Business Wire

CAMBRIDGE, Mass. -- June 4, 2013

Zalicus Inc. (Nasdaq Capital Market: ZLCS) a biopharmaceutical company that
discovers and develops novel treatments for patients suffering from pain,
today announced that it is advancing Z944, its novel oral T-type calcium
channel blocker, into further clinical development in the third quarter of
2013. The planned Phase 1b study is a state-of-the-art experimental clinical
model utilizing Laser-Evoked Potentials (LEP) to provide an efficient and
objective assessment of the activity of Z944 in an induced neuropathic pain
state. Results from the LEP study can further inform Zalicus’s development
plans for Z944 in a variety of potential indications.

The LEP clinical model is a type of experimental medicine study designed to
provide both objective and subjective data on a drug’s ability to modulate
pain signaling. In this model electrical voltage fluctuations evoked by laser
thermal stimulation are quantified with vertex-Electroencephalography (EEG) in
addition to a subject-reported pain score. Many currently approved and
emerging pain drugs have been evaluated using the LEP model, providing the
ability to benchmark the efficacy of Z944 against other therapies.

"T-type calcium channels are known to be widely implicated in the frequency
and intensity of pain signals, and we believe Z944 is the most advanced T-type
calcium channel blocker currently in clinical development,” commented Mark
H.N. Corrigan, MD, President and CEO of Zalicus. “The Laser Evoked Potential
experimental model is an efficient way to gather response data in a clinical
setting to further support the potential efficacy of Z944 in pain and inform
future development decisions.”

About Z944 and T-type Calcium Channel Blockers

Z944 is a novel, oral, state-dependent, selective T-type calcium channel
blocker that has demonstrated preclinical efficacy in multiple inflammatory
pain models. T-type calcium channels have been recognized as key targets for
therapeutic intervention in a broad range of cell functions and have been
implicated in pain signaling. Zalicus completed Phase 1 single and multiple
ascending dose clinical studies evaluating the safety and tolerability of Z944
in late 2012 and plans to continue further clinical development during 2013.
