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?ConclusionsCombined 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).

Project description:OBJECTIVE:To evaluate effects of the dual sodium-glucose cotransporter (SGLT) 1 and SGLT2 inhibitor sotagliflozin in combination with insulin on glucose time in range (TIR) and glucose excursions, postprandial glucose (PPG), and other glycemic metrics in adults with type 1 diabetes using masked continuous glucose monitoring (CGM). RESEARCH DESIGN AND METHODS:Data sets from the inTandem1 (clinical trial reg. no. NCT02384941) and inTandem2 (clinical trial reg. no. NCT02421510) double-blind randomized trials evaluating sotagliflozin versus placebo in adults with type 1 diabetes treated with optimized insulin were pooled for analyses of masked CGM data from a subset of participants in each trial. The pooled cohort included patients randomized to receive placebo (n = 93), sotagliflozin 200 mg (n = 89), or sotagliflozin 400 mg (n = 96). The primary outcome was change from baseline to week 24 in glucose TIR (3.9-10.0 mmol/L [70-180 mg/dL]). Secondary end points included time below and above the target range and 2-h PPG level assessed after a standardized mixed meal. RESULTS:Mean percentage of glucose TIR/percentage time spent at <3.9 mmol/L (<70 mg/dL) during week 24 was 51.6%/5.9%, 57.8%/5.5%, and 64.2%/5.5% with placebo, sotagliflozin 200 mg, and sotagliflozin 400 mg, respectively, which corresponded to a placebo-adjusted change from a baseline of +5.4%/-0.3% (P = 0.026; +1.3/-0.1 h/day) for sotagliflozin 200 mg and +11.7%/-0.1% (P < 0.001; +2.8/-0.02 h/day) for sotagliflozin 400 mg. Placebo-adjusted PPG reductions were 1.9 ± 0.7 mmol/L (35 ± 13 mg/dL; P = 0.004) and 2.8 ± 0.7 mmol/L (50 ± 13 mg/dL; P < 0.001) with sotagliflozin 200 and 400 mg, respectively. CONCLUSIONS:Combined with optimized insulin in type 1 diabetes, sotagliflozin significantly increased glucose TIR without increasing time spent at <3.9 mmol/L and reduced PPG, thereby improving glycemic control.

Project description:OBJECTIVE:Evaluate the efficacy and safety of the dual sodium-glucose cotransporter 1 (SGLT1) and SGLT2 inhibitor sotagliflozin in combination with optimized insulin in type 1 diabetes (T1D). RESEARCH DESIGN AND METHODS:The inTandem1 trial, a double-blind, 52-week phase 3 trial, randomized North American adults with T1D to placebo (n = 268), sotagliflozin 200 mg (n = 263), or sotagliflozin 400 mg (n = 262) after 6 weeks of insulin optimization. The primary end point was HbA1c change from baseline at 24 weeks. HbA1c, weight, and safety were also assessed through 52 weeks. RESULTS:From a mean baseline of 7.57%, placebo-adjusted HbA1c reductions were 0.36% and 0.41% with sotagliflozin 200 and 400 mg, respectively, at 24 weeks and 0.25% and 0.31% at 52 weeks (all P < 0.001). Among patients with a baseline HbA1c ?7.0%, an HbA1c <7% was achieved by 15.7%, 27.2%, and 40.3% of patients receiving placebo, sotagliflozin 200 mg, and sotagliflozin 400 mg, respectively (P ? 0.003 vs. placebo) at 24 weeks. At 52 weeks, mean treatment differences between sotagliflozin 400 mg and placebo were -1.08 mmol/L for fasting plasma glucose, -4.32 kg for weight, and -15.63% for bolus insulin dose and -11.87% for basal insulin dose (all P < 0.001). Diabetes Treatment Satisfaction Questionnaire scores increased significantly by 2.5 points with sotagliflozin versus placebo (P < 0.001) at 24 weeks. Genital mycotic infections and diarrhea occurred more frequently with sotagliflozin. Adjudicated diabetic ketoacidosis (DKA) occurred in 9 (3.4%) and 11 (4.2%) patients receiving sotagliflozin 200 and 400 mg, respectively, and in 1 (0.4%) receiving placebo. Severe hypoglycemia occurred in 17 (6.5%) patients from each sotagliflozin group and 26 (9.7%) patients receiving placebo. CONCLUSIONS:In a 1-year T1D study, sotagliflozin combined with optimized insulin therapy was associated with sustained HbA1c reduction, weight loss, lower insulin dose, fewer episodes of severe hypoglycemia, improved patient-reported outcomes, and more DKA relative to placebo (ClinicalTrials.gov, NCT02384941).

