Sodium-glucose co-transporter 2 (SGLT2) inhibitors: a growing class of antidiabetic agents.

ABSTRACT: Although several treatment options are available to reduce hyperglycemia, only about half of individuals with diagnosed diabetes mellitus (DM) achieve recommended glycemic targets. New agents that reduce blood glucose concentrations by novel mechanisms and have acceptable safety profiles are needed to improve glycemic control and reduce the complications associated with type 2 diabetes mellitus (T2DM). The renal sodium-glucose co-transporter 2 (SGLT2) is responsible for reabsorption of most of the glucose filtered by the kidney. Inhibitors of SGLT2 lower blood glucose independent of the secretion and action of insulin by inhibiting renal reabsorption of glucose, thereby promoting the increased urinary excretion of excess glucose. Canagliflozin, dapagliflozin, and empagliflozin are SGLT2 inhibitors approved as treatments for T2DM in the United States, Europe, and other countries. Canagliflozin, dapagliflozin, and empagliflozin increase renal excretion of glucose and improve glycemic parameters in patients with T2DM when used as monotherapy or in combination with other antihyperglycemic agents. Treatment with SGLT2 inhibitors is associated with weight reduction, lowered blood pressure, and a low intrinsic propensity to cause hypoglycemia. Overall, canagliflozin, dapagliflozin, and empagliflozin are well tolerated. Cases of genital infections and, in some studies, urinary tract infections have been more frequent in canagliflozin-, dapagliflozin-, and empagliflozin-treated patients compared with those receiving placebo. Evidence from clinical trials suggests that SGLT2 inhibitors are a promising new treatment option for T2DM.

Project description:Sodium-glucose co-transporter-2 (SGLT2) inhibitors (gliflozins) are the newest class of medication available to treat type 2 diabetes (T2DM). Recent findings from the first complete cardiovascular safety trial in SGLT2 inhibitors, the Empagliflozin, Cardiovascular Outcomes, and Mortality in type 2 diabetes (EMPA-REG OUTCOMES) trial, demonstrated reduced cardiovascular outcomes in people with high cardiovascular risk. How to apply these findings to clinical practice remains unclear, with questions remaining on who will reap this cardiovascular benefit.To describe the proportion of people in the real world currently treated with SGLT2 inhibitors who meet the inclusion criteria of the EMPA-REG trial and therefore could expect the cardiovascular benefit identified by the trial. Similarly, to describe the proportion of people from the whole T2DM population who could also expect this same benefit.Routinely collected data from UK primary care in the Royal College of General Practitioners (RCGP) Research and Surveillance Centre (RSC) database will be used. The study population will include all people with T2DM within this database (approximately 60,000). We will perform a cross-sectional investigation to describe the characteristics of people currently using SGTL2 inhibitors compared with the population of the EMPA-REG trail. We will similarly compare the characteristics of the RCGP RSC T2DM cohort with the inclusion criteria of the EMPA-REG trial.People with T2DM using a pre-existing verified clinical ontological process will be identified, as will people with prescriptions for SGLT2 inhibitors and other medications using Read coded and other proprietary coding systems. Descriptive statistics will be used to characterise the key clinical characteristics of people with T2DM using SGLT2 inhibitors and to compare these characteristics to people included in EMPA-REG trial; the proportion of people who match the trial criteria will be reported.Peer review publication reporting the real world lessons for clinical practice.AstraZeneca.

Project description:ObjectiveTo estimate the association between the use of sodium glucose co-transporter-2 (SGLT2) inhibitors and postmarket harms as identified by drug regulatory agencies.DesignWe conducted a systematic review and meta-analysis of randomised controlled trials (RCT). Six large databases were searched from inception to May 2018. Random effects models were used to estimate pooled relative risks (RRs).InterventionSGLT2 inhibitors, compared with placebo or active comparators.Primary outcomesAcute kidney injury (AKI), diabetic ketoacidosis (DKA), urinary tract infections (UTI), bone fractures and lower limb amputations.ResultsWe screened 2418 citations of which 109 were included. Most studies included one of four SGLT2 inhibitors, dapagliflozin, canagliflozin, empagliflozin and ipragliflozin. When compared with placebo, SGLT2 inhibitors were found to be significantly protective against AKI (RR=0.59; 95% CI 0.39 to 0.89; I2=0.0%), while no difference was found for DKA (RR 0.66; 95% CI 0.30 to 1.45, I2=0.0%), UTI (RR 1.02; 95% CI 0.95 to 1.09, I2=0.0%) or bone fracture (RR 0.87; 95% CI 0.69 to 1.09, I2=1.3%). Three studies reported on amputation, with one finding a significant increase risk. No increased risk for either outcome was found when compared with active controls. Subgroup analysis did show an increased risk of UTI with dapagliflozin only (RR 1.21; 95% CI 1.02 to 1.43, I2=0.0%), but no other analysis supported an increased risk of AKI, DKA, UTI or fracture.ConclusionsCurrent evidence from RCTs does not suggest an increased risk of harm with SGLT2 inhibitors as a class over placebo or active comparators with respect to AKI, DKA, UTI or fracture. However, wide CIs for many comparisons suggest limited precision, and therefore clinically important adverse events cannot be ruled out. Dapagliflozin, appears to independently increase the risk of UTI, although the mechanism for this intraclass variation in risk is unclear.Prospero registration numberCRD42016038715.
