TimeToStop (TTS) Trial, A randomized controlled trial of cognitive consequences of early versus late antiepileptic drug withdrawal after pediatric epilepsy surgery

Primary Objective: To assess whether early postoperative AED withdrawal improves cognitive function compared to late withdrawal.Secondary objectives: * To confirm safety of earlier AED withdrawal; we will assess eventual seizure freedom, seizure…

Randomized, double-blind, double-dummy, placebo-controlled, four-way crossover single dose
study to determine the test-retest reliability of, and the effect of oral valproic acid, levetiracetam and
lorazepam on, cortical excitability measurements in healthy volunteers as measured by TMS-EEG and TMS-EMG.

Primary Objective- To investigate the ability of TMS-EEG measures to detect effects on cortical excitability of valproic acid, levetiracetam and lorazepam in healthy subjects- To investigate the ability of TMS-EMG measures to detect effects on…

Double-blind randomized trial comparing efficacy, safety and tolerance between Levetiracetam monotherapy and Valproic acid monotherapy in children with newly diagnosed epilepsy

The objectives of this multi-centre, double-blind, randomized, 2-parallelgroups study are to investigate the efficacy, safety and tolerability of levetiracetam (LEV) monotherapy 15-60mg/kg/day versus valproic acid (VPA) monotherapy 10-40mg/kg/day in…

A PROSPECTIVE, MULTINATIONAL, OPEN-LABEL, SINGLE-ARM, EXPLORATIVE STUDY TO EVALUATE THE TOLERABILITY AND EFFICACY OF LACOSAMIDE WHEN ADDED TO LEVETIRACETAM WITH WITHDRAWAL OF THE CONCOMITANT SODIUM CHANNEL BLOCKING ANTIEPILEPTIC DRUG IN SUBJECTS WITH UNCONTROLLED PARTIAL-ONSET SEIZURES

The primary objective of this study is to assess the overall effectiveness of LCM (optimizedwithin the range of 200mg/day to 600mg/day) when added to a stable dose of LEV (in thelabel range of 1000mg/day to 3000mg/day) with withdrawal of the…

Levetiracetam (Keppra®) in neonates

Objective: Primary objective: safety profile of LEV in neonates. Safety outcome parameters as liver, kidney and metabolic function, electrolytes, hemodynamic effects (heart rate/arrhythmia, arterial blood pressure/hypotension). Investigation of…

Pharmacokinetics of levetiracetam after rectal administration in healthy volunteers

Comparison of single-dose pharmacokinetics of levetiracetam after rectal versus oral administration at healthy volunteers.

A randomized, double-blind, two-way cross-over study to determine the effects of levetiracetam on corticospinal excitability in patients with treatment-controlled epilepsy, as measured by single and paired pulse TMS-EMG and TMS-EEG

- To evaluate effects of levetiracetam 2000 mg on single and paired pulse TMS-EMG and TMS-EEG in patients with epilepsy treated with mono-therapy levetiracetam, when compared to placebo (levetiracetam trough concentrations). - To evaluatethe effects…
