Inclusion Criteria: 1. End stage renal disease patients on hemodialysis age 22 and older, or between ages 18 and 21 with a weight ≥40 kg. 2. Clinically stable as judged by the treating physician and as demonstrated by stable medical history for 30 days prior to enrollment, physical examination, and laboratory testing. 3. Hemodialysis therapy with the ELISIO-H dialyzer for at least 3 months immediately prior to study enrollment and expected to survive for the next 12 months. 4. Expected to maintain an acceptable urea clearance (Kt/V) with a dialyzer of an approximate surface area of 1.7 m2. 5. Currently being dialyzed at an in-center setting, on a schedule of 3 times per week. 6. Able to give informed consent after an explanation of the proposed study, and willing to comply with the study requirements for therapy during the entire study treatment period. 7. Have a stable functioning vascular access (arteriovenous fistula, graft, or dual lumen tunneled catheter). Stable access should be confirmed by: 1. Kt/V ≥1.2 for past 2 measurements, and/or 2. Achievement of within 15% the prescribed blood flow rate (≥350 ml/min) over 3 treatments prior to study entry Note: must have a flow of ≥350 ml/min at the time of enrollment. 8. Participants who have given their informed consent in writing. Exclusion Criteria: 1. Are female and pregnant, lactating, or planning to become pregnant during the study period. Note: Female participants of childbearing potential, defined as a woman \<55 years old who has not had a partial or full hysterectomy or oophorectomy, must have a negative serum beta human chorionic gonadotropin (β-hCG) pregnancy test at screening. Participants of childbearing potential must use a medically acceptable means of contraception during their participation in the study. 2. Have chronic liver disease. 3. Have a known paraprotein-associated disease. 4. Have known bleeding disorders (e.g., gastrointestinal bleeding, colonic polyps, small bowel angiodysplasia, and active peptic ulcers). 5. Have had a major bleeding episode (e.g., soft tissue bleeding, blood in stool, prolonged nose bleeds, joint damage, retinal bleeding, extensive mucosal bleeding, exsanguination, cerebral hemorrhage) ≤12 weeks prior to enrolling. 6. Have had a blood (red blood cell) transfusion ≤12 weeks prior to enrollment. 7. Have had an acute infection ≤4 weeks prior to enrollment. 8. Have active cancer, except for basal cell or squamous cell skin cancer. 9. Have a known serum κ/λ FLC ratio that is less than 0.37, or greater than 3.1 10. Have a known monoclonal gammopathy (monoclonal gammopathy of uncertain significance, smoldering \[asymptomatic\] multiple myeloma, symptomatic multiple myeloma, plasmacytomas, or plasma cell leukemia). 11.

Have a positive serology test for human immunodeficiency virus or hepatitis infection. 13. Have a significant psychiatric disorder or mental disability. 14. Are scheduled for planned interventions requiring hospitalization \>1 week. 15. Are scheduled for living-donor transplantation within the study period + 3 months, plan to change to peritoneal dialysis (PD) therapy within the next 9 months, plan to change to a home hemodialysis treatment, or plan to relocate to an area where no study center is located. 16. Are currently participating in another interventional clinical study or have participated in another interventional clinical study in the past 3 months. 17. Have a history of non-compliance with HD as assessed by an investigator. 18. Have had a major cardiovascular or cerebrovascular event within 3 months of enrollment. 19. Have a history with consistent evidence of intradialytic hypotension. 20. Have uncontrolled (systolic BP \> 180 mmHg) hypertension. 21. Have had adverse reactions to dialyzer materials 22.
