We 142 are in the early stages of developing an insulin pump that adheres directly to the skin and administers insulin without the need for tubing, commonly known in the diabetes industry as a “patch pump.” We are also in the early stages of developing a first-of-its-kind bihormonal configuration of the iLet, which combines automated delivery of insulin and glucagon, the BG-raising hormone that protects against low blood sugar, or hypoglycemia, with adaptive closed-loop algorithms where all doses of both hormones are autonomously determined.

We believe that the iLet’s core value proposition of marrying effective glycemic control with the simplicity of use that is brought about by adaptive closed-loop algorithm insulin-dose determination may resonate particularly well among PCP who do not have the subspecialty-level of expertise, the resources, or the clinical bandwidth that is needed to initiate insulin-pump or hybrid closed-loop therapy or for the continual demand (such as adjustments at quarterly visits) those systems place on clinical practices in follow-on care. 141 A key element of our commercialization strategy is educating users and potential users on the use of the iLet.
