Glucagon secretion and its association with glycaemic control and ketogenesis during sodium-glucose cotransporter 2 inhibition by ipragliflozin in people with type 1 diabetes: Results from the multicentre, open-label, prospective study. Diabetes Obes Metab 2024; 26:1605-1614. [PMID: 38253809 DOI: 10.1111/dom.15458] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/24/2023] [Revised: 12/27/2023] [Accepted: 01/04/2024] [Indexed: 01/24/2024]
Abstract
AIM Clinical trials showed the efficacy of sodium-glucose cotransporter 2 inhibitors for type 1 diabetes (T1D) by significant reductions in body weight and glycaemic variability, but elevated susceptibility to ketoacidosis via elevated glucagon secretion was a potential concern. The Suglat-AID evaluated glucagon responses and its associations with glycaemic control and ketogenesis before and after T1D treatment with the sodium-glucose cotransporter 2 inhibitor, ipragliflozin. METHODS Adults with T1D (n = 25) took 50-mg open-labelled ipragliflozin daily as adjunctive to insulin. Laboratory/clinical data including continuous glucose monitoring were collected until 12 weeks after the ipragliflozin initiation. The participants underwent a mixed-meal tolerance test (MMTT) twice [before (first MMTT) and 12 weeks after ipragliflozin treatment (second MMTT)] to evaluate responses of glucose, C-peptide, glucagon and β-hydroxybutyrate. RESULTS The area under the curve from fasting (0 min) to 120 min (AUC0-120min) of glucagon in second MMTT were significantly increased by 14% versus first MMTT. The fasting and postprandial β-hydroxybutyrate levels were significantly elevated in second MMTT versus first MMTT. The positive correlation between postprandial glucagon secretion and glucose excursions observed in first MMTT disappeared in second MMTT, but a negative correlation between fasting glucagon and time below range (glucose, <3.9 mmol/L) appeared in second MMTT. The percentage changes in glucagon levels (fasting and AUC0-120min) from baseline to 12 weeks were significantly correlated with those in β-hydroxybutyrate levels. CONCLUSIONS Ipragliflozin treatment for T1D increased postprandial glucagon secretion, which did not exacerbate postprandial hyperglycaemia but might protect against hypoglycaemia, leading to reduced glycaemic variability. The increased glucagon secretion might accelerate ketogenesis when adequate insulin is not supplied.

Abstract
AIMS Sodium glucose cotransporter2 (SGLT2) inhibitors are controversial in the treatment of type 1 diabetes mellitus (T1DM). This study is a systematic evaluation of the safety of SGLT2 inhibitors usage in T1DM. METHODS Comprehensive literature search in six databases from inception to September 2022. Randomized controlled trials (RCTs) of T1DM treated with SGLT2 inhibitor vs. placebo were included. Data were extracted from the literature that met the inclusion criteria. After quality evaluation by the Cochrane risk bias assessment tool, meta-analysis was performed using Revman 5.4 and Stata 17.1. RESULTS The study consisted of 16 RCTs with 7192 patients. The results indicated that SGLT2inhibitors reduce glycated hemoglobin (HbA1c, Mean difference (MD)- 0.29%, P < 0.05), fasting plasma glucose (FPG, MD-0.85 mmol/L, P < 0.05), mean amplitude of glucose excursions (MAGE, 15.75 mg/dL, P < 0.05), body weight (MD-3.49 kg, P < 0.05), and total insulin dosage (MD-7.14 IU/day, P < 0.05). Furthermore, cautious SGLT2 inhibitors did not induce the risk of hypoglycemia (RR1.00, P = 0.86), urinary tract infections (RR1.02, P = 0.085), and diarrhea (RR1.34, P = 0.523). CONCLUSION Based on this meta-analysis, SGLT22 inhibitors reduce insulin dosage without increasing the risk of hypoglycemia and diabetic ketoacidosis for type 1 diabetes mellitus in 1month.

[PMID: 37819017 PMCID: PMC10730240 DOI: 10.1093/cvr/cvad157] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/28/2023] [Revised: 07/07/2023] [Accepted: 07/27/2023] [Indexed: 10/13/2023] Open
Abstract
AIMS Empagliflozin (EMPA), a potent inhibitor of the renal sodium-glucose cotransporter 2 and an effective treatment for Type 2 diabetes, has been shown to have cardioprotective effects, independent of improved glycaemic control. Several non-canonical mechanisms have been proposed to explain these cardiac effects, including increasing circulating ketone supply to the heart. This study aims to test whether EMPA directly alters cardiac ketone metabolism independent of supply. METHODS AND RESULTS The direct effects of EMPA on cardiac function and metabolomics were investigated in Langendorff rat heart perfused with buffer containing 5 mM glucose, 4 mM β-hydroxybutyrate (βHb) and 0.4 mM intralipid, subject to low flow ischaemia/reperfusion. Cardiac energetics were monitored in situ using 31P NMR spectroscopy. Steady-state 13C labelling was performed by switching 12C substrates for 13C1 glucose or 13C4 βHb and 13C incorporation into metabolites determined using 2D 1H-13C HSQC NMR spectroscopy. EMPA treatment improved left ventricular-developed pressure during ischaemia and reperfusion compared to vehicle-treated hearts. In EMPA-treated hearts, total adenosine triphosphate (ATP) and phosphocreatine (PCr) levels, and Gibbs free energy for ATP hydrolysis were significantly higher during ischaemia and reperfusion. EMPA treatment did not alter the incorporation of 13C from glucose into glycolytic products lactate or alanine neither during ischaemia nor reperfusion. In ischaemia, EMPA led to a decrease in 13C1 glucose incorporation and a concurrent increase in 13C4 βHb incorporation into tricarboxylic acid (TCA) cycle intermediates succinate, citrate, and glutamate. During reperfusion, the concentration of metabolites originating from 13C1 glucose was similar to vehicle but those originating from 13C4 βHb remained elevated in EMPA-treated hearts. CONCLUSION Our findings indicate that EMPA causes a switch in metabolism away from glucose oxidation towards increased ketone utilization in the rat heart, thereby improving function and energetics both during ischaemia and recovery during reperfusion. This preference of ketone utilization over glucose was observed under conditions of constant supply of substrate, suggesting that EMPA acts directly by modulating cardiac substrate preference, independent of substrate availability. The mechanisms underlying our findings are currently unknown, warranting further study.

