Abstract: SGLT2 inhibitors may lead to short term decrease in eGFR, with later stabilization and long-term reduction in the risk for end stage kidney disease. Fast decline (FD) in eGFR can be defined as a reduction of ≥3 ml/min/1.73m2/year and is associated with poor long-term renal prognosis. In this post-hoc analysis we studied the effect of dapagliflozin (dapa) on the risk for FD in the DECLARE-TIMI 58 trial. In DECLARE-TIMI 58, 17,160 patients with T2D and established or increased risk for CVD, with mean baseline eGFR of 85.2 ml/min/1.73m2, were randomized to dapa vs. placebo and followed for a median of 4.2 years. The risk for FD was compared between treatment arms. In the time frame of 0.5 years (after stabilization) to 4 years, the proportion of patients with FD was reduced with dapa vs. placebo (26.8% vs. 37.1% respectively, p & lt;0.0001). This observation was persistent in all subgroups assessed (Table). The mean (SD) reduction in eGFR per year was 6.3 (3.7) vs. 0.0 (2.5) ml/min/1.73m2/year in the FD (N=4,788) vs. non-FD (N=10,224) patients. The proportion of patients with FD during the entire study period (i.e., 0-4 years) was reduced with dapa vs. placebo as well (33.6% vs. 37.0% respectively, p & lt;0.0001). Dapagliflozin reduced the risk for FD in eGFR in a broad population of patients with T2D and either established or increased risk for CVD, but relatively preserved renal function, irrespective of patients’ baseline characteristics.

Abstract: Tirzepatide (TZP, 5, 10, 15 mg/week) , a dual GIP/GLP-1 receptor agonist, reduced HbA1c levels more than titrated daily insulin glargine (iGlar) in people inadequately controlled on oral diabetes treatments with type 2 diabetes (T2D) and high cardiovascular risk (median study duration 85 weeks) . Here, we compared progression to pre-specified kidney endpoints between TZP and iGlar. Composite kidney outcomes in SURPASS-4 were analysed: endpoint 1 (eGFR [CKD-EPI] decline ≥40% from baseline, renal death, progression to ESRD, new onset macroalbuminuria) and endpoint 2 (endpoint 1 without new onset macroalbuminuria) . Data were examined within the entire study population, and in subgroups defined by baseline SGLT2i use, UACR ≥30 mg/g, eGFR & lt;60 mL/min/1.73m2 and in those at high risk for kidney related outcomes, defined as eGFR & lt;75 mL/min per 1.73 m2 and macroalbuminuria, or eGFR & lt;45 mL/min per 1.73 m2. At baseline, participants (N=1995, age 63.6 years, HbA1c, 8.5%) had a mean eGFR of 81.3 mL/min per 1.73 m2; 17% had eGFR & lt;60 mL/min per 1.73 m2, 28% microalbuminuria (UACR 30-300 mg/g) and 8% macroalbuminuria (UACR & gt;300 mg/g) . During the follow-up to 1weeks, TZP participants experienced significantly fewer renal outcomes, especially new onset of macroalbuminuria versus iGlar (Table) . In people with T2D and high cardiovascular risk, TZP reduced markers of diabetic kidney disease risk.

Abstract: The basis for the more aggressive loss of β-cell function in youth-onset type 2 diabetes (Y-T2D) compared to adult-onset T2D and its unresponsiveness to interventions remain incompletely understood. Given the increasing incidence of Y-T2D, there is an urgent need to better understand its pathophysiology and develop appropriate interventions. Accordingly, we sought to identify multiprotein signatures that predict loss of glycemic control in Y-T2D. We measured 7604 Aptamers in 374 baseline plasma samples from the Treatment Options for type 2 Diabetes in Adolescents and Youth (TODAY) study, using the SomaScan 7K Proteomic (SomaLogic) platform. Loss of glycemic control was defined as HbA1c ≥8% for 6 months or inability to wean from temporary insulin after acute metabolic decompensation. We evaluated associations with time to loss of glycemic control in Cox proportional hazards models adjusted for body mass index (BMI) and estimated insulin sensitivity. Gene set enrichment analysis identified pathways of interest. The false discovery rate was controlled at 5% and we report q-values. Participants were 14±2 years of age, 37% male; 72% experienced loss of glycemic control. Seventy-four proteins were associated with time to loss of glycemic control, with sixty-seven proteins remaining associated with time to loss of glycemic control after multivariable adjustments, such as: plexin-B2 (HR: 1.54 per 1 SD [95% CI 1.35, 1.76], q & lt;0.0001) and Ephrin-A3 (HR: 1.25 [1.13, 1.39], q=0.012). Twenty gene sets, including HIF-1 signaling, metabolic and cell adhesion pathways, were positively related and 13 gene sets were negatively related to time to loss of glycemic control. Novel proteins, including those involved in regulation of insulin secretion and ligand-receptor pairing in β-cells, predict loss of glycemic control in Y-T2D, independently of BMI and estimated insulin sensitivity. Future work should include validation of these findings and investigating potential therapeutic targets. Disclosure T.B.Vigers: None.

