Primary Outcome Measures:
  • Menstrual bleeding at 12 months compared to pre-procedure (baseline) [ Time Frame: 12 months from Baseline ] [ Designated as safety issue: No ]
  • Incidence of device and procedure-related adverse events within 12 months post-procedure [ Time Frame: 12 months ] [ Designated as safety issue: No ]
  • Surgical re-Intervention for menorrhagia at 12 months [ Time Frame: 12 months ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Uterine and fibroid volume at 12 months post-procedure compared to pre-procedure (baseline) as measured with contrast-enhanced MRI (magnetic resonance imaging) [ Time Frame: 12 month from Baseline ] [ Designated as safety issue: No ]
  • Fibroid Symptom severity and quality of life at 12 months post-procedure as compared to pre-procedure (baseline) using the Uterine Fibroid Symptom and Health Related Quality of Life (UFS-QoL) assessment tool. [ Time Frame: 12 months ] [ Designated as safety issue: No ]
  • General health outcome at 12 months post-procedure as compared to pre-procedure using the EQ-5D (a standardized instrument for use as a measure of health outcome) [ Time Frame: 12 months ] [ Designated as safety issue: No ]
  • Overall subject treatment outcome and satisfaction using the Overall Treatment Evaluation (OTE) [ Time Frame: 12 months ] [ Designated as safety issue: No ]

Estimated Enrollment: 150
Study Start Date: March 2009
Estimated Study Completion Date: February 2014
Primary Completion Date: January 2012 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Halt Procedure
In this single-arm study, subjects who have symptomatic uterine fibroids will have the Halt Procedure in which intra-abdominal ultrasound will guide RF ablation of uterine fibroids using the Halt System.
Device: Halt Procedure
The Halt 2000 Electrosurgical Radiofrequency Ablation System is indicated for use in percutaneous, laparoscopic and intraoperative, coagulation and ablation of soft tissue.
Other Names:
  • Halt
  • Halt2000
  • The Halt System
  • The Halt 2000 System

Detailed Description:

In this single-arm study, subjects who have symptomatic uterine fibroids will have laparoscopic surgery in which intra-abdominal ultrasound will guide RF ablation of uterine fibroids using the Halt System.

  Eligibility

Ages Eligible for Study:   25 Years and older
Genders Eligible for Study:   Female
Accepts Healthy Volunteers:   Yes
Criteria

Inclusion Criteria:

  • Are premenopausal and ≥ 25 years old
  • Have symptomatic uterine fibroids
  • Have a uterine gestational size ≤14 weeks as determined by pelvic exam
  • Have ≤ 6 (six) treatable fibroids in whom no single fibroid exceeds 7 cm in any diameter as measured by ultrasound or magnetic resonance imaging (MRI). Only Fibroids greater than 1cm in diameter should be treated in this study
  • Have a total uterine fibroid volume that does not exceed 300cc on ultrasound or contrast-enhanced MRI evaluation
  • Have clinical menorrhagia as indicated by menstrual blood loss of ≥160 mL to 500 ml during one baseline cycle or two baseline cycles within three months prior to treatment
  • Have a history of at least 3 months of menorrhagia within the last six months
  • Desire uterine preservation
  • Do not desire current or future childbearing
  • Have a normal coagulation profile (INR, Platelets, PT, and PTT)
  • Have had a normal Pap smear within the past 12 months
  • Are practicing non-hormonal or stable hormonal contraception
  • If the woman is not currently taking any hormonal contraceptives, has been off all hormonal contraceptives for a minimum of three months prior to study enrollment, and agrees to continue without change in regimen through the 12 months of follow-up OR
  • If the woman is currently taking hormonal contraceptives, has taken hormonal contraceptives for a minimum of three months prior to study enrollment, and agrees to continue without change in regimen through 12 months of follow up.**

    **Note: Hormonal contraceptive use must be terminated 30 days prior to treatment but should be resumed post-operatively within 60 days post treatment as instructed by the Investigator.

  • Are willing and able to comply with all study tests, procedures, and assessment tools
  • Are willing and able to return for all required follow up visits following study enrollment
  • Must pass a pre-operative health exam (ASA I-III)
  • Are capable of providing informed consent

Exclusion Criteria:

  • Have contraindications for laparoscopic surgery and/or general anesthesia. (Contraindications include anemia, defined as a hemoglobin level under 10 or hematocrit level less than 30.)
  • Have had prior pelvic surgery (with the exception of C-section, tubal ligation, or diagnostic laparoscopy), or are known to have significant intra-abdominal adhesions (defined as adhesions that would require extensive dissection to mobilize and view all surfaces of the uterus)
  • Have previously undergone endometrial ablation, uterine artery embolization, or uterine artery ligation, or any other uterine-preserving technique for reduction of menstrual bleeding (with the exception of hysteroscopic myomectomy > 1 year ago)
  • Patients requiring elective concomitant procedures
  • Have contraindications for magnetic resonance imaging (MRI)
  • Desire current or future childbearing
  • Are pregnant or lactating
  • Have taken any GnRh agonist within three months prior to the screening procedures
  • Have an implanted intrauterine or fallopian tube device for contraception that cannot or will not be removed one month prior to treatment
  • Have dysfunctional uterine bleeding or bleeding between periods
  • Have chronic pelvic pain not due to uterine fibroids
  • Have known or suspected endometriosis
  • Have known or suspected adenomyosis based on Ultrasound or MRI findings
  • Have active or history of pelvic inflammatory disease
  • Have a history of or evidence of gynecologic malignancy or pre-malignancy within the past five years
  • Have had pelvic radiation
  • Have a non-uterine pelvic mass
  • Have a cervical myoma
  • Have one or more pedunculated subserosal fibroids or "type zero" (completely intracavitary) submucous fibroids
