Brief Summary:

The purpose of this study was to assess the effect of CK-2127107 relative to placebo on cycle ergometer exercise tolerance, assessed as change from period baseline in constant work rate (CWR) endurance time, utilizing a breath-by-breath metabolic measurement system with integrated electrocardiogram (ECG). The time to intolerance was assessed by a stopwatch and verified from electronic recordings of the cycle ergometer.

This study assessed cardiopulmonary and neuromuscular effects of CK-2127107 relative to placebo; the effect of CK-2127107 on resting spirometry relative to placebo; the safety and tolerability of CK-2127107 as well as the pharmacokinetics of CK-2127107.

Primary Outcome Measures :
  1. Change From Period Baseline at Week 2 in Constant Work Rate (CWR) Endurance Time Relative to Placebo [ Time Frame: Baseline and week 2 of each treatment period ]
    The CWR defines how long it takes until the participant reaches symptom limitations while simultaneously being monitored and is called "CWR time to intolerance," which determined the "CWR endurance time". Positive change indicates an improvement from baseline (i.e., a favorable outcome).


Secondary Outcome Measures :
  1. Change From Period Baseline at Week 2 in Oxygen Uptake (VO2) [ Time Frame: Baseline and week 2 of each treatment period ]
    VO2 was defined as volume of O2 extracted from inspired air in a given period of time. VO2 was reported at isotime and peak exercise during CWR test.

  2. Change From Period Baseline at Week 2 in Ventilation (VE) [ Time Frame: Baseline and week 2 of each treatment period ]
    VE was defined as volume of gas exhaled from the lungs in 1 minute, also called 'ventilation' or 'minute ventilation. VE was reported at isotime and peak exercise during CWR test.

  3. Change From Period Baseline at Week 2 in Ventilatory Equivalent for Carbon Dioxide (VE/VCO2) [ Time Frame: Baseline and week 2 of each treatment period ]
    VE/VCO2 was a ratio of VE to VCO2. It is a dimensionless quantity. This ratio indicates how many liters of air exhaled were breathed to eliminate 1 liter of CO2. VE/VCO2 was reported at isotime and peak exercise during CWR test.

  4. Change From Period Baseline at Week 2 in Inspiratory Capacity (IC) Change From Peak to Rest [ Time Frame: Baseline and week 2 of each treatment period ]
    IC was defined as the volume of air that can be inspired after a normal expiration; it is the sum of the tidal volume (VT) and the IRV.

  5. Change From Period Baseline at Week 2 in Perceived Exertion for Dyspnea and Leg Discomfort (BORG CR10) [ Time Frame: Baseline and week 2 of each treatment period ]
    The Borg Scale (Borg CR10) is a simple 10-item method of rating perceived exertion and collects information on perceived exertion in an individual's rating of exercise intensity. Participants were asked to use this scale to rate the intensity of their breathing and leg discomfort before, during, and after exercise. Scores range from 0 (Complete Rest) to 10 (Extremely Hard (almost maximal)). BORG CR10 was reported at isotime and peak exercise during CWR test.

  6. Change From Period Baseline at Week 2 in Respiratory Exchange Ratio (RER) [ Time Frame: Baseline and week 2 of each treatment period ]
    The respiratory exchange ratio is equal to the VCO2 / VO2 [RER = VCO2 (L/min) / VO2 (L/min)]. RER was reported at isotime and peak exercise during CWR test.

  7. Change From Period Baseline at Week 2 in Carbon Dioxide Output (VCO2) [ Time Frame: Baseline and week 2 of each treatment period ]
    VCO2 was defined as volume of CO2 exhaled from the body per unit of time; also called the rate of elimination of CO2. VCO2 was reported at isotime and peak exercise during CWR test.

  8. Change From Period Baseline at Week 2 in End-tidal PCO2 (PETCO2) [ Time Frame: Baseline and week 2 of each treatment period ]
    PETCO2 was defined as partial pressure of carbon dioxide in the expired gas at the end of an exhalation. This represents the mean partial pressure of carbon dioxide in the pulmonary alveoli. PETCO2 was reported at isotime and peak exercise during CWR test.

  9. Change From Period Baseline at Week 2 in End-tidal PO2 (PETO2) [ Time Frame: Baseline and week 2 of each treatment period ]
    PETO2 was defined as Partial pressure of oxygen in the expired gas at the end of an exhalation. This represents the mean partial pressure of oxygen in the pulmonary alveoli. PETO2 was reported at isotime and peak exercise during CWR test.

  10. Change From Period Baseline at Week 2 in Tidal Volume (VT) [ Time Frame: Baseline and week 2 of each treatment period ]
    VT was defined as tidal volume is the volume of gas exhaled in each respiratory cycle. Tidal volume is typically measured as an average value over several respiratory cycles, and is expressed in liters. VT was reported at isotime and peak exercise during CWR test.

  11. Change From Period Baseline at Week 2 in Breathing Frequency (Bf) [ Time Frame: Baseline and week 2 of each treatment period ]
    Bf was defined as the number of breaths (i.e., an entire inspiratory and expiratory respiratory cycle) per minute. Bf was reported at isotime and peak exercise during CWR test.

  12. Change From Period Baseline at Week 2 in Inspiratory Capacity (IC) [ Time Frame: Baseline and week 2 of each treatment period ]
    IC was defined as the volume of air that can be inspired after a normal expiration; it is the sum of the VT and the IRV. IC was reported at isotime and peak exercise during CWR test.

  13. Change From Period Baseline to Week 2 in Inspiratory Reserve Volume (IRV) [ Time Frame: Baseline and week 2 of each treatment period ]
    The Inspiratory reserve volume was equal to VT - IC measured in liters [IRV (L) = VT (L) - IC (L)]. IRV was reported at isotime and peak exercise during CWR test.

  14. Change From Period Baseline at Week 2 in Ventilatory Reserve (VE/MVV) [ Time Frame: Baseline and week 2 of each treatment period ]
    VE/MVV provides the rate of expired ventilation to the capacity. VE/MVV was reported at isotime and peak exercise during CWR test.

  15. Change From Period Baseline at Week 2 in Heart Rate (HR) [ Time Frame: Baseline and week 2 of each treatment period ]
    HR was reported at isotime and peak exercise during CWR test.

    Activation of accessory respiratory muscles was assessed by electromyogram. Data was reported at peak and isotime.

  23. Number of Participants With Treatment Emergent Adverse Events [ Time Frame: From first dose of study drug up to 14 days after last dose of study drug (8 weeks) ]
    TEAEs were defined as any AE that started or worsened in severity after the first dose of study drug up to 14 days after the last dose of study drug. An AE was defined as any untoward medical occurrence in a participant administered a study drug or who had undergone study procedures and did not necessarily have a causal relationship with this treatment. An AE could therefore be any unintended sign (including an abnormal laboratory finding), symptom or disease temporally associated with the use of a medicinal (investigational) product, whether or not related to the medicinal (investigational) product. An abnormality identified during a medical test (e.g., laboratory parameter, vital sign, ECG data, physical examination) an AE only if the abnormality meets 1 of the following criteria: Induces clinical signs or symptoms, Requires active intervention, Requires interruption or discontinuation of study drug, The abnormality or test value is clinically significant in the opinion of the inves
