Clinical Study of 18F-FAPI-RGD in Interstitial Lung Disease Associated With Connective Tissue Disease

Study Purpose

The goal of this observational study is to examine clinical utility of 18F-FAPI-RGD PET/CT imaging in evaluating connective tissue disease-associated interstitial lung disease. Participants will undergo clinical evaluation and 18F-FAPI-RGD PET/CT examination.

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.	Observational
Eligible Ages	18 Years and Over
Gender	All

- Patients who have been diagnosed with, or are clinically highly suspected of ILD.

- Patients who have been diagnosed with, or are clinically highly suspected of CTD-ILD.

Exclusion Criteria:

- Pregnant or breastfeeding.

- Patients with tumor, other respiratory diseases, and lung surgery.

- Abnormal cardiopulmonary function or mental state, unable tolerate PET/CT

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.	NCT06143540
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.

Additional Details

Interstitial lung disease is an overarching term for a wide range of disorders characterized by inflammation and/ or fibrosis in the lungs. Interstitial lung disease associated connective tissue diseases(CTD-ILD) is one of the most common types.The goal of this study is to explore the feasibility of using 18F-FAPI-RGD, a dual-targeting heterodimeric PET tracer that recognizes both fibroblast activation protein (FAP) and integrin αvβ3 for detecting connective tissue disease associated interstitial lung disease (CTD-ILD), and analyze the relationship between 18F- FAPI-RGD PET/CT images and related parameters of lung function, clinical laboratory indicators and HRCT scores.
