sitagliptin-phosphate and dapagliflozin

This article reviews evidence supporting sodium glucose cotransporter 2 (SGLT2) inhibitor and dipeptidyl peptidase-4 (DPP-4) inhibitor combination therapy for management of type 2 diabetes mellitus (T2DM).. We conducted a nonsystematic review of the literature focusing on single-pill or fixed-dose combinations of SGLT2 inhibitors and DPP-4 inhibitors available in the United States.. SGLT2 inhibitors and DPP-4 inhibitors have complementary mechanisms of action that address several of the underlying pathophysiologic abnormalities present in T2DM without overlapping toxicities. The combination of these 2 agents has several advantages including a low risk of hypoglycemia, the potential for weight loss, the ability to coformulate into a pill with once-daily administration, and the possibility to use with other classes of glucose-lowering agents. Cardiovascular outcomes trials reported to date support the safety of the DPP-4 class and suggest possible cardioprotective effects for SGLT2 inhibitors - at least based on the first reported study that used empagliflozin. Recent clinical evidence shows that SGLT2 inhibitor/DPP-4 inhibitor therapy is an effective combination for T2DM treatment, providing glycated hemoglobin (HbA1c) reductions of 1.1 to 1.5%, and weight reductions of approximately 2 kg when added to metformin, which is its primary place in therapy.. The combination of an SGLT2 inhibitor/DPP-4 inhibitor is a safe and effective treatment choice for patients with T2DM who are unable to obtain adequate glycemic control with metformin therapy, cannot use metformin, or have a higher baseline HbA1c..

Type 2 diabetes (T2D) generally requires a combination of several pharmacological approaches to control hyperglycaemia. Combining a sodium-glucose cotransporter type 2 inhibitor (SGLT2I, also known as gliflozin) and a dipeptidyl peptidase-4 inhibitor (DPP-4I, also known as gliptin) appears to be an attractive strategy because of complementary modes of action. This narrative review analyzes the pharmacokinetics and clinical efficacy of different combined therapies with an SGLT2I (canagliflozin, dapagliflozin, empagliflozin, ertugliflozin, ipragliflozin, luseogliflozin, tofogliflozin) and DPP-4I (linagliptin, saxagliptin, sitagliptin, teneligliptin). Drug-drug pharmacokinetic interaction studies do not show any significant changes in peak concentrations (C

Hypoglycemia is the most common side effects for most glucose-lowering therapies. It constitutes a serious risk that faces diabetic patients who fast during Ramadan (the 9th month in the Islamic calendar). New glucose-lowering classes like dipeptidyl peptidase-4 (DPP-4) inhibitors, glucagon-like peptide 1 receptor agonist (GLP-1 RA), and sodium-glucose cotransporter-2 (SGLT-2) inhibitors are efficacious in controlling blood glucose level with less tendency to induce hypoglycemia and thus may constitute a good choice for diabetic patients during Ramadan. This study reviews the safety and efficacy of newer glucose-lowering therapies during Ramadan. This study was accomplished through a careful literature search about studies that assess the benefit and side effects of these new glucose-lowering therapies during Ramadan during September 2015. Vildagliptin, sitagliptin, liraglutide, exenatide, and dapagliflozin were the only studied glucose-lowering therapies. All of the studied newer glucose-lowering therapies except dapagliflozin were associated with reduced risk to induce hypoglycemia. Gastrointestinal upset was common with the usage of liraglutide while increased thirst sensation was common with dapagliflozin. In conclusion DPP-4 inhibitors such as vildagliptin and sitagliptin may form a suitable glucose-lowering therapy option for Ramadan fasting patients.

