An Investigational Scan (Ga-68 PSMA-11 PET/CT) for Detection of Disease Recurrence or Progression in Patients With Glioma

Study Purpose

This clinical trial evaluates whether gallium-68 (Ga-68) prostate specific membrane antigen (PSMA)-11 positron emission tomography (PET)/computed tomography (CT) imaging is useful in differentiating between disease that has come back after a period of improvement (recurrence) or that is growing, spreading, or getting worse (progression) and treatment effect in patients with glioma. Patients with glioma undergo frequent imaging for assessment of disease status. After first-line treatment however, the correlation between imaging findings and tumor activity can be confused, and surgery is often required for definitive diagnosis. The PET/CT scanner is an imaging machine that combines 2 types of imaging in a single scan. The PET scanner detects and takes pictures of where the radioactive imaging agent (68Ga PSMA-11) has gone in the body and the CT scanner uses x-rays to take structural pictures inside the body. PSMA PET also binds to neoplastic blood vessels, including those in gliomas. This study may help researchers learn whether GA-68 PSMA-11 PET/CT is useful for improving detection of tumor recurrence or progression, as opposed to treatment effects, in patients with gliomas.

Recruitment Criteria

Accepts Healthy Volunteers

Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms

No
Study Type

An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.


An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.


Searching Both is inclusive of interventional and observational studies.

Trial Details

Trial ID:

This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.

NCT06444412
Phase

Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.

Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.

Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.

Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.

Additional Details

PRIMARY OBJECTIVE:

  • I. To assess uptake of Ga-68 labeled PSMA-11 in regions of high tumor cell density (tumor recurrence) and low tumor cell density/treatment effect to determine whether PSMA-11 uptake differs significantly between true tumor progression versus (vs.#46;) in radiation treatment effects.
SECONDARY OBJECTIVE:
  • I. To evaluate the immediate safety and tolerability of PSMA PET in patients with glioma.
EXPLORATORY OBJECTIVES:
  • I. To identify optimal maximum standardized uptake value (SUVmax) thresholds for differentiating viable tumor from treatment effect.
  • II. To perform a radiology-pathology correlation of PSMA uptake at PET with tumor PSMA immunohistochemistry (IHC) immunostaining, tumor pathology features, and signal and enhancement characteristics at magnetic resonance imaging (MRI) (no research MRI will be obtained, based on MRI images obtained for clinical use).
  • III. To evaluate the added diagnostic value of gallium Ga 68 (Ga-68 PSMA-11) PET beyond MRI (using information from a clinical MRI[s] obtained prior to enrollment in the study) for detecting viable enhancing tumor from treatment effects.
OUTLINE: Patients receive Ga-68 PSMA-11 intravenously (IV) and then undergo PET/CT over 1 hour, 50-100 minutes after injection.
