Study information
Scientific title
Acronym
PROFIT (PROstate Fractionated Irradiation Trial)
Study hypothesis
To determine whether a 4-week course of hypofractionated radiotherapy is as safe and effective as a standard 8-week course of radiotherapy for treatment of intermediate risk localised prostate cancer.
On 12/11/2008 this record was updated to include an amendment to the exclusion criteria and a change of sponsor. The initial sponsor was McMaster University (Canada) as this was where the Ontario Clinical Oncology Group (OCOG) was initially based, but this has now moved to the Henderson Research Centre. Please also note that at this time, Australia was added to the trial countries of recruitment.
