Reviewers Raise TOPAS System Issues
FDA medical device reviewers say there are safety issues raised by the Astora Women’s Health TOPAS treatment for fecal incontinence to be considered by the Gastroenterology and Urology Devices Panel at its 2/25 meeting. A briefing document released in advance of the meeting says the device is a permanent implant consisting of a non-bioabsorbable mesh. It is intended to treat women with fecal incontinence who have failed more conservative therapies.
There are no legally marketed mesh devices for treating fecal incontinence, FDA says, and thus the advisory panel will be asked to discuss the clinical data provided to demonstrate a reasonable assurance of safety and effectiveness in support of a PMA approval for this “first of a kind” device.
The document says the TOPAS safety profile is based on adverse events collected from 152 subjects. A total of 115 treatment-related adverse events were reported in 72 (47.4%) subjects. The reviewers recommended that if the device is approved, the company should be required to undertake two post-approval studies on safety issues. The document says that the premarket study had limitations in terms of pain assessment, pelvic flood dysfunction, and organ prolapse. “A post-approval survey could be required to more thoroughly and frequently evaluate chronic pain, pelvic floor dysfunction, and pelvic organ prolapse,” the document says.
