Form 8-K for ZOGENIX, INC.

Item 8.01. Other Events.
On September 3, 2014, Daravita Limited ("Daravita") filed suit in the United States District Court for the District of Delaware against Actavis Laboratories FL, Inc. and certain of its affiliates ("Actavis"). Daravita has licensed rights under certain patents covering Zohydro® ER (hydrocodone bitartrate) Extended-Release Capsules, CII to Zogenix, Inc. ("Zogenix"). Under the Zohydro ER license agreement, Daravita has the right to control the enforcement of these patents and related proceedings involving Zohydro ER and any prospective generic entrant.
As previously reported, on August 13, 2014, Zogenix received a notice from Actavis concerning its filing of an Abbreviated New Drug Application ("ANDA") containing a "Paragraph IV" patent certification with the U.S. Food and Drug Administration (the "FDA") for a generic version of Zohydro ER. The FDA will determine whether Actavis may be eligible for the 180-day exclusivity period described in 21 U.S.C. § 355(j)(5)(B)(iv).
The lawsuit filed by Daravita alleges that Actavis has infringed U.S. Patent Nos. 6,228,398 (the "'398 patent") and 6,902,742 (the "'742 patent") by filing its ANDA seeking approval from the FDA to market a generic version of Zohydro ER prior to the expiration of these patents. The '398 patent and '742 patent are listed in the FDA's Approved Drug Products with Therapeutic Equivalence Evaluations, commonly known as the Orange Book. The patent infringement lawsuit was filed within 45 days of receipt of the notice letter, thereby triggering a stay of FDA approval of the Actavis ANDA until the earlier of the expiration of a 30-month period from the receipt of the notice letter, the expiration of the '398 patent and '742 patent, the entry of a settlement order or consent decree stating that the '398 patent and '742 patent are invalid or not infringed, a decision in the infringement case that is favorable to Actavis, or such shorter or longer period as the court may order.
Regardless of the outcome of any litigation, no ANDA can receive final approval from the FDA before expiration of the regulatory exclusivity period for Zohydro ER. Specifically, the FDA has granted Zohydro three years of regulatory exclusivity, which expires in October 2016.
Daravita and Zogenix intend to vigorously enforce the intellectual property rights relating to Zohydro ER to prevent the marketing of infringing generic products prior to the expiration of their patents. The '398 patent and the '742 patent each expire on November 1, 2019. However, given the unpredictability inherent in litigation, Zogenix cannot predict the outcome of this matter or guarantee the outcome of any litigation.
For a discussion of risks related to the ANDA filing by Actavis, see the "Risk Factors" section and the discussion of "Intellectual Property" under the "Business" section of Zogenix's Annual Report on Form 10-K for the year ended December 31, 2013 filed with the Securities and Exchange Commission (the "SEC") on March 7, 2014 and the "Risk Factors" section of Zogenix's Quarterly Report on Form 10-Q for the period ended June 30, 2014 filed with the SEC on August 6, 2014, including the risks described under the headings "The patent rights that we have in-licensed covering Zohydro ER are limited to a modified release composition containing hydrocodone. As a result, our market opportunity for this product may be limited by the lack of patent protection for the active ingredient itself and other formulations of hydrocodone" and "We face intense competition, including from generic products, and if our competitors market and/or develop treatments for migraine, pain or psychotic disorders that are marketed more effectively, approved more quickly than our product candidates or demonstrated to be safer or more effective than our products, our commercial opportunities will be reduced or eliminated," as well as any updates to such sections contained in Zogenix's subsequent reports filed with the SEC.
