Biochemically Recurrent Prostate Cancer Detection With Integration of PSMA PET imaging and Extracellular Vesicle-Based Tumor Monitoring

Overview

About this study

The purpose of this study is to develop an inexpensive and non-invasive blood test that can help refine the identification of patients with PSMA-positive metastatic lesions following biochemical recurrence. 

Participation eligibility

Participant eligibility includes age, gender, type and stage of disease, and previous treatments or health concerns. Guidelines differ from study to study, and identify who can or cannot participate. There is no guarantee that every individual who qualifies and wants to participate in a trial will be enrolled. Contact the study team to discuss study eligibility and potential participation.

Inclusion Criteria:

  • Male with original diagnosis of adenocarcinoma of the prostate following definitive therapy.
  • Men with Biochemical Recurrence (defined below) and planned to undergo PSMA PET imaging:
    • After radiotherapy or cryotherapy: 3 consecutive PSA rises and/or PSA rise by 2.0 ng/mL or more above nadir (ASTRO-Phoenix);
    • After prostatectomy, PSA > 0.2 ng/mL on 2 or more determinations (American Urological Association).
  • Life expectancy of 6 months or more as judged by the investigator.
  • Willing and able to undergo all study procedures.
  • Informed consent in writing (dated and signed).

Exclusion Criteria:

  • Age: less than 18 years.
  • Variant prostate pathology including but not limited to :
    • Small cell prostate cancer;
    • Ductal prostate cancer;
    • Neuroendocrine prostate cancer.
  • Prior focal therapy for prostate cancer.
  • Prior neoadjuvant therapy for prosate cancer.
  • Contraindications to any of the ingredients of PET.
  • Close affiliation with the investigational site; e.g., first-degree relative of the investigator.
  • Mental conditions rendering the subject incapable to understand the nature, scope, and consequences of the trial.
  • Being clinically unstable or requiring emergency treatment.
  • Patients who are unable to undergo a PET/CT scan (e.g., patients who are extremely obese, unable to lie flat or remain still, or have uncontrollable claustrophobia).

Note: Other protocol defined Inclusion/Exclusion Criteria may apply.
