NCT06242041

Brief Summary

This study is a multicenter, prospective and randomized controlled study. The experiment includes a 1-week screening period (1 week before dialysis) and a 7-week treatment period (1-4 weeks of dose drip period and 5-7 weeks of evaluation period). During the screening period, all patients were randomly divided into the control group and the treatment group. On the non-dialysis day of the treatment period, the treatment group was given a certain dose of sodium zirconium silicate, and the blood potassium value was measured before and after each dialysis to maintain the blood potassium at 4.0-5.0mmol/L before dialysis. At the same time, 12-lead ECG and 24-hour Holter were completed at the first and last dialysis during the treatment period, and finally the ECG stability and its relationship with blood potassium were evaluated.

Outcome Measures

Primary Outcomes (2)

  • Potassium lowering effect

    The decrease of serum potassium in the treatment group before dialysis after using sodium zirconium silicate was compared with that in the control group.

    7 weeks.

  • Changes of ECG stability during dialysis.

    To compare the changes of ECG activity between the treatment group and the control group during dialysis after potassium reduction treatment.

    7 weeks.

Study Arms (2)

Treatment group

EXPERIMENTAL

Routine treatment, and on the non-dialysis day, sodium zirconate silicate is given four times a week, starting from 5g/ day each time, and the blood potassium before dialysis is maintained at 4.0-5.0mmol/L, which can be adjusted by 10g/ week each time, and the highest dose can be increased to 80g/ week.

Drug: sodium zirconium cyclic silicate

Control group

PLACEBO COMPARATOR

Routine treatment.

Drug: sodium zirconium cyclic silicate

Interventions

On the non-dialysis day, the drug was given to patients in the treatment group, four times a week, starting from 5g/day each time, and the blood potassium before dialysis was maintained at 4.0-5.0mmol/L, which could be adjusted at 10g/week each time, and the highest dose could be increased to 80g/ week.

  • Severe hematological abnormalities: white blood cells\>20×10\^9/L, platelets≥450×10\^9/L.
  • Rhabdomyolysis was diagnosed 4 weeks before screening.
  • Taking lactulose, rifaximin or other unabsorbed antibiotics to treat hyperammonemia within 7 days before taking the first medicine.
  • Patients cannot take sodium zirconium silicate orally.
  • The patient is allergic to sodium zirconium silicate or other components of the drug.
  • The life expectancy of patients is less than 1 year.
  • Patients during pregnancy and lactation.
  • Female patients preparing for pregnancy during the study period.
  • Participated in clinical research of other drugs in the month before screening.
  • Persons who have lost their autonomous capacity.
