About

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.

Full 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.
