Since bolus insulin should be introduced as soon as basal insulin alone is insufficient to maintain glycaemic control, faster aspart is more relevant for patients with shorter duration of diabetes than those included in the present study.8 Along these lines, it is interesting that a phase III trial has shown that faster aspart, applied with a simple titration algorithm, can be added to a basal‐only regimen in people with T2D inadequately controlled on basal insulin plus OAD(s), with satisfactory outcome.23 This evidence concerns the gene INS and diabetes mellitus.
