Essure Postmarket Study ‘Inadequate’: FDA
FDA says it has changed the status of the Bayer Essure postmarket surveillance study to “progress inadequate.” A 10/6 Essure information update says the status change for the birth control device study is due to the increase in interim lost to follow-up rates in both the Essure and laparoscopic tubal sterilization groups from the previous database lock.
“Per the study protocol,” the update says, “if a patient misses a follow-up visit but returns later and wishes to continue participation in the study, they will no longer be considered lost to follow-up. FDA requested Bayer develop and implement additional strategies to improve follow-up rates in the study.”
FDA also says it updated the Essure information Web page for patients and healthcare providers with the most current postmarket study information about device removal.
