A Novel Therapeutic Agent for Type 2 Diabetes Mellitus: SGLT2 Inhibitor.

ABSTRACT: Type 2 diabetes mellitus (T2DM) is a complex endocrine and metabolic disorder, and a major public health problem that is rapidly increasing in prevalence. Although a wide range of pharmacotherapies for glycemic control is now available, management of T2DM remains complex and challenging. The kidneys contribute immensely to glucose homeostasis by reabsorbing glucose from the glomerular filtrate. Sodium-glucose cotransporter 2 (SGLT2) inhibitors, a new class of antidiabetic agents that inhibit glucose absorption from the kidney independent of insulin, offer a unique opportunity to improve the outcomes of patients with T2DM. In this review, we provide an overview of two globally-approved SGLT2 inhibitors, dapagliflozin and canagliflozin, and discuss their effects and safety. This information will help clinicians to decide whether these drugs will benefit their patients.

Project description:IntroductionThe treatment of type 2 diabetes mellitus (T2DM) continues to pose challenges for clinicians and patients. The dramatic rise in T2DM prevalence, which has paralleled the rise in obesity, has strained the healthcare system and prompted the search for therapies that not only effectively treat hyperglycemia, but are also weight neutral or promote weight loss. In most clinical situations after diagnosis, patients are advised to adopt lifestyle changes and metformin is initiated to help control blood glucose levels. However, metformin may not be tolerated, or may not be sufficient for those with higher glucose levels at diagnosis. Even among those who have initial success with metformin, the majority eventually require one or more additional agents to achieve their treatment goals. Because T2DM is a progressive disease, the requirement for combination treatment escalates over time, driving the need for therapies with complementary mechanisms of action.Methods and resultsOnline public resources were searched using "empagliflozin", identifying 32 articles in PubMed, and 12 abstracts presented at the 2013 American Diabetes Association meeting. Peer-reviewed articles and abstracts describing preclinical studies and clinical trials were retrieved, and relevant publications included in this review. Trials registered on clinicaltrials.gov were searched for ongoing empagliflozin studies.ConclusionThe sodium-glucose co-transporter 2 (SGLT2) inhibitors are of great interest since they provide a novel, insulin-independent mechanism of action. The SGLT2 inhibitor empagliflozin has demonstrated promising pharmacodynamic and pharmacokinetic properties. In clinical trials, empagliflozin has demonstrated a good efficacy and safety profile in a broad range of patients with T2DM, and appears to be an attractive adjunct therapeutic option for the treatment of T2DM. Ongoing trials, including patients with T2DM and comorbidities such as hypertension, are expected to provide important additional data, which will further define the role of empagliflozin in a growing movement toward individualized approaches to diabetes care.

Project description:BackgroundThe sodium-dependent glucose co-transporter-2 (SGLT2) is expressed in absorptive epithelia of the renal tubules. Remogliflozin etabonate (RE) is the prodrug of remogliflozin, the active entity that inhibits SGLT2. An inhibitor of this pathway would enhance urinary glucose excretion (UGE), and potentially improve plasma glucose concentrations in diabetic patients. RE is intended for use for the treatment of type 2 diabetes mellitus (T2DM) as monotherapy and in combination with existing therapies. Metformin, a dimethylbiguanide, is an effective oral antihyperglycemic agent widely used for the treatment of T2DM.MethodsThis was a randomized, open-label, repeat-dose, two-sequence, cross-over study in 13 subjects with T2DM. Subjects were randomized to one of two treatment sequences in which they received either metformin alone, RE alone, or both over three, 3-day treatment periods separated by two non-treatment intervals of variable duration. On the evening before each treatment period, subjects were admitted and confined to the clinical site for the duration of the 3-day treatment period. Pharmacokinetic, pharmacodynamic (urine glucose and fasting plasma glucose), and safety (adverse events, vital signs, ECG, clinical laboratory parameters including lactic acid) assessments were performed at check-in and throughout the treatment periods. Pharmacokinetic sampling occurred on Day 3 of each treatment period.ResultsThis study demonstrated the lack of effect of RE on steady state metformin pharmacokinetics. Metformin did not affect the AUC of RE, remogliflozin, or its active metabolite, GSK279782, although Cmax values were slightly lower for remogliflozin and its metabolite after co-administration with metformin compared with administration of RE alone. Metformin did not alter the pharmacodynamic effects (UGE) of RE. Concomitant administration of metformin and RE was well tolerated with minimal hypoglycemia, no serious adverse events, and no increase in lactic acid.ConclusionsCoadministration of metformin and RE was well tolerated in this study. The results support continued development of RE as a treatment for T2DM.Trial registrationClinicalTrials.gov, NCT00376038.

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.
