Spots Global Cancer Trial Database for Efficacy of Computerized Cognitive Training and Stimulant Medication in Neurofibromatosis Type 1

Study Description

Brief Summary: The main objective of the study is to assess the efficacy of a home-based, computerized cognitive training (CT) program, called CogmedRM, targeted to improve working memory in children with NF1 and working memory difficulties. This is a Phase II randomized parallel group controlled clinical trial comparing two interventions on cognitive outcomes. Participants will be stratified by stimulant medication use and randomized equally between the two interventions within stratum. Participants will be in the study for to 11 weeks.

Detailed Description: Cognitive deficits are the most important cause of long-term dysfunction in patients with Neurofibromatosis type 1 (NF1). Among the most frequently-occurring difficulties are problems with attention, working memory (WM), and executive functioning (EF). Remediation and interventions to improve those deficits have the potential to impact the quality of life and long-term prognosis in this population. Cognitive training (CT) programs have increasingly been used independently or in conjunction with pharmacotherapies in children with accidental or disease-related brain injury. CogmedRM is both the most well-researched and widely-used CT program for remediation of WM deficits. Results from numerous randomized, controlled trials conducted with a variety of pediatric and adult patient populations generally show that CogmedRM training is associated with robust gains in performance-based WM scores over the short term, with some variability in improvement across disease groups. A single arm pilot study of CogmedRM in a sample of children with NF1 conducted at Children's National Medical Center has shown that the approach is likely feasible and acceptable to families. Because many children with NF1 are treated with stimulant medications, and there is biological evidence that both CT and Methylphenidate act on dopaminergic systems, the investigators are also interested in examining whether or not there is a synergistic effect between these widely available and safe interventions. Thus, the aim is to assess the efficacy of a home-based, computerized cognitive training (CT) program in a sample of 90 children aged 8-16 with NF1 and working memory difficulties. This study will be conducted over the span of four years. If the participant qualifies following baseline testing, he/she will be randomized to the intervention, CogmedRM, or the active control condition, MobyMax (an online reading program). The participant will have 5-9 weeks to complete the program and will have follow-up testing 2 weeks after finishing the program. If CT, either singly or in combination with stimulant medication, can be shown to be efficacious in a sample of NF1 pediatric patients at high risk for neurocognitive deficits, this intervention plan could be rapidly translated to clinical practice.
