Evaluation of the Safety and Efficacy of Teneligliptin at a Higher Dose in Indian Type 2 Diabetes Patients: A Retrospective Analysis

Pleiotropic effect of teneligliptin versus glimepiride add-on therapy on hs-CRP and cardiorenal parameters in Indian type 2 diabetes patients: An open-labeled randomized controlled trial

Objective

The objective of the study was to estimate the pleiotropic effect of teneligliptin on high-sensitivity C-reactive protein (hs-CRP) levels and some cardiorenal parameters in comparison to glimepiride, both as add-on therapy to metformin.

Methodology

This 12-week open-label, parallel-group, randomized controlled trial was conducted among Indian people with type 2 diabetes mellitus and on metformin monotherapy with poor glycemic control (glycated hemoglobin >7% or 53 mmol/mol). The endpoints were mean change in hs-CRP levels, systolic blood pressure (SBP), diastolic blood pressure (DBP), serum creatinine, blood urea, estimated glomerular filtration rate (eGFR), and change in cardiovascular (CV) risk categories from baseline to end of 12 weeks.

Results

Seventy participants were randomized (1:1) to receive either teneligliptin 20 mg once daily (n = 35) or glimepiride 1 mg twice daily (BD) (n = 35) as an add-on to metformin 500 mg BD. The mean age of the participants was 50.65 and 50.7 years in arms 1 and 2, respectively. At 12-weeks end, teneligliptin add-on caused a statistically significant reduction in hs-CRP compared to glimepiride in both per-protocol (PP) and intention-to-treat (ITT) sets. No significant difference was observed for changes in SBP and DBP, creatinine, urea, eGFR levels, and CV risk category in both PP and ITT sets.

Conclusion

Teneligliptin add-on resulted in favorable effects on hs-CRP levels and comparable effects on cardiorenal parameters compared to glimepiride add-on therapy at 12-weeks end.This trial has been prospectively registered in CTRI (Clinical Trials Registry of India). Registration number: CTRI/2021/08/035342.

Comprehensive safety profile of dipeptidyl peptidase-4 inhibitors: a post-marketing study based on FAERS database using signal detection algorithms

BACKGROUND

Dipeptidyl peptidase-4 inhibitors (DPP-4 inhibitors) have acquired a foothold in managing type 2 diabetes mellitus, but few concerns have arisen regarding their overall safety profile. The aim of this study is to assess the potential risk of DPP-4 inhibitors by analyzing data from the FDA Adverse Event Reporting System (FAERS) database.

RESEARCH DESIGN AND METHODS

This is a retrospective study which explored the FAERS database till March 2023 for the collection of safety reports. The disproportionality analysis was performed using signal detection algorithms (SDAs) incorporating frequentist-based data mining approach such as relative reporting ratio (RRR), reporting odds ratio (ROR) and proportional reporting ratio (PRR) with 95% confidence interval (CI).

RESULTS

A total of 14,573 adverse event reports were reported in the FAERS public dashboard associated with all the included DPP-4 inhibitors. The computed PRR, ROR, and RRR indicated positive signals for DPP-4 inhibitors with cardiac failure, pancreatitis, pemphigoid, hypoglycemia, acute kidney injury and lactic acidosis. Saxagliptin showed a higher signal score for cardiac failure, while sitagliptin was more associated with pancreatitis. Moreover, alogliptin exhibited an elevated signal score associated with pancreatic carcinoma.

CONCLUSION

Several significant disproportionality signals were observed with DPP-4 inhibitors. However, clinicians have to consider the comorbidities and concomitant drugs while prescribing these drugs.
