A Study to Assess the Efficacy and Safety of Adjunctive Zonisamide in Paediatric Partial Onset Seizures (CATZ Extension Study)

2014-07-23 21:08:53 | BioPortfolio

Summary

The purpose of this study is to assess the long-term safety and efficacy of zonisamide used as an adjunctive treatment in pediatric subjects treated with 1 or 2 other anti-epileptic drugs (AEDs).

Description

Those subjects who completed the double-blind study (E2090-E044-312) will be invited to participate in this extension study. The study consists of two main parts: Transition Period (double-blind) and Open Label Period. The study will start with the Transition Period during which subjects already on zonisamide will continue on the same dose of zonisamide and those who were taking placebo will be up-titrated to an appropriate dose of zonisamide. After all subjects have completed the Transition Period, the study will become open-label with every subject on the study receiving zonisamide. The study medication will be taken once daily in the evening. For those subjects previously in the placebo group, dosing with zonisamide will start with a dose of approximately 1 mg/kg. In order that the blind is maintained from the previous study, these subjects will initially continue taking the same number of placebo capsules as they were taking in the Maintenance Period of the E2090-E044-312 study until the up- titration is completed. Those subjects previously in the zonisamide arm will continue on the same dose which they received during the Maintenance Period of the E2090-E044-312 study. In order that the blind is maintained, they will also take placebo capsules in order to mirror the up- titration dose regimen of the subjects previously randomized to receive placebo in the E2090-E044-312 study. All subjects will stop taking placebo capsules after the Transition Period is complete. The duration of the Transition Period depends on the dose the subject appeared to have received when completing the core study E2090-E044-312. For those who completed on 8 mg/kg, the Transition Period will last 7 weeks. For those on 6 mg/kg, the Transition Period will last 5 weeks. However, during the double-blind Transition Period, some subjects may experience adverse events (AEs). If this should occur, the subject may be down titrated to one level above the minimal dose. The overall duration of the study will be up to 59 weeks.

Medical and Biotech [MESH] Definitions

A disorder characterized by recurrent focal onset seizures which have sensory (i.e., olfactory, visual, tactile, gustatory, or auditory) manifestations. Partial seizures that feature alterations of consciousness are referred to as complex partial seizures (EPILEPSY, COMPLEX PARTIAL).

Conditions characterized by recurrent paroxysmal neuronal discharges which arise from a focal region of the brain. Partial seizures are divided into simple and complex, depending on whether consciousness is unaltered (simple partial seizure) or disturbed (complex partial seizure). Both types may feature a wide variety of motor, sensory, and autonomic symptoms. Partial seizures may be classified by associated clinical features or anatomic location of the seizure focus. A secondary generalized seizure refers to a partial seizure that spreads to involve the brain diffusely. (From Adams et al., Principles of Neurology, 6th ed, pp317)

An anticonvulsant used for several types of seizures, including myotonic or atonic seizures, photosensitive epilepsy, and absence seizures, although tolerance may develop. It is seldom effective in generalized tonic-clonic or partial seizures. The mechanism of action appears to involve the enhancement of GAMMA-AMINOBUTYRIC ACID receptor responses.

A disorder characterized by recurrent partial seizures marked by impairment of cognition. During the seizure the individual may experience a wide variety of psychic phenomenon including formed hallucinations, illusions, deja vu, intense emotional feelings, confusion, and spatial disorientation. Focal motor activity, sensory alterations and AUTOMATISM may also occur. Complex partial seizures often originate from foci in one or both temporal lobes. The etiology may be idiopathic (cryptogenic partial complex epilepsy) or occur as a secondary manifestation of a focal cortical lesion (symptomatic partial complex epilepsy). (From Adams et al., Principles of Neurology, 6th ed, pp317-8)

A disorder characterized by recurrent localized paroxysmal discharges of cerebral neurons that give rise to seizures that have motor manifestations. The majority of partial motor seizures originate in the FRONTAL LOBE (see also EPILEPSY, FRONTAL LOBE). Motor seizures may manifest as tonic or clonic movements involving the face, one limb or one side of the body. A variety of more complex patterns of movement, including abnormal posturing of extremities, may also occur.
