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

Condition or disease Intervention/treatment Phase
Amyotrophic Lateral Sclerosis Drug: Dazucorilant 300 mg Drug: Dazucorilant 150 mg Other: Placebo Phase 2

Detailed Description:

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

Patients who complete participation (i.e., complete all visits) in the double-blind treatment period will be eligible for participation in a 24-week open-label extension (OLE) study. A daily dose of 300 mg dazucorilant will be used in the 24-week OLE period.

Patients that complete the double-blind treatment period and who do not enter the OLE will enter the 24-week follow-up period.
