Arm && Interventions

Group	Intervention	Description
BG00011	BG00011	Participants will receive BG00011 56 mg once weekly by subcutaneous (SC) injection for 52 weeks.
Placebo	Placebo	Participants will receive placebo once weekly by (SC) injection for 52 weeks.

Primary Outcome Measures

Name	Time	Method
Change From Baseline in Forced (Expiratory) Vital Capacity (FVC) at Week 52	Baseline, Week 52	FVC is the total amount of air exhaled during the forced expiratory volume test that is measured during spirometry and is the most important measurement of lung function. This test requires participant to breath into a tube connected to a machine that measures the amount of air that can be moved in and out of the lungs. Change from baseline is defined as post-baseline value minus baseline value. A negative change from baseline indicates decline.

Secondary Outcome Measures

Name	Time	Method
Time to Progression	Up to Week 60 (End of Study)	Time to progression is defined by a composite endpoint, including any of the following events: Absolute decline of 10% predicted in FVC (FVC percent predicted (baseline) - FVC percent predicted (progression) ≥10%); Non-elective hospitalization for respiratory events; Lung transplantation or death. The earliest time to meet at least 1 composite criterion was calculated.
Time to First Acute Idiopathic Pulmonary Fibrosis (IPF) Exacerbation	Up to Early Termination Visit (Up to Week 52)	Time to first acute IPF exacerbation is defined as time from randomization to the first occurrence of acute IPF exacerbation. Acute IPF exacerbation is defined as a clinically significant deterioration of unidentifiable cause in a participant with underlying IPF. The diagnostic criteria for IPF used in this study were derived from evidence-based guidelines developed by the American Thoracic Society/European Respiratory Society/Japanese Respiratory Society/Latin American Thoracic Association (ATS/ERS/JRS/ALAT) joint task force for the diagnosis and management of IPF. Participants were assessed according to the modified 2007 diagnostic criteria for acute IPF exacerbation.

Number of Participants With Adverse Events (AEs) and Serious Adverse Events (SAEs)	Up to Week 60 (End of Study)	An AE is any untoward medical occurrence in a participant administered a pharmaceutical product and that does not necessarily have a causal relationship with this treatment. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a medicinal (investigational) product, whether or not related to the medicinal (investigational) product. An SAE is any untoward medical occurrence that at any dose results in death, requires inpatient hospitalization, results in persistent or significant disability and/or results in a congenital anomaly.