Abstract: The decline of estimated glomerular filtration rate (eGFR) in patients with type 2 diabetes is variable, and early interventions would likely be cost-effective. We elucidated the contribution of 17 plasma biomarkers to the prediction of eGFR loss on top of clinical risk factors. RESEARCH DESIGN AND METHODS We studied participants in PROVALID (PROspective cohort study in patients with type 2 diabetes mellitus for VALIDation of biomarkers), a prospective multinational cohort study of patients with type 2 diabetes and a follow-up of more than 24 months (n = 2,560; baseline median eGFR, 84 mL/min/1.73 m2; urine albumin-to-creatinine ratio, 8.1 mg/g). The 17 biomarkers were measured at baseline in 481 samples using Luminex and ELISA. The prediction of eGFR decline was evaluated by linear mixed modeling. RESULTS In univariable analyses, 9 of the 17 markers showed significant differences in median concentration between stable and fast-progressing patients. A linear mixed model for eGFR obtained by variable selection exhibited an adjusted R2 of 62%. A panel of 12 biomarkers was selected by the procedure and accounted for 34% of the total explained variability, of which 32% was due to 5 markers. The individual contribution of each biomarker to the prediction of eGFR decline on top of clinical predictors was generally low. When included into the model, baseline eGFR exhibited the largest explained variability of eGFR decline (R2 of 79%), and the contribution of each biomarker dropped below 1%. CONCLUSIONS In this longitudinal study of patients with type 2 diabetes and maintained eGFR at baseline, 12 of the 17 candidate biomarkers were associated with eGFR decline, but their predictive power was low.

Abstract: Introduction: Canagliflozin (CANA) slows progression of kidney disease, which may be at least partly mediated by improvements in tubular function. To test this hypothesis, we assessed effects of CANA on markers of tubular function and injury in the CANVAS trial. Methods: Urine biomarkers of tubule function (β2-microglobulin [B2M], cystatin C, and uromodulin), tubular injury (interleukin-18 [IL-18] , kidney injury molecule-1 [KIM-1], neutrophil gelatinase associated lipocalin [NGAL] , and osteopontin), and inflammation (monocyte chemotactic protein-1 [MCP-1]) were measured at baseline and after 12 months. Biomarker concentrations were standardized for urine creatinine concentration. Differences between CANA and placebo treatment were assessed using ANCOVA models. Results: We included 3723 CANVAS participants with available urine samples (eGFR 77.1 ml/min/1.73 m2 and median UACR 11.7 mg/g). Clinical characteristics and biomarker levels were well balanced between treatment groups at baseline. CANA compared to placebo significantly reduced urinary KIM-1, uromodulin, cystatin C, and osteopontin. It did not change NGAL or MCP-1 and increased IL-18 and B2M. Results were consistent in subgroups by baseline UACR except MCP-1, which decreased in patients with UACR ≥30 mg/g (Table). Conclusion: CANA had variable effects on markers of tubule cell injury and function, decreasing 4, while 2 remained stable and 2 increased. Disclosure T. Sen: None. J.

Abstract: Background: Diabetic kidney disease (DKD) develops by young adulthood in up to 50% of people with youth-onset type 2 diabetes (Y-T2D), increasing risk of dialysis and premature death. Understanding mechanisms responsible for early DKD is key to management and prevention; accordingly, we sought to identify metabolite signatures of DKD in Y-T2D. Methods: We measured 57 metabolites in 374 baseline plasma and urine samples from the Treatment Options for type 2 Diabetes in Adolescents and Youth (TODAY) study, using mass spectrometry with a targeted ZipChip based assay. Urine albumin-to-creatinine ratio (UACR) was assessed annually for up to 15 years. Incident moderate and severe albuminuria were defined as UACR ≥30 and ≥300 mg/g, respectively, on ≥2 of 3 measures. We evaluated prediction of moderate and severe albuminuria in separate Cox proportional hazards models adjusted for HbA1c, triglycerides, systolic blood pressure, and estimated insulin sensitivity. Urine metabolites were normalized by urine creatinine. Results: Participants were 14±2 years of age, 37% male; 43% developed either moderate or severe albuminuria. Four urine metabolites predicted time to moderate albuminuria, while 8 urine metabolites predicted time to severe albuminuria, with 3 metabolites in common: 2-hydroxybutyric acid (moderate: HR: 0.82 per 1 SD [95% CI 0.70, 0.96] ; severe: 0.70 [0.55, 0.88]), glycine (moderate: 0.81 [0.69, 0.94] ; severe: 0.62 [0.45, 0.85]), citric acid (moderate: 0.78 [0.67, 0.91] ; severe: 0.76 [0.58, 0.99]). Four plasma metabolites predicted time to moderate albuminuria and severe albuminuria, such as glutamic acid for moderate albuminuria (1.23 [1.03, 1.47] ) and citric acid for severe albuminuria (1.39 [1.09, 1.77]). Conclusion: Higher urine metabolites involved in mitigating oxidative stress (glycine), glomerular epithelial cell injury (2-hydroxybutyric acid) and preserving mitochondrial function (citrate) predicted lower risk of albuminuria in Y-T2D.

