August 17, 2018 updated by: Sidney Kimmel Comprehensive Cancer Center at Johns Hopkins

Evaluation of 18F-DCFBC PSMA-based PET Imaging for Detection of Metastatic Prostate Cancer.

This research is being done to see if an investigational radioactive drug called 18F-DCFBC can help us find cancer that has spread (metastatic disease) from its original site in people who have cancer in their prostate to other parts of their body.

Study Overview

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

The objective of this study is to evaluate a radiolabeled urea-based small molecule inhibitor of prostate-specific membrane antigen (PSMA), [18F]DCFBC (DCFBC) PET imaging for detection of metastatic prostate cancer. PSMA is a well characterized histological marker of prostate cancer tumor aggressiveness and metastatic potential. The investigators propose to assess the ability of DCFBC PET to detect metastatic prostate cancer by visual qualitative and quantitative SUV analysis. Correlation will be made to sites of suspected metastatic disease detected by standard conventional imaging modalities (CIM) for prostate cancer which includes IV contrast CT of chest/abdomen/pelvis and whole body bone scintigraphy.

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 to 100 years (ADULT, OLDER_ADULT)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Male

Inclusion Criteria:

  1. Histological confirmation of prostate cancer

  8. Patients or their legal representatives must have the ability to read, understand and provide written informed consent for the initiation of any study related procedures

Exclusion Criteria:

  1. Patient has been treated with an investigational drug, investigational biologic, or investigational therapeutic device within 14 days prior to study radiotracer administration
  2. Prior radiation therapy, chemotherapy, or androgen-deprivation therapy within 2 weeks prior to study radiotracer administration (Washout is one half-life of the drug or 2 weeks, whichever is longest)
  3. Initiation of new therapy for progressive metastatic disease since radiographic documentation of progression.
  4. Serum creatinine > 3 times the upper limit of normal
  5. Total bilirubin > 3 times the upper limit of normal
  6. Liver Transaminases > 5times the upper limit of normal
  7. Unable to lie flat during or tolerate PET/CT

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.
EXPERIMENTAL: 18F-DCFBC
Participants with hormone-naive prostate cancer (HNPC) and castration-resistant prostate cancer (CRPC) with metastatic lesions detected on conventional imaging modalities (contrast-enhanced computed tomography [CECT] and bone scintigraphy [BS]) undergo PET imaging with 18F-DCFBC radiotracer.
Drug: 18F-DCFBC

18F-DCFBC is a radiofluorinated small-molecule inhibitor of prostate-specific membrane antigen (PSMA).

A bolus of 10 mCi (370 MBq) [9-11 mCi (333-407 MBq)] of 18F-DCFBC will be injected into the IV line by slow IV push.

  • N-[N-[(S)-1,3-dicarboxypropyl]carbamoyl]-4-18F-fluorobenzyl-L-cysteine

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
Measure Description
Time Frame
Measurement of Sensitivity of DCFBC-PET as Determined by Agreement of PET/CT Detection of Metastatic Prostate Cancer With Conventional Imaging Modality (CIM)
Time Frame: 24 Months
Measurement of sensitivity of DCFBC PET to CIM (contrast-enhanced CT and bone scintigraphy) for detection of metastatic prostate cancer based on number of lesions that are detected on PET/CT, in agreement with CT and CIM. Measurement of sensitivity were obtained on lesion by lesion analysis where lesions that responded on follow up were considered a true positive.
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.
Outcome Measure
Measure Description
Time Frame
Sensitivity of Detection of New or Progression of Metastasis
Time Frame: up to 1 year
Sensitivity of DCFBC-PET and conventional imaging modalities (CIM), which include bone scintigraphy (BS) and contrast-enhanced computed tomography (CECT) to detect new or progression of metastases at follow-up, where "equivocal" lesions are considered negative. Measurement of sensitivity were obtained on lesion by lesion analysis where lesions that responded on follow up were considered a true positive, therefore, sensitivity is a proportion of responsive lesions to the total number of lesions analyzed.
up to 1 year
