Comparison of Adaptive Dose Painting by Numbers With Standard Radiotherapy for Head and Neck Cancer. (C-ART-2)

December 13, 2022 updated by: University Hospital, Ghent

A Two-arm Phase II Randomized Study, Comparing Adaptive Biological Imaging - Voxel Intensity - Based Radiotherapy (Adaptive Dose Escalation) Versus Standard Radiotherapy for Head and Neck Cancer.

The investigators hypothesize that treatment adaptation to biological and anatomical changes, occurring during treatment, can increase the chance of cure at minimized or equal radiation-induced toxicity in head and neck cancer patients. This trial compares standard intensity-modulated radiotherapy (IMRT), using only pre-treatment planning 18F-2-fluoro-2-deoxy-D-glucose positron emission tomography to adaptive 18F-2-fluoro-2-deoxy-D-glucose positron emission tomography voxel intensity based IMRT or volumetric-modulated arc therapy (VMAT) using repetitive per-treatment planning 18F-2-fluoro-2-deoxy-D-glucose positron emission tomography for head and neck cancer.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

14 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

What is the study measuring?

Primary Outcome Measures
