Key Terms

6 terms

time-in-range medical

"achieved American Diabetes Association (ADA) recommended goals for time-in-range (TIR)"

Time-in-range measures the percentage of time a person’s blood sugar stays within a pre-set target window, typically tracked continuously by glucose monitors. For investors, it’s a practical outcome metric: higher time-in-range signals a drug, device or care program is keeping patients healthier (like a thermostat maintaining a comfortable temperature), which can drive user adoption, clinical credibility, insurance support and commercial value.

bolus medical

"even on days when mealtime boluses were missed"

A bolus is a single, concentrated dose of a drug or fluid given all at once rather than slowly over time, like taking a quick gulp instead of sipping. Investors should care because a bolus can change how fast a medicine works, its side effect risks, and how regulators view dosing safety; those factors can materially affect clinical trial outcomes, approval chances and commercial prospects.

automated insulin delivery medical

"all automated insulin delivery systems, including the MiniMed™ 780G system"

A system that links a glucose sensor, an insulin pump, and control software so insulin is adjusted automatically to keep blood sugar near a target range, similar to a smart thermostat that regulates room temperature. It matters to investors because it replaces manual dosing with continuous, data-driven care, which can drive device sales, recurring subscription software services, better health outcomes, and regulatory interest—factors that affect market growth and company valuation.

glucose management indicator medical

"Glucose Management Indicator: 6.9% vs. 7.1%"

Glucose Management Indicator (GMI) is a number calculated from continuous glucose monitor (CGM) readings that translates average blood sugar patterns into an estimate comparable to a lab A1c result. Think of it as converting a stream of daily temperature readings into a single seasonal average; it helps clinicians and patients see overall control from device data. Investors care because GMI is often used to show how well diabetes drugs or devices work, influence regulatory decisions, and affect market adoption and reimbursement.

advanced hybrid closed loop medical

"after advanced hybrid closed loop (AHCL) initiation were included in analyses"

An advanced hybrid closed loop is a medical device system that combines a continuous glucose monitor and an insulin pump with smart software that automatically adjusts most insulin delivery to keep blood sugar in range, while still asking the user to enter carbohydrates for meals. Think of it like cruise control for blood sugar that handles routine adjustments but relies on the driver for big changes; for investors, adoption, regulatory approval, and payer coverage determine how much this product class can drive recurring sales and competitive advantage.

insulin pump medical

"using the MiniMed™ 780G insulin pump with a compatible Medtronic sensor"

A small wearable medical device that delivers measured doses of insulin automatically or on demand to help people with diabetes regulate their blood sugar, often replacing multiple daily injections. Investors care because these devices combine hardware, software and supplies to create recurring revenue, are subject to regulatory approval and reimbursement decisions, and can change competitive dynamics in a large, growing healthcare market much like a smartphone platform reshapes accessory sales.

GALWAY, Ireland, Jan. 7, 2026 /PRNewswire/ -- A new real-world retrospective analysis published in Diabetes Care showed that users of the MiniMed™ 780G system achieved American Diabetes Association (ADA) recommended goals for time-in-range (TIR)— even on days when mealtime boluses were missed. CareLink™ data showed that the studied user population achieved 76.3% TIR on missed bolus days when using SmartGuard™ technology with recommended optimal settings (100 mg/dL glucose target; two-hour active insulin time). The study investigated off-label user behavior as the system labeling requires users to announce meals when using SmartGuard™ technology. Deliberately not bolusing is an unapproved use of the device and is not recommended. While meal announcement is required, this study highlights the importance of optimized settings, especially when some users occasionally missed boluses.

Mealtime burden
Mealtimes are one of the biggest challenges for people living with type 1 diabetes and frequently linked to diabetes distress.^1,2 The constant need for decision-making and mental load around calculating carbohydrates and insulin requirements at mealtimes contributes to the overall burden of the condition. Missed boluses can significantly impact diabetes management and glycemic outcomes. A 2024 study published in Diabetes Technology & Therapeutics found that children and adolescents using AID systems missed an average of 2.2 boluses per day, with each additional missed bolus reducing TIR by nearly 10%.³

"While labeling requires meal bolusing for all automated insulin delivery systems, including the MiniMed™ 780G system, missed boluses are a reality in real-world use," said Jennifer McVean, MD, Senior Medical Affairs Director, Medtronic Diabetes, and lead investigator of the study. "Using real-world CareLink™ data, this analysis showed that when using recommended optimal settings, 71.2% of MiniMed™ 780G system users studies achieved ADA-recommended TIR goals on days when meal boluses were missed."

While announcing meals is required per the labeling of the MiniMed™ 780G system, the algorithm adjusts the delivery of insulin every five minutes based on sensor readings to auto-correct^† glucose levels—providing support when boluses are occasionally missed or carbohydrates are underestimated. The MiniMed™ 780G system is not approved for no bolusing for meals. 

Study Design & Key Findings
The study retrospectively analyzed real-world global CareLink user data (N=369,467) of those using the MiniMed™ 780G insulin pump with a compatible Medtronic sensor^‡ who experienced at least 10 days without bolusing (N=54,553) between January 2, 2020 to March 31, 2025.  

The analysis compared glycemic outcomes on missed bolus days with (N=12,723) and without (N=41,830) use of the recommended optimal settings. Those using the recommended optimal settings achieved significantly better outcomes than those using other settings in all age groups, including both type 1diabetes and type 2 diabetes populations:

• TIR: 76.3% recommended optimal settings vs. 69.3% for non-recommended optimal users
• Mean Sensor Glucose: 149 mg/dL vs. 160 mg/dL
• Glucose Management Indicator: 6.9% vs. 7.1%
• More than 61% of recommended optimal setting users met all three of the ADA recommended glycemic targets on missed bolus days compared to 36.6% in users of other settings

"These findings underscore the advanced capabilities of the MiniMed™ 780G system and its potential to ease the daily burden of diabetes care," said Que Dallara, EVP and President of Medtronic Diabetes. "Our goal is to empower people with technology that adapts to their lives, even when things don't go as planned."

‡	"CareLink Personal" data from January 2020 to March 31, 2025 were extracted from global MiniMed™ 780G system users who provided consent. Users with ≥10 days of sensor glucose data before automation and users with ≥10 days of sensor glucose data after advanced hybrid closed loop (AHCL) initiation were included in analyses. A "No Bolus" population was defined as users who did not administer boluses for ≥10 days; and only those days without user-initiated boluses were analyzed. These days were not required to be consecutive. The datasets included individuals who self-reported age (i.e. ≤15, 16-28, 29-42, 43-55, ≥56 years) and diagnosis of type 1 diabetes (T1D) or type 2 diabetes (T2D).