Abstract
SGLT2i (sodium glucose transporter type 2 inhibitors) are pharmacological agents that act by inhibiting the SGLT2, by reducing the renal plasma glucose threshold and inducing glycosuria, resulting in a blood glucose lowering effect. In recent years, studies demonstrating some additional positive effects of SGLT2i also in the treatment of T1D have increased progressively. The SGLT2i dapagliflozin and sotagliflozin have been temporarily licensed for use by the European Medical Agency (EMA) as an adjunct to insulin therapy in adults with T1D with a body mass index of 27 kg/m2 or higher. However, in the meantime, the US Food and Drug Administration (FDA) Endocrinologic and Metabolic Drugs Advisory Committee was divided, citing concerns about the main side effects of SGLT2i, especially diabetic ketoacidosis (DKA). The aim of this manuscript was to conduct an update on current evidence and recommendations of the reported use of SGLT2i in the treatment of T1D in humans. Preclinical studies, clinical trial and real world data suggest benefits in glycaemia control and nefro-cardiovascular protection, even though several studies have documented an important increase in the risk of DKA, a serious and life-threatening adverse event of these agents. SGLT2i potentially addresses some of the unmet needs associated with T1D by improving glycaemic control with weight loss and without increasing hypoglycemia, by reducing glycaemic variability. However, due to side effects, EMA recommendation for SGLT2 use on T1D was withdrawn. Further studies will be needed to determine the safety of this therapy in T1D and to define the type of patient who can benefit most from these medications.

Abstract
Background The treatment duration of insulin-sodium-glucose co-transporter inhibitors (SGLTis) co-treatment of type 1 diabetes mellitus (T1DM) patients in randomized controlled trials (RCTs) varies by 1-52 weeks. Henceforth, treatment duration-wise, we compared the following insulin-treatment adjuncts- mega- versus low-dose SGLTis, SGLTis versus placebo, and different SGLTi dosages. Method Double-blinded RCTs reporting the above were searched (using terms like insulin-dependent, "juvenile-onset diabetes," and "sodium glucose cotransport*") in the PubMed, Embase, and Scopus databases and appraised using a Cochrane tool. The risks across different SGLTi-dosages were compared using network meta-analysis. Random-effect pairwise meta-analysis was performed for the remaining harm juxtapositions. Meta-analyses were performed for the following treatment durations- < 4 weeks, 4 to < 24 weeks, and ≥ 24 weeks. For meta-analysis and certainty of evidence assessment, we used the Stata statistical software and the GRADE method, respectively. Results A total of 15 (low risks of bias) studies sourcing data from about 7,330 T1DM patients were reviewed. Meta-analysis findings of ≥ 24 weeks long trials were- a. SGLTi-insulin co-treatment increased the genital infection (GI) (RR: 3.51; 95% CI: 2.59, 4.77), diabetic ketoacidosis (DKA) and (RR: 3.25; 95% CI:1.29, 8.16), and serious side effects (RR: 1.43; 95% CI: 1.05, 1.94) risk. b. SGLT2i-insulin increased the GI risk (RR: 3.77; 95% CI: 2.31, 6.16; high-quality evidence). c. Sotagliflozin-insulin increased the GI (RR: 3.36; 95% CI: 2.28, 4.96) and DKA (RR: 6.69; 95% CI: 2.75, 16.32) risk (both high-quality evidence). Compared to low-dose, megadose SGLTi treatment for 4 to < 24 weeks increased the GI risk. The remaining analyses were not statistically significantly different. Conclusion On moderate to long-term treatment (24-52 weeks) of T1DM patients, insulin-SGLT2i co-treatment was associated with GI risk, and insulin-sotagliflozin co-treatment was associated with DKA and GI risk.

Abstract
BACKGROUND The novel sodium-glucose co-transporter 2 inhibitor (SGLT2i) potentially ameliorates heart failure and reduces cardiac arrhythmia. Cardiac fibrosis plays a pivotal role in the pathophysiology of HF and atrial myopathy, but the effect of SGLT2i on fibrogenesis remains to be elucidated. This study investigated whether SGLT2i directly modulates fibroblast activities and its underlying mechanisms. METHODS AND RESULTS Migration, proliferation analyses, intracellular pH assay, intracellular inositol triphosphate (IP3) assay, Ca2+ fluorescence imaging, and Western blotting were applied to human atrial fibroblasts. Empagliflozin (an SGLT2i, 1, or 5 μmol/L) reduced migration capability and collagen type I, and III production. Compared with control cells, empagliflozin (1 μmol/L)- treated atrial fibroblasts exhibited lower endoplasmic reticulum (ER) Ca2+ leakage, Ca2+ entry, inositol trisphosphate (IP3), lower expression of phosphorylated phospholipase C (PLC), and lower intracellular pH. In the presence of cariporide (an Na+-H+ exchanger (NHE) inhibitor, 10 μmol/L), control and empagliflozin (1 μmol/L)-treated atrial fibroblasts revealed similar intracellular pH, ER Ca2+ leakage, Ca2+ entry, phosphorylated PLC, pro-collagen type I, type III protein expression, and migration capability. Moreover, empagliflozin (10 mg/kg/day orally for 28 consecutive days) significantly increased left ventricle systolic function, ß-hydroxybutyrate and decreased atrial fibrosis, in isoproterenol (100 mg/kg, subcutaneous injection)-induced HF rats. CONCLUSIONS By inhibiting NHE, empagliflozin decreases the expression of phosphorylated PLC and IP3 production, thereby reducing ER Ca2+ release, extracellular Ca2+ entry and the profibrotic activities of atrial fibroblasts.

Glucose-Lowering Therapy beyond Insulin in Type 1 Diabetes: A Narrative Review on Existing Evidence from Randomized Controlled Trials and Clinical Perspective. Pharmaceutics 2022; 14:1180.

Abstract
Background: In Type 1 diabetes (T1D), according to the most recent guidelines, the everyday glucose-lowering treatment is still restricted to the use of subcutaneous insulin, while multiple therapeutic options exist for Type 2 diabetes (T2D). Methods: For this narrative review we unsystematically screened PubMed and Embase to identify clinical trials which investigated glucose-lowering agents as an adjunct to insulin treatment in people with T1D. Published studies up to March 2022 were included. We discuss the safety and efficacy in modifying cardiovascular risk factors for each drug, the current status of research, and provide a clinical perspective. Results: For several adjunct agents, in T1D, the scientific evidence demonstrates improvements in HbA1c, reductions in the risk of hypoglycemia, and achievements of lower insulin requirements, as well as positive effects on cardiovascular risk factors, such as blood lipids, blood pressure, and weight. As the prevalence of obesity, the major driver for double diabetes, is rising, weight and cardiovascular risk factor management is becoming increasingly important in people with T1D. Conclusions: Adjunct glucose-lowering agents, intended to be used in T2D, bear the potential to beneficially impact on cardiovascular risk factors when investigated in the T1D population and are suggested to be more extensively considered as potentially disease-modifying drugs in the future and should be investigated for hard cardiovascular endpoints.

