Bigfoot is working on smart insulin pen caps and a paired app with a lofty goal: “Close the loop” for injection users. The caps will read how much insulin is in both long-acting and mealtime disposable insulin pens, send the data to a smartphone app, and then deliver recommended insulin dose changes based on patterns from a next-gen FreeStyle Libre continuous glucose monitor. The cap will include a screen, with one color cap to be used for long-acting and another for mealtime insulin. Bigfoot’s system will allow users to more easily switch between using pens and using a pump. The current plan is to make the whole insulin automation service available for one prescription and one monthly copay. Bigfoot hopes to launch both of its systems in 2020 with Abbott’s next-gen FreeStyle Libre CGM, an Inject system and its Loop system with a pump (hybrid closed loop).
