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

Forced vital capacity (FVC) is the total amount of air exhaled during the lung function test.

For this endpoint reported means represent the adjusted rate.

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).

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 .

Means provided are the adjusted means and are based on all analysed patients in the model (not only patients with a change from baseline to week 52).

Percentage change from baseline in FVC over 52 weeks. Means provided are the adjusted means and are based on all analysed patients in the model (not only patients with a change from baseline to week 52).

Means provided are the adjusted means and are based on all analysed patients in the model (not only patients with a change from baseline to week 52).

Percentage change from baseline in FVC (% predicted) at 52 weeks. Means provided are the adjusted means and are based on all analysed patients in the model (not only patients with a change from baseline to week 52).

Absolute categorical change of FVC (% predicted) by categories over 52 weeks - 5% threshold (decrease by >5%, increase by >5%, and change within ≤5%).

Absolute categorical change of FVC (% predicted) by categories over 52 weeks - 10% threshold (decrease by 10%, increase by >10%, and change within ≤10%)

FVC responders using 10% threshold at 52 weeks, defined as patients with absolute decline in FVC% predicted no greater than 10% and with an FVC evaluation at 52 weeks.

Proportion of FVC responders using 5% threshold at 52 weeks, defined as patients with absolute decline in FVC% predicted no greater than 5% and with an FVC evaluation at 52 weeks.

Proportion of SGRQ responders at 52 weeks.

Responders defined as <= -4 points change in change from baseline in SGRQ total score at 52 weeks.

SGRQ Symptom score is a sub-component of SGRQ total score and is concerned with the effect of respiratory symptoms, their frequency and severity. This score calculated as summed weights ranges from 0 to 100 with lower score denoting a better symptom-related quality of life.

Means presented are the adjusted means and are based on all analyzed patients in the model (not only patients with a baseline and measurement at week 52).

SGRQ Impact score is a sub-component of SGRQ total score and covers a range of aspects concerned with social functioning and psychological disturbances resulting from airway disease. This score calculated as summed weights ranges from 0 to 100 with lower score denoting a better impact-related quality of life.

Means presented are the adjusted means and are based on all analyzed patients in the model (not only patients with a baseline and measurement at week 52).

SGRQ Activity score is a sub-component of SGRQ total score and concerned with activities that cause or are limited by breathlessness. This score calculated as summed weights ranges from 0 to 100 with lower score denoting a better activity-related quality of life.

Means presented are the adjusted means and are based on all analyzed patients in the model (not only patients with a baseline and measurement at week 52).

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.

Shortness of Breath Questionnaire measures the shortness of breath. It comprises of 24 items. Each item is scored on a scale between 0-5 where 5 represents maximal breathlessness. The responses to all items are summed up to provide the overall score that can range from 0 (best outcome) to 120 (worst outcome).

Means presented are the adjusted means and are based on all analyzed patients in the model (not only patients with a baseline and measurement at week 52).

The cough domains of the Cough and Sputum Assessment Questionnaire (CASAQ(CD)) assess the frequency and severity of cough and sputum and their impact on everyday life. It contains 4 domains cough/sputum symptom and impact with each scale ranging from 0 to 100 with lower scores indicating higher symptoms/impact levels (worst outcome).

Means presented are the adjusted means and are based on all analyzed patients in the model (not only patients with a baseline and measurement at week 52).

The cough domains of the Cough and Sputum Assessment Questionnaire (CASA- Q) assess the frequency and severity of cough and sputum and their impact on everyday life. It contains 4 domains cough/sputum symptom and impact with each scale ranging from 0 to 100 with lower scores indicating higher symptoms/impact levels (worst outcome).

Means presented are the adjusted means and are based on all analyzed patients in the model (not only patients with a baseline and measurement at week 52).

Patient's Global Impression of Change (PGI-C) responders are defined as 'Very much better'/ 'Much better'/ 'A little better'/ 'No change'.

The EuroQol 5-dimensional Health State is based on a visual analog scale (EQ-VAS) representing the general patient's health state labelled from 100 (best imaginable health state) to 0 (worst imaginable health state). A higher score indicating a better health state. Change from baseline is calculated as the difference between health state at week 12, 24 and 52 respectively and health state at baseline as measured by the scale.

The incidence rate of exacerbations (calculated as the number of patients with at least 1 acute IPF exacerbation divided by the total number of years at risk in years*100)

Due to rare events, the median of time to event is not calculable, thus the percentages of patients who did or did not experienced death before or at 372 days after randomisation or last contact date (whichever occurs first) are reported.

Failure is the proportion of patients who died over 52 weeks (373 days time-period).

Due to rare events, the median of time to event is not calculable, thus the percentages of participants who did or did not experienced death due to respiratory causes before or at 372 days after randomisation or last contact date (whichever occurs first) are reported.

Failure is the the proportion of patients who died due to respiratory causes over 52 weeks (373 days time-period).

Due to rare events, the median of time to event is not calculable, thus the percentages of participants who did or did not die before or at last trial medication intake + 28 days were censored at last trial medication intake + 28 days and reported.

Failure is the the proportion of patients who died on-treatment.

Due to rare events, the median of time to event is not calculable, thus the percentages of participants who did or did not experience event (death or lung transplant) before or at 372 days after randomisation or last contact date (whichever occurs first) are reported. Failure is the proportion of patients who died or had lung transplant over 52 weeks (373 days time-period).

Due to rare events, the median of time to event is not calculable, thus the percentages of participants who did or did not experienced death or lung transplant or qualifying for lung transplant over 52 weeks are reported. A patient was considered qualifying for lung transplant by the investigator if he or she fulfilled the following criteria:

FVC <45% predicted or Carbon monoxide diffusion capacity (DL(CO)) <30% pred or Oxygen saturation on pulse oximetry (SpO2) <88% at rest, at sea level (to be adapted for other heights).

These criteria were evaluated by investigators judgement. Failure is the proportion of patients who died or had lung transplant or qualified for lung transplant over 52 weeks (373 days time-period).

Means presented are the adjusted means. Adjusted mean is based on all analyzed patients in the model (not only patients with a change from baseline to week 52)
