Understanding how trihexyphenidyl works in children with dystonic cerebral palsy

Official title: Pharmacogenomic Contribution to the Biotransformation of Trihexyphenidyl and Development of a Precision Dosing Model for Children With Dystonia and Cerebral Palsy

Run by Children's Mercy Hospital Kansas City · NCT06554288 · Data updated 2026-11-12

This study is testing how well the medication trihexyphenidyl works for children with dystonic cerebral palsy and if their genes affect how the drug works.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are children aged 5-17 diagnosed with cerebral palsy and dystonia that interferes with their daily activities.

Probably not a fit

Patients who are currently taking trihexyphenidyl or will turn 18 during the study period may not benefit from this study.

What this trial studies

This study investigates the effects of trihexyphenidyl in children aged 5-17 with dystonic cerebral palsy. It aims to evaluate how the medication is metabolized in the body and whether genetic factors influence its effectiveness. The study will last for 16 weeks and will help inform the design of future clinical trials based on the findings regarding pharmacokinetics and genetic variations. It is a single-arm, nonrandomized pilot study focused on understanding the drug's biotransformation and response in pediatric patients.

Why it matters

Potential benefit: If successful, this study could lead to more effective treatment strategies for children with dystonic cerebral palsy.

How similar studies have gone: While pharmacogenomic approaches in pediatric populations are being explored, this specific study's focus on trihexyphenidyl and its genetic interactions is relatively novel.
