Evaluation of Efficacy and Safety of Pamrevlumab in Patients With Idiopathic Pulmonary Fibrosis

Study Purpose

This is a Phase 3 trial to evaluate the efficacy and safety of 30 mg/kg intravenous (IV) infusions of pamrevlumab administered every 3 weeks as compared to placebo in subjects with Idiopathic Pulmonary Fibrosis

Recruitment Criteria

Accepts Healthy Volunteers Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms	No
Study Type An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes. An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes. Searching Both is inclusive of interventional and observational studies.	Interventional
Eligible Ages	40 Years - 85 Years
Gender	All

More Inclusion & Exclusion Criteria

Key

Inclusion Criteria:

1. Diagnosis of IPF as defined by ATS/ERS/JRS/ALAT guidelines (Raghu 2018) within the past 7 years prior to study participation. 2. HRCT scan at Screening, with ≥10% to <50% parenchymal fibrosis (reticulation) and <25% honeycombing. 3. FVCpp value >45% and <95% 4. Diffusing capacity of the lungs for carbon monoxide (DLCO) percent predicted ≥25% and ≤90% at screening (determined locally). 5. Not currently receiving treatment for IPF with an approved therapy (i.e., pirfenidone or nintedanib) for any reason, including prior intolerance to an approved IPF therapy. Key

Exclusion Criteria:

1. Previous exposure to pamrevlumab. 2. Evidence of significant obstructive lung disease. 3. Female subjects who are pregnant or nursing. 4. Smoking within 3 months of Screening and/or unwilling to avoid smoking throughout the study. 5. Interstitial lung disease other than IPF. 6. Sustained improvement in the severity of IPF. 7. Other types of respiratory diseases including diseases of the airways, lung parenchyma, pleural space, mediastinum, diaphragm, or chest wall. 8. Certain medical conditions, including recent (e.g. MI/stroke, or severe chronic heart failure or pulmonary hypertension, or cancers. 9. Acute IPF exacerbation during Screening or Randomization. 10. Recent use of any investigational drugs or unapproved therapies, or approved or participation in any clinical trial. 11. History of allergic or anaphylactic reaction to human, humanized, chimeric or murine monoclonal antibodies.

Trial Details

Trial ID: This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.	NCT03955146
Phase Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans. Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data. Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs. Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.	Phase 3

Additional Details

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.
