The primary objective of this study is to establish the effectiveness and confirm the safety of the VizAblate System in ablating symptomatic uterine fibroids.

Condition Intervention
Uterine Fibroids
Device: VizAblate System

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Treatment
Official Title: Symptom Effectiveness Study of VizAblate™ Intrauterine Ultrasound-Guided RF Ablation (IUUSgRFA) in the Ablation of Uterine Fibroids

Further study details as provided by Gynesonics:

Primary Outcome Measures:
  • Mean percentage change in target fibroid perfused volume [ Time Frame: 3 months ]

Secondary Outcome Measures:
  • Number of adverse events [ Time Frame: procedure through 12 mo ]
    Procedure safety will be assessed by recording all adverse events that occur on the day of the procedure. Longer-term safety will be assessed by recording at each follow-up visit any untoward medical occurrence since baseline. Each adverse event will be assessed for severity and relationship to study device.

  • Percentage reduction in Menstrual Pictogram score [ Time Frame: baseline through 12 months ]
  • Percentage reduction in the Symptom Severity Subscale (SSS) of the Uterine Fibroid Symptom and Quality of Life (UFS-QOL) questionnaire [ Time Frame: baseline through 12 months ]
  • Rate of surgical reintervention for menorrhagia [ Time Frame: through 12 months ]
  • Return to normal daily activity [ Time Frame: 2 weeks or until returned to normal activity ]

Other Outcome Measures:
  • Subject satisfaction [ Time Frame: 3 month, 6 month, 12 months ]
  • Anesthesia regimen [ Time Frame: Day of procedure ]
  • System ease of use [ Time Frame: End of study ]
  • Subject pain and tolerance of procedure [ Time Frame: Day of procedure ]
  • HRQL sub scale of Uterine Fibroid Symptom Quality of Life (UFS-QOL) questionnaire [ Time Frame: 3 month, 6 month, 12 months ]
  • EuroQOL EQ-5D [ Time Frame: 3 month, 6 month, 12 month ]
  • Length of Stay [ Time Frame: Day of procedure ]
  • Nonsurgical reintervention for menorrhagia [ Time Frame: 30 day, 3 month, 6 month, 12 month ]

Enrollment: 51
Study Start Date: January 2011
Study Completion Date: March 2014
Primary Completion Date: March 2014 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: VizAblate treatment
VizAblate System: subject acts as her own control
Device: VizAblate System
VizAblate enables a minimally invasive procedure to visualize, target, and ablate uterine fibroids using intrauterine ultrasound and radiofrequency (RF) energy.
