sitagliptin-phosphate and Weight-Gain

To compare the effectiveness of dulaglutide 1.5 and 0.75 mg with active comparators and placebo with regard to a composite endpoint of glycated haemoglobin (HbA1c), weight and hypoglycaemia, using post hoc analyses.. A logistic regression analysis was performed on the intention-to-treat population, using data from the last observation carried forward, and the composite endpoint of HbA1c <7.0% (53 mmol/mol), no weight gain (≤0 kg) and no hypoglycaemia (glucose <3.0 mmol/l or severe hypoglycaemia) after 26 weeks for each trial in the AWARD programme separately.. At 26 weeks, within each study, 37-58% of patients on dulaglutide 1.5 mg, 27-49% of patients on dulaglutide 0.75 mg, and 9-61% of patients on active comparators achieved the composite endpoint. Significantly more patients reached the composite endpoint with dulaglutide 1.5 mg than with metformin, sitagliptin, exenatide twice daily or insulin glargine: odds ratio (OR) 1.5 [95% confidence interval (CI) 1.0, 2.2; p < 0.05], OR 4.5 (95% CI 3.0, 6.6; p < 0.001), OR 2.6 (95% CI 1.8, 3.7; p < 0.001) and OR 7.4 (95% CI 4.4, 12.6; p < 0.001), respectively, with no difference between dulaglutide 1.5 mg and liraglutide 1.8 mg. In addition, significantly more patients reached the composite endpoint with dulaglutide 0.75 mg than with sitagliptin or insulin glargine: OR 3.3 (95% CI 2.2, 4.8; p < 0.001) and OR 4.5 (95% CI 2.7, 7.8; p < 0.001), respectively.. Dulaglutide is an effective treatment option, resulting in a similar or greater proportion of patients reaching the HbA1c target of <7.0% (53 mmol/mol), without weight gain or hypoglycaemia compared with active comparators.

The purpose of this study was to review the current literature and information on the combination product Juvisync™ (sitagliptin + simvastatin), which was approved by the US Food and Drug Administration in October 2011.. PubMed (2001-2014) was searched for primary and review articles on sitagliptin, simvastatin, or the combination product. Drug manufacturing data and product labeling were also used. Studies of simvastatin, sitagliptin, or the combination were screened and analyzed to include relevant and recent papers. Selected English language trials were limited to those with human subjects and included both safety and efficacy outcomes.. When compared with glipizide as add-on therapy to metformin, sitagliptin was noninferior but had lower rates of hypoglycemia and weight gain. In addition, when compared with insulin glargine, sitagliptin was less effective in decreasing glycosylated hemoglobin, but was associated with significantly lower rates of hypoglycemia. Further, trials have shown a beneficial effect of using statins in patients with diabetes mellitus with regard to decreasing cardiovascular risk, regardless of baseline lipid levels or the presence of a cardiac disease. Both medications have also demonstrated an acceptable side effect profile. However, caution is needed when coadministering with any drug that may increase simvastatin levels to reduce the risk of myopathy and rhabdomyolysis.. Juvisync should be used in patients requiring both sitagliptin and simvastatin. Both agents have shown good efficacy and acceptable safety profiles. Sitagliptin is a good option for diabetic patients to improve glycemic control with a lower risk of hypoglycemia and weight gain.

Dipeptidyl peptidase-4 (DPP-4) inhibitors offer new options for the management of type 2 diabetes. Direct comparisons with active glucose-lowering comparators in drug-naive patients have demonstrated that DPP-4 inhibitors exert slightly less pronounced HbA(1c) reduction than metformin (with the advantage of better gastrointestinal tolerability) and similar glucose-lowering effects as with a thiazolidinedione (TZD; with the advantage of no weight gain). In metformin-treated patients, gliptins were associated with similar HbA(1c) reductions compared with a sulphonylurea (SU; with the advantage of no weight gain, considerably fewer hypoglycaemic episodes and no need for titration) and a TZD (with the advantage of no weight gain and better overall tolerability). DPP-4 inhibitors also exert clinically relevant glucose-lowering effects compared with a placebo in patients treated with SU or TZD (of potential interest when metformin is either not tolerated or contraindicated), and as oral triple therapy with a good tolerability profile when added to a metformin-SU or pioglitazone-SU combination. Several clinical trials also showed a consistent reduction in HbA(1c) when DPP-4 inhibitors were added to basal insulin therapy, with no increased risk of hypoglycaemia. Because of the complex pathophysiology of type 2 diabetes and the complementary actions of glucose-lowering agents, initial combination of a DPP-4 inhibitor with either metformin or a glitazone may be applied in drug-naive patients, resulting in greater efficacy and similar safety compared with either drug as monotherapy. However, DPP-4 inhibitors were less effective than GLP-1 receptor agonists for reducing HbA(1c) and body weight, but offer the advantage of being easier to use (oral instead of injected administration) and lower in cost. Only one head-to-head trial demonstrated the non-inferiority of saxagliptin vs sitagliptin. Clearly, more trials of direct comparisons between different incretin-based therapies are needed. Because of their pharmacokinetic characteristics, pharmacodynamic properties (glucose-dependent glucose-lowering effect) and good overall tolerability profile, DPP-4 inhibitors may have a key role to play in patients with renal impairment and in the elderly. The role of DPP-4 inhibitors in the therapeutic armamentarium of type 2 diabetes is rapidly evolving as their potential strengths and weaknesses become better defined mainly through controlled clinical trials.

