Zalicus Inc. (NASDAQ: ZLCS) today reported financial results for the second quarter ended June 30, 2012.

“During the first half of 2012 we made tremendous progress advancing our internal pipeline candidates including the initiation of a multiple ascending dose Phase 1 clinical study with Z944, our novel, oral, T-type calcium channel blocker and second Ion channel program to advance into clinical development,” commented Mark H.N. Corrigan, MD, President and CEO of Zalicus. “Looking forward to the third quarter of 2012 we are on-track to move Z160, our first-in-class treatment for neuropathic pain, into Phase 2a clinical trials and report top-line data results with Synavive.”

Financing Matters:

As of June 30, 2012, we had cash, cash equivalents, restricted cash and short-term investments of approximately $44.1 million compared to $52.5 million on March 31, 2012.

For the quarter ended June 30, 2012, revenue was $2.9 million compared to $1.8 million for the quarter ended June 30, 2011. The increase in revenue from the 2011 to the 2012 period was primarily due to increased Exalgo royalties from Covidien and increased collaboration revenue from Novartis. Zalicus recognized $1.3 million in royalty revenue from Covidien based on Exalgo sales for the quarter ended June 30, 2012. This represented a 12% increase in revenue from Exalgo compared to the first quarter of 2012.

For the quarter ended June 30, 2012, net loss was $10.3 million, or $0.09 per share, compared to a net loss of $11.3 million, or $0.11 per share, in the quarter ended June 30, 2011.

Research and development expenses were $9.9 million in the quarter ended June 30, 2012 compared to $9.0 million in the quarter ended June 30, 2011. The increase in R&D expense from the 2011 period to the 2012 period was primarily due to increased clinical development expenses related to Z160.

General and administrative expenses were $2.3 million in the quarter ended June 30, 2012 compared to $2.7 million for the quarter ended June 30, 2011. We expect our general and administrative expenses for the remainder of the year ending December 31, 2012 to be consistent with such expenses during 2011.
