337This is a Phase III, multi-centre, randomized, double-blind, placebo-controlled, parallel-group study to evaluate Safety and Efficacy of Tauroursodeoxycholic (TUDCA) as add-on Treatment in Patients Affected by Amyotrophic Lateral Sclerosis (ALS).
Enrolled patients will be randomized to one of two treatment arms: TUDCA or identical placebo by oral route. The randomization will be performed in a ratio one to one for the two arms.
TUDCA will be administered orally at the dose of 1 g twice daily (2 g daily) for 18 months. Patients will be taking also riluzole at the dose of 50 mg twice daily (100 mg daily).
Patient randomization will take place after a screening (lead-in) period of 12 weeks (3 months) with 3 assessments at 6-week intervals. Clinical assessments during the trial phase will be performed every three months. This will allow measuring the progression rate before and after starting treatment (either active or placebo).