Project description:Background: Hypoglycemia rates usually increase when insulin treatment is intensified to improve glycemic control. We evaluated (post hoc) hypoglycemic rates in adult patients with type 1 diabetes (T1D) on sotagliflozin (a dual sodium-glucose cotransporter [SGLT] 1 and 2 inhibitor) in two phase 3, 52-week clinical trials (inTandem 1 and 2; NCT02384941 and NCT02421510). Materials and Methods: We analyzed rates of documented hypoglycemia (level 1, blood glucose ?54 to <70?mg/dL) and clinically important hypoglycemia (level 2, glucose <54?mg/dL) in a patient-level pooled analysis (n?=?1362) using a negative binomial model adjusted for hemoglobin A1c (HbA1c) at 52 weeks in patients receiving placebo, sotagliflozin 200?mg, and sotagliflozin 400?mg. Results: Rates of level 1 hypoglycemia events per patient-year were 58.25 (95% confidence interval: 50.26-67.50) with placebo, 44.86 (38.83-51.82; P?=?0.0138 vs. placebo) with sotagliflozin 200?mg, and 45.68 (39.52-52.81; P?=?0.0220) with sotagliflozin 400?mg. Sotagliflozin was also associated with lower rates of level 2 hypoglycemia: 15.95 (14.37-17.70), 11.51 (10.39-12.76; P?<?0.0001), and 11.13 (10.03-12.35; P?<?0.0001) for placebo and sotagliflozin 200 and 400?mg, respectively. The difference in rates of hypoglycemia with sotagliflozin versus placebo became more pronounced as HbA1c decreased. Conclusions: At week 52, level 1 and 2 hypoglycemia events were 22% to 30% less frequent with sotagliflozin added to optimized insulin therapy versus placebo in adults with T1D at any HbA1c level, with greater differences at lower HbA1c values. These findings support the use of sotagliflozin as an insulin adjunct in T1D.

Project description:<h4>Objective</h4>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.<h4>Research design and methods</h4>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.<h4>Results</h4>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.<h4>Conclusions</h4>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.

Project description:<b><i>Background:</i></b> Young adults with type 1 diabetes (T1D) tend to have higher A1C than older adults and are at increased risk for diabetic ketoacidosis (DKA). Oral adjuncts to insulin have not been previously studied in this population. <b><i>Methods:</i></b> In this phase 2, multicenter, randomized, double-blind, placebo-controlled, parallel-group study, adults aged 18-30 years with T1D and A1C ≥9.0% were randomly assigned to placebo (<i>n</i> = 42) or sotagliflozin 400 mg (<i>n</i> = 43), in addition to insulin for 12 weeks. Insulin doses were adjusted to meet glucose targets (preprandial 80-130 mg/dL, postprandial <180 mg/dL). The primary endpoint was change from baseline in A1C at week 12. <b><i>Results:</i></b> From a baseline of 9.8%, mean A1C decreased by 1.0% with placebo and 1.3% with sotagliflozin (-0.4% [95% confidence interval (CI): -0.8 to 0.1]; <i>P</i> = 0.10 vs. placebo). In the prespecified A1C ≤10.0% subgroup, the treatment difference was -0.8% (-1.3 to -0.2; <i>P</i> = 0.006), favoring sotagliflozin. Overall, relative to placebo, postprandial glucose (PPG) decreased by 56.6 mg/dL (-89.7 to -23.6; <i>P</i> < 0.001) and weight decreased by 2.37 kg (-3.5 to -1.2; <i>P</i> < 0.001). More patients achieved an A1C <7.0% with sotagliflozin (16.3%) than placebo (2.4%; <i>P</i> = 0.026). Rates of documented hypoglycemia and severe hypoglycemia were similar between groups. One DKA event occurred with placebo, and none occurred with sotagliflozin. <b><i>Conclusions:</i></b> In young adults with T1D and suboptimal glycemic control, sotagliflozin plus insulin for 12 weeks numerically improved A1C and significantly improved A1C goal attainment, PPG, and body weight. Sotagliflozin plus insulin was generally well tolerated without any episodes of DKA (NCT02383940).

