New insulin glargine 300 U/ml versus glargine 100 U/ml in Japanese people with type 2 diabetes using basal insulin and oral antihyperglycaemic drugs: glucose control and hypoglycaemia in a randomized controlled trial (EDITION JP 2)

Real-World Effectiveness of the Gla-300 + Cap + App Program in Adult Users Living with Type 2 Diabetes in Taiwan

INTRODUCTION

Health2Sync (H2S) is a digital health technology platform that provides coaching and titration support to patients with diabetes. The Mallya cap converts a conventional insulin pen into a smart connected device that can automatically synchronize dose values and associated timestamps (upon injection) to the H2S platform. This single-arm real-world study evaluated the effectiveness of insulin glargine 300 U/mL (Gla-300) combined with H2S and Mallya cap (Gla-300 + Cap + App program) on clinical outcomes among users with type 2 diabetes (T2D) in Taiwan.

METHODS

Adults (aged ≥ 20 years) with T2D who were registered H2S users and initiated Mallya cap for a new/existing Gla-300 regimen (identification period May 1, 2021-May 31, 2022) were included in this retrospective cohort study. Follow-up data from H2S were collected for 90 days. Glycated hemoglobin (HbA1c) change (baseline to follow-up) and HbA1c goal attainment were primary outcomes. Hypoglycemia incidence and usage metrics of Mallya cap were secondary outcomes.

RESULTS

Of 83 participants, 38.6% were new Gla-300 users. HbA1c was reduced in both new (- 2.4 [2.7] %, - 26.2 [29.5] mmol/mol) and previous Gla-300 users (- 0.5 [1.6] %, - 5.5 [17.5] mmol/mol). Reduction in HbA1c was significant (p < 0.05) in both groups. At follow-up, 43.4% of users had a reduction of > 0.5%. Mean HbA1c reductions increased numerically with higher baseline HbA1c and with longer duration of Mallya cap usage.

CONCLUSIONS

Use of digital technology within a connected ecosystem such as Gla-300 + Cap + App program could help people with type 2 diabetes to improve their glycemic condition.

Real-World Outcomes of Individualized Targeted Therapy with Insulin Glargine 300 Units/mL in Insulin-Naïve Korean People with Type 2 Diabetes: TOBE Study

INTRODUCTION

The TOujeo BEyond glucose control (TOBE) study evaluated clinical outcomes with insulin glargine 300 units/mL (Gla-300) in insulin-naïve Korean people with type 2 diabetes mellitus (T2DM) in a real-world setting.

METHODS

This 24-week, prospective, non-interventional, multicenter, open-label, single-arm, observational study included adults aged ≥ 20 years with T2DM suboptimally controlled with oral hypoglycemic agents and/or glucagon-like peptide 1 receptor agonists who require basal insulin. Eligible participants were assigned to either general target glycated hemoglobin (HbA1c < 7%) or individualized target groups as per physician's discretion considering guidelines and participants' characteristics. The primary endpoint was the proportion of participants achieving the HbA1c target (individualized or general) at 24 weeks.

RESULTS

Among 369 participants, 19.5% (72/369) of participants achieved the HbA1c target at week 24; 37.5% (33/88) in the individualized and 13.9% (39/281) in the general target group. In both target groups, similar reductions in fasting plasma glucose and body weight were observed, with low incidence of hypoglycemia, and T2DM duration was significantly shorter in participants who did versus those who did not achieve the target HbA1c (individualized target group: 9.6 ± 8.0 versus 13.1 ± 8.4 years, P = 0.0454; general target group: 10.2 ± 8.6 versus 12.8 ± 7.4 years, P = 0.0378).

CONCLUSIONS

This study showed that initiation of insulin therapy with Gla-300 in people with T2DM using an individualized approach is more effective in achieving an HbA1c target. Moreover, earlier initiation of insulin therapy in people with suboptimally controlled T2DM may increase the success rate of glycemic control. A graphical abstract is available with this article.

Current usage of long-acting insulin analogs in patients with type 2 diabetes mellitus

INTRODUCTION

Insulin treatment is fundamental to diabetes management. Basal insulin therapy reduces intraday glycemic fluctuations upon reaching a steady state. Besides better blood glucose regulation and achieving target HbA1c values in patients, it also offers protection from diabetes complications. In this review, we aimed to compare basal-acting insulins in light of the literature.

AREAS COVERED

We reviewed current evidence related to diabetes treatment with basal insulins. This includes discussions on clinical trials and meta-analyses concerning first and second-generation ultra-long-acting basal insulins. Treatment indications for long-acting basal insulins, which have shown benefits and are considered superior or comparable to others in the literature, are derived from current clinical studies and meta-analyses, which form the basis of the recommendations in this review.

EXPERT OPINION

First and second-generation basal insulins do not show much superiority over each other in terms of blood glucose regulation and reaching the target HbA1c. However, second-generation basal insulins cause fewer hypoglycemic events. We recommend using the appropriate basal insulin in patient-based, individualized treatments. Basal insulin Icodec may become more widely used over time, owing to its association with less hypoglycemia and a reduction in the number of injections.

Insulin Glargine in Type 1 Diabetes Mellitus: A Review of Clinical Trials and Real-world Evidence Across Two Decades

BACKGROUND

Over the past two decades, insulin glargine 100 U/mL (Gla-100) has emerged as the "standard of care" basal insulin for the management of type 1 diabetes mellitus (T1DM). Both formulations, insulin glargine 100 U/mL (Gla-100) and glargine 300 U/mL (Gla- 300) have been extensively studied against various comparator basal insulins across various clinical and real-world studies. In this comprehensive article, we reviewed the evidence on both insulin glargine formulations in T1DM across clinical trials and real-world studies.

METHODS

Evidence in T1DM for Gla-100 and Gla-300 since their approvals in 2000 and 2015, respectively, were reviewed.

RESULTS

Gla-100 when compared to the second-generation basal insulins, Gla-300 and IDeg-100, demonstrated a comparable risk of overall hypoglycemia, but the risk of nocturnal hypoglycemia was higher with Gla-100. Additional benefits of Gla-300 over Gla-100 include a prolonged (>24- hours) duration of action, a more stable glucose-lowering profile, improved treatment satisfaction, and greater flexibility in the dose administration timing.

CONCLUSION

Both glargine formulations are largely comparable to other basal insulins in terms of glucose-lowering properties in T1DM. Further, risk of hypoglycemia is lower with Gla-100 than Neutral Protamine Hagedorn but comparable to insulin detemir.

Comparative clinical efficacy and safety of insulin glargine 300 U/ml (Toujeo) versus insulin glargine 100 U/ml in type 2 diabetes and type 1 diabetes: A systematic literature review and meta-analysis

AIM

To compare the clinical efficacy and safety of glargine-U100 (Lantus/Gla-100) with glargine-U300 (Toujeo/Gla-300) in adult patients with type 2 diabetes (T2D) and type 1 diabetes (T1D).

MATERIALS AND METHODS

A literature search on Gla-300/Gla-100 in diabetes management was conducted using the MEDLINE/Embase/Cochrane databases from inception to 10 January 2021. Eligible studies considered for inclusion were parallel-design, randomized controlled trials (RCTs). The Cochrane risk-of-bias tool was used to evaluate the quality of the included studies. The random-effects model was applied for interpretation of the results.

RESULTS

Of 5348 records screened, 592 were assessed for eligibility and 15 RCTs were considered for data extraction and meta-analysis (T2D [N = 10; n = 7082]; T1D [N = 5; n = 2222]). In patients with T1D, all safety parameters were comparable between Gla-100 and Gla-300. In T2D, statistically significant differences were observed in favour of Gla-300 over Gla-100 for nocturnal and total hypoglycaemia. For efficacy parameters, a statistically and clinically significant difference favouring Gla-100 in basal insulin dose requirement was observed for both T2D and T1D. Change in HbA1c showed a statistically but not clinically significant reduction with Gla-100 compared with Gla-300 in T1D. Statistically significant but clinically less relevant differences favoured Gla-300 for control of body weight in T1D and T2D and Gla-100 for fasting blood glucose in T2D.

CONCLUSIONS

Gla-100 and Gla-300 had comparable efficacy and safety profiles in both T1D and T2D populations. Gla-300 showed a lower risk of nocturnal and total hypoglycaemia, significant in insulin-experienced/exposed patients with T2D. Patients on Gla-300 required significantly more units of insulin daily than the Gla-100 group to achieve equivalent efficacy.

