NuPathe Inc. Announces Allowance of Additional U.S. Patent Application for NP202

CONSHOHOCKEN, PA--(Marketwire - July 11, 2012) - NuPathe Inc. (NASDAQ: PATH), a biopharmaceutical company focused on the development and commercialization of branded therapeutics for diseases of the central nervous system, today announced that the United States Patent and Trademark Office (USPTO) has issued a Notice of Allowance for U.S. Patent Application 11/195,845 titled "Drug Containing Implants and Methods of Use Thereof." The allowed claims relate to a rod-shaped implant or structure that delivers therapeutic levels of risperidone for 20 to 190 days as well as to methods for treating medication noncompliance-associated diseases including schizophrenia and bipolar disorder. Given this action, NuPathe expects the patent to issue within the next few months. Once issued, it will provide patent protection through December 2027 for NP202, NuPathe's long-term biodegradable risperidone implant for the treatment of schizophrenia and bipolar disorder. NuPathe has a portfolio of additional licensed patent applications pending in the U.S. and other territories for NP202.

"As we progress towards filing an IND application for NP202 next year, we continue to strengthen our intellectual property," said Jane Hollingsworth, chief executive officer of NuPathe. "Non-compliance with currently available schizophrenia medications is high, and the resulting patient relapse is serious and costly. With three-month dosing, we believe that NP202 will be a breakthrough for patients struggling with this disease."

The inventors of the patent, which NuPathe exclusively licenses from the University of Pennsylvania, are Steven J. Siegel, M.D., Ph.D., Professor of Psychiatry and Director of the University of Pennsylvania's Translational Neuroscience Program, and Karen I. Winey, Professor of Materials Science and Engineering of the University of Pennsylvania's School of Engineering.

About NP202
NP202 is a long-acting, biodegradable risperidone implant formulated with NuPathe's LAD™ technology. NP202 is being developed to provide long-term, steady, therapeutic levels of risperidone with a single dose in a small, easy-to-administer and tolerable implant to treat schizophrenia and bipolar disorder. By providing three months of continuous drug delivery compared with current therapies of two weeks to one month, NuPathe believes NP202 will improve patient compliance, reduce psychotic breaks, reduce physician visits and improve patient functionality. NuPathe expects to file an Investigational New Drug application with the United States Food and Drug Administration in 2013.
