Welcome back to Diabetes Dialogue: Technology, Therapeutics, & Real-World Perspectives!
Tubeless insulin delivery is entering a new phase of competition, as Beta Bionics announced FDA clearance of Mint, its first patch pump, alongside a forthcoming algorithm update designed to individualize glycemic targets without carb counting.1,2
On a recent episode of Diabetes Dialogue, hosts Diana Isaacs, PharmD, and Natalie Bellini, DNP, discussed the clearance and its implications for practice. The conversation centered on device specifications, insurance pathways, and an upcoming three-mode dosing algorithm called 3D Intelligence.
Mint is a tubeless, three-day-wear pump holding 200 units of insulin, built around a nonrechargeable two-year battery and IPX8 water resistance rated to five feet for 60 minutes. It pairs with iOS and Android at launch and requires no phone for priming, addressing adherence barriers seen with existing automated insulin delivery systems. Sensor compatibility includes the Dexcom G7 and Abbott's Libre 3 Plus, with Libre Dual and Senseonics' Eversense integration planned to follow.
Beta Bionics expects to begin shipments in the first quarter of 2027, targeting production of approximately 1.5 million units for the year, with at least 40% of payers anticipated to offer pharmacy-benefit coverage at launch. This model would allow patients on any current pump, including those previously limited to durable medical equipment acquisition, to access Mint through pharmacy channels once coverage is in place.
The forthcoming 3D Intelligence update introduces three insulin-dosing profiles built on real-world data from more than 40,000 current iLet users, expanding on the meal-announcement-only interface which has defined the iLet since launch. The original mode preserves the existing algorithm, the optimized mode aims to reduce hypoglycemia while maintaining time above range, and the conservative mode delivers a more measured correction response for patients at higher hypoglycemia risk, such as older adults. The update remains pending FDA clearance but is expected to reach existing iLet users via software update around the Mint launch.
Expanded sensor compatibility, dual-platform smartphone support, and pharmacy-benefit access position Mint to broaden automated insulin delivery uptake beyond populations previously constrained to durable medical equipment coverage. Combined with the 3D Intelligence update, the changes reflect a shift toward individualized dosing within a system historically defined by simplicity, without reintroducing manual basal rates or carb-ratio calculations. As competing patch pump programs advance through the FDA pipeline, the addition reinforces momentum toward algorithm-driven, low-burden insulin delivery across the type 1 diabetes population.
