A new fast LC-MS/MS method was developed for determination of alogliptin and pioglitazone in human plasma. Linearity ranges of 10-400ngmL(-1) for alogliptin and 25-2000ngmL(-1) for pioglitazone, were found to be suitable for their bioanalysis covering the Cmin and Cmax values of the drugs. Direct precipitation technique was used for simultaneous extraction of the drugs successfully from human plasma samples. Chromatographic separation was achieved on a BEH C18 column (50mm×2.1mm, 1.7μm) with 0.1% aqueous formic acid: acetonitrile (40:60, v/v) at a flow rate of 0...

Type 2- diabetes mellitus (T2DM) represents a major risk factor for cardiovascular complications and mortality. Strict glucose control in the early course of the disease prevents cardiovascular complications only in the long run. Non-medical therapies (diet, exercise, body weight reduction) bear little evidence for positive cardiovascular effects.Bariatric surgery is not number one choice in therapy of T2DM. Metformin seems to provide positive cardiovascular effects. Insulin seems to be cardiovascular neutral, as well as the DPP4-inhibitors Saxagliptin, Sitagliptin and Alogliptin...

BACKGROUND: There is increasing evidence implicating atrial mitochondrial dysfunction in the pathogenesis of atrial fibrillation. In this study, we explored whether alogliptin, a dipeptidyl peptidase-4 inhibitor, can prevent mitochondrial dysfunction and atrial remodeling in a diabetic rabbit model. METHODS AND RESULTS: A total of 90 rabbits were randomized into 3 groups as follows: control group (n=30), alloxan-induced diabetes mellitus group (n=30), and alogliptin-treated (12...

PURPOSE: The cardiovascular safety outcomes of newer antidiabetic agents were reviewed. SUMMARY: Seven randomized, placebo-controlled trials involving patients with type 2 diabetes mellitus with or at risk for cardiovascular disease were reviewed. The trials examined the cardiovascular safety outcomes of the following agents: alogliptin, saxagliptin, and sitagliptin (dipeptidyl peptidase-4 [DPP-4] inhibitors); liraglutide, lixisenatide, and semaglutide (glucagon-like peptide-1 agonists); and empagliflozin (a sodium glucose cotransport-2 inhibitor)...

BACKGROUND: Given recent discrepant results from randomized controlled trials (RCTs), we examined the totality of RCT evidence assessing the association between dipeptidyl peptidase-4 (DPP-4) inhibitors and heart failure. METHODS: MEDLINE, Embase and ClinicalTrials.gov were searched without language restrictions to August 2016 for RCTs comparing DPP-4 inhibitors to placebo or no therapy for a period of 24 weeks or more. We included all heart failure outcomes when listed either as a serious adverse event or adverse event...

New multivariate and univariate methods were developed for the analysis of two novel gliptin combinations by manipulating the zero-order and ratio spectra of empagliflozin and linagliptin in combination, with application on Glyxambi(®) tablets, and of alogliptin and pioglitazone in combination, with application on Oseni(®) tablets. Linearity ranges for chemometric approaches using principal component regression and partial least-squares were found to be 2–10, 2.5–12.5, 5–15, and 5–25 μg/mL for empagliflozin, linagliptin, alogliptin, and pioglitazone, respectively, whereas the respective linearity ranges for the spectrophotometric approaches were found to be 5–15, 2–12, 5–15, and 5–15 μg/mL...

Dipeptidyl peptidase-4 inhibitors (DPP-4is), in addition to their antihyperglycemic roles, have antiatherosclerotic effects. We reported that sodium-glucose cotransporter 2 inhibitors (SGLT2is) suppress atherosclerosis in a glucose-dependent manner in diabetic mice. Here, we investigated the effects of combination therapy with SGLT2i and DPP-4i on atherosclerosis in diabetic mice. SGLT2i (ipragliflozin, 1.0 mg/kg/day) and DPP-4i (alogliptin, 8.0 mg/kg/day), either alone or in combination, were administered to db/db mice or streptozotocin-induced diabetic apolipoprotein E-null (Apoe(-/-) ) mice...

André J Scheen
Dipeptidyl peptidase-4 inhibitors (DPP-4is) and glucagon-like peptide-1 receptor agonists (GLP-1RAs) represent two distinct classes of incretin-based therapies used for the treatment of type 2 diabetes. Non-inferiority versus placebo was shown in large prospective cardiovascular outcome trials in patients with high cardiovascular risk: SAVOR-TIMI 53 (saxagliptin), EXAMINE (alogliptin), and TECOS (sitagliptin); ELIXA (lixisenatide), LEADER (liraglutide) and SUSTAIN 6 (semaglutide). The promises raised by meta-analyses of phase 2-3 trials with DPP-4is were non confirmed as no cardiovascular protection could be evidenced...

PURPOSE: Impaired β-cell function remains unaddressed in PCOS. The aim of the study was to evaluate whether dipeptidyl peptidase-4 (DPP-4) inhibitor alogliptin (ALO) alone or in combination with pioglitazone (PIO) improves β-cell function along with insulin resistance (IR) in metformin (MET) treated obese women with PCOS with persistent IR. MATERIALS AND METHODS: In 12-week randomized study, ALO 25 mg QD (n=15) or ALO 25 mg QD and PIO 30 mg QD (n=15) was added to MET 1000 mg BID in PCOS women (aged 34...

