Abstract
Introduction: Sodium glucose cotransporter inhibitors may increase beta-hydroxybutyrate (BHB) in insulin-requiring patients. We determined factors associated with BHB changes from baseline (ΔBHB) and diabetic ketoacidosis (DKA) in patients with type 1 diabetes (T1D) receiving sotagliflozin as an insulin adjunct. Research Design and Methods: This post hoc analysis compared ΔBHB levels in adults with T1D receiving sotagliflozin 400 mg or placebo for 6 months. We evaluated clinical and metabolic factors associated with ΔBHB and used logistic regression models to determine predictors associated with BHB values >0.6 and >1.5 mmol/L (inTandem3 population; N = 1402) or with DKA events in a pooled analysis (inTandem1-3; N = 2453). Results: From baseline (median, 0.13 mmol/L), median fasting BHB increased by 0.04 mmol/L (95% confidence interval, 0.03-0.05; P < 0.001) at 24 weeks with sotagliflozin versus placebo; 67% of patients had no or minimal changes in BHB over time. Factors associated with on-treatment BHB >0.6 or >1.5 mmol/L included baseline BHB and sotagliflozin use. Age, insulin pump use, sotagliflozin use, baseline BHB, and ΔBHB were significantly associated with DKA episodes. Independent of treatment, DKA risk increased by 18% with each 0.1-mmol/L increase in baseline BHB and by 8% with each 0.1-mmol/L increase from baseline. Conclusion: Incremental increases in baseline BHB and ΔBHB were associated with a higher DKA risk independent of treatment. Adding sotagliflozin to insulin increased median BHB over 24 weeks in patients with T1D and was associated with increased DKA events. These results highlight the importance of BHB testing and monitoring and individualizing patient education on DKA risk, mitigation, identification, and treatment.

Abstract
To clarify the frequency of hypoglycemia in patients with type 1 diabetes mellitus receiving dapagliflozin combination therapy to reduce their basal insulin dose. Sixty subjects were assigned to two groups according to their basal insulin-to-total daily dose (TDD) ratio: group A (basal insulin/TDD <40%) and group B (≥40%). Reduction of the basal insulin dose was instituted in group B, but not in group A. The number of hypoglycemic events per day and ketosis frequency were the primary and secondary endpoints, respectively. The hypoglycemia frequency before and after the intervention was 0.23 and 0.26 times/day in group A and 0.19 and 0.23 times/day in group B, respectively, with no significant difference between the groups. The total insulin dose reduction was approximately 10% in both groups. Ketosis frequency increased significantly after the intervention (from 0.013 to 0.086 times/day in group A and 0.013 to 0.059 times/day in group B). Time-in-range, mean amplitude of glycemic excursion, and glycated hemoglobin A1c improved in both groups. No significant difference in hypoglycemia frequency was observed between patients with and without reduction of the basal insulin dose. The combination therapy improved glycemic control and patient satisfaction regarding hyperglycemia. Nevertheless, adequate attention to ketosis is crucial.

Diabetes Obes Metab 2021; 23:1496-1504.

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
OBJECTIVES Dapagliflozin (Dapa) could potentially be used to treat type 1 diabetes mellitus. We tested the hypothesis that it would influence blood lipid levels and visceral fat accumulation in a rodent diabetic model. METHODS We used three groups of male Wistar rats: Controls, streptozotocin (STZ)-treated rats and STZ-treated orally with Dapa (STZ+Dapa), 10 mg/kg/day for six weeks. Blood glucose and serum lipids levels were determined. Plasma levels of lipases (hormone-sensitive lipase, HSL and lipoprotein lipase, LPL), adipokines (leptin and adiponectin) and proinflammatory cytokines [tumour necrosis factor-alpha (TNFα) and interleukin-6 (IL-6)] were determined by ELISA assays. mRNA levels in the perirenal fat were determined by real-time PCR. KEY FINDINGS Dapa suppressed STZ-related hyperglycemia by 20% (P < 0.05) and increased serum HDL when compared to the controls and the STZ-only treated rats (both P < 0.05). STZ treatment caused elevations of other serum lipids that were resistant to Dapa treatment. Dapa treatment also increased both plasma and visceral fat mRNA levels of leptin, LPL and IL-6, while decreasing plasma and fat expressions of HSL and TNFα compared to the STZ-only treated rats (all P < 0.05). CONCLUSIONS Our results suggest that Dapa, in addition to its antidiabetic effect, also influences the function of adipose tissue which could be beneficial in the treatment of diabetes.

