Abstract
Aim Insulin titration often faces inertia, hindering glycemic control. A patient-centered approach empowers patients to overcome this inertia. This study aims to compare the effectiveness of patient-preferred and guideline-recommended self-titration algorithms in achieving glycemic targets and improving adherence. Methods Outpatients with type 2 diabetes (T2D) who did not respond to oral antihyperglycemic drugs (OAD) were assessed. They were randomly assigned to patient-preferred and guideline-recommended groups. In the patient-preferred group, individuals selected an algorithm to self-adjust their insulin glargine dosage by 2 units every 3 days if the mean fasting blood glucose (FBG) over the past 3 consecutive days was ≥7.0 mmol/L, or by 1 unit daily if the FBG on the same day was ≥7.0 mmol/L. In the guideline-recommended group, insulin glargine was titrated by 2 units every 3 days if the mean FBG over the past 3 consecutive days was ≥7.0 mmol/L. The FBG target was set below <7.0 mmol/L. Results Thirty-nine participants in the patient-preferred group and 42 in the guideline-recommended group completed the study. The cumulative rates of achieving the FBG target in the patient-preferred group compared to the guideline-recommended group were 69.2% vs 54.8% (χ²=1.792, p=0.181) in week 1, 89.7% vs 73.8% (χ²=3.403, p = 0.065) in week 2, 94.9% vs 76.2% (χ²=17.638, p=0.000) in week 3, and 100.0% vs 88.1% (χ²=4.405, p=0.036) in week 4. Adherence rates were significantly higher in the patient-preferred group (97.4%, 37/38) compared to the guideline-recommended group (66.7%, 28/42) (χ²=12.688, p=0.000). Insulin glargine dosage at FBG target achievement was 21.2±4.3 U in the patient-preferred group and 18.8±6.7 U in the guideline-recommended group (t=1.888, p=0.063). Hypoglycemia was reported in 1 patient in the guideline-recommended group, with no instances in the patient-preferred group. Conclusion The patient-preferred self-titration algorithm demonstrates a higher rate of reaching glucose targets and improved adherence. Trial Registration Number ChiCTR2100050805.

Abstract
BACKGROUND AND AIM Basal insulin combined oral therapy consisting of insulin and oral anti-diabetic drugs (OADs) is recommended for type 2 diabetes uncontrolled on OADs. There is a lack of clear evidence and recommendations on the combined use of basal insulin analogues to more than one OADs (glimepiride plus metformin) in effective control of glycemic parameters and its safety in terms of reduced hypoglycemic events, weight gain and cardiovascular risk. In this context, a group of clinical experts discussed the utility of basal insulin combined oral therapy with metformin and glimepiride in the current era. METHODS The clinical experts discussed and provided their inputs virtually. The expert panel included clinical experts comprising endocrinologists and diabetologists from India and Nepal. RESULTS The panel thoroughly reviewed existing literature on the subject and proposed clinical evidence and practice-based guidelines. CONCLUSION These current clinical practice guidelines highlight the efficacy and safety of basal insulin combination therapy with various available basal insulins including neutral protamine hagedorn, detemir, glargine and degludec in addition to metformin and glimepiride therapy.

Clinical research of insulin glargine U300 in type 1 diabetes mellitus patients with frequent hypoglycaemia: real-world experience. ACTA ACUST UNITED AC 2021; 6:e102-e108. [PMID: 34027219 PMCID: PMC8117072 DOI: 10.5114/amsad.2021.105562] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/02/2021] [Accepted: 03/27/2021] [Indexed: 11/17/2022]
Abstract
Introduction We aimed to see whether insulin glargine U300 can provide better blood glucose control while reducing hypoglycaemia in a more homogeneous population compared to previous studies. Material and methods The retrospective study included type 1 diabetes mellitus (T1DM) patients with frequent hypoglycaemia. For evaluation of fasting blood glucose, haemoglobin glycated (HbA1c) and weight at 6 months and 12 months (final), observation windows of 120–240 days (4–8 months) and 240–480 days (9–16 months) after insulin glargine U300 initiation, respectively, were permitted. Mean follow-up time was 12 months. Hypoglycaemia was defined as blood glucose level < 70 mg/dl, either symptomatic or asymptomatic, measured in hospital or at home. Results Forty-four patients were included in the study, and 35 patients completed the study – 20 (57.1%) females and 15 (42.9%) males, with a mean age of 24.1 ±6.6 years. Mean body mass index was 24.4 ±7.4 kg/m2. A significant decrease was not found between baseline and HbA1c values at 6 months (p = 0.199), but a significant decrease was found in the final period (between 9–16 months) (p = 0.025). Hypoglycaemic events occurred in all patients (100%) before using insulin glargine U300, while the incidence of hypoglycaemic events gradually decreased to 74.3%, 68.6%, and 68.6% between months 1–3, 3–6, and 6–9, respectively. Of the 26 patients who declared their level of satisfaction, 23 (88.5%) were satisfied, 2 (7.7%) indicated that there was no significant difference, and 1 (3.8%) patient was unsatisfied. Conclusions Over 9–16 months of follow-up, insulin glargine U300 led to a significant reduction not only of HbA1c levels but also of the frequency of hypoglycaemia, and also yielded high satisfaction rates.

Abstract
Achieving target glycaemic control is essential in people with diabetes to minimize the risk of long-term complications, and many people with type 2 diabetes will ultimately require basal insulin (BI) therapy to achieve their individualized glycaemic targets. Usually, the first 12 weeks following initiation of BI therapy represents the period when the greatest dose increases and glycaemic reductions occur. Effective glycaemic control combined with minimizing the risk of hypoglycaemia is important to enable the achievement of glycaemic control in the longer term. However, substantial therapeutic inertia exists in clinical practice, both in initiation and up-titration of BI, owing to patient-, physician- and healthcare system-related barriers, including fear of hypoglycaemia and the perception of a burdensome regimen. The more prolonged duration of action, reduced glycaemic variability and lower risk of hypoglycaemia seen with second-generation versus first-generation BI analogues may help alleviate patients' and physicians' concerns and facilitate titration. In turn, optimal BI titration and subsequent metabolic benefits may help improve therapy adherence and self-management. This review details the clinical implications of prompt titration of BI to achieve early glycaemic control, and the importance of minimizing hypoglycaemia risk within the initial titration period. Facilitation of patients' self-management of BI is also addressed.

