A Multicenter, Randomized, Controlled, Open-label Study to Evaluate the Cognitive Development Effects and Safety, and Pharmacokinetics of Adjunctive Rufinamide Treatment in Pediatric Subjects 1 to Less Than 4 Years of Age With Inadequately Controlled Lennox-Gastaut Syndrome

Child Behavior Checklist (CBCL) Total Problem T-scores at the End of 2-year Treatment Period

时间窗: End of Treatment Period (up to approximately Week 106)

CBCL: 99-item questionnaire measures specific behavioral problems or developmental delays, answered by a parent/legal guardian or suitable caregiver. Each item were rated using 3-point scale (0=Not True, 1=Somewhat/Sometimes True, 2=Very True/ Often True) to indicate how often or typical the behavior was. The 99 items were combined to yield scores for 8 problem area scales (emotionally reactive, anxious/depressed, somatic complaints, withdrawn, sleep problems, attention problems, aggressive behavior, and other problems) and 3 summary scores (internalizing, externalizing, and total problems). Total Problem score was sum of all the problem areas plus 1 additional item, ranging from 0 to 198. Total raw scores are converted to t-scores with mean of 50 and standard deviation (SD) of 10. T-scores were standardized test scores that indicate same degree of elevation in problems relative to the normative sample of peers. Higher scores were indicative of more problems.
