Effect of Baseline Glycosylated Hemoglobin A1C on Glycemic Control and Diabetes Management following Initiation of Once-daily Insulin Detemir in Real-Life Clinical Practice

The SOLVE study investigated the initiation of basal insulin in patients with type 2 diabetes on oral antidiabetic (OAD) treatment and outcomes in patients with varying levels of glycemic control at baseline. This was an observational cohort study conducted in 10 countries using insulin detemir. Data were collected at 3 clinic visits (baseline, 12-week interim, and 24-week final visit). A total of 13,526 (77.9%) patients were included in the glycosylated hemoglobin A1c (HbA1c) subset analysis. Patients were grouped according to pre-insulin HbA1c values as follows: HbA1c <7.6% (n = 2,797); HbA1c 7.6-9% (n = 5,366), and HbA1c >9% (n = 5,363). A total of 27 patients experienced serious adverse drug reactions (SADRs) and/or severe hypoglycemia (3, 10, and 11 patients with pre-insulin HbA1c <7.6%, 7.6-9.0%, and >9.0%, respectively). All patient subgroups realized improvements in HbA1c, with the pre-insulin HbA1c >9% subgroup having the largest HbA1c reduction (-2.4% versus -0.9% and -0.2% for HbA1c subgroups 7.6-9% and <7.6%, respectively). In the total cohort (n = 17,374), the incidence of severe hypoglycemia decreased from 4 events per 100 person years to <1 event per 100 person years by final visit; the incidence of minor hypoglycemia increased from 1.6 to 1.8 events per person year. In this study, insulin initiation was delayed until late in disease course, and overall concordance with internationally recognized guidelines was low. The initiation of once-daily insulin detemir was associated with substantial improvements in glycemic control and was not associated with an increase in severe hypoglycemia or weight gain.

Pharmacotherapy in Type 1 Diabetes

Pharmacotherapy in Type 1 Diabetes

Once weekly exenatide: efficacy, tolerability and place in therapy

Exenatide once weekly is the first glucose-lowering agent available to patients with type 2 diabetes mellitus (T2DM) which is administered once per week. This long-acting formulation contains the same active ingredient as exenatide twice daily, except that the exenatide is encapsulated in dissolvable microspheres. Following subcutaneous injection, exenatide once weekly microspheres remain in place under the skin and slowly degrade, releasing active exenatide continuously into circulation. In randomized clinical trials, exenatide once weekly was associated with significant glycaemic improvement and moderate weight loss in patients with T2DM when administered as monotherapy or in combination with a variety of oral antidiabetic agents. Exenatide once weekly also lowered blood glucose more effectively than titrated basal insulin in patients on metformin or metformin plus sulphonylurea background therapy. Gastrointestinal side effects (nausea, vomiting and diarrhoea) were the most common tolerability issues associated with exenatide once weekly administration, but they occurred at lower rates than in patients on other glucagon-like peptide receptor agonists (i.e., exenatide twice daily or liraglutide). Issues regarding the place of exenatide once weekly in T2DM pharmacotherapy are discussed.

Efficacy and Safety of Linagliptin as Add-on Therapy to Basal Insulin in Patients With Type 2 Diabetes

This multicenter, randomized, placebo-controlled, phase 3 study evaluated the efficacy and safety of the DPP-4 inhibitor linagliptin as add-on therapy to basal insulin alone or in combination with metformin and/or pioglitazone in patients with type 2 diabetes. A total of 1261 patients inadequately controlled on insulin glargine, insulin detemir, or NPH insulin were randomized to receive either linagliptin 5 mg qd or placebo for at least 52 weeks. The primary efficacy endpoint was the mean change in A1C from baseline to Week 24, during which time the basal insulin dose remained stable. This predefined interim analysis incorporates all safety and tolerability data up to the interim timepoint (mean exposure: linagliptin, 304 days; placebo, 296 days). Mean (SD) baseline characteristics were similar in the linagliptin vs placebo groups: age, 59.7 (9.9) vs 60.4 (10.0) yrs; BMI, 30.8 (5.4) vs 31.2 (5.0) kg/m2; A1C, 8.3% (0.9%) both; basal insulin dose, 41.6 (31.9) vs 40.1 (27.3) IU/day. The placebo-adjusted mean change in A1C from baseline to Week 24 was -0.65% (p<0.0001; Figure). The overall frequency of adverse events (linagliptin, 71.8%; placebo, 72.5%) and hypoglycemia (linagliptin, 25.7%; placebo, 27.3%) were similar in both groups. Mean (SE) body weight did not change significantly from baseline (linagliptin, -0.17 (0.11) kg; placebo, +0.13 (0.12) kg; p=0.07). In conclusion, the addition of linagliptin to patients inadequately controlled on basal insulin therapy achieved significant and clinically meaningful improvements in glycemic control without weight gain and no additional risk of hypoglycemia.

