Ultra Rapid Lispro (URLi) Accelerates Insulin Lispro Absorption and Insulin Action vs Humalog^® Consistently Across Study Populations: A Pooled Analysis of Pharmacokinetic and Glucodynamic Data.

ABSTRACT:

Background and objective

Ultra rapid lispro (URLi) is a novel insulin lispro formulation developed to more closely match physiological insulin secretion and improve postprandial glucose control. This pooled analysis compared the pharmacokinetics and glucodynamics between URLi and Humalog^® in healthy subjects and patients with type 1 or type 2 diabetes mellitus.

Methods

The analysis included four randomized, double-blind, crossover, single-dose studies (healthy subjects [n = 74], patients with type 1 diabetes [n = 78], and type 2 diabetes [n = 38]) evaluating subcutaneous doses of 7, 15, or 30 U of URLi and Humalog during an 8- to 10-h euglycemic clamp procedure.

Results

The pooled analysis showed an ~ 5-min faster onset of appearance, an ~8-fold greater exposure in the first 15 min, a 43% reduction in exposure beyond 3 h, and a 68-min shorter exposure duration with URLi vs Humalog across all study populations and dose range. Compared with Humalog, URLi had a 10-min faster onset of action, a 3-fold greater insulin action in the first 30 min, a 35% reduction in insulin action beyond 4 h, and a 44-min shorter duration of action across all populations and dose range. Overall exposure and insulin action were similar between URLi and Humalog for each dose level and study population.

Conclusions

Across the studied populations and dose range, URLi consistently demonstrated a faster absorption, reduced late exposure, and overall shorter exposure duration compared with Humalog. Similarly, URLi demonstrated earlier insulin action while reducing late insulin action and shorter insulin action compared with Humalog across the study populations and dose range.

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.

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:IntroductionThe PRONTO-T1D study, which evaluated the efficacy and safety of ultra rapid lispro (URLi) versus lispro in adults with type 1 diabetes (T1D), met the primary endpoint of noninferiority of HbA1c change from baseline compared to lispro at 26 weeks. We present results of an additional 26-week treatment phase evaluating long-term efficacy and safety of URLi.MethodsIn this phase 3, treat-to-target study, subjects were randomized to double-blind mealtime URLi, lispro, or open-label postmeal URLi with insulin degludec or glargine for 26 weeks. Subjects in the double-blind URLi (n = 451) and lispro (n = 442) groups continued for another 26 weeks to assess long-term efficacy and safety.ResultsHbA1c increased marginally during the long-term maintenance period (week 26-52) in both groups to 7.47% (URLi) and 7.54% (lispro). At week 52, there were no statistically significant treatment differences in change from baseline HbA1c with a least-squares mean treatment difference (95% confidence interval) of - 0.06% (- 0.16, 0.03). Proportions of patients with HbA1c < 7% at week 52 were similar (URLi, 26.8%; lispro, 24.5%). Self-monitored blood glucose (SMBG) showed that 1-h (9.23 versus 10.14 mmol/L) and 2-h (8.40 versus 9.53 mmol/L) postmeal daily mean glucose was statistically significantly (p < 0.001) lower with URLi than lispro. The rate and incidence of severe, documented, and postprandial hypoglycemia (< 54 mg/dl [3.0 mmol/L]) were similar between treatments, but URLi demonstrated a 31% lower rate in the period more than 4 h after meals, (p = 0.023). Injection site reactions were reported by 3.3% of patients on URLi and 0.9% on lispro. The incidence of treatment-emergent adverse events was similar between treatments.ConclusionOverall glycemic control and improved postprandial glucose via SMBG were maintained after 52 weeks with URLi versus lispro, suggesting that the efficacy of URLi is preserved during long-term treatment in patients with T1D. No long-term safety issues were identified with URLi.Trial registrationClinicalTrials.gov, NCT03214367.
