Fibrotic Disease Activity in Cardiopulmonary Disorders Using 18F-Fibroblast Activation Protein Inhibitor (18F-FAPI-74) PET/CT Imaging
A Phase 3 study testing [18F]FAPI-74 and 18F-FAPI-74 PET/CT Imaging in people with Allogeneic Stem Cell Transplantation and Lung Allograft Transplantation, run by National Heart, Lung, and Blood Institute (NHLBI) at 1 site in United States.
Trial summary
Background: Injury or diseases of the heart and lung can sometimes cause scar tissue (fibrosis) to build up in those organs. Current imaging scans can see this scar tissue once it has formed, but researchers want to find a way to detect the fibrosis in its earliest stages, while there might still be time to prevent… Read more about this study

About this study
Official title: Evaluation of Fibrotic Disease Activity in Cardiopulmonary Disorders Using 18F-Fibroblast Activation Protein Inhibitor (18F-FAPI-74 PET/CT Imaging)
Background:
Injury or diseases of the heart and lung can sometimes cause scar tissue (fibrosis) to build up in those organs. Current imaging scans can see this scar tissue once it has formed, but researchers want to find a way to detect the fibrosis in its earliest stages, while there might still be time to prevent serious damage. A new tracer (a radioactive substance injected during imaging scans) may be able to help.

Objective:
To test a new tracer (18F-FAPI-74) during imaging scans in people with heart or lung disease.
Eligibility:
People aged 18 years and older with lung or heart disease that may cause scarring in those organs.
Design:
Participants will have 6 clinic visits over 2 years.
Participants will be screened: They will have blood tests and tests of their heart and lung function. Those with heart disease will have a magnetic resonance imaging (MRI) scan of the heart.
The study tracer will be used with positron emission tomography (PET)/computed tomography (CT) scans. The study tracer will be injected into a vein in the arm. Participants will lie on a padded bed that slides through a donut-shaped machine.
Participants will have scans with the study tracer 2 times, 8 to 12 months apart. They will also have standard CT scans and blood tests during these visits. They will also have blood tests at 3 and 6 months between these visits.
Participants will have a follow-up visit after 18 to 24 months. The study scans, MRI and standard CT scans, and lung function tests may be repeated....

Study Description:
Fibroblast activation protein-targeted PET detects activated fibroblasts in a range of inflammatory and fibrosing cardiovascular and pulmonary disorders. It is a sensitive and quantifiable intervention to diagnose and monitor the natural history of cardiopulmonary disorders and/or the effects of antifibrotic interventions.
Objectives:
Primary objective:
To compare 18F-FAPI-74 PET/CT to standard of care (SOC) imaging (18F-FDG-PET/CT, non-contrast chest CT, and cardiac MRI for heart cohort) to detect fibrosis.
Secondary objective:
To compare the ability of 18F-FAPI-74 PET/CT imaging to assess the natural history or treatment responses with standard of care imaging in cardiopulmonary diseases associated with fibrosis.
Exploratory objectives:
To use high density proteomic, transcriptomic, and metagenomic analysis of specimens from lung and/or blood to define associated mechanisms and biomarkers of active fibrosis with the visualization and quantification of FAP expression. To assess the usefulness of cardiopulmonary imaging with low-field heart lung MRI for characterization of the lung microarchitecture, microvascular perfusion, regional ventilation, and late gadolinium enhancement.
Endpoints:
Primary:
Compare 18F-FAPI-74 PET/CT to standard of care (SOC) imaging with 18F-FDG-PET/CT (with the rate of concordance defined as a quantitative measure of the abnormal lung parenchyma detected in both the FAPI and FDG PET scans ranging from 0 to 100%) and cardiac MRI for heart cohort for the development of pulmonary or cardiovascular fibrosis at baseline These findings will be evaluated separately in six different at-risk cohorts (allogeneic stem cell transplant, lung allograft transplant, interstitial lung disease, acute lung injury, pulmonary arterial hypertension, and cardiovascular disease).
Secondary:
Compare the ability of 18F-FAPI-74 PET/CT imaging to assess the progression of fibrosis or treatment response compared to SOC imaging. The magnitude of change in 18F-FAPI-74 PET/CT uptake (SUVmax and mean/median) between scans one and two will be compared. Comparisons of the quantitative chest CT abnormalities will be compared to both 18F-FAPI-74 PET/CT and 18F-FDGPET/CT scans. These findings will be evaluated separately in six different at-risk cohorts (allogeneic stem cell transplant, lung allograft transplant, interstitial lung disease, acute lung injury, pulmonary arterial hypertension, and cardiovascular disease). Comparison of 18F-FAPI-74 PET/CT to standard of care (SOC) imaging at up to 12 months after the initial scan at baseline and change from the baseline.
Exploratory:
To use high density proteomic, transcriptomic, and metagenomic analysis of specimens from lung and/or blood to define associated biomarkers and mechanisms of active fibrosis with the visualization and quantitation of FAP expression. To assess the usefulness of
cardiopulmonary imaging with low-field heart lung MRI for characterization of the lung microarchitecture, microvascular perfusion, regional ventilation, and late gadolinium enhancement.

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing [18F]FAPI-74 and 18F-FAPI-74 PET/CT Imaging in people with Allogeneic Stem Cell Transplantation and Lung Allograft Transplantation, run by National Heart, Lung, and Blood Institute (NHLBI) at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 10 inclusion and 7 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: looking for participants now, as of the sponsor's last update on 26 Oct 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Rosemary McConnell, R.N. ((301) 827-9716, rosemary.mcconnell@nih.gov), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
To compare 18F-FAPI-74 PET/CT to standard of care imaging (non-contrast chest CT and 18F-FDG-PET/CT, cardiac MRI for heart cohort) to detect fibrosis. (time frame: Initial scan, Baseline, 8-12 months). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 26 Oct 2026.
