Further study details as provided by Novartis:

Primary Outcome Measures:
  • To detect a dose-response by measuring the percent change in seizure frequency of BGG492 from baseline to maintenance period. [ Time Frame: 28 days ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • To evaluate the efficacy of BGG492 compared to placebo as a change in seizure frequency from baseline period to maintenance period. [ Time Frame: 28 days ] [ Designated as safety issue: No ]
  • Responder rate: analysis of patients with a 50% or greater reduction in seizure frequency of BGG492 during the maintenance period. [ Time Frame: 28 days ] [ Designated as safety issue: No ]
  • Safety and tolerability of BGG492 compared to placebo. [ Time Frame: 12 weeks ] [ Designated as safety issue: Yes ]
  • Pharmacokinetic profile of BGG492 [ Time Frame: 10 weeks ] [ Designated as safety issue: No ]

Inclusion Criteria:

  • Outpatients ≥ 50 kg (110 lb) of weight.
  • A diagnosis of epilepsy (≥ 2 years prior to screening) with partial seizures with or without secondarily generalized seizures.
  • Uncontrolled partial seizures despite having been treated with at least two different antiepileptic drugs (AEDs) within the last 2 years prior to screening.
  • At least 4 partial seizures during the 4-week baseline period and at least 4 partial seizures during the 4 weeks prior to the baseline period.
  • Cohort 1 patients must be receiving stable treatment with 1 or a maximum of 2 AEDs.Cohort 2 patients must be receiving stable treatment with 1, 2, or 3 AEDs.

Exclusion Criteria:

  • History of psychogenic seizures.
  • Absences, myoclonic seizures e.g. in the context of primary generalized epilepsy.
  • Previous history of Lennox-Gastaut syndrome.
  • Status epilepticus or seizure clusters, according to the judgement of the investigator, occurring within 52 weeks prior to randomization.
  • Pregnant or nursing (lactating) women.

Other protocol-defined inclusion/exclusion criteria may apply
