January 8, 2025 updated by: Istituto Romagnolo per lo Studio dei Tumori Dino Amadori IRST S.r.l. IRCCS

68Ga-PSMA, N,N'-Bis(2-hydroxybenzyl)Ethylenediamine-N,N'-Diacetic Acid (HBED)-PET/CT in the Evaluation of the Biochemical Relapse in Patients With a History of Prostate Cancer Radically Treated

Single-center, prospective, diagnostic trial in radically treated patients with biochemical recurrence of prostate cancer. Patients with radically treated prostate cancer with biochemical relapse and negativity of all traditional morphological and functional imaging (transrectal ultrasound, bone scan, 18F-FMC PET/CT, CT/MRI) or doubtful imaging of 2-deoxy-2-[fluorine-18] (18F)-fluoromethylcholine (FMC) PET/CT will receive a Gallio-68 (68Ga)- Prostate Specific Membrane Antigen (PSMA) Positron Emission Tomography (PET)/Computed Tomography (CT) scan.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Single-center, prospective, diagnostic trial. The primary objective of this study is to evaluate the sensitivity of 68Ga-PSMA PET /CT defined as the ratio between the number of 68Ga-PSMA PET /CT positive patients and the number of prostate cancer patients with biochemical relapse and negative standard imaging.

The secondary objectives are:

  • Sensitivity for different Prostatic Specific Antigen (PSA) values (ranges)
  • Sensitivity for different lesion sites
  • Treatment response assessment with a second PET
  • False positives detection during Follow Up (FUP) (with other standard methods and eventually optional biopsy) for patient without any treatment
  • safety 67 evaluable patients will be injected with 100-200 megabecquerel (MBq) 68Ga-PSMA intravenously

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. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

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

19 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

  1. Patients must have histologically or cytologically confirmed prostate cancer
  2. Male, aged >18 years.
  3. Radical treatment for prostate cancer (radiotherapy or surgery)
  4. 18F-FMC PET/CT negative or doubtful
  5. Negativity of all the other traditional morphological and functional imaging (transrectal ultrasound, bone scan, CT/MRI)
  6. Patients with PSA progression defined as PSA ≥ 1,0 ng/mL and/or PSA rising defined as 2 subsequent values showing PSA increase at least 1 week apart.
  7. Male participants whose partner is of child bearing potential must be willing to ensure that they or their partner use effective contraception during the study and for 3 months thereafter
  8. Participant is willing and able to give informed consent for participation in the study.

Exclusion Criteria:

  1. No hormonotherapy in the last 6 months
  2. No radiotherapy in the last 6 months.
  3. Patients with PSA < 1.0 ng/ml

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure

up to 24 months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
