Update on long-term efficacy and safety of dapagliflozin in patients with type 2 diabetes mellitus.

ABSTRACT: Sodium-glucose cotransporter 2 (SGLT2) inhibitors are a novel class of antihyperglycaemic agents with an insulin-independent mode of action. Dapagliflozin is a member of the SGLT2 inhibitors class that has received marketing authorization in Europe and the US for use in patients with type 2 diabetes. This review summarizes current evidence from clinical trials assessing the clinical efficacy and safety of dapagliflozin, and presents data regarding its cost-effectiveness. Treatment with dapagliflozin results in similar reduction in haemoglobin A1c with other oral antihyperglycaemic drugs, which is preserved over 4 years of treatment. However, compared with most antidiabetic agents, dapagliflozin provides additional clinical benefits including body weight loss and blood pressure reduction. Moreover, treatment with dapagliflozin does not increase risk for hypoglycaemia, but is associated with increased incidence of mild to moderate urinary and genital tract infections. A pivotal outcomes trial of dapagliflozin is expected to clarify its effect on cardiovascular endpoints, whilst a causative relationship between dapagliflozin and select malignancies is unlikely. Finally, based on recent economic evaluations dapagliflozin seems to be a cost-effective option for type 2 diabetes in some settings.

Project description:ObjectiveTo evaluate the 104-week safety of dapagliflozin in older patients with type 2 diabetes mellitus.MethodsPooled analysis assessing general safety (nine phase III studies ≤104 weeks) and cardiovascular safety (21 phase IIb/III studies ≤208 weeks) by age (<65; ≥65; ≥75 years). Patients with type 2 diabetes mellitus (±background glucose-lowering therapy) received: dapagliflozin 10 mg (n = 2026) vs. placebo (n = 1956) (nine-study pool); or dapagliflozin (2.5-50 mg; n = 5936) vs. control (placebo/comparator) (n = 3403) (21-study pool).ResultsAdverse events (AEs) and discontinuations owing to AEs were more common in older vs. younger patients, and were more frequent with dapagliflozin than placebo (AEs: <65 years: 73.1 vs. 70.7 %; ≥65 years: 77.4 vs. 73.1 %; ≥75 years: 80.4 vs. 75.3 %, respectively; discontinuations: <65 years: 5.9 vs. 5.0 %; ≥65 years: 14.4 vs. 12.2 %; ≥75 years: 26.8 vs. 22.1 %, respectively); serious AE (SAE) frequency was similar (<65 years: 11.0 vs. 11.8 %; ≥65 years: 20.0 vs. 20.2 %; ≥75 years: 19.6 vs. 18.2 %, respectively). Hypoglycaemia frequency was similar across age groups and was higher with dapagliflozin than placebo (<65 years: 18.0 vs. 13.4 %; ≥65 years: 20.2 vs. 17.7 %; ≥75 years: 17.5 vs. 16.9 %, respectively); major episodes were rare. Urinary tract infection frequency was similar between treatment groups in older patients, with no increase vs. younger patients (<65 years: 8.8 vs. 5.5 %; ≥65 years: 8.1 vs. 7.6 %; ≥75 years: 8.2 vs. 9.1 %, respectively); urinary tract infection SAEs were rare. Genital infection AEs were more common with dapagliflozin, with no increase in older patients (<65 years: 8.2 vs. 1.0 %; ≥65 years: 6.6 vs. 0.9 %; ≥75 years: 7.2 vs. 0.0 %, respectively) and no SAEs. Volume reduction AEs were uncommon, with a higher frequency with dapagliflozin vs. placebo and in patients ≥75 years (<65 years: 1.7 vs. 1.2 %; ≥65 years: 2.3 vs. 1.7 %; ≥75 years: 3.1 vs. 2.6 %, respectively). Dapagliflozin did not increase the risk of fractures (<65 years: 1.1 vs. 1.1 %; ≥65 years: 1.1 vs. 2.7 %; ≥75 years: 1.0 vs. 2.6 %, respectively) or falls (<65 years: 0.7 vs. 0.7 %; ≥65 years: 0.6 vs. 2.1 %; ≥75 years: 0.0 vs. 1.3 %, respectively), regardless of age. AEs of renal function were more common with dapagliflozin than placebo and increased with age (<65 years: 3.5 vs. 2.3 %; ≥65 years: 14.0 vs. 7.9 %; ≥75 years: 29.9 vs. 20.8 %, respectively). Most were non-serious small transient increases in serum creatinine. Dapagliflozin did not increase cardiovascular risk regardless of age [hazard ratio (95 % confidence interval) vs.Control<65 years: 0.726 (0.473, 1.114); ≥65 years: 0.879 (0.565, 1.366); ≥75 years: 0.950 (0.345, 2.617), respectively].ConclusionDapagliflozin treatment up to 104 weeks was well tolerated in older patients. Older dapagliflozin-treated patients had more renal AEs than placebo-treated patients; the majority of which were non-serious small transient changes in serum creatinine.

Project description:BACKGROUND:Dapagliflozin, a novel inhibitor of sodium-glucose cotransporter-2 (SGLT-2), lowers blood glucose level by specifically inhibiting the activity of SGLT-2. Previous studies showed efficacy and safety of dapagliflozin combined with other antihyperglycemic agents in type 2 diabetes (T2DM), however, there are few studies for dapagliflozin as monotherapy. The aim of this study was to assess the efficacy and safety of dapagliflozin as a monotherapy in T2DM and provide theoretical basis for clinical rational use of drugs. METHODS:We did a systematic review and meta-analysis of randomized, placbo-controlled clinical studies in patients with type 2 diabetes. We searched PubMed, Embase, Cochrane Library, CNKI, Wanfang, and VIP database through October 2018, we also manually screened list of references to the previous meta-analysis of dapagliflozin in the treatment of type 2 diabetes. Data search and extraction were completed with a standardized data form and any discrepancies were resolved by consensus. A meta-analysis was conducted by using RevMan 5.3 software. RESULTS:Six randomized controlled trials (RCTs) including 2033 patients were analyzed. Compared with placebo, dapagliflozin monotherapy was associated with a reduction in glycosylated hemoglobin A1c (HbA1c) (weighted mean difference [WMD]: -0.60%; 95% confidence interval [CI]: -0.67%, -0.52%; P < .00001), fasting plasam glucose (FPG) (WMD: -1.30 mmol/L; 95% CI: -1.52, -1.08; P < .00001), and body weight (WMD: -1.50 kg; 95% CI: -1.67, -1.32; P < .00001). Dapagliflozin was associated with an increased risk of urinary tract infections (relative risk [RR]: 1.74; 95% CI: 1.21, 2.49; P = .003) and genital tract infections (RR: 3.52; 95% CI: 2.06, 6.03; P < .00001). CONCLUSIONS:Dapagliflozin monotherapy was well tolerated and effective in reducing the level of HbA1c, FPG, and body weight in patients with T2DM without increasing hypoglycaemia, although it may increase the risk of urinary tract infections and genital tract infections. This meta-analysis provides an evidence for the treatment in patients with T2DM. However, more randomized clinical evidences are still needed to verify the results.

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.
