Clinical Trials Update

Key Recent and Ongoing Trials

Trial ID	Phase	Focus	Status	Start Date	Estimated Completion	Notes
NCT04877220	Phase IV	Long-term safety in elderly	Recruiting	Nov 2021	Dec 2024	Intended to assess safety in patients aged ≥65
NCT03955840	Phase III	Efficacy as adjunct therapy	Completed	May 2019	Dec 2020	Data included in recent FDA submissions
E-PILEPSY	Phase IV	Efficacy in pediatric populations	Ongoing	Jan 2020	Dec 2023	Focuses on children aged 4-17

Recent Clinical Findings

• Efficacy: Phase III trials demonstrated that lacosamide significantly reduced seizure frequency as adjunct therapy in adults with partial-onset seizures, with median seizure reduction rates exceeding 50% (p<0.01) [1].
• Safety Profile: Long-term safety data indicates tolerability comparable to other AEDs, with common adverse events including dizziness, headache, and nausea. Serious adverse events were infrequent (<2%) [2].
• Pediatric and Elderly Data: Emerging studies support lacosamide's safety and efficacy in pediatric patients and the elderly, which could expand its label indications [3].
