 SP848 is an open-label study to evaluate long-term safety, tolerability, and efficacy in children with epilepsy treated with Lacosamide LCM oral solution syrup or LCM tablets as adjunctive therapy. In addition, the study is designed to provide continued availability of LCM to subjects who have completed the SP847 NCT00938431 study and to subjects who have discontinued from SP847 NCT00938431 and who, in the investigators opinion, would benefit from long-term administration of LCM.