To compare the effects of baseline background characteristics in patients treated with dapagliflozin and sitagliptin in the DIVERSITY-CVR study and to analyse the time in range (TIR), a metric for glycaemic control.. This prospective, randomized, multicentre study included 340 Japanese patients with early-stage type 2 diabetes. To examine the effects of dapagliflozin and sitagliptin on glycaemic variability, we re-examined the primary endpoint (glycated haemoglobin [HbA1c] < 7.0%, body weight loss ≥ 3.0%, and avoidance of hypoglycaemia) achievement rate in participants stratified by baseline background characteristics.. Sitagliptin was significantly superior in achieving HbA1c level <7.0% in the lower body mass index (BMI) group (71.1% vs. 43.6%; P < 0.05), with no significant differences in other subgroups. In the lower BMI group, the rate of achievement of TIR > 70% after 24-week treatment was significantly higher with sitagliptin than with dapagliflozin (91.9% vs. 69.4%; P < 0.05). In contrast, dapagliflozin was superior to sitagliptin in achieving TIR > 70% in the higher BMI group (85.7% vs. 52.9%; P < 0.01).. In Japanese patients with early-stage type 2 diabetes, sitagliptin was associated with improved TIR in patients with a lower BMI. Dapagliflozin was effective in patients with a higher BMI.

This study compared efficacy and safety of triple drug fixed-dose combination (FDC) of dapagliflozin (DAPA) + sitagliptin (SITA) + metformin (MET) extended release (ER) with SITA + MET sustained release (SR) and DAPA + MET ER in patients with type 2 diabetes poorly controlled with metformin.. This phase 3, randomized, open-label, active-controlled study included adult patients with glycated hemoglobin (HbA1c) ≥ 8% (64 mmol/mol) and ≤ 11% (97 mmol/mol), randomized in 1:1:1 ratio to receive either FDC of DAPA + SITA + MET ER (10 mg + 100 mg + 1000 mg) tablets once daily (n = 137) or co-administration of SITA + MET SR (100 mg + 1000 mg) tablets once daily (n = 139) or FDC of DAPA + MET ER (10 mg + 1000 mg) tablets once daily (n = 139). Primary endpoint was mean change in HbA1c from baseline to week 16.. Mean baseline HbA1c was approximately 9% (75 mmol/mol) in each treatment group. At week 16, adjusted mean reduction in HbA1c from baseline was significantly greater with DAPA + SITA + MET ER (- 1.73% [- 19.0 mmol/mol]) compared to SITA + MET SR (- 1.28% [- 14.1 mmol/mol]; difference of - 0.46% [- 5.1 mmol/mol], p < 0.001) and DAPA + MET ER (- 1.33% [- 14.6 mmol/mol]; difference - 0.4% [4.4 mmol/mol], p < 0.001). Similarly, at week 12, reduction in HbA1c from baseline was significantly greater with DAPA + SITA + MET ER compared to SITA + MET SR (p = 0.0006) and DAPA + MET ER (p = 0.0276). At week 16, DAPA + SITA + MET ER showed significant reduction in postprandial blood glucose compared to DAPA + MET ER (p = 0.0394) and significant reduction in fasting blood glucose with DAPA + SITA + MET ER compared to SITA + MET SR (p = 0.0226). The proportion of patients achieving HbA1c < 7.0% (53 mmol/mol) at week 16 was significantly higher with DAPA + SITA + MET ER (38.5%) versus SITA + MET SR (12.8%) (p < 0.001) and DAPA + MET ER (21.3%) (p = 0.0023). All study medications were well tolerated.. Triple FDC of DAPA + SITA + MET ER tablets once daily was significantly better in achieving glycemic control versus dual combination once daily in patients with type 2 diabetes poorly controlled with metformin without any significant safety concerns.. CTRI/2021/11/038176, registered on 22 November 2021.. Type 2 diabetes is a progressive disease in which the risks of microvascular and macrovascular complications and mortality are strongly associated with hyperglycemia. Achieving glycemic control remains the main goal of treatment to prevent these complications. Estimates in 2019 showed that 77 million individuals had diabetes in India, which is expected to rise over 134 million by 2045. Considering the progressive nature of the disease, many guidelines recommend use of dual or triple drug therapy based on glycated hemoglobin (HbA1c) level. Use of fixed-dose combination (FDC) helps to improve therapy compliance and can provide optimum therapeutic benefits. Mechanisms of action of dipeptidyl peptidase 4 (DPP4) and sodium–glucose cotransporter 2 (SGLT2) inhibitors are complementary to that of metformin with low risk of hypoglycemia. Studies have shown beneficial effects of adding both DPP4 inhibitors and SGLT2 inhibitors after metformin monotherapy. This phase 3 study was designed to assess efficacy and safety of triple FDC of dapagliflozin + sitagliptin + metformin extended release in comparison with combipack of sitagliptin + metformin sustained release and FDC of dapagliflozin + metformin ER in patients with type 2 diabetes inadequately controlled with metformin monotherapy. The study demonstrated superiority of triple FDC of dapagliflozin + sitagliptin + metformin ER over dual combinations in terms of reduction in HbA1c and percentage of patients achieving target HbA1c at the end of week 16. The current study provides evidence for considering triple FDC of dapagliflozin + sitagliptin + metformin ER as an alternative option with minimal risk of hypoglycemia and weight gain, while considering oral triple-combination therapy for patients to achieve their glycemic target.

