Diabetic Kidney Disease: New Pathways New Treatment
Sympo 13
DECLARE as the largest and broadest CVOT in the SGLT-2i class to date has defined the cardio-renal benefit of dapagliflozin for patients with T2DM
• The DECLARE trial confirms in a broad patient population with good renal function over 4.2 years follow up that dapagliflozin is both renal- and cardio-protective
• DECLARE met its primary endpoint of reduction in hHF/CV death across the entire study population
• Dapagliflozin also demonstrated significant reduction in the prespecified composite secondary renal endpoint, sustained eGFR decrease of >40% to <60mL/min/1.73m2, ESRD, renal or CV death (nominally significant) in a large (n=17,160) and broad population of patients with T2DM and good baseline renal function (mean eGFR of 85.2mL/min/1.73m2). This benefit was demonstrated across eGFR subgroupsand in patients with both eCVD and MRFs
• Both increased albuminuria and declining eGFR are associated with increased CV mortality and risk of renal failure2. There is currently limited therapies to treat diabetic kidney disease and preventing new onset or worsening of diabetic kidney disease progression represents a significant opportunity to reduce both mortality and morbidity of patients with T2DM.
• Diabetic kidney disease is a major contributor to the CKD and renal replacement therapy burden globally3. The use of dapagliflozin early in patients with T2DM will not only control the patient’s HbA1c but also prevent renal disease progression and CV events.

• A 2010 report estimated 2.6 million people
were receiving RRT1
• This same report suggested that
~5 million actually required RRT1
• The number receiving RRT is estimated to
increase to more than 5 million by 20301
• This rise is largely driven by population
ageing and an increasing prevalence of
diabetes and hypertension1
• Diabetes accounts for 30%-50% of all CKD2
• The number of adults with diabetes is
projected to grow from 425 million in 2017 to
to over 600 million by the year 20453

Therefore renal and cardiac systems and outcomes should be considered together

Glomerular hyperfiltration is well characterized in early diabetes
13
T2D = type 2 diabetes; TGF = tubuloglomerular feedback.
Alicic RZ et al. Clin J Am Soc Nephrol. 2017;12:2032-2045.
• Glomerular hyperfiltration, a consequence
of early diabetes, leads to glomerular
hypertension
• It is observed in up to 40% of patients with
T2D
• Decreased distal delivery of sodium to the
macula densa leads to a decrease in TGF
and dilates the afferent arteriole to
increase glomerular pressure
• Concurrently, high local production of
angiotensin II at the efferent arteriole
produces vasoconstriction
• The overall effect is high intraglomerular
pressure and glomerular hyperfiltration
Normal Diabetes
SGLT2 inhibition has a number of potential direct and downstream effects which may result in improved renal structural architecture and function
14
Na = sodium; SGLT2 = sodium–glucose co-transporter 2; TGF = tubuloglomerular feedback.
Heerspink HJL et al. Kidney Int. 2018;94:26-39.
Tubuloglomerular feedback restoration:
• Inhibits proximal glucose reabsorption
• Blocks proximal sodium reabsorption
• Leads to natriuresis and increased
Na delivery to the macula densa
• TGF constricts the afferent arteriole, resulting in
decreased glomerular hyperfiltration
Additional downstream effects:
• Decreased urinary albumin excretion may reduce
pro-inflammatory pathway activation and direct
tubular toxicity
• Improved cardiac function and increased
hematocrit concentration may result in increased
oxygen delivery to the kidney and improvements in
renal hypoxia

• In December 2008, the US Food and Drug Administration (FDA) issued new guidance describing an enhanced strategy for ensuring the CV safety of drugs marketed for the management of diabetes1
• Three SGLT2i studies have reported1
• In addition to assessing CV safety, impact on renal outcomes was also investigated1,2
18
The 2018 ADA-EASD T2D consensus report reflects emerging evidence from GLP-1 RA and SGLT2i CVOTs in patients with established CVD or CKD
CONSENSUS RECOMMENDATIONS
Patients with T2D who have established
ASCVD:
SGLT2 inhibitors or GLP-1 RAs with proven
CV benefit recommended
Patients with ASCVD in whom HF coexists
or is of special concern:
SGLT2 inhibitors recommended
Patients with T2D and CKD, with or
without CVD:
Consider SGLT2 inhibitor or, if
contraindicated/not preferred, GLP-1 RA
shown to reduce CKD progression

• Diabetes accounts for 30%-50% of all CKD. The number of adults with diabetes is projected to grow from 425 million in 2017 to to over 600 million by the year 2045.
• The renal complication of diabetes occur early with over 25% of patients having microalbuminuria at time of diagnosis
• Renal and CV disease are connected. Worsening renal function adversely impact CV outcomes. CV diseases like heart failure worsen renal function.
• HF occurred more commonly than MI or CV death in diabetic kidney disease trials
• DECLARE assessed dapagliflozin’s CV and renal outcomes in a broad population of T2D. Patients enrolled in DECLARE were early in their CV risk continuum and had better preserved renal function compared to previous SGLT2i studies assessing the ability of dapagliflozin to demonstrate organ protection.
• DECLARE results showed that dapagliflozin reduced the composite of hHF/CV death by 17% and reduced a renal only composite endpoint by 47% (nominal p value). This benefit was consistent across baseline renal function subgroups.
• Dapagliflozin, when given to patients with preserved renal function and at lower CV risk demonstrate both cardiac and renal protection
