Conclusions • IDeg has a half-life of more than 25h, which is twice as long as that for insulin glargine. • Pharmacokinetic exposure is more consistent and evenly distributed across a 24h dosing interval for IDeg than for IGlar. • The glucose-lowering effect is more consistent and evenly distributed across a 24h dosing interval for IDeg than for IGlar.

Conclusion • Following injection, IDeg forms a depot of soluble and stable multi-hexamers in the subcutaneous tissue. • The gradual separation of IDeg monomers from the multi-hexamers results in a slow and continuous delivery of IDeg from the subcutaneous injection site into the circulation, leading to an ultra-long glucose-lowering effect beyond 40h.

Pharmacokinetics Danne et al. Diabetologia 2011;54(Suppl. 1):S425 (1047-P) (NN1250-1995)
Conclusions • The ultra-long pharmacokinetic profile of IDeg observed in adults is preserved in children and adolescents with type 1 diabetes. • Extent of exposure to IDeg was greater for adolescents than adults, and tended to be greater for children than adults; however, this is unlikely to have any clinical implications. As with other insulin products, IDeg should always be dosed according to individual needs. • IDeg is well tolerated in children, adolescents and adults. • Paediatric studies investigating the potential clinical benefits of this ultra-long-acting basal insulin appear warranted.

Conclusions • These results show that at steady-state: • IDeg has a flat and stable glucose-lowering effect. • The glucose-lowering effect of IDeg is consistent and evenly distributed over the 24h period. • Blood glucose remained at the clamp target level until end of the clamp and end of action was not reached in any patient. • These results confirm that IDeg has a duration of action beyond 26h in patients with type 2 diabetes.
