Evaluating Respiratory Symptoms (E-RS)
11-item E RS collected as part of the 14-item EXAcerbations of Chronic pulmonary disease Tool (EXACT PRO®) scale, with data from the additional 3 items from the EXACT PRO scale used for exploratory purposes only. The PSB will be calculated as the mean of the E-RS scores collected in the -35 to -6 days prior to RV symptom onset. If the E-RS score has not returned to PSB at the time of Day 28 Visit, the participant will complete the E-RS daily until Day 42. The questions are asked about how the participant feels today and will be collected at night.
Time frame: Baseline Period/Asymptomatic Phase: Daily for 12 weeks Treatment/Follow-Up Periods: Daily for up to 42 days
Patient Global Impression of Severity (PGIS)
The PGIS is one question, 'Please rate the overall severity of your respiratory symptoms today? (none, mild, moderate, severe, very severe).'
Time frame: Baseline Period/Asymptomatic Phase: Daily for 12 weeks Treatment/Follow-Up Periods: Daily for up to 42 days
Wisconsin Upper Respiratory Symptom Survey - 11
The questions are asked about how the participant feels today or within the last 24 hours. The questionnaire will be completed at night.
Time frame: Treatment/Follow-up Periods: Daily for 28 days
Change from Baseline in Respiratory System Resistance at 5 Hz (R5) Measured by Oscillometry
Respiratory system resistance at an oscillation frequency of 5 Hz, measured by oscillometry during unforced tidal breathing. R5 reflects total respiratory system resistance and is a measure of overall airway caliber. Values are reported as the mean of at least three technically acceptable measurements, performed according to the 2020 European Respiratory Society / American Thoracic Society technical standards for respiratory oscillometry. Unit of measure: cmH₂O·s/L.
Time frame: Screening Visit, Day 1, Day 3, Day 7, Day 14, Day 28, Day 42

Change from Baseline in Respiratory System Resistance at 20 Hz (R20) Measured by Oscillometry
Respiratory system resistance at an oscillation frequency of 20 Hz, measured by oscillometry during unforced tidal breathing. R20 predominantly reflects large/central airway resistance, as higher-frequency oscillations do not penetrate the peripheral airways. Values are reported as the mean of at least three technically acceptable measurements, performed according to the 2020 European Respiratory Society / American Thoracic Society technical standards for respiratory oscillometry. Unit of measure: cmH₂O·s/L.
Time frame: Screening Visit, Day 1, Day 3, Day 7, Day 14, Day 28, Day 42
Change from Baseline in Frequency Dependence of Resistance (R5-R20) Measured by Oscillometry
The difference between respiratory system resistance measured at 5 Hz and at 20 Hz (R5 minus R20), measured by oscillometry during unforced tidal breathing. R5-R20 is interpreted as an index of small airway dysfunction, with elevated values indicating heterogeneity of peripheral airway resistance. Values are calculated from the mean of at least three technically acceptable measurements at each frequency, performed according to the 2020 European Respiratory Society / American Thoracic Society technical standards for respiratory oscillometry. Unit of measure: cmH₂O·s/L.
Time frame: Screening Visit, Day 1, Day 3, Day 7, Day 14, Day 28, Day 42
Change from Baseline in Respiratory System Reactance at 5 Hz (X5) Measured by Oscillometry
Respiratory system reactance at an oscillation frequency of 5 Hz, measured by oscillometry during unforced tidal breathing. X5 represents the elastic and inertive properties of the respiratory system at low frequency and becomes more negative with increased peripheral airway obstruction or reduced lung compliance. Values are reported as the mean of at least three technically acceptable measurements, performed according to the 2020 European Respiratory Society / American Thoracic Society technical standards for respiratory oscillometry. Unit of measure: cmH₂O·s/L.
Time frame: Screening Visit, Day 1, Day 3, Day 7, Day 14, Day 28, Day 42
Change from Baseline in Area Under the Reactance Curve (AX) Measured by Oscillometry
The integrated area of the reactance curve from 5 Hz to the resonant frequency, measured by oscillometry during unforced tidal breathing. AX reflects the total elastic and inertive load of the respiratory system and is a sensitive composite index of peripheral airway dysfunction. Values are reported as the mean of at least three technically acceptable measurements, performed according to the 2020 European Respiratory Society / American Thoracic Society technical standards for respiratory oscillometry. Unit of measure: cmH₂O/L.
Time frame: Screening Visit, Day 1, Day 3, Day 7, Day 14, Day 28, Day 42
Change from Baseline in Resonant Frequency (Fres) Measured by Oscillometry
The oscillation frequency at which respiratory system reactance equals zero, measured by oscillometry during unforced tidal breathing. Fres represents the frequency at which the inertive and elastic forces of the respiratory system are equal in magnitude and opposite in direction; it shifts to higher frequencies with peripheral airway obstruction. Values are reported as the mean of at least three technically acceptable measurements, performed according to the 2020 European Respiratory Society / American Thoracic Society technical standards for respiratory oscillometry. Unit of measure: Hz.
