What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Percentage Change (Reduction) of Partial (Type I) Seizure Frequency Per Week From Baseline Over Time During Treatment Period.

    Positive changes from Baseline indicate an improvement (i.e., a reduction) in seizure frequency per week.

    Measured: Up-titration/Conversion Period (2-8 weeks); Maintenance Period (2-8 weeks to 40-46 weeks)

Secondary outcomes (20)
  1. Percentage Change (Reduction) of Total (Type I, II, III) Seizure Frequency Per Week From Baseline Over Time During Treatment Period.

    Positive changes from Baseline indicate an improvement (i.e., a reduction) in seizure frequency per week.

    Measured: Up-titration/Conversion Period (2-8 weeks); Maintenance Period (2-8 weeks to 40-46 weeks)

  2. Partial (Type I) Seizure Frequency Per Week Over Time During Treatment Period.

    Measured: Up-titration/Conversion Period (2-8 weeks); Maintenance Period (2-8 weeks to 40-46 weeks)

  3. Total (Type I, II, III) Seizure Frequency Per Week Over Time During Treatment Period.

    Measured: Up-titration/Conversion Period (2-8 weeks); Maintenance Period (2-8 weeks to 40-46 weeks)

  4. Change (Reduction) From Baseline in Partial (Type I) Seizure Frequency Per Week Over Time During Treatment Period

    Positive changes from Baseline indicate an improvement (i.e., a reduction) in seizure frequency per week.

    Measured: Up-titration/Conversion Period (2-8 weeks); Maintenance Period (2-8 weeks to 40-46 weeks)

  5. Change (Reduction) From Baseline in Total (Type I, II, III) Seizure Frequency Per Week Over Time During Treatment Period

    Positive changes from Baseline indicate an improvement (i.e., a reduction) in seizure frequency per week.

    Measured: Up-titration/Conversion Period (2-8 weeks); Maintenance Period (2-8 weeks to 40-46 weeks)

  6. Partial Seizure (Type I) Responder Rate (Percent) During the Up-titration/Conversion Phase and by Visit During the Maintenance Phase

    The responder rate is defined as the number of responders. A responder is a patient with a 50% or greater change (reduction) in partial seizure frequency per week.

    Note: Rates were reported as percentages.

    Measured: Up-titration (4 weeks); Maintenance Visits 3-4 (weeks 4-14, 6-15, or 8-16); Visits 4-5 (weeks 14-24, 15-24, or 16-24); Visits 5-6 (weeks 24-36); Visits 6-7 (weeks 36-48)

  7. Partial Seizure (Type I) Maximum Seizure Free Interval (Percentage of Days Belonging to a Seizure Free Interval of 28 Days or More)

    For subjects with up to 24 weeks in the evaluation phase the denominator for each subject is their number of days in the evaluation phase.

    Measured: Subjects with up to 24 weeks of exposure

  8. Partial Seizure (Type I) Maximum Seizure Free Interval (Percentage of Days Belonging to a Seizure Free Interval of 28 Days or More)

    For subjects with greater than 24 weeks in the evaluation phase the denominator for each subject is their number of days in the evaluation phase.

    Measured: Subjects with greater than 24 weeks of exposure

  9. Total Seizure (Type I, II, III) Maximum Seizure Free Interval (Percentage of Days Belonging to a Seizure Free Interval of 28 Days or More)

    For subjects with up to 24 weeks in the evaluation phase the denominator for each subject is their number of days in the evaluation phase.

    Measured: Subjects with up to 24 weeks of exposure

  10. Total Seizure (Type I, II, III) Maximum Seizure Free Interval (Percentage of Days Belonging to a Seizure Free Interval of 28 Days or More)

    For subjects with greater than 24 weeks in the evaluation phase the denominator for each subject is their number of days in the evaluation phase.

    Measured: Subjects with greater than 24 weeks of exposure

  11. Total Seizure (Type I, II, III) Continuously Seizure Free During the Maintenance Period

    The measure description is the product limit adjusted percent of subjects seizure free starting from the beginning of the Maintenance Period.

