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
- Disease: Prostate cancer
- Treatment site:
- Prostate or prostate and seminal vesicle
- No regional lymph node is involved
- Patient's body weight: Patient's body weight is less than 350 lbs to consider the total weight limit that the ProteusONE treatment table and the robotic arm can operate
- Treatment volume size: maximum size less than 15 x 15 cm in a cross-section and a thickness less than 20 cm to consider 2D transducer matrix size
- Provision to sign the consent form and understand the non-invasiveness of iRAI
- Patient agreement on tolerance on placing a water bag to acquire iRAI during treatment
- Treatment modality: Proton radiation therapy with UFHPTI's ProteusONE gantry using PBS
Exclusion criteria
- A patient who would not be tolerable or will feel nervous about being touched on the skin with a water bag
- A patient with a significant medical implant or hardware in the treatment area
Where
- Jacksonville, Florida
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.
