  • Stage IV Prostate Adenocarcinoma


This phase II trial studies how well gallium Ga 68-labeled gastrin-releasing peptide receptor (GRPR) antagonist BAY86-7548 (68Ga-RM2) positron emission tomography (PET)/computed tomography (CT) works in detecting regional nodal and distant metastases in patients with intermediate or high-risk prostate cancer. 68Ga-RM2 PET/CT scan may be able to see smaller tumors than the standard of care CT or magnetic resonance imaging scan.

Study summary:

PRIMARY OBJECTIVES: I. To evaluate 68Ga-RM2 PET/CT for detection of intermediate and high-risk prostate cancer prior to prostatectomy. OUTLINE: Patients receive 68Ga-RM2 intravenously (IV). Within 45-60 minutes, patients undergo a PET/CT scan. Patients may undergo a second PET/CT scan immediately after the first scan for attenuation correction. Patients may undergo also a repeat 68Ga-RM2 PET/CT scan after the completion of their treatment to evaluate response to therapy, if requested by the treating physician. After completion of study, patients are followed up at 24-48 hours and within 3-12 months.


Inclusion Criteria: - Biopsy proven prostate adenocarcinoma - Planned prostatectomy with lymph node dissection - Intermediate to high-risk disease (as determined by elevated PSA [PSA > 10], T-stage [T2b or greater], Gleason score [Gleason score > 6] or other risk factors) - Able to provide written consent - Karnofsky performance status of >= 50 (or Eastern Cooperative Oncology Group [ECOG]/World Health Organization [WHO] equivalent) - Diagnostic CT or magnetic resonance imaging (MRI) performed within 30 days prior to the 68Ga-RM2 PET Exclusion Criteria: - Inability to lie still for the entire imaging time (approximately 30 minutes) - Inability to complete the needed investigational and standard-of-care imaging examinations due to other reasons (severe claustrophobia, radiation phobia, etc.) - Any additional medical condition, serious intercurrent illness, or other extenuating circumstance that, in the opinion of the Investigator, may significantly interfere with study compliance
