ESS505 Pre-hysterectomy Protocol

July 6, 2016 updated by: Bayer

ESS505 Pre-hysterectomy Protocol: Safety and Short Term Effectiveness Study

This study has been designed to evaluate an investigational model of the Essure System for Permanent Birth Control. The investigational device is designed to offer all the advantages of the currently approved device. In addition, the investigational device offers immediate, permanent contraception without a three-month waiting period or 90-day confirmation test. This study has been designed to evaluate the effectiveness of the investigational device in causing tubal occlusion from insert placement through three months of wearing.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA).

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Experimental: ESS505-A (Essure, BAY1454033)
Bilateral hysteroscopic placement of the permanent birth control system, Model ESS505 insert with minimal polyethylene terephthalate (PET) fibers (investigational device model ESS505-A) followed by tubal occlusion evaluation by hysterosalpingogram (HSG) approximately 60 minutes following insert placement. A subsequent HSG was performed prior to the subjects' scheduled hysterectomy procedures at 30 (group 3), 60 (group 2) or 90 days (group 1) post insert placement.

Unilateral hysteroscopic placement of the permanent birth control system, Model ESS505 insert inclusive of polyethylene terephthalate (PET) fibers (investigational device model ESS505) and contralateral placement of the current commercially approved Essure device, model ESS305 followed by tubal occlusion evaluation by hysterosalpingogram (HSG) approximately 60 minutes following insert placement. A subsequent HSG was performed prior to the subjects' scheduled hysterectomy procedures at 30 (group 3), 60 (group 2) or 90 days (group 1) post insert placement. At the conclusion of the hysterectomy, the uterine cornua and fallopian tubes were sent to a pathology lab for histological preparation, and subsequent evaluation.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Number of Occluded Fallopian Tubes 60 Minutes After Placement of the Insert as Measured by an HSG Evaluation
Time Frame: 60 minutes after insert placement
Hysterosalpingogram (HSG) is an x-ray of the uterus and fallopian tubes after the injection of a contrast material (dye). This test evaluates tubal occlusion.
60 minutes after insert placement
Number of Occluded Fallopian Tubes 30 Days Following Placement as Measured by an HSG Evaluation
Time Frame: 30 days after insert placement
Hysterosalpingogram (HSG) is an x-ray of the uterus and fallopian tubes after the injection of a contrast material (dye). This test evaluates tubal occlusion. ESS505 and ESS505-A inserts are designed with the addition of an articulated hydrogel plug bonded to the distal portion of the insert with surgical grade adhesive and a nitinol support wire that remains inside the distal inner coil.
