Home dialysis is in critical need of new technology to facilitate its delivery, as evidenced by the recent Advancing American Kidney Health initiative. The Tablo™ Hemodialysis System (Tablo) is the first new technology expanding to home use in nearly 15 years, designed to simplify patient self-care through automation, integrating on-demand water purification and dialysate production. This investigational device exemption (IDE) study assessed the safety and efficacy of Tablo managed in-center by healthcare professionals and in-home by patients or caregivers.


We conducted a prospective, multicenter, open label, cross-over trial comparing in-center and in-home hemodialysis using Tablo. Dialysis was prescribed four times per week during four treatment periods: 1-week Run-In, 8-week In-Center, approximately 4-week Transition and 8-week In-Home. The primary efficacy endpoint was achieving weekly standardized Kt/Vurea > 2.1. The secondary efficacy endpoint was delivered ultrafiltration within 10% of prescribed. We also collected safety and usability data.


Thirty participants enrolled, and 28 completed all trial periods. Adherence to the four treatment per week prescription was 96% in-center and 99% in-home. The average prescribed and delivered treatment session lengths were 3.4 hours for the In-Center and In-Home periods.The primary efficacy endpoint was achieved in 199/200 (99.5%) measurements during the In-Center period and 168/171 (98.3%) In-Home. The average weekly standardized Kt/Vureawas 2.8 in both periods. The ultrafiltration endpoint was achieved in 94% of patients during both the in-center and in-home periods. No pre-specified adverse events related to Tablo occurred during any trial period. The resolution time of alarms was 14 seconds in-center and 12 seconds in-home.


Tablo exceeds the target stdKt/Vurea > 2.1 for in-center and home care settings with highly accurate ultrafiltration. With patient-centric design, infrequent and easy to resolve alarms, and a demonstrated safety profile, Tablo provides a new option for expanding home dialysis in the United States, aligning with ambitious targets recently set by policymakers.
