Assuming Z944 successfully completes the MAD study, Z944 could enter Phase 2 clinical development in the first quarter of 2013. “I am encouraged by the continued progress the Zalicus team is making in advancing the development of our calcium channel blocker programs, including Z944 our T-type calcium channel blocker and Z160, our N-type calcium channel blocker which is poised to enter Phase 2a clinical trials in neuropathic pain later in the third quarter of 2012," commented Mark H.N.
