Outcomes

Primary Outcomes

Change From Baseline in Forced (Expiratory) Vital Capacity (FVC) at Week 52

Time frame: Baseline, Week 52

Secondary Outcomes

Change From Baseline in FVC, Expressed in Percent Predicted at Week 52

FVC is the total amount of air exhaled during the forced expiratory volume test that is measured during spirometry and is the most important measurement of lung function. This test requires participant to breath into a tube connected to a machine that measures the amount of air that can be moved in and out of the lungs after taking an inhaled bronchodilator medicine which is used to dilate participant's bronchial (breathing) tubes. Percent predicted FVC (in %, here FVC was measured in litres) = \[(observed FVC)/(predicted FVC)\]\*100. Change from baseline is defined as post-baseline value minus baseline value. A negative change from baseline indicates decline.

Time frame: Baseline, Week 52

Time to Progression

Time to progression is defined by a composite endpoint, including any of the following events: Absolute decline of 10% predicted in FVC (FVC percent predicted (baseline) - FVC percent predicted (progression) ≥10%); Non-elective hospitalization for respiratory events; Lung transplantation or death. The earliest time to meet at least 1 composite criterion was calculated.

Time frame: Up to Week 60 (End of Study)

Time to First Acute Idiopathic Pulmonary Fibrosis (IPF) Exacerbation

Time to first acute IPF exacerbation is defined as time from randomization to the first occurrence of acute IPF exacerbation.

Participants were assessed according to the modified 2007 diagnostic criteria for acute IPF exacerbation.

Time frame: Baseline, Week 26 and Week 52

Number of Participants With Adverse Events (AEs) and Serious Adverse Events (SAEs)

An AE is any untoward medical occurrence in a participant administered a pharmaceutical product and that does not necessarily have a causal relationship with this treatment. An AE can therefore be any unfavorable and 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 SAE is any untoward medical occurrence that at any dose results in death, requires inpatient hospitalization, results in persistent or significant disability and/or results in a congenital anomaly.