Clinical Outcomes of Concomitant Therapy of Exenatide Twice Daily and Basal Insulin In Patients with Type 2 Diabetes Mellitus: A Retrospective Database Analysis In the United States

To examine the clinical effectiveness of concomitant therapy of exenatide twice daily and basal insulin in patients with type 2 diabetes mellitus in the United States. Data from adults with type 2 diabetes were selected from an electronic medical record database. Concomitant therapy was defined as a basal insulin prescription within 6 months before or after an exenatide prescription between May 2005 and April 2009. Upon initiation, patients were treated with both medications. Clinical effectiveness was measured as mean changes in hemoglobin A1c (primary outcome), body weight, body mass index, blood pressure, and lipid values from a 6-month baseline to mean-adjusted values in a 12-month follow-up period. These changes were assessed by a bootstrapping test. There were 1752 patients (mean age, 57 years) who initiated concomitant therapy (75% added exenatide to basal insulin, 25% added basal insulin to exenatide). Patients achieved significant mean reductions in hemoglobin A1c (0.5%), body weight (1.8 kg), body mass index (0.6 kg/m2), diastolic blood pressure (0.5 mm Hg), and various lipid measures (all P<.05). Hemoglobin A1c reduction was consistent irrespective of the treatment order. However, body weight, body mass index, and blood pressure reductions were observed in only patients who added exenatide to basal insulin. Overall, exenatide and basal insulin concomitant therapy was associated with significant reductions in hemoglobin A1c, body weight, body mass index, diastolic blood pressure, and lipids in a large, diverse patient population treated in ambulatory care settings in the United States. In the subgroup analysis, body weight, body mass index, and diastolic blood pressure reductions were observed in only patients who added exenatide to basal insulin.

Glucagon-like peptide-1 receptor agonists as add-on therapy to basal insulin in patients with type 2 diabetes: a systematic review

The prevalence of obesity and diabetes continues to rise in the US. Glucagon-like peptide-1 receptor agonist (GLP-1RA) is an effective treatment option for type 2 diabetes mellitus (T2DM) that promotes weight loss. Common and effective treatment options added to metformin therapy (basal insulin, sulfonylureas, and pioglitazone) contribute to weight gain, which makes the addition of GLP-1RAs advantageous. Exenatide was the first agent in this class and has recently been approved for use in combination with insulin glargine by the US Food and Drug Administration and the European Medicines Agency. Until recently, there was a lack of data examining basal insulin combined with these agents. The main purpose of this article is to review the prospective interventional data on the safety and efficacy of GLP-1RAs (exenatide, liraglutide, albiglutide, lixisenatide) combined with basal insulin therapy in nonpregnant adults with T2DM. Databases searched were PubMed, Cochrane Central Register of Controlled Trials and the Database of Systematic Reviews (inception to January 2012). s presented at relevant diabetes and endocrine meetings from 2009 to 2011 were also reviewed, as were reference lists of identified publications. A total of five studies met the criteria and were included in the review. Data from these studies demonstrated that this combination therapy offers advantages for the treatment of diabetes, such as additional lowering of A1c without major risk for hypoglycemia, lower basal insulin requirements, decreased postprandial glucose levels (with or without fasting plasma glucose decreases), and weight loss, or at the very least, less weight gain. However, the gastrointestinal side effects and high cost of these agents may limit their use. This review demonstrates that adding a GLP-1RA to an existing basal insulin regimen is a reasonable treatment strategy in nonpregnant adult patients with T2DM.

