About this study

Official title: Efficacy of Magnetic Resonance-guided High Intensity Focused Ultrasound for the Ablation of Breast Cancer: Correlation Between MRI and Histology. Single-Center, Single-Arm, Non-Randomized Trial

The purpose of the study is to evaluate the efficacy of a dedicated Magnetic Resonance guided High Intensity Focused Ultrasound (MR-HIFU) unit in ablating breast cancer by comparing MR imaging and pathologic specimen after resection.

Single-center, single-arm, non-randomized trial

Read the detailed description

The dedicated MR-HIFU unit has been shown to be safe and feasible to ablate breast tissue.

The planned study should address the possibility to completely ablate breast cancer with the dedicated breast MR-HIFU unit. The result of the MR-HIFU therapy should be monitored by imaging (contrast enhanced MRI) as well as with histopathological correlation after surgery.

The patient population would consist of female patients with proven breast cancer scheduled for surgical lumpectomy or mastectomy.

The idea is to evaluate a minimal invasive method to treat breast cancer as a potential alternative to surgical resection in the future

Being tested

What participants receive

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

  • Philips Sonalleve® MR-HIFU Breast Therapy SystemDevice

    The breast tumor lesion of qualified study patients will be treated with MR-HIFU under procedural sedation with Propofol and Ketamine.

Study groupRoleWhat they receive
MR-HIFU treatmentExperimentalPatients with breast cancer and scheduled surgical resection (lumpectomy or mastectomy) will be treated with Philips Sonalleve® MR-HIFU Breast Therapy System prior to surgery in a treat\& resect model
Receives: Device: Philips Sonalleve® MR-HIFU Breast Therapy System

What is being measured

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

  1. Accuracy of MRI as Method for Assessment of Quantitative Treatment Success (Correlation With Results of the Histopathological Analysis Performed as Reference Method)

    Quantitative assessment: Correlation between MRI and histopathology results (volume of necrosis)

    Measured: Day 14

Secondary outcomes (1)
  1. Assessment of Treatment Efficacy

    Effective treatment is defined as complete necrosis (100%) of targeted tumor including safety margin (>1mm) (histopathological analysis).

    Safety margin: measurement of smallest margin on histology and measurement of smallest margin on MRI. Parameter: Percentage of necrosis including safety margin

    Measured: Day 14

Questions about this trial

What is this clinical trial studying?

A study testing Philips Sonalleve® MR-HIFU Breast Therapy System in people with Breast Cancer, Invasive Ductal, run by Kantonsspital Winterthur KSW at 1 site in Switzerland.

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 8 inclusion and 14 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: stopped early, as of the sponsor's last update on 22 Oct 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 Switzerland. 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 22 Oct 2021). 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?

Accuracy of MRI as Method for Assessment of Quantitative Treatment Success (Correlation With Results of the Histopathological Analysis Performed as Reference Method) (time frame: Day 14). 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 22 Oct 2021.
