Post-marketing Surveillance Study of A.M.I. Protector Adjustable Gastric Band

United Kingdom200 participantsStarted 2013-01

Plain-language summary

The laparoscopic adjustable gastric band (LAGB) is a safe and effective surgical intervention for chronically obese patients who have exhausted all non-surgical weight loss treatments. Numerous published studies have confirmed both the safety and efficacy of the LAGB and its beneficial impact on obesity-associated conditions, such as type 2 diabetes, joint and back pain and hypertension. The A.M.I. Protector Band is a modification of an existing gastric band (the A.M.I. Soft Gastric Band) which has been in use since 2001 and which has been shown to be both safe and effective. The specific design modification is in the form of a section of mesh, which provides support to the gastric pouch and which further restricts food portion sizes. The expectation is that this will deliver optimal weight loss whilst having the maximum possible impact on obesity-associated conditions such as type 2 diabetes and hypertension. In the longer term, there is also the possibility that the Protector Band will reduce the incidence of band complications such as slippage and dilatation (or stretching) of the gastric pouch. In this study we will recruit approximately 200 patients who will then undergo surgical implantation of the A.M.I. Protector Band. The study participants will then be followed for a period of 3-years, during which time we will record weight loss, changes in co-morbid conditions such as diabetes and the incidence of band complications, including slippage and pouch dilatation.

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