Insulin glargine versus sitagliptin in insulin-naive patients with type 2 diabetes mellitus uncontrolled on metformin (EASIE): a multicentre, randomised open-label trial

In people with type 2 diabetes, a dipeptidyl peptidase-4 (DPP-4) inhibitor is one choice as second-line treatment after metformin, with basal insulin recommended as an alternative. We aimed to compare the efficacy, tolerability, and safety of insulin glargine and sitagliptin, a DPP-4 inhibitor, in patients whose disease was uncontrolled with metformin. In this comparative, parallel, randomised, open-label trial, metformin-treated people aged 35-70 years with glycated haemoglobin A(1c) (HbA(1c)) of 7-11%, diagnosis of type 2 diabetes for at least 6 months, and body-mass index of 25-45 kg/m(2) were recruited from 17 countries. Participants were randomly assigned (1:1) to 24-week treatment with insulin glargine (titrated from an initial subcutaneous dose of 0·2 units per kg bodyweight to attain fasting plasma glucose of 4·0-5·5 mmol/L) or sitagliptin (oral dose of 100 mg daily). Randomisation (via a central interactive voice response system) was by random sequence generation and was stratified by centre. Patients and investigators were not masked to treatment assignment. The primary outcome was change in HbA(1c) from baseline to study end. Efficacy analysis included all randomly assigned participants who had received at least one dose of study drug and had at least one on-treatment assessment of any primary or secondary efficacy variable. This trial is registered at ClinicalTrials.gov, NCT00751114. 732 people were screened and 515 were randomly assigned to insulin glargine (n=250) or sitagliptin (n=265). At study end, adjusted mean reduction in HbA(1c) was greater for patients on insulin glargine (n=227; -1·72%, SE 0·06) than for those on sitagliptin (n=253; -1·13%, SE 0·06) with a mean difference of -0·59% (95% CI -0·77 to -0·42, p<0·0001). The estimated rate of all symptomatic hypoglycaemic episodes was greater with insulin glargine than with sitagliptin (4·21 [SE 0·54] vs 0·50 [SE 0·09] events per patient-year; p<0·0001). Severe hypoglycaemia occurred in only three (1%) patients on insulin glargine and one (<1%) on sitagliptin. 15 (6%) of patients on insulin glargine versus eight (3%) on sitagliptin had at least one serious treatment-emergent adverse event. Our results support the option of addition of basal insulin in patients with type 2 diabetes inadequately controlled by metformin. Long-term benefits might be expected from the achievement of optimum glycaemic control early in the course of the disease. Sanofi.

Insulin degludec, an ultra-longacting basal insulin, versus insulin glargine in basal-bolus treatment with mealtime insulin aspart in type 1 diabetes (BEGIN Basal-Bolus Type 1): a phase 3, randomised, open-label, treat-to-target non-inferiority trial

