Safety and efficacy of once-weekly dulaglutide versus sitagliptin after 2 years in metformin-treated patients with type 2 diabetes (AWARD-5): a randomized, phase III study. Diabetes Obes Metab 2015; 17:849-58. [PMID: 25912221 PMCID: PMC5008205 DOI: 10.1111/dom.12479] [Citation(s) in RCA: 95] [Impact Index Per Article: 10.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/19/2015] [Revised: 04/10/2015] [Accepted: 04/17/2015] [Indexed: 11/30/2022]
Abstract
AIMS To compare the once-weekly glucagon-like peptide-1 (GLP-1) receptor dulaglutide with the dipeptidyl peptidase-4 (DPP-4) inhibitor sitagliptin after 104 weeks of treatment. METHODS This AWARD-5 study was a multicentre, double-blind trial that randomized participants to dulaglutide (1.5 or 0.75 mg) or sitagliptin 100 mg for 104 weeks or placebo (reported separately) for 26 weeks. Change in glycated haemoglobin (HbA1c) concentration from baseline was the primary efficacy measure. A total of 1098 participants with HbA1c concentrations ≥7.0% (≥53.0 mmol/mol) and ≤9.5% (≤80.3 mmol/mol) were randomized, and 657 (59.8%) completed the study. We report results for dulaglutide and sitagliptin at the final endpoint. RESULTS Changes in HbA1c at 104 weeks were (least squares mean ± standard error) -0.99 ± 0.06% (-10.82 ± 0.66 mmol/mol), -0.71 ± 0.07% (-7.76 ± 0.77 mmol/mol) and -0.32 ± 0.06% (-3.50 ± 0.66 mmol/mol) for dulaglutide 1.5 mg, dulaglutide 0.75 mg and sitagliptin, respectively (p < 0.001, both dulaglutide doses vs sitagliptin). Weight loss was greater with dulaglutide 1.5 mg (p < 0.001) and similar with 0.75 mg versus sitagliptin (2.88 ± 0.25, 2.39 ± 0.26 and 1.75 ± 0.25 kg, respectively). Gastrointestinal adverse events were more common with dulaglutide 1.5 and 0.75 mg versus sitagliptin (nausea 17 and 15% vs 7%, diarrhoea 16 and 12% vs 6%, vomiting 14 and 8% vs 4% respectively). Pancreatic, thyroid, cardiovascular and hypersensitivity safety were similar across groups. CONCLUSIONS Dulaglutide doses provided superior glycaemic control and dulaglutide 1.5 mg resulted in greater weight reduction versus sitagliptin at 104 weeks, with acceptable safety.

