Clinical Trial Summary

The EASE Clinical Trial is prospective, multi-center, single-arm (open-label), non-randomized, clinical trial to evaluate the Minitouch Endometrial Ablation System ("Minitouch System") in premenopausal women with menorrhagia.

Description:

The EASE Clinical Trial a prospective, multi-center, single-arm (open-label), non-randomized, clinical trial of the safety and effectiveness of endometrial ablation with the Minitouch System versus the FDA identified objective performance criteria (OPC) for global endometrial ablation (GEA) devices. The goal of the trial is to support reasonable safety and effectiveness of the investigational product compared to currently FDA-approved GEA devices. Only eligible participants will undergo the Minitouch procedure. Post-treatment follow-up occurs approximately 24-hours post-procedure (via phone call) and in-person office visits occur 2-weeks, 3, 6 and 12-months post-procedure. Additional longer term follow-ups occur (via phone call or in-person office visits) 24 and 36-months post-procedure. The expected length of participation is approximately 37 months (inclusive of one month for screening and 36-months of post-procedure follow-up).

12. Known clotting defects or bleeding disorders

13. Currently on medications that could thin the myometrium, such as long-term steroid use

14. Previous medical/surgical treatments, or has other conditions, that could lead to anatomic/pathologic weakness or thinning of the myometrium

15. Any general health, mental health or social situation which, in the opinion of the investigator, could represent an increased risk for the patient, or the ability of the patient to complete study requirements

21. Intramural or subserosal myomas > 3 cm in size, or any myoma that distorts the uterine cavity

22. Any patient who is currently participating or considering participation in any other research of an investigational drug or device

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Number of Trial Participants With Reduction in Menstrual Bleeding (PBLAC Score of =75)	The primary effectiveness endpoint is a clinical change in menstrual blood loss as assessed by the Pictorial Blood Loss Assessment Chart (PBLAC) data, a validated, patient self-reported menstrual diary scoring system. Success for the primary effectiveness endpoint was defined as reduction in menstrual bleeding to a PBLAC (Pictorial Blood Loss Assessment Chart) score of =75.; Scale information for PBLAC (Pictorial Blood Loss Assessment Chart): The scale minimum is 0, which indicates amenorrhea, i.e., no bleeding. There is no scale maximum. A score of 100 indicates eumenorrhea, i.e., normal menstrual bleeding. A lower PBLAC score indicates less bleeding and a higher PBLAC score indicates more bleeding.	Month 12 post-procedure
Primary	Number of Trial Participants With Device or Procedure-related Serious Adverse Events	The primary safety endpoint is the incidence of device or procedure-related serious adverse events.	Month 12 post-procedure
Secondary	Number of Trial Participants That Underwent Subsequent Medical or Surgical Intervention to Treat Abnormal Bleeding	Secondary safety outcome measures are the number of trial participants that underwent medical or surgical intervention to treat abnormal bleeding.	Month 12 post-procedure
