FDA approved Medtronic’s MiniMed 670G hybrid closed looped system, the first FDA-approved device that is intended to automatically monitor glucose (sugar) and provide appropriate basal insulin doses in people 14 years of age and older with type 1 diabetes.
The MiniMed 670G hybrid closed looped system, often referred to as an “artificial pancreas,” is intended to adjust insulin levels with little or no input from the user. It works by measuring glucose levels every five minutes and automatically administering or withholding insulin. The system includes a sensor that attaches to the body to measure glucose levels under the skin; an insulin pump strapped to the body; and an infusion patch connected to the pump with a catheter that delivers insulin. While the device automatically adjusts insulin levels, users need to manually request insulin doses to counter carbohydrate (meal) consumption.
Risks associated with use of the system may include hypoglycemia, hyperglycemia, as well as skin irritation or redness around the device’s infusion patch. This version of this device is unsafe for use in children 6 years of age or younger and in patients who require less than eight units of insulin per day.
As part of this approval, the FDA is requiring a post-market study to better understand how the device performs in real-world settings. While the device is being approved today for use in people 14 years of age and older with type 1 diabetes, Medtronic is currently performing clinical studies to evaluate the safety and effectiveness of the device in diabetic children 7-13 years old.