    The up-titration period is the up to 6 week period of increasing dose prior to the Maintenance Period. The Maintenance Period is the period of stable dosing, subsquent to the up-titration period, which could last from 42 to 48 weeks.

    Measured: greater than or equal to 24 weeks, greater than or equal to 40 weeks

  12. Percent of Subjects With Each Seizure Type During the Evaluation Period

    Type I Seizure is a partial onset Seizure (see International League Against Epilepsy definitions).

    Type II Seizure is a Generalized Seizure (see International League Against Epilepsy definitions).

    Type III Seizure is a Unknown Seizure Type (see International League Against Epilepsy definitions).

    A subject could experience more than one seizure type.

    Measured: Evaluation period (48 weeks)

  13. Investigator Global Evaluation Scale

    There are 7 categories, 3 for improvement (Marked improvement, Moderate improvement, Slight improvement), 3 for worsening (Slight worsening, Moderate worsening, Marked worsening), and 1 for no change (No change).

    Measured: End of Evaluation period (week 48 or at point of early discontinuation)

  14. Parent/Guardian Global Evaluation Scale

    There are 7 categories, 3 for improvement (Marked improvement, Moderate improvement, Slight improvement), 3 for worsening (Slight worsening, Moderate worsening, Marked worsening), and 1 for no change (No change).

    Measured: End of Evaluation period (week 48 or at point of early discontinuation)

  15. Subject (>=8 Years Old) Global Evaluation Scale

    There are 7 categories, 3 for improvement (Marked improvement, Moderate improvement, Slight improvement), 3 for worsening (Slight worsening, Moderate worsening, Marked worsening), and 1 for no change (No change).

    Measured: End of Evaluation period (week 48 or at point of early discontinuation)

  16. Leiter-R Associated Memory (AM) Memory Screen Composite Score Change From Baseline to Visit 5 (Week 24) and Visit 7 (Week 48) (4 to 16 Year Olds)

    The Leiter-R AM battery has 10 subtests. The raw scores of the subtests are converted into scaled scores. Six composite scores are constructed from the 10 subtest scaled scores. The Memory Screen is one of them. It is composed of 2 subtests the Associated Pairs and Forward Memory. The sum of the Associated Pairs and Forward Memory subtest scaled scores are converted into a Memory composite score normally distributed with a mean and standard deviation of 100 (±15). Higher scores and positive changes from baseline are better. The range of the Memory Screen composite score is 44 to 155.

    Measured: Baseline to Visit 5 (Week 24) and Visit 7 (Week 48)

  17. Bayley Scale of Infant Development (BSID) II Mental Development Index Scores Classification Shift From Baseline at Visit 5 (Week 24) (1 Month to < 4 Year Olds)

    This score is obtained from a total raw score which is the sum of a battery of individual questions. It is adjusted for a child's age, has an expected mean of 100 and standard deviation of 15, and can be categorized as: (1) Accelerated Performance (>= 115), (2) Within Normal Limits (85-114), (3) Mildly Delayed Performance (70-84), and (4) Significantly Delayed Performance (<=69). Changes from baseline are then further categorized where 'Improved' is any positive category change, 'Stable' is no category change, and 'Worsened' is any negative category change, from baseline.

    Measured: Visit 5 (Week 24)

  18. Bayley Scale of Infant Development (BSID) II Mental Development Index Scores Classification Shift From Baseline at Visit 7 (Week 48) (1 Month to < 4 Year Olds)

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 12 Feb 2013. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 84 sites in United States, Brazil, Germany, India, Italy and 11 more countries. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 13 Jan 2010). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Percentage Change (Reduction) of Partial (Type I) Seizure Frequency Per Week From Baseline Over Time During Treatment Period. (time frame: Up-titration/Conversion Period (2-8 weeks); Maintenance Period (2-8 weeks to 40-46 weeks)). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00152516, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?
