Dulaglutide is a new once-weekly glucagon-like peptide-1 receptor agonist for the management of hyperglycemia in adult patients with type 2 diabetes. It stimulates dose-dependent insulin secretion and reduces glucagon secretion, both in a glucose-dependent manner. Efficacy on blood glucose control and safety were demonstrated in the large AWARD program in type 2 diabetic patients treated with diet, metformin, dual oral therapy or insulin lispro with or without metformin, confirming findings of pilot studies in Caucasian patients and data in Japanese patients. Dulaglutide 1.5 mg once weekly was superior to metformin, sitagliptin, insulin glargine and exenatide twice daily, and non-inferior to liraglutide 1.8 mg once daily regarding the reduction in glycated hemoglobin. A modest but significant weight loss was consistently observed. Most frequent adverse events were transient and generally mild gastrointestinal disturbances. Clinical outcomes of dulaglutide will not be known until the large prospective cardiovascular outcome trial REWIND is complete. [less ▲]Detailed reference viewed: 14 (1 ULg)

INTRODUCTION: Insulin secretory defects are a key feature in the pathophysiology of type 2 diabetes (T2D). Classical insulin-secreting agents such as sulfonlyureas stimulate insulin secretion independent of glucose and cause hypoglycemia. Despite the advantages offered by incretin-based therapies, there is still a medical need for developing new insulin secretagogues for treating T2D. AREA COVERED: This article discusses: the new advances in the field of incretin-based therapies, glucokinase (GK) activators, free fatty acid receptor (FFAR) or G protein-coupled receptor (GPR) agonists (GPR40, GPR119, GPR120), imeglimin and some other insulin secretagogues with diverse mechanisms of action still in preclinical development. EXPERT OPINION: New insulin secretagogues should offer major advantages over sulfonylureas and gliptins. The challenge is to avoid uncontrolled insulin secretion and minimize the risk of hypoglycemia, to protect cells from progressive loss of mass and function for a better durability of glucose control, and to offer a good safety profile. Numerous approaches are in development. However, it is too early to decide whether one new pharmacological class will emerge as a clinically useful insulin secretagogue in the near feature.

Summary Because of the deleterious role attributed to insulin resistance, insulin sensitizing agents should theoretically reduce the incidence of cardiovascular complications in type 2 diabetes. In the UKPDS, metformin reduced the risk of myocardial infarction and cardiovascular mortality in a rather small group of recently diagnosed patients at a low cardiovascular risk. These results deserve confirmation in a larger study with patients a high cardiovascular risk. Glitazones, as more specific insulin sensitizers, raised much hope. However, rosiglitazone fell from its pedestal after the suspicion of an increased risk of myocardial infarction. In PROactive among patients at high cardiovascular risk, pioglitazone gave positive but questionable results: statistical significance was not reached regarding the large composite primary endpoint, but well regarding the prespecified more focused principal secondary endpoint or in various post-hoc analyses. Thus, even if data with insulin sensitizers appear globally rather promising, evidence is rather weak, therefore leading to recurrent controversy. [less ▲]Detailed reference viewed: 28 (4 ULg)

Summary : Dipeptidyl peptidase-4 (DPP-4) inhibitors (gliptins) are more and more prominent medications in the management of type 2 diabetes (T2D), with five molecules commercialized and as many fixed-dose combinations with metformin. After failure of metformin monotherapy, gliptins compete with old medications such as sulphonylureas, on the one hand, or with new oral antidiabetic agents such as inhibitors of renal sodium-glucose cotransporters type 2 (SGLT2) (gliflozines), on the other hand. Another alternative is the use of an incretin mimetic (agonist of glucagon-like peptide-1 receptors, to be injected subcutaneously) rather than an incretin enhancer such as a gliptin, before considering insulin therapy. This article analyses the arguments in favour of DPP-4 inhibitors. We will mainly consider the use of gliptins in patients with recently diagnosed T2D, in elderly and frail patients and in those with chronic kidney disease. To illustrate the discussion, we will analyze the results of both interventional and observational studies with vildagliptin. Obviously, these various groups of patients represent a large proportion of T2D population. [less ▲]Detailed reference viewed: 42 (2 ULg)

