Medtrum TouchCare Nano
Medtrum
A fully tubeless, phone-controlled hybrid closed loop: a low-profile patch pump and 14-day CGM run together off Medtrum's APGO algorithm, with an unusual 'log the meal, skip the carb count' auto-meal feature. CE-marked; a 160-person type 1 pivotal trial is underway.
The scorecard
Manufacturer reports time-in-range rises early and holds, with further gains using auto-meal handling, but no peer-reviewed TIR figure is yet published; a randomized type 1 trial (NCT06363916) is recruiting.[4]
Closed-loop algorithm modulates and suspends basal to defend against lows; safety/efficacy is the explicit endpoint of the ongoing pivotal trial rather than an established published result.[4]
Hybrid closed loop automating basal 24/7 plus optional automatic meal-bolus delivery via Auto Meal Handling — logging a meal without carb counting is rare among AID systems.[3]
Fully tubeless patch pump plus on-body CGM controlled entirely from a smartphone, with no separate handheld controller (PDM) to carry.[1]
Average-glucose lowering is implied by the TIR claims but not yet quantified in a published type 1 study; pending the pivotal trial readout.[4]
Algorithmic basal modulation aims to smooth variability, but no published glucose-variability metrics are available yet for this system.[4]
Offers adjustable glucose targets the user can raise around activity; no published exercise-specific outcome data.[1]
User-set glucose targets and meal logging give meaningful control; the algorithm is proprietary (APGO) and not openly configurable.[1]
CE MDR Class III certified and rolling out across multiple international markets including Europe and Brazil; not US-cleared and availability is uneven.[2]
Glycemic criteria are scored on the levels actually achieved in large real-world Type 1 diabetes cohorts — not the headline improvement over a trial's baseline (an improvement that looks bigger when the starting population was doing poorly). Type 2 diabetes trial data is never used to score a Type 1 system; where only improvement data exists, it informs the rationale, not the score. Freedom captures form factor and wearability, so a tubeless system is rewarded for the mobility a tubed one can't match.
The full picture
The Medtrum TouchCare Nano is a fully tubeless hybrid closed loop: a small, low-profile patch pump and a 14-day continuous glucose sensor work together under Medtrum's proprietary APGO algorithm to automate basal insulin around the clock. There is no separate handheld controller — the pump and CGM are run entirely from a smartphone app, which keeps the on-body footprint minimal and the carry burden low. Its most distinctive feature is Auto Meal Handling: rather than counting carbohydrates and entering a number, the user simply logs that a meal is happening, and the system delivers and adjusts a meal bolus dynamically from the glucose response. Medtrum says time in range improves soon after starting and holds steady, with additional gains when auto-meal handling is on, but those claims are not yet backed by a peer-reviewed type 1 outcome; a randomized trial in 160 people with type 1 diabetes (NCT06363916), with time in range 70-180 mg/dL as the primary endpoint, is recruiting. The system holds EU CE MDR Class III certification and is expanding across international markets including Europe and Brazil. It is not cleared in the US, and as a hybrid (not fully closed) loop it still expects the user to log meals.
