Trelagliptin (SYR-472) is a selective inhibitor of DPP-4 and is developed for the treatment of type 2 diabetes mellitus (T2DM) [1].
Dipeptidyl peptidase (DPP)-4 also known as adenosine deaminase complexing protein 2 or CD26 is an antigenic enzyme that expressed on the surface of most cell types and plays an important role in regulating immune system, signal transduction and apoptosis [2, 3].
Trelagliptin (SYR-472) is a potent DPP-4 inhibitor and can be administered once weekly which unlike its other class approved agents that be taken once daily [1]. In Japan, clinical trials had been conducted to detect the effectiveness of Trelagliptin by comparing with the approved medicine—alogliptin and it was shown that Trelagliptin once-weekly exhibited similar efficacy and safety to alogliptin once daily, which indicated that Trelagliptin could be a useful new antidiabetes drug that needs to be given once a week [2].
Trelagliptin (SYR-472) has been used in phase 2 and phase 3 clinical trials for the treatment of patients with T2DM showed similar efficacy and safety to alogliptin once daily and produced clinically and statistically significant improvements in glycaemic control with well tolerated in Japan [2, 3].

Identification, characterization and HPLC quantification of process-related impurities in Trelagliptin succinate bulk drug: Six identified as new compounds.[Pubmed:27209451]
J Pharm Biomed Anal. 2016 Sep 5;128:18-27.
A sensitive, selective and stability indicating reversed-phase LC method was developed for the determination of process related impurities of Trelagliptin succinate in bulk drug. Six impurities were identified by LC-MS. Further, their structures were characterized and confirmed utilizing LC-MS/MS, IR and NMR spectral data. The most probable mechanisms for the formation of these impurities were also discussed. To the best of our knowledge, six structures among these impurities are new compounds and have not been reported previously. The superior separation was achieved on an InertSustain C18 (250mmx4.6mm, 5mum) column in a gradient mixture of acetonitrile and 20mmol potassium dihydrogen phosphate with 0.25% triethylamine (pH adjusted to 3.5 with phosphate acid). The method was validated as per regulatory guidelines to demonstrate system suitability, specificity, sensitivity, linearity, robustness, and stability.
A rapid and sensitive UHPLC-MS/MS assay for the determination of trelagliptin in rat plasma and its application to a pharmacokinetic study.[Pubmed:27561183]
J Chromatogr B Analyt Technol Biomed Life Sci. 2016 Oct 15;1033-1034:166-171.
This study aims to develop and validate a simple, rapid and sensitive ultra-performance liquid chromatography with tandem mass spectrometry (UHPLC-MS/MS) method for exploring pharmacokinetic characteristics of Trelagliptin. Protein precipitation by acetonitrile was used to prepare plasma sample. A RRHD Eclipse Plus C18 (2.1x50mm, 1.8mu) column with gradient mobile phase (containing acetonitrile and 0.1% formic acid) help to achieve the separation of Trelagliptin and carbamazepine (IS) with high selectivity. Detection of target fragment ions m/z 358.2-->133.9 for Trelagliptin, and m/z 237.1-->194.0 for IS was performed in positive-ion electrospray ionization mass spectrometry by multiple reaction monitoring. Linear calibration plots were achieved in the range of 5-4000ng/mL for Trelagliptin (R(2)=0.999) in rat plasma. The recovery of Trelagliptin ranged from 87.8% to 93.7%. The method was showed to be accurate, precise and stable. No obvious matrix effect was found. It has been fully validated and successfully applied to pharmacokinetic study of Trelagliptin.
Trelagliptin (SYR-472, Zafatek), Novel Once-Weekly Treatment for Type 2 Diabetes, Inhibits Dipeptidyl Peptidase-4 (DPP-4) via a Non-Covalent Mechanism.[Pubmed:27328054]
PLoS One. 2016 Jun 21;11(6):e0157509.
Trelagliptin (SYR-472), a novel dipeptidyl peptidase-4 inhibitor, shows sustained efficacy by once-weekly dosing in type 2 diabetes patients. In this study, we characterized in vitro properties of Trelagliptin, which exhibited approximately 4- and 12-fold more potent inhibition against human dipeptidyl peptidase-4 than alogliptin and sitagliptin, respectively, and >10,000-fold selectivity over related proteases including dipeptidyl peptidase-8 and dipeptidyl peptidase-9. Kinetic analysis revealed reversible, competitive and slow-binding inhibition of dipeptidyl peptidase-4 by Trelagliptin (t1/2 for dissociation approximately 30 minutes). X-ray diffraction data indicated a non-covalent interaction between dipeptidyl peptidase and Trelagliptin. Taken together, potent dipeptidyl peptidase inhibition may partially contribute to sustained efficacy of Trelagliptin.
Effect of trelagliptin on vascular endothelial functions and serum adiponectin level in patients with type 2 diabetes: a preliminary single-arm prospective pilot study.[Pubmed:27809903]
Cardiovasc Diabetol. 2016 Nov 4;15(1):153.
BACKGROUND: Trelagliptin, an oral DPP-4 inhibitor, which is administered once per week and characterized by a long half-life in blood. The effects of Trelagliptin on vascular endothelial functions have not been clarified to date. The objective of the present study was to examine the effects of Trelagliptin on vascular endothelial functions in patients with type 2 diabetes mellitus (DM) using flow-mediated dilatation (FMD), adiponectin, and asymmetric dimethylarginine (ADMA) as evaluation indicators. METHODS: This study was a preliminary single-arm prospective pilot study. The subjects of this study were type 2 DM patients aged 20-74 years, who visited our outpatient department. The patients were treated with Trelagliptin, and their FMD, adiponectin, and ADMA levels were measured at baseline and at 12 weeks after initial treatment to determine the changes during the study period. RESULTS: A total of 27 patients, excluding three dropouts, were included in the population for analysis. Trelagliptin treatment showed no significant changes in FMD (2.42 +/- 2.7% at baseline vs. 2.66 +/- 3.8% post-treatment, P = 0.785) and ADMA (0.41 +/- 0.0 microg/mL at baseline vs. 0.40 +/- 0.0 microg/mL post-treatment, P = 0.402). Trelagliptin treatment resulted in a significant increase of serum adiponectin level (7.72 +/- 6.9 microg/mL at baseline vs. 8.82 +/- 8.3 microg/mL post-treatment, P < 0.002). CONCLUSIONS: In this pilot study, Trelagliptin treatment showed no significant changes in FMD. On the other hand, it was believed that Trelagliptin treatment may increase serum adiponectin level.
