Insulin glargine 300 U/mL for basal insulin therapy in type 1 and type 2 diabetes mellitus.

ABSTRACT: OBJECTIVE:To review published clinical studies on the efficacy and safety of new insulin glargine 300 units/mL (Gla-300), a new long-acting insulin analog, for the treatment of type 1 and type 2 diabetes mellitus (T1DM, T2DM). MATERIALS AND METHODS:Data sources comprised primary research articles on Gla-300, including pharmacodynamic, pharmacokinetic, and clinical studies. RESULTS:In pharmacodynamic and pharmacokinetic studies, Gla-300 showed a flatter time-action profile and longer duration of action than Gla-100. Noninferiority of Gla-300 versus Gla-100 for lowering of glycated hemoglobin was demonstrated in Phase III clinical studies covering a range of T1DM and T2DM patient populations. Over 6-12 months of follow-up, Gla-300 consistently showed comparable glycemic efficacy with less hypoglycemia vs Gla-100, even during the first 8 weeks of treatment. Although titrated insulin doses were 11%-17% higher with Gla-300 vs Gla-100, changes in body weight were similar or favored Gla-300. CONCLUSION:Clinical studies provide evidence that the pharmacodynamic and pharmacokinetic properties of Gla-300 may translate into clinical benefits in both T1DM and T2DM. Gla-300 may provide a new option for people initiating basal insulin, those requiring higher basal insulin doses, those with T1DM, and those who may be at increased risk for hypoglycemia, such as people with chronic kidney disease, the elderly, and those with cardiovascular comorbidities.

Project description:IntroductionNew insulin glargine 300 U mL(-1) (Gla-300) is a basal insulin that shows more stable and prolonged pharmacokinetic and pharmacodynamic profiles than insulin glargine 100 U mL(-1) (Gla-100). This study used continuous glucose monitoring (CGM) to compare 24-h glucose profiles in a Japanese population using Gla-300 versus Gla-100.MethodsThis was an exploratory 8.4-week, single-center, 2-sequence, 2-period, open-label crossover study. Japanese adults with type 1 diabetes mellitus (T1DM) treated with basal-bolus insulin, with glycated hemoglobin (HbA1c) 6.5-10.0% and median fasting self-monitored plasma glucose concentration ≤13 mmol L(-1), were randomized to Gla-300 followed by Gla-100 (subgroup 1) or vice versa (subgroup 2), with no washout period. CGM was performed on the last 3 days of the screening period and each treatment period. Primary endpoint was comparison of 24-h glucose variability (area under the curve [AUC]mean_24 h) on the second day of each CGM measurement with Gla-300 versus Gla-100. Baseline and end of treatment period values for HbA1c, fasting plasma glucose (FPG) and daily basal/mealtime insulin doses were recorded. Hypoglycemia and adverse events (AEs) were recorded.ResultsTwenty participants were randomized (10 to subgroup 1 and 10 to subgroup 2). Participants showed comparable glucose variability over 24 h (AUCmean_24 h during treatment with Gla-300 or Gla-100 (treatment ratio 0.96; 90% confidence interval 0.79, 1.16). HbA1c and FPG were generally stable across both treatment periods. There was a trend towards fewer participants experiencing ≥1 hypoglycemia event at any time (24 h) and at night (00:00-05:59 h) with Gla-300 versus Gla-100. Treatment-emergent AEs, reported by 9/20 (45%) and 4/20 (20%) participants during Gla-300 and Gla-100 treatment, respectively, were unrelated to study medication.ConclusionsIn this cohort of Japanese people with T1DM, no between-treatment difference was observed in glucose variability with Gla-300 versus Gla-100, as measured by CGM. There was a trend for less hypoglycemia with Gla-300, particularly at night, versus Gla-100. Both treatments were well tolerated.FundingSanofi, Tokyo, Japan.Clinical trial registrationNCT01676233, ClinicalTrials.gov.