Abstract
Background Adjunctive treatment with sodium-glucose co-transporters 2 inhibitors (SGLT2- I) has been successfully used in patients with type 1 diabetes mellitus (T1DM) in recent years to improve glycemic control and reduce body weight without increasing the risk of hypoglycemia; however, there is a scarcity of evidence for real-world experience in their use in T1DM Saudi patients. The purpose of this study was to evaluate the efficacy and safety of empagliflozin as off-label adjunctive therapy in Saudi patients with T1DM. Methods This study was a retrospective study for T1DM patients, who were prescribed empagliflozin as an adjunctive therapy. Baseline characteristics including age, changes in HbA1c, body weight, total daily insulin dose, lipid profile, and well as side effects such as urinary tract infections (UTIs) and diabetes ketoacidosis (DKA) were evaluated before and after initiation empagliflozin in 37 T1DM patients. Results The mean age was 25.8 ± 8.0 years, mean weight was 75.3 ± 14.8 kg, mean body mass index (BMI) was 28.1 ± 6.7 kg/m 2 , mean duration of diabetes was 10.1 ± 6.5 years, and mean HbA1c was 9.4 ± 1.4%. After a mean follow-up duration of 15.8 ± 6.0 months, the mean reduction in the HbA1c% from baseline was 0.82% ( p = 0.001) and mean weight reduction from baseline was 1.7 kg ( p = 0.097). The total daily insulin dose was decreased by 2.9 units. UTIs and DKA episodes were reported among 2.7% and 10.8% of the participants, respectively. Conclusion Empagliflozin in combination with insulin in overweight Saudi T1DM subjects resulted in a significant improvement in glycemic control, mild non-significant reduction in body weight, and a small but statistically significant reduction in the total daily insulin dose with a slight increase in the risk of DKA and UTIs. Further larger prospective studies are needed for better evaluation of the efficacy and safety of these agents in Saudi T1DM patients.

Abstract
Advances in insulin preparations and administration methods have produced a gradual improvement in glycemic control in patients with type 1 diabetes mellitus (DM). Nevertheless, glycated hemoglobin (HbA1c) levels in patients with type 1 DM are still poor compared to those in patients with type 2 DM. Here, we sought to assess the efficacy and safety of the sodium-glucose cotransporter 2 (SGLT2) inhibitor ipragliflozin (IPRA) in patients with type 1 DM. This study was retrospectively conducted with data from type 1 DM patients who had a history of IPRA therapy. The primary endpoint was HbA1c level at 24 weeks. The baseline characteristics of a total of 12 subjects were as follows: age, 50.1 ± 13.2 years; diabetes duration, 17.3 ± 10.5 years; body mass index (BMI), 22.9 ± 2.1 kg/m2; HbA1c, 8.8 ± 1.3%; and daily insulin dose, 0.60 ± 0.21 units/kg. IPRA decreased HbA1c levels to 8.2 ± 1.2% (p < 0.05) and reduced insulin dose to 0.52 ± 0.17 units/kg (p < 0.01) after 24 weeks. HbA1c value was particularly reduced in subjects with preserved C-peptide index. IPRA significantly reduced body weight by -1.4 ± 1.4 kg (p < 0.01) 16 weeks after starting treatment, with no further weight loss after 24 weeks. There were no instances of diabetic ketoacidosis or severe hypoglycemia. IPRA exerted beneficial effects on glycemic control without any severe adverse effects, and should be safe and effective when used in patients with type 1 DM with understanding of correspondence in sick day.

Effect of empagliflozin on ketone bodies in patients with stable chronic heart failure. Cardiovasc Diabetol 2021; 20:219. [PMID: 34753480 PMCID: PMC8579532 DOI: 10.1186/s12933-021-01410-7] [Citation(s) in RCA: 16] [Impact Index Per Article: 5.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/08/2021] [Accepted: 10/27/2021] [Indexed: 02/08/2023] Open
Abstract
BACKGROUND Recent studies indicated that sodium glucose cotransporter (SGLT)2 inhibition increases levels of ketone bodies in the blood in patients with type 1 and 2 diabetes. Other studies suggested that in patients with chronic heart failure (CHF), increased myocardial oxygen demand can be provided by ketone bodies as a fuel substrate. Experimental studies reported that ketone bodies, specifically beta-hydroxybutyrate (β-OHB) may increase blood pressure (BP) by impairing endothelium-dependant relaxation, thereby leading to increased vascular stiffness. In our study we assessed whether the SGLT 2 inhibition with empagliflozin increases ketone bodies in patients with stable CHF and whether such an increase impairs BP and vascular function. METHODS In a prospective, double blind, placebo controlled, parallel-group single centre study 75 patients with CHF (left ventricular ejection fraction 39.0 ± 8.2%) were randomised (2:1) to the SGLT-2 inhibitor empagliflozin 10 mg orally once daily or to placebo, 72 patients completed the study. After a run-in phase we evaluated at baseline BP by 24 h ambulatory blood pressure (ABP) monitoring, vascular stiffness parameters by the SphygmoCor system (AtCor Medical, Sydney, NSW, Australia) and fasting metabolic parameters, including β-OHB by an enzymatic assay (Beckman Coulter DxC 700 AU). The same measurements were repeated 12 weeks after treatment. In 19 of the 72 patients serum levels of β-OHB were beneath the lower border of our assay (< 0.05 mmol/l) therefore being excluded from the subsequent analysis. RESULTS In patients with stable CHF, treatment with empagliflozin (n = 36) was followed by an increase of β-OHB by 33.39% (p = 0.017), reduction in 24 h systolic (p = 0.038) and diastolic (p = 0.085) ABP, weight loss (p = 0.003) and decrease of central systolic BP (p = 0.008) and central pulse pressure (p = 0.008). The increase in β-OHB was related to an attenuated decrease of empagliflozin-induced 24 h systolic (r = 0.321, p = 0.069) and diastolic (r = 0.516, p = 0.002) ABP and less reduction of central systolic BP (r = 0.470, p = 0.009) and central pulse pressure (r = 0.391, p = 0.033). No significant changes were seen in any of these parameters after 12 weeks of treatment in the placebo group (n = 17). CONCLUSION In patients with stable CHF ketone bodies as assessed by β-OHB increased after treatment with empagliflozin. This increase led to an attenuation of the beneficial effects of empagliflozin on BP and vascular parameters. Trial registration The study was registered at http://www.clinicaltrials.gov (NCT03128528).

Abstract
Abstract
The objective of this meta-analysis study was to evaluate the comparative efficacy of empagliflozin (25 mg) with placebo in the treatment and management of type 1 diabetes mellitus. This study is a meta-analysis, so an ethical statement is not required. Different databases and individual journal websites like SCOPUS, Science direct, Cochrane review library etc. were used. The articles were evaluated based on the search and eligibility criteria. A total of five RCTs were incorporated in this meta-analysis. These studies contained a total of 1058 patients, including 526 patients with placebo (or control-treated patients), and 532 patients with empagliflozin (25 mg) treated combination. The mean follow-up time ranged from 7 days to 6 months. Overall, mean reduction in placebo was -0.50% and empa-treated was -0.85%, while the pooled WMD was 3.82 995% CI 1.20 – 5.88, p=0.0001). Regarding urinary glucose excretion, that the pooled WMD was 6.67 (95% CI 4.87-10.14, p=0.001) indicated a significant increase in empa-arm compared to placebo. No heterogeneity was found (I2 – 15.03%). This meta-analysis underlined the therapeutic benefit of empagliflozin as an adjunctive therapy for patients with type 1 diabetes.

