Treatment Details

Study Objectives

Outcome measures can provide a clearer picture of what you can expect from a treatment.
Primary outcome measures
Time to first occurrence of SCD, stroke, or hospitalization/intervention/ED visit due to arrhythmias (atrial fibrillation [AF], bradycardia, asystole, ventricular tachyarrhythmia [VF, VT, etc.])
Secondary outcome measures
Number of hospitalizations/interventions/ED visits due to arrhythmias (AF, bradycardia, asystole, Ventricular tachyarrhythmia [VF, VT etc.])
S-K > 6.5 mmol/L (yes/no) after the LIDI at the 12 month visit
S-K of 4.0-5.5 mmol/L (yes/no) after the long interdialytic interval (LIDI) at the 12 month visit
+6 more
Other outcome measures
Adverse Events (AEs)/ Serious Adverse Events (SAEs)
Change in interdialytic weight gain (kg) as compared to baseline
Events of pre-dialysis hypokalemia (S-K < 3.0 mmol/L)
