Comparing RapidPlan and human-driven planning for prostate cancer radiation therapy

Official title: Randomized Phase III Trial of Rapid-Plan Knowledge-Based Planning vs. Human-Driven Planning for Prostate Cancer Radiotherapy

Run by Mayo Clinic · NCT06625034 · Data updated 2026-11-12

This study is testing if a new computer-based tool for planning radiation therapy can work as well as traditional methods for prostate cancer patients while causing fewer side effects.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are adult males aged 18 and older with histologically confirmed prostate cancer at specific clinical stages.

Probably not a fit

Patients with a history of previous pelvic radiation exceeding 5 Gy may not benefit from this study.

What this trial studies

This phase III trial evaluates the effectiveness of RapidPlan, a knowledge-based planning tool, against traditional human-driven planning in delivering radiation therapy to prostate cancer patients. The study aims to determine if RapidPlan can achieve similar or fewer adverse effects related to genitourinary and gastrointestinal systems compared to the standard method. Patients will be randomized into two groups, one receiving human-driven planning and the other using RapidPlan, with follow-up assessments at 3 and 12 months post-treatment. The trial also explores quality of life and dose-volume constraints associated with each planning method.

Why it matters

Potential benefit: If successful, this study could lead to more efficient and potentially safer radiation therapy planning for prostate cancer patients.

How similar studies have gone: While knowledge-based planning is gaining traction, this specific comparison of RapidPlan to human-driven planning is relatively novel.

Inclusion Criteria:

* Patients must be at least 18 years old
* Histologically confirmed prostate cancer

* 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

* 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)
