Randomized Phase III Trial of Rapid-Plan Knowledge-Based Planning vs. Human-Driven Planning for Prostate Cancer Radiotherapy
Mayo Clinic
Summary
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.
Description
PRIMARY OBJECTIVE: I. To determine if RapidPlan knowledge-based planning is non-inferior to human-driven planning regarding treatment-related rates of grade 3 or higher genitourinary (GU) and gastrointestinal (GI) adverse events at 3 months post-radiotherapy for prostate cancer. EXPLORATORY OBJECTIVES: I. After completion of radiation therapy, determine the incidence of: Ia. Grade 2 or greater GU and GI toxicity at 3 months (Common Terminology Criteria for Adverse Events \[CTCAE\] version 5); Ib. Quality of life 3 months post-radiotherapy; Ic. Rate of achieving dose-volume constraints. II.…
