Filter by:This study aim to describe hyperkalemia clinical burden and investigate the risk factors associated with the burden on HD facility level.
Background: CKD in patients with heart failure (HF) is common and associated with poor prognosis. Despite evidence of benefit with Renin-Angiotensin-Aldosterone-System inhibitor (RAASi) agents, they are avoided due to fear of hyperkalaemia. New potassium binders, e.g. Sodium Zirconium Cyclosilicate (SZC), reduce incidence of hyperkalaemia in CKD-HF patients and hence may help RAASi maximisation, which has not been investigated in an RCT. Purpose: The proposed study will randomise HFrEF patients with stable CKD 3-5 and serum potassium 5-5.0 mmol/L, to receive SZC or placebo while RAASi therapy is maximised. The aim of the study is to examine if SZC is superior to placebo in achieving maximal doses of ACEi/ARB, e.g. Ramipril 10 mg, Candesartan 32 mg; and mineralocorticoid receptor antagonist, e.g. Epleronone 50 mg or Spironolactone 50 mg, avoiding hyperkalaemia. Methods: Eligible patients with eGFR<60 mL/min/1.73m2, heart failure (EF<40%) on none/submaximal dose of RAASi will be randomised to receive 10g TDS of investigational medicinal product (IMP), either SZC or placebo, for 48 hours and in 10 or 5g OD guided by laboratory serum potassium (K+). Every two weeks the RAASi dose will be increased and IMP adjusted according to a strict protocol and guided by laboratory potassium and creatinine. The primary endpoint of the study is achievement of maximal dose of RAASi in randomised patients avoiding hyperkalaemia, i.e. K+≤5.6 mmol/L. Patients will be allowed to continue with RAASi maximisation to K+<6.0mmol/L. Patients will be tested at baseline and follow-up visits for hyperkalaemia, AKI, symptomatic hypotension and QT prolongation on ECG. Results: The study results will show if SZC is superior to placebo for RAASi maximisation in CKD-HF patients while maintaining safe levels of serum potassium without any adverse impact on quality of life. The study will demonstrate if SZC allows higher RAASi dose and more dose escalations than placebo. It will also examine the impact of RAASi escalation on creatinine, proteinuria, and cardiac blood biomarkers. Conclusion: If positive, the results of this study will demonstrate that SZC enables RAASi up titration in CKD-HF patients, which potentially can help achieve optimal treatment and improve quality of life of the patient.
Prescribing Sodium zirconium cyclosilicate (SZC) with enhanced nutritional advice to participants with hyperkalaemia on haemodialysis will reduce serum K+ (S-K+ ) and enable the consumption of more fruit and vegetables and more satisfying diet. The study aims to show that participants using SZC achieve S-K+ reduction as well as participants on SoC (other than K+ binders), without the need for restricting K+ in the diet.
The hypothesis is that 3 months' treatment with SZC versus placebo will enable RASi (Irbesartan) maximisation in a cohort of patients with diabetic kidney disease.
The purpose of this study is to evaluate the superiority of ZG-801 to placebo in Japanese hyperkalemia patients whose serum potassium value becomes normal in the Run-in period by comparing the change in the value at the Double-blind period week 4, and to further evaluate the efficacy and safety of ZG-801 in Japanese hyperkalemia patients administrated ZG-801 for maximum 9 weeks.
The CARE-HK in HF is a registry study based on the hypothesis that adherence to guidelines is associated with improved real-world outcomes for heart failure (HF) patients. For the purpose of this study, adherence to guidelines is defined as adherence to RAASi treatment recommendations, according to the AHA/ACC and ESC guidelines. Objectives relating to patiromer effectiveness will only be evaluated if a sufficient number of patients are available. The study aims to evaluate in patients at high risk of hyperkalaemia; patients treated with ACEi/ARB/ARNi, and either treated with or candidates for treatment with MRA.
The purpose of this study is to evaluate the effect of Sodium Zirconium Cyclosilicate (SZC) on arrhythmia-related cardiovascular outcomes in participants on chronic hemodialysis with recurrent hyperkalemia.
The objective of this study is to evaluate the prevalence and recurrence of Hyperkalaemia (HK) in Chinese HD patients and to understand the treatment pattern of HK in China.
Mineralocorticoid receptor antagonists (MRA) is one of cornerstones in the treatment of heart failure with reduced ejection fraction (HFrEF). However, MRA has been extremely under-used globally. The main reason for this seems to be increased risk of hyperkalemia in individuals on MRA. Theoretically, by limiting the risk of hyperkalemia it could thus be possible to optimize MRA therapy. This is studied in this randomized controlled trial in which it is investigated whethere adding a potassium-binder in combination with MRA treatment prevent hyperkalemia to a greater extent than only using MRA. The specific aim of this study is to demonstrate the efficacy and safety of Sodium Zirconium Cyclosilicate (SZC) in optimizing MRA in symptomatic patients with HFrEF. A multicenter, randomized, placebo-controlled, double-blinded study in Sweden (n=110) The study consists of 2 phases: 1) open-label run-in within maximum 2 months, where all are treated with SZC to test tolarability, and 2) a 1:1 randomized, double-blinded and placebo-controlled treatment during 6 months. The open-label phase, in turn, consists of three periods: run-in (1 - 2 weeks), correc-tion (maximum 72 hours) and maintenance (4-7 weeks). In addition, post-randomization phase, all patients will be followed by 3 visits (Follow-Up 1, 2 and 3) at 1, 2 and 4 weeks after End of Study (EOS) / End of Treatment (EOT) (which comes first) for further control of kalium and creatinine levels and documentation of current MRA use incl dose. Sodium Zirconium Cyclosilicate (SZC) (Lokelma)®, 5 g, 10 g, orally, is an approved drug in Sweden. For correction of hyperkalemia, the recommended starting dose is 10 g, three times daily. Once normokalemia has been achieved, the maintenance reg-imen should be started with 5 g once daily. The dose can be titrated up to 10 g once daily or lowered to 5 g once every other day as needed, to maintain a normal level of potassium. Primary Objective: To demonstrate the efficacy of Sodium Zirconium Cyclosilicate (SZC) on optimiz-ing MRA in HFrEF, SZC vs Placebo. Outcome measure: Whether a patient maintains MRA either at a dose ≥ 25 mg daily (for those without MRA at base-line) or a dose increase by 25 mg daily (for those with MRA ≤ 25 mg daily at baseline) and K level in the normal range (3.5-5.0 mmol/L) at the end of study, without rescue therapy due to hy-perkalemia at any point during the randomization phase.
This study will be an open-label, randomised sequence, 2-period, 2-cohort, 2-treatment in each cohort, cross-over study in healthy subjects (males and females of non-childbearing potential), performed at a single study centre.