Intensive basal-bolus insulin therapy has been shown to improve glycaemic control and reduce the risk of long-term complications that are associated with type 1 diabetes mellitus. Insulin degludec is a new, ultra-longacting basal insulin. We therefore compared the efficacy and safety of insulin degludec and insulin glargine, both administered once daily with mealtime insulin aspart, in basal-bolus therapy for type 1 diabetes. In an open-label, treat-to-target, non-inferiority trial, undertaken at 79 sites (hospitals and centres) in six countries, adults (aged ≥18 years) with type 1 diabetes (glycated haemoglobin [HbA(1c)] ≤10% [86 mmol/mol]), who had been treated with basal-bolus insulin for at least 1 year, were randomly assigned in a 3:1 ratio, with a computer-generated blocked allocation sequence, to insulin degludec or insulin glargine without stratification by use of a central interactive response system. The primary outcome was non-inferiority of degludec to glargine, assessed as a reduction in HbA(1c) after 52 weeks, with the intention-to-treat analysis. This trial is registered with ClinicalTrials.gov, number NCT00982228. Of 629 participants, 472 were randomly assigned to insulin degludec and 157 to insulin glargine; all were analysed in their respective treatment groups. At 1 year, HbA(1c) had fallen by 0·40% points (SE 0·03) and 0·39% points (0·07), respectively, with insulin degludec and insulin glargine (estimated treatment difference -0·01% points [95% CI -0·14 to 0·11]; p<0·0001 for non-inferiority testing) and 188 (40%) and 67 (43%) participants achieved a target HbA(1c) of less than 7% (<53 mmol/mol). Rates of overall confirmed hypoglycaemia (plasma glucose <3·1 mmol/L or severe) were similar in the insulin degludec and insulin glargine groups (42·54 vs 40·18 episodes per patient-year of exposure; estimated rate ratio [degludec to glargine] 1·07 [0·89 to 1·28]; p=0·48). The rate of nocturnal confirmed hypoglycaemia was 25% lower with degludec than with glargine (4·41 vs 5·86 episodes per patient-year of exposure; 0·75 [0·59 to 0·96]; p=0·021). Overall serious adverse event rates (14 vs 16 events per 100 patient-years of exposure) were similar for the insulin degludec and insulin glargine groups. Insulin degludec might be a useful basal insulin for patients with type 1 diabetes because it provides effective glycaemic control while lowering the risk of nocturnal hypoglycaemia, which is a major limitation of insulin therapy.

Weight Beneficial Treatments for Type 2 Diabetes

The close link between type 2 diabetes and excess body weight highlights the need to consider the weight effects of different treatment regimens. We examine the impact of "weight-friendly" type 2 diabetes pharmacotherapies and suggest treatment strategies that mitigate weight gain. Evidence was identified via PubMed search by class and agent and in bibliographies of review articles, with final articles for inclusion selected by author consensus. Substantial evidence confirms the weight benefits of metformin and shows that, of the newer available agents, glucagon-like peptide-1 (GLP-1) agonists and amylin analogs promote weight loss. Dipeptidyl peptidase-4 (DPP-4) inhibitors and bile acid sequestrants are weight-neutral. Liraglutide and exenatide appear to have similar effects on weight; however, recent research suggests a potentially greater effect of liraglutide on glycemic control compared to exenatide, when used as a second-line therapy. Mounting evidence suggests that insulin detemir may provide the most favorable weight benefits of available insulins. Weight-beneficial agents should be considered in patients, particularly obese patients, who fail to reach glycemic targets on metformin therapy. We propose the following treatment choices based on potential weight benefit and blood glucose increment: long-acting GLP-1 agonists (liraglutide), DPP-4 inhibitors, bile acid sequestrants, amylin analogs, and basal insulin for patients with elevated fasting plasma glucose; and short-acting (exenatide) or long-acting GLP-1 agonists, amylin analogs, DPP-4 inhibitors, acarbose, and bile acid sequestrants for patients with elevated postprandial glucose. The weight-sparing effects of insulin detemir, notably in patients with high body mass index, should also be considered when initiating insulin therapy.

Meal-induced increases in C-reactive protein, interleukin-6 and tumour necrosis factor α are attenuated by prandial + basal insulin in patients with Type 2 diabetes.

