Dapagliflozin in patients with type 2 diabetes mellitus.

ABSTRACT: Dapagliflozin is a selective and reversible inhibitor of sodium-glucose linked transporter type 2 (SGLT2), which mediates approximately 90% of active renal glucose reabsorption in the early proximal tubule of the kidney. Dapagliflozin significantly reduces glucose reabsorption and decreases serum glucose concentration in an insulin-independent manner. The decrease of glucose reabsorption by dapagliflozin has also been associated with a reduction in body weight. Furthermore, the drug modestly reduces blood pressure levels through weight loss and its action as osmotic diuretic. Dapagliflozin has been approved as monotherapy in patients with type 2 diabetes mellitus (T2DM) who cannot tolerate metformin or in combination with other antidiabetic drugs, with the exception of pioglitazone due to the theoretical increased risk of bladder cancer. The drug should not be prescribed in patients with moderate or severe renal impairment or in patients at risk for developing volume depletion. Dapagliflozin is associated with increased incidence of genital and lower urinary tract infections, but these infections are usually mild to moderate and respond to standard antimicrobial treatment. Based on current evidence, dapagliflozin is a useful drug for patients with T2DM with a favorable safety profile. However, further research regarding the effects of dapagliflozin on cardiovascular outcomes is needed.

Project description:IntroductionSodium-glucose co-transporter-2 (SGLT2) inhibitors moderately reduce glucose levels in type-2 diabetes mellitus (T2DM). Some cases of diabetic ketoacidosis (DKA) were reported with SGLT2 inhibitors. However, data on the long-term safety of dapagliflozin in Saudi Arabia are lacking. The present study aimed to monitor the safety of dapagliflozin in patients with T2DM and evaluate the change in HbA1c during the observation period compared to baseline.MethodsThis was a local, prospective, single-arm, non-interventional, regulatory post-marketing study. The study was conducted in Saudi Arabia from May 2017 to September 2019. Patients received either 5 or 10 mg dapagliflozin in conjunction with diet and exercise modifications to treat T2DM. The occurrence of adverse events was observed over the treatment duration and for 3 days after administering the last dose of dapagliflozin.ResultsA total of 527 patients were recruited in the study, 524 of which were eligible for the statistical analysis. About 62% were males. The median (IQR) age was 52.3 (14.8) years, while the median (IQR) body mass index was 31.6 (7.7) kg/m2. The median (IQR) duration since the patients were first diagnosed with T2DM was 8.78 (6.73) years. The most common comorbidities were hyperlipidemia (51.1%) and hypertension (41.1%). Almost three-quarters of the study population (73.7%) received other antidiabetic medications in addition to dapagliflozin. Over a period of 12 months, a total of 106 adverse events were experienced by 65 (12.33%) patients. Vulvovaginal pruritus (3.1%), dysuria (2.7%), polyuria (1.3%), urinary tract infections (1%), fatigue (0.8%), and hypoglycemia (0.8%) were among the reported adverse events. One case of DKA (0.2%) was reported. The mean (SD) HbA1c% level significantly decreased from 8.6 (1.6) % at baseline to reach 7.2 (1.2) % after 12 months of treatment (p < 0.0001).ConclusionDapagliflozin was found to be a well tolerated and effective treatment option for T2DM patients in Saudi Arabia. Vulvovaginal pruritus and dysuria were the most common adverse events.

Project description:IntroductionHyperkalemia risk is increased in diabetes, particularly in patients with renal impairment or those receiving angiotensin-converting enzyme (ACE) inhibitors, angiotensin receptor blockers (ARBs) or potassium-sparing diuretics. Conversely, other diuretics can increase hypokalemia risk. We assessed the effects of the sodium glucose co-transporter 2 (SGLT2) inhibitor dapagliflozin on serum potassium levels in a pooled analysis of clinical trials in patients with type 2 diabetes mellitus (T2DM).MethodsFourteen randomized, placebo-controlled, double-blind T2DM studies were analyzed: pooled data from 13 studies of ≤24 weeks' duration (dapagliflozin 10 mg, N = 2360; placebo, N = 2295); and one 52-week moderate renal impairment study in patients with baseline eGFR ≥30 to <60 mL/min/1.73 m(2) (dapagliflozin 10 mg, N = 85; placebo, N = 84). Central laboratory serum potassium levels were determined at each study visit.ResultsNo clinically relevant mean changes from baseline in serum potassium ≤24 weeks were reported for dapagliflozin 10 mg [-0.05 mmol/L; 95% confidence interval (CI) -0.07, -0.03] versus placebo (-0.02 mmol/L; 95% CI -0.04, 0.00) in the pooled population or in the renal impairment study (-0.03 mmol/L; 95% CI -0.14, 0.08 vs. -0.02 mmol/L; 95% CI -0.13, 0.09, respectively). The incidence rate ratio for serum potassium ≥5.5 mmol/L over 24 weeks for dapagliflozin 10 mg versus placebo was 0.90 (95% CI 0.74, 1.10) in the pooled population; with no increased risk in patients receiving ARBs/ACE inhibitors, or potassium-sparing diuretics, or in those with moderate renal impairment. Slightly more patients receiving dapagliflozin 10 mg had serum potassium ≤3.5 mmol/L versus placebo (5.2% vs. 3.6%); however, no instances of serum potassium ≤2.5 mmol/L were reported.ConclusionDapagliflozin is not associated with an increased risk of hyperkalemia or severe hypokalemia in patients with T2DM.FundingBristol-Myers Squibb and AstraZeneca.