Summary : EMPA-REG OUTCOME is an international, prospective, placebo-controlled clinical trial investigating the cardiovascular outcomes of empagliflozin, an inhibitor of sodium-glucose cotransporters type 2 (SGLT2), in patients with type 2 diabetes mellitus and known cardiovascular disease. The trial succeeded in reaching the primary objective of non-inferiority and, in addition, showed, after a median follow up of 3.1 years, a superiority of empagliflozin (10 or 25 mg/day) versus placebo as regards the primary composite cardiovascular endpoint (hasard ratio or HR = 0.86; 95% CI 0.74-0.99; P = 0.04), hospitalisations for heart failure (- 35 %), cardiovascular mortality (- 38 %) and all-cause mortality (- 32 %, each p< 0.001). The reduction in mortality appeared early (< 6 months) and concerned all subgroups, without any obvious heterogeneity. This reduction in mortality does not seem to be fully explained by the concomitant slight reductions in HbA1c, body weight, waist circumference, blood pressure and serum uric acid levels in the empagliflozin groups versus the placebo group. Finally, the tolerance and safety profile of empagliflozin was good, with only a moderate increase in benign mycotic genital infections, a well-known adverse event with SGLT2 inhibitors. The remarkable effects of empagliflozin in the EMPA-REG OUTCOME trial, especially on mortality, should modify the management of patients with type 2 diabetes and a high cardiovascular risk in a near future.

Summary : Insulin lispro (Humalog®) was the first short-acting insulin analogue to be indicated for the treatment of diabetes mellitus requiring insulin therapy. After subcutaneous injection, insulin lispro has a more favourable pharmacokinetics/pharmacodynamics profile than human insulin, characterized by a faster resorption and a more rapid and less prolonged glucose-lowering activity. These properties allow a better control of postprandial hyperglycaemia and a reduction of the risk of delayed hypoglycaemia, especially at night. The patient’s quality of life is also improved because insulin lispro can be injected within the 15 minutes before meal and even possibly after meal when the amount of food intake is unpredictable. Already commercialized as Humalog® 100 U/ml, insulin lispro is now also available as Humalog® 200 U/ml. A pharmacokinetics/pharmacodynamics study confirmed the bioequivalence of the two formulations, based upon the analysis of both plasma free insulin concentrations and glucose infusion rates to maintain normoglycaemia. Humalog® 200 U/ml is available in a novel disposable 3 ml pen (KwikPenTM), with lower glide force and injection volume; thus this new pen is more convenient for the patient compared with the current pen used to inject Humalog® 100 U/ml. The new formulation Humalog® 200 U/ml is indicated in Europe for adult patients with type 1 or type 2 diabetes who require more than 20 units of prandial insulin per day to cover their meals.

Summary : The cardiovascular safety of sitagliptin has been evaluated in TECOS («Trial Evaluating Cardiovascular Outcomes with Sitagliptin»). TECOS recruited patients with type 2 diabetes and a history of cardiovascular disease who received, as add-on to their usual therapy, either sitagliptin (n = 7.257) or placebo (n = 7.266), with a median follow-up of 3 years. The primary cardiovascular outcome was a composite of cardiovascular death, nonfatal myocardial infarction, nonfatal stroke, or hospitalization for unstable angina. Sitagliptin was noninferior to placebo for the primary composite cardiovascular outcome (hazard ratio, 0.98; 95 % confidence interval, 0.88 to 1.09; P<0.001). Rates of hospitalization for heart failure did not differ between the two groups (hazard ratio, 1.00; 95 % CI, 0.83 to 1.20; P=0.98). The cardiovascular safety of sitagliptin, which was already shown in meta-analyses of phase II-III randomised controlled trials and in observational cohort studies in real life, is now confirmed in the landmark prospective cardiovascular outcome study TECOS.

INTRODUCTION: Type 2 diabetes is a complex disease with multiple defects, which generally requires a combination of several pharmacological approaches to reach glucose control targets. A unique fixed-dose combination combines a thiazolidinedione (pioglitazone) and a dipeptidyl peptidase-4 inhibitor (alogliptin). Area covered: An extensive literature search was performed to analyze the pharmacokinetics of pioglitazone and alogliptin when used separately and in combination as well as to summarize clinical and toxicological considerations about the combined therapy. Expert opinion: Pioglitazone, a potent insulin sensitizer, and alogliptin, an incretin-based agent that potentiates post-meal insulin secretion and reduces glucagon secretion, have complementary mechanisms of action. The clinical efficacy of a combined therapy is superior to any single therapy in patients treated with diet or with metformin (with or without sulphonylurea). These two drugs can be administered once daily, with or without a meal. No clinically relevant pharmacokinetic interactions between the two agents have been described and the fixed-dose combination has shown bioequivalence with alogliptin and pioglitazone given separately. Combining alogliptin with pioglitazone does not alter the safety profile of each compound. Weight gain observed with pioglitazone may be limited with the addition of alogliptin. The concern of an increased risk of heart failure remains to be better investigated. [less ▲]Detailed reference viewed: 36 (6 ULg)

