Procedure: Abdominal or Laparoscopic Myomectomy
Procedure: Uterine Artery Embolization (UAE)

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: No masking
Primary Purpose: Treatment
Official Title: The Trust (Treatment Results of Uterine Sparing Technologies) Study

Primary Outcome Measures:
  • Compare direct cost of GFA compared to those of myomectomy and UAE [ Time Frame: 3 months post procedure ]
    To compare medical, surgical, and hospitalization costs (including procedural complication costs) of Global Fibroid Ablation (GFA) compared to those of Myomectomy and Uterine Artery Embolization (UAE)at 3 months post procedure.

  • Compare rates of acute and near-term serious complications to the acute and near-term treatment-related serious adverse events of pivotal study. [ Time Frame: 3 months post procedure ]
    Overall rates of acute (within 48 hours post procedure) and near-term (between 2 and 30 days post procedure) serious complications in all GFA subjects compared to the acute and near-term treatment-related serious adverse event rates in the pivotal study.

Secondary Outcome Measures:
  • Assess the comparative safety of the three treatment alternatives [ Time Frame: 60 Months ]
    Safety measures will be assessed by comparing the complication rate for all three alternatives (GFA, Myomectomy, UAE).

  • Assess factors that influence indirect costs of the three treatment alternatives [ Time Frame: 60 Months ]
    Compare incidence costs of post discharge procedure-related complications and re-interventions we well as indirect cost factors defined as days to return-to-work, return to normal activities of daily living, and cost of care up to 60 months post discharge.

  • Assess UFS-QoL pre-treatment to post treatment in all treatment groups [ Time Frame: 60 Months ]
    To compare fibroid symptom severity and quality of life scores at 3, 6, 12, 24, 36, 48, and 60 months post procedure as compared to baseline using the Uterine Fibroid Symptom and Health Related Quality of Life (UFS-QoL0 assessment tool.

  • Assess subjects menstrual bleeding using the MIQ [ Time Frame: 60 Months ]
    Compare subjects menstrual bleeding pre-treatment and up to 3, 6, 12, 24, 36, 48, and 60 months post treatment using the Menorrhagia Impact Questionnaire (MIQ).

  • Assess subject's satisfaction with her treatment [ Time Frame: 60 Months ]
    Compare subject's satisfaction and general health outcome at 3, 6, 12, 24, 36, 48, and 60 months post procedure as compared to baseline using the EQ-5D (a standardized instrument for use as a measure of health outcome).

Arms Assigned Interventions
Active Comparator: Woman Suitable for Myomectomy or GFA
This group will consist of women who desire uterine preservation. Women will be randomized 1:1 to GFA or Myomectomy (laparoscopic or abdominal).
Procedure: Global Fibroid Ablation (GFA)
GFA is being used for the treatment of symptomatic uterine fibroids
Other Name: GFA
Procedure: Abdominal or Laparoscopic Myomectomy
Myomectomy is a procedure in which uterine fibroids are surgically removed from the uterus.
Other Name: Myomectomy
Active Comparator: Woman Suitable for UAE or GFA
This group will consist of women who desire uterine preservation. Women will be randomized 1:1 to GFA or uterine artery embolization (UAE).
Procedure: Global Fibroid Ablation (GFA)
GFA is being used for the treatment of symptomatic uterine fibroids
Other Name: GFA
Procedure: Uterine Artery Embolization (UAE)
UAE is a minimally invasive surgical procedure used to treat uterine fibroids.
Other Name: UAE

Detailed Description:
Uterine fibroids are the most common pelvic neoplasms in women; they severely impact quality of life and are the leading indication for hysterectomy. Hysterectomy is the definitive treatment for myomas; however, many patients seek alternative uterine-sparing therapy and desire to conserve their fertility. Myomectomy is a much-reported surgical option for women with symptomatic fibroids and, until recently, the abdominal approach has been the approach of choice for most surgeons. Over time, patients have requested less invasive procedures and minimally invasive, laparoscopic options are becoming more popular among patients and their gynecologists. Standard surgical and interventional treatments for uterine fibroids are costly to society and to the health care system. New technologies such as GFA may offer a low-cost alternative to the standard treatments for symptomatic uterine fibroids in women who desire uterine conservation. This study seeks to evaluate those cost differences between three available uterine-sparing techniques and to explore the qualitative outcomes such as symptom severity, health related quality of life, and overall treatment effect.