Project description:BackgroundThe benefits of sodium glucose cotransporters 2 (SGLT2) inhibitors in patients with type 2 diabetes mellitus include plasma glucose control, reduction in body weight and blood pressure, and low risk of hypoglycemia, although they may also cause genitourinary infections, polyuria, or volume depletion. It is not clear whether dapagliflozin, an SGLT2 inhibitor, improves treatment satisfaction among patients in a comprehensive way despite the negative side effects. This study assessed the effect of dapagliflozin on glycosylated hemoglobin (HbA1c), body weight, and treatment satisfaction in overweight patients with type 2 diabetes mellitus treated with oral hypoglycemic agents.MethodsThis multicenter, open-label, single-arm observational study included patients with type 2 diabetes mellitus administering dapagliflozin 5 or 10 mg per day for 14 weeks. Changes in treatment satisfaction were evaluated using a new version of the Oral Hypoglycemic Agent-Questionnaire (OHA-Q ver. 2) consisting of 23 items. Correlation between treatment satisfaction and HbA1c levels and body weight were analyzed using the Spearman's rank-correlation coefficient.ResultsOf the 221 patients enrolled, 188 completed the study. Mean HbA1c decreased from 7.8 ± 0.7% (62.1 ± 7.5 mmol/mol) to 7.3 ± 0.8% (55.9 ± 8.7 mmol/mol) (change - 0.6 ± 0.7%, P < 0.001) and body weight decreased from 82.5 ± 14.6 to 80.7 ± 14.8 kg (change - 2.3 ± 2.8 kg, P < 0.001). OHA-Q ver. 2 was validated as well, the mean OHA-Q ver. 2 total score increased from 44.3 ± 9.4 to 46.6 ± 9.8 (best score 69, worst score 0; change 2.3 ± 6.6, P < 0.001). The change in body weight significantly correlated with the OHA-Q ver. 2 total score (Spearman's ρ = - 0.17, P = 0.035). The change in HbA1c levels significantly correlated with the satisfaction subscale score (Spearman's ρ = - 0.19, P = 0.011).ConclusionsDapagliflozin significantly improved treatment satisfaction among patients with type 2 diabetes mellitus for 14 weeks. Body weight loss significantly correlated with treatment satisfaction.Trial registration UMIN-CTR: UMIN000016304.

Project description:IntroductionTo date there is a lack of economic analysis comparing glucagon-like peptide-1 receptor agonists (GLP-1RAs) to sodium-glucose co-transporter 2 inhibitors (SGLT-2i) for the treatment of type 2 diabetes mellitus (T2DM). Liraglutide and dapagliflozin are the most commonly prescribed GLP-1RA and SGLT-2i in the UK. This analysis investigated the cost-effectiveness of liraglutide 1.2 and 1.8 mg/day compared to dapagliflozin 10 mg/day for the treatment of T2DM in the UK in patients on dual and triple antidiabetic therapy.MethodsCost-effectiveness analysis was conducted in the QuintilesIMS CORE Diabetes Model (CDM). The model estimated expected costs and outcomes over a lifetime horizon using the UK national payer perspective. Liraglutide efficacy estimates and patient characteristics were sourced from a trial in patients on prior metformin monotherapy, and from a trial in patients on prior combination therapy. Comparative efficacy data for the other interventions were derived from a network meta-analysis. Utility inputs were extracted from a systematic literature review. Costs are presented in Great British Pound (GBP), 2016 values.ResultsIn dual and triple therapy, liraglutide 1.2 mg was less costly and more effective compared with dapagliflozin 10 mg, providing a QALY gain of 0.04 and cost savings of GBP 11 per patient in dual therapy, and a QALY gain of 0.06 and cost savings of GBP 71 per patient in triple therapy. For liraglutide 1.8 mg, increased efficacy and costs compared with dapagliflozin 10 mg were observed in both dual and triple therapy. In dual therapy, a QALY gain of 0.07 and additional costs of GBP 888 per patient yielded an ICER of GBP 13,227, whereas in triple therapy a QALY gain of 0.07 and additional cost of GBP 791 per patient gave an ICER of 11,857.ConclusionThis long-term modelling analysis found that both dosages of liraglutide may be cost-effective treatment alternatives as part of a dual or a triple antidiabetic therapy in patients for whom an SGLT-2i therapy is considered.FundingNovo Nordisk.