The economic value of insulin glargine 300 U/mL (Gla-300) in people ≥18 years of age with type 2 diabetes mellitus: a value-based economic model from a U.S. payer perspective

AIMS

This study aimed to evaluate the value and affordability of insulin glargine 300 U/mL (Gla-300) in a budget impact model from a United States (U.S.) payer perspective by leveraging recent real-world evidence (RWE) studies and incorporating the recent insulin price caps where applicable.

MATERIALS AND METHODS

An economic model for a hypothetical one million U.S. health-plan population was developed to assess the budgetary impact of therapeutic interchanges in either direction between the two long- and longer-acting basal insulins (BIs) for patients with type 2 diabetes over a three-year model horizon. The utilization of long-acting BIs, longer-acting BIs, biosimilar BIs, and insulin degludec (IDeg-100) were informed by IQVIA data and internal forecasting at Sanofi. The DELIVER-2 and DELIVER-naïve studies provided healthcare resource utilization (HCRU) parameters. In the model base case, 24% of patients switched from long-acting BIs to insulin glargine biosimilars, IDeg-100, and other longer-acting BIs (Gla-300) by projected year 3.

RESULTS

The base case total costs were $10,145 per patient per year (PPPY) in year 3 for the cumulative population. When all patients switched to Gla-300, the total costs in year 3 were $8,799, reflecting a net savings of -$660 PPPY compared to the budget increase of $686 PPPY in the base case. However, the longer-acting to long-acting BIs reversal scenario demonstrated a budgetary decrease of $676 PPPY over the model horizon. The reduction in incremental PPPY cost of $93 was observed using net drug costs rather than wholesale acquisition costs (WAC).

LIMITATIONS

The market shares for years 1-3 were based on expectations supported by the clinicians' expert opinions and were not obtained from real-world data.

CONCLUSIONS

The economic value of increased utilization of Gla-300 was driven by the reduction in HCRU, costs and market shares assumptions. Budgetary reductions were achieved by switching patients from long-acting BIs to Gla-300.

Improved glycaemic control and weight benefit with iGlarLixi versus insulin glargine 100 U/mL in Chinese people with type 2 diabetes advancing their therapy from basal insulin plus oral antihyperglycaemic drugs: Results from the LixiLan-L-CN randomized controlled trial

AIMS

To evaluate the efficacy and safety of iGlarLixi compared with iGlar in Chinese adults with type 2 diabetes advancing therapy from basal insulin ± oral antihyperglycaemic drugs.

MATERIALS AND METHODS

LixiLan-L-CN (NCT03798080) was a 30-week randomized, active-controlled, open-label, parallel-group, multicentre study. Participants were randomized 1:1 to iGlarLixi or iGlar. The primary objective was to show the superiority of iGlarLixi over iGlar in glycated haemoglobin (HbA1c) change from baseline to Week 30.

RESULTS

In total, 426 participants were randomized to iGlarLixi (n = 212) or iGlar (n = 214). Mean age was 58 years, 67% had a body mass index ≥24 kg/m² , corresponding to overweight/obesity, and the mean diabetes duration was 12.3 years. From mean baseline HbA1c of 8.1% in both groups, greater decreases were seen with iGlarLixi versus iGlar [least squares mean difference: -0.7 (95% confidence interval: -0.9, -0.6)%; p < .0001] to final HbA1c of 6.7% and 7.4%, respectively. HbA1c <7.0% achievement was greater with iGlarLixi (63.3%) versus iGlar (29.9%; p < .0001). Mean body weight decreased with iGlarLixi and increased with iGlar [least squares mean difference: -0.9 (95% confidence interval: -1.4, -0.5) kg; p = .0001]. Hypoglycaemia incidence was similar between groups. Few gastrointestinal adverse events occurred (rated mild/moderate) with a slightly higher incidence with iGlarLixi than iGlar.

CONCLUSIONS

iGlarLixi provided better glycaemic control and facilitated more participants to reach glycaemic targets alongside beneficial effects on body weight, no additional risk of hypoglycaemia, and few gastrointestinal AEs, supporting iGlarLixi use as an efficacious and well tolerated therapy option in Chinese people with long-standing T2D advancing therapy from basal insulin.

Twenty Years of Insulin Gla-100: A Systematic Evaluation of Its Efficacy and Safety in Type 2 Diabetes Mellitus

INTRODUCTION

This systematic review aims to present the current evidence base with respect to the initiation and intensification of insulin therapy with glargine 100 U/mL (Gla-100) compared to other insulins in people with type 2 diabetes mellitus (T2DM).

METHODS

A systematic literature search of PubMed (MEDLINE), EMBASE, and the Cochrane Central Register of controlled clinical trials databases was performed to identify studies published up to September 30, 2020 that compared the effects of Gla-100 to that of other insulin regimens in people with T2DM. Relevant information pertaining to the predefined outcomes of interest was extracted. Glycated hemoglobin (HbA1c) change and response rates along with overall hypoglycemia incidence were the primary efficacy and safety outcomes of interest.

RESULTS

Seventy-nine studies (63 interventional and 16 non-interventional) in which Gla-100 was either initiated in previously insulin-naïve patients (n = 57) or used in an intensified regimen (n = 22) were identified and evaluated. In insulin-naïve patients, most studies demonstrated that Gla-100 was significantly better compared with premixed insulins and similar compared with neutral protamine Hagedorn (NPH) insulin, second-generation basal insulins, co-formulations, and other first-generation basal insulins in terms of the primary efficacy parameters. Overall hypoglycemia risk with Gla-100 was significantly lower compared with NPH, premixed, coformulation, and other first-generation basal insulins and significantly higher compared with second-generation basal insulins. In studies with intensified regimens, efficacy outcomes with Gla-100 were significantly better compared with insulin detemir (IDet); similar compared with NPH, second-generation basal insulins, co-formulations; and with premixed insulins. In these studies, overall hypoglycemia risk with Gla-100 was significantly lower compared with IDet and comparable to NPH, premixed insulins, co-formulations, and second-generation basal insulins. In addition, most intensification studies also revealed a significantly lower risk of nocturnal hypoglycemia with Gla-100-based regimens versus NPH and premixed insulins and a significantly greater risk compared to second-generation basal insulins.

CONCLUSIONS

The evidence presented in this review suggests that Gla-100 is an effective option for both insulin initiation and intensification strategies used in the management of T2DM.

Clinical course of different long-acting insulin therapies-glargine U100, U300, degludec, and insulin degludec/insulin aspart-among Japanese patients with type 2 diabetes: a multicenter retrospective observational study (JDDM65 study)

This study aimed to retrospectively compare the clinical efficacy of different types of long-acting insulin therapies-glargine U100, glargine U300, degludec, and insulin degludec/insulin aspart-among Japanese patients with type 2 diabetes after insulin use was initiated in an outpatient setting. The study consisted of 822 insulin-naïve patients in Japan who started using long-acting insulin for treatment of type 2 diabetes and continued for over 12 months. In addition, the impact of insulin type on insulin withdrawal was investigated by dividing the participants into two groups: those who achieved insulin withdrawal and those who did not, during the 12-month observation period based on a Cox proportional hazards model. As a result, HbA1c was decreased, and BMI was increased in all participants regardless of the insulin type used. A total of 185 participants succeeded in insulin withdrawal. After adjustment was made for several confounders, the positive determinant factors for withdrawal were short duration of diabetes and the choice of IDegAsp when compared with Gla100; the negative determinant factor was use of insulin secretagogues at the start of the study. In conclusion, all long-acting insulins were a powerful tool for treatment of type 2 diabetes, and patients with short duration of diabetes and/or no usage of insulin secretagogues resulted in favorable outcomes in terms of insulin withdrawal within a year in an outpatient setting. In addition, insulin degludec/insulin aspart was found to possibly be a better choice for treatment when it was compared with glargine U100 among the four types of insulin.

Evaluation of Patient Reported Satisfaction and Clinical Efficacy of Insulin Glargine 300 U/mL Versus 100 U/mL in Patients With Type 1 Diabetes Using Flash Glucose Monitoring System

Background and Aims:

To analyze patient-reported satisfaction and clinical effectiveness of concentrated insulin glargine 300 U/mL (Gla-300) among patients with type 1 diabetes (T1D) using a flash glucose monitoring (FGM) system.

Methods:

This comparative study was conducted among 86 patients with T1D (aged 14-40 years), who were treated with Glargine 100 U/mL (Gla-100) and switched to Gla-300 at day 1 (baseline). The following data were collected from each patient: demographic information, clinical parameters, and glycemic control markers. All patients completed the Diabetes Treatment Satisfaction Questionnaire (Arabic version), first at baseline and then after 12 weeks. A comparison was done for all the data recorded at baseline (on Gla-100) and after 12 weeks (on Gla-300) and subjected to analysis.