Abstract: Background: Sodium-glucose co-transporter-2 inhibitors were previously shown to improve renal parameters. In this predefined analysis of DECLARE-TIMI 58, we report the effects of dapagliflozin (dapa) on albuminuria in a broad population of patients with type 2 diabetes (T2DM) and either multiple risk factors (MRF) for or atherosclerotic cardiovascular disease (ASCVD), according to patients’ baseline albuminuria status. Methods: We randomized 17,160 patients with T2DM and either MRF 10,186 (59%) or ASCVD 6974 (41%) to dapa 10 mg or placebo in addition to standard of care, including 13,950 (81%) patients on ACEI/ARB. We report urinary albumin-to-creatinine ratio (UACR) change over the median follow-up of 4 years for dapa vs. placebo, according to albuminuria at baseline. Results: At baseline there were 11,644 (69%) patients w/normo-albuminuria (UACR & lt;30 mg/g), 4,030 (24%) w/microalbuminuria (UACR ≥30 to ≤300 mg/g); and 1,169 (7%) w/macroalbuminuria (UACR & gt;300 mg/g). Dapa blunted the increase in UACR over time by -29.0 mg/g (95% CI -44.0, -14.0; P=0.0002). This benefit was observed in patients with normo-, micro-, and macro-albuminuria: 3.2 mg/g (95% CI -6.4 to 0.03; P=0.052), -51.3 mg/g (95% CI -67.6 to -35.1; P & lt;0.0001) and 262.3 mg/g (95% CI -480.7 to -43.9; P=0.019), respectively. Dapa also significantly increased the likelihood that patients improved from micro to normo-albuminuria (hazard ratio [HR] 1.35, 95% CI [1.24, 1.47] ; p & lt;.0001) and from macro to micro or normo-albuminuria (HR 1.55, 95% CI [1.34, 1.8]; p & lt;.0001). Dapa decreased the likelihood that patients deteriorated from normo to micro or macroalbuminuria (HR 0.84, 95% CI [0.79, 0.89]; p & lt;.0001). Conclusion: In a broad population of patients with T2DM, long-term treatment with dapagliflozin blunts the rise in urinary albumin excretion, in all stratum of baseline albuminuria. Disclosure I.

Abstract: Introduction: Growth differentiation factor 15 (GDF-15) is a marker of inflammation and cellular injury. Small clinical studies have suggested that SGLT2 inhibitors exert anti-inflammatory effects. We examined the association of baseline GDF-15 with kidney outcomes in patients with type 2 diabetes mellitus (T2DM) participating in the CANagliflozin cardioVascular Assessment Study (CANVAS) study. We also assessed the effect of the SGLT2 inhibitor canagliflozin (CANA) on GDF-15. Methods: The CANVAS trial randomized 4330 people with T2DM at high cardiovascular risk to CANA or placebo. Plasma GDF-15 concentration was measured with GDF-15 Roche Elecsys assay at baseline and follow-up. The association between GDF-15 and the primary kidney outcome (40% eGFR decline, end-stage kidney disease, or renal death) was assessed using multivariable adjusted Cox regression. Linear mixed effects models were used to assess the effect of CANA versus placebo on GDF-15 levels. Results: We included 3557 CANVAS participants with available plasma samples (mean age 62.8 years, 33.1% female, mean eGFR 76.9 ml/min/1.73 m2, median uACR 11.6 mg/g, median GDF-15 1776.0 pg/ml). During a mean follow-up of 5.7 years, 137 kidney outcomes occurred. Higher GDF-15 levels were independently associated with higher risk of kidney events (HR 1.98 [95% CI 1.40 to 2.81] per log increment GDF-15). Treatment with CANA modestly lowered GDF-15 compared to placebo (-2% [95% CI -5 to 0; p=0.046] ). The effect of CANA on the kidney outcome (HR 0.56, 95% CI 0.40-0.79) was consistent regardless of baseline GDF-15 levels (p-interaction=0.75). GDF-15 did however not mediate the renal protective effect of CANA (percent mediation 3.9% [95% CI -3.6 to 14.0]). Conclusion: CANA modestly lowers GDF-15, which is independently associated with a higher risk of kidney disease progression in patients with T2DM at high cardiovascular risk. The modest reduction in GDF-15 with CANA did not mediate the renal protective effect of CANA. Disclosure J. Li: Employee; Self; George Institute. T. Sen: None. B.

