Clinical Use of 68Ga PSMA-11 PET/CT in Diagnosing, Staging and Restaging Prostate Cancer

September 6, 2023 updated by: Dana Mathews

Clinical Use of 68Ga Prostate Specific Membrane Antigen-11 Positron Emission Tomography With Computed Tomography in Diagnosing, Staging and Restaging Prostate Cancer

The purpose of this protocol is to provide 68Ga Prostate Specific Membrane Antigen-11 (68Ga PSMA-11) for clinical use in the diagnosis, staging and restaging of prostate cancer using Positron Emission Tomography with Computed Tomography (PET/CT) prior to its full local Federal Drug Administration (FDA) approval. Extensive research has shown that 68Ga PSMA-11 PET/CT offers higher detection rate of metastatic disease in prostate cancer than the current standard of care usually used in staging and restaging prostate cancer.

Detailed Description

68Ga PSMA-11 PET/CT offers higher detection rate of metastatic disease in prostate cancer than the current standard of care of computed tomography (CT), magnetic resonance imaging (MRI), and bone scintigraphy usually used in staging and restaging prostate cancer. Furthermore, 68Ga PSMA-11 PET/CT offers a higher detection rate of primary and metastatic prostate cancer compared to other available radiotracers used for prostate cancer. It additionally offers enhanced imaging characteristics of greater sensitivity at lower prostate specific antigen (PSA) values and higher target to background ratios than currently available radiotracers. For these reasons, we feel that expanded access to 68Ga PSMA-11 offers better patient care at comparable cost to standard imaging.

The population to be treated consists of men in whom metastatic or recurrent prostate cancer is suspected. Patients will be recruited primarily from the clinical practices of the University of Texas Southwestern Medical Center (UTSW) and Parkland Health and Hospital System. Additional patients may be referred for recruitment from physicians outside UTSW.

Each patient will receive an IV injection of 68Ga PSMA-11 as a bolus intravenous injection. Depending on patient medical history and Radiology physician preference, the patient may also be injected with 20 milligrams (mg) of furosemide to encourage urination, and the patient will void immediately prior to getting on the scan table. Patients will be scanned on a PET/CT scanner. The patient will be positioned with arms elevated above the head.