Abstract
Sodium glucose cotransporter-2 (SGLT2) is a sodium-dependent glucose transporter responsible for renal absorption of glucose. Dapagliflozin is an SGLT2 inhibitor used in patients with type 1 diabetes to promote urinary glucose excretion, but to date, randomized controlled trials (RCTs) to evaluate the effect of this drug in this disease have not been systematically evaluated. Therefore, the aim of the present study was to evaluate the efficacy and safety of dapagliflozin, as an adjuvant therapy to insulin, in the treatment of type 1 diabetes mellitus through a systematic review and meta-analysis. The Cochrane Library Database, Medline and Embase databases were used to search articles published between January 1st 2004 and February 5th 2020 with no language restrictions relating to RCTs. After extracting the data, the quality of the RCTs was evaluated and the data were statistically analyzed. A total of 4 RCTs with 1,691 participants were included. Dapagliflozin resulted in decreased glycosylated hemoglobin A1c (0.40-0.45%), body weight (2.52-3.85 kg), mean daily glucose (0.76-0.99 mmol/l) and mean amplitude of glucose excursion (0.54-1.07 mmol/l; all with P<0.00001) compared to placebo. Subgroup analysis by dose indicated no significant difference in all efficacy outcome indicators between dapagliflozin at 5 and at 10 mg (P>0.1). Compared with placebo, the use of dapagliflozin in patients with type 1 diabetes increased the risk of adverse events and serious adverse events (P<0.05), but did not increase the risks of infection, diabetic ketoacidosis (DKA) and discontinuation due to adverse events. Analysis by dose group suggested that no significant difference in all safety outcome indicators between dapagliflozin at 5 and at 10 mg (P>0.1). In conclusion, dapagliflozin had a significant effect on type 1 diabetes. However, the use of dapagliflozin significantly increased the incidence of adverse events and serious adverse events compared with placebo. Dapagliflozin-assisted short-term (24 weeks) insulin therapy for type 1 diabetes did not increase the risk of DKA but additional high-quality studies are required to determine its long-term efficacy and safety.

Abstract
Dapagliflozin (SGLT-2 inhibitor) and sotagliflozin (SGLT1/2 inhibitor) are two of the drugs of SGLT inhibitor class which have been recommended by the National Institute for Health and Care Excellence (NICE) in people with type 1 diabetes with BMI ≥27 kg/m2 . Dapagliflozin is licensed in the UK for use in the NHS while sotagliflozin may be available in future. These and possibly other SGLT inhibitors may be increasingly used in people with type 1 diabetes as new licences are obtained. These drugs have the potential to improve glycaemic control in people with type 1 diabetes with the added benefit of weight loss, better control of blood pressure and more time in optimal glucose range. However, SGLT inhibitors are associated with a higher incidence of diabetic ketoacidosis without significant hyperglycaemia. The present ABCD/Diabetes UK joint updated position statement is to guide people with type 1 diabetes and clinicians using these drugs help mitigate this risk and other potential complications. Particularly, caution needs to be exercised in people who are at risk of diabetic ketoacidosis due to low calorie diets, illnesses, injuries, starvation, excessive exercise, excessive alcohol consumption and reduced insulin administration among other precipitating factors for diabetic ketoacidosis.

Abstract
Formulation of insulin analogs and its delivery are developed in over recent years but glycemic control in most patients with type-1 diabetes mellitus (DM) is not adequate yet. The aim of this meta-analysis is to evaluate the efficacy of dapagliflozin in patients with type-1 DM. The MEDLINE/PubMed, Scopus, Embase, Cochrane Central Register of Controlled Trials (CENTRAL), and Web of Science databases were searched up to Aug 2020 to identify the potential literature. Random-effects model (DerSimonian and Laird method) was used to estimate the pooled effect size as weighted mean difference (WMD) with 95 % confidence interval (CI). Five randomized placebo-controlled trials with 11 arms were included in the quantitative analysis. The pooled results suggested a significant reduction in glycated hemoglobin A1C (HbA1C; WMD: -0.36 %, 95 % CI: -0.55, -0.18), body weight (WMD: -4.02 kg, 95 % CI: -4.78, -3.25), and total daily insulin dose (TDID; WMD: -10.36 %, 95 % CI: -13.42, -7.29), as well as an increase in 24-h urinary glucose excretion (24-h UGE; WMD: 90.02 g/24-h, 95 % CI: 72.96, 107.09) in dapagliflozin group compared to control group. Dose of dapagliflozin had a significant effect on body weight reduction (Coef = -3.7, p = 0.01) and 24-h UGE (coef = 0.85, p = 0.005). Pooled results of this meta-analysis identified a significant reduction in HbA1c levels, body weight, and TDID, and a substantial increase in 24-h UGE in patients who received dapagliflozin versus placebo.

