or behavior or laboratory abnormality that interferes with ability to participate in the
study, may increase the risk associated with study participation or investigational product
administration, or may interfere with the interpretation of study results and, in the
judgment of the investigator, would make the patient inappropriate for entry into this
study.

History of seizure or any condition that may predispose to seizure (eg, prior cortical
