Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

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.
