IDegAsp (insulin degludec + insulin aspart) for the management of type 2 diabetes: current status

The co-formulation insulin degludec/insulin aspart (IDegAsp) contains insulin degludec (IDeg), a basal insulin, and the rapid-acting insulin aspart (IAsp). Its unique pharmacodynamic profile provides a stable basal insulin action over a 24-h period due to the flat, ultra-long effect of IDeg, combined with prandial control from IAsp, which is unaffected by the basal component. IDegAsp provides a distinct mealtime insulin peak effect and reduces the likelihood of postprandial glucose excursions. The phase 2 and 3 clinical trial program demonstrates that IDegAsp provides effective glycemic control with lower rates of hypoglycemia compared with the current standard of care for insulins. Compared with premixed insulin formulations, IDegAsp allows mealtime flexibility, enabling the time of injection to be adjusted to a different meal(s) on a daily basis to suit changing needs, and has the potential to improve adherence rates. IDegAsp offers a promising new insulin strategy for the treatment of type 2 diabetes.
