Evaluation of an EpCAM-Targeted Radiotracer in Epithelial Tumors

Recruiting now · Not applicable

Conditions studied: Epithelial Tumors, Malignant

In brief

The goal of this prospective, single-arm clinical trial is to evaluate the imaging performance and safety of an EpCAM-targeted radiotracer, \[68Ga\]Ga-PN-EpC1, in patients with epithelial tumors. The main questions it aims to answer are: * What is the sensitivity of \[68Ga\]Ga-PN-EpC1 PET/CT for detecting EpCAM-positive tumor lesions? * How does the radiotracer uptake correlate with EpCAM expression assessed by immunohistochemistry? * Is \[68Ga\]Ga-PN-EpC1 safe and well tolerated when administered for PET/CT imaging in patients with epithelial tumors? Participants will undergo \[68Ga\]Ga-PN-EpC1 PET/CT imaging prior to tumor biopsy or surgical resection. Imaging findings will be analyzed and compared with histopathological results and standard imaging assessments. Safety will be evaluated by monitoring adverse events following radiotracer administration.

• Women of childbearing potential must have a negative pregnancy test within 7 days prior to the examination. Male and female patients of reproductive age must agree to use effective contraception during the study and for at least 3 months after the examination.
• Voluntarily participate in the study, demonstrate full understanding of the protocol, and provide written informed consent.

You may not qualify if…

• Severe laboratory abnormalities, including significant impairment of hepatic or renal function, or severe hematological dysfunction.
• History of allergic diseases.
• Patients planning for pregnancy during the study period.
• Pregnant or lactating women.
• Inability to maintain a supine position for at least 30 minutes.
• Patients with claustrophobia or other diagnosed psychiatric disorders that may interfere with compliance.
• Any other condition that, in the opinion of the investigator, may increase the risk to the subject or interfere with the evaluation of the study results.