Abstract
Despite the improvements in insulin therapy, many patients with type 1 diabetes mellitus (T1DM) do not achieve glycemic targets. Hypoglycemia and weight gain are important barriers in reaching these targets. Sodium/glucose cotransporter 2 (SGLT2) inhibitors lack these side effects and have an insulin-independent mechanism of action. Therefore, they might be useful in patients with T1DM. The authors discuss the safety and efficacy of SGLT2 inhibitors in T1DM. Several randomized controlled trials have evaluated dapagliflozin, sotagliflozin and empagliflozin in this population whereas fewer data are available for other members of this class. In these studies, SGLT2 inhibitors reduced HbA1c levels and body weight without a greater risk of hypoglycemia. However, a higher incidence of diabetic ketoacidosis (DKA) was observed in patients treated with these agents. SGLT2 inhibitors improve glycemic control in patients with T1DM but this effect is modest. Even though weight loss and the neutral effect on the incidence of hypoglycemia are advantages of these agents, the increased risk of DKA is a cause of concern. Overall, SGLT2 inhibitors should be used with caution and only in carefully selected patients with T1DM who are motivated, adherent to treatment, well-trained in recognizing DKA and are closely followed-up.

Abstract
AIM To examine the long-term efficacy and safety of dapagliflozin, a sodium-glucose co-transporter-2 (SGLT2) inhibitor used to treat type 1 diabetes, in the Japanese subpopulation of the DEPICT-2 study. MATERIALS AND METHODS Patients with type 1 diabetes were randomized to dapagliflozin 5 mg (n = 55), dapagliflozin 10 mg (n = 41) or placebo (n = 58) plus insulin for a 24-week, double-blind period followed by a 28-week, single-blind extension phase. RESULTS From baseline to 24 weeks, dapagliflozin reduced HbA1c compared with placebo (mean change of -0.58% and -0.80% for 5 and 10 mg, respectively), and an HbA1c reduction was observed up to 52 weeks. Compared with placebo, dapagliflozin 5 and 10 mg increased the proportion of patients achieving HbA1c reductions of 0.5% or more without severe hypoglycaemia events and reduced glycaemic variability assessed via continuous glucose monitoring. Both dapagliflozin doses decreased body weight and total daily insulin dose at 24 weeks compared with placebo; these reductions were maintained up to 52 weeks. Diabetic ketoacidosis occurred in both dapagliflozin groups (one and two cases, respectively) but not with placebo. CONCLUSIONS Efficacy and safety results from the Japanese subpopulation of the DEPICT-2 study were generally consistent with those from the overall population, indicating that long-term dapagliflozin adjunct to insulin therapy improves glycaemic control without an increased risk of hypoglycaemia but with a risk of diabetic ketoacidosis in Japanese patients with type 1 diabetes.

Abstract
AIMS The aim was to systematically review the efficacy and safety of sodium-glucose cotransporter inhibitor (SGLT2i) as an adjunct to insulin at different follow-up durations in randomized, double-blind clinical trials in patients with type 1 diabetes. METHODS We conducted a search on Medline, Embase, and the Cochrane Library for relevant studies published before May 2020. According to the duration of follow-up, the subgroup analysis included four periods: 1-4, 12-18, 24-26, and 52 weeks. In the five trials included both 24-26 and 52 weeks of follow-up, we compared the efficacy by the placebo-subtracted difference and changes in SGLT2i groups. RESULTS Fifteen trials including 7109 participants were analyzed. The combination of SGLT2i and insulin improved hemoglobin A1c (HbA1c), fasting plasma glucose (FPG), daily insulin dose, body weight, and blood pressure, which varied greatly by different follow-ups. Compared with %HbA1c at 24-26 weeks, placebo-subtracted differences and changes in the SGLT2i groups slightly increased. SGLT2i plus insulin treatment showed no difference in the occurrence of urinary tract infections (UTIs), hypoglycemia, or severe hypoglycemia but increased the risk of genital tract infections (GTIs) in a duration-dependent manner. SGLT2i treatment was associated with a significantly higher rate of ketone-related SAEs and diabetic ketoacidosis (DKA) at 52 weeks. CONCLUSION SGLT2i as an add-on therapy to insulin improved glycemic control and body weight and decreased the required dose of insulin without increasing the risk of hypoglycemia. However, after 6 months the benefits of SGLT2is on glycemic control may weaken and the risks of GTIs and DKA increased.

Abstract
The safety profiles of sodium-glucose co-transporter 2 (SGLT2) inhibitors may depend on races/ethnicities. We aimed to assess the safety profiles of SGLT2 inhibitors in Japanese patients with diabetes mellitus (DM). The electronic databases MEDLINE, CENTRAL, and Ichushi-web were searched for studies with no language restriction from their inception to August 2019. Trials were included in the analysis if they were randomized controlled trials (RCTs) comparing the effects of SGLT2 inhibitors with a placebo in Japanese patients with DM > 18 years and reporting HbA1c and at least 1 adverse event. We calculated risk ratios with 95% CIs and used a random-effects model. Of the 22 RCTs included in our review, only 1 included patients with type 1 DM. The durations of RCTs ranged between 4 and 24 weeks. In comparison with a placebo, SGLT2 inhibitors were associated with similar risks of hypoglycemia, urinary tract infection, genital infection, hypovolemia, and fracture. The outcomes of treatment with SGLT2 inhibitors among Japanese patients with DM suggest favorable safety profiles. However, further evidence from studies with a longer duration, involving more diverse populations, such as patients with different types of DM, or including individual SGLT2 inhibitors is needed to resolve the limitations of the present study.

Abstract
In clinical trials, sodium-glucose co-transporter (SGLT) inhibitor use as adjunct to insulin therapy in type 1 diabetes (T1D) provides glucometabolic benefits while diabetic ketoacidosis risk is increased. The SGLT2 inhibitor empagliflozin was evaluated in two phase III trials: EASE-2 and EASE-3. A low, 2.5-mg dose was included in EASE-3 only. As the efficacy of higher empagliflozin doses (i.e., 10 and 25 mg) in T1D has been established in EASE-2 and EASE-3, a modeling and simulation approach was used to generate additional supportive evidence on efficacy for the 2.5-mg dose. We present the methodology behind the development and validation of two modeling and simulation frameworks: M-EASE-1, a semi-mechanistic model integrating information on insulin, glucose, and glycated hemoglobin; and M-EASE-2, a descriptive model informed by prior information. Both models were developed independently of data from EASE-3. Simulations based on these models assessed efficacy in untested clinical trial scenarios. In this manner, the models provide supportive evidence for efficacy of low-dose empagliflozin 2.5 mg in patients with T1D, illustrating how pharmacometric analyses can support efficacy assessments in the context of limited data.

