Study of Safety, Tolerability & Efficacy of CK-2017357 in Amyotrophic Lateral Sclerosis (ALS)

March 30, 2020 updated by: Cytokinetics

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)

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).

Study Overview

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

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.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
The Change From Baseline in ALS Functional Rating Scale-Revised (ALSFRS-R) Total Score to the Average of Values Obtained at the End of Weeks 8 and 12 of Double-blind Treatment
Time Frame: Baseline, 8 weeks, 12 weeks
The ALSFRS-R is used to measure the progression and severity of disease; it consists of 12 questions, assessing a patient's capability and independence in functional activities relevant to ALS, categorized in 4 domains: gross motor tasks, fine motor tasks, bulbar functions, and respiratory function. Each question is scored from 0 (indicating incapable or dependent) to 4 (normal). The total score ranges from 0 to 48, with higher scores reflecting more normal function and lower scores reflecting more impaired function.
Baseline, 8 weeks, 12 weeks

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Change From Baseline in Maximum Voluntary Ventilation (MVV) to the Average of Values Obtained at the End of Weeks 8 and 12 of Double-blind Treatment
Time Frame: Baseline, 8 weeks, 12 weeks
MVV was measured as the volume (in liters) of air that could be exhaled during 12 seconds of rapid deep breathing; for analysis purposes, the measured volume was extrapolated to 1 minute (to give units of L/min).
Baseline, 8 weeks, 12 weeks
Change From Baseline in Sniff Nasal Inspiratory Pressure (SNIP) to the Average of Values Obtained at the End of Weeks 8 and 12 of Double-blind Treatment
Time Frame: Baseline, 8 weeks, 12 weeks
SNIP was measured at functional residual capacity, the bottom of the tidal breathing cycle, through 1 plugged nostril while the other remained open. Inspiratory pressure is a negative number where a larger negative number represents . . . A forceful, maximal inspiratory sniff was performed and a peak pressure value reported. The best result (ie, the highest number) from 5 tests was recorded as the SNIP.
Baseline, 8 weeks, 12 weeks
Change From Baseline in Slow Vital Capacity (SVC) to the Average of Values Obtained at the End of Weeks 8 and 12 of Double-blind Treatment
Time Frame: Baseline, 8 weeks, 12 weeks
SVC was measured using a spirometer (in units of liters). Following 3 to 5 breaths at rest, the patients were instructed to take as deep an inspiration as possible followed by a maximum exhalation (blowing out all the air in their lungs). Values obtained were converted to % predicted values (ie, the test result as a percent of predicted values for the patients of similar demographic and baseline characteristics [eg, height, age, sex]).
Baseline, 8 weeks, 12 weeks
Change From Baseline in Maximum Handgrip Strength in the Weaker Hand to the Average of Values Obtained at the End of Weeks 8 and 12 of Double-blind Treatment
Time Frame: Baseline, 8 weeks, 12 weeks
Maximum handgrip strength was measured using an electronic hand dynamometer; patients were asked to squeeze the device with the maximum possible force.
Baseline, 8 weeks, 12 weeks
Change From Baseline in Handgrip Fatigability (at 60% of Target in the Weaker Hand) to the Average of Values Obtained at the End of Weeks 8 and 12 of Double-blind Treatment
Time Frame: Baseline, 8 weeks, 12 weeks
Handgrip fatigability was measured immediately following determination of maximum handgrip strength (via an electronic hand dynamometer). Once maximum handgrip strength was achieved, the force of the grip was timed for 2 minutes or until the grip strength had dropped to 60% of the maximum, whichever came first.
Baseline, 8 weeks, 12 weeks
Change From Baseline in Muscle Strength Mega-Score Based on Percent Change in Muscle Strength Measurements to the Average at the End of Weeks 8 and 12 of Double-blind Treatment
Time Frame: Baseline, 8 weeks, 12 weeks
A hand-held dynamometer (HHD), with a scale of 0 to 300 pounds, was used to measure muscle strength and handgrip strength (bilateral); the muscle groups tested were: elbow flexion (bilateral), wrist extension (bilateral), knee extension (bilateral), and ankle dorsiflexion (bilateral). For each assessment time point, the percent change from baseline was calculated for each muscle group and handgrip strength. The muscle strength mega-score was calculated as the average of the changes (ie, percent change from baseline) observed for each muscle groups as well as handgrip strength. For this endpoint, negative values indicate a decline in muscle strength.
Baseline, 8 weeks, 12 weeks
