What this Trial Is About

Researchers are studying a new imaging agent called 18F-fluciclovine to see how well it can detect advanced prostate cancer that has low levels of prostate-specific membrane antigen (PSMA) or shows neuroendocrine features. This pilot study is the first time 18F-fluciclovine is being examined for these specific types of prostate cancer, which are hard to see using standard imaging. The study aims to better understand the role of amino acids and PSMA in these cancers and how imaging tests can improve treatment options. Participants will receive an 18F-fluciclovine PET/CT scan within 6 weeks of their standard care exams, including a 68Ga-PSMA PET/CT scan. Along with the scans, they will have two blood samples collected—one at the time of the 18F-fluciclovine scan and another before starting treatment as decided by their primary oncologist. The radioactive imaging agent 18F-fluciclovine targets amino-acid receptors in tumors and is combined with PET/CT technology to create detailed images. During the study, participants will undergo imaging tests and blood draws to help researchers measure how well 18F-fluciclovine and PSMA show cancer spread in the body over up to six months. The study will closely monitor how these imaging agents are taken up by tumors. Participants must be able to follow study procedures and use contraception due to unknown effects on developing fetuses. The total time involved includes initial imaging and blood testing, with ongoing evaluation of imaging results.

  • At least 5 metastatic lesions present
  • Have had or plan to have standard 68Ga-PSMA PET/CT scan before or after 18F-fluciclovine PET/CT
  • ECOG performance status of 0, 1, or 2 (Karnofsky 60%)
  • Ability and willingness to follow study procedures
  • Agree to use effective contraception before and for 24 hours after PET/CT scan
  • Ability to understand and sign informed consent
Not Eligible

You will not qualify if you...

  • Presence of other active cancers requiring treatment
  • History of allergic reaction to compounds chemically similar to 18F-fluciclovine
  • Uncontrolled illnesses such as active infection, severe heart failure, unstable angina, arrhythmia, or psychiatric conditions limiting study compliance
  • Contraindications to PET/CT such as severe claustrophobia
  • Any condition that may affect study results or pose extra risk as judged by investigators

Your Study Journey

Screening

Duration - 2 to 4 weeks

Participants are screened for eligibility to participate in the trial.

1 visit (in-person)

Diagnostic Evaluation

Duration - Up to 6 weeks

Participants undergo imaging scans including standard 68Ga-PSMA PET/CT and 18F-fluciclovine PET/CT to detect PSMA-low and neuroendocrine prostate cancer.

Sample Collection

Duration - Within the diagnostic period

Participants have two blood tests collected at the time of the 18F-fluciclovine PET/CT scan and prior to treatment as determined by their primary oncologist.

2 blood collection visits (in-person)
