Primary Outcome Measures
NameTimeMethod
Weekly Standardized Dialysis Adequacy8 weeks per period

Weekly standardized dialysis adequacy (stdKt/V) was measured using the second-generation formula of Daugirdas. This formula normalizes urea clearance among heterogeneous hemodialysis schedules, where K=dialyzer clearance or urea, t=treatment time, and V=subject's volume of urea distribution. stdKt/V values of ≥ 2.1 are regarded as being adequate.

Incidence of Pre-Specified Adverse Events8 weeks per period

All adverse events (AEs) observed in the trial were reviewed by an independent Clinical Events Committee (CEC). AEs adjudicated into the following pre-specified categories were included in the outcome measure:

1. Serious Adverse Event

2. Allergic Reaction: to dialyzer, blood tubing or chemical disinfectant.

3. Blood Loss: that leads to death, transfusion or fluid resuscitation with greater than 1 liter of crystalloid IV fluids.

4. Hemolytic Reaction: due to disinfectant exposure, dialysate temperature, mechanical failure or other device related causes.

5. Infection: any infection related to catheter, its tunnel or exit site, AV fistula, or AV graft.

6. Intra-Dialysis Event: a significant clinical event such as loss of consciousness, cardiac arrest, or seizure caused by device failure.

7. Vascular Access Complications

8. Pyrogenic Reaction

Secondary Outcome Measures
NameTimeMethod
Ultrafiltration Rate Success8 weeks per period

The Ultrafiltration (UF) rate was calculated using the following method:

UF rate = (Fluid Removal Goal + Rinse Back Volume) / Treatment Duration.

Where: Fluid Removal Goal = (Today's Weight - Prescribed Estimated Dry Weight)

And: Rinse Back Volume = The volume of saline, 300mL, returned to the patient at the end of treatment.

Each dialysis treatment was flagged as a success with respect to UF if the actual UF rate was within 10% of the prescribed UF rate. The mean (i.e., success proportion) and standard deviation were computed by treatment period across all subjects, where the denominator for the mean calculations was the total number of treatments in each treatment period for which the subjects contributed non-missing UF data.
