MO047STABLE EGFR IN PATIENTS WITH PRIMARY HYPEROXALURIA TYPE 1 TREATED WITH LUMASIRAN, REGARDLESS OF KIDNEY FUNCTION AT START OF TREATMENT

Abstract Background and Aims Primary hyperoxaluria type 1 (PH1) is a rare genetic disorder characterized by hepatic oxalate overproduction. Excess oxalate is excreted by the kidneys, leading to recurrent kidney stones, nephrocalcinosis, and progressive kidney disease. Patients with PH1 generally experience a slow decline in kidney function over time that can be punctuated by abrupt worsening precipitated by infection, obstructing stones, or dehydration. Approximately half of patients with PH1 progress to kidney failure by early adulthood, and nearly all by 60 years of age. Lumasiran is an RNAi therapeutic indicated for the treatment of PH1 in all age groups. In clinical trials, treatment with lumasiran resulted in substantial reductions in urinary and plasma oxalate in pediatric and adult patients, with an acceptable safety profile. This analysis evaluates the change in kidney function of patients with PH1 with an eGFR of ≥30 mL/min/1.73m2 enrolled in clinical trials of lumasiran. Method We analyzed kidney function from 75 patients with PH1, age ≥12 months old, eGFR ≥30 mL/min/1.73m2, enrolled in 3 clinical trials of lumasiran (Phase 2 open-label extension, and Phase 3 ILLUMINATE-A and ILLUMINATE-B). In these trials, eGFR was calculated with the Modification of Diet in Renal Disease (MDRD) Study equation in adults or the bedside Schwartz equation in children. The effect of lumasiran on eGFR was assessed by baseline eGFR subgroup: ≥90, <90, 60 to <90, 45 to <60, and 30 to <45 mL/min/1.73m2. Results Of 75 patients available for analysis, 46 were treated with lumasiran from the start of the study through the Month 12 visit. eGFR remained stable in all eGFR subgroups. Patients with eGFR ≥90 mL/min/1.73m2 at baseline (N=16) demonstrated fluctuations in mean values by timepoint, with a mean change (95% CI) from baseline of -1 (-8, 6) mL/min/1.73m2 at Month 12. In patients with eGFR <90 mL/min/1.73m2 (N=30), no change in mean eGFR from baseline was observed at Month 12; the mean change (95% CI) was 0 (-3, 3). When evaluating subgroups with impaired kidney function, variations in the mean change were observed at Month 12 due to small sample sizes. For patients with eGFR 60 to <90 mL/min/1.73m2 (N=22), the mean change (95% CI) was -2 (-5, 1). For patients with eGFR 45 to <60 mL/min/1.73m2 (N=5), the mean change (95% CI) was 3 (-8, 14). For patients with eGFR 30 to <45 mL/min/1.73m2 (N=3), the mean change (95% CI) was 9 (7, 11). Conclusion Patients with PH1 had stable kidney function over time with lumasiran treatment, regardless of kidney function at baseline. Given the progressive kidney function decline that is characteristic of PH1, the eGFR stability observed during 12 months of treatment with lumasiran is encouraging. Kidney function will continue to be monitored for the duration of the lumasiran clinical trials.

Безопасность и эффективность ипраглифлозина у пациентов из Японии с сахарным диабетом 2-го типа и нарушением функции почек: анализ в подгруппах 3-летнего постмаркетингового наблюдательного исследования (STELLA-LONG TERM)

STELLA-LONG TERM, a 3-year post-marketing surveillance study, evaluated the safety and effectiveness of the sodiumglucose cotransporter 2 inhibitor ipragliflozin in Japanese type 2 diabetes mellitus (T2DM) patients. Final results in the safety (n = 6697) and effectiveness populations (n = 5625) were analyzed by stratifying patients by baseline estimated glomerular filtration rate (eGFR, mL/min/1.73 m 2 ) into four subgroups (≥90, 60 to <90, 45 to <60, and <45) and two subgroups (≥60 and <60). Adverse drug reaction (ADR) incidence, and changes from baseline in glycosylated hemoglobin (HbA 1c ), bodyweight, and eGFR were assessed. The percentage of patients experiencing ADRs and serious ADRs was similar across most eGFR subgroups. Polyuria/pollakiuria was the most common ADR. Renal disorders and volume depletion ADRs were more frequent in the subgroups with more severe renal impairment at baseline than in those with an eGFR of 60 to <90 or ≥90 mL/min/1.73 m 2 . Bodyweight and HbA1c decreased in all subgroups, the latter by − 0.91% to − 0.40% (P <0.05 vs. baseline). eGFR increased in the 45 to <60 mL/min/1.73 m 2 subgroup (+ 1.42 ± 8.77 mL/min/1.73 m 2 ; P = 0.006). It decreased in the ≥90 and 60 to <90 mL/min/1.73 m 2 subgroups (− 8.27 ± 13.73 and − 1.22 ± 10.34 mL/min/1.73 m 2 ; P <0.001), but not to <60 mL/min/1.73 m 2 . In conclusion, there were no new or unexpected safety findings in Japanese patients treated with ipragliflozin for T2DM, and long-term sustained improvements in HbA 1c and bodyweight were observed regardless of the presence of renal impairment.

