Abstract
Accumulating evidence indicates the occurrence and development of diabetic complications relates to not only constant high plasma glucose, but also glucose fluctuations which affect various kinds of molecular mechanisms in various target cells and tissues. In this review, we detail reactive oxygen species and their potentially damaging effects upon glucose fluctuations and resultant downstream regulation of protein signaling pathways, including protein kinase C, protein kinase B, nuclear factor-κB, and the mitogen-activated protein kinase signaling pathway. A deeper understanding of glucose-fluctuation-related molecular mechanisms in the development of diabetic complications may enable more potential target therapies in future.

Abstract
UNLABELLED Video abstract: View a video abstract for this article. AIMS This multicentre (N = 104), randomized controlled phase 4 study compared the efficacy and safety of insulin glargine 300 units/mL (Gla-300) with insulin glargine 100 units/mL (Gla-100) in patients with type 1 diabetes (T1D). MATERIALS AND METHODS Patients were randomized 1:1 to self-perform morning Gla-300 or Gla-100 injections daily for 16 weeks. The primary endpoint was percentage of time blood glucose remained in the target range (70-180 mg/dL) during Week 15/16, measured by blinded continuous glucose monitoring. Secondary endpoints included incidence and rate of nocturnal symptomatic hypoglycaemia (≤70 mg/dL), glycaemic variability parameters and safety assessments. Exploratory analyses were performed in patients with glycated haemoglobin (HbA1c) <7.5% at Week 16. RESULTS Overall, 638 patients with T1D were included (Gla-300, n = 320; Gla-100, n = 318). In the modified intent-to-treat (mITT) population, no differences between Gla-300 and Gla-100 were observed in time in range, in glycaemic variability, or in incidence or rates of nocturnal symptomatic hypoglycaemia. In exploratory analyses of patients with HbA1c <7.5% at Week 16, Gla-300 recipients had greater improvement in time in range over 24 hours, during the day and at night compared with Gla-100 recipients (P < 0.05), with small increases in overall hypoglycaemia. CONCLUSIONS Time in range and glycaemic variability were similar for Gla-300 and Gla-100 recipients at the end of study in the mITT population of relatively well-controlled patients with T1D. In patients with end-of-study HbA1c <7.5%, exploratory analyses suggested that Gla-300 provided improvements in time in range compared with Gla-100.

Abstract
BACKGROUND One major advantage of automated over manual clamps are continuous measurements of blood glucose concentrations (BG) allowing frequent adaptations in glucose infusion rates (GIR). However, BG measurements might be affected by changes in blood dilution. ClampArt®, a modern automated clamp device, corrects BG measurements for blood dilution, but the impact of this correction is unclear. METHODS The authors performed a retrospective analysis of BG during glucose clamps comparing values with a fixed dilution factor with those corrected for the actual blood dilution. RESULTS Clamp quality substantially improved with the consideration of blood dilution: Mean accuracy fell from 8.1% ± 2.9% to 4.1% ± 0.8%, precision improved from 9.6 ± 3.6 mg/dl to 3.7 ± 1.3 mg/dl and control deviation from -2.6 ± 4.2 mg/dl to 0.2 ± 0.2 mg/dl. CONCLUSIONS Correcting continuous BG measurements for blood dilution significantly increases BG measurement and clamp quality.

