news.Amarantus BioScience Holdings (AMBS), a biotechnology company focused on developing therapeutic and diagnostic products for neurological disorders and orphan indications, has received a Notice of Allowance from the US Patent and Trademark Office (USPTO) for US Patent Application Serial No. 13/305,025 entitled, "Dopaminergic Neuronal Survival Promoting Factors and Uses Thereof."

Upon issuance, the patent will provide additional intellectual property protection for MANF (mesencephalic-astrocyte-derived neurotrophic factor) protein therapy and cell therapy.
The allowed patent claims cover compositions of matter and methods of use related to the Company’s proprietary manufacturing process for synthetic MANF and its administration.
Native MANF is currently under development for the treatment of orphan ocular indications, including retinitis pigmentosa (RP). Amarantus recently received orphan drug designation for MANF for the treatment in RP in the United States and in Europe.
In addition, MANF proteins have demonstrated proof-of-concept in preclinical models to treat a wide range of conditions including retinal artery occlusion, glaucoma, macular degeneration, Parkinson’s disease (PD), diabetes and ischemic heart disease, among others.
"This Notice of Allowance is another important element in our intellectual property strategy that we believe will allow us to fully exploit the fundamental value of the research and development ongoing for MANF, both internally and via our collaborations," said Gerald E. Commissiong, President & CEO of Amarantus.
"MANF is being developed as a potential therapeutic intervention for orphan ocular diseases and other chronic disorders for which few, if any, viable disease-modifying treatment options exist."
"This important step further signals the Company’s commitment to strengthening our industry-leading intellectual property portfolio surrounding MANF," said John W. Commissiong, Ph.D., Amarantus CSO and co-discoverer of MANF.
"We will continue to strengthen our robust intellectual property estate to further protect and maintain our proprietary rights, which we believe will not only allow us to capitalize on the known opportunities for MANF development, but will also further entrench Amarantus as the leading company for new collaborations in light of emerging potential MANF applications."
The USPTO issues a Notice of Allowance after it makes a determination that a patent should be granted from a patent application.
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(TM) Protein Discovery Engine.
