Descripción detallada

This is an open labeled non-comparative, multicentric observational post marketing surveillance study to comparing the safety and efficacy of zonisamide as adjunctive therapy or monotherapy in patients with partial, generalized or combined seizures, in a initiating dose of 100mg/day titrated to a maximum of 600mg per day based on the seizure control and tolerability over a 24 weeks treatment period. This study will include a total of 900 patients with partial, generalized or combined seizures across 30 centres in the country. The patients will be enrolled based on the inclusion and exclusion criteria and will be evaluated for safety and efficacy at every 4 weekly interval for 24 weeks. There will be total 7 study visits and the patients will be evaluated for clinically reportable adverse events, safety on Patients Global Assessment of Tolerability to Therapy (PGATT) on a 4-point scale and for efficacy by evaluation of reduction in seizure frequency as the primary objective of the study. For secondary objectives the patients data will be evaluated to determine the responder rates (> or = to 50% reduction in seizure frequency from baseline) and seizure freedom over the 24 weeks study period.

Descripción

Inclusion Criteria:

  1. Male or female subjects, 18 to 75 years of age inclusive
  2. Treated or untreated subjects suffering from any of the following types of seizures:

    1. Partial Seizures: Simple Partial Seizures, Complex Partial Seizures & Secondarily generalized tonic clonic seizures
    2. Generalized Seizures: Tonic-clonic seizures, tonic seizures & Atypical absence seizures
    3. Combined seizures (mixed)
  3. Subjects having had a computed tomography (CT) or magnetic resonance imaging (MRI) done within the last upto 10 years that ruled a progressive cause of epilepsy.
  4. Female subjects without child bearing potential (2 years postmenopausal, bilateral oophorectomy or tubal ligation, complete hysterectomy) are eligible.
  5. Female subjects with childbearing potential must not be pregnant as confirmed by a negative pregnancy test at screening and enrollment must not be lactating and must be using a medically acceptable form of contraception, for the duration of the study and for one month following discontinuation of the study drug.
  6. Patients willing to take the medications as directed, maintain a seizure dairy, report adverse events and willing to come for the follow-ups as per schedule.
  7. Willing to comply with the protocol requirements.
  8. Able and willing to give the written informed consent.

Exclusion Criteria:

  1. Subjects with history of non-epileptic seizures (e.g. metabolic, pseudo-seizures).