Abstract
OBJECTIVE Subcutaneous (sc) administration of long-acting insulin analogs is often employed in multiple daily injection (MDI) therapy of type 1 diabetes (T1D) to cover patient's basal insulin needs. Among these, insulin glargine 100 U/mL (Gla-100) and 300 U/mL (Gla-300) are formulations indicated for once daily sc administration in MDI therapy of T1D. A few semi-mechanistic models of sc absorption of insulin glargine have been proposed in the literature, but were not quantitatively assessed on a large dataset. The aim of this paper is to propose a model of sc absorption of insulin glargine able to describe the data and provide precise model parameters estimates with a clear physiological interpretation. METHODS Three candidate models were identified on a total of 47 and 77 insulin profiles of T1D subjects receiving a single or repeated sc administration of Gla-100 or Gla-300, respectively. Model comparison and selection were performed on the basis of their ability to describe the data and numerical identifiability. RESULTS The most parsimonious model is linear two-compartment and accounts for the insulin distribution between the two compartments after sc administration through parameter k. Between the two formulations, we report a lower fraction of insulin in the first versus second compartment (k = 86% versus 94% in Gla-100 versus Gla-300, p < 0.05), a lower dissolution rate from the first to the second compartment ([Formula: see text] versus 0.0008 min-1 in Gla-100 versus Gla-300, p << 0.001), and a similar rate of insulin absorption from the second compartment to plasma ([Formula: see text] versus 0.0016 min-1 in Gla-100 versus Gla-300, p = NS), in accordance with the mechanisms of insulin glargine protraction. CONCLUSIONS The proposed model is able to both accurately describe plasma insulin data after sc administration and precisely estimate physiologically plausible parameters. SIGNIFICANCE The model can be incorporated in simulation platforms potentially usable for optimizing basal insulin treatment strategies.

Abstract
Since the introduction of insulin as a life-saving agent for patients with type 1 diabetes, insulin preparations have evolved to approximate physiologic insulin delivery profiles to meet prandial and basal insulin needs. While prandial insulins are designed to have quick time–action profiles that minimize postprandial glucose excursions, basal insulins are designed to have a protracted time–action profile to facilitate basal glucose control over 24 h. Given that all insulins have the same mechanism of action at the target tissue level, the differences in time–action profiles are achieved through different mechanisms of protraction, resulting in different behaviors in the subcutaneous space and different rates of absorption into the circulation. Herein, we evaluate the differences in basal insulin preparations based on their differential mechanisms of protraction, and the resulting clinical action profiles. Multiple randomized control trials and real-world evidence studies have demonstrated that the newer second-generation basal insulin analogs, insulin glargine 300 units/mL and insulin degludec 100 or 200 units/mL, provide stable glycemic control with once-daily dosing and are associated with a reduced risk of hypoglycemia compared with previous-generation basal insulin analogs insulin glargine 100 units/mL and insulin detemir. These advantages can lead to decreased healthcare resource utilization and cost. With this collective knowledge, healthcare providers and payers can make educated and well-informed decisions when determining which treatment regimen best meets the needs of each individual patient.

Abstract
A substantial proportion of patients with suboptimal control of their type 2 diabetes experience delays in treatment intensification. Additionally, patients often experience overuse of basal insulin, commonly referred to as "over-basalization," whereby basal insulin continues to be uptitrated in order to meet targets, when addition of a mealtime bolus insulin dose may be a more appropriate option. In order to overcome these challenges, there is a need to develop the capacity of allied healthcare professionals to provide appropriate support to these patients, such as during initiation or titration of basal insulin. Pharmacists play an integral role in healthcare delivery, with patients seeing their pharmacist, on average, seven times more often than their primary care physician. This places pharmacists in a unique position to provide diabetes education and care, which may help patients avoid clinical inertia. Nevertheless, the management of the disease with basal insulin is becoming increasingly complex, with growing numbers of treatment options (such as recent second-generation longer-acting basal insulin formulations) and frequently updated titration algorithms. The two most common titration schedules specify either increasing doses by a set amount every 2-3 days or a treat-to-target strategy. Neither schedule has been shown to be superior, and the decision to use one or the other should be based on a discussion between the clinician and patient after assessment of mental and physical acumen, comfort of both parties, and follow-up plans. This review article discusses basal insulin therapy options and titration algorithms from the unique perspective of the pharmacist in order to help ensure that optimal antidiabetes therapy is initiated, appropriately titrated, and maintained.Funding: Sanofi US, Inc.

