A Phase 2 interventional study of FAPI tracer in Systemic Sclerosis (SSc), Scleroderma and Interstitial Lung Disease With Systemic Sclerosis, sponsored by University of California, Los Angeles. Not yet recruiting at 1 site in United States. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2026-11-09.
Sponsored by University of California, Los Angeles · Phase 2, Interventional, and Diagnostic
This is a phase II open-label efficacy and safety study to evaluate standard of care treatment response measured by PET imaging radiotracer 68Ga-FAPI-46 in 120 subjects with SSc-ILD.
610 studies on the registry are indexed under Scleroderma, Systemic; 218 are open to participants now.
This study's planned enrollment of 120 is above the median of 37 across 446 interventional studies indexed under Scleroderma, Systemic.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).
Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.
Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.
Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.
Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.
Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.
A drug or device being studied in a clinical trial.
It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.

Drug: FAPI tracer
68Ga-FAPI-46 will be used for the PET/CT for SSc ILD patients
Prediction progressive pulmonary fibrosis (PPF) by evaluation of the change in uptake of radiotracer 68Ga-FAPI-46
This endpoint will evaluate whether the change in uptake of radiotracer 68Ga-FAPI-46 from baseline to 6 months of treatment predicts progressive pulmonary fibrosis (PPF) at 1 year according to American Thoracic Society guidelines.
Time frame: 1 year
Prediction progressive pulmonary fibrosis (PPF) by evaluation of the change in the levels of specific blood-based biomarkers
This endpoint will evaluate whether the change in circulating biomarkers levels at 6 months predicts PPF at 1 year using the same definition above.
Time frame: 1 year
