This is a study to determine whether a combination of low dose lacosamide and levetiracetam is more effective than high dose levetiracetam in patients who have failed low dose levetiracetam.

Condition Intervention Phase
Epilepsy Drug: lacosamide Drug: levetiracetam Phase 3

Study Type: Interventional
Study Design: Allocation: Non-Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: Open Label Trial of Add on Lacosamide Versus High Dose Monotherapy in Patients With a Seizure Disorder

Further study details as provided by Jong Woo Lee, Brigham and Women's Hospital:

Primary Outcome Measures:
  • Percentage of Participants Achieving Six Month Seizure Freedom [ Time Frame: 6 Months ]
    Seizure freedom is defined as having no seizures and was evaluated in the 6 month period after receiving the drug.

Secondary Outcome Measures:
  • Number of Seizure-Free Days [ Time Frame: 6 Months ]
  • Time to First Seizure After Therapeutic Dose is Reached [ Time Frame: 6 Months ]
    Time in days until the first seizure after the therapeutic dose is reached occurs.

  • Retention Rate [ Time Frame: 6 Months ]
    Retention rate is defined as the percentage of participants who remained on the study drug after study completion.

  • Number of Participants With Treatment-Emergent Adverse Events (TEAE) [ Time Frame: 6 Months ]
    An Adverse Event (AE) is defined as any untoward medical occurrence (side effect) in a clinical investigation participant administered a drug; it does not necessarily have to have a causal relationship with this treatment. A TEAE is defined as an adverse event that occurs after receiving the drug.

Enrollment: 56

Study Completion Date: October 21, 2014
Primary Completion Date: February 15, 2014 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Lacosamide + Low-Dose Levetiracetam
Participants received lacosamide 50 mg twice a day for one week followed by 100 mg twice daily added to low dose levetiracetam ≤1500 mg/day (polytherapy) for 6 months in patients with breakthrough seizures on low-dose levetiracetam.
Drug: lacosamide

Lacosamide maximum of 200 mg/day, to be titrated as follows:

  • Week 1: 50 mg twice a day
  • Beginning Week 2: 100 mg twice a day.
Other Name: Vimpat
Drug: levetiracetam
Low dose ≤1500 mg/day, High dose >1500 mg/day
Control Group (High-Dose Levetiracetam)
Historical chart review of patients whose dose of levetiracetam was raised to high dose levetiracetam >1500 mg/day (monotherapy) after a breakthrough seizure. No intervention was administered in the study.
Drug: levetiracetam
Low dose ≤1500 mg/day, High dose >1500 mg/day


Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  1. Adults age 18 or older
  2. Determined to have had at least two partial seizures by an epilepsy specialist, or to have had a single partial seizure with clinical and/or laboratory evidence of a high seizure recurrence risk
  3. Monotherapy on levetiracetam less than or equal to 1500 mg/day for at least two weeks
  4. Breakthrough seizure while on stable dose (>5 days) of levetiracetam monotherapy regimen, not due to provocative factors (e.g. hypoglycemia, head trauma, missed medications)

Exclusion Criteria:

  1. Clinical suspicion of nonepileptic psychogenic seizures or idiopathic generalized epilepsy
  2. Pregnant, child-bearing age not using contraception, or breast feeding
  3. Medical contraindication to adding lacosamide
  4. History of antiepileptic drug (AED) polytherapy
  5. Presence of a vagus nerve stimulator
  6. Creatinine clearance of less than 50 mL/min
  7. Blood pressure instability: pulse <50 or >100, systolic blood pressure (SBP) <50 or >180, clinically significant electrocardiogram (EKG) abnormality
  8. History of significant drug rash or anaphylactic reaction with antiepileptic drug
  9. Patients with progressive lesions (e.g. brain tumors)
