Imaging prostate cancer with a new radiotracer

99mTc-QULIC-5-P1 SPECT Imaging in Patients With Prostate Cancer and Compared With 68Ga-PSMA-11 PET

Early Phase 1 Interventional First Affiliated Hospital of Chongqing Medical University · NCT06419348

This study is testing a new imaging agent to see if it can help identify prostate cancer in patients whose tumors have a specific marker called PSMA.

What this trial studies

This clinical trial evaluates the safety and effectiveness of a new radiotracer, 99mTc-QULIC-5-P1, for SPECT imaging in patients with prostate cancer that expresses PSMA. The study aims to determine how well this imaging agent can identify lesions associated with PSMA positive prostate cancer. Participants will undergo imaging procedures to assess the biodistribution of the radiotracer and its potential usefulness in diagnosing prostate cancer. The trial is designed for early-phase evaluation, focusing on the initial safety and imaging capabilities of the agent.

Who should consider this trial

Good fit: Ideal candidates include adults aged 18 and older with suspected or diagnosed prostate cancer that shows PSMA positive expression.

Not a fit: Patients with PSMA negative expression or serious medical conditions that may interfere with the study will not benefit from this trial.

Why it matters

Potential benefit: If successful, this study could enhance the accuracy of prostate cancer diagnosis and improve patient management.

How similar studies have performed: While this specific approach is novel, similar imaging techniques targeting PSMA have shown promise in other studies.
