MiniMed 530G with Enlite Automatically Stops Insulin Delivery If Sensor Glucose Levels Fall Below a Predetermined Threshold

MiniMed 530G with EnliteMedtronic, Inc. has announced the U.S. Food and Drug Administration (FDA) approval of the MiniMed 530G with Enlite, a breakthrough, first-generation artificial pancreas system with Threshold Suspend automation for people with diabetes. Medtronic’s system is the first in the United States that can automatically stop insulin delivery when sensor glucose values reach a preset level and when the patient doesn't respond to the Threshold Suspend alarm. The MiniMed 530G system incorporates the new Enlite sensor, Medtronic’s most accurate and comfortable continuous glucose sensor with a 31 percent improvement in overall accuracy from the previous generation.1

“We’re excited to bring yet another important ‘first’ to the United States. The MiniMed 530G with Enlite can help people gain better control of their diabetes versus multiple daily injections,” said Katie Szyman, president of the Diabetes business at Medtronic. “We are committed to advancing closed loop algorithms, continuous glucose monitoring and insulin delivery technologies to bring new artificial pancreas systems to market.”

The Enlite sensor delivers better comfort and reliable CGM accuracy. In addition to the 31 percent improvement in overall accuracy, the Enlite sensor detects up to 93 percent of hypoglycemia episodes when predictive and threshold alerts are on.2 The Enlite sensor is also 69 percent smaller3 than the previous Medtronic sensor, to deliver improved comfort in using continuous glucose monitoring. The new Enlite server provides a simpler sensor insertion process with a hidden-introducer needle.

Threshold Suspend automation stops insulin delivery with sensor glucose levels reach a preset level and if the patient is unable to respond to the Threshold Suspend alarm. The MiniMed 530G system was approved for use by people with diabetes ages 16 and older. Medtronic will conduct a post-approval study including children ages two and older. The Enlite sensor can be worn for six days.

As a condition of approval, in addition to the post-approval study, Medtronic will engage in direct patient follow up and will make certain manufacturing accommodations. These commitments are consistent with the product approval by the FDA and an accompanying warning letter issued to Medtronic on Sept. 19, 2013. Medtronic has already addressed many of the observations noted in the warning letter and is committed to resolving the remaining observations as quickly as possible and in accordance with the product approval requirements. Medtronic is committed to providing safe and effective products for people with diabetes.

Medtronic will begin ramping up production immediately to prepare for a launch of the MiniMed 530G in the next several weeks. In the meantime, customers can find additional product and important safety information at www.medtronicdiabetes.com.

Artificial Pancreas System with Threshold Suspend Automation
The MiniMed 530G system is the first system approved under the new product classification, “OZO: Artificial Pancreas Device System, Threshold Suspend,” created by the U.S. Food and Drug Administration. Threshold Suspend automation automatically stops the delivery of insulin if glucose levels reach a threshold, which can be set by a healthcare provider between 60-90 mg/dL. Once the threshold is met, the MiniMed 530G system will first alert the wearer with an alarm. If the individual is sleeping, unconscious or otherwise unable to react, the system will suspend all insulin delivery for two hours. Insulin delivery can be resumed at any time.

MiniMed® 530G with EnliteWhen Medtronic develops a next generation product for diabetes control, it will be designed to fully replicate the function of the pancreas by automatically monitoring glucose levels and delivering appropriate insulin to people with Type 1 diabetes; this future "fully automated artificial pancreas" will truly require minimal to no interaction by the patient user.
