CAMBRIDGE, Mass. -- March 19, 2013

Zalicus Inc. (Nasdaq Global Market: ZLCS) today announced that preclinical
data showing the advantages of applying Zalicus’s state dependent screening
approach to identify novel calcium channel blockers for the treatment of pain
was presented on March 18 at the 4th Annual RSC/SCI Symposium on Ion Channels
as Therapeutic Targets Conference taking place from March 18-19, 2013 in
Cambridge, UK.

In a poster presentation entitled “Screening for State-Dependent Blockers of
Voltage Gated Calcium Channels,” Margaret S. Lee, PhD, Vice President of
Research & Translational Medicine at Zalicus, demonstrated the utility of
inactivation state screening to identify novel, potent, selective and
state-dependent calcium channel blockers with efficacy in animal models of
inflammatory and neuropathic pain.

“Rapid neuronal firing which occurs during chronic pathological pain results
in accumulation of voltage gated calcium channels in an inactivated state. By
specifically targeting this inactivated state of these channels, it may be
possible to broaden the therapeutic window, minimize adverse effects and
increase efficacy for these promising pain therapies,” said Dr. Lee.
“Comparative screening in our cell based assays for state dependent modulation
of ion channel function has resulted in the discovery of Z160 and Z944,
Zalicus’s two most advanced novel, first-in-class calcium channel blockers.
Both Z160 and Z944 have effectively demonstrated enhanced potency for their
respective targets in the inactivated state.”

About Z160 and N-type Calcium Channel Blockers

Z160 is a first-in-class, oral, state-dependent, selective N-type calcium
channel (Cav 2.2) blocker, designed to selectively target neuronal pain
signaling by modulating neurons that are undergoing high-frequency firing.
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. Additionally, clinical trials in over 200 subjects
have established Z160 as a safe and well tolerated drug candidate. 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 has advanced Z160 into two Phase 2a proof-of-concept
clinical studies in chronic neuropathic pain and plans to report top-line data
in late 2013.

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.