Introduction: Dipeptidyl peptidase-4 (DPP-4) inhibitors (gliptins) occupy an increasing place in the armamentarium of drugs used for the management of hyperglycaemia and offer new opportunities for a personalized medicine in patients with Type 2 diabetes. Areas covered: An updated review providing an analysis of available recent data with commercialized DPP-4 inhibitors, with a special focus on: differences between the various molecules, novelties regarding their mechanism of action, clinical efficacy in mono- and various combined therapies, comparison with other new therapies, efficacy-safety profile in at risk patients, concern about pancreatic safety, perspectives in cardiovascular prevention and, finally, a selection of remaining unanswered important questions for the clinician. Expert opinion: DPP-4 inhibitors offer various advantages when compared to other glucose-lowering agents. Despite they have been commercialized since a few years only, available data obtained in randomised controlled trials are of better quality compared to those available with ancient classical glucose-lowering agents, especially in more fragile populations such as elderly people, individuals with renal impairment or at high cardiovascular risk and patients at higher risk of hypoglycaemia. However, there remain uncertainties and controversies that should be resolved by further ongoing large prospective controlled trials and increasing clinical experience combined with a careful post-marketing surveillance.

OBJECTIVES: A growing body of evidence emerges that obesity, metabolic syndrome, type 2 diabetes and cardiovascular disease are intimately related to chronic inflammation. METHODS: A narrative review summarizing the most recent data of the literature describing the pathological implications of inflammation in obese patients with cardiometabolic disorders. RESULTS: Besides high-sensitive C-reactive protein, various circulating or in situ inflammatory markers have been identified, presumably reflecting the presence of inflammation in various key-organs (visceral adipose tissue, skeletal muscle, pancreatic islets, liver, intestine, arterial wall). Available data support the concept that targeting inflammation, not only reduces systemic inflammatory markers, but also improves insulin sensitivity and ameliorates glucose control in insulin-resistant patients, thus potentially reducing the risk of cardiovascular complications. CONCLUSION: These observations confirm the role of inflammation in cardiometabolic diseases and support the development of pharmacological strategies that aim at reducing inflammation, especially in patients with type 2 diabetes.

A growing body of evidence is emerging to show that abdominal obesity, the metabolic syndrome, type 2 diabetes, cardiovascular disease and microvascular diabetic complications are intimately related to chronic inflammation. These observations pave the way to the development of new pharmacological strategies that aim to reduce silent inflammation. However, besides specific anti-inflammatory agents, glucose-lowering medications may also exert anti-inflammatory effects that could contribute to improved outcomes in diabetic patients. Most studies have used metformin, an AMP-activated protein kinase (AMPK) activator, and thiazolidinediones (TZDs), which act as peroxisome proliferator-activated receptor-gamma (PPARgamma) agonists. Both pharmacological classes (considered insulin-sparing agents or insulin sensitizers) appear to have greater anti-inflammatory activity than insulin-secreting agents such as sulphonylureas or glinides. In particular, TZDs have shown the widest range of evidence of lowered tissue (visceral fat and liver) and serum inflammation. In contrast, despite reducing postprandial hyperglycaemia, the effect of alpha-glucosidase inhibitors on inflammatory markers appears rather modest, whereas dipeptidyl peptidase-4 (DPP-4) inhibitors (gliptins) and glucagon-like peptide-1 (GLP-1) receptor agonists appear more promising in this respect. These incretin-based therapies exert pleiotropic effects, including reports of anti-inflammatory activity. No human data are available so far regarding sodium-glucose cotransporter type 2 (SGLT2) inhibitors. Although they may have indirect effects due to reduced glucotoxicity, their specific mode of action in the kidneys does not suggest systemic anti-inflammatory activity. Also, in spite of the complex relationship between insulin and atherosclerosis, exogenous insulin may also exert anti-inflammatory effects. Nevertheless, for all these glucose-lowering agents, it is essential to distinguish between anti-inflammatory effects resulting from better glucose control and potential anti-inflammatory effects related to intrinsic actions of the pharmacological class. Finally, it would also be of major clinical interest to define what role the anti-inflammatory effects of these glucose-lowering agents may play in the prevention of macrovascular and microvascular diabetic complications.