Abstract
BACKGROUND A head-to-head trial (NCT03078478) between insulin degludec and insulin glargine U300 with the primary objective of comparing the risk of hypoglycemia is being conducted. During trial conduct, safety concerns related to the glycemic data collection system led to a postinitiation protocol amendment, described here. METHODS This randomized (1:1), open-label, treat-to-target, multinational trial was initiated in March 2017 with a planned treatment period of 52 weeks (16 weeks titration + 36 weeks maintenance). Overall, ~1600 insulin-experienced patients at risk of developing hypoglycemia based on predefined risk factors were included. The protocol amendment implemented in February 2018 resulted in assuring patient safety and an extension of the total treatment period up to 88 weeks (16 weeks titration + variable maintenance 1 + 36 weeks maintenance 2). The original glycemic data collection system (MyGlucoHealth blood glucose meter + electronic diary) was discontinued because of safety concerns and replaced with an Abbott blood glucose meter and paper diary to collect self-measured blood glucose and hypoglycemic episodes. The primary endpoint of number of severe or blood-glucose confirmed symptomatic hypoglycemic episodes will be evaluated with the same analysis duration and statistical methods as the original protocol. Only relevant changes were implemented to maintain patient safety while permitting evaluation of the scientific objectives of the trial. CONCLUSIONS These observations highlight the importance of safety surveillance during trial conduct despite the use of currently marketed glucose monitoring devices. The prompt protocol amendment and ensuing actions ensured that the scientific integrity of the trial was not compromised.

Abstract
Insulin initiation and titration can be challenging for many primary care providers who are involved in the treatment of patients with type 2 diabetes. Despite the introduction of advanced insulin analogs and improvements in insulin delivery devices, many patients with type 2 diabetes continue to experience suboptimal glycemic control. With an increasing number of treatment options available, type 2 diabetes management is moving away from a "one-size-fits-all" approach and toward individualized treatment regimens based on particular patient needs. Given this, nurse practitioners, physician assistants, pharmacists, and certified diabetes educators are becoming increasingly valuable resources in busy primary care practices.

Abstract
AIMS/INTRODUCTION We compared the efficacy and safety of insulin glargine 300 U/mL (Gla300) and insulin degludec U100 (Deg) using a flash glucose monitoring system. MATERIALS AND METHODS A total of 24 Japanese patients with type 2 diabetes were randomized to receive once-daily Gla300 (n = 12) or Deg (n = 12) in the morning. The primary end-points were the mean percentage of time in the target glucose range (70-179 mg/dL) and hypoglycemia (<70 mg/dL), as measured using flash glucose monitoring during the last 7 days of each 14-day period. RESULTS The percentages of time with glucose levels <70 mg/dL were not significantly different between the two insulin treatments. No significant differences were observed in the percentages of time with glucose levels of 70-179 mg/dL or ≥180 mg/dL. The percentage of time with nocturnal hypoglycemia with Gla300 was significantly lower than that with Deg treatment (P = 0.021). This difference might be attributable to the difference in the duration of action between the two formulations, and the incidence of nocturnal hypoglycemia with Deg treatment was associated with the concomitant use of metformin (P = 0.035). CONCLUSIONS The two formulations were comparable in efficacy, whereas the incidence of nocturnal hypoglycemia was significantly lower with Gla300. Thus, the present study suggests that, although Gla300 and Deg are comparable long-acting insulin analogs, Gla300 is safer with respect to the incidence of hypoglycemia.

Abstract
AIMS/INTRODUCTION Compared with glargine 100 U/mL (Gla100), glargine 300 U/mL (Gla300) and degludec (Deg) - the ultralong-acting insulins - reportedly have more stable effects and reduce the risk of hypoglycemia. Currently, they are considered to be the most useful basal insulins. The present study aimed to compare the efficacy and safety of Gla300 and Deg on glycemic control using continuous glucose monitoring. MATERIALS AND METHODS In this single-center, open-label, parallel-group, two-period, cross-over study, 30 patients with type 2 diabetes were randomized to once-daily Gla300 followed by Deg with the same units (n = 15) or vice versa (n = 15). The primary end-points of this study were the mean percentage of time within the target glucose range of 70-180 mg/dL as efficacy and hypoglycemia of <70 mg/dL as safety indicators, as measured using continuous glucose monitoring during each treatment period. RESULTS The mean percentage of time within the target glucose range was not different between Gla300 and Deg (77.8 ± 19.2 vs 76.9 ± 18.3%, P = 0.848). However, the mean percentage of time of hypoglycemia with Gla300 was significantly lower than that of Deg (1.3 ± 2.7 vs 5.5 ± 6.4%, P = 0.002). In the secondary safety end-points, the mean percentage of time of severe hypoglycemia (<54 mg/dL) or nocturnal hypoglycemia with Gla300 was also significantly lower than that of Deg. CONCLUSIONS The present study showed the comparable efficacy of Gla300 and Deg on glycemic control; however, the risk of hypoglycemia was markedly lower for Gla300 than for Deg.

