Magnetic Resonance Guided Focused Ultrasound for Uterine Fibroids (PROMISe)

November 4, 2019 updated by: University of California, San Francisco

Magnetic Resonance-Guided Focused Ultrasound to Treat Uterine Fibroids: A Pilot Randomized, Placebo-Controlled Trial

This is a pilot randomized, blinded, placebo-controlled trial of a noninvasive, FDA approved treatment for uterine fibroids called MR Guided Focused Ultrasound (MRgFUS). Our hypothesis is that MRgFUS provides superior relief of fibroid symptoms compared with the placebo, a sham MRgFUS treatment. The investigators will recruit 20 premenopausal women with symptomatic uterine fibroids to participate in the trial. Participants will be randomly assigned in a 2:1 ratio to the active treatment arm (MRgFUS) versus the sham MRgFUS treatment. Participants will remain blinded to their group assignment for 3 months. After 3 months, participants will be told their treatment group and those assigned to the sham group will be offered complimentary MRgFUS if they desire it. Women will be excluded if they are inappropriate candidates for a 3 month delay in fibroid treatment, such as those with significant anemia. The investigators will assess the change from baseline to 1 and 3 months after treatment in fibroid symptoms, quality of life, fibroid volume measured by MRI, and hematocrit.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.
20

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 99 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Active Comparator: MR Guided Focused Ultrasound
Procedure: MR Guided Focused Ultrasound
This is an FDA approved noninvasive treatment for fibroids that uses highly focused ultrasound waves to damage fibroid tissue.
Placebo Comparator: Placebo MR Guided Focused Ultrasound
Procedure: Placebo MR Guided Focused Ultrasound
This is a placebo treatment that requires a participant to undergo identical procedures as those of the actual MR Guided Focused Ultrasound procedure, but higly focused ultrasound waves are not directed at the uterine fibroid.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Time Frame
Fibroid volume measured on MRI
Time Frame: Change from baseline prior to treatment until 3 months after treatment
Change from baseline prior to treatment until 3 months after treatment
Fibroid symptoms reported by participant
Time Frame: Change from baseline prior to treatment to 1 and 3 months after treatment
Change from baseline prior to treatment to 1 and 3 months after treatment
Red blood cell count (hematocrit)
Time Frame: Change from baseline prior to treatment and 3 months after treatment
Change from baseline prior to treatment and 3 months after treatment

Study Major Dates

Study Start

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
June 1, 2011

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
