About this study

Official title: China Clinical Trial for Therapeutic MRI-guided High Intensity Focused Ultrasound Ablation of Uterine Fibroids

The purpose of this study is to demonstrate safety and effectiveness of the Philips Sonalleve Magnetic Resonance Imaging-guided High Intensity Focused Ultrasound (MR-HIFU) for treatment of uterine fibroids in a Chinese population.

Read the detailed description

This study is to confirm the safety and effectiveness of Magnetic Resonance Imaging-guided High Intensity Focused Ultrasound (MR-HIFU) in ablating uterine tissue associated with symptomatic leiomyomas. The importance of this therapy is that it offers a non-invasive, uterine sparing procedure for the treatment of uterine fibroids in pre- and peri- menopausal women.

MR-HIFU uses ultrasound to heat and thermally ablate fibroid tissue. The MRI system identifies the ultrasound path and monitors heat rise in the fibroid tissue. The goal of the study is to show treatment safety and effectiveness of the Philips Sonalleve MR-HIFU device for uterine fibroids marketing approval in the Chinese market. MR-HIFU will be performed in 100 patients who pass inclusion/exclusion criteria. Safety, quality of life, and imaging endpoints will be evaluated in all study patients at baseline and at 6 months post-treatment. All patients will be followed up for 12 months post-treatment for safety.

What is being measured

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

  1. Change in fibroid volume

    Proportion of patients with treated fibroid volume at 6 months after treatment reduced to 90% or less of treated fibroid volume at baseline (before MR-HIFU treatment)

    Measured: At baseline and at 6 months after treatment

  2. Adverse Events

    Number of Adverse Events reported as resulting from MR-HIFU treatment

    Measured: Within 6 months after treatment

Questions about this trial

What is this clinical trial studying?

A study testing MR-HIFU uterine fibroid treatment in people with Uterine Fibroids, run by Philips Healthcare at 2 sites in China.

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 13 inclusion and 13 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 22 Oct 2015. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in China. 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 is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Change in fibroid volume (time frame: At baseline and at 6 months after treatment). The study lists 2 primary outcomes in all. 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 NCT01588899, 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 22 Oct 2015.
