The Set-Point Study: Evaluating Effects of Changing Glucose Target on Bionic Pancreas Performance

Participant wears the bionic pancreas, including an insulin and/or glucagon pump depending on which arm they are in. The 100 mg/dl arm for type 1 diabetes patients will deliver insulin and glucagon. The 100 mg/dl arm for type 2 diabetes patients will deliver just insulin. The 115 mg/dl arm will deliver insulin and glucagon. The 120 mg/dl arm will deliver just insulin. The 145 mg/dl arm will deliver just insulin. The 130 mg/dl and 110 mg/dl arms will deliver insulin and placebo, or insulin and glucagon, and will be double blinded.

Participant cares for their diabetes according to their usual practice, with blinded CGM monitoring. No medication will be administered by the study in this intervention.
