Safety and Efficacy of Olesoxime (TRO19622) in 3-25 Years SMA Patients.

Spinal Muscular Atrophy Type II Clinical Trial

Official title: Phase II, Multicenter, Randomized, Adaptive, Double-blind, Placebo Controlled Study to Assess Safety and Efficacy of Olesoxime (TRO19622) in 3-25 Year Old Spinal Muscular Atrophy (SMA) Patients.

Status Completed

Clinical Trial Summary

Assess the efficacy and the safety of olesoxime in SMA type 2 or type 3 non ambulant patients aged 3-25 years

Clinical Trial Description

This study is a multicenter, double-blind, randomized, adaptive, parallel groups, placebo controlled 3-stage study in patients with SMA type 2 or non ambulant type 3.

Stage 1 DMC 3-month safety assessment: An independent Data Monitoring Committee (DMC)will assess the safety of olesoxime every 3 months.

Stage 2 Efficacy/futility analyses at one year: A first interim efficacy analysis will be performed after all patients have been treated for one year (52 weeks) in order to assess the need to continue the study to reach the planned objective. In the event of positive and significant results in favor of olesoxime, the study will be considered as successful and all patients will be switched to olesoxime to allow the assessment of the sustainability of the treatment effect and safety. If the results are significantly in favor of placebo, the study will be discontinued for failure (futility).

Stage 3 Efficacy and safety analysis at two years: The expected study duration is of 2 years (104 weeks) to show efficacy. If the study is not discontinued for futility or medication regimen is changed due to success, the study will therefore continue until planned completion i.e. 104 weeks. ;
