Cubist Announces Exclusive Option To Acquire Adynxx

February 25, 2013


Lexington, Mass., and San Francisco, Calif. February 25, 2013Cubist Pharmaceuticals, Inc. (NASDAQ: CBST) and Adynxx, Inc. announced today that they have entered into an option agreement under which Cubist has the exclusive right to acquire Adynxx following the data readout of Adynxx’s Phase 2 trial for its lead product candidate, AYX1.

Adynxx, a privately held, clinical-stage pharmaceutical company focused on developing novel analgesic therapies, is studying AYX1 as a potential treatment for the reduction of acute pain and prevention of persistent and chronic pain following surgery. The current Phase 2 study is designed to assess the ability of a single administration of AYX1 at the time of unilateral total knee arthroplasty to reduce movement evoked pain, as well as improve the rate and extent of functional recovery. AYX1 targets EGR1 which is a key transcription factor in the establishment of pain that is rapidly induced after painful stimuli or injury.

“This option agreement with Adynxx is an example of our disciplined efforts to expand our acute care pipeline, consistent with our Building Blocks of Growth goals,” said Steven Gilman, Executive Vice President, Research & Development and Chief Scientific Officer of Cubist. “We are impressed with the pre-clinical and Phase 1 results to date of AYX1 and believe this program has the potential to become an important, new therapy that may help patients to address the significant issue of post-surgical and chronic pain. We are pleased to continue to advance AYX1 through this mutually beneficial agreement which provides Cubist exclusive rights to acquire Adynxx in the future.”

Added Rick Orr, Chief Executive Officer of Adynxx, “We believe AYX1 has the potential to revolutionize the treatment of post-surgical pain. Based on the growing need for new pain therapies that offer more than temporary symptom relief, Adynxx is committed to developing AYX1 as rapidly and robustly as possible. Given Cubist’s proven expertise in the hospital setting, this agreement maximizes our chances of bringing this transformative therapy to market.”

Pursuant to the agreement, Cubist will pay Adynxx to secure the option right. Cubist will fund the consideration with cash on hand. If Cubist exercises its right to acquire Adynxx, Cubist will make additional payments to the Adynxx stockholders.