Results:

Compared to patients treated with Gla-100, significant improvements were observed in the Gla-300 group, in terms of the ambulatory glucose profile (AGP) markers, such as percentage of time spent within the target range of the glucose levels (70-180 mg/dL) (P = .037), percentage which fell below the target (<70 mg/dL) (P = .027), and percentage of time spent (<54 mg/dL) (P = .043). Compared to Gla-100, patients treated with Gla-300 experienced significant improvements in the current treatment satisfactions (P = .047), convenient finding treatment recently (P = .034), and flexible finding treatment recently (P = .041), recommend the current treatment (P = .042) and satisfied to continue the current treatment (P = .035).

Conclusion:

Compared to the patients on Gla-100, patients treated with Gla-300 exhibited significant improvements in the AGP markers and degree of treatment satisfaction.

Insulin glargine 300 U/ml for the treatment of feline diabetes mellitus

OBJECTIVES

The study aimed to evaluate the efficacy and safety of insulin glargine 300 U/ml (IGla-U300) in cats with variable duration of diabetes mellitus (DM).

METHODS

Thirteen client-owned cats with DM completed a prospective clinical trial. Four cats were highly suspected of hypersomatotropism and excluded from the insulin efficacy evaluation. All cats were treated with IGla-U300 SC at a starting dosage of 0.5 U/kg q12h and fed with a low carbohydrate diet. Cats were monitored for 8 weeks with a once-weekly at-home 16 h blood glucose curve (BGC) and a questionnaire evaluating the presence of DM-related clinical signs. In-clinic evaluations, including serum fructosamine measurement, were scheduled within 3 days of the first, third, sixth and eighth BGC. Glycemic variability was assessed by calculating the SD of each BGC.

RESULTS

Excluding four cats suspected of hypersomatotropism, at the time of the eighth BGC, improved or absent polyuria, polydipsia, polyphagia, weight loss, lethargy and improved or normal general demeanor were reported in 8/9 (88%), 8/9 (88%), 7/9 (77%), 7/9 (77%), 7/9 (77%) and 8/9 (88%) cats, respectively. Two cats achieved remission after 29 and 53 days. Another two cats went into remission after the end of the study (days 82 and 96). All cats that achieved remission were newly diagnosed diabetics. Median (range) serum fructosamine concentration significantly decreased when comparing the time of enrollment (604 [457-683] µmol/l) with the eighth week of treatment (366 [220-738] µmol/l) (P = 0.02). In all 13 cats, biochemical hypoglycemia (blood glucose <60 mg/dl; <3.3 mmol/l) was detected in 13/104 (12.5%) BGCs, while clinical signs suggesting hypoglycemic episodes were not reported. Glycemic variability was significantly lower at the fifth BGC when comparing cats that achieved remission with cats that did not achieve remission (P = 0.02).

CONCLUSIONS AND RELEVANCE

IGla-U300 seems effective and safe for the treatment of feline diabetes, but more long- term and comparative clinical trials are needed.

Clinical outcomes in high‐hypoglycaemia‐risk patients with type 2 diabetes switching to insulin glargine 300 U/mL versus a first‐generation basal insulin analogue in the United States : Results from the DELIVER High Risk real‐world study

Aims

To compare 12‐month clinical effectiveness of insulin glargine 300 units/mL (Gla‐300) versus first‐generation basal insulin analogues (BIAs) (insulin glargine 100 units/mL [Gla‐100] or insulin detemir [IDet]) in patients with type 2 diabetes (T2D) who were at high risk of hypoglycaemia and switched from one BIA to a different one (Gla‐300 or Gla‐100/IDet) in a real‐world setting.

Methods

DELIVER High Risk was a retrospective observational cohort study of 2550 patients with T2D who switched BIA to Gla‐300 (Gla‐300 switchers) and were propensity score‐matched (1:1) to patients who switched to Gla‐100 or IDet (Gla‐100/IDet switchers). Outcomes were change in glycated haemoglobin A1c (HbA1c), attainment of HbA1c goals (<7% and <8%), and incidence and event rates of hypoglycaemia (all‐hypoglycaemia and hypoglycaemia associated with an inpatient/emergency department [ED] contact).

Results

HbA1c reductions were similar following switching to Gla‐300 or Gla‐100/IDet (−0.51% vs. −0.53%; p = .67), and patients showed similar attainment of HbA1c goals. Patients in both cohorts had comparable all‐hypoglycaemia incidence and event rates. However, the Gla‐300 switcher cohort had a significantly lower risk of inpatient/ED‐associated hypoglycaemia (adjusted odds ratio: 0.73, 95% confidence interval: 0.60–0.89; p = .002) and experienced significantly fewer inpatient/ED‐associated hypoglycaemic events (0.21 vs. 0.33 events per patient per year; p < .001).

Conclusion

In patients with T2D at high risk of hypoglycaemia, switching to Gla‐300 or Gla‐100/IDet achieved similar HbA1c reductions and glycaemic goal attainment, but Gla‐300 switchers had a significantly lower risk of hypoglycaemia associated with an inpatient/ED contact during 12 months after switching.

Efficacy and Safety of Self-Titration Algorithms of Insulin Glargine 300 units/mL in Individuals with Uncontrolled Type 2 Diabetes Mellitus (The Korean TITRATION Study): A Randomized Controlled Trial

BACKGROUND

To compare the efficacy and safety of two insulin self-titration algorithms, Implementing New Strategies with Insulin Glargine for Hyperglycemia Treatment (INSIGHT) and EDITION, for insulin glargine 300 units/mL (Gla-300) in Korean individuals with uncontrolled type 2 diabetes mellitus (T2DM).

METHODS

In a 12-week, randomized, open-label trial, individuals with uncontrolled T2DM requiring basal insulin were randomized to either the INSIGHT (adjusted by 1 unit/day) or EDITION (adjusted by 3 units/week) algorithm to achieve a fasting self-monitoring of blood glucose (SMBG) in the range of 4.4 to 5.6 mmol/L. The primary outcome was the proportion of individuals achieving a fasting SMBG ≤5.6 mmol/L without noct urnal hypoglycemia at week 12.

RESULTS

Of 129 individuals (age, 64.1±9.5 years; 66 [51.2%] women), 65 and 64 were randomized to the INSIGHT and EDITION algorithms, respectively. The primary outcome of achievement was comparable between the two groups (24.6% vs. 23.4%, P=0.876). Compared with the EDITION group, the INSIGHT group had a greater reduction in 7-point SMBG but a similar decrease in fasting plasma glucose and glycosylated hemoglobin. The increment of total daily insulin dose was significantly higher in the INSIGHT group than in the EDITION group (between-group difference: 5.8±2.7 units/day, P=0.033). However, body weight was significantly increased only in the EDITION group (0.6±2.4 kg, P=0.038). There was no difference in the occurrence of hypoglycemia between the two groups. Patient satisfaction was significantly increased in the INSIGHT group (P=0.014).

CONCLUSION

The self-titration of Gla-300 using the INSIGHT algorithm was effective and safe compared with that using the EDITION algorithm in Korean individuals with uncontrolled T2DM (ClinicalTrials.gov number: NCT03406663).

Effect of Newer Long-Acting Insulins on Hypoglycemia and Fracture Risk Among People with Diabetes: A Systematic Review

PURPOSE OF REVIEW

To investigate the effect of newer long-acting insulins on the risk of hypoglycemic episodes and fractures in people with diabetes.

RECENT FINDINGS

Hypoglycemic episodes are the critical limiting factor in glycemic management due to a deteriorating effect on quality of life. Hypoglycemia may in severe cases lead to unconsciousness and thus fractures. Newer long-acting insulins may result in more stable blood glucose levels, less hypoglycemic episodes, and reduced risk of fractures. Use of insulin increases risk of hypoglycemic episodes, and hypoglycemic episodes increase risk of fractures plausible due to falls. Newer ultra-long-acting insulins reduce risk of hypoglycemic episodes compared to older alternatives, and they are thus promising for reducing fracture risk. However, more studies are needed to determine whether these new insulins reduce risk of fractures.

Efficacy and safety of different basal and prandial insulin analogues for the treatment of type 2 diabetes: a network meta-analysis of randomized controlled trials

AIM

The aim of the present network meta-analysis is to assess the efficacy and safety across different long and short-acting analogs for the treatment of type 2 diabetes.