Glycaemic Control with Insulin Glargine 300U/mL in Individuals with Type2 Diabetes and Chronic Kidney Disease: A REALI European Pooled Data Analysis.

IntroductionManagement of type 2 diabetes mellitus (T2DM) in patients with chronic kidney disease is complex. Using the REALI European pooled database, we determined the impact of baseline renal function on the effectiveness and safety of insulin glargine 300 U/mL (Gla-300) initiated in adults with inadequately controlled T2DM.MethodsData from 1712 patients with available estimated glomerular filtration rate (eGFR) at baseline were pooled from six 24-week prospective studies. Patients who received once-daily subcutaneous injections of Gla-300 were classified into four renal function subgroups, according to baseline eGFR: ≥ 90 (N = 599), 60–89 (N = 786), 45–59 (N = 219), and 15–44 mL/min/1.73 m2 (N = 108).ResultsCompared to those with baseline eGFR ≥ 60 mL/min/1.73 m2, patients with lower eGFR values tended to be older, had a longer T2DM duration, and were more likely to present diabetic complications. After 24 weeks of Gla-300 therapy, the least-squares mean (95% confidence interval) decrease in haemoglobin A1c (HbA1c) from baseline (− 1.14% [− 1.28 to − 1.00], − 1.21% [− 1.34 to − 1.08], − 1.19% [− 1.36 to − 1.01], and − 0.99% [− 1.22 to − 0.76]) and the proportion of patients achieving HbA1c < 7.5% (53.3%, 51.3%, 49.5%, and 51.5%) were comparable in the ≥ 90, 60–89, 45–59, and 15–44 mL/min/1.73 m2 subgroups, respectively. Although the incidence of hypoglycaemia was overall low, more patients in the eGFR 15–44 mL/min/1.73 m2 subgroup experienced hypoglycaemia at night or at any time of the day compared with higher eGFR subgroups. There were no notable differences between the renal function subgroups in the changes in Gla-300 daily dose and body weight from baseline to week 24.ConclusionAlthough an eGFR of 15–44 mL/min/1.73 m2 was associated with a slightly increased risk of hypoglycaemia among patients with inadequately controlled T2DM, Gla-300 provided glycaemic improvement with an overall favourable safety profile regardless of baseline eGFR.

Patiromer and Spironolactone in Resistant Hypertension and Advanced CKD: Analysis of the Randomized AMBER Trial.

Mineralocorticoid receptor antagonists reduce mortality in patients with heart failure with reduced ejection fraction and have become a standard of care in those with resistant hypertension (rHTN). Yet, their use is limited among patients with CKD, primarily due to hyperkalemia. AMBER was a multicenter, randomized, double-blind, placebo-controlled, parallel-group study that reported that the use of the potassium-binding drug patiromer allowed a more persistent use of spironolactone in patients with CKD and rHTN. In this report, we compare the safety and efficacy of patiromer in advanced CKD as a prespecified analysis. Of the 295 patients randomized, 66 fell into the eGFR 25 to <30 subgroup. In this subgroup, persistent use of spironolactone was seen in 19 of 34 (56%) in the placebo group and 27 of 32 (84%) in the patiromer group (absolute difference 29%; P<0.02). In the eGFR 30-45 subgroup, persistent use of spironolactone was seen in 79 of 114 (69%) in the placebo group and 99 of 115 (86%) in the patiromer group (absolute difference 17%; P=0.003). There was no significant interaction between eGFR subgroups (P=0.46). Systolic BP reduction with spironolactone in the eGFR 25 to <30 subgroup was 6-7 mm Hg; in the eGFR 30-45 subgroup, it was 12-13 mm Hg. There was no significant interaction between eGFR subgroups on BP reduction (P=0.79). Similar proportions of patients reported adverse events (59% in the eGFR 25 to <30 subgroup; 53% in the eGFR 30-45 subgroup). Patiromer facilitates the use of spironolactone among patients with rHTN, and its efficacy and safety are comparable in those with eGFR 25 to <30 and 30-45 ml/min per 1.73 m2.

Associations of serum bisphenol A levels with incident chronic kidney disease risk

Associations of bisphenol A (BPA) levels with renal disease are inconsistent. The present prospective study aims to evaluate the association of serum BPA levels with chronic kidney disease (CKD) in a Chinese middle-aged and elderly population. At baseline 1370 participants (mean age 61.7 years, 58.8% females) free of kidney disease and cancer were followed up nearly 10 years. Baseline serum BPA concentration was measured with high-performance liquid chromatography-tandem mass spectrometry (HPLC-MS). Estimated glomerular filtration rate (eGFR) was calculated using the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equation. Multivariable logistic regression model was used to investigate relationship between serum BPA levels and incident CKD risk. During a 10-year follow-up, 246 individuals developed CKD. Baseline serum BPA concentration was 2.92 (1.00, 5.27) ng/mL. At baseline, after adjustment for multiple covariates serum BPA levels were negatively correlated with eGFR levels (β = −0.068, P = 0.009). Compared to those with low levels of serum BPA, participants with high levels had a significant negative association with CKD [ORs (95% CI) = 0.35 (0.25, 0.50), P < 0.001], and this association was not modified by conventional risk factors. The negative associations remained in females but not in males (P for interaction = 0.016). Significant interaction between baseline eGFR and serum BPA levels on CKD risk was also found (P for interaction = 0.027), Except subjects with 60–70 mL/min/1.73 m2 eGFR at baseline, inverse association robustly existed between serum BPA levels and incident CKD risk in the other eGFR subgroups. Further studies are needed to validate our findings.