Abstract
The treatment of type 2 diabetes (T2D) is often complicated by factors such as patient co-morbidities, complex drug-drug interactions, and management of adverse events. In addition, some of these factors are highly dependent on the nature of the treatment regimen and the molecular and physical properties of the drugs being used to treat patients with this disease. This calls for a better understanding of how the properties of individual drugs affect the overall outcome for patients with diabetes. Clinical pharmacology studies to assess the pharmacokinetic (PK) and pharmacodynamic (PD) characteristics of new diabetes drugs play an important role in advancing our understanding of the interactions between a drug and the human body. Specific PK and PD techniques such as the glucose clamp test can be applied to assess the properties of drugs used for the treatment of diabetes. Basal insulin analogs are a common treatment option for the maintenance of glycemic control in patients with T2D. These drugs work by mimicking endogenous insulin secretion within the body and provide stable and prolonged insulin action to achieve optimal glucose levels. Insulin glargine 300 U/mL (Gla-300) and insulin degludec (IDeg) 100 U/mL and 200 U/mL represent a new generation of longer-acting basal insulins. These drugs demonstrate improved PK and PD properties compared with previous basal insulins, allowing them to more closely mimic physiological basal insulin secretion. Here we review the methods used to evaluate the PK and PD profiles of Gla-300 and IDeg and describe studies that have investigated the PK/PD properties of these drugs in type 1 diabetes. The aim of this review is to inform primary care physicians of the value and limitations of data from clinical pharmacology studies when prescribing these agents for the management of T2D.

Abstract
Type 2 diabetes (T2D) is a progressive disease caused by insulin resistance and associated progressive β-cell functional decline, as well as multiple other related metabolic and pathophysiologic changes. Left unchecked, T2D increases the risk of long-term microvascular and cardiovascular complications and is associated with excess morbidity and mortality. Despite multiple effective options for reducing hyperglycemia, patients are not optimally managed, largely due to delays in appropriate and timely advancement of therapy. Glucagon-like peptide-1 receptor agonists and basal insulin are recommended by treatment guidelines as effective options for advancing therapy to achieve glycemic control. However, injected therapies often face resistance from patients and clinicians. Glucagon-like peptide-1 receptor agonists are associated with weight loss, low risk of hypoglycemia, and potential beneficial cardiovascular effects. The class is recommended for patients across the spectrum of disease severity and represents an attractive option to add to basal insulin therapy when additional control is needed. Newer second-generation basal insulin analogues offer advantages over first-generation basal insulins in terms of lower hypoglycemia rates and greater flexibility in dosing. Incorporating injectable therapy into patient care in a timely manner has the potential to improve outcomes and must not be overlooked. Primary care clinicians play a significant role in managing patients with T2D, and they must be able to address and overcome patient resistance and their own barriers to advancing therapy if optimal treatment outcomes are to be achieved. The purpose of this expert opinion article was to provide a commentary on the key principle of advancing therapy with injectables to control hyperglycemia.