This study investigated the effects of switching from combination therapy with either alogliptin (Alo) or pioglitazone (Pio) to fixed-dose combination therapy (FDCT) with alogliptin and pioglitazone (Alo-Pio FDCT). The usefulness and efficacy of Alo-Pio FDCT were investigated. A total of 50 outpatients with type 2 diabetes mellitus (T2DM) treated with Alo and 47 outpatients with T2DM treated with Pio were switched to Alo-Pio FDCT, and its efficacy and usefulness were evaluated. Significant improvements were observed in hemoglobinA1c (HbA1c), alanine transaminase (ALT), and γ-glutamyl transpeptidase (GGT) levels after switching to Alo-Pio FDCT for 16 weeks in both groups...

In this paper, we review the results of large, double-blind, placebo-controlled randomized trials mandated by the US Food and Drug Administration to examine the cardiovascular safety of newly-approved antihyperglycemic agents in patients with type 2 diabetes. The cardiovascular effects of dipeptidyl peptidase-4 (DPP-4) inhibitors remain controversial: while these drugs did not reduce or increase the risk of primary, pre-specified composite cardiovascular outcomes, one DPP-4 inhibitor (saxagliptin) increased the risk of hospitalization for heart failure in the overall population; another (alogliptin) demonstrated inconsistent effects on heart failure hospitalization across subgroups of patients, and a third (sitagliptin) demonstrated no effect on heart failure...

INTRODUCTION: Alogliptin is an oral antihyperglycemic agent that is a selective inhibitor of the enzyme dipeptidyl peptidase-4 (DPP-4), approved for the treatment of type 2 diabetes mellitus (T2DM). There currently exists no comparative data to support the use of alogliptin in combination with metformin (met) and sulfonylurea (SU). A decision-focused network meta-analysis (NMA) was performed to compare the relative efficacy and safety of alogliptin 25 mg once daily to other DPP-4 inhibitors as part of a triple therapy regimen for patients inadequately controlled on metformin and SU dual therapy...

Background -We sought to describe the relationship between changes in high-sensitivity cardiac troponin I (hsTnI) and cardiovascular (CV) outcomes. Methods -The Examination of Cardiovascular Outcomes with Alogliptin versus Standard of Care (EXAMINE) was a phase IIIb clinical outcomes trial designed to evaluate the CV safety of alogliptin, a non-selective dipeptidyl peptidase 4 (DPP-4) inhibitor. Patients with type 2 diabetes mellitus (T2DM), glycated hemoglobin between 6.5%-11% (or 7%-11% if they were on insulin), and a recent acute coronary syndrome (between 15-90 days prior to randomization) were eligible for the trial...

In view of the significant cardiovascular (CV) morbidity and mortality in patients with type 2 diabetes mellitus, and concerns raised about the CV safety of some glucose-lowering drugs, the US Food and Drug Administration (FDA) issued guidance for the industry in 2008 to demonstrate CV safety for the approval of all new antihyperglycemic drugs. Seven randomized controlled trials involving around 60,000 participants have been completed so far and have demonstrated the CV safety of dipeptidyl peptidase 4 inhibitors (saxagliptin, alogliptin and sitagliptin), glucagon-like peptide-1 receptor agonists (lixisenatide, liraglutide and semaglutide) and a sodium-glucose co-transporter 2 inhibitor (empagliflozin) in patients with type 2 diabetes...

INTRODUCTION: Adiponectin is a pleiotropic adipocytokine with a strong inverse (protective) association with obesity, diabetes, and cardiovascular outcomes in stable patients. However, this relationship may be reversed in the setting of acute coronary syndrome (ACS). Given this possible complex relationship, we investigated adiponectin and cardiovascular (CV) outcomes in patients with diabetes and recent ACS. MATERIALS AND METHODS: We analyzed baseline adiponectin concentration and CV outcomes in 5,213 patients with type 2 diabetes enrolled 15-90 days (median 45 days) after ACS in the EXAMINE trial of alogliptin vs placebo...

Diabetes treatment should include drugs with absolutely no adverse effects toward cardiovascular risk. Indeed, it would be advisable to use drugs with intrinsic protective effect against the risk of cardiovascular events. Intervention trials aiming at demonstrating a protective cardiovascular effect of very tight glucose control have produced controversial results. It is commonly perceived, however, that early intervention with safe treatment strategies is likely to be beneficial. In regard to safety, in the attempt to firmly establish cardiovascular safety of new drugs for diabetes, Government Authorities have mandated that cardiovascular safety trials need to be performed for all new drugs registered for diabetes treatment...

Cardiovascular outcome trials of antihyperglycaemic drugs and non-statin LDL-cholesterol-lowering drugs in patients with type 2 diabetes who have, or who are at high risk of, atherosclerotic cardiovascular disease have provided new evidence that has substantially affected the management of cardiovascular risk in these patients. On the basis of proven cardiovascular and renal benefit, the antihyperglycaemic drugs empagliflozin, liraglutide, and semaglutide-the latter being under review for approval by the US Food and Drug Administration and the European Medicines Agency-should be preferentially used as second-line treatments in these patient populations, typically in addition to metformin...

Although the effects of dipeptidyl peptidase 4 (DPP-4) inhibitors beyond their hypoglycemic action have been reported, whether these inhibitors have renoprotective effects in nondiabetic chronic kidney disease (CKD) is unclear. We examined the therapeutic effects of DPP-4 inhibition in mice with unilateral ureteral obstruction (UUO), a nondiabetic model of progressive renal fibrosis. After UUO surgery, mice were administered either the DPP-4 inhibitor alogliptin or a vehicle by oral gavage once a day for 10 days...
