HOT II clinical trial
HOT II is a randomised double-blind controlled Phase III trial of hyperbaric oxygen therapy in patients suffering long-term adverse effects of radiotherapy for pelvic cancer. It is currently recruiting.
Aim of the trial
The HOT II trial aims to test the clinical benefits of hyperbaric oxygen therapy in reducing dysfunction in patients developing iatrogenic gastrointestinal symptoms as a result of previous radical pelvic radiotherapy for cancer, which was completed at least one year previously.
75 patients eligible for the study will be randomised by a hyperbaric technician using a 2:1 ratio of treatment:control.
The trial is funded by Cancer Research UK and the Department of Health, and sponsored by The Institute of Cancer Research and The Royal Marsden. It is being led by Dr Jervoise Andreyev, Consultant Gastroenterologist in Pelvic Radiation Disease, and Professor John Yarnold, Consultant Clinical Oncologist.
