Glucose entering the beta cell is metabolised, raising ATP, closing potassium channels, depolarising the membrane and opening calcium channels; calcium entry triggers insulin granule release. Incretin receptor signalling raises cyclic AMP, which increases the amount of insulin released for a given calcium signal.
Because the incretin signal acts on the gain rather than the trigger, it does little when the glucose-driven trigger is absent.
Agents whose effect on insulin is glucose-dependent carry much less risk of driving glucose too low than agents that stimulate secretion regardless of glucose. This is a class property of incretin-based agents and is documented across their trial literature.
In the Lancet 2023 trial the authors reported no severe hypoglycaemia among participants receiving retatrutide, which is the expected finding for this mechanism in a population not on insulin or sulfonylureas.
Glucagon receptor agonism raises glucose output from the liver, which works against glycaemic control. The design relies on incretin-driven insulin secretion to offset it, and the glucose-dependence of that offset is part of why the net effect in the trials was favourable rather than neutral.
That is the mechanistic reading; the empirical result is in the phase 2 glycaemic data.
