About this study

The study hypotheses is that the proportion of patients experiencing clinically significant pain relief will be at least 30% greater than the proportion experiencing worsening pain.

Read the detailed description

As part of the PMA # P110039 review process and approval, InSightec was requested to conduct a post-approval study. Patients will be treated following the approved commercial treatment guidelines.

For this study, participating sites will use the ExAblate device for the administration of the ExAblate treatment. This study will be performed on either 1.5T or 3T MR scanners.

For this study, a total of 70 patients meeting the approved commercial guidelines will be enrolled and treated with the ExAblate system at from 7 to 10 sites. The proportion of responders is expected to be at least 30% greater than the proportion of subjects experiencing pain progression (i.e., 60% vs. 30%). Additionally, at the 3 month visit, an analysis of both the safety and efficacy profiles will be compared to the original PMA pivotal study group.

What is being measured

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

  1. Proportion of Responders

    The statistical hypothesis is that the proportion of responders will be significantly greater than the proportion of subjects experiencing pain progression (worsened pain or increased pain medications usage). Using the Numerical Rating Score (NRS) for pain (0 being no pain and 10 being worst imaginable pain), subjects were rated as a Responder or as having Pain Progression. A responder is defined as a subject with a reduction in NRS worst score from baseline of two (2) or more points, and no increase in pain medication use. Pain Progression was increased pain of two (2) or more points.

    Measured: Three months post treatment

Questions about this trial

What is this clinical trial studying?

A study testing ExAblate MRgFUS in people with Bone Metastasis, run by InSightec at 9 sites in United States.

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 20 inclusion and 31 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: finished, as of the sponsor's last update on 7 Apr 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 9 sites in United States. 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?

Yes. Results are posted in the registry (first posted 7 Apr 2023). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Proportion of Responders (time frame: Three months post treatment). 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 7 Apr 2023.