Abstract
Due to the progressive nature of type 2 diabetes (T2DM), initiation of insulin therapy is very likely in the disease continuum. This article aims at highlighting the current situation with regard to insulin therapy in people with T2DM in Europe and at presenting the associated unmet need. Challenges for both people with T2DM and healthcare professionals include clinical inertia also derived from fear of hypoglycaemia, weight gain and injections as well as increased need for a comprehensive diabetes management. We compare national and international guidelines and recommendations for the initiation and intensification of insulin therapy with the real-world situation in six European countries, demonstrating that glycaemic targets are only met in a minority of people with T2DM on insulin therapy. Furthermore, this work evaluates currently recorded numbers of people with T2DM treated with insulin in Europe, the proportion not achieving the stated glycaemic targets and thus in need to enhance insulin therapy e.g. by a change in means of insulin delivery including, but not limited to, insulin pens, wearable mealtime insulin delivery patches, patch pumps, and conventional insulin pumps with continuous subcutaneous insulin infusion.

Abstract
AIM To compare the efficacy and safety of self- versus physician-managed titration of insulin glargine 300 U/mL (Gla-300) in people with inadequately controlled type 2 diabetes. METHODS Take Control (EudraCT number: 2015-001626-42) was a 24-week, multi-national, open-label, controlled, two-arm, parallel-group study in insulin-naïve and pre-treated participants, randomized 1:1 to a self- or physician-managed titration of Gla-300. The fasting self-monitored plasma glucose (SMPG) target was 4.4 to 7.2 mmol/L. The primary outcome was non-inferiority of glycated haemoglobin (HbA1c) change from baseline to week 24. Secondary outcomes included SMPG target achievement without hypoglycaemia, hypoglycaemia incidence, adverse events and participant-reported outcomes (PROs). RESULTS At week 24, the least squares (LS) mean HbA1c reduction was 0.97% (10.6 mmol/mol) and 0.84% (9.2 mmol/mol) in the self- and physician-managed groups, respectively, with an LS mean difference of -0.13% [95% confidence interval -0.2619 to -0.0004] (-1.4 mmol/mol [-2.863 to -0.004]), demonstrating non-inferiority (P < 0.0001) and superiority (P = 0.0247) of self- versus physician-managed titration. Significantly more of the self- than physician-managed group achieved SMPG target without hypoglycaemia (67% vs 58%; P = 0.0187). Overall, hypoglycaemia incidence was similar in each group. No safety concerns were reported. In both groups, similar PRO improvements were observed for distress related to diabetes disease burden and for confidence in diabetes self-management, with even more individuals achieving a clinically relevant reduction in emotional burden and fewer individuals with high emotional burden in the self-managed group. CONCLUSIONS Self-managed titration of Gla-300 was superior to physician-managed titration in terms of HbA1c reduction, accompanied by similar total PRO scores, with a clinically relevant reduction in emotional burden, and similar hypoglycaemia frequency.

Abstract
INTRODUCTION Despite the continuously growing number of therapeutic options for patients with type 2 diabetes mellitus (T2DM), a large percentage of these individuals fail to achieve their glycated hemoglobin (HbA1c) target. The aim of this study was to determine the change in metabolic control in insulin-naïve T2DM patients inadequately controlled with oral antidiabetic drugs (OADs) at 6 months after initiating basal insulin treatment as add-on to existing OADs. METHODS This was a non-interventional prospective study conducted from June 2013 to December 2014 in 137 centers in the Czech Republic under routine clinical practice conditions. Adult patients whose diabetes was uncontrolled on their current OAD treatment (HbA1c ≥ 53 mmol/mol; Diabetes Control and Complications Trial [DCCT]-HbA1c 7%) and whose physician had decided to initiate treatment on a basal insulin regimen were documented over a 6-month period beginning from the time of initiation of basal insulin treatment. RESULTS Overall, 1426 T2DM patients were included in the study, of whom 53% were male. The mean age of the study population was 63.8 ± 10.1 years, mean body mass index was 31.5 ± 5.3 kg/m2, and mean duration of diabetes was 10.2 ± 5.3 years. At the 6-month follow-up, the target HbA1c level of 53 mmol/mol (DCCT < 7%) was achieved by 18% of patients. The mean HbA1c overall had decreased from 77.2 ± 15.1 mmol/mol (DCCT 9.21 ± 1.38%) at baseline to 63.2 ± 12.5 mmol/mol (DCCT 7.93 ± 1.14 %) at the 6-month follow-up. This difference was significant at p < 0.001. The largest mean reduction in HbA1c, i.e., 20.9 mmol/mol (DCCT 2.4 %) was observed in the group of patients with a baseline HbA1c of ≥ 9%. The mean daily basal insulin dose at 6 months was 18.8 ± 8.9 units. Symptomatic hypoglycemia was reported in 12.3% of patients, of those only one patient (0.1%) suffered from severe hypoglycemia. CONCLUSION The addition of basal insulin to the therapeutic regimen of insulin-naïve T2DM on OAD treatment resulted in an improved metabolic control of diabetes after 6 months of treatment. However, most patients did not achieve their HbA1c target, probably also due to inadequate titration of basal insulin. FUNDING Sanofi, Czech Republic.

Abstract
Objective To assess oral antihyperglycemic agents (OAHA) and/or statin treatment initiation in patients with type 2 diabetes (T2D) and time from diagnosis to both types of treatment initiation and intensification. Research design and methods We reviewed 662 retrospective medical records of patients with T2D diagnosed by 31 general practitioner or specialist sites across Mexico, Argentina, and Brazil. Demographic and clinical information was abstracted from patients’ medical records and summarized using descriptive statistics. Between-group differences were assessed with Student’s t-test for continuous variables and Fisher’s exact test for categorical variables. The starting time of each therapy (OAHA and statins, separately) was assessed using Kaplan-Meier estimates. Results At diagnosis, patients’ mean age was 53 years; 44% had hypertension, 42% were obese, and 23% had dyslipidemia. During the 2-year follow-up, 95% of patients received OAHAs but only 29% of those eligible for statins received this prescription. Mean ± SD and median (Q1, Q3) time to first OAHA was 59 ± 141 days and 1 (1, 31) day, respectively, and 230 ± 232 days and 132 (30, 406) days, respectively, for a statin. During follow-up, 51–53% of patients with HbA1c/FPG values above target did not intensify hyperglycemia treatment. Conclusion Dyslipidemia treatment in patients with T2D was delayed despite its known deleterious effect on atherosclerosis development and β-cell mass/function. Anti-hyperglycemic treatment was not intensified when targets were not attained. This prescriptive inertia needs to be corrected because attainment of HbA1c treatment goals becomes more difficult, favoring the development of diabetes complications.