METHODS

A PubMed, EMBASE, and Cochrane Central Register of Controlled Trials databases search (20th May, 2020) for all trials with a duration ≥24 weeks comparing an analogue with another or human insulin was performed. Indirect comparisons were performed by NMA choosing glargine U100 and human regular insulin, as the reference for long- and short-acting analogues, respectively. Primary endpoints were HbA1c at 24, 52, and 104 weeks. The weighted difference in means (WDM) and Mantel-Haenzel Odds Ratio [MH-OR] with 95% Confidence Intervals (CI) were calculated for categorical and continuous variables, respectively.

RESULTS

Fifty trials (n = 43) and 7 for basal and prandial analogues, respectively, enrolling 25,554 and 3184 patients with type 2 and 1 diabetes, respectively, were included. At NMA, detemir was less effective than glargine U-100 at 52 weeks. A significant reduction of 24-week HbA1c (WMD [IC]: -0.10 [-0.17, -0.03]%); and risk of total (MH-OR [IC]: 0.80 [0.70, 0.91]), and nocturnal hypoglycemia (MH-OR [IC]: 0.57 [0.45, 0.73]) was observed for basal analogues versus NPH insulin. At NMA, glargine U300 and degludec were associated with a significant reduction in the risk of nocturnal hypoglycemia. No significant differences across different short-acting insulin were observed.

CONCLUSIONS

This paper supports the use of long-acting analogues, rather than NPH insulin, as basal insulin for the treatment of type 2 diabetes, without any preferences for any individual long-acting analogue over the others. The evidence on short acting analogues is limited.

Clinical Characteristics of Withdrawal of Basal Insulin Therapy Among Japanese Patients with Type 2 Diabetes: A Multicenter Retrospective Observational Study

INTRODUCTION

This study aimed to examine retrospectively the clinical backgrounds of Japanese patients with type 2 diabetes (T2D) who successfully withdrew from insulin use after being started on basal insulin in an outpatient setting.

METHODS

The study population comprised 376 insulin-naïve patients who were started on basal insulin (glargine U100, glargine U300, or degludec) for the management of T2D and followed the treatment regimen for at least 6 months in 13 institutions in Japan. The clinical courses of the study participants were compared based on outpatient clinic medical records for the three different types of basal insulin prescribed by categorizing the participants into two groups retrospectively: those who successfully withdrew from insulin therapy and those who did not, during a 6-month observation period. The clinical determinants for insulin withdrawal were assessed using a Cox proportional hazard model.

RESULTS

Glycated hemoglobin was improved in all participants regardless of basal insulin type. Of the 376 study participants, 61 successfully withdrew from basal insulin therapy. After adjustment was made for several confounders, the positive determinant factors for successful withdrawal of insulin were short duration of diabetes and high body mass index at the start of study, and the negative determinant factor was use of insulin secretagogues at the start. The types of basal insulin used by the study participants were not significant determinants of successful insulin withdrawal in this study.

CONCLUSIONS

Use of basal insulin is a powerful option for the treatment of T2D. In patients with high BMI and/or short duration of diabetes, short-term insulin therapy is a promising strategy for the treatment of T2D before the initiation of insulin secretagogues, since such patients have the potential to successfully withdraw from basal insulin use even in an outpatient setting.

Comparison of insulin glargine 300 U/mL versus glargine 100 U/mL on glycemic control and hypoglycemic events in East Asian patients with type 2 diabetes: A Patient-level meta-analysis of phase 3 studies

AIMS

To evaluate efficacy and safety of Gla-300 with Gla-100 in a patient-level meta-analysis among large East Asian patients with type 2 diabetes mellitus (T2DM).

METHODS

A patient level meta-analysis of three EDITION studies with similar design and endpoints were conducted over 6-months treatment period. The analysis included 547 patients treated with Gla-300 and 348 patients treated with Gla-100.

RESULTS

Over 6-month treatment period, mean change in HbA1c was similar for Gla-300 [Least square (LS) mean, (SE): -1.13 (0.05) % and Gla-100: -1.14 (0.05) %], showing non-inferiority of Gla-300 to Gla-100 (LS mean difference: 0.02%, 95% CI: -0.08 to 0.11). Gla-300 was associated with reduced risk of hypoglycemic event (confirmed ≤ 3.9 mmol/L or severe) vs Gla-100 at any time of day or at night (00:00-05:59 h). The event rates of hypoglycemia were consistently lower with Gla-300 than Gla-100. Severe hypoglycemia was rare in both treatment groups. Weight gain was minimal in both treatment groups.

CONCLUSION

Gla-300 provides comparable glycemic control to Gla-100 in East Asian patients with broad clinical spectrum of T2DM, with consistently less hypoglycemia at any time of the day and night.

Comparative clinical outcomes of insulin degludec and insulin glargine 300 U/mL after switching from other basal insulins in real-world patients with type 1 and type 2 diabetes

Aims/Introduction

To evaluate and compare the efficacy of insulin degludec (IDeg) and insulin glargine 300 U/mL (Gla300) 6 months after switching from other basal insulins by assessing the changes in glycated hemoglobin (HbA1c), body mass index (BMI), and insulin doses in patients with type 1 and type 2 diabetes in a real‐world clinical setting.

Materials and Methods

A total of 307 patients with type 1 diabetes and 294 patients with type 2 diabetes with HbA1c >7.0% were studied. Adjusted mean changes in HbA1c, BMI, and insulin doses were compared between IDeg (IDeg group) and Gla300 (Gla300 group) switchers. Multivariable logistic regression analyses were carried out to examine whether the IDeg or Gla300 group was associated with HbA1c or insulin dose reduction and BMI gain.

Results

HbA1c was significantly decreased in both the IDeg and Gla300 groups. Adjusted mean changes in HbA1c (approximately −0.3% and −0.5% in type 1 diabetes and type 2 diabetes patients, respectively) and BMI were similar between both groups. The mean change in insulin dose was slightly larger for dose reduction in the IDeg group than in the Gla300 group. Multivariable logistic regression models showed that the IDeg group was significantly associated with insulin dose reduction after adjusting for basal insulin type, insulin dose, and number of basal insulin injections at baseline and other confounding factors.

Conclusions

The current study suggested that IDeg and Gla300 have similar effects in reducing HbA1c and gaining BMI after switching from other basal insulins in Japanese patients with type 1 diabetes and type 2 diabetes. IDeg selection was associated with insulin dose reduction.

Equipotency of insulin glargine 300 and 100 U/mL with intravenous dosing but differential bioavailability with subcutaneous dosing in dogs

AIMS

Insulin glargine 300 U/mL (Gla-300) contains the same units versus glargine 100 U/mL (Gla-100) in three-fold lower volume, and higher subcutaneous (SC) doses are required in people with diabetes. To investigate blood glucose (BG) lowering potency, Gla-300 and Gla-100 were compared after intravenous (IV, for 4 h) and SC (for 24 h) injection in healthy Beagle dogs.

MATERIALS AND METHODS

The dose of 0.15 U/kg Gla-300 and Gla-100 was injected IV in 12 dogs. BG, C-peptide, glucagon and the active metabolite 21A-Gly-human insulin (M1; liquid chromatography-tandem mass spectrometry method) were measured. Twelve other dogs were studied after SC injection of 0.3 U/kg Gla-300 and Gla-100.

RESULTS

After IV injection, Gla-300 and Gla-100 were equally potent [BG_AUC_{0-4 h} ratio 1.01 (95% confidence interval, 0.94; 1.09)]. After SC injection, BG decreased slower and less with Gla-300. Similar metabolism of Gla-300 and Gla-100 to M1 occurred with IV dosing [M1_AUC_{0-1 h} ratio 0.99 (95% confidence interval, 0.82; 1.22)], but with SC dosing M1_C_max and AUC_0-24h were 44% and 17% lower; mean residency time and bioavailability were 32% longer and 50% lower, with Gla-300.

CONCLUSIONS

IV Gla-300 and Gla-100 have the equivalent of BG-lowering potency and M1 metabolism. SC Gla-300 has lower M1 bioavailability with a reduced BG-lowering effect and need for greater doses versus Gla-100.

A pragmatic randomized clinical trial of insulin glargine 300 U/mL vs first-generation basal insulin analogues in insulin-naïve adults with type 2 diabetes: 6-month outcomes of the ACHIEVE Control study

AIMS

To compare the safety and efficacy of insulin glargine 300 U/mL (Gla-300) versus first-generation standard-of-care basal insulin analogues (SOC-BI; insulin glargine 100 U/mL or insulin detemir) at 6 months.

