Many people with type 2 diabetes mellitus (T2DM) fail to achieve glycaemic control promptly after diagnosis and do not receive timely treatment intensification. This may be in part due to 'clinical inertia', defined as the failure of healthcare providers to initiate or intensify therapy when indicated. Physician-, patient- and healthcare-system-related factors all contribute to clinical inertia. However, decisions that appear to be clinical inertia may, in fact, be only 'apparent' clinical inertia and may reflect good clinical practice on behalf of the physician for a specific patient. Delay in treatment intensification can happen at all stages of treatment for people with T2DM, including prescription of lifestyle changes after diagnosis, introduction of pharmacological therapy, use of combination therapy where needed and initiation of insulin. Clinical inertia may contribute to people with T2DM living with suboptimal glycaemic control for many years, with dramatic consequences for the patient in terms of quality of life, morbidity and mortality, and for public health because of the huge costs associated with uncontrolled T2DM. Because multiple factors can lead to clinical inertia, potential solutions most likely require a combination of approaches involving fundamental changes in medical care. These could include the adoption of a person-centred model of care to account for the complex considerations influencing treatment decisions by patients and physicians. Better patient education about the progressive nature of T2DM and the risks inherent in long-term poor glycaemic control may also reinforce the need for regular treatment reviews, with intensification when required.

OBJECTIVE This study compared the efficacy and safety of once-weekly dulaglutide, a glucagon-like peptide-1 receptor agonist, with daily insulin glargine, both combined with maximally tolerated doses of metformin and glimepiride in patients with type 2 diabetes. The primary objective was noninferiority of dulaglutide 1.5 mg to glargine in the HbA1c change from baseline at 52 weeks. RESEARCH DESIGN AND METHODS In this 78-week, open-label study, 810 patients were randomized to dulaglutide 1.5 mg, dulaglutide 0.75 mg, or glargine. RESULTS The baseline mean ± SD HbA1c was 8.1 ± 1.0% (65.5 ± 10.8 mmol/mol). The least squares mean ± SE HbA1c change from baseline to the primary end point was −1.08 ± 0.06% (−11.8 ± 0.7 mmol/mol) for dulaglutide 1.5 mg, −0.76 ± 0.06% (−8.3 ± 0.7 mmol/mol) for dulaglutide 0.75 mg, and −0.63 ± 0.06% (−6.9 ± 0.7 mmol/mol) for glargine, with an end point mean ± SD dose of 29 ± 26 units (0.33 ± 0.24 units/kg), and a fasting plasma glucose (mean ± SD) of 118 ± 23 mg/dL from self-monitored plasma glucose. Statistical criteria for superiority were met with dulaglutide 1.5 mg and for noninferiority with dulaglutide 0.75 mg. More patients on dulaglutide 1.5 mg achieved HbA1c targets CONCLUSIONS Once-weekly dulaglutide 1.5 mg, compared with daily insulin glargine without forced titration, demonstrated greater HbA1c reduction and weight loss, with a higher incidence of gastrointestinal adverse events and a lower risk of hypoglycemia.

OBJECTIVE Compare the efficacy and safety of monotherapy with dulaglutide, a once-weekly GLP-1 receptor agonist, to metformin-treated patients with type 2 diabetes. The primary objective compared dulaglutide 1.5 mg and metformin on change from baseline glycosylated hemoglobin A1c (HbA1c) at 26 weeks. RESEARCH DESIGN AND METHODS This 52-week double-blind study randomized patients to subcutaneous dulaglutide 1.5 mg, dulaglutide 0.75 mg, or metformin. Patients (N = 807) had HbA1c ≥6.5% (≥48 mmol/mol) and ≤9.5% (≤80 mmol/mol) with diet and exercise alone or low-dose oral antihyperglycemic medication (OAM) monotherapy; OAMs were discontinued at beginning of lead-in period. RESULTS At 26 weeks, changes from baseline HbA1c (least squares [LS] mean ± SE) were: dulaglutide 1.5 mg, −0.78 ± 0.06% (−8.5 ± 0.70 mmol/mol); dulaglutide 0.75 mg, −0.71 ± 0.06% (−7.8 ± 0.70 mmol/mol); and metformin, −0.56 ± 0.06% (−6.1 ± 0.70 mmol/mol). Dulaglutide 1.5 and 0.75 mg were superior to metformin (LS mean difference): −0.22% (−2.4 mmol/mol) and −0.15% (−1.6 mmol/mol) (one-sided P < 0.025, both comparisons), respectively. Greater percentages reached HbA1c targets CONCLUSIONS Dulaglutide improves glycemic control and is well tolerated as monotherapy in patients with early stage type 2 diabetes.

This Phase 3, randomized, double-blind, parallel-arm, monotherapy study compared the efficacy and safety of 2 doses of dulaglutide (DU), a long-acting GLP-1-receptor agonist, to metformin (MET) in patients with early type 2 diabetes (mean 2.6 years) treated with diet and exercise alone or in combination with 1 oral antidiabetic medication (low dose for ≥ 3 months before screening).

Background: Information is lacking on the potential effect of n3 polyunsaturatedfattyacids(PUFAs)ontheadiposetissueofpatients with type 2 diabetes. Objective: We evaluated whether n3 PUFAs have additional effects on adiposity, insulin sensitivity, adipose tissue function (production of adipokines and inflammatory and atherogenic factors), and gene expression in type 2 diabetes. Design: Twenty-seven women with type 2 diabetes without hypertriglyceridemia were randomly allocated in a double-blind parallel design to 2 mo of 3 g/d of either fish oil (1.8 g n3 PUFAs) or placebo (paraffin oil). Results: Although body weight and energy intake measured by use of a food diary were unchanged, total fat mass (P 0.019) and subcutaneous adipocyte diameter (P 0.0018) were lower in the fish oil group than in the placebo group. Insulin sensitivity was not significantlydifferentbetweenthe2groups(measuredbyhomeostasis model assessment in all patients and by euglycemichyperinsulinemic clamp in a subgroup of 5 patients per group). By contrast, atherogenic risk factors, including plasma triacylglycerol (P 0.03), the ratio of triacylglycerol to HDL cholesterol (atherogenic index, P 0.03), and plasma plasminogen activator inhibitor-1 (P 0.01), were lower in the fish oil group than in the placebo group. In addition, a subset of inflammation-related genes wasreducedinsubcutaneousadiposetissueafterthefishoil,butnot the placebo, treatment. Conclusions: A moderate dose of n3 PUFAs for 2 mo reduced adiposity and atherogenic markers without deterioration of insulin sensitivity in subjects with type 2 diabetes. Some adipose tissue inflammation-related genes were also reduced. These beneficial effects could be linked to morphologic and inflammatory changes in adipose tissue.
