NuPathe Announces Allowance of Additional U.S. Patent Application for NP201

CONSHOHOCKEN, PA--(Marketwired - May 13, 2013) - NuPathe Inc. (NASDAQ: PATH) today announced that the United States Patent and Trademark Office (USPTO) has issued a notice of allowance for U.S. Patent application 11/784,526 entitled "Implants for the Treatment of Dopamine Associated States." This application relates to methods for treating dopamine associated states (such as Parkinson's disease) using a biodegradable polymer implant capable of delivering a dopamine modulating compound (such as ropinirole) gradually rather than with an initial burst and maintaining an effective plasma level of the compound for a specified delivery period. Given this action, NuPathe expects the patent to issue within the next few months. Once issued, it will provide patent protection into October 2027 for NP201, NuPathe's long-term biodegradable ropinirole implant for the treatment of Parkinson's disease and other dopamine associated disorders. NuPathe has additional licensed patent applications pending in the U.S. and other territories for NP201.

"This represents our second recent patent allowance from the USPTO as we continue to strengthen our intellectual property position around NP201," said Armando Anido, chief executive officer of NuPathe. "Seeking development partners for this program remains a business development objective for the Company."

The inventors of the allowed patent, which NuPathe exclusively licenses from the University of Pennsylvania, are Steven J. Siegel, M.D., Ph.D., Director of the University of Pennsylvania's Translational Neuroscience & Clinical Neuroscience Training Programs, and Terri B. Sebree, President of NuPathe.

About NP201NP201 is a long-acting formulation of ropinirole, a generic, FDA-approved dopamine agonist. Using NuPathe's long-acting delivery (LAD) technology, NP201 is designed to provide continuous delivery of Parkinson's disease medication for up to two months in an easy-to-administer and tolerable dose formulation. NuPathe is seeking a development partner for this product candidate.

About NuPatheNuPathe Inc. is a specialty pharmaceutical company focused on innovative neuroscience solutions for diseases of the central nervous system including neurological and psychiatric disorders. NuPathe's lead product, Zecuity (sumatriptan iontophoretic transdermal system), has been approved by the FDA for the acute treatment of migraine with or without aura in adults. In addition to Zecuity, NuPathe has two proprietary product candidates based on its LAD, or Long-Acting Delivery, biodegradable implant technology that allows delivery of therapeutic levels of medication over a period of months with a single dose. NP201, for the continuous symptomatic treatment of Parkinson's disease, utilizes a leading FDA-approved dopamine agonist, ropinirole, and is being developed to provide up to two months of continuous delivery. NP202, for the long-term treatment of schizophrenia and bipolar disorder, is being developed to address the long-standing problem of patient noncompliance by providing three months of continuous delivery of risperidone, an atypical antipsychotic. NuPathe is actively seeking partnerships to maximize the commercial potential for Zecuity and its other product candidates in the U.S. and territories throughout the world.
