Linagliptin as add-on to empagliflozin in a fixed-dose combination in Japanese patients with type 2 diabetes: Glycaemic efficacy and safety profile in a two-part, randomized, placebo-controlled trial.

ABSTRACT: AIMS:This two-part, double-blind, double-dummy, randomized, placebo-controlled trial (83 sites) evaluated the efficacy and safety of empagliflozin (Empa) 10 or 25 mg and linagliptin (Lina) 5 mg fixed-dose combinations (FDCs) in Japanese patients with type 2 diabetes mellitus (T2DM) who were poorly controlled with Empa. MATERIALS AND METHODS:Patients (previously drug-naive or using one oral antidiabetic drug for ? 12 weeks) entered an open-label stabilization period (16 weeks, Empa 10 mg [Part A] or Empa 25 mg [Part B]). Subsequently, they received Empa 10 mg plus placebo (Plc) for Empa/Lina10/5 (Empa/Plc 10/5; Part A) or Empa 25 mg plus Plc for Empa/Lina 25/5 (Empa/Plc 25/5; Part B) for 2 weeks. Patients with HbA1c 7.5-10.0% were randomized (1:1) to a 24-week regimen of once-daily Empa/Lina 10/5 (n = 107) or Empa/Plc 10/5 (n = 108) in Part A, or to Empa/Lina 25/5 (n = 116) or Empa/Plc 25/5 (n = 116) in Part B, with a 28-week extension period in Part B. RESULTS:Change from baseline in HbA1c at Week 24 was greater (P < 0.0001) with Empa/Lina than with Empa/Plc (primary outcome, Empa/Lina 10/5: -0.94 vs -0.12%; adjusted mean difference, -0.82%; Empa/Lina 25/5: -0.91 vs -0.33%; adjusted mean difference, -0.59%). Over 24- and 52-week periods, higher proportions of patients achieved HbA1c < 7.0% and greater decreases in fasting plasma glucose were observed with Empa/Lina compared with Empa/Plc. Empa/Lina was well tolerated, with no unexpected adverse events or diabetic ketoacidosis. One case of confirmed hypoglycaemia with Empa/Plc 25/5 was reported. CONCLUSIONS:These results support Empa/Lina FDC as a potential option for Japanese patients with T2DM who require combination therapy. ClinicalTrials.gov NCT02489968.

Project description:BackgroundType 2 diabetes causes cardio-renal complications and is treated with different combination therapies. The renal hemodynamics profile of such combination therapies has not been evaluated in detail.MethodsPatients (N = 97) with type 2 diabetes were randomized to receive either empagliflozin and linagliptin (E+L group) or metformin and insulin glargine (M+I group) for 3 months. Renal hemodynamics were assessed with para-aminohippuric acid and inulin for renal plasma flow (RPF) and glomerular filtration rate (GFR). Intraglomerular hemodynamics were calculated according the Gomez´ model.ResultsTreatment with E+L reduced GFR (p = 0.003), but RPF remained unchanged (p = 0.536). In contrast, M+I not only reduced GFR (p = 0.001), but also resulted in a significant reduction of RPF (p < 0.001). Renal vascular resistance (RVR) decreased with E+L treatment (p = 0.001) but increased with M+I treatment (p = 0.001). The changes in RPF and RVR were different between the two groups (both padjust < 0.001). Analysis of intraglomerular hemodynamics revealed that E+L did not change resistance of afferent arteriole (RA) (p = 0.116), but diminished resistance of efferent arterioles (RE) (p = 0.001). In M+I group RA was increased (p = 0.006) and RE remained unchanged (p = 0.538). The effects on RA (padjust < 0.05) and on RE (padjust < 0.05) differed between the groups.ConclusionsIn patients with type 2 diabetes and preserved renal function treatment with M+I resulted in reduction of renal perfusion and increase in vascular resistance, in contrast to treatment with E+I that preserved renal perfusion and reduced vascular resistance. Moreover, different underlying effects on the resistance vessels have been estimated according to the Gomez model, with M+I increasing RA and E+L predominantly decreasing RE, which is in contrast to the proposed sodium-glucose cotransporter 2 inhibitor effects.Trial registrationThe study was registered at www.clinicaltrials.gov (NCT02752113) on April 26, 2016.

Project description:IntroductionThe 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.MethodsThe 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.ResultsDapagliflozin/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.ConclusionDapagliflozin/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 registrationCTRI/2022/08/044563; 01/08/2022.
