About this study

Prostate cancer represents a significant health problem in the United States. This year 179,000 men in the United States will be diagnosed with prostate carcinoma and approximately 25% of them will die of the disease. In addition, the incidence and mortality of prostate carcinoma has been increasing steadily in the United States. Prostate-specific antigen (PSA) levels are commonly used as a biomarker for the detection of prostate cancer. Nonetheless, there is a significant false negative and false positive diagnosis since PSA levels elevate in benign prostatic hyperplasia and prostatitis and decrease in patients taking medications and herbal remedies. Twenty percent of biopsy-proven prostate carcinoma have PSA levels within the normal range, thus confounding the diagnosis based on the PSA screening test. Current diagnostic methods that include transrectal ultrasound (TRUS) and TRUS guided prostate biopsy are logistically difficult and insensitive. These are further complicated by equivocal prostatic biopsy findings such as prostatic intraepithelial neoplasia (PIN) or normal PSA with high clinical suspicion. A tracer with high specificity to prostate cancer related structures at a cellular level would enhance our understanding of the pathophysiology of prostate cancer and would contribute to the detection, localization and quantification of the disease and its metastases. This information will be invaluable in selecting the appropriate treatment regimen.

This study will test the utility of [F-18]FMDHT to image prostate cancer and will evaluate if this radiotracer can differentiate primary prostate cancer in the prostate gland from normal prostate gland itself. More specifically, we will study the distribution kinetics of [F-18]FMDHT in normal healthy humans and in patients with prostate cancer.

As per exploratory IND requirements, we performed toxicity assessment of FMDHT through an outside laboratory (ILS, Inc.) and the results of that study are attached as Appendix A.

Based on our and others data, we hypothesize that:

  1. [F-18]FMDHT PET/CT will distribute initially in various normal tissues following blood flow pattern and will clear rapidly from tissues with no AR.
  2. [F-18]FMDHT PET/CT will detect metastatic disease that expresses AR.
  3. [F-18]FMDHT PET/CT uptake will be elevated in AR-expressing prostate cancer lesions compared to surrounding normal prostate.

In order to progress [F-18]FMDHT into clinic, we are performing a pilot 'first-in-human' biodistribution study in subjects with and without prostate cancer.

What is being measured

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

  1. To map diffusion and clearance rates of this marker in normal and cancerous tissue.

    To obtain first-in-man biodistribution data for [F-18]FMDHT with PET/CT imaging in subjects with and without prostate cancer. The results of these tests will be in the form of scans. Distinguishing characteristics will be how quickly the marker clears from the tissues in the scans.

    Measured: Day 1

Secondary outcomes (1)
  1. To determine if [F-18]FMDHT PET/CT uptake in the primary prostate tumor can be differentiated from normal surrounding prostate that will be confirmed with pathologic staining of biopsy or surgical specimens.

    Measured: Day 1

Questions about this trial

What is this clinical trial studying?

A Early Phase 1 study testing [F-18] fluorinated dihydrotestosterone (FDHT) in people with Prostate Cancer, run by Wake Forest University Health Sciences 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 15 inclusion and 6 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: stopped early, as of the sponsor's last update on 3 Jul 2018. 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?

Early Phase 1 (sometimes called Phase 0) studies give a very small amount of a treatment to a few people, mainly to see how the body handles it.

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

Are results available for this study?

The study was stopped early (reason given: Study tracer can no longer be obtained at our institution). Results are not available in the source record.

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?

To map diffusion and clearance rates of this marker in normal and cancerous tissue. (time frame: Day 1). 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 3 Jul 2018.
