Brief Summary

The purpose of this study is to evaluate the safety and effectiveness of Embozene Microspheres compared with Embosphere Microspheres for the treatment of symptomatic uterine fibroids. A total of 118 patents with symptomatic uterine fibroids will be enrolled at 6 sites. Symptom severity, health-related quality of life, and the appearance of the fibroids will be assessed prior to treatment. Patients will then undergo the uterine fibroid embolization procedure with either Embosphere Microspheres or Embozene Microspheres, which will be randomly assigned. Clinical outcomes will be assessed 1 month, 3 months, 6 months and 12 months after the procedure, and imaging outcomes will be obtained 3 months after the procedure.

Detailed Description

The uterine fibroid embolization (UFE) procedure is an accepted, minimally invasive treatment option for patients with symptomatic uterine fibroids. Studies evaluating the outcomes after this procedure have established that the use of polyvinyl alcohol particles and Embosphere Microspheres is associated with best clinical and imaging outcomes. Embozene Microspheres represent a new embolic agent that is being evaluated for use for the treatment of symptomatic fibroids. The purpose of this study is to evaluate the safety and effectiveness of Embozene Microspheres compared with Embosphere Microspheres for the treatment of symptomatic uterine fibroids.

A total of 118 patents with symptomatic uterine fibroids will be enrolled at 6 sites. A questionnaire designed to assess symptom severity and health-related quality of life in patients will be administered to patients at the time of enrollment. In addition, a contrast-enhanced magnetic resonance imaging (MRI) examination will be performed to confirm the diagnosis of fibroids. Patients will then undergo the uterine fibroid embolization procedure. The embolic agent used for the procedure (Embosphere Microspheres or Embozene Microspheres) will be randomly assigned. Patients will be seen 1 month, 3 months, and 6 months and contacted 12 months after the procedure so that the same questionnaire can be used to assess clinical outcomes. In addition, an MRI will be performed 3 months after the procedure to determine the imaging response to treatment.

Study Groups

Embozene Microspheres

Patients will undergo the uterine fibroid embolization procedure with Embozene Microspheres as the embolic agent.

Group Type: EXPERIMENTAL

Uterine Fibroid Embolization

Intervention Type: PROCEDURE

This procedure involves the administration of the study device into the uterine arteries to block the flow of blood in these vessels. This deprives fibroid tumors within the uterus of their blood flow, which can cause the tumors to die. This in turn can lead to the relief of symptoms associated with fibroids.

Embosphere Microspheres

Patients will undergo the uterine fibroid embolization procedure with Embosphere Microspheres as the embolic agent.

Group Type: ACTIVE_COMPARATOR

Uterine Fibroid Embolization

Intervention Type: PROCEDURE

This procedure involves the administration of the study device into the uterine arteries to block the flow of blood in these vessels. This deprives fibroid tumors within the uterus of their blood flow, which can cause the tumors to die. This in turn can lead to the relief of symptoms associated with fibroids.

Eligibility Criteria

Inclusion Criteria

1. She is able to provide informed consent and sign the Institutional Review Board approved informed consent form.

2. She is pre-menopausal and 30-50 years of age at the time of enrollment.

3. She is not actively attempting to become pregnant for a minimum of 1 year after UFE, or practicing abstinence and willing to continue for a minimum of 1 year after UFE, or is surgically sterile.

4. She is suffering from clinically significant symptoms attributed to the presence of uterine fibroids including abnormal menstrual bleeding and/or bulk-related symptoms including pelvic pain/discomfort, abdominal distension, urinary symptoms (including but not limited to increased urinary frequency or urinary hesitancy), and/or dyspareunia.

Exclusion Criteria

1. She has a history of pelvic malignancy.

2. She is pregnant or intends to become pregnant within 12 months of the planned UFE procedure.

3. She has had an abnormal PAP smear (anything other than normal or ASCUS - Atypical Squamous Cells of Unknown Significance) within 12 months of the planned UFE procedure.

4. She has a coexisting condition that might explain the presenting symptoms (including but not limited to adenomyosis, endometrial hyperplasia, endometriosis, and complex ovarian cysts).

5. She has evidence of current or recent pelvic inflammatory disease or uterine infection.

6. She has another serious medical condition that might preclude full participation in the study to the desired endpoint (e.g., uncontrolled diabetes, malignancy, chronic obstructive pulmonary disease, myocardial infarction, congestive heart failure, etc.)

7. She has a severe contrast allergy or renal insufficiency that would represent a contraindication to the administration of iodine-based or gadolinium-based contrast agents.

8. She has a contraindication to magnetic resonance imaging (MRI).

9. She has one or more MRI findings including a uterine size >20 cm in greatest length, a dominant fibroid with a greatest diameter >12 cm, an intracavitary submucosal fibroid, or non enhancing dominant fibroids.

10. In the judgment of the investigator, she is unable or unlikely to be able to comply with the study procedures and requirements.
