Bioequivalence and comparative pharmacodynamics of insulin lispro 200?U/mL relative to insulin lispro (Humalog®) 100?U/mL.

ABSTRACT: Insulin lispro 200?U/mL (IL200) is a new strength formulation of insulin lispro (Humalog®, IL100), developed as an option for diabetic patients on higher daily mealtime insulin doses. This phase 1, open-label, 2-sequence, 4-period crossover, randomized, 8-hour euglycemic clamp study aimed to demonstrate the bioequivalence of IL200 and IL100 after subcutaneous administration of 20 U (U) to healthy subjects (n?=?38). Pharmacokinetic (PK) and pharmacodynamic (PD) responses were similar in both formulations. All 90%CIs for the ratios of area under the concentration-versus-time curve from time zero to the time of the last measurable concentration (AUC0-tlast) and maximum observed drug concentration (Cmax), as well as the total glucose infused throughout the clamp (Gtot) and the maximum glucose infusion rate (Rmax), were contained within 0.80 and 1.25. Time of maximum observed drug concentration (tmax) was similar between formulations, with a median difference of 15 minutes and a 95%CI of the difference that included zero. Inter- and intrasubject variability estimates were similar for both formulations. Both formulations were well tolerated. IL200 was bioequivalent to IL100 after subcutaneous administration of 20-U single doses, and PD responses were comparable between formulation strengths.

Project description:IntroductionThe aim of this study was to evaluate the efficacy and safety of ultra-rapid lispro (URLi) versus lispro in a subgroup analysis of Japanese adults with type 2 diabetes mellitus (T2DM) from the phase 3 PRONTO-T2D trial.MethodsAfter an 8-week lead-in period during which patients transitioned to insulin lispro 3 times a day before main meals in association with basal insulin (glargine or degludec), the patients were randomized to 26 weeks of double-blind URLi or lispro injected immediately prior to meals. The primary endpoint was change in hemoglobin A1c (HbA1c) from baseline to week 26 between URLi and lispro. The multiplicity-adjusted objectives were 1- and 2-h postprandial glucose (PPG) excursions after a test meal and change in HbA1c from baseline to week 26 in the URLi and lispro groups.ResultsResults were obtained from prespecified exploratory analyses of 26-week data in Japanese patients randomized to receive URLi (n = 47) or lispro (n = 46). Mean baseline HbA1c levels significantly improved during the lead-in period to a baseline value of 7.50% and 7.60% in patients subsequently randomized to the URLi and lispro treatment groups, respectively. At week 26, the least squares mean (LSM) difference in HbAc1 between the URLi and lispro groups was 0.13% (95% confidence interval [CI] - 0.12 to 0.39) (1.4 mmol/mol, 95% CI - 1.3 to 4.2). Although there were no significant differences in PPG excursions at any time-point, numerically smaller PPG excursions were consistently observed from 30 min to 3 h during the mixed-meal tolerance test in patients on URLi compared to those on lispro. LSM differences in PPG excursions at week 26 were - 10.5 mg/dL (95% CI - 32.7 to 11.7) (- 0.58 mmol/L, 95% CI - 1.82 to 0.65) at 1 h and - 14.9 mg/dL (95% CI - 40.3 to 10.5) (- 0.83 mmol/L, 95% CI - 2.24 to 0.58) at 2 h. There were no significant differences between treatments in rates of severe/overall hypoglycemia or incidence of treatment-emergent adverse events.ConclusionsURLi administered as prandial insulin in combination with basal insulin provides effective glycemic control when administered immediately before a meal in Japanese patients with T2DM. URLi was well tolerated in this population.Trial registrationClinicalTrials.gov, NCT03214380.

Project description:IntroductionWe evaluated the efficacy and safety of ultra-rapid lispro (URLi) in comparison to lispro in a subgroup analysis of Japanese adults with type 1 diabetes mellitus from the phase 3 PRONTO-T1D trial.MethodsAfter an 8-week lead-in to optimize basal insulin treatment, patients were randomized to 52-week double-blind mealtime URLi or lispro, or 26-week open-label postmeal URLi. The primary endpoint was change in hemoglobin A1c (HbA1c) from baseline (week 0) to week 26 between mealtime URLi and lispro. The multiplicity adjusted objectives were 1- and 2-h postprandial glucose (PPG) excursions after a meal test between mealtime URLi and lispro, and change in HbA1c from baseline to week 26 between postmeal URLi and mealtime lispro.ResultsThis manuscript presents pre-specified exploratory analyses of 26-week data from Japanese patients randomized to double-blind URLi (n = 62) or lispro (n = 59), or open-label URLi (n = 46). Mean baseline HbA1c levels were 7.52% for mealtime URLi, 7.44% for lispro, and 7.51% for postmeal URLi at randomization. At week 26, the least squares mean (LSM) difference compared to lispro was 0.04% (95% confidence interval [CI] - 0.14 to 0.22) for mealtime URLi, and 0.16% (95% CI - 0.04 to 0.35) for postmeal URLi. In comparison to lispro, mealtime URLi resulted in statistically significantly lower 1- and 2-h PPG excursions during the mixed-meal tolerance test. LSM differences were - 40.5 mg/dL, 95% CI - 59.5 to 21.4 (- 2.25 mmol/L, 95% CI - 3.3 to - 1.2) for 1-h PPG excursions and - 51.7 mg/dL, 95% CI - 81.7 to - 21.8 (- 2.87 mmol/L, 95% CI - 4.5 to - 1.2) for 2-h PPG excursions at week 26. There were no significant treatment differences in rates of severe/overall hypoglycemia, or incidence of treatment-emergent adverse events.ConclusionsMealtime and postmeal URLi provide effective and comparable glycemic control in Japanese patients. Mealtime URLi demonstrated more effective PPG control compared to lispro.Trial registrationClinicalTrials.gov, NCT03214367.
