice. The Arch team also observed that the manufacturer’s version of MetaMx did not cause any adverse side effects in initial toxicology testing.

“Validating this third party synthesis of MetaMx was a critical step toward its first human trial,” said Richard Muruve, CEO of Arch Biopartners. “Arch can now proceed to engage a manufacturer to supply MetaMx to complete a three month toxicology program. The toxicology results and related pharmacology data will be key components of an Investigational New Drug application to perform a single dose, BTIC imaging trial involving patients with recurrent malignant glioma.”

MetaMx is composed of novel, synthetic peptides that target and attach to BTICs and invasive glioma cells, for the purpose of imaging, diagnosis and developing targeted therapies to improve patient outcomes and survival rates among glioblastoma patients.

About MetaMx and Malignant Glioma

Worldwide, there are approximately 70,000 new patients with malignant glioma each year and clinical outcomes for these patients have not changed substantially over the past 30 years. Average survival rates, for adults with more aggressive glioblastoma multiforme, remain at a dismal 12-15 months and long-term survivors (i.e. those surviving more than 3 years) are rare.

This poor survival rate is linked to BTICs and invasive glioma cells which represent disease reservoirs that are not detectable using current diagnostic techniques as they are indiscernible from normal tissue. As a result, these cells are usually left behind in brain tissue post surgery and often lead to tumor relapse and poor patient outcomes.

Therefore, a significant unmet medical need and commercial opportunity lies in the ability to target BTICs and invasive glioma cells for the purpose of imaging, diagnosing and developing targeted therapies to improve patient outcomes and survival rates.

Arch continues to prepare for a human trial to characterize the safety and pharmacokinetics of MetaMx and to demonstrate the efficacy of MetaMx to cross the human blood brain barrier and detect BTICs and invasive glioma cells. Such results in human patients will increase the value of MetaMx not only as a diagnostic and imaging tool but also as a potential drug delivery platform to destroy BTICs and invasive glioma cells.