Abstract
Objective Insulin glargine [300 U/mL (Gla-300)] achieved better glycemic control and reduced the risk of hypoglycemia in comparison to glargine [100 U/mL; (Gla-100)] in phase 3 trials. This is the first study to retrospectively evaluate the efficacy and safety of Gla-300 in Japanese type 1 and 2 diabetes patients in a routine clinical setting. Methods We analyzed 20 type 1 diabetes patients and 62 type 2 diabetes patients who switched from Gla-100 to the same dose of Gla-300. Sixty type 2 diabetes patients who continued the use of Gla-100 during the study were included as controls. Results At three months after switching, the HbA1c levels were decreased in the patients with type 1 diabetes, but not to a significant extent. In the type 2 diabetes patients, the HbA1c levels were significantly decreased after switching (p<0.01). In contrast, there was no change in the HbA1c levels of the type 2 diabetes patients who continued the use of Gla-100 over the same period. The BMI values of the type 1 diabetes patients tended to decrease (p=0.06) and there was a significant decrease in the BMI values of the type 2 diabetes patients (p<0.05). There was no change in the BMI values of the type 2 diabetes patients who continued the use of Gla-100. The rates of hypoglycemia and adverse events did not change during the follow-up period. Conclusion In the clinical setting, switching from Gla-100 to the same dose of Gla-300 had a favorable effect on glycemic control and body weight control in Japanese type 1 and type 2 diabetes patients, without any increase in adverse events; however, a prospective study should be performed to confirm these findings.

Abstract
BACKGROUND As the first once-daily basal insulin analog, insulin glargine 100 U/mL (Gla-100; Lantus®) rapidly evolved into the most commonly prescribed insulin therapy worldwide. However, this insulin has clinical limitations. The approval of new basal insulin analogs in 2015 has already started to alter the prescribing landscape. OBJECTIVE To review the available evidence on the clinical efficacy and safety of a more concentrated insulin glargine (recombinant DNA origin) injection 300 U/mL (Gla-300) compared to insulin Gla-100 in patients with type 1 and type 2 diabetes mellitus (T1DM and T2DM). METHODS The following electronic databases were searched: PubMed and MEDLINE (using Ovid platform), Scopus, BIOSIS, and Google Scholar through June 2016. Conference proceedings of the American Diabetes Association (2015-2016) were reviewed. We also manually searched reference lists of pertinent reviews and trials. RESULTS A total of 6 pivotal Phase III randomized controlled trials known as the EDITION series were reviewed. All of these trials (n=3,500) were head-to-head comparisons evaluating the efficacy and tolerability of Gla-300 vs Gla-100 in a diverse population with T1DM and T2DM. These trials were of 6 months duration with a 6-month safety extension phase. CONCLUSION Gla-300 was as effective as Gla-100 for improving glycemic control over 6 months in all studies, with a lower risk of nocturnal hypoglycemia significant only in insulin-experienced patients with T2DM. Overall, patients on Gla-300 required 10%-18% more basal insulin, but with less weight gain compared with Gla-100.

Abstract
Improving glycemic control across a primary care diabetes population is challenging. This article describes the development, implementation, and outcomes of the Diabetes Care Collaborative Model (DCCM), a collaborative team care process focused on promoting effective insulin use targeting patients with hyperglycemia in a patient-centered medical home model. After a pilot, the DCCM was implemented in 18 primary care practices affiliated with an academic medical center. Its implementation was associated with improvements in glycemic control and increase in insulin prescription longitudinally and across the entire population, with a >1% reduction in the proportion of glycated hemoglobin >9% at 2 years after the implementation compared with the 2 years prior ( P < .001). Facilitating factors included diverse stakeholder engagement, institutional alignment of priorities, awarding various types of credits for participation and implementation to providers, and a strong theoretical foundation using the principles of the collaborative care model.

Abstract
BACKGROUND Timely initiation and titration of basal insulin added on to oral anti-diabetic drugs contribute to better glycemic control. However, implementation of basal-supported oral therapy in China is not yet clear. This nationwide, prospective, 12-week observational study was designed to explore the current status of basal-supported oral therapy in patients with type 2 diabetes in China. METHODS Type 2 diabetic patients with inadequate glycemic control on anti-diabetic drugs who were to start basal-supported oral therapy with insulin glargine at outpatient clinics were enrolled from 134 hospitals in China. Both the decision to initiate basal insulin and insulin dose adjustment were at the physician's discretion. Fasting plasma glucose (FPG) and haemoglobin A1c were measured, and the starting dose of insulin were recorded at baseline. Self-monitored fasting capillary blood glucose and the adjusting dose of insulin were collected during the study. RESULTS A total of 11,192 out of 13,259 enrolled patients finished the 12-week study. FPG and haemoglobin A1c at basal-supported oral therapy initiation were 11.2 mmol/L and 9.4%, respectively, with insulin glargine started at 0.190 IU/kg/day. Insulin dose was increased 1.8 IU in average within 12 weeks. Fifty-nine percent of the patients achieved fasting capillary blood glucose ≤ 7.0 mmol/L. More patients achieved the glucose target in the group with lower baseline FPG level. Notable geographical differences of physicians' treatment habits in the current management of basal-supported oral therapy were also observed. CONCLUSIONS A great gap between everyday clinical practice and guidelines exists in China, reflected by the delayed initiation, slow dose titration and geographical differences of basal-supported oral therapy management. A concrete guideline of basal-supported oral therapy management is needed in the clinical application.

Abstract
Patients with long-standing type 2 diabetes mellitus (T2DM) can be clinically challenging for physicians to treat because these patients often lack sufficient β-cell function to respond to some oral glucose-lowering agents, may have profound comorbidities, and may have renal impairment that limits the use of traditional agents. These complications, in addition to older age, also increase the risk of hypoglycemia, which can be a major barrier to treatment success. Individualizing treatment targets to balance the benefits of glycemic control with risks of hypoglycemia is the first step to successfully treating these patients. Careful selection of combination therapy strategies to address limited β-cell function, renal function, and cardiovascular status, along with attention to selection of agents associated with lower risk of hypoglycemia, is important. Basal insulin analogs are often used in patients with long-standing diabetes to address insulinopenic states. Incretin-based therapies, particularly GLP-1 receptor agonists, provide postprandial control with lower risks of hypoglycemia than prandial insulin. The author discusses the management of patients with long-standing diabetes who may have limited β-cell function and require transition to insulin therapy with gradual intensification.

