Imaging tumors using a new dual-target agent

68Ga-RM26-RGD PET/CT Imaging in the GRPR and αvβ3 Positive Tumor Patients

Early Phase 1 Interventional Peking Union Medical College Hospital · NCT05549024

This study is testing a new imaging agent to see if it can help doctors get a clearer picture of tumors in patients with breast, brain, and prostate cancers compared to standard imaging methods.

What this trial studies

This study evaluates the effectiveness of a novel dual-target imaging agent, 68Ga-RM26-RGD, for PET/CT imaging in patients with breast, brain, and prostate cancers. The approach aims to improve tumor visualization by targeting specific receptors that are highly expressed in malignant tissues and their associated neovascularization. By comparing this new agent with conventional imaging methods, the study seeks to enhance diagnostic accuracy for tumors that typically show low uptake in standard imaging. Patients will undergo PET/CT scans using both the new agent and traditional imaging agents to assess the clinical application value of this dual-target approach.

Who should consider this trial

Good fit: Ideal candidates include patients with confirmed or suspected breast, brain, or prostate cancer who can provide informed consent.

Not a fit: Patients who are pregnant, breastfeeding, or have medical conditions that may interfere with study compliance will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved diagnostic accuracy for certain types of cancer, allowing for better treatment planning.

How similar studies have performed: While conventional imaging methods have been widely used, this dual-target approach is novel and has not been extensively tested in prior studies.