Risk of hypoglycemia in Japanese people with type 2 diabetes mellitus who initiated or switched to insulin glargine 300 U/mL: A subgroup analysis of 12-month post-marketing surveillance study (X-STAR study)

AimsThis study investigated the hypoglycemia risk in people with type 2 diabetes (T2D) who initiated or switched to insulin glargine 300 U/mL (Gla-300) by stratifying them by age and renal function. MethodsWe examined data from 4621 people with T2D (1227 insulin-naïve and 3394 insulin-experienced) of the X-STAR study, a prospective, observational, 12-month study conducted from December 2015 to August 2018 in Japan. Participants were stratified by age (<65, 65 to <75, and ≥75 years) and estimated glomerular filtration rate (eGFR) (≥90, 60 to <90, 30 to <60, and <30 mL/min/1.73 m2). Hypoglycemia was defined according to the Ministry of Health, Labour and Welfare manual of Japan. ResultsNo apparent increase in the proportion of people who experienced hypoglycemia was found in all subgroups. The proportions were 2.9–3.5% and 2.7–5.2% of insulin-naïve and insulin-experienced people, respectively, for age subgroups, and 2.4–4.7% and 4.6–4.8%, respectively, for eGFR subgroups. The result was similar for HbA1c levels below and at or above 7.0% in all age subgroups. ConclusionsOur study found no apparent increase in the hypoglycemia risk in people with older age and renal impairment who were administered Gla-300. These results would provide reassuring information on Gla-300 use.

Safety and effectiveness of ipragliflozin in Japanese patients with type 2 diabetes mellitus and impaired renal function: subgroup analysis of a 3-year post-marketing surveillance study (STELLA-LONG TERM).

STELLA-LONG TERM, a 3-year post-marketing surveillance study, evaluated the safety and effectiveness of the sodium-glucose cotransporter 2 inhibitor ipragliflozin in Japanese type 2 diabetes mellitus (T2DM) patients. Final results in the safety (n = 6697) and effectiveness populations (n = 5625) were analyzed by stratifying patients by baseline estimated glomerular filtration rate (eGFR, mL/min/1.73m2) into four subgroups (≥ 90, 60 to < 90, 45 to < 60, and < 45) and two subgroups (≥ 60 and < 60). Adverse drug reaction (ADR) incidence, and changes from baseline in glycosylated hemoglobin (HbA1c), bodyweight, and eGFR were assessed. The percentage of patients experiencing ADRs and serious ADRs was similar across most eGFR subgroups. Polyuria/pollakiuria was the most common ADR. Renal disorders and volume depletion ADRs were more frequent in the subgroups with more severe renal impairment at baseline than in those with an eGFR of 60 to < 90 or ≥ 90mL/min/1.73m2. Bodyweight and HbA1c decreased in all subgroups, the latter by -0.91% to -0.40% (P < 0.05 vs. baseline). eGFR increased in the 45 to < 60mL/min/1.73m2 subgroup (+ 1.42 ± 8.77mL/min/1.73m2; P = 0.006). It decreased in the ≥ 90 and 60 to < 90mL/min/1.73m2 subgroups (-8.27 ± 13.73 and -1.22 ± 10.34mL/min/1.73m2; P < 0.001), but not to < 60mL/min/1.73m2. In conclusion, there were no new or unexpected safety findings in Japanese patients treated with ipragliflozin for T2DM, and long-term sustained improvements in HbA1c and bodyweight were observed regardless of the presence of renal impairment.

Denosumab Safety and Efficacy Among Participants in the FREEDOM Extension Study With Mild to Moderate Chronic Kidney Disease.

ContextThe effects of long-term exposure to denosumab in individuals with renal insufficiency are unknown.ObjectiveThis post hoc analysis evaluates the long-term safety and efficacy of denosumab in individuals with mild-to-moderate chronic kidney disease (CKD) (stages 2 and 3) using data from the pivotal phase 3, double-blind, 3-year FREEDOM (NCT00089791) and open-label, 7-year extension (NCT00523341) studies.Participants and MethodsWomen age 60 to 90 years with a bone mineral density (BMD) T-score of less than –2.5 to greater than –4.0 at the total hip or lumbar spine were randomly assigned 1:1 to receive denosumab 60 mg subcutaneously every 6 months (long-term arm) or placebo (cross-over arm) in FREEDOM; eligible participants could enroll in the extension to receive denosumab 60 mg subcutaneously every 6 months. Change in estimated glomerular filtration rate (eGFR) from study baseline and annualized rates of fracture and adverse events (AEs) were the main outcome measures.ResultsMost participants (1259/1969 [64%] long-term arm; 1173/1781 [66%] crossover arm) with baseline CKD stage 2 or 3 remained within the same CKD subgroup at study completion; less than 3% progressed to CKD stage 4. Participants in all eGFR subgroups showed similar, persistent BMD gains over time and a low incidence of fractures. The percentage of participants reporting serious AEs was similar among renal subgroups (normal, CKD stage 2, CKD stage 3a, CKD stage 3b) both for the long-term (54% vs 52% vs 57% vs 58%) and crossover (43% vs 42% vs 43% vs 68%) arms, except CKD stage 3b subgroup, crossover arm.ConclusionThe safety and efficacy of denosumab did not differ among participants with mild to moderate CKD.

