Brief Summary:
Baseline Study on Duchenne Muscular Dystrophy (DMD) in view to collect data on the natural disease course in a cohort in young male subjects aged from 5 to 9 Years over a period of 6 to 36 months using disease appropriate evaluations.

Condition or disease
Duchenne Muscular Dystrophy

Detailed Description:

Study duration from FPFV: Q1 2019 to LPLV: Q3 2023

Primary Ojectives:

  • To assess the natural disease course using standardized and disease appropriate evaluations over a period of 6 to 36 months in a cohort of young male subjects aged from 5 to 9 years at inclusion and diagnosed for Duchenne Muscular Dystrophy (DMD).
  • To record a baseline period prior to the setup of an AAV gene therapy dose escalation phase I/II First in Man clinical study.

Secondary Objectives:

  • To identify clinical, imaging and/or laboratory parameters that could be predictive indicators of the disease course in DMD, within the selected range of age.
  • To identify the best outcome measure(s) for further clinical trial assessments.
