Brief Summary:
NatHis-SMA is a prospective, longitudinal and interventional study of the natural history of patients with type 2 and 3 Spinal Muscular Atrophy (SMA). The purpose of this study is to characterize the disease course over 2 years and identify prognostic variables of the disease and biomarkers of SMA progression, as well as determine the best outcome measures for further therapeutics approaches.

Condition or disease Intervention/treatment Phase

Primary Outcome Measures :
  1. Change from baseline of muscle strength [ Time Frame: Baseline and then every 6 months until end of the study, up to 24 months ]
    Study-specific assessments: Grip and pinch strength

  2. Change from baseline of motor function [ Time Frame: Baseline and then every 6 months until end of the study, up to 24 months ]
    Study-specific assessments: Moviplate and MFM scores, upper extremity functional reaching volume, timed tests (time to rise from floor, time to walk 10 meters, time to climb and descend stairs, distance walked on the Six-Minute Walk Test)


Secondary Outcome Measures :
  1. Change from baseline of respiratory function [ Time Frame: Baseline and then every 6 months until end of the study, up to 24 months ]
    Study-specific assessments: Pulmonary function tests

  2. Change from baseline of physical activity of upper limbs movements [ Time Frame: Baseline and then every 6 months until end of the study, up to 24 months ]
    Quantity and duration of movements, time of inactivity during the day

  3. Change from baseline of skeletal muscle nuclear magnetic resonance (NMR) imaging (MRI) [ Time Frame: Baseline and then every 12 months until the end of the study, up to 24 months ]
    Muscle volume changes, intramuscular fatty infiltration progression, indices of disease activity (only for Paris and Strasbourg sites and for patients older than 4 years)

  4. Change from baseline of electrophysiology measurements [ Time Frame: Baseline and then every 6 months until end of the study, up to 24 months ]
    Compound Motor Action Potential (CMAP) Amplitude and Decrement search

  5. Change from baseline of Biomarkers of SMA progression [ Time Frame: Baseline and then every 6 months until end of the study, up to 24 months ]
    SMN mRNA and protein analysis, SMA exploratory biomarkers (e.g. mRNA, DNA profiling, RNA profiling, proteomic profiling)
