HYPERKALAEMIA challenge in CKD

Hyperkalaemia is a highly prevalent condition in your patients with chronic kidney disease¹ and can jeopardise their beneficial RAASi therapy^2,3

RAASi therapy is vital

Progression of CKD to kidney failure, the avoidance or delay in initiating dialysis therapy, and the risks associated with dialysis are critically important to patients.⁴

RAASi have been shown to slow kidney function decline more effectively than other blood pressure-lowering drugs and to reduce proteinuria.^4-6

RAASi are the cornerstone of therapy in CKD, and their use at the highest tolerated dose is recommended by multiple organisations^4,7

Two landmark trials (IDNT⁸: Irbesartan Diabetic Nephropathy Trial and RENAAL⁹: Reduction of Endpoints in NIDDM with the Angiotensin II Antagonist Losartan) were conducted in patients with T2DM and CKD with albuminuria >1 g/d.
The renoprotective effect of these drugs was evidenced by a
16–20% reduction in the composite endpoint of risk of death, progression to dialysis or doubling for serum creatinine.^4,8,9
Ramipril use in patients with non-diabetic nephropathy has also been shown to have a renoprotective effect, reducing both proteinuria and the rate of GFR decline.¹⁰

HYPERKALAEMIA risk is exacerbated by RAASi

Guideline-directed use of RAASi has been cited as a major factor in the development of hyperkalaemia in patients with CKD.¹¹

In clinical trials, RAASi have been shown to increase the risk of hyperkalaemia in patients with CKD.¹²
Real-world studies consistently show an approximate 1.5-fold increased risk of hyperkalaemia in patients on RAASi,^13,14 with risk increasing with severity of kidney disease.¹⁵

Proportion of patients with hyperkalaemia during the first year of therapy with RAASi increases with severity of kidney disease¹⁵

HYPERKALAEMIA leads to suboptimal RAASi use

Current guidelines recommend dose reduction or discontinuation of RAASi if persistent hyperkalaemia is a problem in patients with CKD. As a result, hyperkalaemia is one of the main reasons for withholding RAASi treatment.^2,3

In a large US database analysis,² ~40% and ~50% of patients on maximum RAASi dose experiencing mild or moderate-to-severe hyperkalaemia, respectively, had their dose reduced or stopped after a hyperkalaemic event.

Nearly half of patients on maximal RAASi dose have their treatment reduced or stopped after a hyperkalaemia event²

Mild hyperkalaemia: 38% of CKD patients stop/reduce RAASi post HK event

Nearly half of patients on maximal RAASi dose have their treatment reduced or stopped after a hyperkalaemia event²

Moderate/severe hyperkalaemia: 47% of CKD patients stop/reduce RAASi

However, reducing or stopping RAASi is associated with an increased risk of mortality and morbidity.^2,16

Physicians, therefore, are often faced with the dilemma of using RAASi and accepting hyperkalaemia or reducing/stopping RAASi and accepting poorer clinical outcomes

What is needed is a therapy that allows CKD patients to stay on beneficial RAASi therapy with reliable long-term control of serum K⁺ levels.

Mortality risk doubles when RAASi is reduced or stopped²

Current treatment options for chronic HYPERKALAEMIA are limited

Both short- and long-term treatment strategies are critical for the management of hyperkalaemia.¹⁷However, currently available options focus mainly on emergency and intermediate care,¹⁷ and there are substantial limitations associated with current treatment options for chronic hyperkalaemia:

Dietary modifications may lead to restricted consumption of healthy foods,¹⁸ and it may be very difficult for patients already on a restricted diet to adhere to further dietary modifications.^19,20 The effects of dietary interventions on outcomes are uncertain.¹⁹

Non-K⁺-sparing loop diuretics depend on residual renal function and are associated with increased risk of gout and diabetes, volume contraction and reduced potassium excretion, and sarcopenia.^17,21

Traditional K⁺-binders (SPS and CPS) can be associated with life-threatening GI side effects and hypokalaemia^22,23and may not be suitable in those who cannot tolerate an increase in sodium (SPS).²³

There is an unmet need for a reliable long-term option for the management of chronic hyperkalaemia that enables patients to continue RAASi therapy at target doses.¹⁷
