Abstract
BACKGROUND AND OBJECTIVE: after a single subcutaneous dose in patients with type 2 diabetes mellitus (T2DM). METHODS: This was a phase I, randomised, two-period, two-treatment, double-blind, crossover study in 38 patients with T2DM. At each dosing visit, patients received either 15 units of URLi or Humalog, followed by a 10 h automated euglycaemic clamp procedure. Serum insulin lispro and blood glucose were measured. RESULTS: Insulin lispro appeared in the serum 5 min faster (p < 0.0001) and exposure was 6.4-fold greater in the first 15 min (p < 0.0001) with URLi versus Humalog. Exposure beyond 3 h postdose was 26% lower and the duration of exposure was 51 min shorter with URLi versus Humalog. Onset of insulin action was 13 min faster (p < 0.0001) and insulin action was 4.2-fold greater within the first 30 min (p < 0.0001) with URLi versus Humalog. Insulin action beyond 4 h postdose was 20% lower (p = 0.0099) with URLi versus Humalog. Overall insulin lispro exposure and total glucose infused were similar for URLi and Humalog. Both treatments were well tolerated. CONCLUSIONS: This is the first study to investigate URLi in patients with T2DM using a euglycaemic clamp procedure. URLi demonstrated ultra-rapid pharmacokinetics and glucodynamics in patients with T2DM. CLINICALTRIALS. GOV IDENTIFIER: NCT03305822.
