Full Study Summary:

CY 5032 is an open-label extension (OLE) study of the selective fast skeletal muscle troponin activator, reldesemtiv, in patients with ALS who finished dosing (through Week 48) in CY 5031 (COURAGE-ALS). Approximately 400 patients from the sites that participated in CY 5031 are expected to be enrolled in the open-label extension, CY 5032.

Following enrollment, patients will continue dosing with reldesemtiv, 300 mg twice a day for a 600 mg total daily dose (TDD) for a period of 48 weeks.

At the end of 48 weeks, patients may transition to a reldesemtiv Managed Access Program (MAP) the treating physician agrees to participate in the program.

- Completed dosing in CY 5031

Exclusion Criteria:

- Has taken investigational study drug (other than reldesemtiv) prior to dosing, within 30 days or five half-lives of the prior agent, whichever is greater

- Presence on Day 1 of any medically significant cardiac, pulmonary, gastrointestinal, musculoskeletal, or psychiatric illness that might interfere with the patient's ability to comply with study procedures or that might confound the interpretation of clinical safety or efficacy data.

- Use of a strong cytochrome P450 (CYP) 3A4 inhibitor within 7 days prior to first dose of reldesemtiv in CY 5032 or a strong CYP3A4 inducer within 14 days prior to first dose of reldesemtiv in CY 5032

- Use of a medication that is an OCT1/OCT2 substrate within 7 days prior to first dose of reldesemtiv in CY 5032

- Currently participating in another trial, managed access program, open label extension, early access program, or through the right to try act is receiving an investigational drug or received an investigational drug or device within 30 days (or 5 half-lives for drugs, whichever is longer) prior to Day 1. Patients also cannot be taking outside of a clinical trial certain investigational drugs (which includes drugs, supplements, and nutraceuticals) that are currently being studied or have been studied for the treatment of ALS.
