An Investigational Scan (Ga-68 PSMA-11 PET/CT) for the Detection of Therapy Response in Patients With Metastatic Adenoid Cystic Carcinoma

• Status: COMPLETED
• Trial end date: 2025-08-12

Summary

This phase II trial tests whether gallium-68 (Ga-68) prostate specific membrane antigen (PSMA)-11 positron emission tomography (PET)/computed tomography (CT) imaging is useful for detecting therapy response in patients with adenoid cystic carcinoma (salivary gland cancer) that has spread from where it first started (primary site) to other places in the body (metastatic). The PET scan detects and takes pictures of where the radioactive imaging agent (68Ga PSMA-11) has gone in the body and the CT scan uses x-rays to create images of the bones and internal organs within the body. Combining a PET scan with a CT scan can help make the images easier to interpret. This study may help researchers learn whether GA-68 PSMA-11 PET/CT is useful for detecting treatment response and guiding treatment decisions in patients with metastatic adenoid cystic carcinoma.
