Masking: Double


Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Canakinumab<br>Participants received an initial dose of 1 mg/kg canakinumab (ACZ885) via intravenous infusion. Four weeks later, participants received a dose of 3 mg/kg canakinumab, and another dose of 3 mg/kg two weeks later. Thereafter, participants received doses of 6 mg/kg every four weeks until completion of the 45-week treatment period. | Drug: Canakinumab<br>* The dose of canakinumab (ACZ885) administered was individualized, based on the subject's weight pre-dose, and was administered via intravenous infusion.<br>|
| Placebo Comparator: Placebo<br>Participants received a matching placebo intravenous infusion at weeks 1, 5, 7, and thereafter every four weeks until completion of the 45-week treatment period. | Drug: Placebo<br>* Matching placebo to ACZ885 administered via intravenous infusion.<br>|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change From Baseline in Forced Expiratory Volume in 1 Second (FEV1) | Forced expiratory volume in 1 second (FEV1) is the amount of air that can be exhaled in one second. FEV1 was measured by spirometry performed at approximately the same time of day on each visit to avoid diurnal variation. All spirometry calibrations and evaluations followed the recommendations of the American Thoracic Society / European Respiratory Society guidelines for acceptability. A positive change from baseline in FEV1 indicates improvement in lung function. | Baseline, Week 25 and Week 45 | 
| Change From Baseline in Forced Expiratory Volume in 1 Second Percent Predicted | The FEV1 percent predicted expresses FEV1 as a percentage of the predicted values for participants of similar characteristics (height, age, sex, and sometimes race and weight). A positive change from baseline in FEV1 % predicted indicates improvement in lung function. | Baseline, Week 25 and Week 45 | 
| Change From Baseline in Forced Vital Capacity (FVC) | Forced Vital Capacity is the amount of air which can be forcibly exhaled from the lungs after taking the deepest breath possible. FVC was assessed by spirometry. A positive change from baseline in FVC indicates improvement in lung function. | Baseline, Week 25 and Week 45 | 
| Change From Baseline in Slow Vital Capacity (SVC) | Vital Capacity is the amount of air that can be forcibly exhaled from the lungs after a full inhalation. Slow Vital Capacity (SVC) test is performed by having the patient slowly and completely blow out all of the air from their lungs. A positive change from baseline in SVC indicates improvement in lung function. | Baseline, Week 25 and Week 45 | 
| Change From Baseline in Forced Expiratory Flow 25% to 75% | The forced expiratory flow (FEF) 25%-75% measurement describes the amount of air expelled from the lungs during the middle half (25% - 75%) of the forced vital capacity test and is measured using spirometry. A positive change from baseline in FEF indicates improvement in lung function. | Baseline, Week 25 and Week 45 | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Number of Participants Who Experienced Serious Adverse Events or Discontinued Due to Adverse Events | Safety was assessed by the number of participants with serious adverse events and/or adverse events leading to study discontinuation. A summary of adverse events is presented with this outcome, additional details are provided in the Adverse Events section. | Adverse events were collected during the 45 week treatment period and the 12 week follow-up period. |