Abstract
AIMS/INTRODUCTION Sodium-glucose cotransporter 2 inhibitors (SGLT2i) are used worldwide because of their multiple benefits for patients with type 2 diabetes. The purpose of this study was to determine the efficacy and safety of SGLT2i in patients with type 1 diabetes. MATERIALS AND METHODS Patients with type 1 diabetes who had been treated with SGLT2i for >12 weeks were included in this retrospective observation study. We recorded the changes in body mass, insulin dose, blood and urine test data, and adverse events. The changes in day-to-day glucose variability, as the primary end-point, was evaluated using the interquartile range (P25/P75) of the ambulatory glucose data obtained using continuous glucose monitoring. RESULTS A total of 51 patients (37 women; mean age 52.7 years) were included. Glycated hemoglobin and body mass significantly decreased by 0.4% and 1.6 kg, respectively. The total required insulin dose decreased by 9.4% (42.7 ± 26.6-38.7 ± 24.3 units/day). Continuous glucose monitoring data were obtained from 30 patients. P25/P75 decreased by 17.6 ± 20.7% during SGLT2i treatment (P < 0.001). The percentage of time per day within the target glucose range of 70-180 mg/dL significantly increased (from 42.2 to 55.5%, P < 0.001), without an increase in the percentage of time spent in the hypoglycemic range (<70 mg/dL). Urinary ketone bodies were detected in four patients (7.8%), but none developed ketoacidosis. CONCLUSIONS SGLT2i improved day-to-day glucose variability and time in the target glucose range, without increasing frequency of hypoglycemia, in patients with type 1 diabetes, and reduced glycated hemoglobin, body mass and the required insulin dose.

Musso G, Sircana A, Saba F, Cassader M, Gambino R. Assessing the risk of ketoacidosis due to sodium-glucose cotransporter (SGLT)-2 inhibitors in patients with type 1 diabetes: A meta-analysis and meta-regression. PLoS Med 2020; 17:e1003461. [PMID: 33373368 PMCID: PMC7771708 DOI: 10.1371/journal.pmed.1003461] [Citation(s) in RCA: 30] [Impact Index Per Article: 7.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/14/2020] [Accepted: 11/23/2020] [Indexed: 12/15/2022] Open
Abstract
BACKGROUND Sodium-glucose cotransporter-2 (SGLT2) inhibitors (SGLT2i) showed benefits in type 1 diabetes mellitus (T1DM), but the risk of diabetic ketoacidosis (DKA) limits their use. Ability to predict DKA risk and therapeutic responses would enable appropriate patient selection for SGLT2i. We conducted a meta-analysis and meta-regression of randomized controlled trials (RCTs) evaluating SGLT2i in T1DM to assess moderators of the relative risk (RR) of DKA, of glycemic (HbA1c, fasting plasma glucose, continuous glucose monitoring parameters, insulin dose, and insulin sensitivity indices) and non-glycemic (body mass index (BMI), systolic BP, renal function, albuminuria, and diabetic eye disorders) efficacy, and of other safety outcomes (including hypoglycemia, infections, major adverse cardiovascular events, and death). METHODS AND FINDINGS We searched MEDLINE, Cochrane Library, EMBASE, ClinicalTrials.gov, Cochrane CENTRAL Register of Controlled Trials, and other electronic sources through August 30, 2020, for RCTs comparing SGLT2i with active comparators or placebo in adult patients with T1DM. Reviewers extracted data for relevant outcomes, performed random effects meta-analyses, subgroup analyses, and multivariable meta-regression. The strength of evidence was summarized with the GRADE approach. Among 9,914 records identified, 18 placebo-controlled RCTs (7,396 participants, 50% males, mean age 42 y (range 23 to 55 y), 5 different SGLT2i evaluated), were included. Main outcome measures were effect sizes and moderators of glycemic and non-glycemic efficacy and of safety outcomes. In a multivariable meta-regression model, baseline BMI (β = 0.439 [95% CI: 0.211, 0.666], p < 0.001) and estimated glucose disposal rate (eGDR) (β = -0.766 [-1.276, -0.256], p = 0.001) were associated with the RR of DKA (RR: 2.81; 95% CI:1.97, 4.01; p < 0.001, R2 = 61%). A model including also treatment-related parameters (insulin dose change-to-baseline insulin sensitivity ratio and volume depletion) explained 86% of variance across studies in the risk of DKA (R2 = 86%). The association of DKA with a BMI >27 kg/m2 and with an eGDR <8.3 mg/kg/min was confirmed also in subgroup analyses. Among efficacy outcomes, the novel findings were a reduction in albuminuria (WMD: -9.91, 95% CI: -16.26, -3.55 mg/g, p = 0.002), and in RR of diabetic eye disorders (RR: 0.27[0.11, 0.67], p = 0.005) associated with SGLT2i. A SGLT2i dose-response gradient was consistently observed for main efficacy outcomes, but not for adverse events (AEs). Overall, predictors of DKA and of other AEs differed substantially from those of glycemic and non-glycemic efficacy. A limitation of our analysis was the relatively short (≤52 weeks) duration of included RCTs. The potential relevance for clinical practice needs also to be confirmed by real-world prospective studies. CONCLUSIONS In T1DM, the risk of DKA and main therapeutic responses to SGLT2i are modified by baseline BMI and insulin resistance, by total insulin dose reduction-to-baseline insulin sensitivity ratio, and by volume depletion, which may enable the targeted use of these drugs in patients with the greatest benefit and the lowest risk of DKA.

Abstract
BACKGROUND The placebo response in patients with diabetes mellitus is very common. A systematic evaluation needs to be updated with the current evidence about the placebo response in diabetes mellitus and the associated factors in clinical trials of anti-diabetic medicine. METHODS Literature research was conducted in Medline, Embase, the Cochrane Central Register of Controlled Trials, and ClinicalTrials.gov for studies published between the date of inception and June 2019. Randomized placebo-controlled trials conducted in type 1and type 2 diabetes mellitus (T1DM/T2DM) were included. Random-effects model and meta-regression analysis were accordingly used. This meta-analysis was registered in PROSPERO as CRD42014009373. RESULTS Significantly weight elevation (effect size (ES) = 0.33 kg, 95% CI, 0.03 to 0.61 kg) was observed in patients with placebo treatments in T1DM subgroup while significantly HbA1c reduction (ES = - 0.12%, 95% CI, - 0.16 to - 0.07%) and weight reduction (ES = - 0.40 kg, 95% CI, - 0.50 to - 0.29 kg) were observed in patients with placebo treatments in T2DM subgroup. Greater HbA1c reduction was observed in patients with injectable placebo treatments (ES = - 0.22%, 95% CI, - 0.32 to - 0.11%) versus oral types (ES = - 0.09%, 95% CI, - 0.14 to - 0.04%) in T2DM (P = 0.03). Older age (β = - 0.01, 95% CI, - 0.02 to - 0.01, P < 0.01) and longer diabetes duration (β = - 0.02, 95% CI, - 0.03 to - 0.21 × 10-2, P = 0.03) was significantly associated with more HbA1c reduction by placebo in T1DM. However, younger age (β = 0.02, 95% CI, 0.01 to 0.03, P = 0.01), lower male percentage (β = 0.01, 95% CI, 0.22 × 10-2, 0.01, P < 0.01), higher baseline BMI (β = - 0.02, 95% CI, - 0.04 to - 0.26 × 10-2, P = 0.02), and higher baseline HbA1c (β = - 0.09, 95% CI, - 0.16 to - 0.01, P = 0.02) were significantly associated with more HbA1c reduction by placebo in T2DM. Shorter diabetes duration (β = 0.06, 95% CI, 0.06 to 0.10, P < 0.01) was significantly associated with more weight reduction by placebo in T2DM. However, the associations between baseline BMI, baseline HbA1c, and placebo response were insignificant after the adjusted analyses. CONCLUSION The placebo response in diabetes mellitus was systematically outlined. Age, sex, disease severity (indirectly reflected by baseline BMI and baseline HbA1c), and disease duration were associated with placebo response in diabetes mellitus. The association between baseline BMI, baseline HbA1c, and placebo response may be the result of regression to the mean.

