A Study to Evaluate the Effects of Multiple Doses of CK-2017357 in Patients With Amyotrophic Lateral Sclerosis (ALS) - Full Text View

Purpose

The study will generate data on safety and tolerability after multiple daily doses of CK-2017357 in patients with ALS. Patients will be randomized into one of four different treatment groups, receiving daily oral doses of either placebo, 125 mg, 250 mg, or 375 mg of CK-2017357 for 14 days.

Arms	Assigned Interventions
Placebo Comparator: Matching Placebo	Drug: Placebo Three matching placebo tablets once daily for 14 days (Part A) or three matching placebo tablets once daily for 14 days taken concurrently with 50 mg riluzole (Part B)
Experimental: Active Drug Low Dose	Drug: CK-2017357 One 125 mg CK-2017357 tablet and two matching placebo tablets once daily for 14 days (Part A) or one 125 mg CK-2017357 tablet and two matching placebo tablets once daily for 14 days taken concurrently with 50 mg riluzole (Part B) Other Name: tirasemtiv
Experimental: Active Drug Mid Dose	Drug: CK-2017357 Two 125 mg CK-2017357 tablets and one matching placebo tablet once daily for 14 days (Part A) or two 125 mg CK-2017357 tablets and one matching placebo tablet once daily for 14 days taken concurrently with 50 mg riluzole (Part B)
Experimental: Active Drug High Dose	Drug: CK-2017357 Three 125 mg CK-2017357 tablets once daily for 14 days (Part A) or three 125 mg CK-2017357 tablets once daily for 14 days taken concurrently with 50 mg riluzole (Part B)

Detailed Description:

In Part A, approximately 24 patients will be randomized to one of four different treatment groups. After a 7-day washout of riluzole, patients in each treatment group will receive daily oral doses of placebo, 125 mg, 250 mg, or 375 mg of CK-2017357 for 14 days. Patients will take daily doses of CK-2017357 or placebo (Day 1 through Day 14) and will return to the study site on Day 2, Day 8 and Day 15. All patients will return for a follow-up visit 7 days (± 2 days) after their last dose.

In Part B, approximately 24 patients will be randomized to one of four different treatment groups as in Part A. Patients in Part B will be required to decrease their riluzole dose to 50 mg once a day (QD) for 7 days prior to randomization. After this 7 day period, patients will take riluzole at 50 mg QD concurrently with their morning dose of blinded study drug.
