About this study

Official title: A Phase II Study to Evaluate the Performance of PSMA-targeted 18F-DCFPyL PET/CT for the Detection of Clinically Significant Prostate Cancer in Men With an Elevated PSA

This is a phase II, single-center, open-label, trial to evaluate the diagnostic accuracy of PSMA-targeted 18F-DCFPyL PET/CT for detecting clinically significant prostate cancer in a screening population.

Read the detailed description

This is a phase II, single-center, open-label, trial to evaluate the diagnostic accuracy of PSMA-targeted 18F-DCFPyL PET/CT for detecting clinically significant prostate cancer in a screening population. 150 biopsy-naïve patients with an elevated PSA (2-10 ng/mL) will be enrolled in this study.

Within 28 days of informed consent, patients will undergo an 18F-DCFPyL PET/CT. All scans will be read by a single experienced radiologist who will identify regions of interest (ROI) with discrete radiotracer uptake. The maximum SUV value (SUVmax) of each ROI will be recorded. For patients without a detectable ROI, the mean SUV (SUVmean) of a 1-2 cm volume of the prostate will instead be recorded.

One to 28 days following PET/CT imaging, a systematic 12 to 14 core TRUS-guided prostate biopsy will be performed. Immediately following completion of systematic TRUS biopsies, fusion-targeted biopsies of all PET and/or MRI visible lesions will be performed, taking an additional 2 to 3 cores from each radiographic ROI. All biopsy cores will be assessed for Gleason score and percent cancer involvement.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Sensitivity of 18F-DCFPyL PET/CT to detect clinically significant prostate cancer on prostate biopsy relative to serum prostate specific antigen (PSA)

    Measure the diagnostic accuracy of 18F-DCFPyL PET/CT and compare it with serum PSA for detecting clinically significant prostate cancer on prostate biopsy

    Measured: 4 years

Secondary outcomes (3)
  1. Sensitivity of 18F-DCFPyL PET/CT relative to PSA

    Measure the diagnostic accuracy of 18F-DCFPyL PET/CT relative to serum PSA for detecting clinically significant prostate cancer as defined by the following alternative definitions: Gleason score ≥4+3=7; Gleason score ≥3+4 or >50% involvement of ≥1 core with Gleason score ≥3+3=6 prostate cancer; Gleason score ≥3+4 or >70% involvement of ≥1 core with Gleason score ≥3+3=6 prostate cancer; Gleason score ≥3+4=7, or >2 cores with Gleason score ≥3+3=6, or >50% involvement of ≥1 core with Gleason score ≥3+3=6 prostate cancer.

    Measured: 4 years

  2. Sensitivity of 18F-DCFPyL PET/CT for detecting clinically significant prostate cancer relative to mpMRI

    Measure the diagnostic accuracy of 18F-DCFPyL PET/CT relative to mpMRI for detecting clinically significant prostate cancer by the various tested definitions

    Measured: 4 years

  3. Sensitivity and diagnostic accuracy of 18F-DCFPyL PET/CT relative to the phi blood test for detecting clinically significant prostate cancer by the various tested definitions

    Measure the diagnostic accuracy of 18F-DCFPyL PET/CT relative to the phi blood test for detecting clinically significant prostate cancer by the various tested definitions

    Measured: 4 years

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing 18F-DCFPyL Injection in people with Prostate Cancer, run by Sidney Kimmel Comprehensive Cancer Center at Johns Hopkins at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: under way, not looking for participants, as of the sponsor's last update on 30 Mar 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Sensitivity of 18F-DCFPyL PET/CT to detect clinically significant prostate cancer on prostate biopsy relative to serum prostate specific antigen (PSA) (time frame: 4 years). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 30 Mar 2026.
