Study of 68Ga-HBED-PSMA PET/CT and Conventional Imaging in Occult Biological Relapse Prostate Cancer (PSMA REBIOLOC)

May 20, 2021 updated by: Institut Cancerologie de l'Ouest

Diagnostic Multicenter Phase II Study, Prospective, Comparative, of 68Ga-HBED-PSMA PET / CT and Conventional Imaging Procedures in Occult Biological Relapse Prostate Cancer

68Ga-HBED-CC-PSMA is a radiopharmaceutical allowing a new imaging modality for the detection of prostate cancer recurrences, used in recent years in clinical studies by some teams mainly in Europe (1-6 ).

The aim of this study is to study the diagnostic performance of 68Ga-HBED-PSMA PET / CT in occult recurrent carcinoma (PCa) by prospectively comparing it to the standard techniques used in this indication: optimized bone scintigraphy with double TEMP / CT systematic and abdominopelvic MRI. The therapeutic impact and tolerance of this examination will also be evaluated.

The expected results are a demonstration of the superiority of 68Ga-HBED-PSMA PET compared to the standard assessment, with a potential impact on the therapeutic management of patients

Detailed Description

METHODOLOGY:

Phase II imaging study, prospective, multicenter non-randomized.

MAIN OBJECTIVE:

To determine the added value of 68Ga-HBED-CC-PSMA PET / CT in imaging investigations in terms of the sensitivity of detection of biologic suspected prostate cancer recurrence site locations on the elevation of plasma PSA, while all conventional imaging exams are negative or questionable ("occult recurrence")

SECONDARY OBJECTIVE:

  • Evaluate the clinical impact of 68Ga-HBED-CC-PSMA PET / CT in imaging exam by the predicted rate of change in therapeutic attitude.
  • Evaluate the relevance of decisions made after PET / CT 68Ga-HBED-CC-PSMA.
  • Determine the added value of 68Ga-HBED-CC-PSMA PET / CT in terms of specificity and predictive value for detecting secondary locations. This determination will be at the "patient" level and at the "lesion" level
  • To determine the added value of the 2nd PET / CT at 68Ga-HBED-CC-PSMA (2h after the radiopharmaceutical injection) in terms of specificity and predictive value for the detection of secondary locations in relation to the added value of the 1st PET / CT acquisition at 68Ga-HBED-CC-PSMA. This determination will be at the "patient" level and at the "lesion" level.
  • Confirm the perfect tolerance of 68Ga-HBED-CC-PSMA.

STUDY PROCEDURE :

All the imaging sequences will be done in an outpatient setting. There will be no premedication or other treatment before and after 68Ga-HBED-CC-PSMA PET scans. PET / CT will be performed at participating centers on a hybrid PET camera.

68Ga-HBED-CC-PSMA will be administered to the patient by single intravenous injection (Y-infused with isotonic saline infusion) within 60 min of reconstitution of the radiopharmaceutical.

The first TEP 68Ga-HBED-CC-PSMA whole body acquisition starts 60 min after the injection of 150 MBq of 68Ga-HBED-CC-PSMA and continues for 20-30 minutes, the second full-body acquisition of the same duration takes place 120 minutes after the injection is a total duration of 1 hour of imaging and 2:30 to 3:00 in the service.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.

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.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Male

Description

Inclusion Criteria:

  1. Age above 18 years
  2. Diagnosis of histologically proven prostate cancer.
  3. Patient having benefited from previous curative treatment (prostatectomy, radiotherapy, ultrasound, cryotherapy ...), with a significant decrease in the plasma concentration of PSA at the end of treatment (= indisputable PSA)
  4. Biologic recurrence documented by abnormal results in 2 assays of plasma PSA concentration in the same laboratory.
