Comparing a New PSMA Imaging Agent to MRI for Detecting Prostate Cancer, BEACON Trial
What this study is about
This early phase I trial evaluates whether a new imaging technique using flotufolastat F 18 (a type of prostate specific membrane antigen \[PSMA\] imaging agent) with positron emission tomography (PET)/computed tomography (CT) can be used to guide targeted prostate biopsies in men with prostate cancer.
View original scientific description
This early phase I trial evaluates whether a new imaging technique using flotufolastat F 18 (a type of prostate specific membrane antigen \[PSMA\] imaging agent) with positron emission tomography (PET)/computed tomography (CT) can be used to guide targeted prostate biopsies in men with prostate cancer. Flotufolastat F 18 is a radioactive imaging agent that binds to prostate tumor cells that express PSMA. This allows for visualization of PSMA-expressing tumor cells on imaging scans such as PET/CT. PET is an established imaging technique that utilizes small amounts of radioactivity attached to very minimal amounts of tracer, in the case of this research, flotufolastat F 18. Because prostate cancer takes up flotufolastat F 18, it can be seen with PET. CT utilizes X-rays that track the body from the outside. CT images provide an exact outline of organs and potential inflammatory tissue where it occurs in the body. The PET/CT scanner combines the PET and the CT scanners into a single device. A targeted prostate biopsy refers to using advanced imaging for guidance when taking samples (biopsies) of the prostate. This method can fuse (combine) PET/CT images with real-time ultrasound during a prostate biopsy. PSMA PET/CT scans have the potential for guiding prostate biopsies. Using image fusion technology, they can increase detection of prostate cancer by providing anatomical information and guidance during a prostate biopsy. Improved detection of prostate cancer using PSMA PET/CT guidance may better inform men and their clinicians about prostate cancer risk and management. This study attempts to determine how often prostate cancer is found when using PSMA PET/CT scan images during a biopsy versus the conventional magnetic resonance imaging-guidance.

Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- Men aged 18-90 at study enrollment
- Have at least one PI-RADS 3-5 lesion on MRI within the 12 months prior to enrollment
Exclusion criteria
- Contraindication to flotufolastat F 18 PET CT
- Contraindication to ultrasound-guided prostate biopsy
- Previous treatment of prostate cancer
- Unable to discontinue blood thinners for 7 days prior to biopsy
- Any investigational agents within 42 days prior to the day of the first dose
- Not able to understand and to follow study instructions and requirements. This also includes the inability to complete the study imaging and or biopsy procedures due to any reason (e.g., severe claustrophobia, inability to lie still for the entire imaging time, any condition that precludes raised arms position)

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