Insulin-treated patients with long duration of type 2 diabetes mellitus (T2DM) are at increased risk of ketoacidosis related to sodium-glucose co-transporter 2 inhibitor (SGLT2i). The extent of circulating ketone elevation in these patients remains unknown. We conducted this study to compare the serum ketone response between dapagliflozin, an SGLT2i, and sitagliptin, a dipeptidyl peptidase-4 inhibitor, among insulin-treated T2DM patients.. This was a randomized, open-label, active comparator-controlled study involving 60 insulin-treated T2DM patients. Participants were randomized 1:1 for 24-week of dapagliflozin 10 mg daily or sitagliptin 100 mg daily. Serum β-hydroxybutyrate (BHB) levels were measured at baseline, 12 and 24 weeks after intervention. Comprehensive cardiometabolic assessments were performed with measurements of high-density lipoprotein cholesterol (HDL-C) cholesterol efflux capacity (CEC), vibration-controlled transient elastography and echocardiography.. Among these 60 insulin-treated participants (mean age 58.8 years, diabetes duration 18.2 years, glycosylated hemoglobin 8.87%), as compared with sitagliptin, serum BHB levels increased significantly after 24 weeks of dapagliflozin (P=0.045), with a median of 27% increase from baseline. Change in serum BHB levels correlated significantly with change in free fatty acid levels. Despite similar glucose lowering, dapagliflozin led to significant improvements in body weight (P=0.006), waist circumference (P=0.028), HDL-C (P=0.041), CEC (P=0.045), controlled attenuation parameter (P=0.007), and liver stiffness (P=0.022). Average E/e', an echocardiographic index of left ventricular diastolic dysfunction, was also significantly lower at 24 weeks in participants treated with dapagliflozin (P=0.037).. Among insulin-treated T2DM patients with long diabetes duration, compared to sitagliptin, dapagliflozin modestly increased ketone levels and was associated with cardiometabolic benefits.

Few prospective studies have compared the cardiovascular benefits of sodium-glucose cotransporter-2 (SGLT2) inhibitors and dipeptidyl peptidase 4 (DPP-4) inhibitors. We aimed to clarify the efficacy of dapagliflozin versus sitagliptin for modulating cardiometabolic risk factors including high glycated hemoglobin (HbA1c) levels, hypoglycemia, and body weight.. This prospective, randomized, open-label, blinded-endpoint, parallel-group trial enrolled 340 Japanese patients with early-stage type 2 diabetes receiving metformin alone or no glucose-lowering agents, who were randomized to receive dapagliflozin or sitagliptin for 24 weeks. The primary endpoint was the proportion of patients who achieved the composite endpoint of HbA1c level maintenance < 7.0% (53 mmol/mol), avoidance of hypoglycemia (maintenance of sensor glucose ≥ 3.0 mmol/L or ≥ 54 mg/dL), and ≥ 3.0% body weight loss from baseline. Secondary endpoints included components of the primary endpoint, other metabolic indices, and glucose variability indices measured using flash glucose monitoring.. Compared to sitagliptin, dapagliflozin was significantly more effective at improving cardiometabolic risk factors, suggesting that SGLT2 inhibitors might be more suitable than DPP-4 inhibitors for preventing cardiovascular events in patients with early-stage but inadequately controlled type 2 diabetes.

