Clinical Trial Summary

The study design is a single-subject ABA clinical trial that is investigating the feasibility including adherence, safety and tolerability of metformin in children aged 5 to 18 years with cerebral palsy (CP). ABA refers to Phase A1 with no metformin, Phase B with metformin, and Phase A2 with no metformin. Secondarily, the study is exploring whether metformin has possible health benefits for improving motor function and cognition.


Clinical Trial Description

The trial is designed as a 48 week limited institution two-site single case ABA study feasibility trial. ABA refers to Phase A1 with no metformin, Phase B with metformin, and Phase A2 with no metformin. Primary endpoints are feasibility, including recruitment, adherence to study medication and outcome measure completion, safety and tolerability of metformin. Key secondary endpoints are gross motor function and sustainability of intervention. Exploratory endpoints are cognitive and MRI measures as well as qualitative information regarding barriers to participation. All participants will receive the study drug (metformin) during the 16 week intervention period. This study will be done at two different locations in Toronto 1) Holland Bloorview Kids Rehabilitation Hospital and 2) the Hospital for Sick Children (SickKids). Each participant will be asked to go to both hospitals to do different tests and assessments for the study. Ten participants with physician diagnosis of CP age 5 to 18 with evidence of white matter imaging (WMI) or Grey Matter Imaging (GMI), and gross motor function classification system (GMFCS) levels II-V will be recruited for participation. MRI, cognitive testing and focus groups will be conducted at SickKids where paediatric protocols and processes have been developed. ;
