General information about the trial
|
|||
Main objective of the trial |
To evaluate the safety and tolerability of the Levetiracetam IV 15-minute infusion administered every 12 hours, either as adjunctive treatment or monotherapy in children (4 to 16 years old) with epilepsy (except status epilepticus), either after switching from the equivalent LEV oral dose administration or as a new antiepileptic treatment.
|
||
Protection of trial subjects |
Adequate information was provided to the subject’s parents/legally acceptable representative in both oral and written form and consent was obtained from the parents/legally acceptable representative in writing prior to performance of any study specific procedure. In addition, it was recommended that the subject’s assent was also obtained, according to the child’s age/competence and the IEC/IRB requirements.

Arm description |
Intravenous 100 mg/mL, twice a day, maximum of 4 days. Subjects on oral levetiracetam at study entry receive the same intravenous (IV) dosage (mg-for-mg) to their oral dose. Dosage for subjects not on levetiracetam at study entry was based on weight: if <50 kg, the dose was 20 mg/kg/day (10 mg/kg/day twice daily); if weight ≥ 50 kg, the dose of levetiracetam intravenous (LEV IV) was 1000 mg/day (500 mg twice daily). | ||||||

| Notes [1] - No statistical analyses have been specified for this primary end point. It is expected there is at least one statistical analysis for each primary end point. Justification: The primary objective was to evaluate the safety and tolerability of the LEV IV 15-minute infusion administered every 12 hours, either as adjunctive treatment or monotherapy in children with epilepsy, either after switching from the equivalent LEV oral dose administration or as a new antiepileptic treatment. The safety profile of levocetirizine was summarized descriptively across several safety variables. Therefore, no inferential statistics were performed in this safety study. |

Substantial protocol amendments (globally) |

| Were there any global substantial amendments to the protocol? Yes | |||
Date |
Amendment |
||
04 May 2007 |
Clarification of the procedure for the administration of Levetiracetam (LEV) and of the number of mandatory infusion days. |
||
01 Jun 2007 |
Allowed for the adjustment of the LEV dose for subjects with moderate renal insufficiency, based on their CLCR value (compliance with French Competent Authorities). |
||
04 Apr 2008 |
Clarified the exclusion criterion for clinically significant acute or chronic illness and deleted the exclusion criteria for intake of 2 or more concomitant AEDs as well as vigabatrine.
Revised the schedule of PK assessment. The predose time point was replaced by a time point at 3 to 10 minutes after the start of the infusion.
Some logistical aspects of the study procedures were revised in order to facilitate the recruitment of subjects. |
||
18 Sep 2008 |
Clarified the objectives following the 16 May 2008 teleconference with the FDA, confirming that the main goal of the study was safety and tolerability of the use of LEV IV in pediatrics, with a lesser emphasis on PK.
This amendment also provided for the addition of FDA requests:
- Approximately one half of the subjects exposed to at least 3 consecutive LEV IV doses
- At least one third of the subjects should be in the high-dose range (≥40mg/kg/day)
Additionally, this amendment provided an addition of an exclusion criterion: “The subject presents current depressive symptoms, current suicidal ideation and/or behavior.” |
||
12 Nov 2009 |
Clarified the use of local laboratory results for the evaluation of subjects’ eligibility, and updated study team members’ information. |
