About this study
Official title: Comparing Options for Management: Patient Centered Results for Uterine Fibroids
The overall goal of this project is to better enable patients with uterine fibroids (UF) to make informed decisions about treatment options by leveraging the highest possible evidence of healthcare quality. The foundation of this project will be a multi-site, prospective registry of a diverse group of women who have undergone either medical or surgical treatment for UF.
Specifically, the investigators are interested in: comparing management options for symptom relief; comparing management options for preserving reproductive function; and comparing effectiveness among different subpopulations, including consideration of patient needs and preferences of treatment options.
Read the detailed description
COMPARE UF will enroll approximately 10,000 subjects across 9 clinical enrolling centers in the US. We anticipate recruitment to last approximately 24 months. Sites will consent interested patients and have them complete a patient contact information form to be used to contact the patient for telephone interviews. Following informed consent, the site will collect clinical information and several patient-reported outcomes scales, including the Uterine Fibroid Symptom Quality of Life Questionnaire (UFS-QOL), the Menopausal Rating Scale, and the EQ-5D, a standardized measure of general health outcomes.
In year 01 of this study, among patients receiving a procedure to treat their UF, 1000 will be asked to provide two blood samples: the first at time of enrollment (before the procedure) and the second at 12 months after the procedure. Samples will be evaluated for ovarian reserve via a blood assay measurement of anti-mullerian hormone.
Additionally, for patients who have a procedure to treat their UF, they will have a routine clinic follow-up visit, sometime between 6 - 12 weeks post procedure. Additional clinical data will be collected at this time.
For patients who are treated medically, there will be no further study-related clinic visits. Follow-up will occur exclusively by telephone.
All consented patients will complete telephone interviews at approximately 12, 24, and 36 months following the initial procedure. It is anticipated that patients enrolled during the first study year will complete a maximum of three years of follow-up. However, if additional funds become available, the investigators plan to extend the follow-up of enrolled patients to five years.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
hysterectomyProcedure or surgery
surgical removal of the uterus
Uterine arterial embolizationProcedure or surgery
Also called UAE
In uterine artery embolization, doctor uses a slender, flexible tube (catheter) to inject small particles (embolic agents) into the uterine arteries, which supply blood to your fibroids and uterus.the embolic agents are injected into these fibroid blood vessels. The goal is to block the fibroid vessels, starving the fibroids and causing them to shrink and die.
myomectomyProcedure or surgery
surgical procedure to remove uterine fibroids, but does not remove uterus
Medical TherapyDrug
treatment of uterine fibroids with only medications, no procedure or surgery is used
endometrial ablationProcedure or surgery
Also called NovaSure, Her Option, HydroTherm
surgical procedure that destroys uterine lining via a telescope placed inside the uterus
magnetic resonance guided focused ultrasoundProcedure or surgery
Also called MRgFUS, ExAblate; Sonalleve
procedure that destroys fibroids while inside an MRI machine
radiofrequency ablationProcedure or surgery
Also called Accessa
procedure that uses heat to destroy uterine fibroids
| Study group | Role | What they receive |
|---|---|---|
| Medical | Patients who receive medical therapy only for treatment of their uterine fibroids Receives: Drug: Medical Therapy | |
| Procedure | Patients who have a hysterectomy, myomectomy, uterine arterial embolization, endometrial ablation, radiofrequency ablation, or magnetic resonance guided focused ultrasound to treat their UF. Receives: Procedure: hysterectomy; Procedure: Uterine arterial embolization; Procedure: myomectomy; Procedure: endometrial ablation; Procedure: magnetic resonance guided focused ultrasound; Procedure: radiofrequency ablation |
What is being measured
The primary outcome is the main question the study is designed to answer.

Measured: 12, 24, 36 months
Secondary outcomes (1)
change in preservation reproductive function (patient interview)
ability of a woman after receiving treatment for uterine fibroids can conceive and deliver a healthy baby
Measured: 12, 24, 36 months

Questions about this trial
What is this clinical trial studying?
An observational study of Fibroids, Uterine, run by Duke University 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 2 inclusion and 3 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 18 Nov 2020. 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?
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 symptom relief (patient interview) (time frame: 12, 24, 36 months). 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 NCT02260752, which also lists 8 linked publications.
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 18 Nov 2020.