Efficacy and safety of dronedarone vs placebo in patients with atrial fibrillation or atrial flutter across a spectrum of renal function: post hoc analyses of the EURIDIS-ADONIS trials

Abstract Background/Introduction The use of antiarrhythmic drugs in patients with chronic kidney disease (CKD) is complex because impaired renal clearance can cause increased drug levels, and risk of intolerance or adverse events. Since CKD commonly co-occurs with atrial fibrillation/atrial flutter (AF/AFL), it is important to establish efficacy and safety for such drugs when used in AF/AFL patients with CKD. Purpose To evaluate the efficacy and safety of dronedarone in patients with AF or AFL across different levels of renal function. Methods This post hoc analysis evaluated pooled data from two multicentre, double-blind, randomised (2:1) trials of rhythm control with dronedarone 400 mg twice daily vs placebo. Primary endpoint was time to first recurrence of AF or AFL. Renal function (estimated glomerular filtration rate [eGFR]) was assessed with the CKD-Epidemiology Collaboration equation. Patients were grouped by eGFR strata. Log-rank testing and Cox regression were used to compare time to events between treatment groups. Results Most (85%) patients had mild or mild-to-moderate decrease in eGFR (Table 1). Median time to first AF recurrence was significantly longer in the dronedarone vs placebo group for all eGFR subgroups except the 30–44 mL/min group (Figure 1), where the trend was consistent; however, the small population size may have precluded meaningful analyses in this subgroup. Serious adverse events, deaths, and treatment discontinuations did not differ notably between each group irrespective of eGFR strata. Conclusions This analysis confirms the efficacy and safety of dronedarone in patients with AF across a wide spectrum of renal function.

Cardiac and Kidney Benefits of Empagliflozin in Heart Failure Across the Spectrum of Kidney Function: Insights From EMPEROR-Reduced.

In EMPEROR-Reduced (Empagliflozin Outcome Trial in Patients With Chronic Heart Failure With Reduced Ejection Fraction), empagliflozin reduced cardiovascular death or heart failure (HF) hospitalization and total HF hospitalizations, and slowed the progressive decline in kidney function in patients with HF and a reduced ejection fraction, with and without diabetes. We aim to study the effect of empagliflozin on cardiovascular and kidney outcomes across the spectrum of kidney function. In this prespecified analysis, patients were categorized by the presence or absence of chronic kidney disease (CKD) at baseline (estimated glomerular filtration rate [eGFR] <60 ml/min/1.73 m2 or albumin-to-creatine ratio >300 mg/g). The primary and key secondary outcomes were: (1) a composite of cardiovascular death or HF hospitalization (primary outcome); (2) total HF hospitalizations; and (3) eGFR slope. The direct impact on kidney events was investigated by a prespecified composite kidney outcome (defined as a sustained profound decline in eGFR, chronic dialysis, or transplant). The median follow-up was 16 months. Of 3730 patients who were randomized to empagliflozin or placebo, 1978 (53%) had CKD. Empagliflozin reduced the primary outcome and total HF hospitalizations in patients with and without CKD: hazard ratio (HR)=0.78 (95% CI, 0.65-0.93) and HR=0.72 (95% CI, 0.58-0.90), respectively (interaction P=0.63). Empagliflozin slowed the slope of eGFR decline by 1.11 (0.23-1.98) ml/min/1.73 m2/yr in patients with CKD and by 2.41 (1.49-3.32) ml/min/1.73 m2/yr in patients without CKD. The risk of the composite kidney outcome was reduced similarly in patients with and without CKD: HR=0.53 (95% CI, 0.31-0.91) and HR=0.46 (95% CI, 0.22-0.99), respectively. The effect of empagliflozin on the primary composite outcome and key secondary outcomes was consistent across a broad range of baseline kidney function, measured by clinically relevant eGFR subgroups or by albuminuria, including patients with eGFR as low as 20 ml/min/1.73 m2. Empagliflozin was well tolerated in CKD patients. In EMPEROR-Reduced, empagliflozin had a beneficial effect on the key efficacy outcomes and slowed the rate of kidney function decline in patients with and without CKD, and regardless of the severity of kidney impairment at baseline.

Cardiovascular and renal outcomes by baseline albuminuria status and renal function: Results from the LEADER randomized trial.

