Study in End Stage Renal Disease (ESRD) Patients on Hemodialysis Comparing the Theranova Dialyzer to Hemodiafiltration

Dialysis performed in HD mode. Treatment duration for each individual subject will vary based on clinical requirements determined by the Investigator, based on the subject's need, residual renal function, access function, tolerance to HD/HDF and other relevant factors. The participating subjects' HD/HDF prescriptions should be kept stable throughout the study.
