Efficacy and Safety of Nintedanib in Patients With Progressive Fibrosing Interstitial Lung Disease (PF-ILD)

King's Brief Interstitial Lung Disease questionnaire (K-BILD) consists of 15 items and 3 domains: breathlessness and activities, psychological, and chest symptoms. Possible score ranges from 0-100, score of 100 representing the best health status. If missing items were >50% per domain, the domain score was set to missing. If any of the domain scores were missing, the total score was set to missing. Absolute change from baseline in K-BILD Total score at week 52 in the overall population was based on a Mixed Model Repeated Measures (MMRM), with fixed effects for baseline K-BILD Total score, HRCT fibrotic pattern, visit, treatment-by-visit interaction, baseline-by-visit interactions and random effect for participant. Visit was the repeated measure. Within-participant errors were modelled by unstructured variance-covariance matrix.

Absolute change from baseline in K-BILD Total score at week 52 in participants with HRCT fibrotic pattern=UIP-like fibrotic pattern only was based on a Mixed Model Repeated Measures (MMRM), with fixed effects for baseline K-BILD Total score, HRCT fibrotic pattern, visit, treatment-by-visit interaction, baseline-by-visit interactions and random effect for participant. Visit was the repeated measure. Within-participant errors were modelled by unstructured variance-covariance matrix.

Time to first acute ILD exacerbation or death over 52 weeks was defined as time to first acute ILD exacerbation or death due to any cause within the first 52 weeks and was computed as earliest of date of first documented acute ILD exacerbation or death - date of first drug intake + 1. Participants alive who did not experience any ILD exacerbation event or with unknown status within the first 52 weeks were censored.

Participants alive who did not experience any ILD exacerbation event or with unknown status within the first 52 weeks were censored.

Time to death over 52 weeks defined as the time from date of first drug intake until date of death from any cause for participants with known date of death (from any cause) within the first 52 weeks. Participants with no event (death from any cause) or unknown status within the first 52 weeks were censored.

Time to death over 52 weeks defined as the time from date of first drug intake until date of death from any cause for participants with known date of death (from any cause) within the first 52 weeks. Participants with no event (death from any cause) or unknown status within the first 52 weeks were censored.

Time to death due to respiratory cause over 52 weeks is defined as the time from date of first drug intake until date of death attributed to respiratory causes (determined by an independent Adjudication Committee) for participants with known date of death (from respiratory causes) within the first 52 weeks. Participants with no event (death from respiratory causes) or unknown status within the first 52 weeks were censored. As less than 4.95% of the total of participants in the analysis population experienced an event, only descriptive statistics were performed, as pre-specified.

Time to progression or death over 52 weeks is defined as the time from date of first drug intake to date of progression, or date of death (from any cause) if a participant died earlier. Participants with no event (progression or death from any cause) or unknown status were censored. Date of progression is defined as the date when ≥ 10% of absolute decline in FVC percent predicted compared to baseline occured for the first time. Forced Vital Capacity (FVC) is the volume of air (measured in milliliter) which can be forcibly exhaled from the lungs after taking the deepest breath possible. Predicted normal values of FVC were calculated according to the Global Lung Initiative. FVC percent predicted (FVC % pred) is the FVC divided by its predicted value in percent.

Predicted normal values of FVC were calculated according to the Global Lung Initiative. FVC percent predicted (FVC % pred) is the FVC divided by its predicted value in percent. Participants with relative decline from baseline in FVC % pred greater than 10% at week 52 were those participants with a negative relative change from baseline in FVC % pred at week 52 the absolute value of which being greater than 10% and those participants with missing data (worst case analysis).

Living with Pulmonary Fibrosis (L-PF) questionnaire is a 44 item questionnaire with two modules Symptoms (23 items) and Impacts (21 items) where the symptoms module yields three domain scores dyspnea, cough and fatigue as well as a total symptoms score (impacts module yields a single impacts score). L-PF Symptoms dyspnea domain score (dyspnea score) ranges from 0-100, the higher the score the greater the impairment. If missing items were ≥50 % within a score, then the corresponding score was set to missing. Absolute change from baseline in dyspnea score at week 52 is based on a Mixed Model Repeated Measures, with fixed effects for baseline dyspnea score, HRCT fibrotic pattern, visit, treatment-by-visit interaction, baseline dyspnea score-by-visit interaction and random effect for participant, visit as repeated measure. The Adjusted mean is based on all analysed participants in the model (not only participants with a baseline and measurement at week 52).