Abstract
AIMS To compare the efficacy and safety of new insulin glargine 300 U/ml (Gla-300) with that of glargine 100 U/ml (Gla-100) in insulin-naïve people with type 2 diabetes using oral glucose-lowering drugs. METHODS The EDITION 3 study was a multicentre, open-label, parallel-group study. Participants were randomized to Gla-300 or Gla-100 once daily for 6 months, discontinuing sulphonylureas and glinides, with a dose titration aimed at achieving pre-breakfast plasma glucose concentrations of 4.4-5.6 mmol/l (80-100 mg/dl). The primary endpoint was change in glycated haemoglobin (HbA1c) from baseline to month 6. The main secondary endpoint was percentage of participants with ≥1 nocturnal confirmed [≤3.9 mmol/l (≤70 mg/dl)] or severe hypoglycaemia from week 9 to month 6. Other measures of glycaemia and hypoglycaemia, weight change and insulin dose were assessed. RESULTS Randomized participants (n = 878) had a mean (standard deviation) age of 57.7 (10.1) years, diabetes duration 9.8 (6.4) years, body mass index 33.0 (6.7) kg/m(2) and HbA1c 8.54 (1.06) % [69.8 (11.6) mmol/mol]. HbA1c levels decreased by equivalent amounts with the two treatments; the least squares mean difference in change from baseline was 0.04 [95% confidence interval (CI) -0.09 to 0.17] % or 0.4 (-1.0 to 1.9) mmol/mol. Numerically fewer participants reported ≥1 nocturnal confirmed (≤3.9 mmol/l) or severe hypoglycaemia from week 9 to month 6 [relative risk (RR) 0.89 (95% CI 0.66 to 1.20)] with Gla-300 versus Gla-100; a significantly lower risk of hypoglycaemia with this definition was found over the 6-month treatment period [RR 0.76 (95% CI 0.59 to 0.99)]. No between-treatment differences in adverse events were identified. CONCLUSIONS Gla-300 is as effective as Gla-100 in reducing HbA1c in insulin-naïve people with type 2 diabetes, with lower hypoglycaemia risk.

Abstract
BACKGROUND Clinical inertia, failure to intensify treatment according to evidence-based guidelines, leads to prolonged, avoidable hyperglycemia in people with type 2 diabetes (T2D). This is a challenge for General Practice and Primary Care, where most people with T2D receive most of their care. Sustained, integrated translational research programs are needed to embed effective treatments in routine practice, yet many challenges exist for developing such programs. OBJECTIVES To explore challenges and facilitators to implementing a translational research program focused on insulin initiation and titration among people with T2D in general practice and to identify key factors important to support and sustain such translation research in primary care. Operationalizing a program of translational work in primary care: We describe a series of studies on insulin initiation and titration in general practice including theory and qualitative work (Phase 1), a small feasibility and acceptability pilot (Phase 2), a large scale pilot (Phase 3), and a pragmatic cluster randomized trial currently under way (Phase 4). We used mixed methods to explore practice level implementation issues, and reflective investigator discussions to explore broader research program sustainability. Challenges for translational research in primary care: Key facilitators and barriers at practice and research program levels, include: Appropriate funding structures to secure long-term capacity building and people support; Building and maintaining linkages between communities of practice, primary and secondary/tertiary care researchers, institutions, and industry partners; Strategies for engagement and support for practitioners and participants. CONCLUSION Building effective and sustainable translational research programs are critical for developing evidence-based policy that drives improved outcomes at a population level. Diverse sources of funding that support extensive and sustained trans-mural collaboration as well as engagement with practitioners, patients, and policymakers in the field are crucial.

Abstract
BACKGROUND Most people with type 2 diabetes (T2D) have glycaemic levels outside of target. Insulin is effective in improving glycaemia and most people with T2D eventually need this. Despite this, transition to insulin therapy is often delayed in primary care. OBJECTIVE To develop a model of care (Stepping Up) for insulin initiation in routine diabetes care in Australian general practice. To evaluate the model for feasibility of integration within routine general practice care. METHODS Drawing on qualitative work and normalisation process theory, we developed a model of care that included clarification of roles, in-practice systems and simple clinical tools. The model was introduced in an educational and practice system change intervention for general practitioners (GPs) and practice nurses (PNs). Five practices (seven GPs and five PNs) and 18 patients formed the feasibility study. Evaluation at 3 and 12 months explored experiences of GPs, PNs and patients. RESULTS Fourteen patients commenced insulin, with average HbA1c falling from 8.4% (68.3 mmol/mol) to 7.5% (58.5 mmol/mol) at 3 months. Qualitative evaluation highlighted how the model of care supported integration of the technical work of insulin initiation within ongoing generalist GP care. Ensuring peer support for patients and issues of clinical accountability and flexibility, managing time and resources were highlighted as important. CONCLUSIONS The Stepping Up model allowed technical care to be embedded within generalist whole-person care, supported clinicians and practice system to overcome clinical inertia and supported patients to make the timely transition to insulin. Testing of the model's effectiveness is now underway.

Abstract
Insulin therapy is an effective method for reducing blood glucose levels in patients with type 2 diabetes mellitus (T2DM), and most patients with T2DM eventually require insulin replacement to attain and preserve satisfactory glycaemic control. All patients with T2DM should be considered as potential candidates for intensive insulin treatment; however, there are certain considerations regarding replacement therapy for different types of people and special populations, such as patients with multiple comorbidities, adolescents, pregnant women and the elderly. Lowering HbA1c levels in isolation without assessing the patient as a whole is becoming redundant. HbA1c targets should be individualized to the specific patient, and insulin treatment ought to be customized accordingly. There are several questions that need to be taken into account when considering adding insulin therapy to other oral antidiabetic agents, for example, for whom and when insulin therapy is indicated and which basal insulin should be utilized. Potential barriers exist related to patients, providers and health-care systems that can delay the start of insulin therapy, and every effort should be made to identify and address these obstacles.

