Investigational imaging for detecting glioma recurrence or progression

GA-68 PSMA-11 PET To Evaluate Malignant Glioma Recurrence - A Pilot Study

Phase 2 Interventional Mayo Clinic · NCT06444412

This study is testing a new type of imaging to see if it can better tell the difference between glioma recurrence and progression in patients with advanced gliomas, which could help avoid unnecessary surgeries.

What this trial studies

This clinical trial evaluates the effectiveness of gallium-68 (Ga-68) PSMA-11 PET/CT imaging in distinguishing between glioma recurrence and progression after initial treatment. Patients with WHO Grade 3 or 4 gliomas will receive Ga-68 PSMA-11 intravenously, followed by a PET/CT scan to assess tumor activity. The study aims to improve diagnostic accuracy by correlating imaging findings with tumor pathology and treatment effects, potentially reducing the need for invasive procedures like surgery. Safety and tolerability of the imaging technique will also be evaluated.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older with a history of WHO Grade 3 or 4 infiltrating glioma who have undergone first-line treatment and have MRI findings suggestive of recurrent disease.

Not a fit: Patients who have received antiangiogenic therapy or cannot undergo a PSMA PET/CT scan due to physical limitations will not benefit from this study.

Why it matters

Potential benefit: If successful, this imaging technique could lead to more accurate diagnoses and better treatment decisions for patients with glioma.

How similar studies have performed: Other studies have shown promise in using PSMA PET imaging for various cancers, but this specific application in glioma is relatively novel.
