Medtronic plc, a global leader in healthcare technology, is presenting a comprehensive body of new data at the American Diabetes Association’s 84th Scientific Sessions that showcases the benefits of the MiniMed™ 780G system.

With its advanced algorithm that provides autocorrections every 5 minutes, the latest data demonstrated that the MiniMed™ 780G system decreased rates of early morning hyperglycemia, known as dawn phenomenon, and improved overnight sleep

DUBLIN and ORLANDO, Fla., June 21, 2024 /PRNewswire/ -- Medtronic plc (NYSE: MDT), a global leader in healthcare technology, is presenting a comprehensive body of new data at the American Diabetes Association’s (ADA) 84^th Scientific Sessions that showcases the benefits of the MiniMed™ 780G system. New data shows how the system addresses hyperglycemia and nighttime burden, adding to the established body of evidence that demonstrates the system’s ability to tackle unique and burdensome challenges of diabetes, such as managing highs and meal-time management or carb counting, while also mirroring outcomes across a wide-ranging patient population.

Tackling hyperglycemia to improve long-term health with type 1 diabetes
Among the burdens of living with diabetes, hyperglycemia can often be overshadowed by hypoglycemia. Yet, in the U.S., only 26% of people living with diabetes achieve HbA1c levels of <7.0%.¹ Reducing the time spent with high blood sugars continues to be a significant unmet need as it can lead to serious health problems impacting multiple organs.²For children, prolonged highs can have adverse effects on memory, IQ, executive functioning, and learning.³

One cause of high blood sugars is the dawn phenomenon, an increase in glucose levels in the early morning.⁴ This can be a common occurrence for those living with diabetes and may add to feelings of frustration with diabetes. An encouraging new retrospective analysis of real-world data (n= 6026) showed that this morning peak was nearly eliminated for users who upgraded from the MiniMed™ 770G system to the MiniMed™ 780G system. The data assessed the elevation of sensor glucose levels >20 mg/dL from 3 - 6 a.m. compared to 12 – 3 a.m. at least 30% of the nights. The transition from the MiniMed™ 770G system to the MiniMed™ 780G system decreased dawn phenomenon rates from 12.2% to 4.5%. Time in Range also increased from 87.7% to 91.4% from 12 – 6 a.m., which is consistent with dawn phenomenon trends.

Early and consistent management of hyperglycemia is critical as it has protective effects on the body that can last for decades.⁵“For those living with type 1 diabetes, dawn phenomenon can be a stressful occurrence that feels out of one’s control,” explained Robert Vigersky, MD, Chief Medical Officer, Medtronic Diabetes. “The introduction of the MiniMed™ 780G system has made it easier to maintain target glucose range with less effort to protect against hyperglycemia.^6,7 It’s been an absolute gift for my patients who have struggled with stubborn highs throughout their diabetes journey.”

Reducing nighttime burden
For individuals living with type 1 diabetes, CGM-generated alerts and the need to deliver manual boluses disrupt sleeping through the night adding to the burden of diabetes. The MiniMed™ 780G system is designed to reduce the burden of diabetes throughout the day and night. Additional real-world data from a retrospective analysis presented at ADA (n=8019; <7 y/o, previously on the MiniMed™ 770G system who had greater than 14 nights on both systems) demonstrated that users had fewer overnight sleep interruptions and Time in Range improvements as a result of the automatic adjustments in insulin and correction^† of glucose levels every 5 minutes, including during sleep.^§ With the MiniMed™ 780G system, nighttime alerts decreased 45% for all users and 55% for those who used recommended optimal settings. Additionally, uninterrupted sleep, a greatly desired outcome for those living with diabetes, increased by 30 and 36 minutes per night, respectively. These results add to the diabetes burden reduction that MiniMed™ 780G system users experience with an advanced algorithm with frequent, every 5-minute autocorrections.

The continued evolution of the MiniMed™ 780G system to reduce burden
Along with evidence on the currently available MiniMed™ 780G system, additional data will be presented on the next iteration of the system,* which aims to further reduce diabetes management burden through its design. The system is intended to be paired with the Simplera Sync™ sensor, a disposable, all-in-one continuous glucose monitor (CGM) designed to require no overtape.

A 24-site, single arm study evaluated the use of the next iteration of the MiniMed™ 780G system algorithm paired with the Simplera Sync™ sensor. Results were promising across all clinical outcomes metrics including Time in Range (TIR), Time in Tight Range (TITR) and Time Above Range (TAR), compared to the run-in group where hybrid closed loop (auto basal only) or open-loop delivery was used. The study included the use of recommended optimal settings (ROS) (100 mg/dL set target with an active insulin time of 2 hours) related to TIR, TITR, and TAR.

“The MiniMed™ 780G system has firmly established itself as a proven automated insulin delivery system,” said study investigator Gregory Forlenza, MD, professor and pediatric endocrinologist at the Barbara Davis Center. “With the next iteration of the system and this next-generation Simplera Sync™ sensor, the overall experience for people living with type 1 diabetes could be enhanced and may prove to be a compelling option for diabetes management — particularly when leveraged in combination with recommended optimal settings.”

The MiniMed™ 780G system** is currently available for ages 7 and above in over 100 countries globally and will be launching with the Simplera Sync™ sensor in parts of Europe in late July. Currently, Simplera Sync™ is investigational and not approved for commercial use in the U.S.*