Abstract
Treat-to-target is a therapeutic concept that considers well defined and specific physiologic targets as aims in controlling the pathophysiology of the disease. It has been widely used in diseases that pathophysiology includes, chronic metabolic and physiological disturbances, namely rheumatic conditions, vascular medicine and diabetes. In diabetes, the availability of "gold-standard" quantitative measures like fasting plasma glucose and glycated hemoglobin make the application of treat-to-target trials especially pertinent. Treatment modalities which have used single therapeutic agents or combinations or in combination with a variety of titration algorithms and implementation protocols have broadened our understanding of diabetes management with specific reference to insulin initiation and maintenance. Treat-to-target trials have been used to investigate a wide variety of questions including efficacy, safety, effect of treatment on comorbidities and patient satisfaction, ideal mechanisms to implement insulin initiation etc. A more generalized acceptance and implementation of treat-to-target trials may finally revolutionize diabetes management by combining aspects of individual care with standard treatment protocols.

Abstract
BACKGROUND Type 2 diabetes (T2D) brings significant human and healthcare costs. Its progressive nature means achieving normoglycaemia is increasingly difficult, yet critical to avoiding long term vascular complications. Nearly one-half of people with T2D have glycaemic levels out of target. Insulin is effective in achieving glycaemic targets, yet initiation of insulin is often delayed, particularly in primary care. Given limited access to specialist resources and the size of the diabetes epidemic, primary care is where insulin initiation must become part of routine practice. This would also support integrated holistic care for people with diabetes. Our Stepping Up Program is based on a general practitioner (GP) and practice nurse (PN) model of care supported appropriately by endocrinologists and credentialed diabetes educator-registered nurses. Pilot work suggests the model facilitates integration of the technical work of insulin initiation within ongoing generalist care. METHODS This protocol is for a cluster randomized controlled trial to examine the effectiveness of the Stepping Up Program to enhance the role of the GP-PN team in initiating insulin and improving glycaemic outcomes for people with T2D. 224 patients between the ages of 18 and 80 years with T2D, on two or more oral hypoglycaemic agents and with an HbA1c ≥7.5% in the last six months will be recruited from 74 general practices. The unit of randomization is the practice.Primary outcome is change in glycated haemoglobin HbA1c (measured as a continuous variable). We hypothesize that the intervention arm will achieve an absolute HbA1c mean difference of 0.5% lower than control group at 12 months follow up. Secondary outcomes include the number of participants who successfully transfer to insulin and the proportion who achieve HbA1c measurement of <7.0%. We will also collect data on patient psychosocial outcomes and healthcare utilization and costs. DISCUSSION The study is a pragmatic translational study with important potential implications for people with T2D, healthcare professionals and funders of healthcare though making better use of scarce healthcare resources, improving timely access to therapy that can improve disease outcomes.

Mezquita Raya P, Reyes García R. Is treatment with liraglutide efficient? ACTA ACUST UNITED AC 2013; 61:202-8. [PMID: 24071060 DOI: 10.1016/j.endonu.2013.09.001] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/06/2013] [Revised: 08/07/2013] [Accepted: 09/02/2013] [Indexed: 10/26/2022]
Abstract
In the current context of limited economic and health resources, efficiency of drug treatments is of paramount importance, and their clinical effects and related direct costs should therefore be analyzed. Liraglutide is a glucagon-like peptide-1 (GLP-1) receptor agonist approved for the treatment of type 2 diabetes mellitus (T2DM) which, in addition to its normoglycemic effects, induces a significant improvement in body weight and several cardiovascular risk factors. The aim of this narrative review is to summarize the available evidence about the effects of liraglutide upon cardiovascular risk factors and how these improve its cost-effectiveness profile. Despite the relatively higher cost of liraglutide as compared to other alternative therapies, liraglutide has been shown to be cost-effective when clinical indicators and total costs associated to T2DM management are analyzed.

Abstract
AIMS This study assessed the efficacy and safety of once-daily insulin initiation using insulin detemir (detemir) or insulin glargine (glargine) added to existing metformin in type 2 diabetes (T2D). METHODS This 26-week, multinational, randomized, treat-to-target trial involved 457 insulin-naïve adults with T2D (HbA1c 7-9%). Detemir or glargine was added to current metformin therapy [any second oral antidiabetic drug (OAD) discontinued] and titrated to a target fasting plasma glucose (FPG) ≤90 mg/dl (≤5.0 mmol/l). Primary efficacy endpoint was change in HbA1c. RESULTS Mean (s.d.) HbA1c decreased with detemir and glargine by 0.48 and 0.74%-points, respectively, to 7.48% (0.91%) and 7.13% (0.72%) [estimated between-treatment difference, 0.30 (95% CI: 0.14-0.46)]. Non-inferiority for detemir at the a priori level of 0.4%-points was not established. The proportions of patients reaching HbA1c ≤ 7% at 26 weeks were 38% and 53% (p = 0.026) with detemir and glargine, respectively. FPG decreased ∼43.2 mg/dl (∼2.4 mmol/l) in both groups [non-significant (NS)]. Treatment satisfaction was good for both insulins. Hypoglycaemia, which occurred infrequently, was observed less with detemir than glargine [rate ratio 0.73 (95% CI 0.54-0.98)]. The proportions of patients reaching HbA1c ≤ 7% without hypoglycaemia in the detemir and glargine groups were 32% and 38% (NS), respectively. Weight decreased with detemir [-0.49 (3.3) kg] and increased with glargine [+1.0 (3.1) kg] (95% CI for difference: -2.17 to -0.89 kg). CONCLUSION While both detemir and glargine, when added to metformin therapy, improved glycaemic control, glargine resulted in greater reductions in HbA1c, while detemir demonstrated less weight gain and hypoglycaemia.

