- Subject has any ongoing Adverse Event (AE) in their long-term, open-label study that, in the opinion of the investigator, could jeopardize or would compromise the subject's ability to participate EP0060 or the subject meets any of the criteria for required withdrawal from the long-term open-label study

For prescription lacosamide (RxL) and initiating intravenous lacosamide (IIL) subjects, enrollment in EP0060 is not permitted if any of the following additional criteria are met:
