Cubist Pharmaceuticals, Inc. (NASDAQ: CBST) and Adolor Corporation (NASDAQ: ADLR) today announced that they have signed a definitive agreement under which Cubist will acquire all of the outstanding shares of Adolor for $4.25 per share in cash, or approximately $190 million on a fully-diluted basis, net of Adolor’s third quarter 2011 cash balance. In addition to the upfront cash payment, each Adolor stockholder will receive one Contingent Payment Right (CPR), entitling the holder to receive additional cash payments of up to $4.50 for each share they own if certain regulatory approvals and/or commercialization milestones for ADL5945 are achieved. The total transaction is valued at up to $415 million, net of Adolor’s third quarter 2011 cash balance, and is expected to be accretive in 2012.
Under the agreement, Cubist will commence a tender offer to purchase all of the outstanding shares of Adolor for the upfront cash payment and a CPR. The transaction, which has been unanimously approved by the Boards of Directors of both companies, is expected to close in the fourth quarter of 2011.
Adolor markets ENTEREG® (alvimopan), the first and only FDA-approved therapy to accelerate the time to upper and lower gastrointestinal recovery following partial large or small bowel resection surgery with primary anastomosis. ENTEREG is an oral, peripherally-acting mu opioid receptor antagonist. Cubist, with its focus on addressing acute care and hospital needs, will leverage its existing commercial operations to promote ENTEREG. Launched in 2008, ENTEREG generated more than $25 million in U.S. sales in 2010 and $15.7 million through June 30, 2011. Cubist anticipates peak ENTEREG sales of over $100 million annually.
Adolor’s lead development program is ADL5945, an oral, peripherally-restricted mu opioid receptor antagonist. It is currently in development for the treatment of chronic opioid induced constipation (OIC), a growing, multi-billion dollar, currently underserved market. Adolor announced positive Phase 2 data for ADL5945 in August 2011 and Phase 3 trials are expected to be initiated in 2012. Cubist plans to retain certain U.S. and specialty rights while seeking a partner to assist with ex-U.S. and primary care commercialization.“This transaction is an excellent strategic fit for Cubist and the latest milestone in what has been a transformational year for the company,” said Cubist President and Chief Executive Officer Michael Bonney. “ENTEREG is a first-in-class therapy with strong growth potential, and we believe our experienced sales force and strong commercial platform will realize the potential of this important hospital product. With the addition of ADL5945, Cubist will have a truly outstanding late-stage pipeline with three strong candidates addressing significant markets. We are excited about the acquisition of Adolor and believe it will deliver significant value to our shareholders, hospital customers, and patients.”
