NCT07557225

Brief Summary

The goal of this clinical trial is to evaluate the diagnostic value of CAIX protein specific probe 18F-T2 in PET/CT imaging in participants with solid tumors. It will also assess the safety, tolerability and radiation dosimetry of 18F-T2.

Outcome Measures

Primary Outcomes (2)

  • The Diagnostic Sensitivity and Specificity of 18F-T2 PET/CT in the Evaluation of CAIX Positive Solid Tumors

    The diagnostic performance of 18F-T2 PET/CT and 18F-FDG PET/CT for staging will be evaluated and compared, using histopathological findings as the gold standard or, if not available, follow-up clinical and conventional imaging examinations (ultrasound, CT, or MRI) for at least 3 months as the reference standard.

    From study completion to 1 month after completion

  • Incidence of Adverse Events [Safety and Tolerability]

    Safety of administration of 18F-T2, according to Common Terminology Criteria for Adverse Events (CTCAE v6.0).

    24 hours after the injection of 18F-T2

Secondary Outcomes (4)

  • Maximum Standardized Uptake Value [SUVmax] of Primary and Metastatic Lesions on 18F-T2 PET/CT vs. 18F-FDG PET/CT

    From study completion to 1 month after completion

  • Mean Standardized Uptake Value [SUVmean] of Primary and Metastatic Lesions on 18F-T2 PET/CT vs. 18F-FDG PET/CT

    From study completion to 1 month after completion

  • Correlation between T2 Uptake and CAIX Pathological Expression

    From study completion to 1 month after completion

  • Dosimetry of 18F-T2

    From study completion to 1 month after completion

Study Arms (1)

18F-T2 PET/CT

EXPERIMENTAL

Participants with tumors likely to express high levels of CAIX will receive an intravenous injection of 18F-T2 followed by PET/CT imaging. The participants will also receive a whole-body 18F-FDG PET/CT scan within a one-week period.

Diagnostic Test: 18F-T2 PET/CT

Interventions

18F-T2 PET/CTDIAGNOSTIC_TEST

18F-T2 is injected intravenously with a dose of 0.05-0.10 mCi/kg. The CT and PET imaging session will begin approximately 60 minutes after 18F-T2 administration.
