Trial Outcomes & Findings for Long Acting Stimulant Treatment of Attention Deficit Hyperactivity Disorder (ADHD) in Young Children (NCT NCT00754208)

NCT ID: NCT00754208

Last Updated: 2023-10-05

Results Overview

Change from baseline to endpoint of investigator-scored, parent version of the Attention Deficit Hyperactivity Disorder Rating Scale-IV (ADHD-IV rating scale). The ADHD-IV contains 18 items, and each item is rated 0, 1, 2 or 3. Minimum score is 0. Maximum score is 54. Change in score represents the difference between the total score at end point compared to the total score at baseline. Higher scores indicate greater symptom severity.

PRIMARY outcome

Timeframe: 8 weeks

Change from baseline to endpoint of investigator-scored, parent version of the Attention Deficit Hyperactivity Disorder Rating Scale-IV (ADHD-IV rating scale). The ADHD-IV contains 18 items, and each item is rated 0, 1, 2 or 3. Minimum score is 0. Maximum score is 54. Change in score represents the difference between the total score at end point compared to the total score at baseline. Higher scores indicate greater symptom severity.

Change in Attention Deficit Hyperactivity Disorder Rating Scale-IV Parent Version Investigator-Scored (ADHD-IV-Parent: Inv) Total Score.
-20.1 units on a scale
Standard Deviation 13.87

SECONDARY outcome

Timeframe: 8 weeks

Change in global rating of severity of ADHD symptoms. CGI severity is rated on a scale of 1 to 6 (normal to severely ill; refer to description in baseline information). The change in the severity rating reflects the change in this score from baseline to endpoint. The greater the reduction in score the more improvement has been observed.

SECONDARY outcome

Timeframe: 8 weeks

This measures the change in the subject's global assessment of functioning as rated by the clinician. This Children's Global Assessment Scale (CGAS) is rated on a 0-100 scale (refer to baseline information). The change in this score is the difference between the score at baseline to end point. The greater the change score, the more improvement has been observed.

SECONDARY outcome

Timeframe: 8 weeks

The Clinical Global Impression-Improvement scale is a measure of the clinician's assessment of the overall degree of improvement in ADHD symptoms from baseline to endpoint. The CGI-I is rated on a 1 to 6 scale, with 1=very much improved, 2=much improved, 3=minimally improved, 4= no change, 5= minimally worse, 6=much worse. Low numerical score on this scale indicates greater improvement.

Methylpehnidate
n=7 participants at risk
open-label treatment with methylphenidate methylphenidate: Starting dose: methylphenidate (immediate-release pill) or Methylin (immediate-release chewable tablet for those unable to swallow pills) 2.5mg Q AM and Q noon. Target dose of 1mg/kg/day. Titration will occur as follows: 5mg Q AM and Q noon, then 7.5mg Q AM and Q noon, then 10mg Q AM and Q noon, as tolerated, not to exceed 30mg per day. Once each child arrives at a stable dose with a good response and good tolerability, they will be converted to the closest Ritalin LA dose, with a target dose of 1mg/kg/day.
