Brief Summary

Children with sickle cell disease (SCD) exhibit significantly reduced cognitive functioning (often difficulties with attention) compared to peers and siblings without SCD. EndeavorRx (Akili Interactive Labs: Boston, MA) is an FDA-approved home-based, electronic attentional-control training program designed to treat attention problems in youth. Users access EndeavorRx on a tablet device for 25-30 minutes each day, 5 days per week, for 4 weeks. The program involves training in a game-like environment that repeatedly challenges attentional-control abilities and adapts to user performance, becoming more difficult over time as performance improves. This pilot study is examining the feasibility, acceptability, and preliminary efficacy of EndeavorRx in a sample of 20 children with SCD ages 8-16 who are being treated with chronic blood transfusion therapy.

Detailed Description

Children with sickle cell disease (SCD) exhibit significantly reduced cognitive functioning compared to peers and siblings without SCD. Cognitive deficits are greatest among those with severe SCD genotypes, persistent anemia, and strokes and these deficits worsen over time. These deficits often manifest as difficulties with executive functioning and attention due to the predominance of cerebral infarcts (\>90%) that occur in the frontal cortex. Reduced capacity to engage such cognitive skills has significant real-world implications, leading to disruption to academic achievement and attainment, vocational outcomes, and quality of life. EndeavorRx (Akili Interactive Labs: Boston, MA) is an FDA-approved home-based, electronic attentional-control training program designed to treat attention problems in youth. Users access EndeavorRx on a tablet device for 25-30 minutes each day, 5 days per week, for 4 weeks. The program involves training in a game-like environment that repeatedly challenges attentional-control abilities and adapts to user performance, becoming more difficult over time as performance improves. Data support effects of EndeavorRx on performance-based and parent-reported measures of attention in youth with Attention-Deficit/Hyperactivity Disorder (ADHD). Given the similarities in attentional functioning among youth with ADHD and those with SCD, EndeavorRx holds promise as an intervention for patients experiencing SCD-related cognitive deficits. This pilot study is examining the feasibility, acceptability, and preliminary efficacy of EndeavorRx in a sample of 20 children with SCD ages 8-16 who are being treated with chronic blood transfusion therapy due to an identified high risk of stroke or as a preventive measure to protect against additional stroke events.

Study & Design

Study Type
INTERVENTIONAL
Study Design
SINGLE_GROUP
Arm && Interventions
GroupInterventionDescription
EndeavorRxEndeavorRxChildren will be asked to begin attentional control training at home within two weeks of baseline testing and to complete 6 training missions per day (25-30 minutes), 5 days per week, for 4 weeks (total = 120 training missions).
Primary Outcome Measures
NameTimeMethod
EndeavorRx feasibility assessed by patient/family interestApproximately 10 months

Feasibility will be determined by examining the proportion of eligible patients/families approached about the study who enroll.

EndeavorRx feasibility assessed by reports of technical ease-of-use and satisfactionApproximately 4 weeks from start of intervention

Feasibility will be determined by examining parent and child reports of technical ease-of-use and satisfaction.

EndeavorRx feasibility assessed by program completion ratesApproximately 4 weeks per participant

Feasibility will be evaluated by examining the proportion of the sample that completes at least 60 EndeavorRx missions (50%).

Secondary Outcome Measures
NameTimeMethod
Inattention assessed by change in Omission Errors on the Conners' Continuous Performance Test, 3rd Edition (CPT-3)Approximately 4 weeks from start of intervention

EndeavorRx efficacy will be evaluated by examining change in Omission Errors on the CPT-3 computerized assessment after completing EndeavorRx.

Inattention assessed by change in the Inattention subscale of the ADHD Rating Scale, Fifth Edition (ADHD-RS-V)Approximately 4 weeks from start of intervention

EndeavorRx efficacy will be evaluated by examining change in the Inattention subscale of the parent-reported ADHD-RS-V after completing EndeavorRx.