METHODS

In the 12-month, open-label, multicentre, randomized, pragmatic ACHIEVE Control trial, insulin-naïve adults with type 2 diabetes (T2D) and glycated haemoglobin (HbA1c) 64 to 97 mmol/mol (8.0%-11.0%) after ≥1 year of treatment with ≥2 diabetes medications were randomized to Gla-300 or SOC-BI. The composite primary endpoint, evaluated at 6 months, was the proportion of participants achieving individualized HbA1c targets per Healthcare Effectiveness Data and Information Set (HEDIS) criteria without documented symptomatic (blood glucose ≤3.9 mmol/L [≤70 mg/dL]) or severe hypoglycaemia at any time of the day at 6 months.

RESULTS

Of 1651 and 1653 participants randomized to Gla-300 and SOC-BI, respectively, 31.3% and 27.9% achieved the composite primary endpoint at 6 months (odds ratio [OR] 1.19, 95% confidence interval [CI] 1.01-1.39; P = 0.03 for superiority); 78.4% and 75.3% had no documented symptomatic or severe hypoglycaemia (OR 1.19, 95% CI 1.01-1.41). Changes from baseline to month 6 in HbA1c, fasting plasma glucose, weight, and BI analogue dose were similar between groups.

CONCLUSIONS

Among insulin-naïve adults with poorly controlled T2D, Gla-300 was associated with a statistically significantly higher proportion of participants achieving individualized HEDIS HbA1c targets without documented symptomatic or severe hypoglycaemia (vs SOC-BI) in a real-life population managed in a usual-care setting. The ACHIEVE Control study results add value to treatment decisions and options for patients, healthcare providers, payers and decision makers.

The Safety and Efficacy of Second-Generation Basal Insulin Analogues in Adults with Type 2 Diabetes at Risk of Hypoglycemia and Use in Other Special Populations: A Narrative Review

Hypoglycemia is a major barrier impeding glycemic control in persons with type 2 diabetes mellitus and creates a substantial burden on the healthcare system. Certain populations that require special attention, such as older adults and individuals with renal impairment, a longer duration of diabetes or those who have experienced prior hypoglycemia, may be at a higher risk of hypoglycemia, particularly with insulin treatment. Second-generation basal insulin analogues (insulin glargine 300 U/mL and degludec) have demonstrated reductions in hypoglycemia compared with insulin glargine 100 U/mL although evidence of this benefit across specific populations is less clear. In this review we summarize the literature with respect to the efficacy and safety data for second-generation basal insulin analogues in adults with type 2 diabetes mellitus who are at risk of hypoglycemia or who require special attention. Randomized controlled trials, meta-analyses and real-world evidence demonstrate that the use of second-generation basal insulin analogues is associated with less hypoglycemia compared with insulin glargine 100 U/mL without compromising glycated hemoglobin control. A reduced risk of hypoglycemia with second-generation basal insulin analogues was evident in older adults and in individuals with obesity, renal impairment, a history of cardiovascular disease or a long duration of insulin use. Further studies are needed in other populations, including those with more severe renal impairment or hepatic dysfunction, the hospitalized population and those with cognitive impairment. Overall, less hypoglycemia associated with second-generation basal insulin analogues may help reduce barriers for insulin use, improve adherence and offset the costs of hypoglycemia-related healthcare resource utilization.

Using 2nd generation basal insulins in type 2 diabetes: Costs and savings in a comparative economic analysis in Italy, based on the BRIGHT study

BACKGROUND AND AIMS

To evaluate the economic impact of using 2nd generation basal insulin analogs, Glargine 300 Units/ml (Gla-300) vs Degludec 100 Units/ml (IDeg-100), in patients with type 2 diabetes (T2D).

METHODS AND RESULTS

An economic analysis was conducted using findings from the BRIGHT study (the first controlled, head-to-head study comparing Gla-300 vs IDeg-100), and costs for the Italian National Healthcare Service (NHS). A cost-minimization analysis (CMA) and a budget impact analysis (BIA) were conducted. Only pharmacological costs were included in the analysis. The CMA estimated patient treatment costs at 24 weeks and 1 year; the BIA assessed the economic impact of treating the overall Italian population of T2D insulin-naïve patients, who initiated insulin treatment during the period September 2017-August 2018 (N = 55 318). In the BIA, four different scenarios were compared: i) all patients receive IDeg-100 (Scenario A); ii) 61% of patients receive Gla-300, 39% IDeg-100 (Scenario B); iii) 80% of patients receive Gla-300, 20% IDeg-100 (Scenario C); iv) all patients treated with Gla-300 (Scenario D). The average treatment costs per patient were lower with Gla-300 vs IDeg-100 (at 24 weeks: €129 vs €161; at 1 year: €324 vs €409, respectively). Results of the BIA showed that comparing Scenario D vs Scenario A, total savings would amount to €1.76 million at 24 weeks, €4.73 million at 1 year, €5.53 million at 2 years.

CONCLUSION

A larger use of Gla-300 vs IDeg-100 for the treatment of T2D patients would lead to a relevant reduction of therapy costs in Italy.

Insulin glargine 300 U/mL and insulin degludec: A review of the current evidence comparing these two second-generation basal insulin analogues

For most people with type 2 diabetes (T2D), treatment intensification with the addition of basal insulin therapy is required to maintain glycaemic control. However, this often does not happen in real-life practice promoting the development of long-term diabetes-related complications. The second-generation basal insulin analogues glargine 300 U/mL (Gla-300) and degludec (IDeg) provide pharmacokinetic and pharmacodynamic improvements that may allow them to be more effective in appropriately managing diabetes compared with first-generation basal insulin analogues. Both Gla-300 and IDeg have been extensively studied vs the first-generation basal insulin glargine 100 U/mL, demonstrating comparable efficacy in terms of glycaemic control, and a lower risk of hypoglycaemia. The BRIGHT randomized controlled trial is the first direct comparison of the efficacy and safety profiles of Gla-300 and IDeg in patients with T2D. Moreover, real-world data have been used to assess the effectiveness of these basal insulins during routine clinical practice. Further research is required to determine if the properties of Gla-300 and IDeg may lead to improvements in healthcare-related costs and the quality of life of patients, which are important factors for informing clinical decisions.

Reduced Hypoglycemia Risk in Type 2 Diabetes Patients Switched to/Initiating Insulin Glargine 300 vs 100 U/ml: A European Real-World Study

INTRODUCTION

Randomized controlled trials and real-world data from the USA have shown similar glycemic control with insulin glargine 300 U/ml (Gla-300) and insulin glargine 100 U/ml (Gla-100) and reduced hypoglycemia risk with Gla-300. This real-world study describes the efficacy and safety of Gla-300 and Gla-100 in patients with type 2 diabetes (T2D) in France, Spain, and Germany.

METHODS

This retrospective chart review analysis used anonymized data for adults with T2D switching basal insulin analog (BIA) therapy to Gla-300 or Gla-100, or insulin-naïve patients initiating Gla-300 or Gla-100. Outcomes included change from baseline to 6-month follow-up in glycated hemoglobin A1c (A1C), total and severe hypoglycemia incidences and events, insulin dose, and reasons for BIA choice.

RESULTS

Six hundred sixty-five physicians (33.8% Spain, 31.7% France, 34.4% Germany) provided chart data for patients switching to Gla-300 (n = 679) or Gla-100 (n = 429) or initiating Gla-300 (n = 719) or Gla-100 (n = 711). After adjustment for baseline characteristics, A1C reductions from baseline were similar for patients switching to Gla-300 or Gla-100 (- 0.87% vs. - 0.93%; p = 0.326) while those switched to Gla-300 vs. Gla-100 had a significantly greater mean reduction in hypoglycemic events (- 1.29 vs. - 0.81 events during 6 months; p = 0.012). Mean insulin doses after titration were 0.43 ± 0.36 and 0.40 ± 0.28 U/kg in Gla-300 and Gla-100 switchers, respectively. Factors that significantly influenced BIA choice included a lower risk of hypoglycemia (for Gla-300) and physician familiarity (for Gla-100). Outcomes for insulin-naïve patients were broadly similar to those of switchers.

CONCLUSIONS

In this real-world European study, patients with T2D who switched therapy to Gla-300 or Gla-100 had improved glycemic control and reduced hypoglycemia at 6 months, with significant hypoglycemia advantages with Gla-300.

Real-world safety and effectiveness of insulin glargine 300 U/mL in participants with type 2 diabetes who fast during Ramadan: The observational ORION study

AIMS

ORION evaluated the safety and effectiveness of Gla-300 in insulin-treated people with T2DM before, during and after Ramadan, in a real-world setting.

