ABSTRACT:
Methods: This was a phase I, two-period, randomised, double-blind, crossover glucose clamp study in younger adult (aged 18-45 years; n = 41) and elderly (aged ?65 years; n = 39) patients with T1DM. At each dosing visit, patients received either URLi or Humalog (15 units subcutaneously) followed by a 10 h automated euglycaemic clamp procedure. Serum insulin lispro and blood glucose were measured.
Results: Insulin lispro appeared in serum 6 min faster, and exposure was 7.2-fold greater over the first 15 min postdose with URLi versus Humalog in both age groups. Exposure beyond 3 h postdose was 39-41% lower, and exposure duration was reduced by 72-74 min with URLi versus Humalog in both age groups. Onset of insulin action was 11-12 min faster, and insulin action was 3-fold greater over the first 30 min postdose with URLi versus Humalog in both age groups. Insulin action beyond 4 h postdose was 44-54% lower, and duration of action was reduced by 34-44 min with URLi versus Humalog in both age groups. Overall exposure and total insulin action remained similar for both treatments. URLi and Humalog were well tolerated.
Conclusion: In patients with T1DM, URLi showed ultra-rapid pharmacokinetics and glucodynamics, with the differences between URLi and Humalog in elderly patients mirroring those in younger adults. ClinicalTrials.gov identifier: NCT03166124.

<h4>Background</h4>Ultra rapid lispro (URLi) is a novel insulin lispro formulation developed to more closely match physiological insulin secretion and improve postprandial glucose control. This study compared the pharmacokinetics, glucodynamics, safety, and tolerability of URLi and Humalog<sup>®</sup> in patients with type 1 diabetes mellitus (T1DM).<h4>Methods</h4>This was a phase I, two-period, randomised, double-blind, crossover glucose clamp study in younger adult (aged 18-45 years; n = 41) ...[more]
