Brief Summary:
The purpose of this study was to assess the effect of CK-2127107 (hereafter referred to as reldesemtiv) versus placebo on respiratory function and other measures of skeletal muscle function in patients with ALS.
| Condition or disease | Intervention/treatment | Phase |
|---|---|---|
| Amyotrophic Lateral Sclerosis | Drug: Reldesemtiv Drug: Placebo | Phase 2 |
This was a double-blind, randomized, placebo-controlled, dose ranging study of reldesemtiv in patients with ALS. Eligible patients were randomized (1:1:1:1) to receive placebo or one of three doses of reldesemtiv (150, 300, or 450 mg twice daily) for 12 weeks. Randomization was stratified by riluzole concomitant use/non-use and edaravone concomitant use/non-use. Concomitant riluzole and edaravone were allowed as long as the riluzole dose had been stable for at least 30 days prior to screening and edaravone had been taken for 2 cycles prior to screening; these drugs could not be initiated during the study.
A total of 7 study visits were planned: screening, Day 1 (first dosing day), Weeks 2, 4, 8, and 12, and follow-up (4 weeks after the last dose of study drug). Study drug (placebo or reldesemtiv) was to be taken twice daily, approximately 12 hours (± 2 hours) apart and within 2 hours following a meal.

Primary Outcome Measures :
- Change From Baseline to Week 12 in the Percent Predicted Slow Vital Capacity (SVC) [ Time Frame: Baseline to Week 12 ]Slow vital capacity was measured using a spirometer (in units of liters). Following 3 to 5 breaths at rest, 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 percent predicted values using the Global Lung Initiative equation (ie, the test result as a percent of predicted values for patients of similar demographic and baseline characteristics [eg, height, age, sex]).
Secondary Outcome Measures :
- Change From Baseline to Week 12 in the ALS Functional Rating Scale - Revised (ALSFRS-R) Total Score [ Time Frame: Baseline to Week 12 ]The ALSFRS-R is used to measure the progression and severity of disability in patients with ALS. The ALSFRS-R consists of 12 questions, assessing a patient's capability and independence in functional activities relevant to ALS, categorized in the following 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. Higher scores reflect more normal function and lower scores reflect more impaired function.
- Slope of Muscle Strength Mega-score From Baseline to Week 12 [ Time Frame: Baseline to Week 12 ]A hand-held dynamometer, 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, wrist extension, first dorsal interosseous, hip flexion, knee extension, and ankle dorsiflexion; all muscle groups were evaluated bilaterally. For each postbaseline assessment of muscle strength, the percent change from baseline was calculated for each muscle group and handgrip strength, using the following equation: ([postbaseline value - baseline value] / baseline value) × 100. The muscle-strength mega-score was calculated as the average of the changes (ie, percent change from baseline) observed for each of the muscle groups as well as handgrip strength. For this endpoint, negative values indicate a decline in muscle strength.
