Study Details

Study Description

Brief Summary

To evaluate the potential usefulness of 18F-AlF-FAPi-04 PET/CT for the diagnosis of primary and metastatic lesions in solid cancer.

Condition or Disease Intervention/Treatment Phase
  • Drug: Radiation: 18F-AlF-FAPi-04
  • Drug: Radiation: 18F-FDG
Early Phase 1

Detailed Description

This is a prospective, single-center, two arms, open label, non-randomized study to evaluate the ability of 18F-AlF-FAPi-04 to detect FAP expressing cells in patients with solid tumor, evaluate its biological distribution characteristics, impact on clinical treatment plans, and evaluate imaging differences between different probes. Taking histopathology and imaging follow-up as gold standard, the sensitivity, specificity, and accuracy of 18F-AlF-FAPi-04 PET/CT will be calculated.

Arms and Interventions

Arm Intervention/Treatment
Experimental: Group A

Patients who are surgically resectable or borderline surgically resectable plan to undergo primary lesion resection and peripheral lymph node dissection, and suspect the presence of peripheral lymph nodes or distant metastasis; Pathological results of postoperative primary lesion and lymph node dissection can be obtained

Drug: Radiation: 18F-AlF-FAPi-04
Subjects who meet all the inclusion criteria will receive intravenous administration of 18F-AlF-FAPi-04 with a dosage range of 0.1-0.2 mCi/Kg. After administration, PET/CT scans will be performed at three time points: 1h, 2h, and 4h post dose. The subjects will also receive administration of 18F-FDG and undergo PET/CT scans for self-control analysis.

Drug: Radiation: 18F-FDG
Subjects who meet all the inclusion criteria will receive intravenous administration of 18F-AlF-FAPi-04 with a dosage range of 0.1-0.2 mCi/Kg. After administration, PET/CT scans will be performed at three time points: 1h, 2h, and 4h post dose. The subjects will also receive administration of 18F-FDG and undergo PET/CT scans for self-control analysis.

Experimental: Group B

For patients diagnosed or suspected of postoperative recurrence or late metastasis through routine imaging examination, there is at least one measurable lesion (with a short diameter of ≥ 1.5cm for lymph node lesions and ≥ 1cm for non lymph node lesions); Patients who can undergo imaging follow-up for 3-6 months or undergo pathological biopsy and puncture.

Drug: Radiation: 18F-AlF-FAPi-04
Subjects who meet all the inclusion criteria will receive intravenous administration of 18F-AlF-FAPi-04 with a dosage range of 0.1-0.2 mCi/Kg. After administration, PET/CT scans will be performed at three time points: 1h, 2h, and 4h post dose. The subjects will also receive administration of 18F-FDG and undergo PET/CT scans for self-control analysis.

Drug: Radiation: 18F-FDG
Subjects who meet all the inclusion criteria will receive intravenous administration of 18F-AlF-FAPi-04 with a dosage range of 0.1-0.2 mCi/Kg. After administration, PET/CT scans will be performed at three time points: 1h, 2h, and 4h post dose. The subjects will also receive administration of 18F-FDG and undergo PET/CT scans for self-control analysis.

Outcome Measures

Primary Outcome Measures

  1. Group A: Sensitivity and Specificity of 18F-AlF-FAPi-04 [6 months after last dose administration]

    Performance [sensitivity, specificity, accuracy] of 18F-AlF-FAPi-04 PET imaging to detect FAP-expressing cells, using surgical histopathological results as truth standard

  2. Group B: Sensitivity and Specificity of 18F-AlF-FAPi-04 [6 months after last dose administration]

    Performance [sensitivity, specificity, accuracy] of 18F-AlF-FAPi-04 PET imaging to detect FAP-expressing cells, using imaging follow-up or histopathological puncture results as truth standard

Secondary Outcome Measures

  1. Biodistribution of 18F-AlF-FAPi-04 [120 minutes after tracer injection]

    The biodistribution of 18F-AlF-FAPi-04 in normal and cancer tissues of patients with various malignancies will be measured by average and maximum standardized uptake value (SUVmean and SUVmax)