Project description:<h4>Objective</h4>To assess the efficacy and safety of dual sodium glucose cotransporter (SGLT) 1/2 inhibitor sotagliflozin in type 1 diabetes mellitus.<h4>Design</h4>Meta-analysis of randomised controlled trials.<h4>Data sources</h4>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.<h4>Eligibility criteria for selecting studies</h4>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.<h4>Results</h4>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.<h4>Conclusions</h4>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.

Project description:<h4>Objective</h4>Evaluate the effect of sotagliflozin, a dual inhibitor of sodium glucose cotransporter (SGLT) 1 and 2, on arterial stiffness in patients with type 1 diabetes (T1D) treated with sotagliflozin as adjunct to optimized insulin therapy.<h4>Methods</h4>In this post hoc analysis, indirect markers of arterial stiffness, including pulse pressure, mean arterial pressure (MAP), and double product, were calculated using observed systolic blood pressure (SBP), diastolic blood pressure (DBP), or pulse rate at 24 weeks using data from a pooled patient population from the inTandem1 and inTandem2 randomized controlled trials (<i>n</i> = 1575).<h4>Results</h4>Baseline characteristics were similar among groups. Relative to placebo at Week 24, sotagliflozin 200 mg and 400 mg reduced SBP by 2.03 mm Hg (95% CI -3.30 to -0.75; <i>p</i> = 0.0019) and 2.85 mm Hg (-4.12 to -1.57; <i>p</i> < 0.0001), respectively. DBP decreased by 1.1 and 0.9 mm Hg, MAP by 1.4 and 1.6 mm Hg, and double product by 202.5 and 221.1 bpm × mm Hg, respectively (<i>p</i> < 0.05 for all). No increases in heart rate were observed.<h4>Conclusion</h4>In adults with T1D, adding sotagliflozin to insulin significantly reduced blood pressure and other markers of arterial stiffness and vascular resistance.

Project description:OBJECTIVE:To assess the safety and efficacy of dual sodium-glucose cotransporter (SGLT) 1 and SGLT2 inhibition with sotagliflozin as adjunct therapy to insulin in type 1 diabetes. RESEARCH DESIGN AND METHODS:We treated 33 patients with sotagliflozin, an oral dual SGLT1 and SGLT2 inhibitor, or placebo in a randomized, double-blind trial assessing safety, insulin dose, glycemic control, and other metabolic parameters over 29 days of treatment. RESULTS:In the sotagliflozin-treated group, the percent reduction from baseline in the primary end point of bolus insulin dose was 32.1% (P = 0.007), accompanied by lower mean daily glucose measured by continuous glucose monitoring (CGM) of 148.8 mg/dL (8.3 mmol/L) (P = 0.010) and a reduction of 0.55% (5.9 mmol/mol) (P = 0.002) in HbA1c compared with the placebo group that showed 6.4% reduction in bolus insulin dose, a mean daily glucose of 170.3 mg/dL (9.5 mmol/L), and a decrease of 0.06% (0.65 mmol/mol) in HbA1c. The percentage of time in target glucose range 70-180 mg/dL (3.9-10.0 mmol/L) increased from baseline with sotagliflozin compared with placebo, to 68.2% vs. 54.0% (P = 0.003), while the percentage of time in hyperglycemic range >180 mg/dL (10.0 mmol/L) decreased from baseline, to 25.0% vs. 40.2% (P = 0.002), for sotagliflozin and placebo, respectively. Body weight decreased (1.7 kg) with sotagliflozin compared with a 0.5 kg gain (P = 0.005) in the placebo group. CONCLUSIONS:As adjunct to insulin, dual SGLT1 and SGLT2 inhibition with sotagliflozin improved glycemic control and the CGM profile with bolus insulin dose reduction, weight loss, and no increased hypoglycemia in type 1 diabetes.

