Краткое содержание | The purpose of this study is to evaluate the effect of Sodium Zirconium Cyclosilicate (SZC), as adjunct to ACEi/ARB therapy (lisinopril or valsartan), on slowing CKD progression (assessed as the reduction in participant's glomerular filtration rate [eGFR] decline over time) in participants with hyperkalaemia or at high risk of hyperkalaemia. |
Подробное описание | This is a Phase 3, international, randomised withdrawal, double-blind, parallel-group, placebo-controlled study, to evaluate the effect of SZC as adjunct to RAASi therapy (lisinopril or valsartan) in slowing CKD progression in participants with CKD and hyperkalaemia or at risk of hyperkalaemia. Specifically, the study will include participants with hyperkalaemia (S-K > 5.0 to ≤ 6.5 mmol/L by central laboratory) who are on adequate or limited RAASi therapy due to hyperkalaemia, and participants with normokalaemia (S-K ≥ 3.5 to ≤ 5.0 mmol/L by central laboratory) who are on limited RAASi therapy due to high risk of hyperkalaemia. High risk of hyperkalaemia is defined as (1) participants with a previous medical history or record of hyperkalaemia within the prior 24 months who are on limited RAASi therapy despite indication in CKD; (2) participants in whom RAASi therapy is indicated in CKD but are on limited RAASi therapy and have S-K ≥ 4.7 to ≤ 5.0 mmol/L; and (3) participants in whom RAASi therapy has been discontinued or reduced to suboptimal doses because of hyperkalaemia. A participant is expected to be in the study for approximately 28 months, which includes up to 13 days for the screening period, 27 months for the intervention period, and 1 week for follow-up. The 27-month intervention period of the study consists of 3 phases, an initiation phase (up to 72 hours), a run-in phase (3 months/up to Day 90), and a maintenance phase (24 months/104 weeks). The initial dose of SZC will be administered to participants during the initiation phase. No changes will be made to the ACEi or ARB therapy at this stage. As soon as possible after the participant is confirmed to be normokalaemic at the end of the initiation phase, the participant will enter the run-in phase. Participants will receive open-label SZC and either lisinopril or valsartan. The aim of the run-in phase is to increase ACEi or ARB therapy stepwise to their maximum doses. After a 3-month run-in period for RAASi dose optimization while on SZC, participants will be randomized to SZC or placebo and followed during the subsequent 24 months of maintenance phase for efficacy and safety assessments. |

Тип вмешательства: Drug Название вмешательства: Sodium Zirconium Cyclosilicate (SZC) Описание: Powder for oral suspension in a sachet. Unit dose strength: 5 or 10 g SZC. Single dose will consist of 1-3 sachets. During Initiation Phase: S-K > 5 to ≤ 6.5 mmol/L (measured by L-Lab): Single dose contains 10 g SZC that should be suspended in 45 mL of water and administered three times daily for up to 72 hours until normokalaemic (S-K 3.5-5.0 mmol/L) S-K ≥ 3.5 to ≤ 5 mmol/L (measured by L-Lab): Single dose contains 5 g SZC that should be suspended in 45 mL of water and administered once daily for 48 hours. During Run-in and Maintenance Phases: - Single dose contains 5 g SZC administered every other day or 5, 10, or 15 g SZC administered once daily that should be suspended in 45 mL of water. Этикетка Arm Group: Sodium Zirconium Cyclosilicate (SZC) Другое имя: Lokelma TM Тип вмешательства: Drug Название вмешательства: Placebo Описание: Powder for oral suspension in a sachet. Placebo to match 5 or 10 g. Single dose will consist of 1-3 sachets. During Maintenance Phase: - Single dose contains 5 g placebo administered every other day or 5, 10, or 15 g placebo administered once daily that should be suspended in 45 mL of water. Этикетка Arm Group: Placebo Тип вмешательства: Drug Название вмешательства: Lisinopril Описание: Tablet for oral administration. Unit dose strength: 5 or 20 mg. Dosage level: 5, 10, 20, or 40 mg administered once daily. Тип вмешательства: Drug Название вмешательства: Valsartan Описание: Tablet or capsule for oral administration. Unit dose strength: 40 or 160 mg. Dosage level: 40, 80, 160, or 320 mg administered once daily. Тип вмешательства: Drug Название вмешательства: Irbesartan Описание: Tablet for oral administration. Unit dose strength: 75, 150 or 300 mg. Dosage level: 75, 150, or 300 mg administered once daily. The study is designed to use valsartan as the selected ARB therapy adjunct to SZC. However, if an actual shortage of valsartan in a local market jeopardises the ability of participants to enter or continue in the study, valsartan can be temporarily substituted with irbesartan until the shortage of valsartan is resolved. |

Критерии: Inclusion Criteria: - Capable of giving signed informed consent which includes compliance with the requirements and restrictions listed in the ICF and protocol - Must be ≥ 18 years of age at the time of signing the informed consent. For participants < 20 years of age and enrolled in Japan, a written informed consent should be obtained from the participant and his or her legally acceptable representative - Must have eGFR ≥ 25 and ≤ 59 mL/min/1.73m2 as calculated by central laboratory (CKD-EPI formula) at screening (Visit 1) - Must have UACR ≥ 200 and ≤ 5000 mg/g as calculated by central laboratory at screening (Visit 1) - Any of the following criteria, a or b, at screening (Visit 1): 1.
