Efficacy, Safety and Tolerability of TRI476 (Oxcarbazepine) in Children With Inadequately Controlled Partial Onset Seizures

July 9, 2014 updated by: Novartis Pharmaceuticals

A Multicentre, Randomized, Double-blind, Placebo Controlled, Parallel-group Study in Children With Inadequately Controlled Partial Onset Seizures to Investigate Efficacy, Safety and Tolerability of TRI476 (Oxcarbazepine) as Adjunctive Therapy

This study is designed to provide short term efficacy and safety data of TRI476 in children with inadequately-controlled partial seizures. Patients will be randomized into either drug treatment or placebo group at 1:1 ratio, and receive their respective treatment for 8 weeks. The purpose of study is to confirm that TRI476 as adjunctive therapy is effective and safe.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

4 years to 14 years (Child)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • Male and female outpatients, aged 4 to 14 years (inclusive), with a minimum body weight of 15 kg.
  • A diagnosis of partial onset seizures, which include the seizure subtypes of simple, complex, and secondarily generalized seizures (based on the International League Against Epilepsy (ILAE) Classification, as modified in 1981).

Exclusion Criteria:

  • A document history of generalized status epileptics in the past 6 months.
  • Seizures having a metabolic, neoplastic, or active infectious origin.

Other protocol-defined inclusion/exclusion criteria may apply

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Percent Change in Partial Onset Seizure Frequency Per 28 Days From Baseline to the Double-blind Phase, by Treatment Group
Time Frame: screening and 28 days
Percent change in partial onset seizure frequency per 28 days during the double-blind phase from the screening phase, was calculated according to the following formula: "Percent change in partial onset seizure frequency per 28 days from the screening phase" = (partial onset seizure frequency per 28 days during the double-blind phase - partial onset seizure frequency per 28 days during the screening phase) / partial onset seizure frequency per 28 days during the double-blind phase x 100 "Partial onset seizure frequency per 28 days" = Number of partial onset seizures during each phase (screening phase or double-blind phase) / number of days during the screening or double-blind phase × 28.
screening and 28 days

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Partial Seizure Frequency Per 28 Days, by Study Period (Every 28 Days) and Treatment Group
Time Frame: baseline, 28 days and 56 days
Partial onset seizure frequency per 28 days during a period between baseline and Week 4 was measured. Partial onset seizure frequency per 28 days (count/28 days)" = Number of partial onset seizures during each phase (screening phase or double-blind phase) / Number of days during the phase x 28.
baseline, 28 days and 56 days
Percent of Participants With Response During Double-blind Phase, by Treatment Group
Time Frame: screening to 28 days
Responder rate was defined as the percent of participants with an at least 50% reduction in partial onset seizure frequency per 28 days from the screening phase.
screening to 28 days
Percent Change in Partial Onset Seizure Frequency During the Double-blind Phase by Seizure Type
Time Frame: 28 days
Percent change in seizure frequency from baseline = 100 (T-B)/B, B=Seizure frequency per 28 days during baseline phase, T=Seizure frequency per 28 days during the double-blind phase. Seizure frequency per 28 days is calculated as: (seizure frequency during the double-blind phase / the number of days the seizure information were provided) x 28. Only patients with both baseline and corresponding post-baseline values are included.
28 days
Number of Participants With Clinical Global Impression of Change (CGIC) at Final Assessment, by Treatment Group
Time Frame: 56 days
Clinical Global Impression of Change (CGI) is rated on a 7-point scale, with the severity of illness scale using a range of responses from 1 (normal) through to 7 (amongst the most severely ill patients). CGI-C scores range from 1 (very much improved) through to 7 (very much worse).

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