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: 27] [Impact Index Per Article: 6.8] [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
OBJECTIVE To evaluate the incidence and risk factors for diabetic ketoacidosis (DKA) and related adverse events (AEs) in adults with type 1 diabetes treated with sotagliflozin adjunctive to insulin. RESEARCH DESIGN AND METHODS Data from two identically designed, 52-week, randomized studies were pooled and analyzed for DKA, changes in β-hydroxybutyrate (BHB), and percentage of patients with BHB >0.6 and >1.5 mmol/L. The patients were administered placebo, sotagliflozin 200 mg, or sotagliflozin 400 mg once daily. RESULTS A total of 191 ketosis-related AEs were reported, and 98 underwent adjudication. Of these, 37 events (36 patients) were adjudicated as DKA, with an exposure-adjusted incidence rate of 0.2, 3.1, and 4.2 events per 100 patient-years for placebo, sotagliflozin 200 mg, and sotagliflozin 400 mg, respectively. No patient died of a DKA event. From a baseline BHB of ∼0.13 mmol/L, sotagliflozin treatment led to a small median increase over 52 weeks (≤0.05 mmol/L at all time points). Of sotagliflozin-treated patients, approximately 47% and 7% had ≥1 BHB measurement >0.6 mmol/L and >1.5 mmol/L, respectively (vs. 20% and 2%, respectively, of placebo-treated patients). Subsequent to the implementation of a risk mitigation plan, annualized DKA incidence was lower versus preimplementation in both the sotagliflozin 200 and 400 mg groups. CONCLUSIONS In patients with type 1 diabetes, confirmed DKA incidence increased when sotagliflozin was added to insulin compared with insulin alone. A lower incidence of DKA was observed following the implementation of an enhanced risk mitigation plan, suggesting that this risk can be managed with patient education.

[PMID: 32436630 DOI: 10.1111/dom.14092] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/03/2020] [Revised: 05/12/2020] [Accepted: 05/16/2020] [Indexed: 12/14/2022]
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.

Abstract
AIMS To investigate the safety and tolerability of 5 and 10 mg dapagliflozin added to insulin therapy over 52 weeks in Japanese patients with inadequately controlled type 1 diabetes mellitus (T1DM). MATERIALS AND METHODS This randomized, open-label, parallel-group, multicentre phase III clinical trial was conducted from October 26, 2015 to June 15, 2017. The primary endpoint was the occurrence of adverse events such as hypoglycaemia and diabetic ketoacidosis. Secondary endpoints included changes in glycaemic parameters, total daily insulin dosage and body weight over time. The efficacy of dapagliflozin in patients stratified by body mass index (BMI) <25.0 and ≥25.0 kg/m2 was evaluated in a subgroup analysis. RESULTS In total, 151 patients received 5 mg (n = 76) or 10 mg (n = 75) dapagliflozin once daily for 52 weeks. Adverse events were observed in 88.2% and 73.3% of patients in the 5 and 10 mg dapagliflozin groups, respectively. Severe hypoglycaemia was reported in 2.6% (n = 2) and 6.7% (n = 5) of patients, and diabetic ketoacidosis in 2.6% (n = 2) and 1.3% (n = 1) of patients in the 5 and 10 mg dapagliflozin groups, respectively. The adjusted mean (95% confidence interval) changes in glycated haemoglobin at week 52 were -0.33% (-0.50, -0.15) and -0.36% (-0.53, -0.18) in the 5 and 10 mg dapagliflozin groups, respectively. There were no differences in efficacy parameters when stratified by BMI. CONCLUSIONS This study demonstrated the long-term safety and tolerability of dapagliflozin added to insulin therapy in Japanese patients with inadequately controlled T1DM.

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
AIMS To assess the dose-related effects of sotagliflozin, a novel dual inhibitor of sodium-glucose co-transporters-1 and -2, in type 1 diabetes (T1D). MATERIALS AND METHODS In this 12-week, multicentre, randomized, double-blind, placebo-controlled dose-ranging trial, adults with T1D were randomized to once-daily placebo (n = 36) or sotagliflozin 75 mg (n = 35), 200 mg (n = 35) or 400 mg (n = 35). Insulin was maintained at baseline doses. The primary endpoint was least squares mean (LSM) change in glycated haemoglobin (HbA1c) from baseline. Other endpoints included proportion of participants with ≥0.5% HbA1c reduction and assessments of 2-hour postprandial glucose (PPG), weight, and urinary glucose excretion (UGE). RESULTS From a mean baseline of 8.0% ± 0.8% (full study population), placebo-adjusted LSM HbA1c decreased by 0.3% (P = .07), 0.5% (P < .001) and 0.4% (P = .006) with sotagliflozin 75 mg, 200 mg and 400 mg, respectively, at week 12. In the placebo and sotagliflozin 75 mg, 200 mg and 400 mg groups, 33.3%, 37.1%, 80.0% and 65.7% of participants achieved an HbA1c reduction ≥0.5%. Placebo-adjusted PPG decreased by 22.2 mg/dL (P = .28), 28.7 mg/dL (P = .16) and 50.2 mg/dL (P = .013), UGE increased by 41.8 g/d (P = .006), 57.7 g/d (P < .001) and 70.5 g/d (P < .001), and weight decreased by 1.3 kg (P = .038), 2.4 kg (P < .001) and 2.6 kg (P < .001) with sotagliflozin 75 mg, 200 mg and 400 mg, respectively. One case of severe hypoglycaemia occurred in each sotagliflozin group and one case of diabetic ketoacidosis (DKA) occurred with sotagliflozin 400 mg. CONCLUSIONS Combined with stable insulin doses, sotagliflozin 200 mg and 400 mg improved glycaemic control and weight in adults with T1D. Sotagliflozin 400 mg reduced PPG levels. UGE increased with all sotagliflozin doses. Rates of severe hypoglycaemia and DKA were low (NCT02459899).

