Rivastigmine Study in Adolescents With Down Syndrome
A 20-Week Double-Blind Placebo Controlled Clinical Trial to Evaluate the Safety and Efficacy of Rivastigmine in Children (Ages 10-18) With Down Syndrome

The purpose of this study is to determine if short term use of rivastigmine can improve functional abilities (for example, language, memory, and executive function) in adolescents with Down syndrome.

This 24 week, double-blind, placebo controlled trial will be completed at the Clinical Research Unit of Duke University Medical Center and at the Kennedy Krieger Institute (KKI). Sixteen evaluable subjects will be enrolled at Duke and 24 evaluable subjects will be enrolled at KKI. The study consists of four visits, a screening visit (-4 weeks), a baseline visit (week 0); a safety visit at week 10, and a final/termination visit at week 20.

The specific aims of this study are to: a) investigate efficacy of rivastigmine tartrate treatment; b) build upon our open-label treatment results of overall function and language improvement in adolescents with Down syndrome (DS) in a double-blind, placebo-controlled clinical trial; and c) investigate other specific cognitive domains that may selectively respond to rivastigmine tartrate treatment.

Interventional
Phase 1
Phase 2
Allocation: Randomized
Endpoint Classification: Efficacy Study
Intervention Model: Parallel Assignment
Masking: Double Blind (Subject, Caregiver, Investigator, Outcomes Assessor)
Primary Purpose: Treatment
Down Syndrome
  • Drug: Rivastigmine
    At the baseline visit (week 0), the subject will begin rivastigmine treatment at a dose of 0.75 mg bid. This dose will be continued for two weeks and then increased to 1.5 mg bid for an additional eight weeks. At the week 10 safety visit, the dose will be increased to 4.5 mg/day (3.0 mg and 1.5 mg) for an additional 10 weeks. Subjects receiving placebo will maintain the same schedule. If a subject is unable to tolerate a particular dose, the dose will be lowered to the previously tolerated dose, down to a minimum of 0.75 mg bid. If the subject is unable to tolerate the 0.75 mg bid dose he/she will be dismissed from the study.
    Other Name: Rivastigmine-Excelon
  • Other: Liquid Placebo
    Subjects receiving placebo will maintain matched titration volume increase as treatment arm. The placebo will be matched to liquid rivastigmine in consistency and taste.
  • Experimental: Rivastigmine- Liquid form
    At the baseline visit (week 0), the subject will begin rivastigmine treatment at a dose of 0.75 mg bid. This dose will be continued for two weeks and then increased to 1.5 mg bid for an additional eight weeks. At the week 10 safety visit, the dose will be increased to 4.5 mg/day (3.0 mg and 1.5 mg) for an additional 10 weeks. If a subject is unable to tolerate a particular dose, the dose will be lowered to the previously tolerated dose, down to a minimum of 0.75 mg bid. If the subject is unable to tolerate the 0.75 mg bid dose he/she will be dismissed from the study.
    Intervention: Drug: Rivastigmine
  • Placebo Comparator: Liquid placebo
    Subjects receiving placebo will maintain matched titration volume increase as treatment arm. The placebo will be matched to liquid rivastigmine in consistency and taste.
    Intervention: Other: Liquid Placebo
