Methylphenidate to Address Attention and Executive Deficits Among Children With Sickle Cell Disease
Pilot Trial of Stimulant Treatment to Address Attention and Executive Deficits Among Children With Sickle Cell Disease
Sponsor: St. Jude Children's Research Hospital
Listed as NCT07226219, this observational or N/A phase trial focuses on Attention Deficit/Hyperactivity Disorder (ADHD) and Cognitive Impairment and remains actively recruiting participants. Sponsored by St. Jude Children's Research Hospital, it has been updated 3 times since 2025, reflecting limited change activity. Mental health research at this phase helps define safety and dosing parameters for future study.
Study Description(click to expand)Children with sickle cell disease (SCD) are at higher risk for executive functioning (EF) deficits, including attention, working memory, and inhibitory control. These deficits are associated with poor academic performance, reduced quality of life, and challenges transitioning to adult healthcare. Despite the effectiveness of stimulant medications like methylphenidate (MPH) in improving EF in the general population and other medical groups, their use in children with SCD is rare. This is a single-arm, open-label pilot trial conducted at St. Jude Children's Research Hospital. Thirty children with SCD and EF deficits will receive a 4-week course of extended-release MPH (10 mg or 20 mg daily, based on weight). Extended-release methylphenidate will be administered once daily for 4 weeks. The initial dose will be given in clinic, followed by home administration. Adherence will be monitored via weekly video pill counts. The study will enroll 30 patients aged 8.0 to 17.9 years with SCD and EF impairment, along with 30 caregivers. An additional 12 caregivers who decline participation will be interviewed to assess decision-making and treatment barriers. Neurobehavioral assessments and side effect evaluations will be conducted at baseline, immediately post-dose, and weekly during the home medication phase. Parents will complete rating scales and interviews...

Eligibility Summary
The purpose of this study is to determine if patients with sickle cell disease (SCD) can consistently take a drug called Methylphenidate (MPH) daily, once a day for 4 weeks to help with any thinking, attention or schoolwork problems and if they have any side effects. The study will assess any thinking or attention problems participants may have both before taking this drug and after. Additionally, the study will assess the decision-making process of the caregiver that may influence using this drug or not. Primary Objective: • Assess the feasibility, acceptability, and adherence to MPH treatment in children with SCD and EF deficits. Secondary Objective: • Evaluate neurobehavioral and safety outcomes following MPH treatment. Exploratory Objective: • Evaluate decision-making and determinants influencing methylphenidate utilization among parents.
