Device Description
GO-PEN® is an assembly of a durable pen-shaped dosing unit with a special disposable sterile reservoir that fits into the dosing unit. The GO-PEN® device can only be used with NovoLog® U-100 insulin aspart for injection. The user is intended to fill up the disposable reservoir with 1.3 mL of insulin from a 10 ml vial and mount it on the dosing unit. The GO-PEN® device allows the user to set the desired dose from 1 to 60 Units in 1 Unit increments using the dial feature. Once the GO-PEN® disposable reservoir is filled, it can be used over a period of up to 3 days at room temperature (max. 30°C/86°F) for multiple injections of precise doses of insulin. When the reservoir is empty or the time has been exceeded, the reservoir must be discarded, and a new sterile reservoir is used for the next filling. GO-PEN® is used with standard single-use hypodermic needles with a luer lock which are supplied separately by the user.

| Indications for Use | GO-PEN® is a reusable insulin pen intended for the self-injection of NovoLog® (U-100, insulin aspart for injection) available in 10 ml vials. | HumaPen Savvio is a reusable insulin pen intended for the self-injection of HUMALOG® (U-100, insulin lispro for injection) available in 3 mL cartridges using disposable pen needles (sold separately). | The proposed and predicate devices are intended to be used with the same strength of fast-acting insulin, but a different kind of insulin and that is provided in a different format – the predicate device requires a pre-filled pen cartridge while the proposed device requires the user to fill a reservoir from a vial. The proposed device allows for the use of a different type of fast-acting insulin, NovoLog®. These differences do not affect substantial equivalence. Both devices deliver U-100 rapid-acting insulin via reusable pens with disposable needles. The proposed device uses insulin from a vial, while the predicate uses pre-filled cartridges. This difference in insulin loading is addressed in the design and usability documentation. Once filled, the devices operate similarly. Although the insulins differ by brand (NovoLog® vs. HUMALOG®), both are rapid-acting and functionally equivalent for self-injection. |

|---|---|---|---|
| Insufficient Remaining Dose feature | The pen-injector will allow a user to dial a dose that is greater than what is remaining in the reservoir. Once the pen-injector has completed the delivery of the insulin available within the reservoir (i.e., empties the reservoir), the portion of the dose that was not injected will be displayed on the dose dial; that is, the dose dial will not return to "0" as it would if the entire dose was delivered. This remaining dose is to be administered after replacing the reservoir. | Patient cannot dial more than the deliverable amount of insulin remaining in the cartridge, prior to injection. | ISO 11608-1:2022, §5.6(k) lists four options for IRD features. The GO-PEN® uses method (4) while the HumaPen Savvio uses method (1). This difference does not impact substantial equivalence as both pens comply with the standard and provide methods of completing a dose when the pen does not contain sufficient insulin. |
| Cartridge Volume | 1.3 mL | 3 mL | The GO-PEN® device holds less insulin than the predicate device. This difference does not impact substantial equivalence as both users must refill when empty. |
| Mechanism | Mechanical pen-injector/needle-based injection system | Mechanical pen-injector/needle-based injection system | Same |
| Delivery Accuracy | Meets ISO 11608-1:2022 requirements | Meets ISO 11608-1:2014 requirements | Same. Performance testing of the HumaPen Savvio was performed in accordance with ISO 11608-1:2014. A newer version of the standard has been published which has no impact on the test methods or requirements. Testing performed in accordance with the 2022 version also meets the requirements of the 2014 version. |
| Dial Increments | 0.01 mL per increment providing one unit (1U) dose increments | 0.01 mL per increment providing one unit (1U) dose increments | Same |
| Maximum Delivered Dose | 60 Units | 60 Units | Same |
| Use Life | Durable Pen – 2 years in packaging; 3 years once use begins | ||
| Reservoir – 2 years in packaging; 3 days once filled | |||
| Pull-rod – 12 uses or approximately 3 months | 6 years | The GO-PEN® durable pen has a shorter use life than the predicate device which remains substantially equivalent as the use life difference does not impact the intended use or technological characteristics of the device. |

SUBSTANTIAL EQUIVALENCE
The indications for use for the predicate device are substantially equivalent to the proposed indications for use for the GO-PEN®. Any differences in the technological characteristics between the devices do not raise any different questions of substantial equivalence. Thus, the GO-PEN® is substantially equivalent to the predicate device.
