Hemodynamic effects of the dipeptidyl peptidase-4 inhibitor linagliptin with renin-angiotensin system inhibitors in type 2 diabetic patients with albuminuria

Objective: Concomitant treatment with angiotensin-converting enzyme (ACE) inhibitors and dipeptidyl peptidase-4 (DPP-4) inhibitors is increasingly common. Pharmacological studies have suggested a potential adverse drug interaction between ACE inhibitors and DPP-4 inhibitors resulting in unfavorable hemodynamic changes; very few studies have examined such an interaction between angiotensin II receptor blockers (ARBs) and DPP-4 inhibitors. We investigated blood pressure (BP) and heart rate (HR) during treatment with the DPP-4 inhibitor linagliptin in individuals receiving either ACE inhibitors or ARBs in the MARLINA-T2D trial. Methods: In this study, 360 individuals with type 2 diabetes and albuminuria receiving unchanged doses of ACE inhibitors or ARBs were randomized to linagliptin or placebo. Twenty-four-hour ambulatory BP monitoring, an exploratory endpoint, was conducted at baseline and after 24 weeks. Results: Ambulatory BP monitoring data were available for 208 individuals (linagliptin: n = 111; placebo: n = 97). Baseline mean +/- SD 24-h SBP and DBP were 132.5 +/- 12.4 mmHg and 75.9 +/- 9.4 mmHg, respectively; mean 24-h HR was 76.3 +/- 10.1 bpm. At week 24, no overall effect of the DPP-4 inhibitor versus placebo was seen on mean 24-h SBP, DBP, or HR. Furthermore, in the subgroups receiving either an ACE inhibitor or an ARB, no effect on these hemodynamic parameters was seen as a result of concomitant DPP-4 inhibitor treatment. Conclusion: Adding linagliptin to treatment with ACE inhibitors or ARBs was not associated with any hemodynamic changes, supporting their concomitant use in individuals with type 2 diabetes and albuminuria.Peer reviewe

Empagliflozin in women with type 2 diabetes and cardiovascular disease - an analysis of EMPA-REG OUTCOMEA (R)

Aims/hypothesis The global epidemic of type 2 diabetes affects women and men equally; however, the relative impact on the cardiovascular (CV) system appears greater for women than men when compared with peers without diabetes. Furthermore, women are often under-represented in CV outcome trials, resulting in less certainty about the impact of CV prevention therapies across the sexes. The EMPA-REG OUTCOME® trial, which included 28.5% women, found that empagliflozin, given in addition to standard of care, reduced the risk of CV death by 38%, heart failure (HF) hospitalisation by 35% and a composite endpoint for incident or worsening nephropathy by 39%. Here we report a secondary analysis of the trial to determine the relative effects of empagliflozin in women vs men. Methods The population studied were individuals with type 2 diabetes (HbA1c 53–86 mmol/mol [7–10%] and eGFR >30 ml min−1 [1.73 m]−2 ), with established atherosclerotic CV disease. Individuals were randomised to receive empagliflozin 10 mg or 25 mg, or placebo once daily in addition to standard of care, and followed. The trial continued until ≥691 individuals had experienced an adjudicated event included in the primary outcome. All CV outcome events, including HF hospitalisations and deaths were prospectively adjudicated by blinded clinical events committees. Results At baseline, the demographic profile of the 2004 women (age ± standard deviation 63.6 ± 8.8 years) compared with the 5016 men (age 63.0 ± 8.6 years) in the trial was largely similar, with the exception that LDL-cholesterol was numerically higher in women (2.5 ± 1.0 vs 2.1 ± 0.9 mmol/l), consistent with lower rates of lipid-lowering therapies (75.4% vs 83.2%). Women were also less likely to have smoked (31.5% vs 69.9%). The annualised incidence rate for women in the placebo group was numerically lower than in men for CV death (1.58% vs 2.19%), numerically higher for HF hospitalisation (1.75% vs 1.33%) and similar for renal events (7.22% vs 7.75%). We did not detect any effect modification by sex within the statistical power restrictions of the analysis for CV death, HF hospitalisation and incident or worsening nephropathy (interaction p values 0.32, 0.20 and 0.85, respectively). Compared with placebo, empagliflozin increased the rates of genital infections in both women (2.5% vs 10.0%) and men (1.5% vs 2.6%). Conclusions/interpretation CV death, HF hospitalisation and incident or worsening nephropathy rate reductions induced by empagliflozin were not different between women and men.status: publishe

Risk of hypoglycaemia in people aged ≥65 years receiving linagliptin: pooled data from 1489 individuals with type 2 diabetes mellitus

Aims: To investigate the risk of hypoglycaemia in people aged ≥65 years with type 2 diabetes mellitus (T2DM) treated with linagliptin, in the largest pooled analysis performed to date. Materials and methods: One thousand four hundred and eighty-nine patients aged ≥65 years with T2DM were pooled from 11 randomised, double-blind, parallel group, placebo-controlled trials evaluating linagliptin 5 mg alone, or in addition to various background therapies. The primary safety endpoint was the incidence of investigator-defined hypoglycaemia. Results: There was no significant difference in the risk of hypoglycaemia between linagliptin and placebo in the all-patient population at 24 weeks (hazard ratio [HR] 1.07; 95% confidence interval [CI]: 0.84, 1.36; P = 0.5943)—despite significant (P < 0.0001) improvements in glycaemic control—and 1 year (HR 1.02; 95% CI: 0.81, 1.27; P = 0.8803). Similar findings were observed for linagliptin vs placebo in subgroup analyses by background medication (eg, sulphonylureas (SUs) and/or insulin vs no such drugs), age, baseline glycated haemoglobin (HbA1c), ethnicity, and baseline estimated glomerular filtration rate. Patients with a baseline HbA1c ≥7.5% had significantly higher odds of achieving HbA1c <7.5% without hypoglycaemia in the linagliptin group compared with placebo at 24 weeks (34.1% vs 13.7%; 95% CI: 2.04, 4.12; P < 0.0001). Conclusions: This pooled analysis indicates that linagliptin was effective in treating older people with T2DM towards their HbA1c targets with a favourable safety and tolerability profile and low risk of hypoglycaemia. The safety profile was maintained even on background therapies with known risk of hypoglycaemia, such as insulin and SU
