Amarantus Enters Into cGMP Manufacturing Agreement With Catalent Biologics for Production of MANF for Human Clinical Studies

- Catalent to Utilize Proprietary GPEx® Platform for Production of High Performance MANF Expressing Cell Line -

- cGMP Production of MANF to Enable Program Advancement Into Human Clinical Studies in Retinitis Pigmentosa, Retinal Artery Occlusion, Glaucoma and Parkinson's Disease -

SAN FRANCISCO and GENEVA, May 14, 2015 (GLOBE NEWSWIRE) -- Amarantus BioScience Holdings, Inc. (OTCQB:AMBS), a biotechnology company focused on developing therapeutic and diagnostic products for neurological disorders and orphan indications, today announced that it has entered into a manufacturing agreement with Catalent Pharma Solutions (NYSE:CTLT), the leading global provider of advanced delivery technologies and development solutions for drugs, biologics and consumer health products, for clinical-grade production of MANF (mesencephalic-astrocyte-derived neurotrophic factor). Under the agreement, Catalent will provide all cell line engineering, process development and clinical Good Manufacturing Practices (cGMP) biomanufacturing activities necessary for the rapid development of a high performance cell line expressing MANF protein that will thereafter be advanced into scale up for cGMP production.

"We selected Catalent as our development and manufacturing partner because they have the cGMP capabilities, expertise and proprietary technologies required to efficiently synthesize and scale up MANF production for human clinical use," said Gerald E. Commissiong, President & CEO of Amarantus. "Advancing MANF, our first internally-discovered therapeutic product candidate, into human clinical studies will be a major advancement for the Company. Rapid production of MANF in collaboration with Catalent will enable us to achieve this objective as quickly and in the most cost-effective manner possible. The Company is currently targeting the orphan ocular indication retinitis pigmentosa (RP) for first-in-man studies, expected to start in 2016."

The project will utilize Catalent's proprietary GPEx® technology, which creates high-expression, extremely stable cell lines with speed and efficiency, typically capable of getting drug development projects to clinic in one-third the time of traditional approaches. The advantages of applying GPEx® technology span from early feasibility studies, to clinical manufacturing and commercial scale production.

MANF is a naturally-occurring protein that reduces and prevents apoptosis (programmed cell death) in response to injury or disease. Amarantus is developing MANF for the treatment of orphan ocular indications, including retinitis pigmentosa (RP), and recently received orphan drug designation for MANF for the treatment of RP in the United States and in Europe. In addition, MANF proteins have demonstrated proof-of-concept in animal pre-clinical models to treat a wide range of conditions including retinal artery occlusion, glaucoma, Parkinson's disease (PD), diabetes and ischemic heart disease, among others.

With this announcement, Amarantus is initiating Investigational New Drug enabling (IND-enabling) studies to support a first-in-man clinical study with MANF. The Company has retained regulatory expertise to identify the fastest path to human proof-of-concept data by evaluating well-respected regulatory pathways available worldwide, and will be working judiciously towards this objective. Amarantus is targeting the initiation of first-in-man clinical studies for MANF in 2016.

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 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.
