A Phase IIb, Multi-National, Double-Blind, Randomized, Placebo-Controlled Study to Evaluate the Safety, Tolerability and Efficacy of CK-2017357 in Patients With Amyotrophic Lateral Sclerosis (ALS) (BENEFIT-ALS)

Study Purpose:

The purpose of this research study is to evaluate the safety and effectiveness of CK-2017357 when taken with or without riluzole (also called Rilutek®) in patients with Amyotrophic Lateral Sclerosis (ALS).

Full Study Summary:

The length of the study, including screening, dosing, and follow-up, is approximately 20 weeks. After a one-week open-label phase during which all patients will receive CK-2017357 125 milligrams (mg) twice daily, patients who tolerate the open-label 125 mg of CK-2017357 will be randomized one to one (fifty-fifty) to receive double-blind CK-2017357 or matching placebo. The CK-2017357/placebo dose will be increased no faster than weekly to each patient's highest tolerated daily dose, with a maximum of 250 mg twice daily. The dose may be decreased based on tolerability. Patients will continue treatment at the highest tolerated dose to complete a total of 12 weeks of double-blind treatment. Patients may be on riluzole or not on riluzole at study entry. Patients not on riluzole must stay off riluzole. Patients on riluzole who are getting double-blind CK-2017357 will be given riluzole at half the labeled dosage (50 mg once a day instead of 50 mg twice a day). Blood tests for safety will be performed. Information about any side effects that may occur will also be collected.

4. Upright Slow Vital Capacity (SVC) >50 % of predicted for age, height and sex

5. At least 4 of the 12 ALSFRS-R questions must be scored 2 or 3

6. Diminished but measurable maximum voluntary grip strength in at least one hand; i.e., between 10 and 50 pounds (females) and 10 and 70 pounds (males)

10. Male patients must agree for the duration of the study and 10 weeks after the end of the study to use a condom during sexual intercourse with female partners who are of reproductive potential and to have female partners use an additional effective means of contraception (e.g., diaphragm plus spermicide, or oral contraceptives) or the male patient must agree to abstain from sexual intercourse during and for 10 weeks after the end of the study

11. Female patients must be post-menopausal (≥ 1 year) or sterilized, or, if of childbearing potential, not be breastfeeding, have a negative pregnancy test, have no intention to become pregnant during the course of the study, and use contraceptive drugs or devices as detailed in item 10 for the duration of the study and for 10 weeks after the end of the study

12. Patients must be either on a stable dose of riluzole 50 mg twice daily for at least 30 days prior to screening or have not taken riluzole for at least 30 days prior to screening and are willing not to begin riluzole use during the conduct of this study.

Exclusion Criteria:

1. Any use of non-invasive positive pressure ventilation (NIPPV, e.g. continuous positive airway pressure [CPAP] or bilevel positive airway pressure [BiPAP]) for any portion of the day, or mechanical ventilation via tracheostomy, or on any form of oxygen supplementation
