Radiation Therapy With RapidPlan Knowledge-based Planning vs Human-Driven Planning for Treatment of Prostate Cancer
What this study is about
This phase III trial compares the effects of radiation therapy using RapidPlan, trademark, knowledge-based planning to human-driven planning in treating patients with prostate cancer. Radiation therapy uses high energy x-rays, particles, or radioactive seeds to kill tumor cells and shrink tumors.
View original scientific description
This phase III trial compares the effects of radiation therapy using RapidPlan, trademark, knowledge-based planning to human-driven planning in treating patients with prostate cancer. Radiation therapy uses high energy x-rays, particles, or radioactive seeds to kill tumor cells and shrink tumors. Successful delivery of radiation requires planning to develop a treatment plan for how and where the radiation is to be delivered. RapidPlan is a knowledge-based treatment planning tool that automatically creates an optimal treatment plan based on identified targets and organs at risk for radiation exposure. Human-driven treatment planning by a dosimetrist, the current standard of care, requires significant resources and time and may vary within and among radiation centers. Giving radiation therapy with RapidPlan knowledge-based planning may have similar or less side effects compared to human-driven planning in treating patients with prostate cancer.
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
- Patients must be at least 18 years old
- Histologically confirmed prostate cancer
- Clinical or pathologic stages T1c-T3b, Nx or N0-1, M0-1 (American Joint Committee on Cancer \[AJCC\] criteria 8th edition \[Ed\])
- Planned definitive dose radiotherapy to the prostate or prostate bed
- Eastern Cooperative Oncology Group (ECOG) performance status 0-2 assessed within 90 days of enrollment
- Patients must sign Institutional Review Board (IRB) approved study specific informed consent
- Patients must complete all required pre-entry tests within the specified time frames
- Patients must be able to start treatment (radiation) within 180 days of study registration
- In case of confusion about the eligibility or ineligibility of an individual patient, the principal investigator (PI) can be used as the arbiter and a note to file will be added to the subject's regulatory binder to document outcome
Exclusion criteria
- Previous pelvic radiation \> 5 Gy
- Planned delivery of radiotherapy to pelvic lymph nodes
- Planned delivery of brachytherapy of the prostate
- Active rectal diverticulitis, Crohn's disease affecting the rectum, or ulcerative colitis (non-active diverticulitis and Crohn's disease not affecting the rectum are allowed)
- Prior hip replacement or penile implant
- Major medical, addictive, or psychiatric illness which in the investigator's opinion, will prevent the consent process, completion of the treatment and/or interfere with follow-up. (consent by legal authorized representative is not permitted for this study)
- Indwelling or intermittent urinary catheter use
Where
- Scottsdale, Arizona
- 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.