Sodium-dependent glucose transporter (SGLT) 2 is specifically expressed in the kidney, while SGLT1 is present in the kidneys and small intestine. SGLT2 inhibitors are a class of oral antidiabetic drugs that lower elevated plasma glucose levels by promoting the urinary excretion of excess glucose through the inhibition of renal glucose reuptake. The inhibition selectivity for SGLT2 over SGLT1 (SGLT2/1 selectivity) of marketed SGLT2 inhibitors is diverse, while SGLT2/1 selectivity of canagliflozin is relatively low. Although canagliflozin suppresses postprandial glucose levels, the degree of contribution for SGLT1 inhibition to this effect remains unproven. To analyze the effect of SGLT2 inhibitors on postprandial glucose level, we constructed a novel quantitative systems pharmacology (QSP) model, called human systemic glucose dynamics (HSGD) model, integrating intestinal absorption, metabolism, and renal reabsorption of glucose. This HSGD model reproduced the postprandial plasma glucose concentration-time profiles during a meal tolerance test under different clinical trial conditions. Simulations after canagliflozin administration showed a dose-dependent delay of time (T

To compare the efficacy and safety of an intensification strategy of early triple combination therapy with dapagliflozin (DAPA) plus saxagliptin (SAXA) to a dual therapy strategy with sitagliptin (SITA) in patients with type 2 diabetes who are inadequately controlled with metformin (MET) monotherapy.. This multinational, active-controlled, parallel-group phase 3b trial randomized 461 patients, at least 18 years of age, with glycated haemoglobin (HbA1c) of 8%-10.5% (64-91 mmol/mol), to either DAPA plus SAXA or SITA, added to MET, for a 26-week double-blind treatment period and an extension of a 26-week blinded treatment period.. Mean (± SD) baseline HbA1c was 8.8% ± 0.9% (73.0 ± 9.3 mmol/mol). DAPA plus SAXA (n = 232) provided a greater reduction from baseline in HbA1c at Weeks 26 and 52 compared with SITA (n = 229) (adjusted mean ± SE change, Week 26: -1.41 ± 0.07% vs -1.07 ± 0.07% [-15.4 ± 0.8 mmol/mol vs 11.7 ± 0.8 mmol/mol]; P = 0.0008; Week 52: -1.29 ± 0.08% vs -0.81 ± 0.09% [14.1 ± 0.9 mmol/mol vs 8.9 ± 1.0 mmol/mol]). The between-group difference in adjusted mean (95% CI) change from baseline in HbA1c increased from -0.34 (-0.54, -0.14) at Week 26 to -0.48 (-0.71, -0.25) at Week 52. DAPA plus SAXA was generally well tolerated and the incidence of adverse events was similar in both treatment arms.. Early intensification to triple therapy with DAPA plus SAXA results in better, more durable glycaemic control than addition of SITA only (dual therapy) in patients with high HbA1c levels who are uncontrolled with MET monotherapy.

Recent studies reported that sodium glucose cotransporter 2 (SGLT2) inhibitors reduced the cardiovascular morbidity and mortality in patients with type 2 diabetes mellitus (T2DM) compared to placebo in contrast to no reduction with dipeptidyl peptidase 4 (DPP4) inhibitors. However, there are no comparative studies on the effects of SGLT2 inhibitors and DPP4 inhibitors on HbA1c, body weight and hypoglycemia as risk factors of cardiovascular diseases. The aim of the present ongoing study is to compare the effects of dapagliflozin, a SGLT2 inhibitor, with those of sitagliptin, a DPP4 inhibitor, on cardiovascular risk factors in T2DM patients with inadequate glycemic control.. The study of dapagliflozin versus sitagliptin treatment efficacy on prevention of cardiovascular risk factors in T2DM patients (DIVERSITY-CVR study) is a prospective, randomized, open-label, blinded-endpoint, parallel-group, comparative study. A total of 340 T2DM patients treated with metformin alone or with no glucose-lowering agents (hemoglobin A1c ≥ 7.0 and < 10.0%) will be randomized into the dapagliflozin group (5-10 mg/day, n = 170) and the sitagliptin group (50-100 mg/day, n = 170), and treated for 24 weeks. The primary endpoint is the rate of achieving a composite endpoint of the following three items at 24th week; (1) HbA1c < 7.0%; (2) body weight loss of ≥ 3.0% from baseline; (3) avoidance of hypoglycemia. Hypoglycemia will be monitored using the flash glucose monitoring system. The secondary outcomes include each component of the primary endpoint, plus indices of lipid metabolism, and evaluations related to safety.. There is lack of solid information on differences in the therapeutic effects of SGLT2 inhibitors and DPP4 inhibitors on multiple risk factors for cardiovascular diseases. It is anticipated that the results of the DIVERSITY-CVR study provides useful clinical data on the management of patients with T2DM, including reducing the risk of CVD. The results of this study will become available in 2019. Trial registration University Hospital Medical Information Network Clinical Trial Registry (UMIN000028014). Registered 30 June 2017.