Abstract
OBJECTIVE This study characterized the pharmacokinetics (PK), pharmacodynamics (PD), and endogenous (hepatic) glucose production (EGP) of clinical doses of glargine U300 (Gla-300) and glargine U100 (Gla-100) under steady-state (SS) conditions in type 1 diabetes mellitus (T1DM). RESEARCH DESIGN AND METHODS T1DM subjects (N = 18, age 40 ± 12 years, T1DM duration 26 ± 12 years, BMI 23.4 ± 2 kg/m2, A1C 7.19 ± 0.52% [55 ± 5.7 mmol · mol-1-1]) were studied after 3 months of Gla-300 or Gla-100 (evening dosing) titrated to fasting euglycemia (random, crossover) with the euglycemic clamp using individualized doses (Gla-300 0.35 ± 0.08, Gla-100 0.28 ± 0.07 units · kg-1). RESULTS Plasma free insulin concentrations (free immunoreactive insulin area under the curve) were equivalent over 24 h with Gla-300 versus Gla-100 (point estimate 1.11 [90% CI 1.03; 1.20]) but were reduced in the first 6 h (0.91 [90% CI 0.86; 0.97]) and higher in the last 12 h postdosing (1.38 [90% CI 1.21; 1.56]). Gla-300 and Gla-100 both maintained 24 h euglycemia (0.99 [90% CI 0.98; 1.0]). The glucose infusion rate was equivalent over 24 h (1.03 [90% CI 0.88; 1.21]) but was lower in first (0.77 [90% CI 0.62; 0.95]) and higher (1.53 [90% CI 1.23; 1.92]) in the second 12 h with Gla-300 versus Gla-100. EGP was less suppressed during 0-6 h but more during 18-24 h with Gla-300. PK and PD within-day variability (fluctuation) was 50% and 17% lower with Gla-300. CONCLUSIONS Individualized, clinical doses of Gla-300 and Gla-100 resulted in a similar euglycemic potential under SS conditions. However, Gla-300 exhibited a more stable profile, with lower variability and more physiological modulation of EGP compared with Gla-100.

Abstract
INTRODUCTION Insulin glargine 300 U/mL (Gla-300, Toujeo®) is a long-acting, once-daily basal insulin with improved-more stable and smoother-pharmacokinetic and pharmacodynamic profiles compared to insulin glargine 100 U/mL (Gla-100) and insulin degludec (IDeg). These properties have been shown to translate into an effective HbA1c reduction with the advantage of a lower risk of hypoglycemia in randomized controlled trials of Gla-300 versus Gla-100. In this study, we assessed the effectiveness and safety of Gla-300 under real-world conditions in Switzerland. METHODS The prospective, observational, open-label, multicenter study TOP-2 explored the effectiveness of Gla-300 in adult patients with type 2 diabetes (T2D) uncontrolled (HbA1c 7.5-10%) on their previous basal insulin in Germany, Austria, and Switzerland. The primary endpoints were the percentages of patients achieving a fasting plasma glucose (FPG) of ≤ 6.1 mmol/L after 6 and 12 months. Secondary endpoints included changes in HbA1c, FPG, body weight, and insulin dose as well as hypoglycemia incidence and safety. Here we report the results for the Swiss patient cohort after 12 months of treatment with insulin glargine 300 U/mL. RESULTS The 62 patients (33 men) had a mean age of 65 years, a mean diabetes duration of 14 years, a mean body mass index (BMI) of 31 kg/m2, and were mainly switched from Gla-100 (44%) to Gla-300. The most common concomitant oral anti-diabetes therapy was metformin (65%). The mean individual HbA1c target chosen by the investigators was 7.4%. After 12 months of therapy, Gla-300 significantly reduced mean HbA1c from 8.2% to 7.6% (p < 0.0001). Likewise, Gla-300 significantly reduced mean FPG from 9.1 mmol/L to 7.4 mmol/L (p < 0.0001). At study end, 32% of patients achieved FPG ≤ 6.1 mmol/L, 55% achieved FPG ≤ 7.2 mmol/L , and 57% achieved their individual HbA1c target. Gla-300 was uptitrated to a mean dose of 40 units per day. Symptomatic hypoglycemia incidence after 12 months was low at 9.7% and a rate of 0.23 events per patient year. Body weight remained stable and was not significantly altered during the study. CONCLUSION Upon switching basaI insulin to Gla-300, overall glucose control significantly improved and glycemic targets were achieved with a low rate of hypoglycemia in T2D patients under real-world conditions in Switzerland.

