Role of rhPSMA-7.3 PET/CT Imaging in Men With High-Risk Prostate Cancer Following Conventional Imaging and Associated Changes in Medical Management
Sponsor:

MidLantic Urology

Brief Summary:

Study Title: Role of rhPSMA-7.3 PET/CT imaging in men with High-Risk prostate cancer following conventional imaging and associated changes in medical management Protocol number: BED-IIT-437 Phase: 3b Sponsor: MidLantic Urology Funding Organization: Blue Earth Diagnostics Ltd Study Design: This is a Phase 3b, multi-center, single-arm, diagnostic imaging study designed to detect metastatic lesions in men diagnosed with high-risk prostate cancer.

Condition or disease

Prostate Cancer

Intervention/treatment

rhPSMA-7.3 (18F)

Phase

PHASE3

Detailed Description:

Consented patients will be screened to determine eligibility for the study prior to investigational product (IP) administration. In addition to their routine clinical work-up, which will include 99mtechnetium-biphosphonate bone scan and abdominal/pelvic computed tomography (CT) or magnetic resonance imaging (MRI) and chest CT per local practice, and before the scheduled radical prostatectomy (RP) and pelvic lymph node dissection (PLND), or radical pelvic radiation therapy, patients will receive 8 mCi (296 MBq) ± 20% rhPSMA-7.3, delivered as an intravenous (IV) bolus injection, followed by PET imaging. For each patient, the PET imaging results will be reported to the responsible physician prior to the planned treatment. Imaging results and further procedures/treatment plan should be discussed with the patient within 7 days after rhPSMA-7.3 imaging (this may be conducted by telephone at the clinician's discretion). Within 45 days post-IP administration, the patient will receive treatment as follows: * Standard of care surgical treatment of PCa, including PLND; or * If the rhPSMA-7.3 PET scan detects M1 lesion(s): * A biopsy/surgery and/or additional imaging to confirm M1 lesion(s) will be required prior to initiation of treatment. The purpose of this study is to assess the accuracy of rhPSMA-7.3 PET/CT with conventional imaging for detecting metastatic disease in men with high-risk prostate cancer and the impact on medical management of these men. Accurate staging of newly diagnosed PCa assists in directing appropriate treatment strategies. In patients with high-risk PCa, the primary goal of imaging is to detect extra-prostatic disease. The identification of metastatic disease may significantly change the planned treatment regimen from locoregional to systemic therapy

Criteria
Inclusion Criteria
  • 1. Patient willing to provide signed informed consent and willing to comply with all required study schedule events, where safe and feasible.
  • 2. Patient is male and aged \>18 years old.
  • 3. Histologically confirmed adenocarcinoma of the prostate.
  • 4. High risk prostate cancer. High-risk patients will be defined as having any of the following criteria: primary Gleason grade 4, or any Gleason grade 5, PSA ≥20, or clinical stage T3a (per NCCN Guidelines Version 2.2019; PROS-2).
Exclusion Criteria
  • 1. Patients with any medical condition or circumstance (including receiving an IP) that the investigator believes may compromise the data collected or lead to a failure to fulfil the study requirements.
  • 2. Patients who are planned to have an x-ray contrast agent or other PET radiotracer \<24 hours prior to the PET scan.
  • 3. Patients currently receiving, or with a prior history of, androgen deprivation therapy (ADT; defined as surgical orchidectomy; luteinizing hormone-releasing hormone \[LHRH\] agonist alone \[continuous or intermittent\]; LHRH antagonist alone \[continuous or intermittent\]; administration or use of a first generation or second generation anti-androgen alone or in combination with an LHRH agonist/antagonist).
  • 4. Patients participating in an interventional clinical trial within 30 days and having received an IP within five biological half-lives prior to administration of rhPSMA-7.3.
