Relative Change From Baseline in Evaluating Respiratory Symptoms in Idiopathic Pulmonary Fibrosis (E-RS:IPF) Cough Subscale at Week 6
Prazo: Baseline, Week 6
The E-RS:IPF is a respiratory symptom subscale of the exacerbation of chronic pulmonary disease tool (EXACT) and consists of 11 items and was developed for use in IPF. The Cough subscale includes a single item (item 2: How often did you cough today?). The possible score range is 0 (not at all) to 4 (almost constantly). Higher scores indicate more severe symptoms. The relative change from baseline values is presented below. The relative change from baseline = [ (Post-baseline - Baseline) / Baseline] × 100. A positive change from baseline indicates worsening. The baseline value was defined as the last non-missing observation prior to the date of the first dose of study.
Baseline, Week 6
Number of Participants Who Experienced at Least One Treatment Emergent Adverse Events (TEAEs)
Prazo: Up to Week 12
An adverse event (AE) was defined as any untoward medical occurrence in a participant or clinical investigation participant administered a pharmaceutical product and which does not necessarily have to have a causal relationship with the treatment. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding, for example), symptom, or disease temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product. A TEAE was defined as any AE that occurs after the first dose of study drug. TEAEs included both serious and non-serious TEAEs.
Up to Week 12
Relative Change From Baseline in 24-hour Cough Frequency at Week 6
Prazo: Baseline, Weeks 6
Relative change in 24-hour (combined daytime and nighttime) cough frequency (coughs per hour) from baseline was assessed. Assessment was done using objective digital cough monitoring.

Change From Baseline in Leicester Cough Questionnaire (LCQ) Total Score at Week 6
Prazo: Baseline, Week 6
LCQ is a self-reporting quality of life measure of chronic cough. It consists of 19 items with a 7-point Likert response scale ranging from 1 to 7. The responses are as follows: 1 = all of the time, 2 = most of the time, 3 = a good bit of the time, 4 = some of the time, 5 = a little of the time, 6 = hardly any of the time, and 7 = none of the time. Each item is designed to assess cough symptoms and the impact of cough across three main domains, physical (8 items), psychological (7 items), and social (4 items). Domain scores are calculated as the total score from items in the domain divided by the number of items in the domain and range from 1 to 7. The LCQ total score is calculated by summing the individual domain scores and ranges from 3 to 21, with higher scores indicating better health status. The baseline value was defined as the last non-missing observation prior to the date of the first dose of study.

The EQ-5D-5L is a participant reported outcome and comprises of a descriptive system with 5 dimensions (mobility, self-care, usual activities, pain/discomfort, and anxiety/depression). The recall period was the day that the questions were being completed. Each of the 5 dimensions in the descriptive system had 5 levels: 1 = no problems, 2 = slight problems, 3 = moderate problems, 4 = severe problems, and 5 = extreme problems. Higher scores indicate worsening. The baseline value was defined as the last non-missing observation prior to the date of the first dose of study.
