Law Firm Kirby McInerney LLP Investigating Potential Claims on Behalf of Cadence Pharmaceuticals, Inc. Stockholders

Kirby McInerney LLP is investigating potential claims against the Board of Directors of Cadence Pharmaceuticals, Inc. (“Cadence” or the “Company”) (NASDAQ: CADX) concerning the proposed acquisition of the Company by Mallinckrodt plc (“Mallinckrodt”) (NYSE: MNK). Under the terms of the definitive merger agreement, Cadence stockholders will receive $14.00 in cash for each share of Cadence owned, valuing the transaction at approximately $1.3 billion on a fully diluted basis.
