Full Study Summary:
Enrolled participants will begin dosing of tirasemtiv 125 mg twice daily (250 mg/day) for a period of 4 weeks and will titrate to their tolerated dose, the maximum dose being 250 mg twice daily (500 mg/day). This study will also compare the clinical course of patients who completed treatment with tirasemtiv in CY 4031 with those who completed treatment with placebo in CY 4031 during continued treatment of both groups with tirasemtiv during CY 4033, compare the clinical course of patients who completed treatment with tirasemtiv in CY 4031 during that study with their clinical course during continued treatment with tirasemtiv during CY 4033, and compare the clinical course of patients who completed treatment with placebo in CY 4031 during that study with their clinical course during treatment with tirasemtiv during CY 4033.

Time to the first occurrence of respiratory insufficiency (defined as tracheostomy or the use of non-invasive ventilation (NIV) for ≥22 hours per day for ≥10 consecutive days) or death [ Time Frame: From date of entry into the study until the date of first documented progression or date of death from any cause, which came first, assessed up to 36 months ] [ Designated as safety issue: No ]
Time to death [ Time Frame: From date of entry into the study until the date of first documented progression or date of death from any cause, which came first, assessed up to 36 months ] [ Designated as safety issue: No ]
Decline in percent predicted Slow Vital Capacity (SVC) from baseline [ Time Frame: From date of entry into the study until the date of first documented progression or date of death from any cause, which came first, assessed up to 36 months ] [ Designated as safety issue: No ]

Slope of the change from baseline in percent predicted SVC [ Time Frame: First 24 weeks and first 48 weeks of either CY 4031 or CY 4033 ] [ Designated as safety issue: No ]
Slope of the change from baseline in ALSFRS-R [ Time Frame: First 24 weeks and first 48 weeks of either CY 4031 or CY 4033 ] [ Designated as safety issue: No ]
