An observational study in Tuberculosis, Pulmonary, sponsored by Children's Hospital Medical Center, Cincinnati. Recruiting at 1 site in United States. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2026-03-31.
Sponsored by Children's Hospital Medical Center, Cincinnati · Observational
The investigators will assess the hypothesis is that 18F-Fibroblast Activation Protein Inhibitor (18F-FAPI-74) Positron emission tomography (PET) could be used as a noninvasive biomarker to assess post-tuberculosis (post-TB) lung disease and fibrosis in TB patients.
Microbiologically confirmed patients with active tuberculosis will be invited to participate in the study. A whole-body PET scan will be performed after 18F-FAPI-74 intravenous injection and correlation will be made with sites of TB lesions noted on CT. It is anticipated that 18F-FAPI-74 PET will be able to detect fibrosis (with high sensitivity) in the TB lesions.

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.
Judged by the study doctor to matter for your health or for the study. It is a doctor’s decision, so ask the study team if you are unsure whether something counts.
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.

A single intravenous dose of 18F-FAPI-74 followed by PET/CT scan pre- and post-TB treatment.
Combination Product: 18F-FAPI-74
7 millicurie (mCi) of 18F-FAPI-74 in adult tuberculosis patient followed by a PET/CT scan, performed during the first 6 weeks of treatment and/or a second dose of 7 millicurie (mCi) of 18F-FAPI-74 in adult tuberculosis patient followed by a PET/CT scan within 6 weeks after tuberculosis treatment completion.
Uptake of 18F-FAPI-74 derived by the standardized uptake value ratio (SUVr)
Characterization of lesional fibrosis using 18F-FAPI-74 PET/CT in tuberculosis patients. Whole-body PET/CT scans will be obtained after intravenous injection of 18F-FAPI-74. Uptake will be measured at sites of TB lesions and unaffected areas.
Time frame: Up to 1 hour
