Imaging of Pathologic Fibrosis Using 68Ga-FAP-2286

Study Purpose

This is a single arm prospective pilot trial that evaluates the ability of a novel imaging agent (68Ga-FAP-2286) to identify pathologic fibrosis in the setting of hepatic, cardiac and pulmonary fibrosis. FAP-2286 is a peptide that potently and selectively binds to Fibroblast Activation Protein (FAP). FAP is a transmembrane protein expressed on fibroblasts and has been shown to have higher expression in idiopathic pulmonary fibrosis (IPF), cirrhosis, and cardiac 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	18 Years and Over
Gender	All

More Inclusion & Exclusion Criteria

Inclusion Criteria:

1. Age >= 18 years. 2. Confirmed pathologic fibrosis in one of the following cohorts. 1. Cohort 1: Hepatic fibrosis, based on cirrhosis on imaging or hepatic fibrosis on liver biopsy. 2. Cohort 2: Pulmonary fibrosis, based on CT findings or biopsy of lung parenchyma. 3. Cohort 3: High likelihood of cardiac fibrosis as indicated by known cardiac sarcoidosis or amyloidosis (shown on MRI or Fluorodeoxyglucose (FDG) PET), recent myocardial infarction within the last 30 days (as shown by an elevated troponin), known cardiotoxicity (decreased ejection fraction on systemic therapy), or other known inflammatory or infiltrative disease. 3. Ability to understand a written informed consent document, and the willingness to sign it.

Exclusion Criteria:

1. Unlikely to comply with protocol procedures, restrictions and requirements and judged by the Investigator to be unsuitable for participation. 2. Known pregnancy.

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.	NCT05180162
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 1

Additional Details

PRIMARY OBJECTIVES:

I. All cohorts: Safety of 68Ga-FAP-2286.

II. Cohort 1: Measured uptake of radiotracer (SUVpeak) in regions of known liver fibrosis.

III. Cohort 2: Measured uptake of radiotracer (SUVpeak) in regions of known pulmonary fibrosis.

IV. Cohort 3: Measured uptake of radiotracer (SUVpeak) in regions of myocardial fibrosis.

EXPLORATORY OBJECTIVES:

I. Correlation of 68Ga-FAP-2286 uptake with FAP expression determined by immunohistochemistry.

II. Compare 68Ga-FAP-2286 scan results to archival Computerized tomography (CT), magnetic resonance imaging (MRI), or Positron Emission Tomography (PET) images.

Patients will receive a single administration of 68Ga-FAP-2286 prior to PET imaging and will be followed for up to two hours after the injection of 68Ga-FAP-2286 for evaluation of adverse events.
