Epilepsy combo therapy shows promise in small trial
NCT ID NCT01345058
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether adding lacosamide (Vimpat) to a low dose of levetiracetam works better than a high dose of levetiracetam alone for controlling seizures. Fifty-six adults with epilepsy who had seizures on low-dose levetiracetam took part. The main goal was to see how many people stayed seizure-free for six months.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- lacosamide (Vimpat) and levetiracetam
- What this could lead to
- If successful, this could offer a more effective way to control seizures for people whose current medication isn't working well enough.
- What could go wrong
- This is a small, completed Phase 3 trial with only 56 participants, so results may not apply to everyone. Adding another drug also increases the risk of side effects.
