Clinical Trial Summary

The purpose of the study is to investigate effectiveness of stereotactic body radiotherapy in patients with bone metastatic disease.

Description:

Rationale: Bone metastases are a frequent distant manifestation of solid tumours, and many bone metastases are located in the spine. These patients mostly present with severe (back) pain which reduces quality of life. The primary treatment for pain management is a single-fraction low dose external beam radiation therapy (EBRT), effective in achieving pain reduction in around 60% of patients, of whom 0-23% experience complete pain response. Recently, there is growing evidence that Stereotactic Body Radiotherapy (SBRT) achieves a much higher pain response due to the higher dose administered. In retrospective and a few prospective case series, SBRT for spinal, and also non-spinal metastases has been demonstrated to be safe, and efficacious. However, no randomized controlled trials have been performed.

Objective: To study whether the pain response after three months in patients with osseous metastatic disease increases after SBRT in comparison to low dose EBRT.

Study design: Randomized controlled trial, the VERTICAL study, nested within the PRESENT cohort.

Study population: Eligible patients are MRI-compatible patients with radiographic evidence of bone metastases at the radiotherapy department. Fifty-five patients are recruited in both control and intervention arm.

Intervention: Patients will undergo MRI-based, cone beam CT-guided SBRT and will receive a single dose of 18 Gray (Gy) on the visible metastasis, and 8 Gy on the bony compartment containing the metastasis (e.g. the affected vertebra or pedicle).

Main study parameters/endpoints: The primary endpoint is pain control at three months after radiotherapy. Secondary outcomes are, among others, the occurrence of vertebral compression fracture (VCF) and radiation-induced myelopathy, local tumour control and evaluation of quality of life.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Complete or partial pain response after radiation, defined according to the International Bone Metastases Consensus Endpoints for Clinical Trials.	The primary endpoint of this study is complete or partial pain response after SBRT or EBRT after three months. Complete and partial response, but also possible pain progression or indeterminate response, will be defined according to the International Bone Metastases Consensus Endpoints for Clinical Trials.	3 months
Secondary	Health-Related Quality of Life	Self reported quality of life as measured by the Brief Pain Inventory, European Organization for Research and Treatment of Cancer (EORTC) quality of life questionnaire (QLQ) C15-PAL, and EORTC QLQ BM22	at 2, 4, 6, 8 weeks, 3 and 6 months, then every 6 months
Secondary	Progression free survival	Progression free survival is defined as time between treatment and first sign of progression of disease	up to 3 years
Secondary	Overall survival	Overall survival is defined as time between treatment and death from any cause	up to 3 years
Secondary	Occurrence or progression of vertebral compression fracture (VCF)	VCF is defined as new endplate fracture or collapse deformity as compared with before SBRT or EBRT	up to 12 months
Secondary	Occurrence of radiation-induced myelopathy	Radiation-induced myelopathy is defined as a diagnosis of exclusion and defined as neurological signs and symptoms consistent with radiation damage in the form of necrosis to the segment of the spinal cord irradiated, without MRI evidence of recurrent or progressive tumour affecting the spinal cord.	up to 12 months
Secondary	Duration of pain relief	Duration of pain relief as measured by the Brief Pain Inventory	at 2, 4, 6, 8 weeks, 3 and 6 months
Secondary	Determination of rapidity of pain relief	Rapidity of pain relief as measured by the Brief Pain Inventory	at 2, 4, 6, 8 weeks, 3 and 6 months