Abstract
Sodium-glucose cotransporter (SGLT) inhibitors added to insulin therapy have been proposed as treatment strategy for type 1 diabetes (T1D). We thus conducted a meta-analysis of randomized controlled trials (RCTs) to assess the efficacy and adverse effects of this combination in T1D. We searched the PubMed, EMBASE, and Cochrane Library databases and ClinicalTrials.gov for RCTs. Statistical analyses were performed using STATA 15. Ten eligible placebo-controlled trials involving 5961 patients were included. Compared with placebo, SGLT inhibitors were associated with a reduction in HbA1c of -0.39% (95% CI, -0.43 to -0.36), an improved mean amplitude of glucose excursion (MAGE) of -14.81 mg/dL (95% CI, -19.08 to -10.54), and a reduction in body weight of -3.47% (95% CI, -3.78 to -3.16), as well as no increased relative risk of hypoglycaemia (1.01; 95% CI, 0.99-1.02) or severe hypoglycaemia (0.91; 95% CI, 0.77-1.07). SGLT inhibitors decreased fasting plasma glucose and insulin requirement but increased the risk of genital infection (3.57; 95% CI, 2.97-4.29) and diabetic ketoacidosis (3.11; 95% CI, 2.11-4.58). However, the very low dose empagliflozin (2.5 mg) did not increase the risk of diabetic ketoacidosis (risk ratio [RR] 0.67; 95% CI, 0.11-3.95). SGLT inhibitors had no effect on overall adverse events, urinary tract infection, or bone fracture but slightly increased the risk of serious adverse events (1.35; 95% CI, 1.16-1.58), severe adverse events (1.84; 95% CI, 1.20-2.84), adverse events leading to discontinuation (1.50; 95% CI, 1.22-1.84), drug-related adverse events (1.78; 95% CI, 1.44-2.19), and diarrhoea (1.54; 95% CI, 1.15-2.05). Although adverse events exist, the available data provide evidence that the combination of SGLT inhibitors with basal insulin treatment is beneficial in patients with T1D.

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
AIMS To quantitatively describe the relationship between dapagliflozin systemic exposure and HbA1c response among patients with type 1 diabetes mellitus (T1DM) and assess the potential impact of covariate effects. MATERIALS AND METHODS Individual longitudinal HbA1c data from two phase 3 studies in patients with T1DM (24-week treatment with once-daily dapagliflozin 5 or 10 mg or placebo, with adjustable insulin) were analyzed using a non-linear mixed effect modeling approach. Area under the concentration curve was used to measure dapagliflozin systemic exposure. Baseline HbA1c, estimated glomerular filtration rate, reduction in total insulin dose, baseline glucose concentrations, age, sex, race (Asian vs. non-Asian), and insulin administration method (multiple daily injections vs. insulin pump) were assessed as covariates. RESULTS A maximum effect (Emax ) model identified a positive exposure-response relationship. Model-predicted placebo-corrected HbA1c reductions after 24 weeks for dapagliflozin 5- and 10-mg doses were - 0.42% [95% confidence interval (CI) -0.47 to -0.36) and - 0.45% (95% CI -0.50 to -0.40), respectively; baseline HbA1c was ~8.4%. This was in good agreement with actual observations from both studies. Baseline HbA1c was a significant covariate: patients with higher baseline HbA1c were predicted to have greater HbA1c reductions. CONCLUSIONS The relationship between dapagliflozin systemic exposure and HbA1c response was successfully described in patients with T1DM. None of the tested covariates affected the efficacy of dapagliflozin to a clinically relevant extent. Therefore, no dose adjustment of dapagliflozin is required in patients with T1DM based on the tested covariates. ClinicalTrials.gov, NCT02268214; NCT02460978.

