NuPathe Announces Allowance of Additional U.S. Patent for ZECUITY

CONSHOHOCKEN, PA--(Marketwired - Sep 10, 2013) - NuPathe Inc. (NASDAQ: PATH) today announced that the United States Patent and Trademark Office has issued a notice of allowance for U.S. Patent application 13/407,434. This application relates to NuPathe's innovative iontophoretic patch that uses a two-stage delivery sequence to transdermally deliver sumatriptan. This, and other proprietary technology, is incorporated into NuPathe's lead product, ZECUITY® (sumatriptan iontophoretic transdermal system), the first and only FDA approved patch for migraine.

"This patent allowance is significant for NuPathe as a key technological breakthrough of ZECUITY is its ability to transdermally deliver the most commonly prescribed migraine medication, which cannot be passively absorbed through the skin," said Armando Anido, chief executive officer of NuPathe.

Given this action, NuPathe expects the patent to issue within the next few months. Once issued, the patent will provide additional protection for ZECUITY and will be the sixth patent listed in the U.S. Food & Drug Administration's (FDA) Orange Book. NuPathe has additional U.S. patents covering ZECUITY that expire between 2027 and 2029 and patent applications pending in the U.S. and other territories.

About ZECUITY®
ZECUITY (sumatriptan iontophoretic transdermal system) is indicated for the acute treatment of migraine with or without aura in adults. ZECUITY is a single-use, battery-powered patch applied to the upper arm or thigh during a migraine. Following application and with a press of a button, ZECUITY initiates transdermal delivery (through the skin), bypassing the gastrointestinal tract. Throughout the four-hour dosing period, the microprocessor within ZECUITY continuously monitors skin resistance and adjusts drug delivery accordingly to ensure delivery of 6.5 mg of sumatriptan, the most prescribed migraine medication in the U.S., with minimal patient-to-patient variability.

Important Safety Information
Patients should not take ZECUITY if they have heart disease, a history of heart disease or stroke, peripheral vascular disease (narrowing of blood vessels to your legs, arms, stomach or kidney), transient ischemic attack (TIA) or problems with blood circulation, uncontrolled blood pressure, migraines that cause temporary paralysis on one side of the body or basilar migraine, Wolff-Parkinson-White syndrome or other disturbances of heart rhythm. Very rarely, certain people, even some without heart disease, have had serious heart-related problems after taking triptans like ZECUITY.
