What this trial studies

This study evaluates the effectiveness of 68Ga-PSMA-11 PET/CT scans in measuring tumor activity in adults with high-grade glioma or brain metastases. Participants must be 18 years or older and have confirmed cases of these conditions, with lesions suitable for biopsy. The study aims to improve the understanding of tumor uptake in cancerous tissues, which could enhance treatment planning and outcomes. The intervention involves administering the PET scans to assess the tumors.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older with confirmed high-grade glioma or brain metastases who are scheduled for biopsy or resection.

Not a fit: Patients who cannot undergo a PET scan due to medical conditions or those who are pregnant or nursing may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to better assessment and management of brain tumors, improving patient outcomes.

How similar studies have performed: Other studies using PET scans for tumor assessment have shown promise, indicating potential success for this approach.

Eligibility criteria

Inclusion Criteria:

* Ability to understand and the willingness to sign (or their legally acceptable representative (LAR) must sign) a written informed consent document
* Adults ≥ 18 years old
* Suspicion for or histologically or cytologically confirmed and previously treated HGG or brain metastases from a primary extracranial malignancy
* Lesion size ≥ 1 cm (for the lesion to be biopsied)

Exclusion Criteria:

* Inability to undergo a PET scan (e.g., claustrophobia or noncompatible implant in case PET/MR is performed)
* Pregnant or nursing female. All women of childbearing potential must have a documented negative serum or urine pregnancy test \<1 week before study.
* Uncontrolled, intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiacarrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements.