Abstract
INTRODUCTION Insulin degludec (IDeg) is a new basal insulin in development with a flat, ultra-long action profile that may permit dosing using a simplified titration algorithm with less frequent self-measured blood glucose (SMBG) measurements and more simplified titration steps than currently available basal insulins. METHODS This 26-week, multi-center, open-label, randomized, treat-to-target study compared the efficacy and safety of IDeg administered once-daily in combination with metformin in insulin-naïve subjects with type 2 diabetes using two different patient-driven titration algorithms: a "Simple" algorithm, with dose adjustments based on one pre-breakfast SMBG measurement (n = 111) versus a "Step-wise" algorithm, with adjustments based on three consecutive pre-breakfast SMBG values (n = 111). IDeg was administered using the FlexTouch® insulin pen (Novo Nordisk A/S, Bagsværd, Denmark), with once-weekly dose titration in both groups. RESULTS Glycosylated hemoglobin (HbA1c) decreased from baseline to week 26 in both groups (-1.09%, IDegSimple; -0.93%, IDegStep-wise). IDegSimple was non-inferior to IDegStep-wise in lowering HbA1c [estimated treatment difference (IDegSimple - IDegStep-wise): -0.16% points (-0.39; 0.07)95% CI]. Fasting plasma glucose was reduced (-3.27 mmol/L, IDegSimple; -2.68 mmol/L, IDegStep-wise) with no significant difference between groups. Rates of confirmed hypoglycemia [1.60, IDegSimple; 1.17, IDegStep-wise events/patient year of exposure (PYE)] and nocturnal confirmed hypoglycemia (0.21, IDegSimple; 0.10, IDegStep-wise events/PYE) were low, with no significant differences between groups. Daily insulin dose after 26 weeks was 0.61 U/kg (IDegSimple) and 0.50 U/kg (IDegStep-wise). No significant difference in weight change was seen between groups by week 26 (+1.6 kg, IDegSimple; +1.1 kg, IDegStep-wise), and there were no clinically relevant differences in adverse event profiles. CONCLUSION IDeg was effective and well tolerated using either the Simple or Step-wise titration algorithm. While selection of an algorithm must be based on individual patient characteristics and goals, the ability to attain good glycemic control using a simplified titration algorithm may enable patient empowerment through self-titration, improved convenience, and reduced costs.

Abstract
UNLABELLED AIM/INTRODUCTION: Subsample analysis was performed to examine whether dose optimization of insulin glargine (Lantus(®); Sanofi-Aventis K.K., Tokyo, Japan) contributed to achieving a target glycosylated hemoglobin (HbA1c) (<7.0%) by using the data from the Add-on Lantus to Oral Hypoglycemic Agents (ALOHA) study, a 24-week observational study of Japanese type 2 diabetes patients. We investigated the conditions of optimal dose titration by identifying patient background of dose-achiever and non-achiever subgroups. SUBJECTS AND METHODS The insulin-naive patients (n=3,180) were categorized into four groups depending on their HbA1c and insulin glargine dose at 24 weeks: patients with HbA1c <7.0% and dose <8.5 U/day (Group 1), HbA1c <7.0% and dose ≥8.5 U/day (Group 2), HbA1c ≥7.0% and dose <8.5 U/day (Group 3), and HbA1c ≥7.0% and dose ≥8.5 U/day (Group 4). RESULTS The greatest reduction in HbA1c was observed in Group 2 (-2.7%, P<0.001 vs. Group 3 or 4). Fasting plasma glucose (FPG) in Group 2 at 24 weeks (113.3 mg/dL) was significantly lower than in either Group 3 or 4 (135.4 mg/dL and 150.0 mg/dL, respectively; P<0.001 for both). The starting dose and the change of insulin glargine dose were significantly greater in Group 2 than in Group 3 (0.142 vs. 0.086 U/kg/day [P<0.001] and +5.0 vs. +1.1 U/day [P<0.001], respectively), whereas the baseline HbA1c levels and body mass index were comparable (9.3% vs. 9.4% and 23.5 kg/m(2) vs. 23.3 kg/m(2), respectively). CONCLUSIONS Our results suggest that appropriate starting dosage and subsequent dose adjustment are essential to achieve target HbA1c (<7%) and that the FPG level should be decreased to be 110 mg/dL or below for this achievement.

Abstract
BACKGROUND Glucagon-like peptide (GLP-1) is a neuroendocrine hormone that increases blood glucose and is a drug target for treatment of type 2 diabetes. Liraglutide, a subcutaneous, once-daily GLP-1 agonist, is approved for the treatment of type 2 diabetes in the United States and Europe. It also has been studied for weight loss. OBJECTIVE The purpose of this article is to review all of the relevant literature on the chemistry, pharmacology, pharmacokinetics, metabolism, clinical trials, safety, drug interactions, cost, and place in therapy of liraglutide. METHODS Literature searches of MEDLINE between 1969 and September 2010, International Pharmaceutical Abstracts between 1970 and September 2010, American Diabetes Association Meeting abstracts (2008-2010), and European Association for the Study of Diabetes abstracts (2008-2010) were performed using liraglutide, Victoza, and NN2211 as key terms. RESULTS Thirteen randomized controlled trials were identified and summarized. Liraglutide has been shown to increase glucose-dependent insulin release by 34% to 118% and reduce postprandial glucagon levels by 20%. Studies showed that liraglutide, as monotherapy and in combination with glimepiride, metformin, and/or rosiglitazone, lowers glycosylated hemoglobin (HbA(1c)) between 0.84% and 1.5%. Transient nausea was reported by 7% to 40% of subjects. Severe hypoglycemia-glucose <55 mg/dL-was observed by 2.5% of subjects in 1 trial. CONCLUSION Liraglutide safely and effectively reduces HbA(1c) in patients with type 2 diabetes. The most recent American Diabetes Association guidelines recommended a GLP-1 agonist along with metformin as a second-tier therapy for type 2 diabetes. Although the American Association of Clinical Endocrinologists/American College of Endocrinologists' guidelines recommended it for first-line monotherapy in patients with HbA(1c) between 6.5% and 7.5% and with metformin if HbA(1c) is between 7.6% and 8.5%, liraglutide should be considered for patients who cannot tolerate first-line agents or if an additional agent is needed to help reach target HbA(1c) goals.

Abstract
Type 2 diabetes is a major public health concern. Screening and early diagnosis followed by prompt and aggressive treatment interventions can help control progression of diabetes and its complications. Nurses are often the first healthcare team members to interact with patients and are being called on to apply their specialized knowledge, training, and skills to educate and motivate patients with diabetes about insulin use and practical ways to achieve treatment goals. Clinical nurse specialists possess specific training and skills to provide this level of care, while staff or office-based nurses may be trained by physicians to fulfill a task-specific role. This manuscript reviews the benefits of intensive glycemic control in type 2 diabetes, therapeutic goals and guidelines, advances in insulin therapy, and contribution of nurses in overcoming barriers to insulin initiation and related aspects of diabetes care. Nurses are particularly well positioned to fill the gap and improve efficiency in diabetes-related healthcare by assisting patients with insulin initiation and other aspects of glycemic self-management.