Abstract
INTRODUCTION Administered basal insulin markedly influences the fasting plasma glucose (FPG) level of individuals with type 1 diabetes. Insulin degludec (IDeg) and insulin glargine U300 (IGlar U300) are now available as ultra-long-acting insulin formulations, but whether or how their glucose-stabilizing effects differ remains unclear. We will compare the effects of these basal insulins on parameters related to blood glucose control, with a focus on day-to-day glycemic variability, in individuals with type 1 diabetes treated with multiple daily injections. METHODS A multicenter, randomized, open-label, crossover, comparative study (Kobe Best Basal Insulin Study 2) will be performed at 13 participating institutions in Japan. A total of 46 C-peptide-negative adult outpatients with type 1 diabetes will be randomly assigned 1:1 by a centralized allocation process to IGlar U300 (first period)/IDeg (second period) or IDeg (first period)/IGlar U300 (second period) groups, in which subjects will be treated with the corresponding basal insulin for consecutive 4-week periods. The basal insulin will be titrated to achieve an FPG of less than 130 mg/dL initially and then less than 110 mg/dL if feasible. In the last week of each period, plasma glucose will be determined seven times a day by self-monitoring of blood glucose (SMBG) and intraday and day-to-day glucose excursions will be determined by flash glucose monitoring (FGM). The primary end point is comparison of day-to-day glycemic variability as evaluated by the standard deviation (SD) of FPG during the last week of each treatment period. Secondary end points include the coefficient of variance of FPG, the frequency of severe hypoglycemia as evaluated by SMBG, the duration of hypoglycemia as evaluated by FGM, intraday glycemic variability calculated from both SMBG and FGM data, and the administered insulin dose. PLANNED OUTCOMES The results of the study will be submitted for publication in a peer-reviewed journal to report differences in the effects of two ultra-long-acting basal insulins, IDeg and IGlar U300. CONCLUSION This head-to-head comparison will be the first study to compare the effects of IDeg and IGlar U300 on day-to-day FPG variability in C-peptide-negative individuals with type 1 diabetes.

Abstract
OBJECTIVE To compare insulin glargine 300 units/mL (Gla-300) versus insulin degludec 100 units/mL (IDeg-100) in this first head-to-head randomized controlled trial. RESEARCH DESIGN AND METHODS BRIGHT (NCT02738151) was a multicenter, open-label, active-controlled, two-arm, parallel-group, 24-week, noninferiority study in insulin-naive patients with uncontrolled type 2 diabetes. Participants were randomized 1:1 to evening dosing with Gla-300 (N = 466) or IDeg-100 (N = 463), titrated to fasting self-monitored plasma glucose of 80-100 mg/dL. The primary end point was HbA1c change from baseline to week 24. Safety end points included incidence and event rates of hypoglycemia. RESULTS At week 24, HbA1c improved similarly from baseline values of 8.7% (72 mmol/mol) in the Gla-300 group and 8.6% (70 mmol/mol) in the IDeg-100 group to 7.0% (53 mmol/mol)-least squares mean difference -0.05% (95% CI -0.15 to 0.05) (-0.6 mmol/mol [-1.7 to 0.6])-demonstrating noninferiority of Gla-300 versus IDeg-100 (P < 0.0001). Hypoglycemia incidence and event rates over 24 weeks were comparable with both insulins, whereas during the active titration period (0-12 weeks) the incidence and rate of anytime (24-h) confirmed hypoglycemia (≤70 and <54 mg/dL) were lower with Gla-300. Both insulins were properly titrated and exhibited no specific safety concerns. CONCLUSIONS Gla-300 and IDeg-100 provided similar glycemic control improvements with relatively low hypoglycemia risk. Hypoglycemia incidence and rates were comparable with both insulins during the full study period but lower in favor of Gla-300 during the titration period. The choice between these longer-acting basal insulins may be determined by factors such as access and cost, alongside clinical considerations.