To compare the efficacy and safety of the dipeptidyl peptidase-4 inhibitor sitagliptin with the sodium-glucose transporter-2 inhibitor dapagliflozin in patients with type 2 diabetes and mild renal insufficiency.. In patients with type 2 diabetes, mild renal insufficiency and inadequate glycaemic control on metformin ± sulfonylurea, sitagliptin treatment resulted in greater improvement in glycaemic control compared with dapagliflozin and was generally well tolerated.

The sodium-glucose co-transporter-2 (SGLT-2) inhibitors have been reported to increase both low-density lipoprotein (LDL) and high-density lipoprotein (HDL)-cholesterol (C). This study aimed to determine how SGLT-2 inhibitors affect LDL and HDL-C subspecies.. This single center, open-label, randomized, prospective study included 80 patients with type 2 diabetes taking prescribed oral hypoglycemic agents. Patients were allocated to receive dapagliflozin (n = 40) or sitagliptin (n = 40) as add-on treatment. Fasting blood samples were collected before and 12 weeks after this intervention. Small dense (sd) LDL-C, large buoyant (lb) LDL-C, HDL2-C, and HDL3-C levels were determined using our established homogeneous assays. Statistical comparison of blood parameters before and after treatment was performed using the paired t test.. Dapagliflozin and sitagliptin comparably decreased HbA1c (0.75 and 0.63%, respectively). Dapagliflozin significantly decreased body weight, systolic blood pressure, plasma triglycerides and liver transaminases, and increased adiponectin; sitagliptin did not alter these measurements. LDL-C and apolipoprotein (apo) B were not significantly changed by dapagliflozin, whereas HDL-C and apo AI were increased. Dapagliflozin did not alter concentrations of LDL-C, but sd LDL-C decreased by 20% and lb LDL-C increased by 18%. Marked elevation in lb LDL-C (53%) was observed in individuals (n = 20) whose LDL-C was elevated by dapagliflozin. However, sd LDL-C remained suppressed (20%). Dapagliflozin increased HDL2-C by 18% without affecting HDL3-C. Sitagliptin did not alter plasma lipids or lipoprotein subspecies.. A SGLT-2 inhibitor, dapagliflozin suppresses potent atherogenic sd LDL-C and increased HDL2-C, a favorable cardiometabolic marker. Although LDL-C levels are elevated by treatment with dapagliflozin, this was due to increased concentrations of the less atherogenic lb LDL-C. However, these findings were not observed after treatment with dipeptidyl peptidase-4 inhibitor, sitagliptin. Trial registration UMIN Clinical Trials Registry (UMIN000020984).

