Registered outcomes10

Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.

ListOutcomeTime frameDescription
PrimaryExertional Dyspnea Intensity at Isotime Exercise.4 weeks
Intensity of dyspnea (defined as breathing discomfort) at a standardized time (isotime) during constant work rate exercise tests as measured by the modified 10-point Borg scale. A rating of 0 represents no dyspnea up to a maximum of 10: a smaller rating is therefore an improvement. Isotime was defined as the highest exercise time in minutes completed in both post-treatment tests.
SecondaryExercise Endurance Time4 weeksDuration of constant work rate cycle exercise at 75% of maximum
SecondaryInspiratory Capacity at Rest4 weeksMeasurements of pulmonary function included spirometry and body plethysmography. The resting inspiratory capacity (IC) values reported here are 90 minutes post-dose after 4 weeks of treatment.
SecondaryVentilation at Isotime Exercise4 weeksVentilation was measured during constant work rate exercise tests. Isotime was defined as the highest exercise time in minutes common to both post-treatment tests.
SecondaryIntensity of "Unpleasantness of Breathing" at Isotime Exercise4 weeks
Intensity rating (modified 10-point Borg scale) measured at a standardized time (isotime) during constant work rate exercise tests. A rating of 0 represents no "unpleasantness of breathing" up to a maximum of 10. An improvement would be noted as a decrease in the Borg scale rating. Isotime was defined as the highest exercise time in minutes common to both post-treatment tests.
SecondaryInspiratory Capacity at Isotime Exercise4 weeksMeasurements of inspiratory capacity (IC) were conducted during constant work rate exercise tests. Isotime was defined as the highest time in minutes completed in both post-treatment tests.
SecondaryDiaphragm Electromyogram (EMGdi) at Isotime Exercise4 weeks
EMGdi was measured during constant work rate exercise tests via a multipair-electrode esophageal catheter. EMGdi expressed as a percentage of its maximum is used as an index of inspiratory neural drive. Isotime was defined as the highest exercise time in minutes common to both post-treatment tests.
SecondaryTidal Esophageal Pressure (Pes) Swings at Isotime Exercise4 weeks
Tidal esophageal pressure (Pes) swings were measured via an esophageal balloon catheter during constant work rate exercise tests. Tidal Pes expressed relative to maximum is an index of respiratory effort. Isotime was defined as the highest exercise time in minutes common to both post-treatment tests.
SecondaryMean Expiratory Flow at Isotime Exercise4 weeksMean expiratory flow was measured during constant work rate exercise tests. Isotime was defined as the highest exercise time in minutes common to both post-treatment tests.
SecondaryForced Expiratory Volume in 1 Second (FEV1)4 weeksMeasurements of pulmonary function included spirometry and body plethysmography. Values reported are 90 minutes post-dose after 4 weeks of treatment.
