Gallium-68 PSMA-11 PET in Patients With Biochemical Recurrence

Status Completed

Clinical Trial Summary

This study evaluates the value of Gallium-68 labeled PSMA (68Ga-PSMA) for PET/CT imaging of prostate cancer recurrence. 68Ga-PSMA is a radioactive molecule, which binds to prostate cancer cells. Together with a PET/CT scanner, the distribution of 68Ga-PSMA can be determined in the body. To test this new drug, participants will receive an intravenous injection of Ga-68-PSMA and then have a PET/CT scan. The scan results will be made available to study participants and treating physicians.

Clinical Trial Description

This study evaluates Gallium-68 labelled PSMA-11 (also called Gallium-68 labelled PSMA-HBED-CC, or Gallium-68 labelled PSMA N,N'-bis(2-hydroxybenzyl)ethylenediamine-N,N'-diacetic acid), abbreviated here as 68Ga-PSMA. This molecule (or radiotracer) binds to receptors that are often present on prostate cancer cells. Using 68Ga-PSMA together with a positron emission tomography (PET) scanner (with computed tomography, called PET/CT), it is therefore possible to find prostate cancer lesions in the body. The study will test whether 68Ga-PSMA will identify prostate cancer more precisely than normal imaging methods (for example CT, MRI, or bone scan). A more precise identification of the location of the disease is important. Knowing where the disease is located will help to decide on the best course of action to treat the disease. Men who have elevated tumor markers of prostate cancer are eligible for this study. Participants undergo a 68Ga-PSMA PET/CT scan before further treatment. Based on clinical information, including any prior imaging and biopsy/surgery information and follow-up information, we will determine whether 68Ga-PSMA PET/CT imaging was more accurate than the standard imaging. The study team will collect this information for up to 1 year after the 68Ga-PSMA PET/CT scan. The results of the 68Ga-PSMA PET/CT scan will be shared with the participating patients. Also, results will be entered into the participant's medical record and shared with the treating physicians. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