AimTo determine if a regimen with prandial + basal insulin compared with basal insulin attenuates post-meal inflammatory and glycative biomarkers in patients with Type 2 diabetes.MethodsThis test-meal sub-study in the USA is from a previously reported clinical trial comparing the effect on glycaemic control of 24 weeks of thrice-daily pre-meal insulin lispro mix 50 (50% insulin lispro, 50% insulin lispro protamine suspension) or bedtime insulin glargine, both plus metformin. In the sub-study, glucose, insulin, triglycerides, high-sensitivity C-reactive protein, tumour necrosis factor α, interleukin-6, methylglyoxal and 3-deoxyglucosone were measured during the post-meal period of a mixed-meal breakfast at the final visit. Prandial + basal (n = 25) and basal (n = 21) insulin were administered at the same times as during the previous 24 weeks.ResultsPost-meal, the prandial + basal insulin group had significantly higher insulin, lower glucose and triglycerides, as well as lower high-sensitivity C-reactive protein, tumour necrosis factor α and interleukin-6, than the basal insulin group. Glucose incremental area under the concentration curve significantly correlated with high-sensitivity C-reactive protein, tumour necrosis factor α, interleukin-6, methylglyoxal and 3-deoxyglucosone incremental area under the concentration curve. Insulin incremental area under the concentration curve correlated inversely with high-sensitivity C-reactive protein and tumour necrosis factor α incremental area under the concentration curve. However, after adjusting for glucose incremental area under the concentration curve, these inverse correlations were no longer significant. Triglyceride incremental area under the concentration curve was not correlated with any biomarker incremental area under the concentration curve.ConclusionsControlling post-meal hyperglycaemia with prandial + basal insulin in patients with Type 2 diabetes attenuates meal-induced increases in high-sensitivity C-reactive protein, interleukin-6 and tumour necrosis factor α compared with basal insulin. The rise in post-meal glucose, but not triglycerides, significantly correlated with the rise in post-meal inflammatory and glycative biomarkers.

First insulinization with basal insulin in patients with Type 2 diabetes in a real-world setting in Asia

Background:The First Basal Insulin Evaluation (FINE) Asia study is a multinational, prospective, observational study of insulin-naïve Type 2 diabetes mellitus (T2DM) patients in Asia, uncontrolled (A1c ≥ 8%) on oral hypoglycemic agents, designed to evaluate the impact of basal insulin initiation.Methods:Basal insulin was initiated with or without concomitant oral therapy and doses were adjusted individually. All treatment choices, including the decision to initiate insulin, were at the physician's discretion to reflect real-life practice.Results:Patients (n= 2679) from 11 Asian countries were enrolled (mean [±SD] duration of diabetes 9.3 ± 6.5 years; weight 68.1 ± 12.7 kg; A1c 9.8 ± 1.6%). After 6 months of basal insulin (NPH insulin, insulin glargine, or insulin detemir), A1c decreased to 7.7 ± 1.4%; 33.7% patients reached A1c <7%. Fasting blood glucose (FBG) decreased from 11.7 ± 3.6 to 7.2 ± 2.5 mmol/L and 36.8% of patients reached FBG <6.1 mmol/L. The mean daily insulin dose prescribed increased marginally from 0.18 to 0.23 U/kg per day at baseline to 0.22–0.24 U/kg per day at Month 6. Mean changes in body weight and reported rates of hypoglycemia were low over the duration of the study.Conclusions:Initiation of insulin therapy is still being delayed by approximately 9 years, resulting in many Asian patients developing severe hyperglycemia. Initiating insulin treatment with basal insulin was effective and safe in Asian T2DM patients in a real-world setting, but insulin needs may differ from those in Western countries.

Double-blind, randomized, multicentre, and active comparator controlled investigation of the effect of Pioglitazone, Metformin, and the combination of both on cardiovascular risk in patients with type 2 diabetes receiving stable basal insulin therapy: the PIOCOMB study

