About this trial

This project focuses on anti-seizure medication (ASM) clearance and physiological factors determining blood concentrations in pregnant adult women with epilepsy and amounts of exposure to their unborn children and nursing infants.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Woman with epilepsy between the ages of 18-45 planning pregnancy or in the early first trimester of pregnancy.

Women with epilepsy ability to maintain a daily medical diary

Women with epilepsy ability to answer side effect questionnaires

Women with epilepsy currently being treated with lamotrigine (LTG) or levetiracetam (LEV) or oxcarbazepine (OXC)

Disqualifiers

Women with epilepsy having history of functional seizures.

Women with epilepsy history of other major medical illnesses including renal or hepatic disease, progressive cerebral disease,

Women with epilepsy who have inability to maintain a seizure and medication daily diary

Women with epilepsy with present or recent history of drug or alcohol abuse, or the use of any concomitant medications that interact with the ASM they are taking (lamotrigine, levetiracetam, oxcarbazepine).

Trial population

Participants to be mainly recruited from Neurology and OBGYN clinics.

Trial outcomes

Primary outcomes

1

Anti-Seizure Medication (ASM) Clearance

ASM Clearance will be calculated from measurements of lamotrigine, oxcarbazepine, and levetiracetam blood concentrations, serum creatinine and 24-hour urine collection (for levetiracetam), glucuronidated metabolite (for lamotrigine), steroid hormones, medication formulation and doses, time since recent doses, and participant weight.

Time frame
Through study completion, an average of 18 months.

Secondary outcomes

1

Seizure Frequency

Participants will keep a daily seizure diary throughout their participation in the study. The diary will be reviewed at each study visit.

Time frame
Through study completion, an average of 18 months.
2

Anti-seizure Medication (ASM) Side Effects

An ASM Side Effect Questionnaire will be administered and a neurologic examination will be performed at each study visit.

Time frame
Through study completion, an average of 18 months
3

Placental passage of Anti-Seizure Medications (ASM)

Maternal blood will be drawn and umbilical cord blood will be collected, for measurements of ASM concentrations for lamotrigine, oxcarbazepine, and levetiracetam.

Time frame
Through study completion, an average of 18 months
