Clinical Trial Summary

The purpose of this study is to assess the safety and efficacy of CORT113176 (dazucorilant) in patients with Amyotrophic Lateral Sclerosis (ALS).

Description:

Eligible ALS patients will be randomized to one of three treatment arms (1:1:1) across North America and Europe for a 24-week double-blind treatment period.

Patients who complete participation (i.e., completed all visits) in the double-blind treatment period will be eligible for participation in a 132-week open-label extension (OLE) study. A daily dose of 300 mg dazucorilant will be used in the 132-week OLE period.

Patients that complete the double-blind treatment period and who do not enter the OLE will enter the 132-week follow-up period.