BackgroundWe analyzed specific effects of an add-on therapy with pioglitazone compared to metformin and their combination in patients with basal insulin treatment on biomarkers of CV risk.MethodsIn this double-blind, randomized, multicentre, active comparator controlled trial, 121 patients with type 2 diabetes were enrolled. Inclusions: treatment with basal insulin, HbA1C 6.5% - 8.5%, age 30 - 75 years. After glargine therapy over 2 weeks for titration towards FBG ≤ 7.8 mmol/L, patients received either (A) bid 850 mg metformin (n = 42), (B) bid 15 mg pioglitazone (n = 40), or (C) 30 mg pioglitazone plus 1.7 g metformin (n = 39) over 6 months. Matrix Metal Proteinase 9 (MMP-9) was primary objective, together with biomarkers of CV risk.ResultsPioglitazone (B) reduced MMP-9 versus baseline by 54.1 + 187.1 ng/mL, with metformin (A) it was increased by 49.6 + 336.2 ng/mL (p = 0.0345; B vs. A), and with the combination of both (C) it was decreased by 67.8 + 231.4 ng/mL (A vs. C: p = 0.0416; B vs. C: p = 0.8695). After logarithmic transformation due to high variances the exploratory results showed significance for A vs. B (p = 0.0043) and for A vs. C (p = 0.0289).Insulin dosage was reduced by 7.3 units in group B (p < 0.0001), by 6.0 units in C (p = 0.0004), but was increased by 2.5 units (p = 0.1539) in A at follow up. Reduction in hs-CRP was significant within treatment groups for B (p = 0.0098) and C (p < 0.0001), and between the groups for A vs. C (p = 0.0124). All three single regimens reduced PAI-1. Adiponectin was significantly elevated in B and C (p < 0.0001) and between-groups. HbA1C was only significantly decreased in the combination group. No significant effects were observed for NFkB and PGFα. peripheral edema were seen in 11.9% vs. 40.0% vs. 20.5%, and weight change was -0.7 kg vs. +4.3 kg vs. +2.7 kg (A vs. B vs. C).ConclusionsAddition of pioglitazone but not of metformin reduces MMP-9, hs-CRP and increased insulin sensitivity and adiponectin in this study. The combination of both had no additional effect on inflammation. Pioglitazone is suggested to be a rational add-on therapy to basal insulin in patients with high CV risk.

Glycemic Control with Preprandial Versus Basal Insulin in Patients with Type 2 Diabetes Mellitus Poorly Controlled by Oral Antidiabetes Agents

This study was designed to compare glycemic control (glycated hemoglobin [A1C] level) with either once-daily basal insulin (BI) (insulin glargine) or preprandial insulin (PPI) (Exubera) [insulin human (recombinant DNA origin)] inhalation powder, Pfizer Inc., New York, NY) in patients with type 2 diabetes mellitus (T2DM) poorly controlled on at least two oral antidiabetes agents (OADs). This was a 26-week, open-label, parallel-group, randomized study where 257 patients (mean A1C 8.6%) on OAD treatment for > or = 3 months were treated with either BI (n = 122) or PPI (n = 135). Based on self-monitored blood glucose levels, PPI dose was adjusted before each major meal, whereas BI dose was titrated in the morning or before bedtime. Prestudy OADs were continued, but doses could be modified. At 26 weeks, change from baseline in A1C was greater with PPI (-1.7 vs. -1.4%, P = 0.0389). Numerically, more patients achieved A1C <6.5% (28% vs. 19%) and A1C <7.0% (63% vs. 55%) with PPI compared with BI. PPI had lower postmeal glucose increments, but higher prebreakfast glucose and weight gain (1.1kg), than BI. Mild or moderate hypoglycemic events were more frequent with PPI (6.2 vs. 2.9 events/months), but nocturnal hypoglycemic events were less frequent (22% vs. 30%). PPI improved postprandial glucose and A1C levels significantly more than BI. More patients achieved A1C targets with PPI, at the expense of more hypoglycemia and body weight gain. These results illustrate the potential benefits and detriments of prandial insulin supplementation in patients with T2DM poorly controlled on OADs alone.

Can simple intensification of therapy with modern two-phase insulin help in type 2 diabetes when target glycemia failed to be achieved withbasal insulin? Results of subanalysis in the PRESENT study

Aim. To evaluate efficiency and safety of intensification of therapy by substituting two-phase insulin aspart 30 (DiAsp 30) for basal insulin in patients with type2 diabetes mellitus after a failure to achieve target glycemia. Materials and methods. Analysis of the data obtained in a group of patients involved in the PRESENT study (Physicians Routine Evaluation of Safety andEfficacy of NovoMix 30 Therapy), a 6 month-long observational study conducted in 15 countries. The subanalysis included patients previously treated with along-acting insulin analog (AB, n=34) or intermediate and long-acting human basal insulin (HB, n=3414) and transferred thereafter to DiAsp 30 therapy.End-points of efficiency were the difference between blood HbА1c and glucose (fasting and postprandial) levels measured at the onset of the study and upon itscompletion, the number of hypoglycemic episodes and adverse events, physician and patients content with the results of the treatment. End-points were consideredseparately with reference to preceding basal therapy (AB or HB). Results. Treatment with DiAsp 30 for 6 months resulted in a fall of HbА1c levels compared with initial values (-1,60 and -142% in AB and HB patients respectively,p

