简要总结
Autism spectrum disorder (ASD) is a neurodevelopmental condition that affects communication, behavior, and social interaction in children. Current treatments are limited and mainly focus on managing symptoms. This study aims to evaluate whether folinic acid is safe and effective in improving symptoms of autism spectrum disorder in children. Participants will be randomly assigned to receive either folinic acid or a placebo during the double-blind treatment phase. After this phase, all participants will have the option to receive folinic acid in an open-label extension. The results of this study may help determine whether folinic acid could be a potential treatment option for children with autism spectrum disorder.
详细描述
This study is a double-blind, randomised, placebo-controlled clinical trial designed to evaluate the safety and effectiveness of folinic acid in children with autism spectrum disorder (ASD). Eligible participants will be randomly assigned to receive either 2 mg/kg/day of folinic acid or a matching placebo during a 12-week double-blind randomised controlled trial (RCT) treatment phase. Neither the participants, caregivers, nor study staff will know which treatment is assigned during this period. The primary aim is to assess whether folinic acid improves symptoms of autism spectrum disorder. Following completion of the double-blind phase, participants will enter a 12-week open-label extension, during which all participants will receive 2 mg/kg/day of folinic acid. This extension phase will allow for further evaluation of longer-term safety and potential benefits. The findings from this study may contribute to a better understanding of the role of folinic acid as a potential treatment option for children with autism spectrum disorder.
