RESUMO
BACKGROUND: Metformin is the regulatory-approved treatment of choice for most youth with type 2 diabetes early in the disease. However, early loss of glycemic control has been observed with metformin monotherapy. Whether liraglutide added to metformin (with or without basal insulin treatment) is safe and effective in youth with type 2 diabetes is unknown. METHODS: Patients who were 10 to less than 17 years of age were randomly assigned, in a 1:1 ratio, to receive subcutaneous liraglutide (up to 1.8 mg per day) or placebo for a 26-week double-blind period, followed by a 26-week open-label extension period. Inclusion criteria were a body-mass index greater than the 85th percentile and a glycated hemoglobin level between 7.0 and 11.0% if the patients were being treated with diet and exercise alone or between 6.5 and 11.0% if they were being treated with metformin (with or without insulin). All the patients received metformin during the trial. The primary end point was the change from baseline in the glycated hemoglobin level after 26 weeks. Secondary end points included the change in fasting plasma glucose level. Safety was assessed throughout the course of the trial. RESULTS: Of 135 patients who underwent randomization, 134 received at least one dose of liraglutide (66 patients) or placebo (68 patients). Demographic characteristics were similar in the two groups (mean age, 14.6 years). At the 26-week analysis of the primary efficacy end point, the mean glycated hemoglobin level had decreased by 0.64 percentage points with liraglutide and increased by 0.42 percentage points with placebo, for an estimated treatment difference of -1.06 percentage points (P<0.001); the difference increased to -1.30 percentage points by 52 weeks. The fasting plasma glucose level had decreased at both time points in the liraglutide group but had increased in the placebo group. The number of patients who reported adverse events was similar in the two groups (56 [84.8%] with liraglutide and 55 [80.9%] with placebo), but the overall rates of adverse events and gastrointestinal adverse events were higher with liraglutide. CONCLUSIONS: In children and adolescents with type 2 diabetes, liraglutide, at a dose of up to 1.8 mg per day (added to metformin, with or without basal insulin), was efficacious in improving glycemic control over 52 weeks. This efficacy came at the cost of an increased frequency of gastrointestinal adverse events. (Funded by Novo Nordisk; Ellipse ClinicalTrials.gov number, NCT01541215.).

AIMS: To assess health-related quality of life (HRQoL) in people with type 2 diabetes (T2D) participating in the LEADER cardiovascular outcomes trial using the five-dimension European Quality of Life questionnaire (EQ-5D). MATERIALS AND METHODS: The EQ-5D was administered every 12 months in a subset of patients from Canada, Denmark, Germany, Ireland, Italy, Netherlands, Spain, Sweden, the United Kingdom and the United States. We compared changes in utility index scores and visual analogue scale (VAS) scores from baseline to 36 months in participants treated with liraglutide and placebo. We also assessed which complications had the greatest impact on quality of life. RESULTS: At 36 months, less deterioration in EQ-5D utility index score was seen in the liraglutide group (-0.058) than in the placebo group (-0.082; estimated treatment difference [ETD] 0.023, 95% confidence interval [CI] 0.004;0.043; P = 0.020). A smaller decrease in EQ-5D VAS score was also demonstrated in the liraglutide group (-3.51) vs. the placebo group (-5.45; ETD 1.94, 95% CI 0.32;3.57; P = 0.019). The benefits of liraglutide treatment compared with placebo were driven primarily by shifts in the domains of mobility and self-care. The most influential events contributing to poorer HRQoL were stroke, heart failure, malignant neoplasm and confirmed hypoglycaemia. CONCLUSIONS: Liraglutide demonstrated a modest but significant benefit in patient-reported health status using the EQ-5D, compared with placebo. This benefit may be of clinical relevance and requires further study.

INTRODUCTION: The LEADER trial was a cardiovascular (CV) outcomes trial in patients with type 2 diabetes at high CV risk that compared liraglutide (n = 4668) with placebo (n = 4672) using a primary composite endpoint of 3-point major adverse CV events. The objective of this post hoc analysis was to investigate glycaemic outcomes across both treatment groups. METHODS: Glycated haemoglobin (HbA1c) was measured at randomisation, month 3, month 6 and every 6 months thereafter. Cox regression was used to analyse time to a composite endpoint of glycaemic deterioration, defined as a specified change in HbA1c or a substantial intensification of insulin or oral antihyperglycaemic drug (OAD). The individual components of the composite were also analysed. RESULTS: Baseline characteristics, including insulin and OAD use, were balanced between treatment groups. HbA1c decreased from baseline in both groups, but the reduction was greater with liraglutide [estimated treatment difference at month 36: - 0.40%; 95% confidence interval (CI) - 0.45, - 0.34] despite the addition of more OADs and higher insulin use in the placebo group. Fewer of the patients treated with liraglutide (n = 3202, 68.6%) experienced glycaemic deterioration compared with those administered the placebo (n = 3988, 85.4%; average hazard ratio: 0.50; 95% CI 0.48, 0.53; p < 0.001). Analysis of the individual components showed similar results (both p < 0.001). CONCLUSIONS: Type 2 diabetes patients at high risk of CV events who were treated with liraglutide achieved greater reductions in HbA1c, had a lower risk of hypoglycaemia and presented less glycaemic deterioration than similar patients who received the placebo. Nonetheless, progressive loss of glycaemic control occurred in both groups. TRIAL REGISTRATION: ClinicalTrials.gov, NCT01179048. FUNDING: Novo Nordisk.

RESUMO
OBJECTIVE: To examine the long-term efficacy and safety of five intra-articular injections with hyaluronan in knee osteoarthritis. METHODS: A multicentre, randomised, placebo-controlled double-blind study of 337 patients fulfilling the American College of Rheumatology (ACR) criteria for knee osteoarthritis (clinical and laboratory) and with a Lequesne algofunctional index score (LFI) of 10 or greater. Patients received a hyaluronan product (sodium hyaluronate; Hyalgan) (n=167) or saline (n=170) intra-articularly weekly for 5 weeks and were followed up to 1 year. Time to recurrence was the primary efficacy parameter. LFI, pain on walking 50 m based on visual analogue scale (VAS pain 50 m), paracetamol consumption, patients' global assessment, Nottingham health profile, joint effusion and number of responders were secondary efficacy parameters. The efficacy parameters were analysed by intention to treat (ITT) and per protocol (PP). All adverse events (AE) were recorded as safety parameters. RESULTS: Time to recurrence showed no significant treatment effect (ITT analysis, p=0.26). Change from baseline in LFI and VAS pain 50 m for the ITT population showed no treatment effect. Paracetamol consumption, patients' global assessment, responder rates and AE displayed no significant difference between treatment groups, analysed by both ITT and PP. Treatment compliance was 95% in the hyaluronan group and 99% in the placebo group. No safety problems were registered. CONCLUSION: In patients fulfilling the ACR criteria for osteoarthritis of the knee with moderate to severe disease activity (LFI > or = 10), five intra-articular injections of hyaluronan did not improve pain, function, paracetamol consumption or other efficacy parameters 3, 6, 9 and 12 months after the treatment.
