What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
ESS305 (Essure, BAY1454032)Device
Essure Permanent Birth Control
NovaSureProcedure or surgery
Nova Sure Endometrial Ablation
| Study group | Role | What they receive |
|---|---|---|
| Essure+NovaSure | The group of women relying on Essure micro-inserts for permanent birth control when NovaSure is performed following a successful Essure Confirmation Test Receives: Device: ESS305 (Essure, BAY1454032); Procedure: NovaSure |
What is being measured
The primary outcome is the main question the study is designed to answer.
Number of Pregnancies at 1-year Time Point (1-year Pregnancy Rate)
Measured: 1 year after NovaSure Endometrial Ablation procedure
Number of Pregnancies at 3-year Time Point (3-year Pregnancy Rate)
Measured: 3 years after NovaSure Endometrial Ablation procedure
Secondary outcomes (1)
Number of Adverse Events (AEs) When NovaSure Endometrial Ablation Was Performed in the Presence of Essure Inserts
An adverse event (AE) is any untoward medical occurrence (i.e., any unfavorable and unintended sign [including abnormal laboratory findings], symptom, or disease) in a subject or clinical investigation subject after providing written informed consent for participation in the study. A serious adverse event (SAE) is classified as any untoward medical occurrence that results in death, is life-threatening, requires inpatient hospitalization or prolongation of existing hospitalization, results in persistent or significant disability/incapacity, is a congenital anomaly/birth defect, is another serious or important medical event (IME) as judged by the investigator, or requires intervention to prevent permanent impairment of a body function or damage to a body structure.
Measured: After 3-year follow-up
