Using a special probe for PET imaging of solid tumors

CLDN18.2 Targeting Nanobody Probe for PET Imaging in Solid Tumors

NA · Peking University Cancer Hospital & Institute · NCT05436093

This study is testing a new imaging method to see if a special probe can help find certain solid tumors in patients so they can get better-targeted treatments.

What this trial studies

This study aims to develop a noninvasive PET/CT imaging technique using a 68Ga-ACN376 probe to detect the expression of CLDN18.2 in solid tumors. By identifying patients with measurable tumor lesions, the study seeks to determine who may benefit from targeted treatments against CLDN18.2. The approach focuses on enhancing the accuracy of tumor characterization and treatment planning for affected individuals.

Who should consider this trial

Good fit: Ideal candidates include adults over 18 years old with solid tumors and at least one measurable target lesion.

Not a fit: Patients with significant hepatic or renal dysfunction, or those who are pregnant, may not benefit from this study.

Why it matters

Potential benefit: If successful, this could lead to improved detection and treatment options for patients with solid tumors expressing CLDN18.2.

How similar studies have performed: While this approach is innovative, similar studies using targeted imaging for tumor characterization have shown promise in the past.
