About this study

Official title: 18F-Fluciclovine PET CT as an Indicator of Therapeutic Response in Metastatic Prostate Carcinoma (M1PCa)

This phase IV trial studies how well an investigational scan (18F-fluciclovine PET-CT) works for the measurement of therapeutic response in patients with prostate cancer that has spread to other places in the body (metastatic). 18F-fluciclovine is a radioactive substance that is used in this study with PET-CT imaging scans that may help doctors learn about response to standard therapy in patients with prostate cancer.

Read the detailed description

PRIMARY OBJECTIVE:

  1. Evaluate metabolic response by fluciclovine F18 (18F-fluciclovine) PET qualitatively and semi-quantitatively with standardized uptake values (SUV) following androgen deprivation therapy (ADT) plus abiraterone at 22-28 weeks (+/- 4 weeks), and correlate the findings with size changes as defined by conventional imaging and prostate-specific antigen (PSA) response.

SECONDARY OBJECTIVES:

  1. To correlate pelvic 18F-fluciclovine PET imaging findings with pathologic findings at radical prostatectomy and pelvic lymph node dissection to determine 18F-fluciclovine PET imaging sensitivity and specificity for pelvic lymph node cancer involvement.

II. To evaluate 18F-fluciclovine PET imaging response and its correlation with progression free survival (defined by Prostate Cancer Working Group 2 [PCWG2] criteria).

III. To determine if sites of progressive disease develop at the initial/prior site (diagnostic site) of metastases or in newly developed sites at the time of metastatic progression.

IV. To evaluate metabolic response by 18F-fluciclovine PET semi-quantitatively with target to blood pool ratio (TBR) following ADT plus abiraterone at 22-28 weeks (+/- 4 weeks), and correlate the findings with size changes as defined by conventional imaging and PSA response.

OUTLINE:

Within 4 weeks before starting standard systemic therapy (SST), patients receive fluciclovine F18 intravenously (IV) then undergo a PET-CT scan over 30 minutes. Within 22-28 weeks after starting SST, patients receive fluciclovine F18 IV and undergo a second PET-CT scan over 30 minutes.

What is being measured

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

  1. Metabolic Response by Fluciclovine F18 (18F-fluciclovine) Positron Emission Tomography (PET) With Standardized Uptake Values (SUV)"

    Will evaluate metabolic response by 18F-fluciclovine PET qualitatively and semi-quantitatively with SUV and correlate the findings with size changes as defined by conventional imaging prostate specific antigen (PSA) response. The percentage of change in the 18F-fluciclovine maximum standardized uptake value (SUVmax) after therapy will be calculated as follows ([pretreatment corrected SUVmax - posttreatment corrected SUVmax]/pretreatment corrected SUVmax) x 100. Similar calculations will be performed for mean SUV, metabolic tumor volume, and total volume activity.

    An analysis of the quantitative data was recently performed for the 2 participants.

    Measured: Up to 2 years

Secondary outcomes (5)
  1. 18F-fluciclovine PET Imaging Response - SUVMax

    Will evaluate 18F-fluciclovine PET imaging response and its correlation with progression free survival defined by Prostate Cancer Working Group 2 criteria.

    Measured: Up to 2 years

  2. 18F-fluciclovine PET Imaging Response - SUVMean

    Will evaluate 18F-fluciclovine PET imaging response and its correlation with progression free survival defined by Prostate Cancer Working Group 2 criteria. SUVmean represents the average SUV value across a defined region of interest (ROI) in the tumor. The Measure Type is a number, that is dimensionless, because it is the average ratio of tissue activity concentration to the injected dose normalized by the patient's weight.

    Measured: Up to 2 years

  3. 18F-fluciclovine PET Imaging Response - Metabolic Tumor Volume

    Will evaluate 18F-fluciclovine PET imaging response and its correlation with progression free survival defined by Prostate Cancer Working Group 2 criteria.

    Measured: Up to 2 years

  4. Sites of Progressive Disease Development

    Will determine if sites of progressive disease develop at the initial/prior site (diagnostic site) of metastases or in newly developed sites at the time of metastatic progression.

    Measured: Up to 2 years

  5. Metabolic Response by 18F-fluciclovine PET With Target to Blood Pool Ratio (TBR)

    Will evaluate metabolic response by 18F-fluciclovine PET semi-quantitatively with TBR and correlate the findings with size changes as defined by conventional imaging and PSA response.

    Measured: Up to 2 years

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Computed Tomography, Fluciclovine F18 and Positron Emission Tomography in people with Metastatic Prostate Carcinoma and Stage IVB Prostate Cancer AJCC v8, run by M.D. Anderson Cancer Center 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 2 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 16 Jan 2025. 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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

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

Are results available for this study?

Yes. Results are posted in the registry (first posted 16 Jan 2025). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Metabolic Response by Fluciclovine F18 (18F-fluciclovine) Positron Emission Tomography (PET) With Standardized Uptake Values (SUV)" (time frame: Up to 2 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 16 Jan 2025.
