Levetiracetam taken three times daily for adults with epilepsy

Evaluating Efficacy and Tolerability of Three Times Daily Levetiracetam in Epilepsy Patients

PHASE3 · King Saud University · NCT07490769

This study will try giving levetiracetam three times a day to adults with uncontrolled epilepsy who are already on high-dose levetiracetam to see if it increases seizure-free days compared with twice-daily dosing.

What this trial studies

This is a phase 3, interventional self-matched pre-post study in which each participant serves as their own control. Adults on levetiracetam monotherapy at high dose (1.5–3 g/day) with at least 12 months of documented use will have baseline seizure and safety data collected, then switch to three-times-daily oral dosing during the treatment period. Participants will keep a daily seizure diary and attend scheduled clinic visits for efficacy and safety monitoring. The primary outcome is change in seizure-free days, and adverse events and renal safety will also be recorded.

Who should consider this trial

Good fit: Adults (≥18 years) with uncontrolled epilepsy who have been on levetiracetam monotherapy at high dose (1.5–3 g/day) for at least 12 months and have had one or more unprovoked seizures in the past 6 months.

Not a fit: People who are pregnant, have significant renal impairment (CrCl <30 mL/min), are taking other antiepileptic drugs, or already have well-controlled seizures are unlikely to be eligible or to gain benefit from this dosing change.

Why it matters

Potential benefit: If successful, switching to three-times-daily dosing could increase seizure-free days and improve seizure control without adding other antiepileptic drugs.

How similar studies have performed: Most prior levetiracetam research uses twice-daily dosing and there is limited evidence that thrice-daily dosing is superior, so this dosing strategy is relatively untested in controlled settings.