Project description:INTRODUCTION:OPTIMIZE evaluated the efficacy, safety and treatment satisfaction of insulin glargine 300 U/mL once daily (Gla-300 OD) in people with type 1 diabetes mellitus (T1DM) previously uncontrolled on basal insulin twice daily (BID) as part of basal-bolus therapy. METHODS:OPTIMIZE was a 28-week, prospective, interventional, single-arm phase 4 trial in adults with T1DM. At baseline, basal insulin BID treatment was switched to Gla-300 OD titrated to a fasting self-monitored blood glucose target of 4.4-7.2 mmol/L (80-130 mg/dL). The primary endpoint was the mean glycated haemoglobin (HbA1c) change from baseline to week 24. Secondary endpoints included self-monitored blood glucose, fasting-plasma glucose, hypoglycaemia and patient-reported outcomes including the Diabetes Treatment Satisfaction Questionnaire status version (DTSQs). RESULTS:Switching to Gla-300 OD significantly improved mean HbA1c (8.54% at baseline and 8.27% at week 24 [last observation carried forward, N = 94, p < 0.0001]; mean difference 0.27% [95% CI 0.15, 0.40]). There was a statistically significant decrease in fasting self-monitored blood glucose during the study (analysis of variance for repeated measures, p = 0.014; N = 72). Eight-point self-monitored blood glucose was significantly improved between baseline and week 24 for post-breakfast (p = 0.009), post-dinner (p = 0.009) and bedtime (p = 0.049) values. The study did not allow for any significant effects on confirmed and/or severe hypoglycaemia at the ≤ 3.9 mmol/L [≤ 70 mg/dL] or < 3.0 mmol/L [< 54 mg/dL] blood glucose cut-offs to be observed. Statistically significant improvements were observed in DTSQs total scores from baseline (24.1) to week 24 (29.4, p < 0.0001). CONCLUSIONS:A basal-bolus regimen including Gla-300 OD was associated with improvements in HbA1c and treatment satisfaction in people with uncontrolled T1DM previously receiving basal-bolus insulin including a basal insulin BID analogue.

Project description:IntroductionFollowing pivotal trials, real-world evidence is important to assess the impact of new drugs in everyday clinical practice. The RESTORE-1 study aimed to compare effectiveness and safety of the second-generation basal insulins (2BI), i.e., insulin glargine 300 U/ml (Gla-300) vs. degludec 100 U/ml (IDeg-100), in type 1 diabetes (T1D).MethodsRetrospective, non-inferiority, multicenter study, based on electronic medical records. All patients switching to Gla-300 or IDeg-100 from first-generation basal insulins (1BI) were 1:1 propensity score matched (PSM). Changes during 6 months in HbA1c (primary endpoint), fasting plasma glucose (FPG), body weight, and insulin doses were assessed using linear mixed models for repeated measures. Incidence rates (IR) of hypoglycemic events were assessed.ResultsOverall, 19 centers provided data on 585 patients in each PSM cohort. For both groups, statistically significant reductions in HbA1c from baseline to 6 months were documented: - 0.20%; (95% CI - 0.32; - 0.08) in the Gla-300 group and - 0.14%; (95% CI - 0.24; - 0.04) in the IDeg-100 group. The non-inferiority of Gla-300 vs. IDeg-100 was confirmed (non-inferiority margin of 0.30%; upper 95% CI at 6 months, 0.09%). No statistically significant between-group differences emerged in FPG and body weight. Dose changes of basal and short-acting insulin were small in both groups, but higher in the Gla-300 group than in the Deg-100 group (p < 0.006). Incidence rates (IR) of hypoglycemia (blood glucose ≤ 70 mg/dl and < 54 mg/dl) during the 6-month follow-up by treatment were slightly lower in the Gla-300 group than in the Deg-100 group [IR ratios 0.82 (95% CI 0.55; 1.22) and 0.83; (95% CI 0.38; 1.83), respectively]. Hypoglycemic events (blood glucose < 54 mg/dl) decreased at 6 months in both groups (p = 0.01 for Gla-300 and p < 0.001 for IDeg-100). There were no severe hypoglycemic events for Gla-300 and seven events for IDeg-100 (p = 0.02).ConclusionsSwitching from 1BI to 2BI in adults with T1D was associated with similar improvements in glycemic control and overall significant decrease in hypoglycemia, with no severe events with Gla-300. Effectiveness of both insulins was limited by under-titration.