When a unit of insulin is not a unit: Detemir dosing and insulin cost in type 2 diabetes mellitus

Background: Increasing acceptance of basal-bolus insulin therapy for the control of diabetes mellitus (DM) has led to newer formulations of basal insulin analogues. The newest one is detemir. Objectives: Clinical evidence suggests that patients with type 2 DM require higher doses of detemir than other basal insulins to achieve equivalent glycemic control. This study examines evidence for greater dosing requirements and the implications of higher doses on the cost of insulin treatment. Methods: We performed a MEDLINE search for randomized, prospective studies comparing detemir with other basal insulins in patients with type 2 DM that were published in English between January 2000 and November 2008. The mean daily doses of basal and bolus insulin and the mean total daily insulin doses were determined. Overall weighted mean doses of the insulins were used to estimate the mean total daily insulin doses required for a 100-kg patient, and published 2008 US retail prices were used to estimate the retail costs of basal-bolus and basal-only insulin regimens. Results: Seven trials involving 3311 patients were identified in the literature search. The mean total daily insulin dose was 0.80 unit/kg for detemir-based regimens and 0.58 unit/kg for comparison regimens. For basal-bolus regimens, the estimated retail cost of the mean total daily insulin dose was $11.24 for detemir-based regimens compared with $8.99 for glargine-based regimens and $6.41 for neutral protamine Hagedorn (NPH)-based insulins. For basal-only regimens, the estimated retail cost of the mean total daily insulin dose was $8.23 for detemir compared with $5.19 for glargine and $2.35 for NPH. Conclusions: It is important for health care providers and patients to know that patients with type 2 DM may require substantially higher doses of detemir than other basal insulins. This should be considered when titrating the dose as well as in cost-benefit analyses of detemir versus other insulins.

Average daily dose of analog basal insulins in patients with type 2 diabetes: a matched case control analysis

Mealtime 50/50 basal + prandial insulin analogue mixture with a basal insulin analogue, both plus metformin, in the achievement of target HbA 1c and pre- and postprandial blood glucose levels in patients with type 2 diabetes: A multinational, 24-week, randomized, open-label, parallel-group comparison

Background: In people without diabetes, ∼50% of daily insulin secretion is basal and the remainder is postprandial. Hence, it would be expected that insulin replacement therapy in a 50/50 ratio with each meal would mimic physiologic insulin secretion better than treatment with once-daily basal insulin in patients with diabetes mellitus. Using lispro mix (LM) 50/50 before meals may be a logical approach to achieving glycemic targets (glycosylated hemoglobin [HbA lc] and pre- and postprandial blood glucose [BG] concentrations) in these patients. Objective: The aim of this study was to test the hypothesis that treatment with a premixed insulin analogue containing 50/50 basal + prandial insulins administered before each meal would achieve lower overall and mealtime glycemic control than once-daily basal insulin analogue, both plus metformin (Met), in patients with type 2 diabetes mellitus. Methods: This 24-week, randomized, open-label, parallel-group trial was conducted at 38 sites across Australia, Greece, India, The Netherlands, Poland, Puerto Rico, and the United States. Male and female patients aged 35 to 75 years with type 2 diabetes mellitus and an HbA 1c level of 6.5% to 11.0%, who were receiving metformin and/or a sulfonylurea with a stable dose of 0 to 2 daily insulin injections over the previous 3 months were eligible. Patients were randomly assigned to receive LM50/50 (50% insulin lispro protamine suspension [ILPS] and 50% lispro) TID plus metformin (to a maximally tolerated daily dosage of 500-1000 mg BID) (LM50/50 + Met) or insulin glar-gine QD at bedtime plus metformin (500-1000 mg BID) (G + Met) for 24 weeks. With LM50/50 + Met, the insulin dose was titrated to target a fasting BG (FBG) level of <6.7 mmol/L (<120 mg/dL) and a 2-hour post-prandial BG (PPBG) level of <8.0 mmol/L (<144 mg/dL)