AimTo assess cardiorenal outcomes by baseline urinary albumin‐to‐creatinine ratio (UACR) and estimated glomerular filtration rate (eGFR) in the contemporary LEADER cohort.Materials and methodsLEADER was a multinational, double‐blind trial. Patients with type 2 diabetes and high cardiovascular (CV) risk were randomized 1:1 to the glucagon‐like peptide‐1 analogue liraglutide (≤1.8 mg daily; n = 4668) or placebo (n = 4672) plus standard care and followed for 3.5 to 5 years. Primary composite outcomes were time to first non‐fatal myocardial infarction, non‐fatal stroke or CV death. Post hoc Cox regression analyses of outcomes by baseline UACR and eGFR subgroups were conducted with adjustment for baseline variables.ResultsIn the LEADER population, 1598 (17.5%), 2917 (31.9%), 1200 (13.1%), 1611 (17.6%), 845 (9.2%) and 966 (10.6%) had UACR = 0, >0 to <15, 15 to <30, 30 to <100, 100 to <300 and ≥300 mg/g, respectively. Increasing UACR and decreasing eGFR were linked with higher risks of the primary outcome, heart failure hospitalization, a composite renal outcome and death (P‐values for the Cochran‐Armitage test for trends were all <.0001). Across UACR and eGFR subgroups, risks of cardiorenal events and death were generally lower or similar with liraglutide versus placebo.ConclusionsIn a contemporary type 2 diabetes population, increasing baseline UACR and declining eGFR were linked with higher risks of cardiorenal events and death.

1021-P: HbA1c Levels and Rates of Hypoglycemia with Insulin Degludec U200 and Insulin Glargine U300 Stratified by Renal Function Subgroups: Post Hoc Analysis from the CONCLUDE Trial

CONCLUDE was a randomized, open-label, treat-to-target trial in participants with T2D, who received basal insulin ± oral antihyperglycemic drugs (OADs) and had ≥1 baseline hypoglycemia risk factors, including moderate renal impairment. Participants were randomized to degludec U200 or glargine U300 (± OADs). CONCLUDE demonstrated no significant difference in the overall symptomatic hypoglycemia rate with degludec U200 vs. glargine U300 in the maintenance period (primary endpoint, tested for superiority). However, lower rates of nocturnal symptomatic and severe hypoglycemia in the maintenance period (exploratory secondary endpoints) were observed with degludec U200 vs. glargine U300. The current post-hoc analysis investigated these hypoglycemia endpoints and HbA1c stratified by baseline estimated glomerular filtration rate (eGFR) subgroups (&amp;lt;60, 60-&amp;lt;90, ≥90 mL/min/1.73 m2). Change in HbA1c from baseline to end of treatment and rates and rate ratios for all hypoglycemia endpoints were comparable across eGFR subgroups and to the primary analyses. No statistically significant interactions were found between the subgroups for the endpoints assessed (Table). Irrespective of renal function, degludec U200 and glargine U300 resulted in similar HbA1c, and hypoglycemia rates were consistent with the primary analyses. Disclosure T.R.

119-LB: Metformin Prescriptions in Chronic Kidney Disease Patients after the Revised FDA Recommendations in 2016

Background: In 2016, metformin’s prescribing label was revised to permit it to be started with estimated glomerular filtration rate (eGFR) 45-60 ml/min and continued with eGFR 30-44 ml/min. We examined whether subsequent metformin prescribing in these groups increased. Methods: We conducted an interrupted time series study using data from the New York City Clinical Data Research Network. We identified episodes from 2014-2017 in which adult patients with HbA1c ≥6.5% received outpatient antidiabetic prescriptions ≤7 days after an eGFR measurement. Trends in the proportion of episodes that included metformin were examined using linear regression in 4 eGFR subgroups: ≥60 (reference), 45-59, 30-44, and &amp;lt;30 ml/min. Sensitivity analysis examined episodes with no antidiabetic prescription in the prior 180 days. Results: We identified 10,608 prescribing episodes among 6,505 patients. Lower eGFR was associated with less metformin prescribing. In the eGFR 30-44 ml/min group, there were significant increases in metformin prescribing after the label change (p&amp;lt;0.001). In sensitivity analysis, an increasing trend in metformin prescriptions in the 45-59 ml/min eGFR group started before the label change (p=0.04) and leveled off. Conclusion: Metformin prescribing for patients with eGFR 30-60 ml/min was increasing prior to the label change. Rates of metformin use at eGFR 30-45 ml/min remain relatively low. Disclosure J.

1100-P: Efficacy and Safety of Sotagliflozin by Baseline Renal Function in Adults with Type 1 Diabetes

Many adults with T1D are not at glycemic goal and are overweight or obese and this trend appears to be worsening. SGLT inhibitors have been shown to improve metabolic outcomes in T1D. However, the glycemic efficacy of selective SGLT2 inhibitors depends on the amount of glucose filtered in the glomerulus and as such efficacy attenuates as renal function declines. The mechanism of action of sotagliflozin (SOTA) involves inhibition of SGLT2 in the kidney and SGLT1 in the gastrointestinal tract. This post-hoc analysis evaluated the efficacy and safety of SOTA by baseline eGFR (45-&amp;lt;60 [N = 71]; 60-&amp;lt;90 [N = 774]; ≥90 mL/min/1.73 m² [N = 730]) using pooled results in 1575 adults with T1D from the inTandem1 and 2 studies. Baseline A1C and body weight (BW) were not different among groups and baseline systolic blood pressure (SBP) tended to be higher in those with eGFR&amp;lt;60 mL/min/1.73 m². Placebo-adjusted reduction in A1C and BW at Week 24 with SOTA was consistent across eGFR subgroups (Table). The safety profile of SOTA was consistent with results published for entire population, with a higher incidence of DKA and a lower incidence of severe hypoglycemia for sotagliflozin vs. placebo. There was no increase in renal-related adverse events or acute kidney injury with SOTA. The efficacy and safety profile of SOTA was generally similar across adults with T1D and varying degrees of renal function. Disclosure Y.

