Trial summary

Radiation therapy has been shown to be very effective at relieving pain caused by bone metastases. However, certain types of cancers such as prostate, breast, kidney, and melanoma can have resistance to radiation, making treatment less successful. Read more about this study

About this study

Radiation therapy has been shown to be very effective at relieving pain caused by bone metastases. However, certain types of cancers such as prostate, breast, kidney, and melanoma can have resistance to radiation, making treatment less successful. Stereotactic body radiotherapy (SBRT) is a newer form of focused treatment that gives higher doses of radiation without damage to surrounding organs. It often is used to help control and cure disease, but less commonly as a way to palliate and treat symptoms. This study is looking at using SBRT for the purposes of improving pain caused by bone metastases in prostate cancer, breast cancer, kidney cancer, and melanoma patients. It is theorized that the higher levels of radiation may be able to combat the resistance some tumour cells have to radiotherapy and provide improved pain response to treatment. The investigators are looking to show that SBRT has a role in helping this group of patients deal with painful bone lesions from their cancer without increasing side effects and toxicity from the radiation treatment.

Read the detailed description

Stereotactic body radiotherapy (SBRT) has shown promising early results in the management of bone metastases. However, there is a paucity of prospective data studying the use of SBRT for bone metastases originating from low alpha-beta tumors, with systematic reporting of changes in pain scores and analgesia use over time. The vast majority data looking at SBRT in bone lesions focuses on local control and survival, rather than more tangible outcomes in a palliative population including symptomatic control, durability of response, and patient reported quality of life; a component that is understudied in this group despite its tremendous value. Furthermore, SBRT for bone metastases has yet to become common practice given the limited evidence for its efficacy and uncertainty in regards to toxicity.

The current study proposes an investigation of the potential benefits of SBRT for symptomatic bone metastases in patients with prostate cancer, breast cancer, renal cell carcinoma, melanoma, and sarcoma. The investigators look to conduct a prospective cohort study that is adequately powered to analyse efficacy in alleviating pain from bone lesions and compare this to well-established rates in literature for conventionally fractionated palliative RT. Furthermore, this study will assess the tolerability of this modality, toxicity rates, and effect on quality of life. If the results show that SBRT has a significant benefit on this population, the goal would be to pursue a larger randomized trial to confirm the findings.

What participants receive

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

  • SBRTRadiation

    Patients will received a single fraction of 15-20 Gy to bone metastases causing pain. Planning and delivery will be conducted using a volumetric modulated arc therapy (VMAT) approach on the Varian TrueBeam platform. Patients will be CT simulated, with vac-lock immobilization. Use of 4-dimensional CT will be dependent on the area being treated. Daily image guidance will be performed using cone beam CT aligning to relevant bony anatomy.

Questions about this trial

What is this clinical trial studying?

A study testing SBRT in people with Bone Metastases and Prostate Cancer, run by Hamilton Health Sciences Corporation at 1 site in Canada.

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 3 inclusion and 11 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: status not confirmed, as of the sponsor's last update on 2 Aug 2021. 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 Canada. 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?

Results are not available in the source record.

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

Contact Stephan Tran, MD (905-387-9711 ext. 63123, transt@hhsc.ca), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Overall Pain Response (time frame: 3 months after treatment). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT04177056, which also lists 1 linked publication.

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 2 Aug 2021.
