Abstract
Background Type 2 diabetes mellitus (T2DM) patients commonly undergo metformin monotherapy. This study aims to compare the efficacy, safety, and tolerability of combination therapy of dapagliflozin plus linagliptin versus dapagliflozin plus vildagliptin as add-on therapy in T2DM patients inadequately controlled on metformin. Methodology This was an 18-week, multicenter, randomized, double-blind, active-controlled, parallel-group, phase III clinical study. About 236 participants were randomly assigned to receive either a fixed-dose combination of dapagliflozin 10 mg plus linagliptin 5 mg tablets or a fixed-dose combination of dapagliflozin 10 mg plus vildagliptin SR 100 mg tablets added to metformin monotherapy. The primary outcome was the mean change in hemoglobin A1c (HbA1c) from baseline to the end of week 16. The key secondary endpoints were mean change in postprandial blood glucose (PPBG), fasting blood glucose (FBG), body weight, and the proportion of participants achieving HbA1c less than 7.0%. Results The dapagliflozin/linagliptin combination therapy showed a more significant change in HbA1c from baseline to the end of 16 weeks (mean reduction: -1.59% vs. -1.25%) compared to dapagliflozin/vildagliptin (p < 0.0001). Additionally, compared to the dapagliflozin/vildagliptin group, the dapagliflozin/linagliptin group demonstrated a significant reduction in both PPBG (mean reduction: -59.99 mg/dL vs. -55.34 mg/dL) and FPG (mean reduction: -32.91 mg/dL vs. -26.78 mg/dL). A total of 18 adverse events were reported in 17 (7.20%) participants, all of which were mild and resolved completely. There were no serious adverse events. Conclusions Compared to dapagliflozin and vildagliptin combination therapy, dapagliflozin and linagliptin fixed-dose combination provided clinically significant improvements in glycemic control. Because of its effectiveness, safety, and tolerability, the fixed-dose combination of dapagliflozin and linagliptin was a better option for treating T2DM patients who had previously only received metformin monotherapy.

A Multicenter, Randomized, Open-Label Study to Compare the Effects of Gemigliptin Add-on or Escalation of Metformin Dose on Glycemic Control and Safety in Patients with Inadequately Controlled Type 2 Diabetes Mellitus Treated with Metformin and SGLT-2 Inhibitors (SO GOOD Study). J Diabetes Res 2024; 2024:8915591. [PMID: 38223523 PMCID: PMC10787050 DOI: 10.1155/2024/8915591] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/01/2023] [Revised: 12/12/2023] [Accepted: 12/19/2023] [Indexed: 01/16/2024] Open
Abstract
Background We aimed to compare efficacy and safety between gemigliptin add-on and escalation of the metformin dose in patients with inadequately controlled type 2 diabetes mellitus (T2DM) despite treatment with metformin and SGLT2 inhibitors. Methods This study was a multicenter, randomized, open-label, active-controlled, parallel-group comparative study. Patients with T2DM uncontrolled on metformin and SGLT2 inhibitors were randomized to receive gemigliptin 50 mg as an add-on (GEM group, n = 37) or escalation of the metformin dose (500 mg, MET group, n = 38) for 24 weeks. The primary endpoint was the change in glycosylated hemoglobin (HbA1c) from baseline to week 24. Results At weeks 12 and 24, the reduction in HbA1c levels was significantly greater in the GEM group than in the MET group (GEM vs. MET = -0.64% ± 0.34% vs. -0.36% ± 0.50%, p = 0.009 at week 12; -0.61% ± 0.35% vs. -0.33% ± 0.70%, p = 0.045 at week 24). The proportions of patients who achieved target HbA1c levels of <7.0% at weeks 12 and 24 and <6.5% at week 12 were greater in the GEM group than in the MET group. An index of β-cell function was also significantly improved in the GEM group. The safety profiles were similar between the two groups. Conclusions Gemigliptin add-on therapy may be more effective than metformin dose escalation in patients with T2DM insufficiently controlled using metformin and SGLT2 inhibitors, without safety concerns. This trial is registered with CRIS_number: KCT0003520.

Abstract
INTRODUCTION The aim of the study was to evaluate the efficacy and safety of fixed-dose combination (FDC) of dapagliflozin (10 mg) and linagliptin (5 mg) in comparison to linagliptin 5 mg (Trajenta) in patients with insufficiently controlled type 2 diabetes mellitus (T2DM) on metformin monotherapy. METHODS The double-blind, randomized, multicentric, parallel-group phase III trial screened 287 adult patients with T2DM (age 18-65 years) from 16 sites across India. The recruited subjects were undergoing metformin monotherapy ≥ 1000 mg/day for at least 28 days. Patients with HbA1c of 7.5-10.5% (58-91 mmol/l) (n = 232) after 2 weeks of run-in period with linagliptin monotherapy and placebo dapagliflozin/linagliptin on metformin monotherapy were randomized (1:1) in parallel to once daily dapagliflozin/linagliptin 10/5 mg or linagliptin 5 mg for 16 weeks. Patients were stratified on the basis of HbA1c (≤ 9.0% and > 9.0%; ≤ 75 mmol/l and > 75 mmol/l)). A total of 225 subjects completed 16 weeks of treatment, 115 patients in the test group and 110 patients in the reference group. RESULTS Dapagliflozin/linagliptin (p = 0.0003) exhibited a greater change in HbA1c from baseline than linagliptin (p < 0.0001) in 16 weeks (mean reduction, - 1.28% vs - 0.83%). Test group showed a significant decrease in fasting plasma glucose (FPG), postprandial plasma glucose (PPG) and body weight compared to the reference group. The FDC was well tolerated with adverse events being more frequent in the reference group. No serious adverse events (SAEs) were reported in the study. CONCLUSION Dapagliflozin/linagliptin combination is a novel dipeptidyl peptidase 4 (DPP4)/sodium-glucose co-transporter 2 (SGLT2) inhibitor FDC approved in India for patients with T2DM. Potential limitations of this study are a small dose of dapagliflozin (10 mg) in the FDC, a short study duration (30 weeks) and a high minimum threshold for HbA1c (≤ 7.5%; ≤ 53 mmol/l). Results indicate the FDC to be a superior therapeutic option over linagliptin for patients with T2DM on metformin monotherapy. TRIAL REGISTRATION CTRI/2022/08/044563; 01/08/2022.

