A Pilot Study of Ultra-High Dose Rate (ConformalFLASH®), for Reirradiation of Carcinoma of the Head and Neck (C-FLASH-01)
2026年6月11日 更新者：IBA Proton Therapy, Inc.
This pilot study is designed to evaluate the feasibility of delivering ultra-high dose-rate conformal proton therapy (ConformalFLASH) in participants requiring re-irradiation for head and neck cancer who are not amenable to surgical resection.
ConformalFLASH treatment planning and delivery workflows are comparable to those of conventional Stereotactic Body Radiation Therapy (SBRT), a standard approach for re-irradiation in this population.
調査の概要
詳細な説明
C-FLASH-01 is a pilot study evaluating the feasibility of delivering ultra-high dose-rate conformal proton therapy (ConformalFLASH) to participants requiring re-irradiation for head and neck cancer who are not amenable to surgical resection.
Stereotactic Body Radiation Therapy (SBRT) re-irradiation is a standard approach that enables highly conformal dose delivery over a limited number of fractions.
ConformalFLASH is an investigational approach that applies SBRT principles using proton therapy delivered at ultra-high dose rates (≥ 40 Gray Relative Biological Effectiveness (GyRBE)/second), with the potential to reduce normal tissue toxicity while maintaining tumor control.
Participants will undergo treatment planning and delivery consistent with standard SBRT workflows.
Treatment consists of five fractions (8 GyRBE per fraction) delivered over approximately 1.5 to 2 weeks.
The primary objective is to assess the feasibility of delivering conformal proton SBRT at dose rates ≥ 40 GyRBE/second, along with evaluation of acute toxicity.
Secondary objectives include assessment of treatment delivery accuracy, late toxicity, clinical outcomes, and patient-reported quality of life.

Effect of the treatment on patient-reported quality of life, using the University of Washington Quality of Life Questionnaire (UW-QOL).The UW-QOL consists of domains based upon discrete ordinal responses regarding their past 7 days. Scoring is scaled so that a score of 0 represents the worst possible response, and a score of 100 represents the best possible response. The UW-QOL comprises 12 single-question domains, each between 3 and 6 response options. These options are scaled evenly from 0 (worst) to 100 (best), according to the hierarchy of response. Each domain is scored individually, and an overall composite score can be derived. In addition, patients are asked to choose up to 3 of these domains that they consider most important to them. The UW-QOL also includes 3 global questions, one about how patient feel relative to before they developed their cancer, one about their health-related QOL and one about their overall QOL. |