Project description:<h4>Introduction</h4>This randomized, double-blind, placebo-controlled, single and multiple ascending-dose study evaluated the pharmacodynamic effects and safety/tolerability of canagliflozin, a sodium glucose co-transporter 2 inhibitor, in patients with type 2 diabetes.<h4>Methods</h4>Patients (N?=?116) discontinued their antihyperglycemic medications 2 weeks before randomization. Patients received canagliflozin 30, 100, 200, or 400 mg once daily or 300 mg twice daily, or placebo at 2 study centers in the United States and Germany, or canagliflozin 30 mg once daily or placebo at 1 study center in Korea, while maintaining an isocaloric diet for 2 weeks. On Days -1, 1, and 16, urinary glucose excretion (UGE), plasma glucose (PG), fasting PG (FPG), and insulin were measured. The renal threshold for glucose (RTG) was calculated from UGE, PG, and estimated glomerular filtration rate. Safety was evaluated based on adverse event (AE) reports, vital signs, electrocardiograms, clinical laboratory tests, and physical examinations.<h4>Results</h4>Canagliflozin increased UGE dose-dependently (?80-120 g/day with canagliflozin ?100 mg), with increases maintained over the 14-day dosing period with each dose. Canagliflozin dose-dependently decreased RTG, with maximal reductions to ?4-5 mM (72-90 mg/dL). Canagliflozin also reduced FPG and 24-hour mean PG; glucose reductions were seen on Day 1 and maintained over 2 weeks. Plasma insulin reductions with canagliflozin were consistent with observed PG reductions. Canagliflozin also reduced body weight. AEs were transient, mild to moderate in intensity, and balanced across groups; 1 canagliflozin-treated female reported an episode of vaginal candidiasis. Canagliflozin did not cause hypoglycemia, consistent with the RTG values remaining above the hypoglycemia threshold. At Day 16, there were no clinically meaningful changes in urine volume, urine electrolyte excretion, renal function, or routine laboratory test values.<h4>Conclusions</h4>Canagliflozin increased UGE and decreased RTG, leading to reductions in PG, insulin, and body weight, and was generally well tolerated in patients with type 2 diabetes.<h4>Trial registration</h4>ClinicalTrials.gov NCT00963768.

Project description:AIMS:To compare the pharmacodynamic effects of the highest approved doses of the sodium glucose co-transporter 2 (SGLT2) inhibitors canagliflozin and dapagliflozin on urinary glucose excretion (UGE), renal threshold for glucose excretion (RTG ) and postprandial plasma glucose (PPG) excursion in healthy participants in a randomized, double-blind, two-period crossover study. METHODS:In each treatment period, participants (n?=?54) received canagliflozin 300?mg or dapagliflozin 10?mg for 4?days (20?min before breakfast). A mixed-meal tolerance test (600?kcal; 75?g glucose) was performed at baseline and on day 4 of each treatment period to assess changes in incremental PPG (PPG?AUC0-2 h ). We measured 24-h UGE and plasma glucose on day 4 to determine 24-h mean RTG . RESULTS:Canagliflozin 300?mg and dapagliflozin 10?mg had similar effects on UGE and RTG for 4?h after dosing, but canagliflozin was associated with higher UGE and greater RTG reductions for the remainder of the day. Mean 24-h UGE was ?25% higher with canagliflozin than with dapagliflozin (51.4 vs. 40.8?g), and 24-h mean RTG was ?0.4 mmol/l (7 mg/dl) lower with canagliflozin than with dapagliflozin (3.79 vs. 4.17 mmol/l; p?<?0.0001). Dapagliflozin had no effect on PPG excursion; canagliflozin delayed and reduced PPG excursion (between-treatment difference in PPG?AUC0-2 h from baseline expressed as a percentage of baseline mean, -10.2%; p?=?0.0122). Canagliflozin and dapagliflozin were generally well tolerated. CONCLUSIONS:In healthy participants, canagliflozin 300?mg provided greater 24-h UGE, a lower RTG and smaller PPG excursions than dapagliflozin 10?mg.
