 (submitted: December 5, 2018)
  • Number of Participants Reporting Improvement on the Clinical Global Impression [ Time Frame: Baseline to end of study (week 15) ]
    The CGI-I is a 7-point improvement scale. Ratings of 1 or 2 (responders) indicate a substantial reduction in symptoms. A rating of 3 (minimally improved) on the CGI is defined as a slight symptomatic improvement that is not deemed clinically significant; patients with such an improvement were not considered responders. Two versions of this test were used, one focused on irritability (primary outcome measure) and a general version CGI-I-autism focused on all symptoms including core symptom domains. The CGI-I irritability took into consideration the scores from the ABC-Irritability subscale, the OAS-M aggression and irritability subscales and information from open-ended questioning related to the degree of interference, nature, and range of behavioral problems at school and at home
  • Change in Aberrant Behaviors as Measured by the Aberrant Behavior Checklist Scores [ Time Frame: Baseline and End of Study (week 15) ]
    The Aberrant Behavior Checklist is designed to objectively identify five behavior sub scales through observation by the primary caregiver: irritability, lethargy, stereotypy, hyperactivity, and inappropriate speech. The ABC was filled out by parents on a scale from 0-3 for each category. (0 being not a problem, 3 being severe problem). Scores from all sub scales were added (scoring 0-45 for Irritability subscale, 0-48 for Lethargy subscale, 0-21 for stereotypy scale, 0-48 for hyperactivity sub-scale, and 0-12 for inappropriate speech sub-scale) to obtain a total score.

Descriptive Information
Brief Title  ICMJE Divalproex Sodium vs. Placebo in Childhood/Adolescent Autism
Official Title  ICMJE Divalproex Sodium vs. Placebo in Childhood/Adolescent Autism
Brief Summary The study is designed to assess the efficacy of treatment with divalproex sodium (DS) vs. placebo in childhood/adolescent autism fulfilling DSM-IV and Autism Diagnostic Interview (ADI) criteria. Currently, there are no FDA-approved treatments for this disorder, although behavioral and educational therapies and a variety of medications may play a role in the management of some autistic symptoms.
Detailed Description This study compares divalproex sodium and placebo in the treatment of autistic disorder. Twenty six child or adolescent outpatients, with age ranges from 5-17, will be randomized into a 12-week double-blind, placebo-controlled parallel treatment study. During the 12 weeks, patients will be monitored by the treating psychiatrist and assessed by an independent evaluator (IE). The IE will perform study assessments while remaining blind to medication regimens (including possible tapering) as well as any side effects. Study assessments will be administered at designated time points

Eligibility Criteria  ICMJE

Meets DSM-IV, ADI, and ADOS criteria for autistic disorder

Age 5-17.

Outpatients

Parent/legal guardian signing informed consent, and assent documented for patient with demonstrated capacity to provide it.

Sexually active females of childbearing potential must use an acceptable method of birth control (oral contraceptive medications [the administration of which must be supervised by a parent or guardian], IUD, depot medication or tubal ligation) and have a negative serum pregnancy test prior to entry into the study.

Subject scores at least "4" (moderately ill) on the Clinical Global Impression-Severity Scale for Autistic Disorder (CGI-AD).

Subject meets the following criteria at pre-study diagnostic assessment and baseline assessment: OAS-M 13 or ABC-Irritability Subscale 18 (raw scores).

Subjects with history of seizures, who have been seizure-free for 6 months on a stable dose of anticonvulsant medication other than divalproex sodium or related formulations (e.g., depakene). Non-medicated subjects with a history of seizures who have been seizure-free for 6 months. Subjects with abnormal EEG but no clinical seizures.

State exclusion criteria for enrollment in study:

Subjects who are pregnant or nursing mothers. Sexually active women of childbearing potential who are not using adequate birth control measures (detailed above in inclusion criteria).

Subjects with overall adaptive behavior scores below the age of two years on the Vineland Adaptive Behavior Rating Scale.

Subjects with active or unstable epilepsy.

Subjects with any of the following past or present mental disorders: schizophrenia, schizoaffective disorder or organic mental disorders.

Subjects who are a serious suicidal risk.