Abstract
AIM To conduct an overall safety assessment of sodium-glucose co-transporter-2 (SGLT-2) inhibitors used for the treatment of patients with type 1 diabetes (T1D), including ketoacidosis, genital infection, volume depletion, liver and kidney injury events, cardiovascular events, diarrhea and severe hypoglycaemia. MATERIALS AND METHODS We searched three databases (Pubmed, Embase and the Cochrane Library) for randomized controlled trials that treated T1D by using SGLT-2 inhibitors from 2000 to 5 March 2020. RESULTS Of the 1653 articles identified that fit our search criteria, 22 studies included qualitative-based results, eight of which were randomized clinical trials that included quantitative-based results. Compared with the control group, the SGLT-2 inhibitors treatment group was found to have had an increased incidence of ketoacidosis (P < .00001, OR 4.34, 95% CI [2.37, 7.96], I2 = 18%), events leading to discontinuation (P < .0001, OR 1.76, 95% CI [1.34, 2.31], I2 = 0%), genital infection (P < .00001, OR 3.64, 95% CI [2.82, 4.70], I2 = 0%), volume depletion (P = .006, OR 2.10, 95% CI [1.23, 3.59], I2 = 4%) and diarrhoea (P = .008, OR 1.64, 95% CI [1.14, 2.36], I2 = 0%). However, according to subgroup analysis, the risk of diarrhoea was dose-related. The incidence of urinary tract infection, cardiovascular events, renal events, liver injury and fracture was not significantly different for the treatment group compared with the control group. CONCLUSIONS Despite showing some promise as a treatment approach, the application of SGLT-2 inhibitors for patients with T1D should be considered with caution.

Clin Ther 2020; 42:1787-1798.e3. [PMID: 32839028 DOI: 10.1016/j.clinthera.2020.07.009] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/24/2020] [Revised: 07/07/2020] [Accepted: 07/08/2020] [Indexed: 11/29/2022]
Abstract
PURPOSE To characterize the pharmacokinetic and pharmacodynamic (PK/PD) relationship of ipragliflozin in Japanese patients with type 1 diabetes mellitus (T1DM) and type 2 diabetes mellitus (T2DM) and to determine the appropriate dose regimen for a Phase III study of ipragliflozin in Japanese patients with T1DM. METHODS The PK (AUC24h of plasma ipragliflozin) and PD (renal glucose clearance) properties in patients with T1DM and T2DM were assessed in 2 independent clinical pharmacologic studies of ipragliflozin. The same maximum efficacy (Emax) model described the PK/PD relationship in patients with T1DM and T2DM. Changes in fasting plasma glucose (FPG) in T1DM patients were simulated by applying a previously established FPG model for ipragliflozin in patients with T2DM. FINDINGS Data from 42 patients with T1DM and 28 patients with T2DM were used. Comparable AUC24h of plasma ipragliflozin and similar dose dependency were observed on day 14 between patients with T1DM and those with T2DM. Decreases in renal glucose clearance were comparable regardless of the ipragliflozin dose in both groups of patients. The estimated mean Emax and AUC24h producing 50% of Emax (EX50) were 45.1 mL/min (95% CI, 37.0-53.2 mL/min) and 2160 ng·h/mL (95% CI, 929-3390 ng·h/mL), respectively, in all patients with T1DM and T2DM. Observed FPG in patients with T1DM was reproduced well by the simulation from the previously established FPG model. IMPLICATIONS The PK/PD properties for ipragliflozin were comparable between patients with T1DM and T2DM, suggesting no substantial difference in PK/PD relationships in both patient populations. The dose regimen used for patients with T2DM was also recommended for a Phase III study in Japanese patients with T1DM. ClinicalTrials.gov identifiers: NCT01023945 and NCT02529449.

Abstract
Aims: We evaluated the real-life efficacy and safety of empagliflozin in combination with optimized insulin therapy in patients with type 1 diabetes (T1D). Methods: This was a prospective study, including 27 patients with T1D treated with insulin therapy to whom empagliflozin was added according to an off-label protocol approved for use in clinical practice. The primary end point was the change in HbA1c 52 weeks after the addition of empagliflozin to insulin therapy. Blood pressure (BP), weight, and safety were also assessed. Results: At week 52, the addition of empagliflozin significantly reduced HbA1c from 8.0% ± 0.7% to 7.2% ± 0.8% (P < 0.001). The mean percentage of time in range for capillary glucose monitoring increased from 50% to 62% (P = 0.008) in parallel to a -0.08 IU/(kg·day) reduction in insulin requirements (P = 0.031). There was also a reduction in the body weight (-8 kg) and in systolic BP from 134 to 127 mmHg (P < 0.001). The most commonly reported adverse events were genitourinary infections (10 episodes in 52 weeks of follow-up). One patient developed an episode of mild diabetic ketoacidosis that motivated empagliflozin withdrawal. No severe hypoglycemic events were registered. Conclusions: Our results suggested that the use of empagliflozin following a strict off-label protocol may represent an effective and safe option in real life among patients with T1D, improving metabolic control, and ameliorating some cardiovascular risk factors.

Abstract
OBJECTIVES While empagliflozin (25 mg) is used to treat type-2 diabetes mellitus patients with optimum renal functioning, its efficacy and safety in type-1 diabetes mellitus (T1DM) is not yet established. Therefore, this study aimed to compare insulin-treated T1DM patients' (with adequate renal functioning) glycemic and blood pressure control between the 25 mg empagliflozin recipients and placebo recipients. METHODS Parallel-arm randomized controlled trials comparing the effect of daily administered 25 mg empagliflozin tablets in adjunct to insulin treatment with placebo and insulin treatment in T1DM patients with an estimated glomerular filtration rate of 45 mL/min/1.73 m2 or more were eligible for inclusion. Trials were searched in PubMed, EMBASE, SCOPUS, and CENTRAL with no restriction on date and language. Risk of bias of trials was assessed and mean and standard deviation of glycated hemoglobin (HbA1c, in %), systolic blood pressure (mmHg), and diastolic blood pressure (mmHg) at the end of the trial period were collected, and random-effects meta-analysis was done to estimate the weighted mean difference (WMD). The meta-analysis was done in Stata statistical software. This study was conducted in June 2019. RESULTS Three relatively small-sized trials published between 2015 and 2018 were eligible for review and analyses. The trials suffered from unclear risk of performance and detection bias. The HbA1c reduction favored the intervention group (WMD = -0.478, 95% confidence intervals = -0.766--0.189, P = 0.001; I2 = 0%). The WMD of blood pressure (systolic and diastolic) did not vary between the treatment groups. CONCLUSION Evidence (of moderate quality) suggests that daily administration of empagliflozin 25 mg tablets in adjunct to insulin in T1DM patients with optimum kidney functioning is useful to achieve glycemic control compared to placebo and insulin therapy. However, the effect on blood pressure remained indistinguishable between the compared interventions.

