Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
ARM B: Stereotactic Body Radiation Therapy (SBRT): 24Gy in 2 fractions delivered with a minimum of 1 and a maximum of 3 days gap days between fractions per treated site. If multiple sites are treated, these can be treated on the same day or alternate days and all sites must be treated within 14 calendar days.
Patients are required to attend a treatment planning session within 14 days of the start of treatment. The planning procedure will involve a computed-tomography (CT) scan as well as completion of a Magnetic Resonance Imaging (MRI) scan (if one hasn't been done within 6 weeks of starting treatment) and if the study doctor decides it is necessary, also a Positron Emission Tomography (PET) scan.
Treatment is expected to take around 45 minutes per treatment. The intervention will be prescribed by a radiation oncologist and administered by radiation therapists.
During treatment, imaging will be completed to ensure treatment is administered accurately.
All patients will complete quality of life and a pain and medication diary.

Comparator / control treatment
The comparator/control treatment for this study is the conventional radiotherapy (Arm A). The aim is to determine if interventional arm is superior to the comparator/control treatment.

A maximum of 1 fraction per day and all fractions to be delivered within 7 calendar days for a given site (or 8-10 days permitted only over public holiday periods). If multiple sites are treated, all sites must be treated within a 14-day calendar period.

Treatment is expected to take around 15 minutes per treatment. The treatment will be prescribed by a radiation oncologist and administered by radiation therapists.
During treatment, imaging will be completed to ensure treatment is administered accurately.
All patients will complete quality of life and a pain and medication diary.

Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Randomisation will be performed centrally by the sponsor via computer.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Randomisation will be performed with 1:1 allocation using random block sizes of 2 and 4 by an independent researcher, and stratified for radioresistant histologies (binary variable, where radioresistant histology will be coded ‘Yes’ if the patient has melanoma, renal cell carcinoma, colorectal or sarcoma, and ‘No’, if the patient has any other histological type) and site/centre. Where possible, project staff conducting the assessments will be blinded to participants’ allocation. The block sizes will not be disclosed, to ensure concealment.

Statistical methods / analysis
Conventional summary statistics will be presented to describe the characteristics of each trial arm. For all normally distributed variables, means and standard deviations will be used for reporting purposes. Medians and interquartile range will be used to summarise continuous non-normal variables, which had been determined to be non-normal using the Shapiro-Wilk test. Counts and percentages will be used to summarise categorical variables.
For the analysis of the primary endpoint, which is dichotomous, the difference in proportion of complete pain response between the two arms at 3 months post-initiation of treatment will be analysed using a logistic regression model, with treatment group included as the main effect. The effect estimate will be reported as an odds ratio with 95% confidence interval (CI). Analysis of the primary endpoint will be based on the intention to treat population. A p value < 0.05 will be considered statistically significant.
To investigate factors associated with the variability in response, univariable and multivariable binomial logistic regression will be used, with pre-specified variables that will be examined to include histological subtype, number of painful bony lesions, and baseline performance status.
For the secondary endpoints with binary outcomes, such as per lesion complete pain response at 3 months, complete pain response at 6 months (per patient) and partial pain response at 3 and 6 months (per lesion and per patient), a binary logistic regression model will be used to examine the difference between treatment groups. For secondary endpoints with continuous outcomes, such as quality of life scores, a linear regression model will be used. Effect estimates will be presented as mean difference (95%CI). For secondary endpoints with count outcomes, a Poisson regression model will be used. Effect estimates will be presented as incidence rate ratio (95% CI). For secondary endpoints with time-to-event outcomes, such as overall survival, a Cox proportional hazards model will be used. Effect estimates will be presented as hazard ratio (95% CI). For each model the treatment group will be included as a main effect, and the baseline value of the outcome variable will be included where appropriate.

Summary
Brief summary
The CONSOLE clinical trial aims to compare two schedules of radiotherapy in the treatment of painful cancer that has spread to bones not located in the spine.

Who is it for?
You may be eligible for this study if you are an adult over the age of 18 who has been diagnosed with cancer that has spread to your bones not located in the spine and is causing you pain.

Study details
Participants will be randomly assigned to one of two radiotherapy schedules as part of this study.
In Arm A, called the conventional treatment or current standard of care, participants will be either given in one (1) treatment on a single day or five (5) treatments over a period of a maximum of seven (7) calendar days for each area which is painful. If you are having more than one area treated, all areas must be completed within 14 calendar days. Each treatment will go for around 15 to 30 minutes.
.
In Arm B, called Sterotactic Body Radiotherapy (SBRT), participants will be given in two (2) treatments with a minimum of one (1) and a maximum of three (3) days gap between treatments for each area which is painful. If you are having more than one area treated, all areas must be completed within 14 calendar days. radiotherapy which is given in two treatments. Each treatment will take around 30 to 45 minutes.

Questionnaires and pain and medication diary will completed at the initial assessment, last day of treatment, 2 weeks after radiotherapy and at 3 and 6 months following the last treatment.
