About this study

Official title: A Feasibility Study of Magnetic Resonance-guided High-Intensity Focused Ultrasound (MR-HIFU) Used for Mild Hyperthermia in Human Subjects

This study will help to elucidate the treatment sites in the extremities and pelvis for which MR-guided HIFU heating is feasible, which has the potential to be beneficial for patients with conditions at those sites (soft tissue sarcoma, cervical cancer, etc.). The investigators anticipate that successful completion of this study will lead to clinical trials in those feasible sites of interest to determine the safety and efficacy of administering therapeutic levels of heat for hyperthermia or other applications.

What participants receive

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

  • Magnetic Resonance-guided High-Intensity Focused UltrasoundDevice

    Also called MR-HIFU

    -Heating will not be performed in two areas of the body near each other (for example, not heating in two different places of the same thigh) to minimize the risk of overheating any one part of the subject's body. Heating a second target site is not mandatory, even if time allows, and the participant may refuse.

Study groups in NCT03007771
Study groupRoleWhat they receive
MR-HIFUExperimental* Philips 1.5T MRI scanner equipped with a Sonalleve V2 HIFU system will be used * Will be scanned in the MRI in 1 or more positions to the extremities and/or pelvis while aligned to the HIFU system. The HIFU device will then be used to apply sub-clinical levels (≤ 41°C) of heat to one or more small volumes. Regions will be heated to the desired temperature for variable short durations of time not exceeding 30 minutes. * After the session is complete, the patient will be removed from the MR-HIFU system and, following a 15-30-minute period of monitoring for any adverse events, allowed to leave. * Before the scan, after the scan and 5-10 days following the scan, participants will be asked to rate any pain, discomfort, in the area to be heated, as well as any anxiety or claustrophobia on a scale of 1-10 with 1 being minimal/none and 10 being extreme. The skin area to be treated will also be reviewed for any redness/discoloration.

What is being measured

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

  1. Feasibility of the MR-HIFU device as measured by whether an area can be heated to the designated temperature and held at that temperature for an appropriate time frame

    -Temperature in the participant will be monitored using MR thermometry with the MR scanner

    Measured: 1 day (2 hour timeframe)

  2. Feasibility of the MR-HIFU device as measured by whether an area can be heated while simultaneously maintaining patient comfort

    • Patient comfort will be measured by the Comfort Score. Before the scan, participants will be asked to rate any pain, discomfort, in the area to be heated, as well as any anxiety or claustrophobia on a scale of 1-10 with 1 being minimal/none and 10 being extreme. The skin area to be treated will also be reviewed for any redness/discoloration. After the scan, the same questions will be asked again of the subject.
    • Participants will be contacted by phone 5-10 days following participation in the study. Participants will be asked to describe any negative effects in the area heated since participation in the study, including pain, discomfort, and/or cosmetic changes (such as skin redness). Participants will be asked to score pain/discomfort on a scale of 1-10, with 1 being minimal/none and 10 being extreme.

    Measured: Up to 10 days

  3. Feasibility of the MR-HIFU device as measured by whether coupling can be maintained with the body area in the same position while having contact with the transducer for an appropriate time frame.

    -Patients' skin will be cooled using the MR-HIFU system's direct skin cooling device to minimize over heating of the skin, unless one or more gel pads are required to achieve proper coupling to the HIFU system. In order to ensure good contact with the surface of the HIFU interface, participants may be shaved or have other hair-removal products applied to limited regions of their body.

    Measured: 1 day (2 hour timeframe)

Secondary outcomes (3)
  1. Behavior of hyperthermia delivery as measured by the build-up of time until the different treatment cells can reach a desired uniform temperature

    --Temperature in the participant will be monitored using MR thermometry with the MR scanner

    Measured: 1 day (2 hour time frame)

  2. Behavior of hyperthermia delivery as measured by if the heating cell behavior is the same in healthy and tumor tissues

    --Temperature in the participant will be monitored using MR thermometry with the MR scanner

    Measured: 1 day (2 hour time frame)

  3. Behavior of hyperthermia delivery as measured by post-treatment heat diffusion behavior to anticipate any issues when heat is given at a clinically relevant level

    -Participants will be contacted by phone 5-10 days following participation in the study. Participants will be asked to describe any negative effects in the area heated since participation in the study, including pain, discomfort, and/or cosmetic changes (such as skin redness).

    Measured: Up to 10 days

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Magnetic Resonance-guided High-Intensity Focused Ultrasound in people with Healthy Participants and Pelvic Neoplasms, run by Washington University School of Medicine.

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 2 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 6 Oct 2017. Status can change between updates, so confirm with the study contact before making plans.

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.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

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?

Feasibility of the MR-HIFU device as measured by whether an area can be heated to the designated temperature and held at that temperature for an appropriate time frame (time frame: 1 day (2 hour timeframe)). The study lists 3 primary outcomes in all. 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 6 Oct 2017.
