18F-Fluciclovine PET/CT Impact on Predicting Clinical Outcome of 177Lu-PSMA-617 Therapy in Patients With Prostate Cancer

Description

This a single-center, prospective, exploratory study. Patients with metastatic castration-resistant prostate cancer (mCRPC) scheduled to undergo Lutetium labelled prostate-specific membrane antigen radioligand therapy (LuPSMA RLT) at the West Los Angeles VA (WLA-VA) will be imaged with a baseline F-18 fluorodeoxyglucose positron emission tomography/computed tomography 18F-FDG PET/CT and a 18F-DCFPyL PET/CT (18F-DCFPyL (2-(3-{1-carboxy-5-\[(6-18F-fluoro-pyridine-3-carbonyl)-amino\]-pentyl}-ureido)-pentanedioic acid)positron emission tomography/computed tomography , as per standard of care in our institution. All patients further undergo eventual follow-up prostate-specific membrane antigen positron emission tomography (PSMA PET) after the 2nd, 4th, and 6th LuPSMA RLT cycle. In this prospective study, an18F-Fluciclovine positron emission tomography/computed tomography ( Axumin PET/CT )will be additionally obtained at baseline (pre-LuPSMA RLT), and after the 2nd, 4th, 6th LuPSMA RLT cycles. Axumin PET/CT will be acquired within 7 days from the PSMA PET. This study is open to Veterans only.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

For general information about clinical research, read Learn About Studies.

Eligibility Criteria

  • * Patients with mCRPC scheduled to undergo LuPSMA RLT.
  • * Willingness to undergo multiple serial PET/CT scans pre- and post-LuPSMA RLT.
  • * Ability of providing written informed consent.
  • * Less than 18 years-old at the time of radiopharmaceutical administration.
  • * Medical condition, serious concurrent illness, or other extenuating circumstance that, in the opinion of the Investigator, may significantly interfere with study procedures or compliance.
  • * Contraindications to LuPSMA RLT.
