Interventional
Description of intervention(s) / exposure
Treatment: Devices - CamAPS HX
Other interventions - Standard insulin therapy with glucose sensor

Experimental: Fully closed-loop insulin delivery (CamAPS HX) - The automated closed loop system (CamAPS FX) will consist of:

* YpsoPump insulin pump (Ypsomed, Burgdorf, Switzerland)
* FreeStyle Libre 3 glucose sensor (Abbott Diabetes Care, CA, USA)
* Smartphone hosting CamAPS HX app with the Cambridge model predictive control algorithm
* Cloud upload system to review CGM/insulin data.

Participants will use the fully closed-loop system for 26 weeks at home

Active comparator: Standard insulin therapy with glucose sensor - Usual insulin therapy and FreeStyle Libre 3 glucose sensor (Abbott Diabetes Care, CA, USA) for 26 weeks at home.