To assess the efficacy and safety of dapagliflozin as add-on therapy in patients with type 2 diabetes who were inadequately controlled with a dipeptidyl peptidase-4 inhibitor with or without metformin.. In this 24-week, multicenter, randomized, double-blind, placebo-controlled, parallel-group, phase 3 study with a 24-week blinded extension period, 432 patients were randomized to receive dapagliflozin 10 mg/day or placebo added to sitagliptin (100 mg/day) ± metformin (≥1,500 mg/day).. Baseline HbA1c and FPG levels were 7.9% (63.0 mmol/mol) and 162.2 mg/dL (9.0 mmol/L) for the dapagliflozin group and 8.0% (64.0 mmol/mol) and 163 mg/dL (9.0 mmol/L) for placebo. At week 24, dapagliflozin significantly reduced mean HbA1c levels (-0.5% [-4.9 mmol/mol]) versus placebo (0.0% [+0.4 mmol/mol]). Dapagliflozin reduced body weight versus placebo (-2.1 and -0.3 kg) and reduced HbA1c levels in patients with baseline values ≥8.0% (-0.8% [8.7 mmol/mol] and 0.0% [0.3 mmol/mol]) and fasting plasma glucose levels (-24.1 mg/dL [-1.3 mmol/L] and 3.8 mg/dL [0.2 mmol/L]). Similar results were observed when data were stratified by background therapy. Glycemic and weight benefits observed at week 24 were maintained through week 48. Changes from baseline in systolic blood pressure at week 8 were not significantly different between treatment groups. Over 48 weeks, fewer patients receiving dapagliflozin were discontinued or rescued for failing to achieve glycemic targets compared with placebo. Adverse events were balanced between groups, and discontinuation rates were low. At week 48, signs and symptoms suggestive of genital infection were more frequent with dapagliflozin (9.8%) than with placebo (0.4%). Signs and symptoms suggestive of urinary tract infection were balanced between dapagliflozin (6.7%) and placebo (6.2%).. These results suggest that in patients with type 2 diabetes, inadequately controlled on sitagliptin with or without metformin, add-on treatment with dapagliflozin provides additional clinical benefit and is well tolerated.

Dapagliflozin increases urinary glucose excretion by selectively inhibiting renal sodium-glucose transporter 2, an insulin-independent mechanism of action that may be complementary to that of other oral antidiabetes drugs. The current studies assessed the potential for pharmacokinetic (PK) interaction between dapagliflozin and pioglitazone, metformin, glimepiride or sitagliptin in healthy subjects following single-dose administration.. In open-label, randomized, three-period, three-treatment crossover studies, 24 subjects received 50 mg dapagliflozin, 45 mg pioglitazone or the combination, while 18 subjects received 20 mg dapagliflozin, 1000 mg metformin or the combination. In an open-label, randomized, five-period, five-treatment, unbalanced crossover study, 18 subjects first received 20 mg dapagliflozin, 4 mg glimepiride or the combination, and afterward 100 mg sitagliptin or sitagliptin plus 20 mg dapagliflozin. Blood samples were taken over 72 h of each treatment period. Lack of PK interaction was defined as the ratio of geometric means and 90% confidence interval (CI) for combination:monotherapy being within the range of 0.80-1.25.. Co-administration of dapagliflozin with pioglitazone, metformin, glimepiride or sitagliptin had no effect on dapagliflozin maximum plasma concentration (C(max) ) or area under the plasma concentration-time curve (AUC). Similarly, dapagliflozin did not affect the C(max) or AUC for the co-administered drug, except for slight extensions of the 90% CI for the ratio of geometric means for glimepiride AUC (upper limit 1.29) and pioglitazone C(max) (lower limit 0.75). All monotherapies and combination therapies were well tolerated.. Dapagliflozin can be co-administered with pioglitazone, metformin, glimepiride or sitagliptin without dose adjustment of either drug.

The effectiveness of sodium-glucose cotransporter 2 inhibitors (SGLT2i) in patients with heart failure (HF) in routine clinical practice is not extensively studied. This study aimed to evaluate the comparative effectiveness of SGLT2i vs. sitagliptin in older adults with HF and type 2 diabetes and to investigate whether there were any differences between agents within the SGLT2i class or for reduced and preserved ejection fraction.. Using Medicare claims data (April 2013 to December 2019), 16 253 SGLT2i initiators vs. 43 352 initiators of sitagliptin aged ≥65 years with type 2 diabetes and HF were included. The primary outcome was a composite of all-cause mortality, hospitalization for HF or urgent visit requiring intravenous diuretics; secondary outcomes included its individual components. Propensity score fine stratification weighted Cox regression was used to adjust for 100 pre-exposure characteristics. Mean age was 74 years; 49.8% were women. Initiation of SGLT2i vs. sitagliptin was associated with a lower risk of the primary composite outcome [adjusted hazard ratio (HR) 0.72; 95% confidence interval 0.67-0.77]. The adjusted HRs were 0.70 (0.63-0.78) for all-cause mortality, 0.64 (0.58-0.70) for hospitalization for HF, and 0.77 (0.69-0.86) for urgent visit requiring intravenous diuretics. Similar associations with the primary composite outcome were observed for all three agents within the SGLT2i class, for reduced and preserved ejection fraction, and subgroups based on demographics, comorbidities, and other HF treatments. Bias-calibrated HRs for the primary endpoint using negative and positive control outcomes ranged between 0.81 and 0.89, suggesting that the observed benefit could not be fully explained by residual confounding.. In routine US clinical practice, SGLT2i demonstrated robust clinical effectiveness in older adults with HF and type 2 diabetes compared with sitagliptin, with no evidence of heterogeneity across the SGLT2i class or across ejection fraction.

