Trial Outcomes & Findings for Clobazam in Patients With Lennox-Gastaut Syndrome (NCT NCT00518713)
NCT ID: NCT00518713
Last Updated: 2012-02-09
Results Overview
Number of drop seizures (average per week) was obtained from seizure diaries. The average drop in seizures per week for patients who did not complete the maintenance period was calculated based on the time from the beginning of the maintenance period to date of withdrawal.

OTHER_PRE_SPECIFIED outcome
Timeframe: 4-week baseline period and the 12-week maintenance periodThis outcome measure evaluated the percent reduction (average per week) in non-drop Seizures. Non-drop seizures were other seizures not meeting the drop seizure definition. Drop seizures were defined as a drop attack or spell (atonic, tonic or myoclonic) involving the entire body, trunk, or head that led to a fall, injury, slumping in chair, or head hitting surface or that could have led to a fall or injury, depending on the position of the patient at the time of the attack or spell.