Abstract
BACKGROUND The safety and efficacy of sodium glucose co-transporter 2 (SGLT2) inhibitors in a dose-dependent manner for type 1 diabetes mellitus (T1DM) are unclear. METHODS Randomized clinical trials (RCT) were searched from PubMed, EMBASE, the Cochrane Library, Web of Science and ClinicalTrials until August 2018. RESULTS Thirteen RCT with 5397 participants were included. SGLT2 inhibitors were proved to be effective in glycemic control and weight loss in T1DM. In the subgroups of different doses, SGLT2 inhibitors exhibited reductions in glycated haemoglobin, bodyweight, fasting plasma glucose, mean daily glucose, basal insulin dose, bolus insulin dose, estimated glomerular filtration rate and systolic blood pressure, and elevations in the mean amplitude of glucose excursions, and percentage of time in target glucose range in a dose-dependent manner. Reductions in total insulin dose and urinary glucose excretion were dose-independent. SGLT2 inhibitors did not induce hypoglycemia, severe hypoglycemia, cardiovascular events, bone fracture and all-cause mortality, but increased the risk of adverse events (AE), adverse events related to the drug treatment, infections, diabetic ketoacidosis (DKA) and renal disease correlated with dosage. CONCLUSIONS SGLT2 inhibitors in high and moderate doses can achieve a better outcome on efficacy, but may induce a higher risk of adverse events, especially DKA.

Abstract
Objective: To review phase 3 trials of sodium-glucose cotransporter (SGLT) inhibitors in type 1 diabetes mellitus (T1DM) patients. Data Sources: A literature search of Ovid MEDLINE databases (1946 through May 17, 2019) limited to English-language human clinical trials was conducted using the following terms: sodium-glucose transporter 2 inhibitors, canagliflozin, dapagliflozin, empagliflozin, sotagliflozin, ertugliflozin, ipragliflozin, or remogliflozin combined with type 1 diabetes mellitus. Results were verified via Google Scholar and clinicaltrials.gov. Study Selection and Data Extraction: Articles were included if they were phase 3 trials in adults with T1DM. Data Synthesis: Phase 3 trials are available for dapagliflozin, empagliflozin, and sotagliflozin. All 3 drugs demonstrated statistically significant reductions in hemoglobin A1C, weight, and total daily insulin dose without an increased risk of hypoglycemia in up to 52 weeks of therapy. The incidence of diabetic ketoacidosis (DKA) was higher in patients on a SGLT inhibitor at all doses, with the exception of empagliflozin 2.5 mg (0.8% vs 1.2% with placebo). Relevance to Patient Care and Clinical Practice: SGLT inhibitors are potential adjuncts to insulin in T1DM patients, providing clinically meaningful benefits. Regulatory bodies have either approved or are reviewing these agents for use in T1DM. Clinicians should be familiar with the DKA risk associated with SGLT inhibitors and utilize DKA risk-mitigation strategies. Empagliflozin 2.5 mg warrants additional investigation given its efficacy without an increased incidence of DKA. Conclusions: Phase 3 trial data of SGLT inhibitors provide evidence for sustained efficacy in T1DM patients. Appropriate patient selection for therapy and routine monitoring are essential to minimize associated risks.

Abstract
Sodium-glucose cotransporter 2 (SGLT2) inhibitors are drugs for diabetes and might prevent heart failure. In this study, we investigated the effects of tofogliflozin, an SGLT2 inhibitor, on cardiac hypertrophy and metabolism in hypertensive rats fed a high-fat diet. Dahl salt-sensitive (DS) rats, hypertensive model rats, and Dahl salt-resistant (DR) rats, non-hypertensive model rats, were fed a high-salt and high-fat diet containing tofogliflozin (0.005%) for 9 weeks to examine the effects of this drug on cardiac hypertrophy and metabolism. Tofogliflozin tended to suppress a rise of the systolic blood pressure, relative to the control, throughout the treatment period in both DR and DS rats, and significantly suppress a rise of the systolic blood pressure, relative to the control, at the 9th week in DS rats. Tofogliflozin reduced cardiac hypertrophy (heart weight/body weight) not only in DS rats but also in DR rats. Histological analysis showed that tofogliflozin significantly decreased cardiomyocyte hypertrophy and perivascular fibrosis in both DS and DR rats. Tofogliflozin significantly decreased the expression levels of genes related to cardiac hypertrophy (encoding for natriuretic peptides A and B and interleukin-6), and to cardiac fibrosis (encoding for transforming growth factor-β1 and collagen type IV), in DS rats. Recent studies have shown that hypertrophied and failing hearts shift to oxidizing ketone bodies as a significant fuel source. We also performed metabolome analysis for ventricular myocardial tissue. Tofogliflozin reduced 3-hydroxybutyrate, a ketone body, and significantly decreased the expression levels of β-hydroxybutyrate dehydrogenase 1 and 3-oxoacid CoA-transferase, which are related to ketone oxidization. In conclusion, tofogliflozin ameliorated cardiac hypertrophy and fibrosis along with reduction of ketone usage in myocardial tissue.

Abstract
Use of sodium glucose cotransporter (SGLT) inhibitors are a well-established therapeutic option in type 2 diabetes (T2D) with a variety of proven therapeutic benefits. They have become a pillar of current treatment guidelines. In type 1 diabetes (T1D), initial exploratory studies have shown benefits in glycemic control, weight control, and cardiovascular risk parameters, leading to trials aiming for regulatory submission with several agents. Results from four 1-year trials, which included a total of 3052 patients, are now available, demonstrating promising findings that target the unmet needs of patients with T1D with a novel insulin-independent adjunct therapy. However, these positive effects must be balanced against the risks associated with this class of drugs. Specifically, current T1D studies have shown an increased risk of diabetic ketoacidosis (DKA), which, in some cases, presented with only slightly elevated glucose levels. While this complication may be clinically manageable once detected, the metabolic shift towards ketogenesis associated with this class of agents mandates appropriate patient selection. Currently, there are no validated tools for DKA risk assessment. Although the experience gained in studies and off-label use provides some indication for appropriate patient selection, this would have to be evaluated closely in the event that these drugs would receive regulatory approval. Risk mitigation includes training in ketone measurement (preferably as blood β-hydroxybutyrate testing), teaching the concept of euglycemic DKA, and providing a clear treatment algorithm to avoid progression of ketosis to full-blown DKA. Because similar unmet needs also exist in pediatric population studies, risk mitigation in youth should be initiated as well to allow an evidence-based, risk-benefit assessment in this vulnerable population.

