Prostate Cancer Clinical Trial

68Ga-PSMA-11 PET/CT Screening Prior to 177Lu-PSMA-617 Therapy for Patients With Metastatic Castrate Resistant Prostate Cancer

Summary

This phase III study provides access to 68Ga-PSMA-11 positron emission tomography (PET)/computed tomography (CT) imaging for patients with castrate-resistant prostate cancer that has spread to other places in the body (metastatic) being considered for177Lu-PSMA-617 therapy. T PET is an established imaging technique that utilizes small amounts of radioactivity attached to very minimal amounts of this tracer. CT utilizes x-rays that traverse body from the outside. CT images provide an exact outline of organs and potential inflammatory tissue where it occurs in patient's body. Combining a PET scan with a CT scan can help make the images easier to interpret. The 68Ga-PSMA-11 PET/CT scan is done with a very small amount of radioactive tracer call 68- gallium PSMA-11. In patients that have been diagnosed with prostate cancer, a protein called prostate-specific membrane antigen (PSMA) appears in large amounts on the surface of the cancerous cells. The radioactive imaging agent (68Ga-PSMA-11) has been designed to circulate through the body and attach itself to the PSMA protein on prostate cancer cells. A PET/CT scan is then used to detect the location of prostate cancer lesions. By gaining access to 68Ga-PSMA-11 PET/CT scans, patients may be safely screened for 177Lu-PSMA-617 therapy in the treatment of metastatic castrate resistant prostate cancer.

Full Description

PRIMARY OBJECTIVE:

I. To overcome a clinical access issue that would otherwise block patients from reimbursement of a new cancer therapy, and therefore block or significantly delay their care.

OUTLINE:

Patients receive gallium Ga 68 gozetotide intravenously (IV) and then undergo a positron emission tomography (PET)/computed tomography (CT) scan throughout the trial.

View Eligibility Criteria

Eligibility Criteria

Inclusion Criteria:

An adult male patient who is actively under the care of a medical oncology, radiation oncology or urology physician at Mayo Clinic

An adult male patient who is deemed eligible (or potentially/likely eligible) for PSMA-targeted radionuclide therapy by a nuclear medicine physician or Radiologist in the nuclear medicine therapy practice, or by the Prostate Theranostic Tumor Board (PTuB)

Eligibility will be documented in the medical record by the clinical practice
It is acceptable for the patient to be eligible for PSMA-targeted radionuclide therapy in all regards except for having completed a PSMA-targeted PET scan showing PSMA-positive prostate cancer
It is acceptable for a patient to be potentially eligible for therapy, but have a relative contraindication, such as a minor laboratory abnormality, and be on the list for discussion at the PTuB in the future
An adult male patient who has not received a 68Ga-PSMA-11 PET/CT or PET/magnetic resonance (MR), or for whom a repeat 68Ga-PSMA-11 PET/CT exam is needed per the clinical practice to ensure eligibility
An adult male patient who does not otherwise have access to a reimbursable clinical 68Ga-PSMA-11 PET scan
An adult above the ages of 18

Exclusion Criteria:

A patient who is unable to consent per Mayo guidelines
A patient who is unable to lay still, or otherwise successfully complete the imaging exam