Improved glucose control with reduced hypoglycaemic risk when linagliptin is added to basal insulin in elderly patients with type 2 diabetes. Diabetes Obes Metab 2015; 17:868-77. [PMID: 25974030 DOI: 10.1111/dom.12490] [Citation(s) in RCA: 18] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/11/2015] [Revised: 04/14/2015] [Accepted: 05/07/2015] [Indexed: 01/21/2023]
Abstract
AIM To assess the efficacy, hypoglycaemia risk and other safety markers of linagliptin as an additional therapy in older patients (aged ≥70 years) inadequately controlled with basal insulin. METHODS A prespecified safety analysis from the linagliptin trials programme was carried out to explore the hypoglycaemia risk when linagliptin was added to background basal insulin therapy in elderly patients (≥70 years). To do this, two eligible, randomized, placebo-controlled, clinical trials (NCT00954447 and NCT01084005) of 24 and ≥52 weeks, respectively, were analysed. RESULTS A total of 247 elderly individuals [mean ± standard deviation (s.d.) age 74 ± 4 years, glycated haemoglobin (HbA1c) 8.2 ± 0.8%] on basal insulin (mean ± s.d. baseline dose 36 ± 25 IU/day) were identified. Alongside placebo-adjusted change in HbA1c with linagliptin of -0.77% [95% confidence interval (CI) -0.95 to 0.59; p < 0.0001] after 24 weeks, the hazard ratios (HRs) of both overall and confirmed hypoglycaemia [blood glucose ≤3.9 mmol/l (70 mg/dl)], were significantly lower with linagliptin than with placebo: HR 0.61 (95% CI 0.39-0.97) versus 0.59 (95% CI 0.37-0.94), respectively (both p < 0.05). Moreover, significantly less confirmed hypoglycaemia was present in linagliptin-treated patients with renal impairment [HR 0.45 (95% CI 0.27-0.76)], moderate hyperglycaemia [HbA1c 7.5 to <9.0%; HR 0.51 (95% CI 0.27-0.99)], lower fasting plasma glucose levels [<152 mg/dl; HR 0.49 (95% CI 0.28-0.86)] and those treated with higher insulin doses [insulin ≥35.6 IU/day; HR 0.46 (95% CI 0.23-0.91); p < 0.05 for all]. Severe hypoglycaemia was rare and the incidence was lower with linagliptin (0.8%) versus placebo (2.5%): HR 0.21 (95% CI 0.02-2.30). CONCLUSIONS Despite improvements in hyperglycaemia and no relevant on-trial insulin dose reductions, adding linagliptin to basal insulin appears to decrease hypoglycaemia risk. The biological basis of this phenomenon warrants further research but may involve counter-regulatory effects of incretin hormones.

Abstract
Obesity is often considered to have a protective effect against osteoporosis. On the other hand, several recent studies suggest that adipose tissue may have detrimental effects on bone quality. We therefore aimed to investigate the associations between body mass index (BMI), waist circumference (WC), visceral adipose tissue (VAT) or abdominal subcutaneous adipose tissue (SAT), and bone stiffness. The study involved 2685 German adults aged 20-79 years, who participated in either the second follow-up of the population-based Study of Health in Pomerania (SHIP-2) or the baseline examination of the SHIP-Trend cohort. VAT and abdominal SAT were quantified by magnetic resonance imaging. Bone stiffness was assessed by quantitative ultrasound (QUS) at the heel (Achilles InSight, GE Healthcare). The individual risk for osteoporotic fractures was determined based on the QUS-derived stiffness index and classified in low, medium, and high risk. Linear regression models, adjusted for sex, age, physical activity, smoking status, risky alcohol consumption, diabetes, and height (in models with VAT or abdominal SAT as exposure), revealed positive associations between BMI, WC, VAT or abdominal SAT, and the QUS variables broadband-ultrasound attenuation or stiffness index. Moreover, BMI was positively associated with speed of sound. Our study shows that all anthropometric measures including BMI and, WC as well as abdominal fat volume are positively associated with bone stiffness in the general population. As potential predictors of bone stiffness, VAT and abdominal SAT are not superior to easily available measures like BMI or WC.

Abstract
BACKGROUND Body mass index (BMI) and serum 25-hydroxy vitamin D3 (25OHD) concentrations are inversely related. As BMI contains only limited information regarding body fat distribution, we aimed to analyze the cross-sectional associations of abdominal visceral or subcutaneous adipose tissue, next to common adiposity measures, with the 25OHD concentration. METHODS Data were obtained from three cohorts of two large epidemiological studies in the northeast of Germany (Study of Health in Pomerania, SHIP-1 and SHIP-Trend), and in Denmark (Health2006). The study populations included adult men and women from the general population (N = 3072 SHIP-1, N = 803 SHIP-Trend, N = 3195 Health2006). Visceral and subcutaneous adipose tissue were quantified by magnetic resonance imagining (SHIP-Trend) or ultrasound (Health2006). Common adiposity measures, including BMI, waist circumference, waist-to-hip ratio, waist-to-height ratio, body surface area, and body fat percentage were determined by standardized methods in SHIP-1 and Health2006. RESULTS The average study participant was overweight (median BMI 27.4, 26.6, and 25.2 kg/m(2) in SHIP-1, SHIP-Trend, and Health2006, respectively). Visceral and subcutaneous adipose tissue as well as the common adiposity measures were inversely associated with serum 25OHD concentrations in linear regression models adjusted for age, sex, alcohol consumption, physical activity, smoking status, and month of blood sampling. CONCLUSIONS Next to common adiposity measures, also abdominal visceral or subcutaneous adipose tissue are inversely associated with serum 25OHD concentrations in the general adult population.

