Item 8.01. Other Events.
On September 29, 2014, Zogenix, Inc. ("Zogenix") received a paragraph IV certification from Alvogen Pine Brook, Inc. ("Alvogen") advising Zogenix of the filing of an Abbreviated New Drug Application ("ANDA") with the U.S. Food and Drug Administration (the "FDA") for a generic version of Zohydro® ER (hydrocodone bitartrate) Extended-Release Capsules, CII.
The certification notice alleges that the two U.S. patents listed in the FDA's Orange Book for Zohydro ER, with an expiration date in November 2019, will not be infringed by Alvogen's proposed product, are invalid and/or are unenforceable. Zogenix and its licensor are evaluating the paragraph IV certification and intend to vigorously enforce the intellectual property rights relating to Zohydro ER.
Zohydro ER was granted exclusivity by the FDA through October 2016; Zogenix submitted a supplemental New Drug Application for the next-generation capsule formulation of Zohydro ER on September 30, 2014.
The parties have 45 days from the receipt of the paragraph IV certification to commence a patent infringement lawsuit against Alvogen that would automatically stay, or bar, the FDA from approving Alvogen's ANDA for 30 months or until a district court decision that is adverse to the asserted patents, whichever is earlier.

Zogenix cautions you that statements included in this report that are not a description of historical facts are forward-looking statements. Words such as "plans," "believes," "expects," "anticipates," and "will," and similar expressions, are intended to identify forward-looking statements, and are based on Zogenix's current beliefs and expectations. Such statements include, without limitation, statements regarding Zogenix's intention to vigorously enforce its intellectual property rights. You are cautioned not to place undue reliance on these forward-looking statements, which speak only as of the date hereof. Zogenix's actual future results may differ materially from its current expectations due to the risks and uncertainties inherent in its business. These risks include, but are not limited to: Zogenix's ability to successfully enforce its marketing exclusivities and intellectual property rights, and to defend its patents; Zogenix's reliance on its licensor to control enforcement proceedings for the Zohydro ER patents; the possibility that Zogenix and its licensor may be required to file lawsuits to defend the patent rights from challenges by companies seeking to market generic versions of Zohydro ER, and the substantial costs associated with such lawsuits; the possible introduction of generic competition to Zohydro ER; the risk that Zogenix may not be able to raise sufficient capital when needed, or at all; and other risks detailed under "Risk Factors" and elsewhere in Zogenix's periodic reports and other filings made with the Securities and Exchange Commission from time to time. All forward-looking statements are qualified in their entirety by this cautionary statement, which is made under the safe harbor provisions of Section 21E of the Private Securities Litigation Reform Act of 1995, and Zogenix undertakes no obligation to revise or update this report to reflect events or circumstances after the date hereof.