METHODS

This prospective, observational study across 11 countries included participants with T2DM treated with Gla-300 in pre-Ramadan, Ramadan and post-Ramadan periods. The primary endpoint was the percentage of participants experiencing ≥1 event of severe and/or symptomatic documented hypoglycaemia with self-monitored plasma glucose (SMPG) ≤70 mg/dL during Ramadan. Secondary endpoints included change in HbA_1c and insulin dose and adverse events (AEs).

RESULTS

The mean ± SD number of fasting days was 30.1 ± 3.2. The percentage of participants experiencing ≥1 event of severe and/or symptomatic documented hypoglycaemia (SMPG ≤70 [<54] mg/dL) was low in the pre-Ramadan (2.2% [0.8%]), Ramadan (2.6% [0%]) and post-Ramadan (0.2% [0%]) periods. No participants reported severe hypoglycaemia during Ramadan or post-Ramadan; one participant reported severe hypoglycaemia in pre-Ramadan. HbA_1c fell pre- to post-Ramadan, and Gla-300 daily dose (mean ± SD) was reduced pre-Ramadan to Ramadan (from 25.6 ± 11.9 U/0.32 ± 0.14 U/kg to 24.4 ± 11.5 U/0.30 ± 0.13 U/kg). Incidence of AEs was 5.5%.

CONCLUSIONS

In ORION, people with T2DM treated with Gla-300 who fasted during Ramadan had a low risk of severe/symptomatic hypoglycaemia and improved glycaemic control.

Effectiveness and safety of insulin glargine 300 unit/mL in Japanese type 2 diabetes mellitus patients: a 12-month post-marketing surveillance study (X-STAR study)

BACKGROUND

With limited real-world insulin glargine 300 unit/mL (Gla-300) data available, we assessed the effectiveness and safety of Gla-300 in the Japanese type 2 diabetes mellitus (T2DM) population.

RESEARCH DESIGN AND METHODS

X-STAR was a prospective, observational, 12-month post-marketing study of Gla-300 from 2015 to 2018. T2DM patients received Gla-300 as the first insulin (insulin-naïve) or after treatment with another type of insulin (insulin-experienced).

RESULTS

We identified 1,227 insulin-naïve and 3,394 insulin-experienced patients. Insulin-naïve group increased the Gla-300 starting dose by 2.80 U/day during 12 months (7.49 to 10.29 U/day). Mean HbA1c reduced by 1.99% (9.82 to 7.83%), and 28.4% showed HbA1c < 7.0%. Insulin-experienced group had a baseline insulin dose of 14.86 U/day, which increased by 0.73 U/day. Mean HbA1c reduced by 0.18% (7.99 to 7.81%), and 24.6% showed HbA1c < 7.0%. Adverse drug reactions occurred in 3.42% (insulin-naïve) and 4.45% (insulin-experienced); symptomatic hypoglycemia (2.93% and 3.86%, respectively) was the most common in both groups.

CONCLUSIONS

Gla-300, in clinical practice, provides an effective and safe therapy as HbA1c was reduced/maintained in insulin-naïve/experienced Japanese T2DM patients without new safety signal. This study provides insights into the current Japanese clinical practices where insulin use is delayed and conservative despite relatively low HbA1c achievement.

Efficacy and Safety of Insulin Glargine 300 Units/mL (Gla-300) Versus Insulin Glargine 100 Units/mL (Gla-100) in Children and Adolescents (6-17 years) With Type 1 Diabetes: Results of the EDITION JUNIOR Randomized Controlled Trial

OBJECTIVE

To compare efficacy and safety of insulin glargine 300 units/mL (Gla-300) and 100 units/mL (Gla-100) in children and adolescents (6-17 years old) with type 1 diabetes.

RESEARCH DESIGN AND METHODS

EDITION JUNIOR was a noninferiority, international, open-label, two-arm, parallel-group, phase 3b trial. Participants were randomized 1:1 to Gla-300 or Gla-100, titrated to achieve fasting self-monitored plasma glucose levels of 90-130 mg/dL (5.0-7.2 mmol/L), with continuation of prior prandial insulin. The primary end point was change in HbA_1c from baseline to week 26. Other assessments included change in fasting plasma glucose (FPG), hypoglycemia, hyperglycemia with ketosis, and adverse events.

RESULTS

In 463 randomized participants (Gla-300, n = 233; Gla-100, n = 230), comparable least squares (LS) mean (SE) reductions in HbA_1c were observed from baseline to week 26 (-0.40% [0.06%] for both groups), with LS mean between-group difference of 0.004% (95% CI -0.17 to 0.18), confirming noninferiority at the prespecified 0.3% (3.3 mmol/mol) margin. Mean FPG change from baseline to week 26 was also similar between groups. During the 6-month treatment period, incidence and event rates of severe or documented (≤70 mg/dL [≤3.9 mmol/L]) hypoglycemia were similar between groups. Incidence of severe hypoglycemia was 6.0% with Gla-300 and 8.8% with Gla-100 (relative risk 0.68 [95% CI 0.35-1.30]). Incidence of any hyperglycemia with ketosis was 6.4% with Gla-300 and 11.8% with Gla-100.

CONCLUSIONS

Gla-300 provided similar glycemic control and safety profiles to Gla-100 in children and adolescents with type 1 diabetes, indicating that Gla-300 is a suitable therapeutic option in this population.

Long-term safety and effectiveness of biosimilar insulin glargine in Japanese patients with diabetes mellitus in routine clinical practice: results of a post-marketing safety study

Objective: To evaluate the long-term safety and effectiveness of biosimilar insulin glargine (GLY) in real-world clinical practice.Methods: This prospective, non-interventional, multicenter, observational, post-marketing safety study (PMSS) enrolled Japanese patients with type 1 or 2 diabetes mellitus (T1DM or T2DM) starting GLY therapy, and was required by Japanese Pharmaceutical Affairs Law mandating post-marketing safety surveillance to acquire safety and effectiveness data of biosimilar products. Data collected from the 12-month observation included patient characteristics, adverse events, and blood glucose control.Results: The study enrolled 141 patients with T1DM and 1104 patients with T2DM. Pre-study insulin was used by 94.1% of patients with T1DM and 75.0% with T2DM. 65.4% of patients with T1DM and 64.3% with T2DM switched from the reference product (GLY-switched), while 25.0% with T2DM were insulin-naive. Adverse events were reported by 5.7% and 8.5% in T1DM and T2DM, respectively. Similar incidences were reported in GLY-switched. Adverse events were reported by 10.7% in insulin-naive T2DM. Baseline mean hypoglycemic events/month were 1.8 and 0.1 in T1DM and T2DM, respectively: the mean change from baseline (CFB) was -1.2 (p = .066) and 0.0 (p = .915), respectively. Baseline mean HbA1c was 8.4% and 8.7% in T1DM and T2DM, respectively; the mean CFB was -0.5% (p < .001) and -0.9% (p < .001), respectively, and -1.5% (p < .001) in insulin-naive T2DM.Conclusions: This first long-term Japanese PMSS of GLY demonstrated adverse events, hypoglycemia, and glycemic control consistent with the known GLY profile for T1DM and T2DM patients, in routine clinical practice.

Rationale and methodology for a European pooled analysis of postmarketing interventional and observational studies of insulin glargine 300 U/mL in diabetes: protocol of REALI project

INTRODUCTION

Type 2 diabetes mellitus (T2DM) is a common and heterogeneous disease. Using advanced analytic approaches to explore real-world data may identify different disease characteristics, responses to treatment and progression patterns. Insulin glargine 300 units/mL (Gla-300) is a second-generation basal insulin analogue with preserved glucose-lowering efficacy but reduced risk of hypoglycaemia. The purpose of the REALI pooled analysis described in this paper is to advance the understanding of the effectiveness and real-world safety of Gla-300 based on a large European patient database of postmarketing interventional and observational studies.

METHODS AND ANALYSIS

In the current round of pooling, REALI will include data from up to 10 000 subjects with diabetes mellitus (mostly T2DM) from 20 European countries. Outcomes of interest include change from baseline to week 24 in haemoglobin A_1c, fasting plasma glucose, self-measured plasma glucose, body weight, insulin dose, incidence and rate of any-time-of-the-day and nocturnal hypoglycaemia. The data pool is being investigated using two complementary methodologies: a conventional descriptive, univariate and multivariable prognostic analysis; and a data-mining approach using subgroup discovery to identify phenotypic clusters of patients who are highly associated with the outcome of interest. By mid-2019, deidentified data of 7584 patients were included in the REALI database, with a further expected increase in patient number in 2020 as a result of pooling additional studies.

