|Idiopathic Pulmonary Fibrosis||Drug: Pamrevlumab Drug: Placebo||Phase 3|
This is a Phase 3, randomized, double-blind, placebo-controlled, multi-center trial to evaluate the efficacy and safety of pamrevlumab in subjects with idiopathic pulmonary fibrosis (IPF).
Subjects who are not being treated with approved IPF therapies (i.e., nintedanib or pirfenidone) may be eligible for screening. Examples of reasons subjects may not be treated with approved IPF therapies include but are not limited to:
- Intolerant or not responsive to approved IPF therapies
- Ineligible to receive these therapies
- Subject voluntarily declines to receive approved IPF therapies after being fully informed of the potential benefits/risks
NOTE: No subject should discontinue an approved IPF therapy for the purpose of enrolling in this study.
Approximately 340 eligible subjects will be randomized at a 1:1 ratio to Arm A or Arm B, respectively:
Arm A: pamrevlumab, 30 mg/kg IV, Day 1 and every 3 weeks thereafter
Arm B: Matching placebo IV, Day 1 and every 3 weeks thereafter
The study consists of the following study periods:
Main (double blind, placebo-controlled) phase:
- Screening period: Up to 6 weeks
- Treatment period: 48 weeks
Optional, open label extension (OLE) phase of pamrevlumab:
o Access to pamrevlumab will be available until the last subject completes 48 weeks of treatment in the OLE phase, or pamrevlumab is commercially available for the indication of IPF, or the Sponsor decides to end the OLE phase, whichever occurs first.
Follow-up period/final safety assessments:
- 28 days after last dose
- 60 days after last dose: follow-up phone call, for a final safety assessment
During the treatment period, co-administration of an approved IPF therapy (i.e., pirfenidone or nintedanib) is acceptable if clinically indicated in the Investigator's opinion, provided that the Investigator assesses the potential risks/benefits of combining approved IPF therapies with blinded study treatment.
Subjects who discontinue study treatment for any reason should be encouraged to remain in the study and be followed for all study visits and assessments.
Subjects who complete the study will be eligible for an open-label, extension with pamrevlumab.

Pamrevlumab: 30 mg/kg by intravenous infusion every 3 weeks for a total of 17 infusions over 48 weeks
Other Name: FG-3019
Placebo: 30 mg/kg by intravenous infusion every 3 weeks for a total of 17 infusions over 48 weeks
- Change in FVC (L) [ Time Frame: Baseline to Week 48 ]
- Time to disease progression defined as absolute FVCpp decline of ≥10% or death, whichever occurs first. [ Time Frame: Baseline to Week 48 ]
- Change in FVCpp (absolute and relative) [ Time Frame: Baseline to Week 48 ]
- Time to composite of clinical outcomes: respiratory hospitalization or death or absolute FVCpp decline ≥10%, whichever occurs first [ Time Frame: Baseline to Week 48 ]
- Time to first respiratory hospitalizations during study [ Time Frame: Baseline to Week 48 ]
- Change in Quantitative Lung Fibrosis (QLF) volume [ Time Frame: Baseline to Week 48 ]
- Change in St. George's Respiratory Questionnaire (SGRQ) [ Time Frame: Baseline to Week 48 ]The SGRQ is a 50-item questionnaire developed to measure health status (quality of life). Scores are calculated for three domains: Symptoms, Activity and Impacts. The total score (summed weights) can range from 0 to 100 with a lower score denoting a better health status.
- Change in University of California San Diego - Shortness of Breath Questionnaire (UCSD-SOBQ) [ Time Frame: Baseline to Week 48 ]The UCSD SOBQ is a 24-item questionnaire developed to measure breathlessness associated with activities of daily living, on a scale between zero and five where 0 is not at all breathless and 5 is maximally breathless or too breathless to do the activity. The responses to all items are summed up to provide the overall score that can range from 0 (best outcome) to 120 (worst outcome).
- Change in Leicester Cough Questionnaire (LCQ) [ Time Frame: Baseline to Week 48 ]The LCQ is a self-reporting quality of life measure of chronic cough. It consists of 19 items with a 7 point likert response scale (range from 1 to 7). Each item is developed to assess symptoms during cough and impact of cough on three main domains: physical, psychological and social. Scores are calculated as a mean of each domain and the total score is calculated by adding every domain score.
- Time to all-cause mortality during study [ Time Frame: Baseline to Week 48 ]
- Time to first acute IPF exacerbations during study [ Time Frame: Baseline to Week 48 ]
