Safety and Efficacy of BIBF 1120 at High Dose in Idiopathic Pulmonary Fibrosis Patients

Change From Baseline in Saint-George's Respiratory Questionnaire (SGRQ) Total Score at 52 Weeks

This is a key secondary endpoint. SGRQ is a health-related quality of life questionnaire divided into 3 components : symptoms, activity and impact. The total score (summed weights) can range from 0 to 100 with a lower score denoting a better health status. Means provided are the adjusted means based on all analyzed patients in the model (not only patients with a baseline and measurement at week 52).

Time frame: baseline and 52 weeks

Time to First Acute Idiopathic Pulmonary Fibrosis (IPF) Exacerbation

Due to rare events, the median of time to event is not calculable, thus the percentages of patients with (IPF) exacerbation are reported and represented as a key secondary endpoint. An acute exacerbation (reported as an AE by the investigator) was defined as follows: Otherwise unexplained clinical features including all of the following: * Unexplained worsening or development of dyspnoea within 30 days * New diffuse pulmonary infiltrates on chest X-ray, and/or new HRCT parenchymal abnormalities with no pneumothorax or pleural effusion (new ground-glass opacities) since the last visit * Exclusion of infection as per routine clinical practice and microbiological studies * Exclusion of alternative causes as per routine clinical practice including left heart failure, pulmonary embolism and identifiable cause of acute lung injury. Failure is the proportion of patients with at least one acute IPF exacerbation over 52 weeks, based on all investigator-reported AEs .

Change From Baseline in Idiopathic Pulmonary Fibrosis (IPF) Specific Version of SGRQ (SGRQ-I) Total Score at 52 Weeks (Points): Patient Reported Outcomes (PROs)

SGRQ-I is the IPF specific version of SGRQ comprises of selected items from the SGRQ divided into three components, Symptoms, Activity and Impact. Each component is scored separately. The weights for all items with a positive responses are summed and the weights from missed items are deducted from the maximum possible weight for the total score. The total score is calculated by dividing the summed weights from positive items in the questionnaire by maximum possible weight for all items in the questionnaire. The total score can range from 0 to 100 with a lower score denoting a better health-related quality of life. Change from baseline is calculated as the difference between total score at week 52 and total score at baseline as measured by the scale.
