BRUSSELS, BELGIUM--(Marketwire - June 24, 2008) - UCB announced today headline results based on first-line analyses of its Phase IIa clinical trial with lacosamide to treat fibromyalgia syndrome. The initial results from this proof of concept study showed activity of lacosamide in fibromyalgia syndrome but require further analysis. A decision to start Phase IIb will be made by the end of the year. This lacosamide trial was randomized, placebo-controlled and double- blind to assess efficacy and safety of 400mg/day lacosamide tablets in patients suffering from signs and symptoms associated with fibromyalgia syndrome (FMS). This trial was designed to establish a signal to provide justification for further clinical development of lacosamide in FMS.
