Clinical Application of FAP-Targeted Radionuclide Imaging in the Diagnosis and Staging of Malignant Solid Tumors

July 12, 2026 updated by: Union Hospital, Tongji Medical College, Huazhong University of Science and Technology
This study is a single-center, open-label first-in-human clinical study. Patients with clinically suspected or confirmed malignant solid tumors will undergo [68Ga]Ga-FAP PET imaging or [177Lu]Lu-FAP SPECT imaging as well as [18F]FDG PET imaging to determine the presence or absence of lesions, and to assess lesion location, characteristics, and metastasis. Histopathological diagnosis or follow-up results will serve as the reference standard. The diagnostic efficacy of [68Ga]Ga-FAP PET imaging or [177Lu]Lu-FAP SPECT imaging for malignant tumors will be evaluated. Additionally, the study will analyze the biodistribution and dosimetry of [177Lu]Lu-FAP following a single administration, explore the correlation between tumor uptake values on imaging and immunohistochemical FAP expression levels, and evaluate the safety and tolerability of a single low-dose intravenous injection of [68Ga]Ga-FAP or [177Lu]Lu-FAP for diagnostic imaging.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

  7. Patients with active infection (e.g., acute bacterial infection, tuberculosis, active hepatitis B/C, active syphilis, etc.). Active hepatitis B is defined as: positive HBsAg or HBcAb, or results outside the normal reference range, accompanied by hepatitis B virus DNA titer > 2500 copies/mL or > 500 IU/mL. Active hepatitis C is defined as: positive hepatitis C antibody, or results outside the normal reference range, and positive HCV-RNA.