The Real DAPSI: A Real-World Retrospective Study on Assessing the Efficacy and Safety of a Fixed-Dose Combination of Dapagliflozin and Sitagliptin in the Indian Population. Cureus 2023; 15:e46767. [PMID: 37954782 PMCID: PMC10632527 DOI: 10.7759/cureus.46767] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 10/07/2023] [Indexed: 11/14/2023] Open
Abstract
Introduction Type 2 diabetes mellitus (T2DM) is a chronic metabolic disorder affecting millions of individuals worldwide. Effective management of T2DM is crucial to prevent complications. Dapagliflozin and sitagliptin are oral anti-diabetic agents that have been shown to provide synergistic effects in controlling blood glucose levels. However, there is limited data on the efficacy and safety of the dapagliflozin-sitagliptin fixed-dose combination (FDC) in the Indian population. This study aimed to evaluate the real-world effectiveness and safety of the dapagliflozin-sitagliptin FDC in the Indian population. Methods This was a retrospective study conducted at healthcare centers in India. The study included patients with T2DM who were prescribed a FDC of dapagliflozin and sitagliptin. Data were collected from the medical health records of patients, including demographics, baseline glycated hemoglobin (HbA1c), blood glucose levels, BMI, blood pressure, and adverse events. The primary outcome was the change in HbA1c, postprandial plasma glucose (PPG), and fasting plasma glucose (FPG) from baseline to 12 weeks after treatment initiation. Results A total of 358 patients were included in the study, with a mean age of 56.2 years. The majority of the patients were male (68.2%), and the mean baseline HbA1c was 8.9 ± 0.87%. After 12 weeks of treatment with dapagliflozin and sitagliptin, there was a significant reduction in HbA1c levels from 8.9 to 7.2 (p <0.0001). There was also a significant reduction in fasting blood glucose levels from 178.8 to 124.0 (p <0.0001) and postprandial blood glucose levels from 273.9 to 176.0 (p <0.0001). There were no serious adverse events reported during the study period. Conclusion The FDC of dapagliflozin and sitagliptin is effective and safe in reducing blood glucose levels and BMI in the Indian population with T2DM. This real-world retrospective study provides valuable insights into the clinical effectiveness and safety of dapagliflozin-sitagliptin FDC in the Indian population. These findings highlight the potential benefits of this combination therapy in managing T2DM and pave the way for optimized treatment strategies and improved patient outcomes in the Indian healthcare landscape. Clinicians may consider dapagliflozin-sitagliptin FDC as a viable treatment option for T2DM patients.

Endocr Pract 2023:S1530-891X(23)00367-1. [PMID: 37037286 DOI: 10.1016/j.eprac.2023.04.001] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/23/2023] [Revised: 03/31/2023] [Accepted: 04/02/2023] [Indexed: 04/12/2023]
Abstract
OBJECTIVE The cardiovascular (CV) and renal benefits of SGLT-2 inhibitors (SGLT2i) in people with type 2 diabetes (T2D) are well known. However, similar beneficial effects of SGLT2i in combination with DPP-4 inhibitors (DPP4i) are not known. It is of interest to explore a trial-level meta-analysis to find out this knowledge gap. METHODS A literature search was carried out in PubMed and Embase databases until January 31, 2023. All CV outcome trials (CVOTs) reporting the CV and renal outcomes of SGLT2i with or without background DPP4i therapy against the placebo were retrieved. A meta-analysis was subsequently conducted by applying the inverse variance-weighted averages of pooled logarithmic hazard ratio using random effects analysis, primarily. RESULTS This meta-analysis showed that the beneficial three-point major adverse cardiovascular events (3P-MACE) composite (three CVOTs; N = 32,418), the composite of CV death or heart failure hospitalization (hHF) (four CVOTs; N = 37,687), hHF (three CVOTs; N = 27,545), CV death (four CVOTs; N = 34,565), and renal outcomes (two CVOTs; N = 25,406) with SGLT2i are similar with or without background DPP4i therapy against the placebo (Pheterogeneity = 0.71, 0.07, 0.87, 0.72, and 0.25; respectively). However, against the placebo, the summary estimates for 3P-MACE composite, hHF, and renal outcomes were stronger with SGLT2i alone whilst the summary estimates for CV death or hHF composite were larger with SGLT2i with background DPP4i therapy. CONCLUSION Beneficial CV and renal effects of SGLT2i are similar against placebo regardless of background DPP4i therapy.
