Horizant NDA Resubmission and 505(b)(2) Regulatory Pathway
In November 2010, the U.S. Food and Drug Administration (the “FDA”) accepted for review the resubmission of the new drug application (“NDA”) from Glaxo Group Limited (d/b/a GlaxoSmithKline (“GSK”)) in response to the FDA’s Complete Response Letter regarding the NDA for Horizant™ (gabapentin enacarbil) Extended-Release Tablets for the treatment of moderate-to-severe primary restless legs syndrome. As described in more detail in XenoPort, Inc.’s Quarterly Report on Form 10-Q for the quarter ended September 30, 2010, in connection with the resubmission, GSK provided “paragraph iv” notices to Pfizer Inc as the NDA holder for Neurontin (gabapentin) Oral Capsules and to the owner of U.S. Patent 6,054,482 (a patent for Neurontin (gabapentin) Oral Capsules) in accordance with the Drug Price Competition and Patent Term Restoration Act of 1984. The 45-day period during which the owner of U.S. Patent No. 6,054,482 was permitted to file an action for patent infringement against GSK and initiate a 30-month stay in the FDA’s NDA review process expired on November 29, 2010, and, to our knowledge, no action for patent infringement regarding Horizant has been filed against GSK.
