Conditions

Breast Cancer, Cervical Cancer, Cholangiocarcinoma, Clear Cell Renal Cell Cancer (ccRCC), Colorectal Cancer, Endometrial Cancer, Head and Neck Cancer, Hepatocellular Carcinoma (HCC), Non Small Cell Lung Cancer, Ovarian Cancer, Pancreatic Cancer, Small Cell Lung Cancer, Urothelial Carcinoma (UC), Von Hippel Lindau Disease

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.

Interventions

DIAGNOSTIC_TEST18F-T2 PET/CT

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.

Inclusion criteria

All participants must meet the following criteria: 1. Written and voluntarily given Informed Consent. 2. Male or female ≥18 years of age at time of consent. 3. Have the capacity to understand the study and be willing and able to comply with all protocol requirements. 4. Participants with histologically confirmed or suspected tumors of the following types, but not limited to: Clear Cell Renal Cell Cancer; Urothelial Carcinoma; Colorectal Cancer; Cervical Cancer; Ovarian Cancer; Head and Neck Cancer; Hepatocellular Carcinoma; Cholangiocarcinoma; Non Small Cell Lung Cancer; Small Cell Lung Cancer; Breast Cancer; Pancreatic Cancer; Endometrial Cancer; Von Hippel Lindau Disease.

Exclusion criteria

Participants will be excluded from participation in the study if one or more of the following criteria are met: 1. Have any serious non-malignant disease (e.g., psychiatric, infectious, autoimmune or metabolic) that may interfere with the objectives of the study or with the safety or compliance of the participant, as judged by the Investigator. 2. Have a mental impairment that may compromise the ability to give Informed Consent and comply with the requirements of the study. 3. Be a female who is pregnant or breastfeeding.

Design outcomes

Primary

MeasureTime frameDescription
The Diagnostic Sensitivity and Specificity of 18F-T2 PET/CT in the Evaluation of CAIX Positive Solid TumorsFrom study completion to 1 month after completionThe 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.
Incidence of Adverse Events [Safety and Tolerability]24 hours after the injection of 18F-T2Safety of administration of 18F-T2, according to Common Terminology Criteria for Adverse Events (CTCAE v6.0).

Secondary

MeasureTime frameDescription
Maximum Standardized Uptake Value [SUVmax] of Primary and Metastatic Lesions on 18F-T2 PET/CT vs. 18F-FDG PET/CTFrom study completion to 1 month after completionComparison of maximum standardized uptake value (SUVmax) of primary and metastatic lesions between 18F-T2 PET/CT and 18F-FDG PET/CT.
Mean Standardized Uptake Value [SUVmean] of Primary and Metastatic Lesions on 18F-T2 PET/CT vs. 18F-FDG PET/CTFrom study completion to 1 month after completionComparison of mean standardized uptake value (SUVmean) of primary and metastatic lesions between 18F-T2 PET/CT and 18F-FDG PET/CT.
Correlation between T2 Uptake and CAIX Pathological ExpressionFrom study completion to 1 month after completionEvaluation of the correlation between uptake parameters derived from 18F-T2 PET/CT and CAIX expression level measured by immunohistochemistry (IHC) in tumor tissue samples.
Dosimetry of 18F-T2From study completion to 1 month after completionResearch on the dose distribution of 18F-T2 in healthy volunteers and cancer patients by 1-hour dynamic PET/CT acquisition and analyze by the dosimetry software.
