My understanding is that the device that is close to FDA approval is an auto-injector rescue pen. It’s designed similarly to an EpiPen, designed to be easy to use (for example, 1. pull off safety, 2. inject) and to quickly deliver a single dose of glucagon in an emerency situation. For me, this is something I will actually carry around on a daily basis (I don’t with the current glucagon kits) and train friends and family how to use in an emergency. I also hope it’s something that I myself might be able to use in a sitautions where I’m afraid I might pass out or otherwise can’t access carbohydrates.
It will not be a device that’s easy to use for mini-dosing glucagon on a daily basis nor in a pump. However, the same company does have a mini-dose pen that is similar to an insulin pen, where you can dial up various doses of glucagon and use the pen repeatedly. Clinical trials for this mini-dose pen have already taken place in the US and Canada, so hopefully approval will come not too long after the rescue pen. This will be an excellent tool to add to my diabetes arsonal, because I have frequently mild to moderate lows and am trying to lose weight.
The company is also working on a glucagon that can be used in pumps. I believe there is also a second company (can’t recall the name) that is working on glucagon for pumps. This won’t be useful right away, but obviously will be crucial once true closed-loop systems become available. I’m upgrading pumps currently and am hopeful that the next time I upgrade pumps it’ll be to a fully closed-loop system that uses both insulin and glucagon. That will be amazing!
