(NASDAQ: ZLCS), a biopharmaceutical company that discovers and develops novel treatments for patients suffering from pain, today announced that Z160, its first-in-class, oral, state-dependent, selective N-type calcium channel (Cav 2.2) blocker in Phase 2 clinical development for chronic neuropathic pain, has been chosen by Windhover as one of the Top 10 Neuroscience Projects to Watch. Mark Corrigan, MD, CEO of Zalicus, will provide a summary of Z160 during his presentation at the Windhover 2012 Therapeutic Area Partnership meeting being held at the Westin Copley Place Boston at 1:30 p.m. ET on Thursday, November 29, 2012 during the Top 10 Neuroscience Projects to Watch session.

"We are delighted that Z160 has been selected as a Top 10 Project to Watch,” commented Mark H.N. Corrigan, MD, President and CEO of Zalicus. “The lack of adequate pain control in patients with chronic neuropathic pain represents a significant unmet need and important opportunity for novel agents with improved tolerability, enhanced efficacy, and better long-term safety profiles. We look forward to providing further updates on the clinical development of Z160 over the coming months.”

Zalicus is currently advancing Z160, a first-in-class, oral, state-dependent, selective N-type calcium channel (Cav 2.2) blocker, through Phase 2a clinical development in chronic neuropathic pain. Z160 has demonstrated efficacy in multiple animal models of neuropathic and inflammatory pain, suggesting that it has the potential to treat a broad range of chronic pain conditions. In addition, Z160 was well tolerated in previously conducted clinical trials involving over 200 subjects. N-type calcium channels have been recognized as key targets in controlling pain because of their key role in transmitting pain through the spinal nerves to the brain.

Zalicus Inc. (Nasdaq: ZLCS) is a biopharmaceutical company that discovers and develops novel treatments for patients suffering from pain. Zalicus has a portfolio of proprietary clinical-stage product candidates targeting pain such as Z160 and Z944, and has entered into multiple revenue-generating collaborations with large pharmaceutical companies relating to other products, product candidates and drug discovery technologies.
