Abstract

Abstract The risk of inducing hypoglycaemia (low blood glucose) constitutes the main challenge associated with insulin therapy for diabetes. Insulin doses must be adjusted to ensure blood glucose values within normal range, but matching insulin doses to fluctuating glucose levels is difficult since even a slightly higher insulin dose than needed can lead to a hypoglycaemic incidence which can be anything from uncomfortable to life-threatening. It has thus been a long-standing goal to engineer a glucose-sensitive insulin that can auto-adjust its bioactivity in a reversible manner according to ambient glucose levels to ultimately achieve better glycaemic control while lowering the risk of hypoglycaemia. Here we report the design and properties of NNC2215, an insulin conjugate with bioactivity that is reversibly responsive to glucose over the physiological range as demonstrated in vitro and in vivo. NNC2215 was engineered by conjugating a glucose-binding macrocycle and a glucoside to insulin, thereby introducing a “switch” that can open and close in response to glucose and thereby equilibrate insulin between active and less active conformations. The insulin receptor affinity of NNC2215 increased 12-fold when glucose concentration was increased from 0 to 20 mM. In animal studies, the glucose-sensitive bioactivity of NNC2215 was demonstrated to lead to protection against hypoglycaemia while partially covering glucose excursions.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
