About this trial

The main objective of this study is to evaluate the effect of fully automated closed-loop glucose control on renal tissue oxygenation among people with type 2 diabetes and chronic kidney disease.

This is a single-center, open-label parallel design study that will compare 26 weeks of fully-automated closed-loop glucose control with standard insulin therapy and continuous glucose monitoring, following a run-in period. A total of up to 76 adults with type 2 diabetes and chronic kidney disease will be recruited through outpatient diabetes and nephrology clinics.

The primary outcome is renal tissue oxygenation measured using blood oxygenation level-dependent magnetic resonance imaging at 26 weeks. Other key outcomes include glycated hemoglobin at 26 weeks and time spent with glucose levels within and above the target glucose range (3.9-10.0mmol/L). Other glycemic and renal outcomes (including renal function) will also be assessed, as well as patient-reported outcome measures using validated questionnaires. Safety evaluations include severe hypoglycemic episodes and other adverse and serious adverse events.

Treatments tested in this trial

  • CamAPS HX

    Device

    The CamAPS HX fully closed-loop system consists of an insulin pump, a continuous glucose monitoring (CGM) sensor, as well as the CamAPS HX app, which resides on a smartphone and communicates wirelessly with the insulin pump.

  • Standard insulin therapy with CGM

    Device

    Participants will continue their standard insulin therapy with a Freestyle Libre 3 CGM

Treatment groups

76 Participants
are divided into 2 treatment groups
Group A: Fully closed-loop insulin delivery (CamAPS HX)Experimental treatment 1 intervention
Group B: Standard insulin therapy with CGMActive comparator 1 intervention
