What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Change From Baseline in Percent Predicted Trough Forced Expiratory Volume in 1 Second (FEV1) After 4 Weeks of Treatment	Trough FEV1 was measured within 30 minutes prior to dosing of study medication.	At 30 minutes prior to dosing in Day 1 (baseline) and Day 29 (end of 4-week treatment period).

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Change From Baseline in Lung Clearance Index (LCI) Assessed by N2 Multiple Breath Washout (N2MBW) Procedure After 4 Weeks of Treatment	Change from baseline in Lung Clearance Index (LCI) assessed by N2 Multiple Breath Washout (N2MBW) procedure after 4 weeks of treatment was reported. LCI was calculated as the ratio of cumulative expired volume (CEV) to functional residual capacity (FRC), which was LCI = CEV (milliliter/kilogram) / FRC (milliliter/kilogram) and hence, LCI was "Unitless". The change from baseline after 4 weeks of treatment in LCI was then calculated as the LCI value measured after 4 weeks of treatment at Day 29 minus the LCI value measured at baseline on Day 1.	At pre-dose in Day 1 (baseline) and Day 29 (end of 4-week treatment period).
Change From Baseline in Cystic Fibrosis Questionnaire Revised (CFQ-R) Total Score After 4 Weeks of Treatment	The adult/adolescent format of the CFQ-R consists of 50 questions (qts) dividing into 12 domains: Physical functioning(8 qts), role limitations(4 qts), vitality(4 qts), emotional functioning(5 qts), social functioning(6 qts), body image(3 qts), eating disturbance(3 qts), treatment burden(3 qts), health perceptions(3 qts), weight(1 qts), respiratory symptoms(7 qts), and digestive system(3 qts). The score of some qts is first reversed if reversed coded, so that the score for each of the 50 qts ranges from 1 to 4 points (less symptoms). Then, a domain score for a domain with N qts is calculated as (sum of the scores of the N qts - N)/(N ✕ 4 - N) ✕ 100. Each domain score ranges from 0 to 100 (better health). The CFQ-R total score is summing up the domain scores and ranges from 0 to 1200 (better quality of life). The change from baseline in Cystic Fibrosis Questionnaire Revised (CFQ-R) total score after 4 weeks of treatment was reported.	At Day 1 (baseline) and Day 29 (end of 4-week treatment period).
Change From Baseline in Cough and Sputum Assessment Questionnaire (CASA-Q) (4 Separate Sub-scores) After 4 Weeks of Treatment	The 20-item Sputum Assessment Questionnaire (CASA-Q) consisted of 4 domains: Cough Symptoms Domain (3 items), Cough Impact Domain (8 items), Sputum Symptoms Domain (3 items), and Sputum Impact Domain (6 items). Score of each item has been reversed such that better responses have higher score, which ranges from 1 (worse) to 5 (better health). For each domain, the domain score was calculated by summing up the scores of the respective items and scaling to a value ranging from 0 to 100, with higher score associated with fewer symptoms/less impact due to cough or sputum. The 4 domain scores (sub-scores) were reported.	At Day 1 (baseline) and Day 29 (end of 4-week treatment period).
Percentage of Patients With Treatment-emergent Adverse Events (AE) up to Day 36	Percentage of patients with any treatment-emergent Adverse Events (AE) up to day 36 was reported.	From Day 1 (baseline) until end of 4 weeks of treatment period (Day 29) plus 7 days of follow-up, up to 36 days.
Concentration of BI 1265162 in Plasma at 0.083 Hour at Steady State Following Dose 15 (C0.083,ss,15)	Concentration of BI 1265162 in plasma at 0.083 hour at steady state following dose 15 (C0.083,ss,15) was reported.	At 5 minutes (around 0.083 hours) post dosing at steady state on Day 8 for dose 15 (morning dose on Day 8).
Concentration of BI 1265162 in Plasma at 0.083 Hour at Steady State Following Dose 57 (C0.083,ss,57)	Concentration of BI 1265162 in plasma at 0.083 hour at steady state following dose 57 (C0.083,ss,57) was reported.	At 5 minutes (around 0.083 hours) post dosing at steady state on Day 29 for dose 57 (morning dose on Day 29).
Pre-dose Concentration Measured of BI 1265162 in Plasma at Steady State After Dose 15 (Cpre,ss, 15)	Pre-dose concentration measured of BI 1265162 in plasma at steady state after dose 15 (Cpre,ss, 15) was reported.	At pre-dose (taken within 60 minutes prior to dosing) at steady state on Day 8 for dose 15 (morning dose on Day 8).
Pre-dose Concentration Measured of BI 1265162 in Plasma at Steady State After Dose 57 (Cpre,ss, 57)	Pre-dose concentration measured of BI 1265162 in plasma at steady state after dose 57 (Cpre,ss, 57) was reported.	At pre-dose (taken within 60 minutes prior to dosing) at steady state on Day 29 for dose 57 (morning dose on Day 29).
Area Under the Concentration-time Curve of BI 1265162 in Plasma From 0 to 4 Hours at Steady State After Dose 15 (AUC0-4,ss,15)	Area under the concentration-time curve of BI 1265162 in plasma from 0 to 4 hours at steady state after dose 15 (AUC0-4,ss,15) was reported.	At pre-dose (taken within 60 minutes prior to dosing) and 5 minutes (min), 30 min, 1 hour, and 4 hours post dosing at steady state on Day 8 for dose 15 (morning dose on Day 8).
