Noninvasive imaging to detect PD-L1 in gastrointestinal tumors

PD-L1 Targeting Molecular Imaging of Solid Tumors

Not applicable Interventional Peking University Cancer Hospital & Institute · NCT04629326

This study is testing a new imaging method to see if it can help find a specific marker in gastrointestinal tumors that might show which patients could benefit from certain cancer treatments.

What this trial studies

This study aims to develop a noninvasive imaging technique using WL12 PET/CT to detect PD-L1 expression in tumor lesions of patients with gastrointestinal tumors. By identifying PD-L1 expression, the study seeks to determine which patients may benefit from anti-PD-1/L1 therapies. The approach involves measuring the expression of PD-L1 in solid tumors, which could help tailor treatment strategies for better patient outcomes.

Who should consider this trial

Good fit: Ideal candidates are adults over 18 years old with measurable gastrointestinal tumors and a life expectancy of at least 12 weeks.

Not a fit: Patients with significant hepatic or renal dysfunction, or those who cannot tolerate the imaging procedure, may not benefit from this study.

Why it matters

Potential benefit: If successful, this could lead to more personalized treatment options for patients with gastrointestinal tumors.

How similar studies have performed: While this approach is innovative, similar studies targeting PD-L1 expression have shown promise in other cancer types, suggesting potential for success.