Abstract
Diabetes mellitus prevalence is increasing worldwide leading to increased morbidity and mortality through diabetes related microvascular and macrovascular disease. The treatment of hypertension has been shown to be a major therapeutic intervention for the prevention of cardiovascular events and other diabetes related complications in diabetes. Sodium-glucose co-transporter inhibitors (SGLT2i) are newly introduced anti-diabetes drugs that lower blood glucose by the inhibition of glucose reuptake and the induction of glycosuria. However, there is increasing evidence showing their cardiovascular benefit beyond the improvement of glycemic control. Here we review the latest findings on the effect of SGLT2i on blood pressure in diabetes.

Abstract
<b><i>Background:</i></b> This study aims to contrast the side effects of treatment with sodium-glucose cotransporter-2 inhibitors (SGLT2i) and placebo in insulin-treated adult type 1 diabetes mellitus (T1DM) patients. <b><i>Methods:</i></b> Double-blinded randomized controlled trials that compare the above outcome were searched in electronic databases. Next, the risk of bias in eligible studies was assessed, and comparable outcomes were compared by a random-effects meta-analysis. <b><i>Results:</i></b> Seven eligible papers comprising about 3,900 participants were studied. All trials suffered from an unclear risk of detection bias and performance bias. In comparison with the placebo group, the risk of genital infection (RR = 3.22, <i>p</i> < 0.001, 95% CI 2.31–4.49, <i>I</i><sup>2</sup> = 0%) and diabetic ketoacidosis (RR = 2.66, <i>p</i> = 0.002, 95% CI 1.45–4.89, <i>I</i><sup>2</sup> = 0%) was higher in the SGLT2i-treated group. <b><i>Conclusion:</i></b> SGLT2i treatment increased the risk of genital infection and diabetic ketoacidosis in adult insulin-treated T1DM patients.

Empagliflozin as Adjunctive to Insulin Therapy in Type 1 Diabetes: The EASE Trials. Diabetes Care 2018; 41:2560-2569. [PMID: 30287422 DOI: 10.2337/dc18-1749] [Citation(s) in RCA: 210] [Impact Index Per Article: 35.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/16/2018] [Accepted: 09/20/2018] [Indexed: 02/07/2023]
Abstract
OBJECTIVE To evaluate the safety and efficacy of empagliflozin 10- and 25-mg doses plus a unique lower dose (2.5 mg) as adjunct to intensified insulin in patients with type 1 diabetes (T1D). RESEARCH DESIGN AND METHODS The EASE (Empagliflozin as Adjunctive to inSulin thErapy) program (N = 1,707) included two double-blind, placebo-controlled phase 3 trials: EASE-2 with empagliflozin 10 mg (n = 243), 25 mg (n = 244), and placebo (n = 243), 52-week treatment; and EASE-3 with empagliflozin 2.5 mg (n = 241), 10 mg (n = 248), 25 mg (n = 245), and placebo (n = 241), 26-week treatment. Together they evaluated empagliflozin 10 mg and 25 mg, doses currently approved in treatment of type 2 diabetes, and additionally 2.5 mg on 26-week change in glycated hemoglobin (primary end point) and weight, glucose time-in-range (>70 to ≤180 mg/dL), insulin dose, blood pressure, and hypoglycemia. RESULTS The observed largest mean placebo-subtracted glycated hemoglobin reductions were -0.28% (95% CI -0.42, -0.15) for 2.5 mg, -0.54% (-0.65, -0.42) for 10 mg, and -0.53% (-0.65, -0.42) for 25 mg (all P < 0.0001). Empagliflozin 2.5/10/25 mg doses, respectively, reduced mean weight by -1.8/-3.0/-3.4 kg (all P < 0.0001); increased glucose time-in-range by +1.0/+2.9/+3.1 h/day (P < 0.0001 for 10 and 25 mg); lowered total daily insulin dose by -6.4/-13.3/-12.7% (all P < 0.0001); and decreased systolic blood pressure by -2.1/-3.9/-3.7 mmHg (all P < 0.05). Genital infections occurred more frequently on empagliflozin. Adjudicated diabetic ketoacidosis occurred more with empagliflozin 10 mg (4.3%) and 25 mg (3.3%) but was comparable between empagliflozin 2.5 mg (0.8%) and placebo (1.2%). Severe hypoglycemia was rare and frequency was similar between empagliflozin and placebo. CONCLUSIONS Empagliflozin improved glycemic control and weight in T1D without increasing hypoglycemia. Ketoacidosis rate was comparable between empagliflozin 2.5 mg and placebo but increased with 10 mg and 25 mg. Ketone monitoring for early ketoacidosis detection and intervention and lower empagliflozin doses may help to reduce this risk.

Empagliflozin as adjunct to insulin in Japanese participants with type 1 diabetes: Results of a 4-week, double-blind, randomized, placebo-controlled phase 2 trial. Diabetes Obes Metab 2018; 20:2190-2199. [PMID: 29766633 PMCID: PMC6099358 DOI: 10.1111/dom.13351] [Citation(s) in RCA: 34] [Impact Index Per Article: 5.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/27/2018] [Revised: 04/27/2018] [Accepted: 05/05/2018] [Indexed: 12/12/2022]
Abstract
AIMS This phase 2, double-blind, randomized, placebo-controlled trial (ClinicalTrials.gov NCT02702011) with 4 sites in Japan investigated the pharmacodynamics (PD), pharmacokinetics (PK) and safety profile of empagliflozin in Japanese participants with type 1 diabetes mellitus (T1DM) as adjunctive therapy to insulin. MATERIALS AND METHODS Participants using multiple daily injections of insulin for ≥12 months, with HbA1c of 7.5%-10.0%, entered a 2-week, open-label, placebo run-in period, followed by a 4-week, double-blind period during which participants were randomized 1:1:1:1 to receive empagliflozin 2.5 mg (n = 13), empagliflozin 10 mg (n = 12), empagliflozin 25 mg (n = 12) or placebo (n = 11). The primary objective was to assess the effect of empagliflozin vs placebo on urinary glucose excretion (UGE) after 7 days of treatment. RESULTS PD: Empagliflozin resulted in a dose-dependent significant increase in 24-hour UGE compared with placebo (UGE placebo-corrected mean [95% confidence interval] change from baseline: 2.5 mg, 65.10 [43.29, 86.90] g/24 h; 10 mg, 81.19 [58.80, 103.58] g/24 h; 25 mg, 98.11 [75.91, 120.31] g/24 h). After 4 weeks of treatment, UGE increase was associated with improved glycaemic control, reduced body weight and decreased insulin needs. Empagliflozin treatment also resulted in dose-dependent increases in serum ketone bodies and free fatty acids. PK: Plasma empagliflozin levels increased in a dose-dependent manner and peaked at 1.5 hours. In this short study, empagliflozin was well tolerated, with no increase in rate of hypoglycaemia and no diabetic ketoacidosis events reported. CONCLUSIONS Based on this short-duration phase 2 study, the PK/PD profile of empagliflozin in Japanese participants with T1DM is comparable to that of non-Japanese participants.
