- Primary Outcome Measures
Name Time Method Annualized Rate of Decrease in Percent Predicted Forced Vital Capacity (FVC) Over 52 Weeks Baseline up to Week 52 (assessed at Baseline, Weeks 1, 4, 12, 24, 36, 44, and 52) Annualized rates of decrease (slope throughout time from baseline to Week 52) for percent predicted FVC was assessed and reported. FVC is a standard pulmonary function test. FVC is defined as the volume of air that can forcibly be blown out after full inspiration in the upright position, measured in liters. Predicted FVC is based on sex, age, and height of a person. Percent predicted FVC (in %) = \[(observed FVC)/(predicted FVC)\]\*100.
- Secondary Outcome Measures
Name Time Method Annualized Rate of Decline in 6-Minute Walk Test (6MWT) Distance Over 52 Weeks Baseline up to Week 52 (assessed at Baseline, Weeks 1, 4, 12, 24, 36, 44, and 52) Annualized rates of decline (slope throughout time from baseline to Week 52) in 6MWT was assessed and reported. 6MWT was the distance (in meters \[m\]) that a participant could walk in 6 minutes.
Annualized Rate of Decrease in FVC Over 52 Weeks Baseline up to Week 52 (assessed at Baseline, Weeks 1, 4, 12, 24, 36, 44, and 52) Annualized rates of decrease (slope throughout time from baseline to Week 52) in FVC (in milliliters per year \[mL/year\]) was assessed and reported. FVC is defined as the volume of air that can forcibly be blown out after full inspiration in the upright position.
Progression-Free Survival (PFS) Baseline up to the event of death from any cause, all cause hospitalization, or a decrease from baseline of >/=10% in FVC, whichever occurred first (up to Week 122) FVC is defined as the volume of air that can forcibly be blown out after full inspiration in the upright position, measured in liters. Predicted FVC is based on sex, age, and height of a person. Percent predicted FVC = \[(observed FVC)/(predicted FVC)\]\*100. PFS was defined as time from randomization to death from any cause, all cause hospitalization, or a decrease from baseline of \>/=10% in FVC, whichever occurred first. Participants without an event were censored at the last assessment during the double-blind treatment period. Any participant who underwent lung transplantation was censored at the date of the transplant. The median PFS was estimated using Kaplan-Meier method. 95% CI for median was computed using the method of Brookmeyer and Crowley.
Time to First Occurrence of SGRQ Total Score Worsening or Death From Any Cause Baseline up to the event of SGRQ total score worsening or death from any cause, whichever occurred first (up to Week 122) The SGRQ is a 50-item health-related QoL instrument that measured health impairment. The questionnaire contains 3 domains: symptoms, activity, and impacts. Items were assessed on various response scales, including a 5-point Likert scale and True/False scale. The SGRQ had a recall specification of 4 weeks. The SGRQ total score (summed weights) ranged from 0 to 100 with a lower score denoting a better health status. Time from randomization to first occurrence of an event of SGRQ total score worsening (defined as reaching minimal important difference \[MID\], that is, an increase in total score of \>/=7) or death from any cause was reported. The median time to event was estimated using Kaplan-Meier method. 95% CI for median was computed using the method of Brookmeyer and Crowley.

Predicted FVC is based on sex, age, and height of a person. Percent predicted FVC (in %) = \[(observed FVC)/(predicted FVC)\]\*100.
Time to First Occurrence of a >/=10% Absolute Decline in Percent Predicted FVC or Death From Any Cause Baseline up to the event of >/=10% absolute decline in percent predicted FVC or death from any cause, whichever occurred first (up to Week 122) FVC is defined as the volume of air that can forcibly be blown out after full inspiration in the upright position, measured in liters.

Time from randomization to first occurrence of an event of \>/=10% absolute decline in percent predicted FVC or death from any cause was reported. Participants without an event were censored at the last assessment during the double-blind treatment period. Any participant who underwent lung transplantation was censored at the date of the transplant. The median time to event was estimated using Kaplan-Meier method. 95% confidence interval (CI) for median was computed using the method of Brookmeyer and Crowley.

Elimination Half-Life (t1/2) of Lebrikizumab Pre-dose (Hour 0) at Weeks 1, 4, 12, 24, 36, 64, 76, 88, 104; and at 4, 12, and 18 weeks post-last dose (last dose = Week 104) Elimination half-life is the time measured for the plasma drug concentration to decrease by one-half during the elimination phase of the drug. Analysis was performed on PK-Evaluable Population. Participants who received lebrikizumab were only included in the analysis.
Percentage of Participants With Event of Death, All Cause Hospitalization, or a Decrease From Baseline of >/=10% in FVC Baseline up to the event of death from any cause, all cause hospitalization, or a decrease from baseline of >/=10% in FVC, whichever occurred first (up to Week 122) FVC is defined as the volume of air that can forcibly be blown out after full inspiration in the upright position, measured in liters. Predicted FVC is based on sex, age, and height of a person. Percent predicted FVC = \[(observed FVC)/(predicted FVC)\]\*100.
Annualized Rate of Decrease in A Tool to Assess Quality of Life in IPF (ATAQ-IPF) Questionnaire Total Score Over 52 Weeks Baseline up to Week 52 (assessed at Baseline, Weeks 1, 4, 12, 24, 36, 44, and 52) The ATAQ-IPF Version 3 was utilized that included 31 items within 5 domains: cough (6 items), dyspnea (7 items), exhaustion (6 items), emotional well-being (6 items), and independence (6 items). Each item was assessed on a scale ranging from 1 (Strongly disagree) to 4 (Strongly agree). The ATAQ-IPF had a recall specification of 2 weeks. Simple summation scoring was used to derive individual domain scores as well as a total score. ATAQ-IPF total score ranged from 31 to 124 with lower score indicating better quality of life (QoL). Annualized rates of decrease (slope throughout time from baseline to Week 52) in ATAQ-IPF questionnaire total score was assessed and reported.

Time to Respiratory-Related Hospitalization Baseline up to the event of respiratory-related hospitalization (up to Week 122) Time from randomization to first occurrence of an event of respiratory-related hospitalization was reported. Participants without an event were censored at the last known alive day, study Day 368, or the last date during the double-blind period.

A positive ATA result was defined as one in which the presence of detectable ATAs could be confirmed by competitive binding with lebrikizumab. Percentage of participants with positive results for ATA at Baseline and at post-baseline time points were reported. Only participants who received lebrikizumab were included in the analysis.