Abstract
AIMS To compare clinical outcomes in patients with type 2 diabetes (T2D) switching from insulin glargine 100 units/mL (Gla-100) or insulin detemir (IDet) to insulin glargine 300 units/mL (Gla-300) or insulin degludec (IDeg). MATERIALS AND METHODS We conducted a retrospective, observational study of electronic medical records for Gla-300/IDeg adult switchers (March 1, 2015 to January 31, 2017) with active records for 12-month baseline (glycated haemoglobin [HbA1c] used a 6-month baseline period) and 6-month follow-up periods. Gla-300 and IDeg switchers were propensity score-matched using baseline demographic and clinical characteristics. Outcomes were HbA1c change and goal attainment (among patients with HbA1c captured at follow-up), and hypoglycaemia with fixed follow-up (intention-to-treat [ITT]; 6 months) and variable follow-up (on-treatment [OT]; to discontinuation or 6 months). RESULTS Each matched cohort comprised 1592 patients. The mean decrease in HbA1c and HbA1c goal (<7.0% [53 mmol/mol] and <8.0% [64 mmol/mol]) attainment rates were similar for Gla-300 (n = 742) and IDeg (n = 727) switchers. Using fixed follow-up (ITT method), hypoglycaemia incidence decreased significantly from baseline with Gla-300 (all hypoglycaemia: 15.6% to 12.7%; P = .006; hypoglycaemia associated with inpatient/emergency department [ED] encounter: 5.3% to 3.5%; P = .007), but not with IDeg. After adjusting for baseline hypoglycaemia, no significant differences in hypoglycaemia incidence and event rate were found at follow-up (ITT) for Gla-300 vs IDeg. Using variable follow-up (OT), hypoglycaemia incidence was similar in both groups, but Gla-300 switchers had a lower inpatient/ED hypoglycaemia event rate at follow-up (adjusted rate ratio 0.56; P = .016). CONCLUSIONS In a real-world setting, switching from Gla-100 or IDet to Gla-300 or IDeg was associated with similar improvements in glycaemic control and hypoglycaemia in adult patients with T2D.

Abstract
Insulin analogues play a key role in the effective management of type 2 diabetes. However, there are several behavioural barriers to appropriate early initiation of insulin therapy, despite compelling evidence supporting the benefits of this strategy in those patients for whom oral anti-diabetes agents provide insufficient control. The development of second-generation insulin analogues (insulin glargine 300 U/mL and insulin degludec) has provided physicians with agents that can provide comparable glycaemic control to first-generation insulin, but with a reduced risk of hypoglycaemia and modes of action suited to once-daily regimens. These characteristics may help overcome patient and physician concerns about early insulin use in disease management. To date, there have been no head-to-head comparisons of second-generation insulins: here we consider recent real-world evidence and the forthcoming direct comparison in the BRIGHT randomised controlled study, as presented at the recent 11th International Conference on Advanced Technologies & Treatments for Diabetes (ATTD) 2018.

Abstract
AIMS To explore comparative glycaemic control and hypoglycaemia incidence with insulin degludec 100U/mL (IDeg) or insulin glargine 300U/mL (Gla-300) versus glargine 100U/mL (Gla-100) in trial-level meta-analyses of phase 3a clinical trials including people with type-2 diabetes. METHODS Meta-analyses of HbA1c, fasting plasma glucose (FPG), average 24h self-measured plasma glucose (SMPG), pre-breakfast SMPG and hypoglycaemia incidence and rate, using data from the BEGIN (IDeg) and EDITION (Gla-300) insulin development programmes, were performed. RESULTS In BEGIN, despite greater FPG reduction with IDeg than Gla-100, HbA1c reduction was greater with Gla-100 (mean difference [95% CI] in HbA1c change: 0.09 [0.01-0.18] %) whereas in EDITION, there was no difference in FPG and HbA1c reduction between Gla-300 and Gla-100. Risk of nocturnal confirmed (<3.1mmol/L [<56mg/dL]) or severe hypoglycaemia, but not anytime (24h) events, was lower with IDeg than Gla-100 (relative risk [RR] 0.79 [0.66-0.94]) whereas Gla-300 was associated with reduced risk of nocturnal (RR 0.75 [0.61-0.92]) and anytime (24h) (RR 0.81 [0.69-0.94]) confirmed (<3.0mmol/L [<54mg/dL]) or severe hypoglycaemia versus Gla-100. CONCLUSIONS These trial-level meta-analyses suggest that despite greater reductions in FPG, IDeg was associated with less improvement in HbA1c versus Gla-100, with a hypoglycaemia benefit only evident at night. In contrast, Gla-300 showed similar HbA1c reduction to Gla-100, accompanied by lower risk of hypoglycaemia both at night and at any time of day. Gla-300 and IDeg appear more similar than dissimilar, but head-to-head trials are required.
