Current Primary Outcome Measures  ICMJE
 (submitted: August 22, 2018)
Annualized Rate of Decrease in Percent Predicted Forced Vital Capacity (FVC) Over 52 Weeks [ Time Frame: 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.

    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.
  • Percentage of Participants With Event of Greater Than or Equal to (>/=) 10% Absolute Decline in Percent Predicted FVC or Death From Any Cause [ Time Frame: 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. 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 [ Time Frame: 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. Predicted FVC is based on sex, age, and height of a person. Percent predicted FVC (in %) = [(observed FVC)/(predicted FVC)]*100. 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.

    Annualized rates of decrease (slope throughout time from baseline to Week 52) in DLco was assessed and reported. DLco (in milliliters per minute/millimeters of mercury [mL/min/mmHg]) is a measure of the gas transfer.
  • Percentage of Participants With Event of Death, All Cause Hospitalization, or a Decrease From Baseline of >/=10% in FVC [ Time Frame: 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.
  • Progression-Free Survival (PFS) [ Time Frame: 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.
  • Annualized Rate of Decrease in FVC Over 52 Weeks [ Time Frame: 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.
  • Annualized Rate of Decrease in A Tool to Assess Quality of Life in IPF (ATAQ-IPF) Questionnaire Total Score Over 52 Weeks [ Time Frame: 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.
  • Percentage of Participants With an Event of St. George's Respiratory Questionnaire (SGRQ) Total Score Worsening or Death From Any Cause [ Time Frame: 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 to First Event of >/=15% Absolute Decrease in Percentage of Predicted DLco or Death From Any Cause [ Time Frame: Baseline up to the event of >/=15% absolute decrease in percentage of predicted DLco or death from any cause (up to Week 122) ]

    ATA to lebrikizumab was tested using a validated immunoassay. 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.