Abstract
OBJECTIVE To evaluate clinical and economic outcomes in patients with type 2 diabetes mellitus (T2DM) who failed oral anti-diabetic drug (OAD) therapy and initiated either insulin glargine with disposable pen (GLA-P) or exenatide BID (EXE). RESEARCH DESIGN AND METHODS This retrospective study used data from a large US-managed care claims database and included adult T2DM patients initiating treatment with GLA-P or EXE in 2007 or 2008. Propensity score matching was used to control observed baseline differences between treatment groups. Primary study end-points included treatment persistence, A1C, healthcare utilization, and healthcare costs during the 1-year follow-up period. RESULTS Two thousand three hundred and thirty nine patients were included in the study (GLA-P: 381; EXE: 1958); 626 patients were in the 1:1 matched cohort (54% male; mean age: 54 years; mean A1C: 9.2%). At follow-up, patients in the GLA-P group were significantly more persistent in treatment than EXE patients (48% vs 15% in persistence rate and 252 vs 144 days in persistence days; both p<0.001). GLA-P patients also had significantly lower A1C at follow-up (8.02% vs 8.32%; p=0.042) and greater A1C reduction from baseline (-1.23% vs -0.92%; p=0.038). There were no significant differences in claims-based hypoglycemia rates and overall diabetes-related healthcare utilization and cost. LIMITATIONS Since this was a retrospective analysis, causality of treatment benefits cannot be established. The study was specific to two treatments and may not generalize to other models of insulin administration. Some of the results, although statistically significant, may not be found clinically important. CONCLUSIONS In a real-world setting among T2DM patients who failed to achieve or sustain glycemic goal with OADs, initiation of GLA-P instead of EXE may be a more effective option because it was associated with greater treatment persistence, greater A1C reduction without a significantly higher rate of hypoglycemia, and similar healthcare costs.

Abstract
Type 2 diabetes mellitus (T2DM) is characterized by both insulin resistance and inadequate insulin secretion. All patients with the disease require treatment to achieve and maintain the target glycosylated hemoglobin (A1C) level of 6.5%-7%. Pharmacological management of T2DM typically begins with the introduction of oral medications, and the majority of patients require exogenous insulin therapy at some point in time. Primary care physicians play an essential role in the management of T2DM since they often initiate insulin therapy and intensify regimens over time as needed. Although insulin therapy is prescribed on an individualized basis, treatment usually begins with basal insulin added to a background therapy of oral agents. Prandial insulin injections may be added if glycemic targets are not achieved. Treatments may be intensified over time using patient-friendly titration algorithms. The goal of insulin intensification within the primary care setting is to minimize patients' exposure to chronic hyperglycemia and weight gain, and reduce patients' risk of hypoglycemia, while achieving individualized fasting, postprandial, and A1C targets. Simplified treatment protocols and insulin delivery devices allow physicians to become efficient prescribers of insulin intensification within the primary care arena.

Abstract
Insulin detemir provides prolonged, reproducible blood glucose reduction through a mechanism unique among basal insulins. It was originally studied clinically in predominantly basal + bolus regimens and found to be associated with a low risk of hypoglycaemia compared to insulin NPH, and reduced weight gain compared to other basal insulins. Insulin detemir has been increasingly studied in basal-only insulin regimens in type 2 diabetes, in which an understanding of how to optimize its use has been built incrementally. Glycaemic control and limitation of weight gain tend to be maximized by once-daily (evening) dosing, earlier initiation and careful titration to appropriate fasting glucose targets.

Abstract
BACKGROUND Evidence supporting the addition of specific insulin regimens to oral therapy in patients with type 2 diabetes mellitus is limited. METHODS In this 3-year open-label, multicenter trial, we evaluated 708 patients who had suboptimal glycated hemoglobin levels while taking metformin and sulfonylurea therapy. Patients were randomly assigned to receive biphasic insulin aspart twice daily, prandial insulin aspart three times daily, or basal insulin detemir once daily (twice if required). Sulfonylurea therapy was replaced by a second type of insulin if hyperglycemia became unacceptable during the first year of the study or subsequently if glycated hemoglobin levels were more than 6.5%. Outcome measures were glycated hemoglobin levels, the proportion of patients with a glycated hemoglobin level of 6.5% or less, the rate of hypoglycemia, and weight gain. RESULTS Median glycated hemoglobin levels were similar for patients receiving biphasic (7.1%), prandial (6.8%), and basal (6.9%) insulin-based regimens (P=0.28). However, fewer patients had a level of 6.5% or less in the biphasic group (31.9%) than in the prandial group (44.7%, P=0.006) or in the basal group (43.2%, P=0.03), with 67.7%, 73.6%, and 81.6%, respectively, taking a second type of insulin (P=0.002). [corrected] Median rates of hypoglycemia per patient per year were lowest in the basal group (1.7), higher in the biphasic group (3.0), and highest in the prandial group (5.7) (P<0.001 for the overall comparison). The mean weight gain was higher in the prandial group than in either the biphasic group or the basal group. Other adverse event rates were similar in the three groups. CONCLUSIONS Patients who added a basal or prandial insulin-based regimen to oral therapy had better glycated hemoglobin control than patients who added a biphasic insulin-based regimen. Fewer hypoglycemic episodes and less weight gain occurred in patients adding basal insulin. (Current Controlled Trials number, ISRCTN51125379.)

Abstract
Between 5 and 10% of the European population suffers from diabetes, and its prevalence is constantly rising, in Austria like in other countries. The main goals in the treatment of diabetes mellitus are the prevention of complications and organ damage, the prevention of severe hypo- and hyperglycaemia and the preservation of quality of life. Many patients with type 2 diabetes become insulin-dependent in the course of their disease. The application of a long acting insulin or insulin analogue is the simplest way of initiating an insulin therapy and is in accordance with current guidelines. Current scientific evidence shows that the use of long acting insulin analogues for type 2 diabetes; which can no longer be sufficiently controlled with oral antidiabetic agents, is simple, safe and efficacious. Thus, this treatment option should be available without any restrictions to physicians and patients in order to facilitate the beginning of an insulin regime. This position paper summarises up the current evidence concerning this subject.

Abstract
The GLP-1 analogues exenatide and liraglutide stimulate insulin secretion and inhibit glucagon output in a glucose-dependent manner, slow gastric emptying and decrease appetite. The injectable glucagon-like peptide-1 (GLP-1) receptor agonist exenatide significantly improves glycaemic control, with average reductions in HbA1c of about 1.0% point, fasting plasma glucose of about 1.4 mmol l(-1), and causes a weight loss of approximately 2-3 kg after 30 weeks of treatment. The adverse effects are transient nausea and vomiting. The long-acting once-daily human GLP-1 receptor agonist liraglutide reduces HbA1c by about 1.0-2.0% point, weight by 1-3 kg and seems to have fewer gastrointestinal side effects than exenatide. The final place of the GLP-1 receptor agonists in the diabetes treatment algorithm will be clarified when we have long-term trials with cardiovascular end-points and data illustrating the effects on the progression of type 2 diabetes.

