Is this trial a fit for you?

Likely a good fit

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

Probably not a fit

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

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

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.

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