Abstract
OBJECTIVE This pooled analysis assessed continuous glucose monitoring (CGM) in patients with inadequately controlled type 1 diabetes (HbA1c ≥7.7 to ≤11.0% [≥61 to ≤97 mmol/mol]) who received dapagliflozin as an adjunct to adjustable insulin. RESEARCH DESIGN AND METHODS CGM data were pooled from two 24-week, double-blind, randomized, phase 3 studies: Dapagliflozin Evaluation in Patients with Inadequately Controlled Type 1 Diabetes (DEPICT-1 and DEPICT-2). These studies comprised 1,591 patients receiving dapagliflozin 5 mg (n = 530), dapagliflozin 10 mg (n = 529), or placebo (n = 532). RESULTS Baseline characteristics were balanced between treatment groups. Patients receiving dapagliflozin 5 mg or 10 mg both spent more time with blood glucose in the range >3.9 to ≤10.0 mmol/L (>70 to ≤180 mg/dL) over 24 h than those receiving the placebo. The adjusted mean (SE) change from baseline at week 24 was 6.48% (0.60) with dapagliflozin 5 mg, 8.08% (0.60) with dapagliflozin 10 mg, and -2.59% (0.61) with placebo. At week 24, the mean amplitude of glucose excursion over 24 h, mean 24-h glucose values, and postprandial glucose values were also improved in patients receiving dapagliflozin over those receiving placebo. No marked differences were found at week 24 between dapagliflozin 5 or 10 mg and placebo in the percentage of glucose values ≤3.9 mmol/L (≤70 mg/dL) or ≤3.0 mmol/L (≤54 mg/dL) over 24 h, or in nocturnal (0000-0559 h) glucose values ≤3.9 mmol/L (≤70 mg/dL). CONCLUSIONS In patients with type 1 diabetes, treatment with dapagliflozin over 24 weeks improved time in range, mean glucose, and glycemic variability without increasing the time spent in the range indicating hypoglycemia.

Abstract
OBJECTIVE To assess the efficacy and safety of dual sodium glucose cotransporter (SGLT) 1/2 inhibitor sotagliflozin in type 1 diabetes mellitus. DESIGN Meta-analysis of randomised controlled trials. DATA SOURCES Medline; Cochrane Library; Embase; international meeting abstracts; international and national clinical trial registries; and websites of US, European, and Japanese regulatory authorities, up to 10 January 2019. ELIGIBILITY CRITERIA FOR SELECTING STUDIES Randomised controlled trials evaluating the effect of sotagliflozin versus active comparators or placebo on glycaemic and non-glycaemic outcomes and on adverse events in type 1 diabetes in participants older than 18. Three reviewers extracted data for study characteristics, outcomes of interest, and risk of bias and summarised strength of evidence using the grading of recommendations assessment, development, and evaluation approach. Main outcomes were pooled using random effects models. RESULTS Of 739 records identified, six randomised placebo controlled trials (n=3238, duration 4-52 weeks) were included. Sotagliflozin reduced levels of glycated haemoglobin (HbA1c; weighted mean difference -0.34% (95% confidence interval -0.41% to -0.27%), P<0.001); fasting plasma glucose (-16.98 mg/dL, -22.1 to -11.9; 1 mg/dL=0.0555 mmol/L) and two hour-postprandial plasma glucose (-39.2 mg/dL, -50.4 to -28.1); and daily total, basal, and bolus insulin dose (-8.99%, -10.93% to -7.05%; -8.03%, -10.14% to -5.93%; -9.14%, -12.17% to -6.12%; respectively). Sotagliflozin improved time in range (weighted mean difference 9.73%, 6.66% to 12.81%) and other continuous glucose monitoring parameters, and reduced body weight (-3.54%, -3.98% to -3.09%), systolic blood pressure (-3.85 mm Hg, -4.76 to -2.93), and albuminuria (albumin:creatinine ratio -14.57 mg/g, -26.87 to -2.28). Sotagliflozin reduced hypoglycaemia (weighted mean difference -9.09 events per patient year, -13.82 to -4.36) and severe hypoglycaemia (relative risk 0.69, 0.49 to 0.98). However, the drug increased the risk of ketoacidosis (relative risk 3.93, 1.94 to 7.96), genital tract infections (3.12, 2.14 to 4.54), diarrhoea (1.50, 1.08 to 2.10), and volume depletion events (2.19, 1.10 to 4.36). Initial HbA1c and basal insulin dose adjustment were associated with the risk of diabetic ketoacidosis. A sotagliflozin dose of 400 mg/day was associated with a greater improvement in most glycaemic and non-glycaemic outcomes than the 200 mg/day dose, without increasing the risk of adverse events. The quality of evidence was high to moderate for most outcomes, but low for major adverse cardiovascular events and all cause death. The relatively short duration of trials prevented assessment of long term outcomes. CONCLUSIONS In type 1 diabetes, sotagliflozin improves glycaemic and non-glycaemic outcomes and reduces hypoglycaemia rate and severe hypoglycaemia. The risk of diabetic ketoacidosis could be minimised by appropriate patient selection and down-titration of the basal insulin dose.

