Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change in 24-hour Objective Cough Frequency (Log Normalized Percent Change Relative to Placebo)	Change in 24-hour objective cough frequency is total number of cough events during the monitoring period (24-hour interval)/24 (Total duration (in hours) for the monitoring period) which is captured through sound recordings by a custom-built digital recording device (VitaloJAK, Vitalograph, Ltd).	from Baseline to Day 84
Secondary	Change in Awake Objective Cough Frequency	Awake cough frequency = (total number of cough events during the monitoring period (24-hour interval) the subject is awake)/(Total duration (in hours) for the monitoring period the subject is awake) which is captured by a custom-built digital recording device (VitaloJAK, Vitalograph, Ltd).	from Baseline to Day 84
Secondary	Percentage of Participants With = 30% Reduction in 24-hour Objective Cough Frequency	The percentage of participants with = 30% of reduction from baseline in 24-hour cough frequency is the number of participants with =-30% change in 24-hour cough frequency divided by the total number of participants with available data. This data is captured by a custom-built digital recording device (VitaloJAK, Vitalograph, Ltd).	from Baseline to Day 84
Secondary	Percentage of Participants With =30% Reduction in Awake Objective Cough Frequency	The percentage of participants with = 30% of reduction from baseline in the awake cough frequency is the number of participants with =30% change in awake cough frequency divided by the total number of participants with available data. This data is captured by a custom-built digital recording device (VitaloJAK, Vitalograph, Ltd).	from Baseline to Day 84
Secondary	Change From Baseline in Cough Severity Visual Analog Scale (VAS)	Visual Analog Scale (VAS) 101-point scale ranging from 0 (no cough) to 100 (worst cough). A higher score corresponds to higher cough severity.	from Baseline to Day 84
