Levetiracetam Versus Standard Antiepileptic Drugs (Carbamazepine and Valproate) Used as Monotherapy in Patients With Newly Diagnosed Epilepsy

This study has been completed.
Sponsor:
Information provided by (Responsible Party):
UCB Pharma
ClinicalTrials.gov Identifier:
NCT00175903
First received: September 9, 2005
Last updated: March 12, 2015
Last verified: March 2015
  Purpose
Study N01175 was to compare overall effectiveness (efficacy and safety) of levetiracetam (LEV) versus the 2 older antiepileptic drugs (AEDs), sodium valproate extended release (VPA-ER) and carbamazepine controlled release (CBZ-CR) in the treatment of subjects with newly diagnosed epilepsy.

Condition Intervention Phase
Epilepsy Drug: Levetiracetam Drug: Carbamazepine Controlled Release (CBZ-CR) Drug: Valproate Extended Release Phase 3

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: A Therapeutic Confirmatory, Open-label, Multi-center, Randomized 2 Parallel Groups, Community-based Trial Studying the Efficacy and Safety of Levetiracetam (1000 to 3000 mg/Day Oral Tablets 250-500 mg b.i.d.) Compared to Sodium Valproate (1000 to 2000 mg/Day Oral ER Tablets 300-500 mg b.i.d.) and Carbamazepine (600 to 1600 mg/Day Oral CR Tablets 200-400 mg b.i.d.) as Monotherapy in Subjects With Newly Diagnosed Epilepsy.

Primary Outcome Measures:
  • Time to withdrawal from study medication (starting at V1) as a measure of combined efficacy and safety [ Time Frame: Visit 1 to End of Study (approximately 52 weeks) ]

Secondary Outcome Measures:
  • The time to withdrawal comparing Levetiracetam versus the older Antiepileptic Drugs based on the subset of subjects whose best recommended treatment was Carbamazepine Controlled Release or Sodium Valproate Extended Release [ Time Frame: Visit 1 to End of Study (approximately 52 weeks) ]
  • The retention rate after 6 months comparing Levetiracetam versus the older Antiepileptic Drugs [ Time Frame: Visit 1 to Visit 4 (approximately 26 weeks) ]
  • The retention rate after 12 months comparing Levetiracetam versus the older Antiepileptic Drugs [ Time Frame: Visit 1 to Visit 5 (approximately 52 weeks) ]
  • The retention rate after 6 months comparing Levetiracetam versus older Antiepileptic Drugs based on the subset of subjects whose best recommended treatment was Carbamazepine Controlled Release or Sodium Valproate Extended Release [ Time Frame: Visit 1 to Visit 4 (approximately 26 weeks) ]
  • The retention rate after 12 months comparing Levetiracetam versus older Antiepileptic Drugs based on the subset of subjects whose best recommended treatment was Carbamazepine Controlled Release or Sodium Valproate Extended Release [ Time Frame: Visit 1 to Visit 5 (approximately 52 weeks) ]
  • Seizure freedom at 6 months comparing Levetiracetam versus older Antiepileptic Drugs [ Time Frame: Visit 1 to Visit 4 (approximately 26 weeks) ]
  • Seizure freedom at 12 months comparing Levetiracetam versus older Antiepileptic Drugs [ Time Frame: Visit 1 to Visit 5 (approximately 52 weeks) ]
  • Seizure freedom at 6 months comparing Levetiracetam versus older Antiepileptic Drugs based on based on the subset of subjects whose best recommended treatment was Carbamazepine Controlled Release or Sodium Valproate Extended Release [ Time Frame: Visit 1 to Visit 4 (approximately 26 weeks) ]
  • Seizure freedom at 12 months comparing Levetiracetam versus older Antiepileptic Drugs based on based on the subset of subjects whose best recommended treatment was Carbamazepine Controlled Release or Sodium Valproate Extended Release [ Time Frame: Visit 1 to Visit 5 (approximately 52 weeks) ]
  • Time to first seizure comparing Levetiracetam versus older Antiepileptic Drugs [ Time Frame: Visit 1 to End of Study (approximately 52 weeks) ]
  • Time to first seizure comparing Levetiracetam versus older Antiepileptic Drugs based on the subset of subjects whose best recommended treatment was Carbamazepine Controlled Release or Sodium Valproate Extended Release [ Time Frame: Visit 1 to End of Study (approximately 52 weeks) ]