Compare the efficacy and safety of sitagliptin, dapagliflozin, and lobeglitazone in patients with uncontrolled type 2 diabetes, despite metformin and sulfonylurea therapy.. The study randomized patients into three groups, receiving sitagliptin 100 mg, dapagliflozin 10 mg, or lobeglitazone 0.5 mg daily (n = 26 each) and monitored changes in biochemical parameters and body composition for 24 months. The primary efficacy endpoint was changes in HbA1c at 24 months.. The mean change in HbA1c in the sitagliptin, dapagliflozin, and lobeglitazone groups was -0.81 ± 0.21%, -1.05 ± 0.70%, and -1.08 ± 0.98%, after 24 months. Dapagliflozin treatment significantly lowered systolic blood pressure by 5.5 mmHg and alanine aminotransferase levels. Dapagliflozin and lobeglitazone treatment significantly reduced proteinuria and insulin resistance. Dapagliflozin decreased whole body fat percentage by 1.2%, whereas sitagliptin and lobeglitazone increased it by 1.1% and 1.8%, respectively. Whole body muscle percentage increased in the dapagliflozin group and decreased in the lobeglitazone group. The safety profiles of the three treatments were comparable.. All three drugs displayed good glucose-lowering efficacy and comparable safety profiles. However, dapagliflozin therapy produced favorable changes in body composition. Dapagliflozin may be a suitable adjunct therapy for patients with type 2 diabetes seeking to improve their body composition.

Control of hyperglycemia and prevention of glucose reabsorption (glucotoxicity) are important objectives in the management of type 2 diabetes. This study deals with an oral combined dosage form design for two anti-diabetic drugs, sitagliptin and dapagliflozin using self-nanoemulsifying drug delivery systems (SNEDDS). The SNEDDS were developed using naturally obtained bioactive medium-chain/long-chain triglycerides oil, mixed glycerides and nonionic surfactants, and droplet size was measured followed by the test for antioxidant activities. Equilibrium solubility and dynamic dispersion experiments were conducted to achieve the maximum drug loading. The

BACKGROUND The current study aimed to compare the effects of dapagliflozin and sitagliptin on insulin resistant and body fat distribution in newly diagnosed type 2 diabetic patients. MATERIAL AND METHODS This study was an open-label, parallel controlled study. Patients were included if they were newly diagnosed with type 2 diabetes (<6 months) and had been receiving dapagliflozin or sitagliptin for 12 weeks in combination with a stable dose of metformin in the last month. At baseline and 12 weeks, insulin resistant (homeostatic model assessment of insulin resistance [HOMA-IR]), body fat distribution (waist/hip ratio), fasting blood glucose (FBG), glycated hemoglobin A1c (HbA1c), lipid profiles, and C-reactive protein (CRP) level were compared. RESULTS There were 59 patients receiving dapagliflozin and 67 patients receiving sitagliptin. There was no significant between-group difference in baseline characteristics. After 12 weeks of treatment, compared to the sitagliptin group, the FBG (6.4±0.5 versus 6.7±0.7 mmol/L), HbA1c (7.0±0.4 versus 7.2±0.5%), HOMA-IR (1.6±0.5 versus 1.8±0.6), triglyceride (1.6±0.4 versus 1.8±0.3 mmol/L), and CRP (3.1±0.7 versus 3.3±0.5 mg/L) were slightly lower in the dapagliflozin group. Within each group, compared to baseline, FBG (dapagliflozin [6.4±0.5 versus 7.8±0.7 mmol/L]; sitagliptin [6.7±0.7 versus 7.7±0.6 mmol/L]), HbA1c (dapagliflozin [7.0±0.4 versus 8.0±0.5%]; sitagliptin [7.2±0.5 versus 8.1%±0.6%]), HOMA-IR (dapagliflozin [1.6±0.5 versus 2.4±0.4]; sitagliptin [1.8±0.6 versus 2.5±0.4]), triglyceride (dapagliflozin [1.6±0.4 versus 2.2±0.5 mmol/L]; sitagliptin [1.8±0.3 versus 2.1±0.5 mmol/L]), and CRP (dapagliflozin [3.1±0.7 versus 6.2±1.1 mg/L]; sitagliptin [3.3±0.5 versus 6.1±1.0 mg/L]) were significantly decreased. CONCLUSIONS Dapagliflozin and sitagliptin had comparable effects on improving insulin resistant and blood glucose control, and these benefits may be associated with improvement of systemic inflammation.

