AIM: To compare the pharmacokinetics (PK), glucodynamics (GD), and tolerability following single and multiple daily subcutaneous (SC) doses of ultra rapid lispro (URLi) and Humalog® in patients with type 1 diabetes mellitus (T1D).
MATERIALS AND METHODS: This was a two-part, randomized, double-blind, Phase 1b study. Part A used a six-period crossover design to assess PK and GD response to a solid mixed meal tolerance test (MMTT) following a single dose of URLi or Humalog administered 15 min before, immediately before, and 15 min after the start of the meal. Part B evaluated URLi or Humalog during 2 weeks of multiple daily dosing with a parallel design. The PK and GD were assessed following MMTTs at the beginning and end of the 2-week period when insulins were administered immediately before the start of the meal.
RESULTS: URLi increased the insulin exposure within the first 30 min postdose by 2.2-fold and reduced the time to early half-maximal drug concentration by 37% compared with Humalog. Overall, URLi resulted in better postprandial glucose lowering when dosed before, immediately before, or after a meal compared with Humalog. Comparing the same meal-to-dose timing between the insulins, postprandial glucose excursion over 5 hours was reduced by 40%-44% for all three dose timings (-15, 0, and +15 min) with URLi, achieving statistical significance for the 0- and +15-min timings. The PK and GD profiles were sustained after daily SC dosing for 2 weeks in patients with T1D. The number of documented hypoglycaemic events was similar between URLi and Humalog during the postprandial period of the MMTTs and the outpatient period.
CONCLUSIONS: URLi showed accelerated insulin lispro absorption and greater postprandial glucose reduction at different meal-to-dose timings compared with Humalog and was well tolerated in patients with T1D.
