Amarantus Announces Successful Delivery and Distribution of MANF in Preclinical Model to Brain Areas Involved in Parkinson's Disease

- Collaboration Using Renishaw Plc's Convection-Enhanced Delivery Device Demonstrated MANF Can be Precisely Delivered to Parkinson's-Associated Brain Areas -

- Delivery and Distribution Data Solidifies Rationale for Preclinical Development of MANF as a Potential Disease-Modifying Treatment in Parkinson's Disease  -

SAN FRANCISCO, CA, and GENEVA, SWITZERLAND –  Amarantus Bioscience Holdings, Inc. (OTC: AMBS), a biotechnology company focused on developing therapeutic and diagnostic products for neurological disorders and orphan indications, announced that it has completed a study of mesencephalic-astrocyte-derived neurotrophic factor (MANF) administration to the putamen and the substantia nigra of pigs by convection-enhanced delivery. This study generated MANF brain delivery and distribution data, further supporting the rationale for MANF's development in the treatment of Parkinson's disease (PD). The study was conducted in the United Kingdom in collaboration with Renishaw plc's (LON:RSW) Neurological Applications Department and its leading academic partner, Functional Neurosurgery Research Group at the University of Bristol.

In previously reported studies, MANF has been demonstrated by multiple laboratories to be neuroprotective and neurorestorative in rat models of Parkinson's disease. The current study demonstrated that: (i) MANF can be delivered to the porcine putamen and substantia nigra, brain areas centrally involved in PD, and (ii) that pharmacologically efficacious levels are achieved using Renishaw's convection-enhanced delivery device currently in human clinical development. The porcine brain is considered a good model to evaluate the feasibility of delivering therapeutic agents to the human brain, as it has a significantly larger brain volume than that of a rat or non human primate (NHP). These data demonstrating accurate surgical targeting and distribution of MANF mark an important step in the development of MANF for the treatment of PD.

"We are very encouraged by this important set of data demonstrating that MANF can be delivered to the brain with great accuracy," said Gerald E. Commissiong, President & CEO of Amarantus. "MANF was precisely delivered to sites of the brain affected by Parkinson's disease and the volume of distribution was thought to be sufficient to elicit a treatment effect. This data further positions Amarantus in the Parkinson's disease space, as we are preparing to initiate our Phase 2b small molecule program of our lead product candidate, eltoprazine, in Parkinson's disease levodopa-induced dyskinesia and continue with the development of MANF as a potential disease-modifying treatment for PD."

In the study single bilateral catheters were implanted into the putamen and the substantia nigra, respectively. High accuracy to within 0.5 mm of the planned target was demonstrated by post-operative magnetic resonance imaging (MRI) while infusing Gadolinium-DTPA (Gd) during real-time scanning. MANF was administered to the porcine brain target sites 14 days later by convection-enhanced delivery. No evidence of reflux was detected. Immuno-staining on serial axial and coronal sections combined with volumetric analysis demonstrated MANF distribution volumes of 307 mm3 and 105 mm3 for the putamen and the substantia nigra, respectively. The observed distribution in porcine putamen was comparable to the one required to elicit neuroprotection in the rat PD model. Moreover, MANF and Gd distribution volumes correlated well and Gd did not appear to alter MANF's pattern of distribution. The Company believes these data provide a firm basis for studies in NHPs as well as subsequent human clinical trials.

The Company expects to publish further data from this study in peer-reviewed journals and at scientific congresses over the course of 2015.

About Parkinson's Disease

Parkinson's disease is a chronic, progressive neurological disorder that causes motor symptoms such as tremors, rigidity and slowed movements as well as non-motor symptoms including cognitive impairment and autonomic dysfunction. The Parkinson's Disease Foundation estimates that there are approximately one million people living with PD in the United States and seven to ten million PD patients worldwide. The most commonly prescribed treatments for PD are levodopa-based therapies. There is currently no cure available for Parkinson's disease.

About Mesencephalic-Astrocyte-derived Neurotrophic Factor (MANF)

MANF (mesencephalic-astrocyte-derived neurotrophic factor) is believed to have broad potential because it is a naturally-occurring protein produced by the body for the purpose of reducing and preventing apoptosis (cell death) in response to injury or disease, via the unfolded protein response. By manufacturing MANF and administering it to the body, Amarantus is seeking to use a regenerative medicine approach to assist the body with higher quantities of MANF when needed. Amarantus is the front-runner and primary holder of intellectual property around MANF, and is initially focusing on the development of MANF-based protein therapeutics. MANF, a naturally-occurring protein that reduces and prevents apoptosis (programmed cell death) in response to injury or disease, was discovered utilizing Amarantus' proprietary PhenoGuard™ Protein Discovery Engine.

MANF's lead indication is retinitis pigmentosa, and additional indications including Parkinson's disease, diabetes and Wolfram's syndrome are currently being pursued. Further applications for MANF may include Alzheimer's disease, traumatic brain injury, myocardial infarction, antibiotic-induced ototoxicity and certain other rare orphan diseases currently under evaluation.