To compare healthcare costs and utilization in patients with type 2 diabetes (T2D) who initiated dapagliflozin (DAPA) with costs and utilization in those who initiated sitagliptin (SITA) in a real-world setting.. This was a retrospective study of health plan enrollees in two US commercial claims databases or Medicare Part D. The study population comprised adult patients with T2D who initiated DAPA or SITA between January 1, 2014 and April 30, 2015. DAPA and SITA initiators were propensity-score-matched, and healthcare utilization and costs during the 1-year follow-up period were compared. Analyses were conducted separately for patients with evidence of oral antidiabetic drug (OAD) monotherapy use at baseline.. A total of 2722 patients were included in each matched cohort. Follow-up unadjusted all-cause costs ($16 065 and $17 281; P = 0.135) and diabetes-related costs ($9697 and $9354; P = 0.539) were similar in the DAPA and SITA cohorts. Higher office and outpatient visit costs in the SITA group were offset by higher pharmacy costs in the DAPA group. In the subgroup of 1804 patients with OAD monotherapy use at baseline, patients in the SITA group had higher total all-cause costs compared with those in the DAPA group ($14 884 vs. $12 353; P = 0.026).. Patients who initiated DAPA or SITA had similar all-cause and diabetes-related healthcare costs over 1 year of follow-up. In the subgroup of patients treated with OAD monotherapy at baseline (84% metformin monotherapy), those who initiated DAPA as add-on therapy had lower costs than patients who added SITA.

The impact of new classes of glucose lowering medications on markers of non-alcoholic fatty liver disease (NAFLD) associated with type 2 diabetes (T2D) have been inconsistent in their magnitude and independence. This large retrospective study investigates changes in alanine aminotransferase (ALT) levels among subjects initiated on newer classes of T2D medications in comparison to a reference control group.. We studied people with T2D from a large Canadian diabetes register, who had canagliflozin, dapagliflozin, liraglutide, sitagliptin or no further treatment added to their diabetes treatments. Stepwise multiple regression was used to determine the association of A1c and weight change on ALT. Propensity score weighting was used to balance baseline characteristics between treatment groups.. A total of 3667 subjects met study criteria. ALT levels (mean follow-up 4.8 months) were lower after treatment with sodium glucose co-transporter 2 (SGLT2) inhibitors, canagliflozin (-4.3U/L, P<0.01) and dapagliflozin (-3.5U/L, P<0.01), compared to incretin agents, liraglutide (-2.1U/L, P<0.01) and sitagliptin (-1.8U/L, P<0.01), each greater than the control group. Only the SGLT2 inhibitor treatment groups maintained a significant ALT reduction vs. control following multivariable adjustment and propensity score weighting. Greater ALT reductions were seen with higher baseline ALT for both the SGLT2 inhibitor treatment groups.. SGLT2 inhibitors canagliflozin and dapagliflozin resulted in a weight and A1c-independent reduction of ALT levels compared to incretin agents, with a dose-response observed at higher baseline ALT levels. Further studies investigating the differential effects of these drug classes on NAFLD, and insulin/glucagon levels as potential mechanism explaining these differences, should be performed.
