- Progression Free Survival [ Time Frame: Up to 148 weeks ]Progression free survival (PFS) was defined as the categorical decrease in forced vital capacity (FVC) % predicted (≥ 10% relative decrease in FVC and ≥ 5% absolute decrease in FVC from baseline) with confirmation at a consecutive visit at least 2 weeks later using the same criteria.
- PFS Among the Participants With sLOXL2 ≥ 50th Percentile [ Time Frame: Up to 148 weeks ]
- PFS Among the Participants With sLOXL2 ≥ 75th Percentile [ Time Frame: Up to 148 weeks ]
- Overall Survival (OS) [ Time Frame: Up to 151 weeks ]Overall survival was defined as the time from randomization date to death that occurred prior to the last dose date plus 30 days.
- Overall Survival Among the Participants With sLOXL2 ≥ 50th Percentile [ Time Frame: Up to 151 weeks ]
- Overall Survival Among the Participants With sLOXL2 ≥ 75th Percentile [ Time Frame: Up to 151 weeks ]
- Relative Change From Baseline in FVC % Predicted [ Time Frame: Weeks 54, 106, and 130 ]
- FVC was defined as the volume of air (liters) that can forcibly be blown out after taking a full breath. FVC % predicted was defined as FVC % of the participant divided by the average FVC % in the population for any person of similar age, sex, and body composition.
- Adjusted means were from mixed model repeated measures (MMRM) model with baseline FVC % predicted, sLOXL2 level, concomitant pirfenidone/nintedanib use (never vs. ever), treatment, visit, and treatment-by-visit interaction terms, including all data up to Week 130
- The relative change was calculated as 100% * ( value at later time point minus value at baseline ) / value at baseline, with lower values indicating a decrease and higher values indicating an increase.
- Definite Acute Exacerbations of IPF Among Adjudicated Respiratory Hospitalizations [ Time Frame: Up to 148 weeks ]
- Number of Adjudicated Respiratory Hospitalizations (ARP) Among Total Hospitalizations [ Time Frame: Up to 148 weeks ]
- Number of Participants Experiencing Adjudicated Respiratory Deaths Among Those With Adjudicated Death [ Time Frame: Up to 148 weeks ]
- Absolute Change From Baseline in 6 Minute Walk Distance (6MWD) [ Time Frame: Weeks 58, 106, and 130 ]
- Adjusted means were from MMRM model with baseline 6MWD, FVC % predicted, sLOXL2 level, concomitant pirfenidone/nintedanib use (never vs. ever), treatment, visit, and treatment-by-visit interaction terms, including all data up to Week 130.
- The absolute change was calculated as value at later time point minus value at baseline, with lower values indicating a decrease and higher values indicating an increase.
- Absolute Change From Baseline in St. George's Respiratory Questionnaire (SGRQ) Score [ Time Frame: Week 58, 106, and 130 ]
- The SGRQ is a disease-specific questionnaire designed to measure impact on overall health, daily life, and perceived well-being in patients with obstructive airways disease. Patients respond to questions about symptoms (frequency & severity) and impact components (social functioning and psychological disturbances resulting from airways disease). Scores range from 0 to 100, with higher scores indicating more limitations.
- The absolute change was calculated as value at later time point minus value at baseline, with lower values indicating a decrease and higher values indicating an increase.
