E.5 End points |

Proportion de patients avec un score SARA amélioré d'au moins un point au bout de 12 mois |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
|
E.5.2 | Secondary end point(s) |
a. Decrease in the SARA score during one year
b. Decrease in the SARA score as compared to the natural evolution. SARA scores will be measured at M0, M6 and M12. Pre-trial scores history within the previous years will be recorded when available.
c. Decrease in the CCFS score during one year of treatment. CCFS scores will be measured at M0, M6 and M12. Pre-trial scores history within the two previous years will be recorded when available.
d. Change in the INAS score during one year of treatment. INAS score will be measured at M0, M6 and M12. A specific focus on the INAS items fasciculations, amyotrophy and paresis:
- Fasciculation: at least one of the 3 body part with presence of fasciculations
- Amyotrophy: Upper limb distal and/or Tongue
- Paresis: Upper limb proximal and/or distal
e Decrease or stabilization of the volume of cerebellar and brainstem during one year of treatment with riluzole in SCA2 patients using volumetric 3T MRI at M0 and M12.
f. The benefit of riluzole use on patient quality of life will be evaluated using a standardized quality of life questionnaire (SF-36) at M0 and M12.
g. Long-term tolerance will be confirmed by clinical examination at study visits and by blood analysis (hepatic measurements, blood cell count) every month during the first 3 months of treatment, then every 3 months, at their home laboratory.
h. Survival will be analyzed depending of the number of death observed during the study.
