Detailed Description
The study objective is to verify the safety and effectiveness of the DBB-EXA ES Hemodialysis Delivery System to consistently deliver dialysate of the appropriate quality for infusion. The safety will be evaluated by comparing the adverse event rate in the DBB-EXA ES Hemodialysis group (investigational) vs. the standard dialysis group (control).
The study population will include eligible adult patients diagnosed with chronic renal failure requiring routine dialysis treatments for a minimum of 90 days and with a minimum of 3 weekly sessions. Treatment duration will be at the discretion of the investigator. The duration of study participation for each subject is approximately eight (8) weeks; four (4) weeks of routine dialysis and four (4) weeks of treatment dialysis. The expected total study duration across all subjects (from recruitment to last subject visits) is approximately five (5) to six (6) months, dependent upon subject recruitment/enrollment and meeting 360 evaluable treatments. A minimum of 30 eligible subjects will be enrolled into the study ensuring a minimum of 360 evaluable treatments in the treatment arm.
The sub-study, VARRM, was conducted following the subject's completion of the primary eight (8) week clinical study. The total participation time for the VARRM sub-study was approximately 1.5 weeks. Subjects that participated in the VARRM sub-study had their vascular recirculation rates collected during treatments. A minimum of 12 subjects were expected to participate in this sub-study, with a minimum of 21 and maximum of 36 dialysis accesses evaluated.
Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: Routine first Group A subjects will be assigned to 4 weeks of routine dialysis (control group) followed by 4 weeks of treatment dialysis with the DBB-EXA ES Hemodialysis System (investigational group). |
Device: DBB-EXA ES Hemodialysis System
The DBB-EXA ES Hemodialysis Delivery System is intended to support an optional online priming, rinseback and emergency bolus features. The appropriate priming of the hollow fiber dialyzer and blood tubing lines removes debris and air prior to device use, as well as ensuring proper rinseback.

| Experimental: Investigational first Group B subjects will be assigned to 4 weeks of treatment dialysis with the DBB-EXA ES Hemodialysis System (investigational group) followed by 4 weeks of routine dialysis (control group). |

| Other: VARRM sub-study Following completion of the initial 8-week treatment, subject's were eligible to participate in the sub-study, VARRM. The total participation time for the VARRM sub-study was approximately 1.5 weeks. |

Outcome Measures
Primary Outcome Measures
- Adverse Event Rate [8 weeks]
The safety will be evaluated by comparing the adverse event rate in the DBB-EXA ES Hemodialysis group (investigational) vs. the standard dialysis group (control)
Secondary Outcome Measures
- Total Colony Forming Units and Endotoxin Levels [8 Weeks]
The effectiveness will be evaluated by comparing the total Colony Forming Units (CFUs) and endotoxin levels calculated within dialysis fluid in the DBB-EXA ES Hemodialysis group (investigational) vs. the standard dialysis group (control).
- Fluid Balance Evaluation [8 Weeks]
The impact that online priming, online rinse back and online emergency bolus, if performed, has on fluid balance will be evaluated by assessing the proportion of subjects that have a Post-Dialysis Target Weight variance of > 0.5kg in the DBB-EXA ES Hemodialysis group (investigational) vs. the standard dialysis group (control).
Other Outcome Measures
- Sub-Study VARRM [1.5 weeks]
The Vascular Access Recirculation Rate Measurement (VARRM) will be assessed by comparing the recirculation rate obtained from the DBB-EXA ES device to the non-invasive commercially approved Transonic® HD03 Hemodialysis Monitor (Transonic Systems, Inc.)
