Long-Duration Stimulant Treatment Study of ADHD in Young Children

New York State Psychiatric Institute11 enrolled

Overview

This study will evaluate if Ritalin LA™ is safe and effective for ADHD treatment in 4-to-5-year olds.

This is a single site, open-label, four-week feasibility study of long-duration beaded methylphenidate (B-MPH), also known as Ritalin LA™. B-MPH is a FDA-approved medication for children 6 years and older with attention-deficit/hyperactivity disorder (ADHD), but there are no studies of its use in preschoolers. This study will evaluate the safety and effectiveness of B-MPH for ADHD treatment in 4-to-5-year old children. Total study duration is approximately 5 weeks. It includes a screening evaluation and 4 weeks of B-MPH treatment with doses ranging from 10 to 30 mg (based on the individual tolerability and efficacy). The study doctor will conduct parent-training sessions during the treatment visits.

Outcomes

Primary Outcomes

Swanson, Nolan, and Pelham Questionnaire (SNAP-IV)

The SNAP-IV Rating Scale is a revision of the Swanson, Nolan and Pelham (SNAP) Questionnaire (Swanson et al, 1983). The SNAP-IV is based on a 0 to 3 rating scale: Not at All = 0, Just A Little = 1, Quite A Bit = 2, and Very Much = 3. Subscale scores on the SNAP-IV are calculated by summing the scores on the items in the subset and dividing by the number of items in the subset. The score for any subset is expressed as the Average Rating-Per-Item, as shown for ratings on the ADHD-Inattentive (ADHD-I) subset. Sub scale ranges from 0-3. Higher scores mean better outcome. Change score from baseline is reported.

Time frame: week 5

Clinical Global Impressions-Severity (CGI-S)

CGI-S is designed to assess severity of illness on a seven-point scale: 1 = normal (not at ll ill) to 7 = among the most extremely ill patients. Range: 0-7, higher score means worse outcome. Change from baseline is reported.

Time frame: week 5

Children's Global Assessment Scale (C-GAS)

Children's Global Assessment Scale (C-GAS) is designed to assess overall functioning across settings. The scale is rated from 1 to 100, with lower scores reflecting poorer adjustment. Change from baseline is reported.

Time frame: week 5