ETHICS AND DISSEMINATION

The proposed study does not involve collection of primary data. Moreover, all individual study protocols were approved by independent local ethics committees, and all study participants provided written informed consent. Furthermore, patient data is deidentified before inclusion in the REALI database. Hence, there is no requirement for ethical approval. Results will be disseminated via peer-reviewed publications and presentations at international congresses as data are analysed.

Glargine-300: An updated literature review on randomized controlled trials and real-world studies

Despite the availability of a variety of insulins, rates of insulinisation and the acceptance of insulin therapy is suboptimal in real-world clinical settings. Patient and physician concerns with hypoglycaemia and weight gain are the two key issues that serve to impede appropriate insulinisation in patients with diabetes. Recently introduced second-generation basal insulin analogues [for e.g., insulin glargine 300 U/mL (Gla-300) and insulin degludec] are designed to have improved pharmacokinetic profiles with an intention to deliver steady insulin levels over a longer period. Several randomised controlled and real-world studies have proven the resultant advantages of second-generations insulin analogues in lowering intra-individual variability in plasma insulin levels, flexibility in dosing, a sustained glucose-lowering effect, and decreasing the risk of hypoglycaemia. Gla-300 is one of the newer second-generation basal insulin analogues to have been approved for both type 1 and 2 diabetes. In this article, we review the currently available clinical and real-world data of Gla-300.

Efficacy and safety of insulin glargine 300 U/mL versus insulin glargine 100 U/mL in Asia Pacific insulin-naïve people with type 2 diabetes: The EDITION AP randomized controlled trial

AIM

To compare the efficacy and safety of Gla-300 versus Gla-100 in insulin-naïve people with type 2 diabetes in Asia Pacific.

MATERIALS AND METHODS

In this open-label, randomized, active-controlled, 26-week study, insulin-naïve participants with type 2 diabetes inadequately controlled with non-insulin antihyperglycaemic drugs were randomized (2:1) to Gla-300 or Gla-100. The initial daily dose of basal insulin was 0.2 U/kg and was adjusted at least weekly for 8-12 weeks to a target fasting self-monitored plasma glucose (SMPG) of 4.4-5.6 mmol/L.

RESULTS

Of the 604 participants randomized, 570 (Gla-300, n = 375; Gla-100, n = 195) completed the study. Non-inferiority of Gla-300 versus Gla-100 in HbA1c reduction from baseline to week 26 was confirmed. In the Gla-300 and Gla-100 groups, 51.1% and 52.2% of participants achieved the HbA1c target of <7.0% (rate ratio [95% CI]: 0.98 [0.84 to 1.14]) and 19.1% and 21.9% achieved the target without hypoglycaemia during the last 12 weeks of treatment (rate ratio [95% CI]: 0.87 [0.63 to 1.20]). Changes in fasting plasma glucose and 24-hour average eight-point SMPG were comparable between groups. Incidence of hypoglycaemia at any time of day was similar between treatment groups at week 26, but incidence of any nocturnal hypoglycaemia was numerically lower with Gla-300 than Gla-100 over the initial 12-week titration period and 26-week on-treatment period. Rates of adverse events were similar between groups and low for serious adverse events.

CONCLUSIONS

Glycaemic control of Gla-300 is non-inferior to Gla-100 with a similar or lower incidence and proportion of hypoglycaemia in people with type 2 diabetes in Asia Pacific, reinforcing the results in the global EDITION programme.

Practical application of short-term intensive insulin therapy based on the concept of "treat to target" to reduce hypoglycaemia in routine clinical site

The aim is to devise a new short-term intensive insulin therapy (N-SIIT) based on the concept of "treat to target" to avoid hypoglycaemia and was applied it to various diabetic state. We determined dosage of 1 basal and 3 bolus "treat" insulin based on "target" blood glucose level and changed each insulin dose by small units (2 units) every day for 2 weeks. We evaluated the effects of N-SIIT in 74 subjects with type 2 diabetes (male 45, female 29, 64.9 ± 16.6 years old, HbA1c 10.4 ± 2.6%). Glargine U300 ("treat") and morning blood glucose level ("target") was significantly correlated with increasing insulin dose and decreasing blood glucose level in day 1-7, indicating that insulin amount was determined by target blood glucose level and lowered next target blood glucose level. Remission rates were 67.3% (Hypoglycaemia rate 5.6 %) in N-SIIT and 47.3% (Hypoglycaemia rate 38.1%) in conventional SIIT. Required amount of insulin would be automatically determined, depending on each patient pathophysiology and life style. This method is pretty simple, flexible and cheap, and provides information about the dynamic pathophysiological alteration of insulin resistance and glucotoxicity from the profile of blood glucose levels and insulin shot.

Switching to insulin glargine 300 units/mL in real-world older patients with type 2 diabetes (DELIVER 3)

AIM

To compare the second-generation basal insulin glargine 300 units/mL (Gla-300) and first-generation basal insulins on glycaemic control and hypoglycaemia risk in older adults with type 2 diabetes (T2D).

MATERIALS AND METHODS

DELIVER 3 was a retrospective observational cohort study of electronic medical records. A total of 1176 older adults (aged ≥ 65 years) with T2D and ≥1 HbA1c value during 6 month baseline and 3 to 6 month follow-up who switched from basal insulin to Gla-300 were propensity score-matched to 1176 older adults who switched to a first-generation basal insulin [insulin detemir (IDet) or insulin glargine 100 units/mL (Gla-100)]. Outcomes were follow-up HbA1c, achievement of HbA1c <7% and <8%, hypoglycaemia incidence and event rates, and healthcare resource utilization.

RESULTS

Following basal insulin switching, HbA1c reductions were greater/similar with Gla-300 versus IDet/Gla-100 (variable follow-up: -0.45% ± 1.40% vs. -0.29% ± 1.57%; P = .021; fixed follow-up: -0.48% ± 1.49% vs. -0.38% ± 1.59%; P = .114), while HbA1c goal attainment was similar in both cohorts. Gla-300 was associated with less hypoglycaemia [event rate: adjusted rate ratio (aRR): 0.63, 95% CI: 0.53-0.75; P < .001] and inpatient/emergency department-associated hypoglycaemia (adjusted hazard ratio: 0.58, 95% CI: 0.37-0.90; P = .016; aRR: 0.43, 95% CI: 0.31-0.60; P < .001) by variable follow-up. By fixed follow-up, hypoglycaemia results significantly or numerically favoured Gla-300.

CONCLUSION

Among older adults with T2D, switching to Gla-300 versus Gla-100/IDet was associated with greater/similar improvements in glycaemic control, and generally less hypoglycaemia.

Comparison of the efficacy and safety of once-daily insulin degludec/insulin aspart (IDegAsp) and long-acting second-generation basal insulin (insulin degludec and insulin glargine 300 units/mL) in insulin-naïve Japanese adults with type 2 diabetes: a pilot, randomized, controlled study

To examine the efficacy and safety of once-daily insulin degludec/insulin aspart (IDegAsp) or once-daily second-generation basal insulin analogs (insulin degludec and insulin glargine 300 units/mL) in insulin-naïve Japanese adults with type 2 diabetes in routine clinical practice. A 12-week multicenter, open-label, randomized, pilot study was performed in 52 subjects with type 2 diabetes treated with oral antidiabetic drugs (OADs). Subjects were randomized to once-daily IDegAsp (n = 26) or basal insulin (n = 26). The primary endpoint was percent change in HbA1c from baseline to week 12. Furthermore, it was analyzed post hoc in subgroups stratified by baseline HbA1c. During a follow-up period, percent change in HbA1c was not significantly different between the two groups (p = 0.161). Daily insulin doses and frequency of overall hypoglycemia were also similar in the two groups. In post hoc analyses, once-daily basal insulin was more effective than IDegAsp in subjects with HbA1c more than or equal to 8.5% (p < 0.05); however, in subjects with HbA1c less than 8.5%, once-daily IDegAsp showed a significant improvement in percent change in HbA1c at week 12, compared with basal insulin (p < 0.01). Although there was no apparent difference in the HbA1c-lowering effects between two groups, when compared in subjects with HbA1c less than 8.5%, once-daily IDegAsp showed a significant effect in comparison with once-daily basal insulin. These findings suggest that the baseline HbA1c level might provide the important information for choosing IDegAsp or basal insulin in patients insufficiently controlled with OADs. This trial was registered with UMIN (no. UMIN000035431).