Abstract
AIMS To assess the long-term efficacy and tolerability of dapagliflozin versus glipizide as add-on to metformin in patients with inadequately controlled type 2 diabetes. METHODS The present study was an extension of an earlier randomized, double-blind, phase III study of dapagliflozin (n = 406) vs glipizide (n = 408) to 208 weeks (4 years). Patients continued to receive their assigned medication. No statistical treatment-group comparisons were calculated. RESULTS At 208 weeks, dapagliflozin compared with glipizide produced sustained reductions in glycated haemoglogin (HbA1c): -0.30% [95% confidence interval (CI), -0.51 to -0.09], in total body weight: -4.38 kg (95% CI -5.31 to -3.46) and in systolic blood pressure (SBP): -3.67 mmHg (95% CI -5.92 to -1.41). The HbA1c coefficient of failure was significantly lower for dapagliflozin than for glipizide: 0.19 (95% CI 0.12-0.25) versus 0.61 (95% CI 0.49-0.72, difference -0.42; p = 0.0001). Dapagliflozin was not associated with glomerular function deterioration, while this occurred more frequently in patients in the glipizide group. Fewer patients reported hypoglycaemia in the dapagliflozin compared with the glipizide group (5.4 vs 51.5%). Genital and urinary tract infections were more common with dapagliflozin than with glipizide, but their incidence decreased with time and all events responded well to antimicrobial treatment. CONCLUSIONS In patients completing 4 years of treatment, dapagliflozin was well tolerated and associated with sustained glycaemic efficacy and greater reductions in body weight and SBP versus glipizide.

Abstract
AIMS To report preliminary data on baseline serum calcitonin concentrations and associated clinical characteristics in a global population with type 2 diabetes before liraglutide or placebo randomization. METHODS The ongoing LEADER trial has enrolled 9340 people with type 2 diabetes and at high risk of cardiovascular disease at 410 centres worldwide. People with baseline serum calcitonin ≤ 50 ng/l were randomized to liraglutide once daily or placebo and will be followed for up to 5 years. Serum calcitonin was measured at baseline and will be measured annually thereafter. An independent committee of thyroid experts will oversee calcitonin monitoring throughout the trial and will review all calcitonin concentrations ≥ 20 ng/l. RESULTS The mean age of participants was 64.3 ± 7.2 years, 64.3% were men, and mean the body mass index was 32.5 ± 6.3 kg/m(2). The median (interquartile range) baseline serum calcitonin values were 3.9 (1.0 to >7.6) ng/l in men and 1.0 (1.0 to >1) ng/l in women. Serum calcitonin was >10 ng/l in 14.6% of men and in 0.96% of women. In sex-specific multivariable linear analysis of covariance models, a reduced glomerular filtration rate (GFR) was associated with higher serum calcitonin concentrations that were statistically significant. A 20 ml/min/1.73 m(2) decrease in estimated GFR (eGFR) was associated with a 14% increase in serum calcitonin in women and an 11% increase in men. CONCLUSIONS In the LEADER population, the prevalence of elevated serum calcitonin concentrations at baseline was high, and there was an inverse association between eGFR and serum calcitonin concentrations.

