Cadence Pharmaceuticals Announces Settlement of OFIRMEV® (Acetaminophen) Injection Patent Litigation with Perrigo Company

SAN DIEGO, Nov. 28, 2012 /PRNewswire/ -- Cadence Pharmaceuticals, Inc. (Nasdaq: CADX) today announced that it has entered into settlement and license agreements with Perrigo Company (Nasdaq: PRGO; TASE), and its subsidiary, Paddock Laboratories, LLC, to resolve pending patent litigation involving OFIRMEV® (acetaminophen) injection.

The settlement agreement includes a stipulation by the parties requesting dismissal with prejudice of the lawsuit filed by Cadence in the U.S. District Court for the District of Delaware relating to the Abbreviated New Drug Application, or ANDA, filed by Paddock with the U.S. Food and Drug Administration for a generic version of OFIRMEV® (acetaminophen) injection.  Litigation remains ongoing against Exela Pharma Sciences, LLC, Exela PharmaSci, Inc. and Exela Holdings, Inc.

Under the license agreement, Perrigo has been granted the exclusive right of first refusal to negotiate an agreement with Cadence to market an authorized generic version of OFIRMEV (i.e., a generic version marketed under Cadence's New Drug Application) in the U.S., in the event that Cadence elects to launch an authorized generic version of the product. Additionally, Cadence has granted Perrigo the non-exclusive right to market a generic intravenous acetaminophen product in the U.S. under Perrigo's ANDA, after December 6, 2020, or earlier under certain circumstances. Currently, Cadence has listed two Orange Book patents covering OFIRMEV, the last of which, U.S. Patent No. 6,992,218, will expire on June 6, 2021, or December 6, 2021, if pediatric exclusivity is granted.

The license agreement also provides that, if the parties enter into an agreement for Perrigo to market an authorized generic version of OFIRMEV, during the license period, Perrigo would purchase the product exclusively from Cadence. Cadence would receive product costs plus an administrative fee, as well as a royalty payment based on the net profits achieved by Perrigo from the sale of the authorized generic product. Other details of the settlement are confidential, and the agreements are subject to submission to the Federal Trade Commission and the U.S. Department of Justice. The settlement and license agreements will become effective upon the entry by the U.S. District Court for the District of Delaware of an order dismissing with prejudice the litigation with respect to Perrigo.

"This settlement validates our confidence in the integrity of the patents covering OFIRMEV," said Ted Schroeder, President and CEO of Cadence. "We believe that OFIRMEV is an important medication for managing pain and fever in hospitalized patients, and we look forward to years of continued growth in sales of this product."

About OFIRMEV® (Acetaminophen) Injection

OFIRMEV (acetaminophen) injection (1000 mg / 100 mL, 10 mg / mL; for intravenous use only), Cadence Pharmaceuticals' proprietary intravenous formulation of acetaminophen, is indicated for the management of mild to moderate pain, the management of moderate to severe pain with adjunctive opioid analgesics, and the reduction of fever. The FDA approval of OFIRMEV was based on data from clinical trials in approximately 1,020 adult and 355 pediatric patients. These trials included two studies evaluating the safety and effectiveness of OFIRMEV in the treatment of pain, and one study evaluating OFIRMEV in the treatment of fever. The effectiveness of OFIRMEV for the treatment of acute pain and fever has not been studied in pediatric patients less than 2 years of age.

Important Safety Information

Do not exceed the maximum recommended daily dose of acetaminophen. Administration of acetaminophen by any route in doses higher than recommended may result in hepatic injury, including the risk of severe hepatotoxicity and death. OFIRMEV is contraindicated in patients with severe hepatic impairment, severe active liver disease or with known hypersensitivity to acetaminophen or to any of the excipients in the formulation. Acetaminophen should be used with caution in patients with the following conditions: hepatic impairment or active hepatic disease, alcoholism, chronic malnutrition, severe hypovolemia, or severe renal impairment. OFIRMEV should be administered only as a 15-minute intravenous infusion. Discontinue OFIRMEV immediately if symptoms associated with allergy or hypersensitivity occur. Do not use in patients with acetaminophen allergy. The most common adverse reactions in patients treated with OFIRMEV were nausea, vomiting, headache, and insomnia in adult patients and nausea, vomiting, constipation, pruritus, agitation, and atelectasis in pediatric patients. The antipyretic effects of OFIRMEV may mask fever in patients treated for post-surgical pain.

You are cautioned not to place undue reliance on these forward-looking statements, which speak only as of the date hereof. Cadence's actual future results may differ materially from Cadence's current expectations due to the risks and uncertainties inherent in its business. These risks include, but are not limited to: Cadence's dependence on the successful commercialization of OFIRMEV, which is currently the company's only product, including its ability to achieve broad market acceptance and generate revenues from sales of OFIRMEV; Cadence's ability to successfully enforce its marketing exclusivities and intellectual property rights, and to defend the patents covering OFIRMEV, including in current patent litigation with Exela Pharma Sciences, LLC, Exela PharmaSci, Inc. and Exela Holdings, Inc., or collectively, Exela; the potential that Cadence may be required to continue patent litigation for substantial lengths of time, file additional lawsuits to defend its patent rights from challenges by Exela or other companies that may submit ANDAs for generic versions of OFIRMEV, and the substantial costs associated with such lawsuits; the potential that the United States Patent and Trademark Office, or USPTO, may not prevail in a lawsuit filed against it earlier this year by Exela in the United States District Court for the Eastern District of Virginia, in which Exela seeks a reversal of the USPTO's decision to refuse to act on a petition by Exela to vacate the USPTO's April 2003 order reviving the international application for U.S. Patent No. 6,992,218; the potential that the USPTO may grant an ex parte request for the reexamination of U.S. Patent No. 6,028,222, and that, as a result of such reexamination, claims in that patent may be invalidated or narrowed in scope; the potential introduction of generic competition to OFIRMEV in the event Cadence is unsuccessful in current or future patent litigation; Cadence's dependence on its licensors for the maintenance and enforcement of its intellectual property rights; the potential product liability exposure associated with pharmaceutical products such as OFIRMEV and other products Cadence may in-license or acquire; Cadence's ability to ensure an adequate and continued supply of OFIRMEV to meet anticipated market demand; and the risk that Cadence may not be able to raise sufficient capital when needed, or at all; and other risks detailed under "Risk Factors" and elsewhere in Cadence's periodic reports and other filings made with the SEC from time to time.
