Characterizing Spondyloarthritis With 68Ga-FAPI PET/CT
Study Overview

Intervention / Treatment
Detailed Description
Spondyloarthritis (SpA) is a chronic inflammatory rheumatic disease characterized by inflammatory back pain, enthesitis, dactylitis, and the formation of syndesmophytes, all of which significantly affect a patient's healthy functioning and general quality of life. Prevalence of underlying malignancy is high in patients with SpA. Radiographic sacroiliitis became a crucial finding in the diagnosis and classification of patients.
68Ga-FAPI has been developed as tracers specific for fibroblast-activation protein (FAP), which is overexpressed in activated fibroblasts in various type of cancers and autoimmune diseases, such as rheumatoid arthritis, IgG4-related diseases and interstitial lung diseases.
Recently the investigators have published articles of the application of 68Ga-FAPI in IgG4-related disease and rheumatoid arthritis, which showed it was more sensitive than FDG in detecting a certain type of inflammation. Increased 68Ga-FAPI Uptake in ankylosing spondylitis in a patient with rectal cancer has also been reported in a case report, indicating the potential utility of FAP-targeted PET/CT imaging for diagnosis and disease assessment in spondyloarthritis.
Thus, this prospective study is going to investigate utility of 68Ga-FAPI PET/CT in diagnosis of spondyloarthritis as well as inflammation assessment in joints including the sacroiliac (SI) joints, spine and peripheral joints. Also, this study aims to investigate potential utility of 68Ga-FAPI PET/CT in predicting treatment response and disease prognosis such as formation of syndesmophytes and erosive changes.

Experimental: Inject 68Ga-FAPI and then perform PET/CT scan.
Inject 68Ga-FAPI and then perform PET/CT scan
|
Intravenous injection of one dosage of 111-185 MBq (3-5 mCi) 68Ga-FAPI.
Tracer doses of 68Ga-FAPI will be used to image SpA lesions in SI joints, spine, musculoskeletal and the extra-articular involvement by PET/CT.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
To define the distribution pattern of 68Ga-FAPI in SpA patients.
Time Frame: 60 minutes following injection
|
To quantify 68Ga-FAPI tracer biodistribution in characteristic inflammatory tissue including SI joints, spine, and the peripheral joints versus conventional x ray examination or magnetic resonance imaging (MRI) techniques in adult active SpA.
68Ga-FAPI PET tracer biodistribution will be assessed by semi-quantitative analysis (unit/metrics = standardized uptake values (SUV)).
|
60 minutes following injection
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Correlation between uptake of 68GA-FAPI and other parameters associated with disease activity.
Time Frame: 30 days
|
Correlation between uptake of 68GA-FAPI and parameters associated with disease activity including Ankylosing Spondylitis Disease Activity Score (ASDAS), Bath ankylosing spondylitis disease activity index (BSADAI), Bath ankylosing spondylitis functional index (BASFI),and Maastricht Ankylosing Spondylitis Enthesitis Score(MASES).
The Standardized uptake value (SUV) of 68Ga-FAPI was calculated and analyzing the correlation between pathological results and parameters associated with disease activity.
|
30 days
|
Correlation between uptake of 68GA-FAPI change and disease activity change
Time Frame: Up to 2 years
|
Correlation between change in standardized uptake value (SUV) of 68Ga-FAPI at inflammatory site with change in Ankylosing Spondylitis Disease Activity Score (ASDAS), Bath ankylosing spondylitis disease activity index (BSADAI), Bath ankylosing spondylitis functional index (BASFI),and Maastricht Ankylosing Spondylitis Enthesitis Score(MASES) at different disease stage.
|
Up to 2 years
|
Correlation between uptake of 68GA-FAPI and therapy response
Time Frame: Up to 2 years
|
Percentage of participants achieving ankylosing spondylitis disease activity score inactive disease [ASDAS ID (<1.3)] after 1 year standardized treatment in participants with high standardized uptake value (SUV) of 68Ga-FAPI and low standardized uptake value (SUV) of 68Ga-FAPI at baseline.