The aim of this study was to evaluate the effectiveness of sitagliptin, alone or in combination with metformin, in kidney transplant patients with newly diagnosed new-onset diabetes mellitus after transplant who had inadequate glycemic control, compared with a group of patients receiving insulin glargine with special emphasis on weight gain.. Newly diagnosed renal transplant patients with new-onset diabetes mellitus after a transplant was defined by a blood glucose ≥ 11.1 mmol/L after an oral glucose tolerance test were examined. They were treated with standard immunosuppression composed of triple therapy with tacrolimus or cyclosporine, mycophenolate mofetil or azathioprine, and prednisone. They had stable graft function for more than 6 months after the transplant.. Patients with new-onset diabetes mellitus after transplant (n=28) whose glycemia was not controlled adequately with oral hypoglycemic agents (either alone or in combination) received oral sitagliptin 100 mg once daily in addition to existing therapy for 12 weeks. Patients who received insulin glargine as add-on therapy (n=17) served as the control group. Data analyses included glycated hemoglobin, fasting plasma glucose, lipid profile, body weight, and the occurrence of hypoglycemia. We found significant reductions in glycated hemoglobin and fasting plasma glucose values after 12 weeks of additional sitagliptin therapy that were comparable to those with insulin glargine. While the addition of stagliptin resulted in a small weight loss (0.4 kg), the addition of insulin glargine resulted in a weight gain (0.8 kg). The overall incidence of adverse experiences was low and generally mild in both groups.. In a group of renal transplant recipients with new-onset diabetes mellitus after a transplant in whom glycemia was not controlled adequately by oral hypoglycemic agents, the addition of sitagliptin helped to achieve glycemic control similar to insulin glargine but with a marginal weight advantage.

Sitagliptin and glipizide added to metformin provided similar degrees of glycemic efficacy in patients with type 2 diabetes with inadequate glycemic control on metformin monotherapy at 1 year; however, significantly more patients in the sitagliptin group achieved an A1C reduction of >0.5% without hypoglycemia and without an increase in body weight.

There has been concern as to whether dipeptidyl peptidase-4 (DPP-4) inhibitors can be used safely in patients with relatively good glycemic control. This study, approved by the institutional review board of Hanzoumon Diabetes City Atlas Clinic, examined whether DPP-4 inhibitor sitagliptin could safely achieve good glycemic control without severe hypoglycemia by employing the "added food" concept. The subjects were 60 patients (46 men and 14 women) with type 2 diabetes who started sitagliptin therapy during a 1-month period from December 15, 2009 to January 15, 2010. They were recommended to have added food between meals to prevent hypoglycemia, while maintaining the same daily calorie intake. HbA(1c) decreased from 7.1 ± 1.2% to 6.5 ± 0.6% after 6 months of sitagliptin treatment (p < 0.001). In patients with a baseline HbA(1c) <7%, it decreased from 6.5 ± 0.3% to 6.1 ± 0.4% (p < 0.001). Systolic blood pressure was significantly reduced from 127.7 ± 17.0 to 122.7 ± 17.9 mmHg in the patients with a baseline HbA(1c) < 7% (p = 0.018). However, body weight increased by approximately 900 g and high-density lipoprotein cholesterol decreased significantly from 1.57 ± 0.46 to 1.43 ± 0.35 mmol/L (p < 0.01) in the patients concomitantly receiving sulfonylureas with sitagliptin. Excellent glycemic control was achieved by sitagliptin treatment together with the added food concept. However, combined use of sitagliptin with sulfonylureas requires attention to weight gain and the lipid profile. Further clinical studies will elucidate whether sitagliptin can decrease cardiovascular events as well as normalizing blood glucose and lowering the blood pressure.