The objective of this study was to report the outcome of home monitoring of diabetic cats by owners using a protocol aimed at achieving euglycaemia, using ultra-low carbohydrate diets (< or =10% metabolisable energy) and the insulin analogue glargine for >10 weeks and/or until remission was achieved. Fifty-five cats diagnosed with diabetes mellitus, whose owners joined the online German Diabetes-Katzen Forum, were included. An overall remission rate of 64% was achieved in the cohort. Significantly higher remission rates were observed if good glycaemic control was achieved soon after diagnosis: 84% for cats started on the protocol within 6 months of diagnosis went into remission, and only 35% for cats that began more than 6 months after diagnosis (P<0.001). Only one mild clinical hypoglycaemic episode occurred observed despite tight blood glucose control. In conclusion, intensive blood glucose control is safe and effective in diabetic cats using home monitoring and treatment with glargine.

Abstract
This article aims to provide an overview of efficacy and safety data on glucagon-like peptide-1 (GLP-1) receptor agonists and dipeptidyl peptidase-4 (DPP-4) inhibitors in the treatment of type 2 diabetes mellitus. Our goal is to differentiate the clinical profiles of GLP-1 receptor agonists and DPP-4 inhibitors, as well as the individual agents within each class. Additionally, we examine the utility of GLP-1 receptor agonists and DPP-4 inhibitors as these agents may be applied at different stages of type 2 diabetes therapy and discuss recently published clinical findings and their implications for treatment.

Abstract
BACKGROUND Many patients with type 2 diabetes (T2DM) are not able to reach the glycaemic target level of HbA1c < 7.0%, and therefore are at increased risk of developing severe complications. Transition to insulin therapy is one of the obstacles in diabetes management, because of barriers of both patient and health care providers. Patient empowerment, a patient-centred approach, is vital for improving diabetes management. We developed a web-based self-management programme for insulin titration in T2DM patients. The aim of our study is to investigate if this internet programme helps to improve glycaemic control more effectively than usual care. METHODS/DESIGN T2DM patients (n = 248), aged 35-75 years, with an HbA1c > or = 7.0%, eligible for treatment with insulin and able to use the internet will be selected from general practices in two different regions in the Netherlands. Cluster randomisation will be performed at the level of general practices. Patients in the intervention group will use a self-developed internet programme to assist them in self-titrating insulin. The control group will receive usual care.Primary outcome is the difference in change in HbA1c between intervention and control group. Secondary outcome measures are quality of life, treatment satisfaction, diabetes self-efficacy and frequency of hypoglycaemic episodes. Results will be analysed according to the intention-to-treat principle. DISCUSSION An internet intervention supporting self-titration of insulin therapy in T2DM patients is an innovative patient-centred intervention. The programme provides guided self-monitoring and evaluation of health and self-care behaviours through tailored feedback on input of glucose values. This is expected to result in a better performance of self-titration of insulin and consequently in the improvement of glycaemic control. The patient will be enabled to 'discover and use his or her own ability to gain mastery over his/her diabetes' and therefore patient empowerment will increase. Based on the self-regulation theory of Leventhal, we hypothesize that additional benefits will be achieved in terms of increases in treatment satisfaction, quality of life and self-efficacy.

Abstract
Glycoforms of glargine expressed in Pichia pastoris were isolated by high-performance liquid chromatography and analyzed by a series of chemical and mass spectrometric methods for the identification of various glycoforms, glycosylation position, nature and structure of glycans. Reduction and alkylation, peptide mapping techniques were used to decipher the amino acid site at which glycosylation had taken place. Chemical methods were coupled with mass spectrometry techniques such as electrospray ionization and matrix-assisted laser desorption/ionization for identification of the glycosylation site.

Abstract
Liraglutide is the first human glucagon-like peptide-1 receptor analog, based on the structure of native glucagon-like peptide-1 with pharmacokinetic properties suitable for once-daily dosing. In the Phase II studies and the Phase III Liraglutide Effect and Action in Diabetes (LEAD™) program, liraglutide has been shown to lower glycated hemoglobin A1c to the same degree or more than other oral antidiabetic drugs. Liraglutide also induces weight loss and improves β-cell function, blood pressure and some cardiovascular risk markers. Liraglutide is well tolerated; the adverse effect most frequently reported being transient nausea. This article reviews the Phase II studies and the Phase III LEAD™ program. In May 2008, Novo Nordisk submitted a new drug application for liraglutide to the US FDA and the EMEA.

Abstract
OBJECTIVE To assess and compare the total costs relevant to diabetes care in patients with type 2 diabetes mellitus (T2D) treated at specialised diabetes practices with either insulin glargine- or conventional basal insulin (neutral protamine Hagedorn [NPH])-based therapies from the German statutory health insurance (SHI) perspective. METHODS The Long Acting Insulin Glargine Versus NPH Cost Evaluation in Specialised Practices (LIVE-SPP) study is an observational, retrolective, multicentre longitudinal cost comparison in adults with T2D. Costs were evaluated from the German SHI perspective based on official 2005 prices. Average total costs per patient for insulin glargine-versus NPH-based therapies were compared using multivariate general linear modelling. Sensitivity analyses were performed by varying the main cost factors by +/- 25%. RESULTS Patients (n=1,024, 512 patients per cohort) were on average 62 years of age, with an average 8-year diabetes history at study start. The average unadjusted total annual costs per patient were euro 1,868.41 (95% CI 1,744.27-1,992.56) for insulin glargine-based vs. euro 2,063.72 (95% CI 1,922.91-2,204.54) for NPH-based therapies. Average adjusted total annual costs per patient between insulin glargine- (euro 1,241.13) and NPH-based therapies (euro 1,607.86) were statistically significantly different (p=0.0004). The economic advantage for insulin glargine-based therapies resulted mainly from fewer blood glucose measurements and other diabetes-related materials (e.g. needles). The savings remained stable in one-way sensitivity analyses. CONCLUSIONS The LIVE-SPP study suggests that insulin glargine-based therapies may offer an economic advantage over NPH-based therapies.