P0706THE EFFECT OF NON-VITAMIN K ANTAGONIST ORAL ANTICOAGULANTS ON RENAL OUTCOMES IN PATIENTS WITH NON-VALVULAR ATRIAL FIBRILLATION

Abstract Background and Aims Lifelong oral anticoagulation (either with warfarin or a non–vitamin K antagonist oral anticoagulant (NOACs)) is indicated for stroke prevention in most patients with atrial fibrillation (AF). NOACs has been recommended for thromboembolism prophylaxis of nonvalvular AF. However, studies on the impact of NOACs on renal outcomes has been inconclusive. Method This retrospective cohort study compared 3 NOACs: apixaban, dabigatran and rivaroxaban to warfarin for their effects on renal outcomes in patients with nonvalvular AF who had been using these medications for at least 2 years as of 2017-2018. The primary outcome was either the incidence of &amp;gt; 30% decline in estimated glomerular filtration rate (eGFR) or doubling of the serum creatinine levels compare to baseline values at 24 months, and the secondary outcome was the incident of primary outcomes in different baseline eGFR subgroups (&amp;gt; 60 vs &amp;lt; 60 ml/min/1.73 m2) and major bleeding as an adverse event. Results 90 patients were enrolled in each group, totaling to 360 patients. The incidence of &amp;gt; 30% decline in eGFR is significantly higher in rivaroxaban compared to warfarin (hazard ratio: 2.09; 95% confidence interval: 1.35 to 3.24; p = 0.001). After multivariate analysis (using age, stage of chronic kidney disease, eGFR, CHAD2VAS and HASBLED score), dabigatran was also shown to significantly increase the incidence of &amp;gt; 30% decline in eGFR. In subgroup analysis, rivaroxaban resulted in higher incidence of &amp;gt; 30% decline in eGFR, in eGFR &amp;lt; 60 ml/min/1.73 m2 subgroup and higher incidence of doubling of the serum creatinine level in eGFR &amp;gt; 60 ml/min/1.73 m2 subgroup. There was no occurrence of major bleeding. Conclusion NOACs, especially rivaroxaban, may increase adverse renal outcomes in patients with nonvalvular AF.

Differential glycaemic control with basal insulin glargine 300 U/mL versus degludec 100 U/mL according to kidney function in type 2 diabetes: A subanalysis from the BRIGHT trial.

AimsChronic kidney disease (CKD) challenges diabetes management and is associated with increased cardiovascular morbidity and mortality. We examined whether clinical outcomes with insulin glargine 300 U/mL (Gla‐300) and insulin degludec 100 U/mL (IDeg‐100) are affected by renal function in a prespecified subgroup analysis from the BRIGHT trial.Materials and methodsBRIGHT (NCT02738151) was a multicentre, open‐label, randomized, active‐controlled, two‐arm, parallel‐group, 24‐week study in insulin‐naïve uncontrolled type 2 diabetes (T2D). Participants were randomized 1:1 to evening Gla‐300 (n = 466) or IDeg‐100 (n = 463) and stratified based on baseline estimated glomerular filtration rate (eGFR) for this analysis.ResultsHeterogeneity of treatment effect across renal function subgroups was observed (P = .02), reflecting a greater mean glycated haemoglobin (HbA1c) reduction from baseline to week 24 with Gla‐300 versus IDeg‐100 in the eGFR <60 mL/min/1.73 m2 subgroup (least squares mean difference: −0.43% [95% confidence interval: −0.74% to −0.12%]), while there were no differences in hypoglycaemia incidence or rates over 24 weeks in that subgroup. HbA1c reductions were similar between treatments in the other eGFR subgroups. However, heterogeneity was observed for annualized rates of anytime (24 hours) or nocturnal (00:00‐05:59 hours) confirmed hypoglycaemia (≤70 mg/dL [≤3.9 mmol/L]) over 24 weeks showing less hypoglycaemia with Gla‐300 versus IDeg‐100 in the ≥90 mL/min/1.73 m2.ConclusionsKidney function seems to affect the glucose‐lowering effects of Gla‐300 versus IDeg‐100 in insulin‐naïve T2D. Greater HbA1c reductions with Gla‐300 without increase in hypoglycaemia risk, were observed in patients with eGFR <60 mL/min/1.73 m2.

