| Measure | Time frame |
|---|---|
| Main Objective: Efficacy of pioglitazone (45 mg/day) as add-on therapy to standard therapy with riluzole in patients with amyotrophic lateral sclerosis compared to placebo in terms of survival (mortality defined exclusively as death).;Secondary Objective: Secondary efficacy variables will include incidence of tracheotomy or non-invasive ventilation (NIV), ALS Functioning Rating Scale (ALSFRS-R; the revised version including the respiratory parameters), and measurement of quality of life using the Euroqol EQ-5D. Clinical tolerability and safety will be assessed by findings of physical examination, adverse events incidence, and clinical laboratory values.;Primary end point(s): Efficacy of pioglitazone (45 mg/day) as add-on therapy to standard therapy with riluzole in patients with amyotrophic lateral sclerosis compared to placebo in terms of survival (mortality defined exclusively as death). The primary endpoint will be subjected to a confirmatory analysis. All secondary and safety parameters will be evaluated and reported descriptively. | — |