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
AIMS To assess the dapagliflozin exposure-response relationship in Japanese and non-Japanese patients with type 1 diabetes mellitus (T1DM) and investigate if a dose adjustment is required in Japanese patients. MATERIALS AND METHODS Data from two clinical studies were used to develop a non-linear mixed effects model describing the relationship between dapagliflozin exposure (area under the concentration curve) and response (24-hour urinary glucose excretion [UGE]) in Japanese and non-Japanese patients with T1DM. The effects of patient-level characteristics (covariates; identified using a stepwise procedure) on response was also assessed. Simulations were performed using median-normalized covariate values. RESULTS Data from 84 patients were included. Average self-monitored blood glucose (SMBG) at day 7, change from baseline in total insulin dose at day 7, and baseline estimated glomerular filtration rate (eGFR) all had a significant effect on 24-hours UGE, with SMBG being the most influential. Dapagliflozin systemic exposure for matching doses and baseline eGFR was similar between Japanese and non-Japanese patients; however, higher SMBG and a greater reduction in total insulin dose was observed in the Japanese population. When the significant covariates were included, the model fit the data well for both populations, and accurately predicted exposure-response in the Japanese and non-Japanese populations, in agreement with the observed data. CONCLUSIONS There was no difference in dapagliflozin exposure-response in Japanese and non-Japanese patients with T1DM once differences in renal function, glycaemic control and insulin dose reductions between studies were considered. Therefore, no dose adjustment is recommended in Japanese patients with T1DM.

Abstract
Many patients with type 1 diabetes (T1D) struggle to achieve glycaemic control and experience significant fluctuations in glucose concentrations, despite insulin treatment. Sodium-glucose co-transporter (SGLT)-2 inhibitors and dual SGLT-1/2 inhibitors increase glucose elimination via the kidneys and reduce hyperglycaemia via insulin-independent mechanisms. This review examines available efficacy and safety data for these agents under investigation as adjunctive therapy for T1D. Across randomized trials of up to 52 weeks, SGLT-2 inhibitors or SGLT-1/2 inhibitors as an adjunct to insulin demonstrated significant reductions in glycated haemoglobin, glucose exposure, and measures of glycaemic variability, as well as increased time in the target glycaemic range, compared with placebo. Non-glycaemic benefits included reductions in body weight and insulin doses, as well as improvements in some cardiovascular risk factors and treatment satisfaction. SGLT-2 inhibitors and SGLT-1/2 inhibitors were associated with similar rates of hypoglycaemia but a higher incidence of genitourinary infections, compared with placebo. Diabetic ketoacidosis occurred more often with SGLT-2 inhibitors and SGLT-1/2 inhibitors vs placebo, although the incidence was generally low. Risk mitigation strategies in light of clinical trial data are also discussed. Positive data from randomized controlled trials of the SGLT-2 inhibitor dapagliflozin have led to the approval of dapagliflozin as an adjunct to insulin in adults with T1D having body mass index ≥27 kg/m2 in whom insulin does not provide adequate glycaemic control in Europe and to approval as an adjunct to insulin for adults with T1D in Japan.

Abstract
For type 1 diabetes patients with inadequate glycemic control, one treatment option is to increase the insulin dose (scenario 1), which should not give rise to a “metabolic imbalance.” A second option is additional treatment with a sodium–glucose cotransporter 2 inhibitor, which might lead to a “metabolic imbalance” (scenario 2). A reduction in insulin dose in addition to administration of a sodium–glucose cotransporter 2 inhibitor might further increase the “metabolic imbalance” (scenario 3).![]()

Abstract
OBJECTIVE This 24-week, double-blinded, phase 3 clinical trial (DEPICT-2; ClinicalTrials.gov, NCT02460978) evaluated efficacy and safety of dapagliflozin as adjunct therapy to adjustable insulin in patients with inadequately controlled type 1 diabetes (HbA1c 7.5-10.5%). RESEARCH DESIGN AND METHODS Patients were randomized 1:1:1 to dapagliflozin 5 mg (n = 271), dapagliflozin 10 mg (n = 270), or placebo (n = 272) plus insulin. Insulin dose was adjusted by investigators according to self-monitored glucose readings, local guidance, and individual circumstances. RESULTS Baseline characteristics were balanced between treatment groups. At week 24, dapagliflozin significantly decreased HbA1c (primary outcome; difference vs. placebo: dapagliflozin 5 mg -0.37% [95% CI -0.49, -0.26], dapagliflozin 10 mg -0.42% [-0.53, -0.30]), total daily insulin dose (-10.78% [-13.73, -7.72] and -11.08% [-14.04, -8.02], respectively), and body weight (-3.21% [-3.96, -2.45] and -3.74% [-4.49, -2.99], respectively) (P < 0.0001 for all). Mean interstitial glucose, amplitude of glucose excursion, and percent of readings within target glycemic range (>70 to ≤180 mg/dL) versus placebo were significantly improved. More patients receiving dapagliflozin achieved a reduction in HbA1c ≥0.5% without severe hypoglycemia compared with placebo. Adverse events were reported for 72.7%, 67.0%, and 63.2% of patients receiving dapagliflozin 5 mg, dapagliflozin 10 mg, and placebo, respectively. Hypoglycemia, including severe hypoglycemia, was balanced between groups. There were more adjudicated definite diabetic ketoacidosis (DKA) events with dapagliflozin: 2.6%, 2.2%, and 0% for dapagliflozin 5 mg, dapagliflozin 10 mg, and placebo, respectively. CONCLUSIONS Dapagliflozin as adjunct therapy to adjustable insulin in patients with type 1 diabetes was well tolerated and improved glycemic control with no increase in hypoglycemia versus placebo but with more DKA events.