SGLT2 inhibitors for the prevention of kidney failure in patients with type 2 diabetes: a systematic review and meta-analysis

The effects of sodium-glucose co-transporter-2 (SGLT2) inhibitors on kidney failure, particularly the need for dialysis or transplantation or death due to kidney disease, is uncertain. Additionally, previous studies have been underpowered to robustly assess heterogeneity of effects on kidney outcomes by different levels of estimated glomerular filtration rate (eGFR) and albuminuria. We aimed to do a systematic review and meta-analysis to assess the effects of SGLT2 inhibitors on major kidney outcomes in patients with type 2 diabetes and to determine the consistency of effect size across trials and different levels of eGFR and albuminuria. We did a systematic review and meta-analysis of randomised, controlled, cardiovascular or kidney outcome trials of SGLT2 inhibitors that reported effects on major kidney outcomes in people with type 2 diabetes. We searched MEDLINE and Embase from database inception to June 14, 2019, to identify eligible trials. The primary outcome was a composite of dialysis, transplantation, or death due to kidney disease. We used random-effects models to obtain summary relative risks (RRs) with 95% CIs and random-effects meta-regression to explore effect modification by subgroups of baseline eGFR, albuminuria, and use of renin-angiotensin system (RAS) blockade. This review is registered with PROSPERO (CRD42019131774). From 2085 records identified, four studies met our inclusion criteria, assessing three SGLT2 inhibitors: empagliflozin (EMPA-REG OUTCOME), canagliflozin (CANVAS Program and CREDENCE), and dapagliflozin (DECLARE-TIMI 58). From a total of 38 723 participants, 252 required dialysis or transplantation or died of kidney disease, 335 developed end-stage kidney disease, and 943 had acute kidney injury. SGLT2 inhibitors substantially reduced the risk of dialysis, transplantation, or death due to kidney disease (RR 0·67, 95% CI 0·52-0·86, p=0·0019), an effect consistent across studies (I2=0%, pheterogeneity=0·53). SGLT2 inhibitors also reduced end-stage kidney disease (0·65, 0·53-0·81, p<0·0001), and acute kidney injury (0·75, 0·66-0·85, p<0·0001), with consistent benefits across studies. Although we identified some evidence that the proportional effect of SGLT2 inhibitors might attenuate with declining kidney function (ptrend=0·073), there was clear, separate evidence of benefit for all eGFR subgroups, including for participants with a baseline eGFR 30-45 mL/min per 1·73 m2 (RR 0·70, 95% CI 0·54-0·91, p=0·0080). Renoprotection was also consistent across studies irrespective of baseline albuminuria (ptrend=0·66) and use of RAS blockade (pheterogeneity=0·31). SGLT2 inhibitors reduced the risk of dialysis, transplantation, or death due to kidney disease in individuals with type 2 diabetes and provided protection against acute kidney injury. These data provide substantive evidence supporting the use of SGLT2 inhibitors to prevent major kidney outcomes in people with type 2 diabetes. None.

Safety and effectiveness of tofogliflozin in Japanese patients with type2 diabetes mellitus in real-world practice: Results of 12-month interim analysis of a long-term post-marketing surveillance study (J-STEP/LT).

Aims/IntroductionDue to the paucity of tofogliflozin data, we assessed the safety and effectiveness of tofogliflozin among Japanese patients with type 2 diabetes mellitus in the clinical setting, stratifying the patients by age, sex, estimated glomerular filtration (eGFR) rate and body mass index. We report the results of a 12‐month interim analysis.Materials and MethodsThis was a 3‐year prospective, observational and multicenter post‐marketing study (Japanese Study of tofogliflozin with type 2 diabetes mellitus Patients/Long Term).ResultsOut of 6,897 patients enrolled, the safety and effectiveness analysis populations consisted of 6,712 and 6,449 patients, respectively. During 12 months, adverse drug reactions and their incidence were 9.12 and 0.88%, respectively. The incidence of hypoglycemia was 0.67%. Polyuria/pollakiuria occurred more frequently in patients aged ≥65 years than in patients aged <65 years. Women experienced higher rates of urinary tract and genital infection than men. The lowest eGFR subgroup experienced maximum volume depletion‐related events. Cardiovascular and cerebrovascular disorders occurred in 0.55% of the patients. Glycated hemoglobin (HbA1c) and bodyweight significantly decreased by −0.76% and −2.73 kg, respectively, from baseline to the last observation carried forward (P < 0.0001). Except for the lowest eGFR subgroup, other eGFR subgroups showed significantly decreased HbA1c values. All eGFR subgroups showed significantly decreased bodyweight, and all body mass index subgroups showed significantly decreased HbA1c and bodyweight.ConclusionsOur interim 12‐month data suggest that tofogliflozin could be used safely and effectively in Japanese patients with type 2 diabetes mellitus, as tofogliflozin was well tolerated with low hypoglycemia risk, and significantly improved HbA1c and bodyweight.

The renoprotective effects of sodium-glucose cotransporter 2 inhibitors versus placebo in patients with type 2 diabetes with or without prevalent kidney disease: A systematic review and meta-analysis.

