A Study of the Safety and Efficacy of Depakote Sprinkle Capsules in the Treatment of Partial Seizures in Children

August 2, 2006 updated by: Abbott
The purpose of this study is to compare the safety and efficacy of two concentration ranges of valproate using Depakote Sprinkle Capsules as adjunctive therapy in the treatment of partial seizures, with or without secondary generalization, in children 3-10 years.

Study Overview

Status

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

Enrollment

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

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

3 years to 10 years (Child)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

INCLUSION CRITERIA:

Subject has diagnosis of partial seizures with/without secondary generalization, supported by:

  • Observed ictal events consistent with partial seizures: With/ without secondary generalization; Documented by reliable observers
  • 1 of following 2: EEG at some time in past demonstrating focal abnormalities consistent with partial seizures; OR, in absence of demonstrable EEG abnormality: MRI/CT scan evidence of a focal CNS lesion consistent with partial seizures
  • On stable dose of 1 or 2 antiepileptic drug(s) (AED) other than valproate, for at least 1 month
  • Not taking valproate or is currently receiving valproate resulting in a trough concentration of less than 40 mcg/mL
  • History of at least 4 partial seizures/month in 2 months prior to screening
  • Parent/caregiver is able to keep an accurate seizure diary

EXCLUSION CRITERIA:

  • History of any of following: Lennox-Gastaut syndrome; Primary generalized seizures; Infantile spasms; Mixed seizure disorders including atypical absence; Myoclonic or atonic seizures; Pseudoseizures or Epilepsia Partialis Continuans (EPC)
  • Has had status epilepticus in the past 6 months
  • Has significant history of any of following that would confound study results: Cardiac (including clinically important abnormality on ECG); Renal; Psychiatric (including psychosurgery); Oncologic; Endocrine; Metabolic; Pancreatic; Hepatic disease (including clinical/serological history of hepatitis); Urea cycle disorder
  • Has: Expanding CNS neoplasm; Active CNS infection; Demyelinating disease; Degenerative neurological disease; Progressive encephalopathy; or any Progressive CNS disease

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
Change from baseline in the 4-week partial seizure rate

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
Adverse events
Vital signs
Laboratory data
