Intended Use
SmartAdjust™ technology is intended for use with compatible integrated continuous glucose monitors (iCGM) and alternate controller enabled (ACE) pumps to automatically increase, decrease, and pause delivery of insulin based on current and predicted glucose values. SmartAdjust™ technology is intended for the management of type 1 diabetes mellitus in persons 2 years of age and older. SmartAdjust™ technology is intended for single patient use and requires a prescription.
Device Story
SmartAdjust™ technology is a software-only interoperable automated glycemic controller; part of the Omnipod 5 Automated Insulin Delivery System. Inputs: real-time glucose data from compatible iCGM. Processing: algorithm (residing on the Pod) calculates insulin micro-bolus adjustments based on current and predicted glucose values. Outputs: automated insulin delivery commands to the connected ACE Pump. Used in ambulatory settings by patients with type 1 diabetes. The system operates in either 'Automated Mode' (closed-loop) or 'Manual Mode' (open-loop). Healthcare providers use the system to manage glycemic control; patients benefit from automated insulin titration to maintain target glucose ranges (110-150 mg/dL).
Clinical Evidence
No new clinical trials conducted. Evidence consists of dynamic in-silico simulations using virtual subjects derived from pivotal study K203774. Simulations challenged the algorithm with 6,480 scenarios per subject, varying glycemic conditions, meal profiles, and iCGM error models (lag, bias, noise) over 12-hour durations. Endpoints included hypoglycemia risk, hyperglycemia risk, and glycemic outcomes (time in range, above range, below range). Results confirmed the algorithm maintains performance within acceptable safety limits under updated iCGM specifications.
Technological Characteristics
Software-only iAGC; resides on Omnipod 5 ACE Pump and App. Connectivity via Bluetooth Low Energy. Operates as a closed-loop controller for insulin delivery. Complies with ANSI AAMI ISO 14971:2019 (risk management) and ANSI AAMI IEC 62304:2006/A1:2016 (software lifecycle).
Indications for Use
Indicated for management of type 1 diabetes mellitus in persons 2 years of age and older. Contraindicated in patients <2 years old, those requiring <5 units insulin/day, pregnant women, critically ill patients, dialysis patients, and those taking hydroxyurea. Requires adequate hearing/vision for system alerts.
Regulatory Classification
Identification
An interoperable automated glycemic controller is a device intended to automatically calculate drug doses based on inputs such as glucose and other relevant physiological parameters, and to command the delivery of such drug doses from a connected infusion pump. Interoperable automated glycemic controllers are designed to reliably and securely communicate with digitally connected devices to allow drug delivery commands to be sent, received, executed, and confirmed. Interoperable automated glycemic controllers are intended to be used in conjunction with digitally connected devices for the purpose of maintaining glycemic control.
Special Controls
*Classification.* Class II (special controls). The special controls for this device are:(1) Design verification and validation must include: (i) An appropriate, as determined by FDA, clinical implementation strategy, including data demonstrating appropriate, as determined by FDA, clinical performance of the device for its intended use, including all of its indications for use. (A) The clinical data must be representative of the performance of the device in the intended use population and in clinically relevant use scenarios and sufficient to demonstrate appropriate, as determined by FDA, clinical performance of the device for its intended use, including all of its indications for use. (B) For devices indicated for use with multiple therapeutic agents for the same therapeutic effect ( *e.g.,* more than one type of insulin), data demonstrating performance with each product or, alternatively, an appropriate, as determined by FDA, clinical justification for why such data are not needed.(C) When determined to be necessary by FDA, the strategy must include postmarket data collection to confirm safe real-world use and monitor for rare adverse events. (ii) Results obtained through a human factors study that demonstrates that an intended user can safely use the device for its intended use. (iii) A detailed and appropriate, as determined by FDA, strategy to ensure secure and reliable means of data transmission with other intended connected devices. (iv) Specifications that are appropriate, as determined by FDA, for connected devices that shall be eligible to provide input to ( *e.g.,* specification of glucose sensor performance) or accept commands from (*e.g.,* specifications for drug infusion pump performance) the controller, and a detailed strategy for ensuring that connected devices meet these specifications.(v) Specifications for devices responsible for hosting the controller, and a detailed and appropriate, as determined by FDA, strategy for ensuring that the specifications are met by the hosting devices. (vi) Documentation demonstrating that appropriate, as determined by FDA, measures are in place ( *e.g.,* validated device design features) to ensure that safe therapy is maintained when communication with digitally connected devices is interrupted, lost, or re-established after an interruption. Validation testing results must demonstrate that critical events that occur during a loss of communications (*e.g.,* commands, device malfunctions, occlusions, etc.) are handled and logged appropriately during and after the interruption to maintain patient safety.(vii) A detailed plan and procedure for assigning postmarket responsibilities including adverse event reporting, complaint handling, and investigations with the manufacturers of devices that are digitally connected to the controller. (2) Design verification and validation documentation must include appropriate design inputs and design outputs that are essential for the proper functioning of the device that have been documented and include the following: (i) Risk control measures to address device system hazards; (ii) Design decisions related to how the risk control measures impact essential performance; and (iii) A traceability analysis demonstrating that all hazards are adequately controlled and that all controls have been validated in the final device design. (3) The device shall include appropriate, as determined by FDA, and validated interface specifications for digitally connected devices. These interface specifications shall, at a minimum, provide for the following: (i) Secure authentication (pairing) to connected devices; (ii) Secure, accurate, and reliable means of data transmission between the controller and connected devices; (iii) Sharing of necessary state information between the controller and any connected devices ( *e.g.,* battery level, reservoir level, sensor use life, pump status, error conditions);(iv) Ensuring that the controller continues to operate safely when data is received in a manner outside the bounds of the parameters specified; (v) A detailed process and procedures for sharing the controller's interface specification with connected devices and for validating the correct implementation of that protocol; and (vi) A mechanism for updating the controller software, including any software that is required for operation of the controller in a manner that ensures its safety and performance.

Critical events to be stored by the controller must, at a minimum, include: (i) Commands issued by the controller, and associated confirmations the controller receives from digitally connected devices; (ii) Malfunctions of the controller and malfunctions reported to the controller by digitally connected devices ( *e.g.,* infusion pump occlusion, glucose sensor shut down);(iii) Alarms and alerts and associated acknowledgements from the controller as well as those reported to the controller by digitally connected devices; and (iv) Connectivity events ( *e.g.,* establishment or loss of communications).(5) The device must only receive glucose input from devices cleared under § 862.1355 (integrated continuous glucose monitoring system), unless FDA determines an alternate type of glucose input device is designed appropriately to allow the controller to meet the special controls contained within this section. (6) The device must only command drug delivery from devices cleared under § 880.5730 of this chapter (alternate controller enabled infusion pump), unless FDA determines an alternate type of drug infusion pump device is designed appropriately to allow the controller to meet the special controls contained within this section.