Abstract: We aimed to identify metabolites that predict the loss of glycemic control in youth-onset T2D (Y-T2D), a disease characterized by more rapid decline in β-cell function than adults-onset T2D. The increasing incidence of Y-T2D highlights the need to understand its pathophysiology and develop appropriate interventions. We measured 40 plasma metabolites in 374 baseline and 10-year follow-up samples from the Treatment Options for type 2 Diabetes in Adolescents and Youth (TODAY) study, using mass spectrometry with a targeted ZipChip based assay. Loss of glycemic control was defined as HbA1c ≥8% for 6 months or inability to wean from temporary insulin after acute metabolic decompensation. We evaluated associations with time to loss of glycemic control in Cox proportional hazards models adjusted for HbA1c, triglycerides, systolic blood pressure, and estimated insulin sensitivity. Participants were 14±2 years of age, 63% female; 72% experienced loss of glycemic control. Five baseline plasma metabolites (threonine, asparagine, glycine, glutamine, L-alpha-aminobutyrate) associated with lower risk of loss of glycemic control, and one baseline plasma metabolite (citrate) associated with higher risk of loss of glycemic control. After multivariable adjustments, only plasma citrate remained statistically significant (HR: 1.16 per 1 SD [95% CI 1.04, 1.30]). At 10-year follow-up, of these plasma metabolites only threonine (logFC: -0.28, p=3.8×10-11) and glycine (logFC: -0.17, p=5.7×10-5) were significantly lower. Plasma metabolites, such as citrate that might originate from an excess of fatty acids, predicted loss of glycemic control in youth with T2D. Future work should validate these findings and investigate their response to promising therapies.

Abstract: KidneyIntelX is a composite risk score incorporating biomarkers and clinical variables for predicting progression of prevalent diabetic kidney disease (DKD). The change of this score over time in response to SGLT2 inhibitors and how these changes associate with future kidney outcomes is unknown. We measured soluble Tumor Necrosis Factor Receptor 1 (sTNFR-1), soluble Tumor Necrosis Factor Receptor 2 (sTNFR-2), and Kidney Injury Molecule (KIM-1) on banked samples from CANVAS trial participants with baseline DKD (eGFR & lt;60 ml/min/1.73 m2 or UACR ≥30 mg/mg) and determined the KidneyIntelX risk score at baseline and year 1. We assessed the effect of canagliflozin (CANA) on KidneyIntelX scores and how changes from baseline to year 1 were associated with subsequent DKD progression (composite outcome of eGFR decline of ≥5 ml/min/year [using 6-week eGFR as baseline in the CANA group], ≥40% sustained decline in eGFR, or kidney failure). There were 1016 participants with prevalent DKD who had baseline and year 1 plasma samples. Median age was 64 years, 30% were female, median eGFR was 66 ml/min and median UACR was 55 mg/g. After year 1, 68 (6.7%) participants experienced the composite outcome over a median of 4.9 years. CANA reduced KidneyIntelX risk by 5.1% (95% CI -6.6 to -3.6) at year 1 vs. increasing by 5.8% (95% CI 3.4 to 8.1) in placebo (p & lt;0.001). Each percent reduction in KidneyIntelX score at year 1 was associated with a 2% lower risk of the composite outcome (OR per unit 0.98, 95% CI 0.97 to 0.99; p & lt;0.001) after adjusting for baseline score and treatment arm. The associations between the change in KidneyIntelX and outcome were consistent in the treatment arm and placebo arm (pinteraction=0.63). In conclusion, CANA treatment reduced KidneyIntelX risk scores. Changes in the KidneyIntelX score from baseline to 1 year predict future risk of DKD progression whether they resulted from kidney protection afforded by SGLT2i therapy, or decline in kidney function caused by disease progression.
