Ultra-fractionated Radiotherapy for Rectal Cancer (NCT04677413)

Phase I Trial of Ultra-fractionated Adaptive Radiotherapy, Chemotherapy and Selective Omission of Surgery for Locally Advanced Rectal Cancer

🔵 Active, Not Recruiting Phase1 📋 Clinical Research Protocol Sponsor: University of Texas Southwestern Medical Center

🩺 Plain-English Summary (8th-Grade Level)

The rationale of this clinical trial is to assess the feasibility of selective non-operative management for locally advanced rectal cancer using dose-escalated ultra-fractionated short course radiation therapy interdigitated with chemotherapy. We believe delivering short course radiotherapy over a prolonged interval, at escalated doses and with concurrent chemotherapy may be feasible and allow for improved clinical response.

Who can join: To join this study, participants generally need to meet the listed inclusion criteria (16 items) and avoid the listed exclusions (6 items).

Location: UT Southwestern Medical Center — Dallas, Texas
