NuPathe Inc. (NASDAQ: PATH), an emerging 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 has issued a notice of allowance for U.S. Patent application 12/142,604 entitled "Pharmacokinetics of Iontophoretic Sumatriptan Administration." This application relates to methods of treating a migraine by administering sumatriptan using an iontophoretic patch to achieve consistent therapeutic plasma levels with low patient-to-patient variability. Given this action, NuPathe expects the patent to issue within the next few months. Once issued, it will provide additional patent protection through April 2027 for NP101, NuPathe's lead product candidate for the treatment of migraine.

This coverage is in addition to that provided by NuPathe's U.S. Patent No. 7,973,058 entitled "Transdermal Methods and Systems for Delivery of Anti-Migraine Compounds," which expires in April 2027, and its U.S. Patent No. 6,745,071 entitled "Iontophoretic Drug Delivery System," which expires in February 2023. Upon approval of NuPathe's New Drug Application (NDA) for NP101, NuPathe expects to list all three patents in the U.S. Food & Drug Administration's (FDA's) Orange Book. NuPathe also has additional patent applications pending in the U.S. and other territories for its migraine patch.

"Issuance of this patent will further strengthen our intellectual property related to NP101," said Jane Hollingsworth, chief executive officer of NuPathe. "If approved, our breakthrough technology will offer the first-ever patch for migraine, providing rapid, consistent and controlled delivery through the skin of the most widely prescribed migraine medication. We look forward to re-submitting our NDA for the migraine patch in the first half of this year."

About the Migraine Patch (NP101 or Zelrix) NP101 is an active, single-use, transdermal patch in development for the treatment of migraine. If approved, it will be the first transdermal patch for the treatment of migraine. The patch actively delivers sumatriptan, the most widely prescribed migraine medication. In clinical trials involving more than 10,000 applications, NP101 offered patients fast onset and sustained relief of debilitating migraine symptoms including headache pain and migraine-related nausea (MRN). Because NP101 delivers sumatriptan transdermally, it may be an attractive treatment option for many of the approximately seven million migraineurs who might otherwise delay or avoid taking medication due to MRN. In addition, clinical trials suggest that many migraineurs fail to respond consistently to orally administered medications. This may result from a variety of causes including gastroparesis, which is low and inconsistent absorption of medication in the gut due to reduced gastric motility (or stomach slowing). The patch utilizes SmartRelief, NuPathe's proprietary transdermal delivery technology that allows the rapid yet tightly controlled transport of medication through the skin using a process called iontophoresis. As a result and based on clinical trial experience, the patch may offer a low incidence of triptan sensations that include chest tightness, flushing and feelings of pressure and numbness.
