  • Must have hemodialysis access consisting of an arteriovenous fistula, arteriovenous graft, or tunneled (permanent) catheter which is expected to remain in place for the entire duration of the study
  • At least 2 out of 3 pre-dialysis S K ≥ 5.5 mmol/L after the LIDI during screening
  • Negative pregnancy test for female participants of childbearing potential
  • Female participants must be 1 year postmenopausal, surgically sterile, or using one highly effective form of birth control (defined as one that can achieve a failure rate of less than 1% per year when used consistently and correctly). They should have been stable on their chosen method of birth control for a minimum of 3 months before entering the study and willing to remain on the birth control until 12 weeks after the last dose

Who cannot join

If participant requires rescue therapy (potassium binder or dialysate S-K change during screening period), the participant will be screen failed
  • Participation in another clinical study with an investigational product, device, or non-standard hemodialysis procedure administered within one month before screening
  • Involvement in the planning and/or conduct of the study (applies to both AstraZeneca staff and/or staff at the study site)

About this study

Official title: An International, Randomized, Double-Blind, Placebo-Controlled Study to Evaluate the Effect of Sodium Zirconium Cyclosilicate on Arrythmia-related Cardiovascular Outcomes in Participants on Chronic Hemodialysis With Recurrent Hyperkalemia (DIALIZE-Outcomes)

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.

Read the detailed description

This is an international, multicenter, event-driven, randomized, double-blind, parallel group, placebo-controlled study, evaluating the utility of SZC versus placebo to reduce the incidence of sudden cardiac death (SCD), stroke, and arrhythmia-related hospitalizations, interventions, and emergency department (ED) visits in participants on chronic hemodialysis with recurrent hyperkalemia.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Sodium Zirconium Cyclosilicate (SZC)Drug

    Also called Lokelma TM

    Powder for oral suspension in a sachet. A dose is titrated in 5 g increments during a period of 4 weeks from 5 g up to 15 g qd on non-dialysis days. Afterward, the dose is adjusted monthly (or more frequent based on clinical judgment) depending on the current potassium value as measured after the long interdialytic interval (LIDI).

  • SZC PlaceboDrug

    Powder for oral suspension in a sachet. A dose is titrated in 5 g increments during a period of 4 weeks from 5 g up to 15 g qd on non-dialysis days. Afterward, the dose is adjusted monthly (or more frequent based on clinical judgment) depending on the current potassium value as measured after the LIDI.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Incidence of the Composite of Cardiac Event Outcomes

    Incidence of the composite endpoint of SCD, all stroke, or hospitalization/intervention/emergency department (ED) visit due to arrhythmias is analyzed based on Cox regression model with treatment and region as covariates. Patients with no events are censored at final clinical assessment, death, or disposition event.

    Measured: From Randomization (Visit 4) up to week 129 (Randomized Study Intervention Phase)

Secondary outcomes (2)
  1. Normokalemia at 12 Months Post-randomization

    Logistic regression analysis of whether a subject is Normokalemic (S-K of 4.0 - 5.5 mmol/L ) after the LIDI at the 12-month visit.

    Measured: Randomization to 12-Month Visit

  2. Incidence of the Composite of Arrhythmia Related Events

    Incidence of the composite endpoint of hospitalization, intervention, emergency department (ED) visit due to arrhythmias is analyzed based on Cox regression model with treatment and region as covariates. Patients with no events are censored at final clinical assessment, death, or disposition event.

    Measured: From Randomization (Visit 4) up to week 129 (Randomized Study Intervention Phase)

Timeline

From the start of the study to its completion; the mark is today. Estimated dates are the sponsor’s plan.

  1. First posted19 Apr 2021
  2. Study start30 Apr 2021
  3. Primary completion7 Mar 2024
  4. Study completion7 Mar 2024

Why it stopped: The event rate observed in the study continued to be below primary assumptions, so that the completion of the study within a reasonable timeframe was deemed very unlikely.
