HOME Study: Hysteroscopic Office Myomectomy Evaluation (HOME)

A Hysteroscopic Office Myomectomy Evaluation Using the MyoSure Tissue Removal System for the Removal of Uterine Fibroids and Polyps in the Treatment of Abnormal Uterine Bleeding (AUB)

The purpose of this study is to demonstrate safety and effectiveness of the MyoSure Tissue Removal System when used by community gynecologists in an office setting for the treatment of patients with symptomatic intrauterine polyps and submucosal fibroids.

Study Overview

• Status: Completed
• Conditions: Polyps; Uterine Fibroids
• Intervention / Treatment: Device: Myomectomy

Detailed Description

Approximately one hundred subjects will be enrolled in a randomized, comparative setting study conducted at 10-15 investigational sites. Sixty subjects will be randomized to undergo treatment in an office setting, and 40 subjects will be randomized to undergo treatment in a hospital or ambulatory surgical center (ASC) setting. Subjects will undergo a hysteroscopic tissue removal procedure to remove intrauterine polyps, type 0 fibroids, or type I fibroids. Saline infused sonohysterogram images (SIS) obtained at three months post treatment will be compared to pre-treatment images, to determine the percent reduction in target pathology volume. Additionally, subject self-reported pain scores (as rated on an 11 point scale) will compare pain occurring during the treatment procedure to the average pain level experienced during a PAP smear. Economic data will be collected and compared between the two treatment settings.

Description

Inclusion Criteria:

• Healthy female between 18 and 55 years of age
• Subject must be able to understand, read and sign the study specific informed consent forms after the nature of the study has been fully explained to her
• Subject is a pre-menopausal or peri-menopausal female, either nulliparous or parous
• Subject is experiencing AUB as confirmed by a symptom raw score of 23 or a calculated symptom score of 44.0 or higher on the Uterine Fibroid Scale and Health Related Quality of Life (UFS-QOL)
• Subject is indicated for myomectomy or polypectomy for benign appearing pathology, based on a hysteroscopic exam and measured by saline infused sonogram assessment within 30 days of the planned index procedure
• Subject exhibits intrauterine polyps and/or submucous myomas which, in the opinion of the treating physician, are compatible with office-based treatment (e.g. 15 minutes or less of cutting time) using the MyoSure device and meet at least one of the following criteria:
• One or more polyps, with at least one of the polyps ≥ 1.5 cm and ≤ 3.0 cm diameter and having broad based attachment to the uterine wall.

• Up to two Type 0 or Type 1 myomas with at least one of the myomas being ≥ 1.5 cm and none of the myomas being 3.0 cm diameter

  • If the first myoma is 3.0 cm, the second myoma must be ≤ 2.0 cm
  • Fundal myomas must be Type 0
• Polyps plus up to two Type 0 or Type I myomas with at least one of the myomas being ≥ 1.5cm and ≤ 3.0 cm
• The subject demonstrates a negative pregnancy test within 48 hours prior to the planned index procedure
• The subject must document a score of 5 or lower on the Pap Smear and Blood Draw scales of the Pain Tolerance Survey

Exclusion Criteria:

• Subject has known or suspected cancer, including breast, endometrial, and ovarian
• Contraindication and/or allergy to local anesthetic, or oral medications specified in the treatment protocol
• The subject has a history of chronic narcotic use
• Previous uterine artery embolization or other uterine artery occlusion procedure (Doppler or laparoscopic)
• Subject has blood borne pathogens-HIV, hepatitis B, CJD, etc.
• Subject has an IUD at the time of the procedure. A subject may be enrolled in the study if the IUD is removed prior to the treatment procedure

  • Type II submucosal myoma
  • Type O or Type I submucosal myoma > 3.0 cm
