Evaluating blood collection devices for monitoring phenylketonuria in children

Evaluation of Capillary Blood Collection Devices (Mitra® and HemaPEN®) in the Context of Metabolic Diseases and, in Particular, Pediatric Monitoring of Phenylketonuria

Observational University Hospital, Grenoble · NCT05894122

This study is testing two easy-to-use blood collection devices to see if they can help children with phenylketonuria check their phenylalanine levels at home.

What this trial studies

This study aims to assess the effectiveness of capillary blood collection devices, specifically Mitra® and HemaPEN®, for monitoring phenylalanine levels in children with phenylketonuria and hyperphenylalaninemia. The devices are designed for ease of use, allowing for repeated blood sampling at home and the ability to send samples by post. This approach is particularly beneficial for children who require regular monitoring of their metabolic condition. The study will involve children aged 3 months to 18 years who have previously undergone blood testing at the participating hospital.

Who should consider this trial

Good fit: Ideal candidates for this study are children aged 3 months to 18 years diagnosed with phenylketonuria or hyperphenylalaninemia.

Not a fit: Patients whose parents or legal guardians oppose participation in the MitrAlanine study may not receive any benefit.

Why it matters

Potential benefit: If successful, this study could provide a more convenient and efficient method for monitoring phenylalanine levels in children with metabolic diseases.

How similar studies have performed: While this approach is innovative for metabolic diseases, similar blood collection devices have shown success in pharmacological applications.
