End date October 2012
Trial size 24 participants
Trial identifier NCT02023801, CIP0004


This is a clinical study without a formal hypothesis. The primary objective of the study is to evaluate the use of the Aurora Endometrial Ablation System in achieving a return to normal menstrual blood loss at 12 months post-treatment, in premenopausal women with menorrhagia due to benign causes for whom childbearing is complete or no longer wish to retain fertility.

Eligibility Criteria

Female participants from 25 years up to 50 years old.

Inclusion Criteria: 1. Refractory menorrhagia with no definable organic cause 2. Female subject from age 25 to 50 years 3. Uterine sound measurement of 6.0cm to 10.0cm (external os to internal fundus) 4. One of the following criteria: A. Documented history of menorrhagia secondary to dysfunctional uterine bleeding (DUB). B. If a pictorial blood loss assessment chart (PBLAC) scoring systems is used; a minimum PBLAC score of ≥150 for 3 months prior to study enrollment; OR, A minimum PBLAC score ≥150 for one month for women who either i. had at least 3 prior months documented failed medical therapy; or ii. had a contraindication to medical therapy; or iii. refused medical therapy 5. Premenopausal at enrollment as determined by FSH measurement ≤ 40 IU/ml 6. Not pregnant and no desire to be pregnant in the future 7. Patient agrees not to use hormonal contraception or any other medical intervention for bleeding during the study 8. Able to provide written informed consent using a form that has been approved by the reviewing IRB/EC 9. Subject agrees to follow-up exams and data collection, including ability to accurately use menstrual diaries 10. Subject who is literate or demonstrates an understanding on how to use menstrual diaries or how to collect and provide used sanitary products Exclusion Criteria: 1. Pregnancy or subject with a desire to conceive 2. Endometrial hyperplasia as confirmed by histology 3. Presence of active endometritis 4. Active pelvic inflammatory disease 5. Active sexually transmitted disease (STD), at the time of ablation. Note: Treatment of STD documented in the chart serves as sufficient evidence of infection resolution. Patient may be considered for study enrollment. 6. Presence of bacteremia, sepsis, or other active systemic infection 7. Active infection of the genitals, vagina, cervix, uterus or urinary tract at the time of the procedure 8. Known/suspected gynecological malignancy within the past 5 years 9. Known clotting defects or bleeding disorders 10. Untreated/unevaluated cervical dysplasia (except CIN I) 11. Known/suspected abdominal/pelvic cancer 12. Prior uterine surgery (except low segment cesarean section) that interrupts the integrity of the uterine wall (e.g., myomectomy or classical cesarean section) 13. Previous endometrial ablation procedure 14. Currently on medications that could thin the myometrial muscle, such as long-term steroid use (except inhaler or nasal therapy for asthma) 15. Currently on anticoagulants 16. Abnormal or obstructed cavity as confirmed by hysteroscopy or SIS, specifically: 1. Septate or bicornuate uterus or other congenital malformation of the uterine cavity 2. Pedunculated or submucosal myomas distorting the uterine cavity 3. Polyps likely to be the cause of the subject's menorrhagia 4. Intramural or subserosal myomas that distort the uterine cavity 17. Presence of an intrauterine device (IUD) which the patient is unwilling to have removed at the time of the operative visit 18. Presence of an implantable contraceptive device (e.g. Essure or Adiana). 19. Subject currently on hormonal birth control therapy or unwilling to use a non-hormonal birth control post-ablation (including a Mirena device). 20. Subject who is within 6-weeks post partum. 21. Any general health condition which, in the opinion of the Investigator, could represent an increased risk for the subject 22. Any subject who is currently participating or considers future participation in any other research of an investigational drug or device.