Abstract
PURPOSE OF REVIEW To identify and evaluate the recent trials of sodium-glucose cotransporter 1 and 2 (SGLT1 and SGLT2, respectively) inhibitor use in patients with type 1 diabetes (T1D). SGLT-2 inhibitors have been approved by the Food and Drug Administration (FDA) and are effectively used in the treatment of type 2 diabetes (T2D). However, many studies (phase I-III) have validated their effects beyond improving glycemic control and have shown potential adjunctive use in adult patients with T1D treated with insulin therapy alone. RECENT FINDINGS A review of the literature showed that there is a potential adjunctive role for the SGLT inhibitors with insulin in T1D for improving glycemic control. The inTandem3 (A phase III study to evaluate the safety of sotagliflozin in patients with type 1 diabetes who have inadequate glycemic control with insulin therapy alone) and the DEPICT-1 (Dapagliflozin evaluation in patients with inadequately controlled type 1 diabetes) trials demonstrated significant benefits in adult patients with T1D. The SGLT inhibitors may become the first oral medication to be approved for adjunctive use in T1D. SUMMARY The risk of diabetic ketoacidosis still remains a concern, but considering additional benefits beyond glucose control, with proper counseling and education, these medications may allow a larger number of patients to achieve target glucose control without weight gain or increased risk of hypoglycemia.

Abstract
New treatments for type 1 diabetes are an unmet need. We investigated the efficacy and safety of adding sodium-glucose co-transporter-2 (SGLT2) inhibitors to insulin for type 1 diabetes by conducting a meta-analysis of prospective randomized, placebo-controlled trials. A search of electronic databases up to October 2017 identified 1361 studies, of which 14 were investigated (N = 4591). Meta-analysis showed that SGLT2 inhibitor therapy significantly reduced glycated haemoglobin (HbA1c) concentration by 0.4% (95% confidence interval [CI] 0.35, 0.46; P < .001, I2 = 0%), fasting plasma glucose by 1.14 mmol/L (95% CI 0.8,1.47), body weight by 2.68 kg (95% CI 2.0, 3.36), and systolic blood pressure by 3.37 mmHg (95% CI 1.46, 5.28). In addition, bolus insulin decreased by 3.6 units/day (95% CI 2.0, 5.3), and basal insulin decreased by 4.2 units/day (95% CI 2.2, 6.3). Continuous glucose monitoring showed a decrease in glucose excursions compared with placebo, with reduced variation of mean blood glucose, glucose standard deviation, and mean amplitude of glucose excursion. There was no significant increase in the rate of hypoglycaemia or severe hypoglycaemia; however, SGLT2 inhibitor therapy increased diabetic ketoacidosis (odds ratio [OR] 3.38) and genital tract infection (OR 3.44). Add-on SGLT2 inhibitor therapy might be advantageous for type 1 diabetes, but its use should be considered carefully.

Abstract
INTRODUCTION There is a clear unmet clinical need in people with Type 1 diabetes (T1DM) considering present day insulin therapy. New insulin analogues and novel technologies allowing more tailored insulin administration have improved the quality of life of people with T1DM, but issues like hypoglycemia, weight gain and variability in glucose profiles remain problematic. Areas covered: In this review, the clinical efficacy, safety and tolerability of dapagliflozin, a sodium-glucose cotransporter type 2 inhibitor, in type 1 diabetes (T1DM) is described based on a review of phase 2 and 3 studies to date. Expert opinion: Dapagliflozin has shown promising results as an adjunct therapy in T1DM, resulting in better glucose control, weight loss and lower blood pressure. No increase in hypoglycemia risk, in particular severe hypoglycemia, was observed, but, in comparison with reports in Type 2 diabetes (T2DM), genital infections were more prevalent. Dapagliflozin use was accompanied with decreases in insulin doses, but, to date, only a low risk of diabetic ketoacidosis (DKA) was reported. However, caution is needed when interpreting this data, arising from well controlled clinical trials, with intensive education programs around ketone measurements and DKA prevention. Further studies will need to establish how high the DKA risk is and how to mitigate this in a real-world setting.

