PSMA PET Imaging of Recurrent Prostate Cancer

August 25, 2026 updated by: Memorial Sloan Kettering Cancer Center
The purpose of this study is to see if a new diagnostic research agent named 68Ga-HBED-CC-PSMA can show prostate cancer on a PET/CT scan that cannot be seen on other standard imaging even when the PSA levels are very low.

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

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  • Biopsy proven adenocarcinoma of the prostate
  • Initially treated with definitive local therapy (surgery and radiation therapy are the most common treatments, but other treatments are also eligible)

  • For patients initially treated with surgery, radiation therapy, brachytherapy, or cryotherapy:

    • PSA ≥ 0.2 ng/mL in at least two consecutive tests within 6 months of date of consent for patients
    • Note: The most recent PSA value must be within 6 weeks of consent

  • For patients who have received additional treatment in the recurrent or metastatic setting:

    ° PSA ≥ 2 ng/ml above the most recent therapy nadir

  • Age ≥ 18 years
  • Patient must be able to tolerate PET/CT or PET/MR imaging

Exclusion Criteria:

  • Patient with claustrophobia that would preclude PET/CT or PET/MR imaging or other contraindications to CT imaging.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
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.
Active Comparator: Ga-HBED-iPSMA PET with CT or MRI
Participants will have a PET scan with Ga-HBED-iPSMA. PET may be combined with CT or MRI at the discretion of the referring clinician.
Drug: Ga-HBED-iPSMA PET
Patients will be injected with 100-300 MBq of 68Ga-HBED-iPSMA and after a waiting of 60-90 minutes patients will be scanned from mid-skull to mid-thigh.
Diagnostic test: PET/CT
PET/CT will be acquired using a GE 710 or 690 time-of-flight PET/CT scanner. Following a waiting period of 60-90 minutes post 68Ga-HBED-iPSMA administration, patients will be scanned from top of the skull to mid-thigh. Images will be acquired with patients in a supine position with their arms raised above their head. If patients cannot raise their arms above the head, the arms will be comfortably positioned and secured by the side of the patient. The PET may be combined with a CT scan as a PET/CT or a MRI scan as PET/MR.
Diagnostic test: MRI
Patients may undergo a diagnostic MRI of the prostate, other body parts or a whole-body MRI at the same imaging session as clinically indicated.
Active Comparator: Ga-HBED-iPSMA PET with MRI
Participants will have a PET scan with Ga-HBED-iPSMA and will be combined with MRI. If PET/MR imaging is not available, PET/CT imaging may be substituted. This arm will be closed to accrual and these patients will be analyzed separately.
Drug: Ga-HBED-iPSMA PET
Patients will be injected with 100-300 MBq of 68Ga-HBED-iPSMA and after a waiting of 60-90 minutes patients will be scanned from mid-skull to mid-thigh.
Diagnostic test: MRI
Patients may undergo a diagnostic MRI of the prostate, other body parts or a whole-body MRI at the same imaging session as clinically indicated.

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
Time Frame
Disease localization by PSMA PET/MR
Time Frame: 2 years
2 years

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.
Outcome Measure
Measure Description
Time Frame
PSA relapse free survival in patients undergoing PSMA PET/MR guided SRT
Time Frame: 2 years
2 years
Incidence of Treatment-Emergent Adverse Events assessed by common terminology criteria for adverse events (CTCAE v4.0)
Time Frame: 2 years
The safety and tolerability of 68Ga-HBED-iPSMA will be followed by assessing the incidence, nature and severity of toxicities by common terminology criteria for adverse events (CTCAE v4.0)