We undertook a systematic review and meta-analysis to assess the efficacy and safety of sodium-glucose cotransporter 2 inhibitors (SGLT2is) concerning kidney outcomes in patients with type 2 diabetes mellitus (T2DM), with or without prevalent kidney disease. PubMed, Web of science, Embase and the Cochrane Library were systematically searched for randomized controlled trials (RCTs) to assess the efficacy and safety of treatment with SGLT2is versus placebo in patients with T2DM. The weighted mean difference (WMD) and its 95% confidence interval (CI) were applied for continuous variables, and the risk ratio (RR) and corresponding 95% CI were used for dichotomous outcomes. Patients were categorized according to whether the baseline mean estimated glomerular filtration rate (eGFR) was less or was more than 60 mL/min/1.73 m2 . A total of 25 eligible studies with 43 721 participants were included. There was an initial and small decrease in eGFR during the early treatment period (WMD, -4.63; 95% CI, -6.08 to -3.19 mL/min/1.73 m2 ), which was noted at 1-6 weeks and gradually narrowed over time, with a decline in protection from eGFR in the long term (WMD, 3.82; 95% CI, 2.80-4.85 mL/min/1.73 m2 ). SGLT2is significantly delayed albuminuria progression (RR, 0.71; 95% CI, 0.66-0.76), promoted albuminuria regression (RR,1.71; 95% CI, 1.54-1.90), improved the composite of ≥40% decrease in eGFR, in the need for renal-replacement and in death from renal causes (RR, 0.57; 95% CI, 0.49-0.66), and reduced all-cause mortality (RR, 0.84; 95% CI, 0.75-0.94). At the same time, they significantly increased the risk of genital infection (RR, 3.43; 95% CI, 2.87-4.10) vs placebo in patients with T2DM. Meta-regression analyses showed that eGFR-preservation effects were not significantly associated with basic patient characteristics (age, BMI, HbA1c, eGFR level), but were influenced by drug administration (treatment duration, type, dosage of SGLT2is). Subgroup analyses showed that the relative effects on renal outcomes of SGLT2is vs placebo were similar across eGFR subgroups (P heterogeneity >0.05). SGLT2is slowed eGFR decline, lowered albuminuria progression, improved adverse renal endpoints and reduced all-cause mortality, but increased risk of genital infections vs placebo in patients with T2DM. The indication of consistent renal benefits across categories of baseline eGFR levels may allow additional individuals to benefit from SGLT2is therapy.

Effects of Liraglutide Versus Placebo on Cardiovascular Events in Patients With Type 2 Diabetes Mellitus and Chronic Kidney Disease.

LEADER trial (Liraglutide Effect and Action in Diabetes: Evaluation of CV Outcome Results) results demonstrated cardiovascular benefits for patients with type 2 diabetes mellitus at high cardiovascular risk on standard of care randomized to liraglutide versus placebo. The effect of glucagon-like peptide-1 receptor agonist liraglutide on cardiovascular events and all-cause mortality in patients with type 2 diabetes mellitus and chronic kidney disease is unknown. Liraglutide's treatment effects in patients with and without kidney disease were analyzed post hoc. Patients were randomized (1:1) to liraglutide or placebo, both in addition to standard of care. These analyses assessed outcomes stratified by baseline estimated glomerular filtration rate (eGFR; <60 versus ≥60 mL/min/1.73 m2) and baseline albuminuria. The primary outcome (composite of cardiovascular death, nonfatal myocardial infarction, or nonfatal stroke) and secondary outcomes, including all-cause mortality and individual components of the primary composite outcome, were analyzed using Cox regression. Overall, 2158 and 7182 patients had baseline eGFR <60 or ≥60 mL/min/1.73 m2, respectively. In patients with eGFR <60 mL/min/1.73 m2, risk reduction for the primary composite cardiovascular outcome with liraglutide was greater (hazard ratio [HR], 0.69; 95% CI, 0.57-0.85) versus those with eGFR ≥60 mL/min/1.73 m2 (HR, 0.94; 95% CI, 0.83-1.07; interaction P=0.01). There was no consistent effect modification with liraglutide across finer eGFR subgroups (interaction P=0.13) and when analyzing eGFR as a continuous variable (interaction P=0.61). Risk reductions in those with eGFR <60 versus ≥60 mL/min/1.73 m2 were as follows: for nonfatal myocardial infarction, HR, 0.74; 95% CI, 0.55-0.99 versus HR, 0.93; 95% CI, 0.77-1.13; for nonfatal stroke, HR, 0.51; 95% CI, 0.33-0.80 versus HR, 1.07; 95% CI, 0.84-1.37; for cardiovascular death, HR, 0.67; 95% CI, 0.50-0.90 versus HR, 0.84; 95% CI, 0.67-1.05; for all-cause mortality, HR, 0.74; 95% CI, 0.60-0.92 versus HR, 0.90; 95% CI, 0.75-1.07. Risk reduction for the primary composite cardiovascular outcome was not different for those with versus without baseline albuminuria (HR, 0.83; 95% CI, 0.71-0.97; and HR, 0.92; 95% CI, 0.79-1.07, respectively; interaction P=0.36). Liraglutide added to standard of care reduced the risk for major cardiovascular events and all-cause mortality in patients with type 2 diabetes mellitus and chronic kidney disease. These results appear to apply across the chronic kidney disease spectrum enrolled. URL: https://www.clinicaltrials.gov/ . Unique identifier: NCT01179048.
