About this study

Official title: Stereotactic Body Radiotherapy Followed by Surgical Stabilization for Patients With Unstable Spinal Metastases: Cohort Study According to the IDEAL Recommendations

The aim of this study is to assess pain response after combining stereotactic body radiotherapy (SBRT) and pedicle screw fixation in a 48-hour window for the treatment of painful unstable metastases of the thoracic and/or lumbar spine.

Read the detailed description

Rationale Sixty-five percent of cancer patients with terminal illness have bone metastases, with debilitating pain often as the severe consequence. The spine is the most common location for bone metastases. Standard treatment of unstable vertebral metastases consists of stabilizing surgery, followed by external beam radiotherapy after two weeks. Although this approach is effective in 60-70% of patients, it is has several downsides. Firstly, because of the two weeks interval between surgery and external beam radiotherapy, necessary for sufficient wound healing, it takes time before radiotherapy-induced pain relief is achieved. Moreover, the surgical implants used cause scatter artifacts on planning computed tomography images which prohibits high-resolution imaging and accurate targeting of the lesion. Multiple hospital visits (ranging from 1 to 10) are needed for administration of external beam irradiation, and in about 30-40% of patients no adequate pain response is achieved. An alternative treatment strategy, which would lead to faster pain relief in a higher proportion of patients with less hospital visits, would be highly desirable from the patient's perspective. Secondly, this strategy delays the start of systemic therapy.

Objective The main outcome of this study is pain response 4 weeks after start of the treatment.

Study design Prospective cohort study nested within the PRESENT cohort being a phase 2b study according to the IDEAL recommendations

Study population All patients, male and female, with impending spinal instability requiring surgical intervention and radiotherapy at the University Medical Center Utrecht

Intervention The combined treatment of stereotactic body radiotherapy and pedicle screw fixation in a 24 to 48-hour window for the treatment of painful unstable metastases of the cervical, thoracic and/or lumbar spine.

Main study parameters/endpoints The main outcome of this study is pain response after 4 weeks

Nature and extent of the burden and risks associated with participation, benefit and group relatedness In the preceding BLEND First-in-man study, the investigators have observed no Serious Adverse Events after a median follow-up of 13 months demonstrating the safety and feasibility of this approach.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • SBRT followed by surgical stabilization within 24-48 hoursOther

    In a first step, patients will undergo SBRT with active sparing of the surgical site. Patients will receive high dose, single to few fractions radiotherapy consisting of a boost to the metastases exclusively. The bony compartment containing the metastatic lesion will receive an elective dose in order to treat subclinical disease. Treatment planning is performed on the pre-treatment CT and MRI data in radiotherapy position that are mutually registered to yield information on all relevant structures for planning. Dose constraints are set for the organ at risks based on institution specific guidelines. All patients will be treated with on online position verification protocol based on institution specific guidelines. Hereafter, surgical intervention will be performed to the standard of care.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Pain response

    Pain response is defined as a decrease in initial worst pain score by at least 2 points on a Numeric Rating Scale (NRS) of 10 at the treated site, without increase in analgesic use, or an analgesic decrease of at least 25% without an increase in pain score

    Measured: 4 weeks

Secondary outcomes (6)
  1. Duration of pain relief

    Duration of pain relief, as measured by the Brief Pain Inventory (BPI)

    Measured: Through hospital stay, an average of 3 days

  2. Length of hospital stay

    Length of hospital stay in days

    Measured: Through hospital stay, an average of 3 days

  3. 30-day mortality

    Mortality after 30 days

    Measured: 30 days

  4. Neurological status

    American Spinal Injury Association (ASIA) scale as measured by physical examination of neurologists or trained ASIA physician

    Measured: Through hospital stay, an average of 3 days

  5. Neurological deterioration

    Defined as a deterioration on the American Spinal Injury Association (ASIA) scale of more than one level

    Measured: Through hospital stay, an average of 3 days

  6. Adverse events

    Adverse events will be scored using a SAVES form

    Measured: Through hospital stay, an average of 3 days

Questions about this trial

What is this clinical trial studying?

A study testing SBRT followed by surgical stabilization within 24-48 hours in people with Spinal Neoplasms and Neoplasm Metastasis, run by UMC Utrecht at 1 site in Netherlands.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 7 inclusion and 9 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: withdrawn, as of the sponsor's last update on 18 May 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Netherlands. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study was withdrawn before enrolling participants, so there are no results.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Pain response (time frame: 4 weeks). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 18 May 2023.