Abstract
BACKGROUND AND AIMS Accumulating evidence demonstrates an important interaction between bone and energy metabolism. We aimed to study the associations of three bone turnover markers (BTM: osteocalcin, beta-crosslaps, procollagen type 1 N-terminal propeptide) as well as of 25-hydroxyvitamin D and parathyroid hormone with metabolic syndrome (MetS) or type 2 diabetes mellitus (T2DM) in a large population-based cohort. METHODS AND RESULTS This cross-sectional study comprised 2671 adult men and women participating in the first follow-up of the population-based Study of Health in Pomerania (SHIP-1). Multivariable logistic regression analyses were performed to assess sex-specific associations between the BTMs, 25-hydroxyvitamin D or parathyroid hormone and metabolic disease. All models were adjusted for age, body mass index, smoking status, physical activity, estimated glomerular filtration rate and month of blood sampling. The models for women were further adjusted for menopausal status. Higher BTM or 25-hydroxyvitamin D concentrations were associated with significantly lower odds for metabolic disease, while there was no association between parathyroid hormone and MetS or T2DM. CONCLUSION Our results contribute to the accumulating evidence of a cross-sectional association between high BTM or 25-hydroxyvitamin D concentrations and a lower prevalence of MetS or T2DM. Further research is necessary to evaluate the mechanisms underlying these results.

Abstract
AIMS To assess the long-term glycaemic durability, safety and tolerability of dapagliflozin versus glipizide as add-on therapies in patients with type 2 diabetes inadequately controlled by metformin alone. METHODS This was a 52-week, randomised, double-blind study of dapagliflozin (n = 406) versus glipizide (n = 408), uptitrated over 18 weeks according to tolerability and glycaemic response to a maximum of 10 and 20 mg/day, respectively, as add-on therapies to metformin (≥ 1500 mg/day) with a 156-week double-blind extension period. Data over 104 weeks are reported here. RESULTS In total, 53.1% of patients completed 104 weeks of treatment. After the greater initial decrease (0-18 weeks) in glycated haemoglobin (HbA1c) with glipizide, the 18-104-week HbA1c coefficient of failure (CoF) was lower with dapagliflozin (0.13%/year) than with glipizide (0.59%/year), resulting in significant dapagliflozin versus glipizide differences of -0.46%/year (95% CI -0.60,-0.33; p = 0.0001) for CoF and -0.18%(-2.0 mmol/mol) [95% CI -0.33(-3.6),-0.03(-0.3); p = 0.021] for 104-week HbA1c. Dapagliflozin produced sustained reductions in weight and systolic blood pressure, whereas glipizide increased weight and systolic blood pressure, giving 104-week dapagliflozin versus glipizide differences of -5.1 kg (95% CI: -5.7,-4.4) and -3.9 mmHg (95% CI: -6.1,-1.7), respectively. Over 104 weeks, the hypoglycaemia rate was 10-fold lower with dapagliflozin than with glipizide (4.2 vs. 45.8%), whereas patient proportions with events suggestive of genital infection and of urinary tract infection (UTI) were greater with dapagliflozin (14.8 and 13.5%, respectively) than with glipizide (2.9 and 9.1%, respectively). CONCLUSIONS Over 2 years, compared with glipizide, dapagliflozin demonstrated greater glycaemic durability, sustained reductions in weight and systolic blood pressure and a low hypoglycaemia rate; however, genital infections and UTIs occurred more frequently.

