Design outcomes

Primary

MeasureTime frame
Main Objective: To determine if Triumeq improves survival in patients with ALS;Secondary Objective: To determine if Triumeq improves secondary outcomes and selected biomarkers compared with placebo.;Primary end point(s): The primary endpoint is overall survival, defined as time to mortality from any cause ;Timepoint(s) of evaluation of this end point: Up to Month 24

Secondary

MeasureTime frame
Secondary end point(s): 1. To assess the effect of Triumeq versus placebo on a combined assessment of survival and measures of daily functioning (CAFS) 2. To assess the effect of Triumeq versus placebo on measures of daily functioning 3. To assess the effect of Triumeq versus placebo on respiratory function 4. To assess the effect of Triumeq versus placebo on plasma creatinine 5. To assess the effect of Triumeq versus placebo on the time to reach advanced disease stages 6. To evaluate the safety of Triumeq administered orally to participants with ALS 7. To evaluate the tolerability of Triumeq administered orally to participants with ALS 8. To assess the effect of Triumeq versus placebo on change in cognitive functioning 9. To assess the effect of Triumeq versus placebo on change in quality of life 10. To collect research blood and urine samples for post-trial explanatory analyses; markers will be included e.g. urinary P75ECD, plasma neurofilament light and heavy chain, HERV-K, and genotyping ;Timepoint(s) of evaluation of this end point: Up to Month 24
