DUBLIN & SAN DIEGO--(BUSINESS WIRE)--Feb. 11, 2014-- Mallinckrodt plc (NYSE: MNK), a leading global specialty pharmaceuticals company, and Cadence Pharmaceuticals, Inc. (NASDAQ: CADX) today announced that they have entered into a definitive agreement under which a subsidiary of Mallinckrodt plc will commence a tender offer to acquire all outstanding shares of Cadence Pharmaceuticals, Inc. for $14.00 per share in cash or approximately $1.3 billion on a fully diluted basis, which represents a 32% premium to the trailing 30-trading-day volume weighted average price (VWAP) of $10.62 per share for Cadence Pharmaceuticals, Inc.

Subject to customary terms and conditions, the parties expect the transaction to close in mid- to late-March. Mallinckrodt expects the acquisition will be immediately accretive to its fiscal year 2014 adjusted diluted earnings per share, and significantly accretive to its fiscal year 2015 adjusted diluted earnings per share.

Cadence Pharmaceuticals is a biopharmaceutical company focused on commercializing products principally for use in the hospital setting. The company’s product OFIRMEV^® (acetaminophen injection) is a proprietary intravenous formulation of acetaminophen for the management of mild to moderate pain, the management of moderate to severe pain with adjunctive opioid analgesics and the reduction of fever. Since its introduction, OFIRMEV has experienced strong growth, and in a press release issued January 13, 2014, Cadence reported that it expects net revenues of $110.5 million for OFIRMEV in calendar year 2013 compared to 2012 reported OFIRMEV net product revenues of $50.1 million. OFIRMEV is currently on formulary in more than 2,350 U.S. hospitals and has been used to treat an estimated 6 to 7 million patients since its launch in January 2011 A New Drug Submission for the product has been approved by Health Canada.

This transaction accelerates growth in Mallinckrodt’s Specialty Pharmaceuticals segment in key ways. First, the company adds another powerful growth product, OFIRMEV, to the segment’s robust portfolio of core controlled substance generics and its growing roster of brands like EXALGO^®, Gablofen^®, PENNSAID^® 2% and, if approved, XARTEMIS™ XR and longer term, MNK-155. Additionally with the strong presence Cadence has established in the adjacent hospital market, the acquisition adds another potential growth dimension for the segment, providing Mallinckrodt an opportunity to expand the company’s reach and penetration in this important channel.

“The acquisition of Cadence Pharmaceuticals is consistent with our goal of becoming a leading global specialty pharmaceuticals company,” said Mark Trudeau, Chief Executive Officer and President of Mallinckrodt. “OFIRMEV’s growth is driven by an expanding base of physicians who are prescribing the product for an increasing number of surgical patients, and we believe the product will be an outstanding addition to the brands component of Mallinckrodt’s Specialty Pharmaceutical segment. We have been impressed with the strong relationships that Cadence’s commercial organizations have established with customers in the hospital channel and are excited by the opportunity to build on these relationships to expand our platform in this area. We believe Mallinckrodt is well-positioned to further accelerate the trajectory of OFIRMEV and realize the full value of this product in the marketplace.”

“We are very proud of what our employees have accomplished, and in particular the very strong growth we have achieved with OFIRMEV,” said Ted Schroeder, President and Chief Executive Officer of Cadence Pharmaceuticals. “The relationships we’ve established with our customers and the benefits the drug has provided to millions of patients across the U.S. have contributed to the strong year-on-year growth we’ve seen for the product since launch. We believe Mallinckrodt is a natural fit to provide the resources and expertise that can expand patient access for OFIRMEV. Additionally, this transaction will provide Cadence shareholders with a strong return on their investment.”

ABOUT OFIRMEV^® (ACETAMINOPHEN) INJECTION

OFIRMEV (acetaminophen) injection (1000 mg / 100 mL, 10 mg / mL; for intravenous use only), Cadence Pharmaceutical’s 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 two years of age.

Important Safety Information

RISK OF MEDICATION ERRORS AND HEPATOTOXICITY

Take care when prescribing, preparing, and administering OFIRMEV injection to avoid dosing errors which could result in accidental overdose and death.

OFIRMEV contains acetaminophen. Acetaminophen has been associated with cases of acute liver failure, at times resulting in liver transplant and death. Most of the cases of liver injury are associated with the use of acetaminophen at doses that exceed the recommended maximum daily limits, and often involve more than one acetaminophen-containing product.

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. Rarely, acetaminophen may cause serious skin reactions such as acute generalized exanthematous pustulosis (AGEP), Stevens-Johnson Syndrome (SJS), and toxic epidermal necrolysis (TEN), which can be fatal. Discontinue OFIRMEV immediately if symptoms associated with allergy or hypersensitivity occur, or at the first appearance of skin rash. 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 with postsurgical pain. OFIRMEV is approved for use in patients ≥ 2 years of age. Do not exceed the recommended maximum daily dose of OFIRMEV. OFIRMEV should be administered only as a 15-minute infusion.