Abstract
AIMS Our aim was to assess the number of medications prescribed to people with Type 1 or Type 2 diabetes mellitus and to compare these to recommendations by guidelines. PATIENTS AND METHODS Data from 155 and 154 people with Type 1 and Type 2 diabetes, respectively, were analysed. Prescribed medications (glucose-lowering drugs, blood pressure medications, drugs to treat cardiovascular risk or diseases, etc.) were counted as compounds per day, tablets per day, injections per day, or other modes of administration. RESULTS People with Type 2 diabetes were prescribed 8.4 ± 3.0 different drug compounds per day (maximum, 16), 8.6 ± 3.9 tablets per day (maximum, 22), 2.6 ± 1.6 injections per day (maximum, 7), in total 11.6 ± 4.5 doses of any medication per day (maximum, 27). The numbers for people with Type 1 diabetes were 5.5 ± 3.4 compounds per day (maximum, 15), 4.5 ± 4.3 tablets per day (maximum, 18), 3.9 ± 2.2 injections per day (maximum, 8), in total 8.5 ± 5.1 doses of any medication per day (maximum, 22). Over 97% of the prescriptions corresponded to recommendations by guidelines. CONCLUSIONS The number of prescribed drugs is high in people with diabetes mellitus, and higher for those with Type 2 than with Type 1 diabetes. The compatibility of prescriptions with guideline recommendations suggests that even this high number of prescriptions will provide a clinical benefit. The current analysis could provide a basis for a realistic judgement of the burden imposed by polypharmacy in people with diabetes mellitus.

Abstract
In vitro and in vivo models revealed that the somatotropic system exerts central effects on the central nervous system. Disturbances to this system such as in the case of growth hormone deficiency or growth hormone excess, are associated with a wide range of psychiatric disorders. Nonetheless, there is no epidemiological data available regarding the influence of growth hormone and its mediator, insulin-like growth factor I (IGF-I), on depressive disorders. The objective of this study was to investigate whether endogenous IGF-I levels may predict depression in humans. We included 4079 adult subjects from the Study of Health in Pomerania (SHIP), a population-based study with a 5-year follow-up period. The main predictor was the baseline IGF-I value categorized in three levels as <10th percentile, between the 10th and the 90th percentile (the reference group) and >90th percentile. The outcome measure was the incidence of depressive disorders according to the Composite International Diagnostic-Screener (CID-S). After adjustment for potential confounding variables, females with IGF-I levels below the 10th percentile had a higher incidence of depressive disorders during follow-up (OR 2.70 95% CI 1.38-5.28, p=0.004) compared to females within the reference group (10th-90th percentile). Among males, those with IGF-I levels above the 90th percentile had a higher risk of depressive disorder (OR 3.26 95% CI 1.52-6.98, p=0.002) than those within the 10th-90th percentile. In conclusion we can demonstrate that low IGF-I levels in females and high IGF-I levels in males predict the development of depressive disorders in this general adult population sample.

Abstract
Vitamin D deficiency and oral diseases (periodontitis, caries, and tooth loss) are highly prevalent in Germany. Previous studies suggested that vitamin D might be a modifiable and protective factor for periodontitis, caries, and tooth loss. However, prospective studies investigating such associations are limited. We explored the association between the concentration of serum 25-hydroxy vitamin D (25OHD) and incidence of tooth loss, progression of clinical attachment loss (CAL) ≥ 3 mm, and progression of restorative and caries status in a population-based longitudinal study. We analyzed data from 1,904 participants from the Study of Health in Pomerania with a five-year follow-up. Generalized estimating equation models were applied to evaluate tooth-specific associations between serum 25OHD and incidence of tooth loss, progression of CAL ≥ 3 mm, and progression of restorative and caries status. Age, sex, education, smoking status, alcohol drinking, waist circumference, dental visit frequency, reasons of dental visit, vitamin D or calcium supplements, and season of blood draw were considered as confounders. Serum 25OHD was inversely associated with incidence of tooth loss. A significant dose-response relationship (p = .0022) was observed across the quintiles of serum 25OHD. After adjusting for multiple confounders, each 10-µg/L increase of serum 25OHD was associated with a 13% decreased risk of tooth loss (risk ratio: 0.87; 95% confidence interval: 0.79, 0.96). The association was attenuated for changes of CAL ≥ 3 mm when adjusting for multiple confounders. No significant association was found between serum 25OHD and caries progression. Vitamin D might be a protective factor for tooth loss. The effect might partially be mediated by its effect on periodontitis.