Abstract
BACKGROUND Dapagliflozin is a sodium-glucose cotransporter-2 inhibitor approved for the treatment of type 2 diabetes. We aimed to assess the efficacy and safety of dapagliflozin as an add-on to adjustable insulin in patients with inadequately controlled type 1 diabetes. METHODS DEPICT-1 was a double-blind, randomised, parallel-controlled, three-arm, phase 3, multicentre study done at 143 sites in 17 countries. Eligible patients were aged 18-75 years and had inadequately controlled type 1 diabetes (HbA1c between ≥7·7% and ≤11·0% [≥61·0 mmol/mol and ≤97·0 mmol/mol]) and had been prescribed insulin for at least 12 months before enrolment. After an 8 week lead-in period to optimise diabetes management, patients were randomly assigned (1:1:1) using an interactive voice response system to dapagliflozin 5 mg or 10 mg once daily, given orally, or matched placebo. Randomisation was stratified by current use of continuous glucose monitoring, method of insulin administration, and baseline HbA1c. The primary efficacy outcome was the change from baseline in HbA1c after 24 weeks of treatment in the full analysis set, which consisted of all randomly assigned patients who received at least one dose of study drug. An additional 55 patients who were incorrectly and non-randomly allocated to only dapagliflozin treatment groups were included in the safety analysis set. This study was registered with ClinicalTrials.gov, number NCT02268214; data collection for the present analysis was completed on Jan 4, 2017, and a 28 week extension phase is ongoing. FINDINGS Between Nov 11, 2014, and April 16, 2016, 833 patients were assigned to treatment groups and included in safety analyses (dapagliflozin 5 mg [n=277] vs dapagliflozin 10 mg [n=296] vs placebo [n=260]; 778 of these patients were randomly assigned and included in the full analysis set for efficacy analyses (259 vs 259 vs 260; difference due to randomisation error affecting 55 patients). Mean baseline HbA1c was 8·53% (70 mmol/mol; SD 0·67% [7·3 mmol/mol]). At week 24, both doses of dapagliflozin significantly reduced HbA1c compared with placebo (mean difference from baseline to week 24 for dapagliflozin 5 mg vs placebo was -0·42% [95% CI -0·56 to -0·28; p<0·0001] and for dapagliflozin 10 mg vs placebo was -0·45% [-0·58 to -0·31; p<0·0001]). Among patients in the dapagliflozin 5 mg (n=277), dapagliflozin 10 mg (n=296), and placebo (n=260) groups, the most common adverse events were nasopharyngitis (38 [14%] vs 36 [12%] vs 39 [15%]), urinary tract infection (19 [7%] vs 11 [4%] vs 13 [5%]), upper respiratory tract infection (15 [5%] vs 15 [5%] vs 11 [4%]), and headache (12 [4%] vs 17 [6%] vs 11 [4%]). Hypoglycaemia occurred in 220 (79%), 235 (79%), and 207 (80%) patients in the dapagliflozin 5 mg, dapagliflozin 10 mg, and placebo groups, respectively; severe hypoglycaemia occurred in 21 (8%), 19 (6%), and 19 (7%) patients, respectively. Adjudicated definite diabetic ketoacidosis occurred in four (1%) patients in the dapagliflozin 5 mg group, five (2%) in the dapagliflozin 10 mg group, and three (1%) in the placebo group. INTERPRETATION Our results suggest that dapagliflozin is a promising adjunct treatment to insulin to improve glycaemic control in patients with inadequately controlled type 1 diabetes.

Abstract
Youth with type 1 diabetes (T1D) infrequently achieve HbA1c targets. Therefore, this placebo-controlled, randomized, crossover study was set up to assess the safety, effect and pharmacokinetics of a single dose of 10 mg dapagliflozin (DAPA) as add-on to insulin in relationship to HbA1c in youth. A total of 33 youths (14 males, median age 16 years, diabetes duration 8 years) were included and stratified into 3 baseline HbA1c categories (<7.5%, 7.5%-9.0% or >9.0; n = 11 each). During the study period of 24 hours, intravenous insulin administration and glucose-infusion kept blood glucose levels at 160 to 220 mg/dL. DAPA reduced mean insulin dose by 13.6% ( P < .0001 by ANOVA) and increased urinary glucose excretion by 610% (143.4 vs 22.4 g/24 h; P < .0001), both irrespective of baseline HbA1c. Six independent episodes in 6 patients with plasma ß-hydroxybutyrate levels between ≥0.6 and <1.0 mmol/L were observed after liquid meal challenges, 5 episodes in the DAPA group and 1 in the placebo group. This study provides a proof-of-concept, irrespective of preexisting HbA1c levels, for adjunct SGLT2-inhibitor therapy in the paediatric age group by lowering insulin dose and increasing glucose excretion.