Effect of a single dose of insulin glargine/lixisenatide fixed ratio combination (iGlarLixi) on postprandial glucodynamic response in Japanese patients with type 2 diabetes mellitus: A phase I randomized trial

This report describes novel clinical data assessing the pharmacodynamics of insulin glargine/lixisenatide (iGlarLixi) compared with placebo and insulin glargine alone, to determine pharmacokinetics of lixisenatide, and to assess safety of iGlarLixi in Japanese people with type 2 diabetes mellitus (T2DM). In a single-centre, open-label, randomized, placebo-controlled cross-over study, participants received subcutaneous iGlarLixi 5 U/5 μg and 10 U/10 μg, placebo, and 5 U insulin glargine. The primary endpoint was area under the postprandial plasma glucose (PPG) curve (AUC_0-2h ). A total of 20 participants completed all study periods. iGlarLixi 5 U/5 μg and 10 U/10 μg reduced mean PPG dose-dependently compared with placebo and insulin glargine 5 U. Both combinations significantly reduced PPG-AUC_0-2h dose-dependently compared with placebo (least squares mean difference -7.48 mmol h/L for 5 U/5 μg, -10.75 mmol h/L for 10 U/10 μg; P < 0.0001). iGlarLixi 5 U/5 μg reduced PPG-AUC_0-2h significantly compared with insulin glargine 5 U (-0.76 mmol h/L; P < 0.0001). No symptomatic hypoglycaemia occurred during the study. iGlarLixi single subcutaneous injections significantly and dose-dependently reduced PPG compared to placebo or insulin glargine in Japanese participants with T2DM. iGlarLixi was safe and well tolerated, and would be expected to provide the 24-hour plasma glucose-lowering effects of insulin glargine and the postprandial antihyperglycaemic effects of lixisenatide.

Achieving Glycaemic Control with Concentrated Insulin in Patients with Type 2 Diabetes

The recent introduction of the second-generation long-acting analogue insulins degludec and insulin glargine U300 have increased the choice of basal insulin therapy for patients with type 2 diabetes. The pharmacokinetic and pharmacodynamic properties of these insulins result in a flatter profile that lasts over 24 h and provides an increased window of administration of 6 h once daily. Large-scale multicentre randomised clinical trial programmes (BEGIN for degludec U100 and U200 and EDITION for glargine U300) evaluating these insulin therapies against glargine U100 have demonstrated that they are either non-inferior or superior for glycaemic efficacy and safety, but less likely to result in severe or nocturnal hypoglycaemia than glargine U100. The disposable pen devices for these insulins have been designed with patient satisfaction and convenience in mind. No concerns have arisen with adverse events with insulin analogues or cardiovascular safety from the ORIGIN and DEVOTE trials. As they demonstrate equivalent glycaemic efficacy to other basal insulins, they should be considered more in selected patient groups including those with recurrent or increased risk of hypoglycaemia, especially severe or nocturnal episodes, in the elderly or those living alone, and in patients with multiple co-morbidities such as cardiovascular or renal disease.

Hypoglycaemia and treatment patterns among insulin-treated patients with type 2 diabetes who switched to insulin glargine 300 units/mL versus other basal insulin in a real-world setting

INTRODUCTION

Type 2 diabetes (T2D) is characterized by worsening pancreatic β-cell function often requiring treatment escalation with oral antidiabetic drugs (OADs), glucagon-like peptide-1 and eventually insulin. Although there is much evidence available on the initiation of basal insulins, fewer studies have investigated the effects of switching from one basal insulin to another. This study aims to evaluate treatment persistence and hypoglycaemia in adult patients with T2D on prior basal insulin who were switched to insulin glargine 300 units/mL (Gla-300) or other basal insulins in a real-world setting.

MATERIALS AND METHODS

This study is a retrospective cohort analysis of patient-level data extracted from the Optum® Clinformatics™ database between 1 October 2014 and 30 June 2016. Adult patients (≥18 years) with T2D who were being treated with basal insulin during the 6-month baseline period, who switched to either Gla-300 or other basal insulins, were followed up for ≥3 months after switching. Outcomes included treatment persistence, and incidence and number of hypoglycaemic events.

RESULTS

Of the included patients, 1204 switched to Gla-300 and 616 switched to other basal insulins. Adjusting for baseline confounders, patients who switched to Gla-300 were 34% less likely to discontinue their basal insulin than patients who switched to other basal insulins (hazard ratio [HR] 0.66; 95% confidence interval [CI] 0.54-0.81; P < 0.001). Patients who switched to Gla-300 were less likely to experience hypoglycaemia at 3-month follow-up (odds ratio [OR] 0.56, 95% CI 0.32-0.97; P = 0.039) and at 6-month follow-up (OR 0.58, 95% CI 0.38-0.87; P = 0.009) compared with patients who switched to other basal insulins.

CONCLUSIONS

Patients with T2D on prior basal insulin in a real-world setting who switched to Gla-300 were more persistent with their basal insulin and experienced less hypoglycaemia than patients who switched to other basal insulins.

Reporting of hypoglycaemia in clinical trials of basal insulins: A need for consensus

Hypoglycaemia is a common side-effect of diabetes therapies, particularly insulin, and imposes a substantial burden on individuals and healthcare systems. Consequently, regulatory approval of newer basal insulin (BI) therapies has relied on demonstration of a balance between achievement of good glycaemic control and less hypoglycaemia. Randomized controlled trials (RCTs) are the gold standard for assessing efficacy and safety, including hypoglycaemia risk, of BIs and are invaluable for obtaining regulatory approval. However, their highly selected patient populations and their conditions lead to results that may not be representative of real-life situations. Real-world evidence (RWE) studies are more representative of clinical practice, but they also have limitations. As such, data both from RCTs and RWE studies provide a fuller picture of the hypoglycaemia risk with BI therapies. However, substantial differences exist in the way hypoglycaemia is reported across these studies, which confounds comparisons of hypoglycaemia frequency among different BIs. This problem is ongoing and persists in recent trials of second-generation BI analogues. Although they provide a lower risk of hypoglycaemia when compared with earlier BIs, they do not eliminate it. This review describes differences in the way hypoglycaemia is reported across RCTs and RWE studies of second-generation BI analogues and examines potential reasons for these differences. For studies of BIs, there is a need to standardize aspects of design, analysis and methods of reporting to better enable interpretation of the efficacy and safety of such insulins among studies; such aspects include length of follow-up, glycaemic targets, hypoglycaemia definitions and time intervals for determining nocturnal events.

Use of Insulin Glargine 100 U/mL for the Treatment of Type 2 Diabetes Mellitus in East Asians: A Review

Insulin glargine (IGlar) 100 U/mL (IGlar-100) is widely used in East Asian countries for the treatment of type 2 diabetes mellitus (T2DM) and is the gold standard of basal insulin treatment. In this review we summarize key information about clinical experience with IGlar-100 in East Asian patients with T2DM, including findings from clinical trials and postmarketing studies. We also provide recommendations and opinions on the optimal use of IGlar-100 in this population. The findings from the studies highlighted in our review indicate that IGlar-100 can be a suitable treatment option for East Asians with T2DM, from initial therapy in combination with oral antihyperglycemic medications through to different combinations and intensification models.

Efficacy and safety of the second generation basal insulin analogs in type 2 diabetes mellitus: A critical appraisal

Type 2 diabetes mellitus is a progressive disease, which requires insulin treatment when other management is no longer effective. Although, insulin plays a vital role in the treatment of diabetes, conventional basal insulins have certain limitations, which have led to the development of more stable and peak less analogues.

OBJECTIVES

To analyze the efficacy and safety of second generation vs. first generation basal insulins, and the efficacy and safety of second generation vs. second generation basal insulins, in patients with type 2 diabetes mellitus, from the evidence provided by head-to-head randomized controlled trials.

METHODS

The following electronic databases were searched: PubMed and MEDLINE, Scopus, BIOSIS, Embase, ClinicalTrials.gov, Google Scholar, and Springer Online Archives Collection, from January 1966 to October 2018. Articles resulting from these searches and relevant references cited in those articles were examined.

RESULTS

The efficacy among insulins evaluated was similar, however, second generation insulins cause a lower risk of hypoglycemia compared to first generation insulins. A single study showed similar metabolic control with subtle differences in the risk of hypoglycemia among second generation insulins.

CONCLUSIONS

The second-generation basal insulins result in metabolic control similar to first generation insulins, with lower risk of hypoglycemia. Second-generation insulins have comparable efficacy, with some differences in the risk of hypoglycemia.
