FACBC PET/CT for Recurrent Prostate Cancer

June 17, 2016 updated by: David M. Schuster, MD

18F-FACBC PET-CT for the Detection and Staging of Recurrent Prostate Carcinoma (CA129356-01).

Hypothesis:Anti-[18F]FACBC PET-CT will adequately detect local and extraprostatic recurrence, and lead to better characterization of disease status in restaging patients.

This is a study that will test a compound (chemical substance) that has a small amount of radioactivity attached to it. This substance has a natural tendency to go to prostate tissue. The substance is called [18]FACBC and it is given in the form of an injection into a vein. After the substance reaches the prostate, scans called PET or Positron Emission Tomography, are done. This is similar to having CAT scans or x-rays. Usually a compound called [18]FDG is used for PET scans but this substance is eliminated by the kidneys and cannot reach the prostate. This substance called [18]FACBC is not eliminated by the kidneys and may allow tumors in the prostate to be seen better. It is sometimes difficult to tell if a growth on the prostate is cancer with scans or x-rays that are usually done.

Anti-[18F]FACBC PET-CT will be compared to ProstaScint (In-capromab pendetide) which is the conventional imaging for prostate cancer. Investigators will be blinded of the intervention.

This study will look at how the [18]FACBC goes into the prostate tissue and determine its ability to detect recurrent prostate cancer.

Description

STUDY NOW CLOSED for recruitment

Inclusion Criteria:

  • Patients must be 18 years of age or older.
  • Patients will have been originally diagnosed with localized (Stage T1c, T2, or T3 ) prostate carcinoma and have undergone what was considered definitive therapy for localized disease.
  • In the case of brachytherapy, cryotherapy, or external beam radiation, treatment will have occurred at least 2 years in the past to eliminate patients with so-called "PSA bump."
  • Patient will have suspicion of recurrent prostate carcinoma as defined by: ASTRO criteria of three consecutive rises of PSA or earlier if clinically appropriate, and/or nadir + 2.0 after radiotherapy, and/or greater than 0.3 after prostatectomy.
  • Ability to lie still for PET scanning
  • Patients must be able to provide written informed consent.

Exclusion Criteria:

  • Age less than 18.
  • Greater than T3 disease in past
  • Prior prostatectomy or 2 years since brachytherapy, cryotherapy, or external beam radiation therapy.
  • Does not meet above criteria of suspicious PSA elevation
  • Inability to lie still for PET scanning
  • Cannot provide written informed consent.
  • Bone scan findings characteristic for metastatic prostate carcinoma
  • Less than 2 months since any prior prostate biopsy (to decrease false positive uptake from inflammation).

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Other: FACBC PET-CT and ProstaScint CT
Participants diagnosed with localized prostate carcinoma with subsequent definitive therapy or suspicion of recurrent cancer will undergo an FACBC PET-CT scan and the ProstaScinct CT.
Anti-3-[18F]FACBC is an investigational positron emission tomography (PET) radiotracer being studies given intravenously prior to PET scan
Other Names:
  • Fluciclovine
ProstaScint (In-Capromab Pendetide) is used to image the extent of prostate cancer in standard practice. Capromab is a mouse monoclonal antibody which recognizes prostate specific membrane antigen from prostate cancer cells and normal prostate tissue. It is given intravenously prior to undergoing CT imaging.
Other Names:
  • In-Capromab Pendetide
