E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To develop a population pharmacokinetic model of levetiracetam during pregnancy. After the study, this model could be used to propose dose adjustments to maintain stable concentrations in pregnant women throughout pregnancy. |
la pharmacocinétique du Lévétiracétam pendant la grossesse |
|
E.2.2 | Secondary objectives of the trial |
- Describe placental transfer during childbirth and during a medical termination of pregnancy - Explain the interindividual variability of maternal pharmacokinetics and transplacental passage of Levetiracetam. - Link the concentration and its variation in the individual to the effects of treatment
|
- Décrire le passage transplacentaire à l’accouchement et au cours d’interruption médicale de grossesse - Expliquer la variabilité interindividuelle de la pharmacocinétique maternelle et du passage transplacentaire du Lévétiracétam. - Relier la concentration et sa variation chez l’individu aux effets du traitement

E.5 End points |
E.5.1 | Primary end point(s) |
Levetiracetam pharmacokinetics in pregnancy (Levetiracetam concentrations as a function of time) |
la pharmacocinétique du Lévétiracétam pendant la grossesse (Concentrations de lévétiracétam en fonction du temps) |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
At delivery |
A l'accouchement |
|
E.5.2 | Secondary end point(s) |
1) Levetiracetam pharmacokinetics in pregnancy: Percentage of inter-individual variability in clearance or volume explained by a covariate (weight, serum creatinine, co-administration of other antiepileptics). 2) Exposure ratio 3) Link between levetiracetam concentrations and effects: - correlate the evolution of the concentrations in the woman (value in the woman whose treatment is balanced before the pregnancy minus the value when she is pregnant) to the effectiveness (number of crises that the patient did). - tolerance: presence or absence of clinical and biological abnormalities occurring in pregnant women and children.
|
1) Expliquer la variabilité interindividuelle de la clairance d’élimination par d’autres facteurs tels que le poids, la créatininémie, la co-administration d’autres antiépileptiques. 2) Estimation du passage transplacentaire des antiépileptiques comme un ratio d’exposition entre la mère et le fÅ“tus 3) Corréler l’évolution des concentrations chez la femme (valeur chez la femme dont le traitement est équilibré avant la grossesse versus valeur lorsqu’elle est enceinte) à : - l’efficacité (nombre de crises que la patiente aura faites). - la tolérance : anomalies cliniques et biologiques survenant chez la femme enceinte et chez le nouveau-né |
