Title: Frequent Hemodialysis Network: Nocturnal Trial
Brief Summary: The Frequent Hemodialysis (FHN) Nocturnal Trial is a randomized controlled trial recruiting subjects from dialysis units associated with designated Clinical Centers in the U.S. and Canada and followed for 12 months. Subjects will be randomized to conventional hemodialysis delivered three days per week home arm or to the six times per week nocturnal home hemodialysis arm which will follow any dialysis prescription provided their prescribed standardized Kt/V is at least 4.0 and treatment time is at least 6.0 hours, six times per week.


Options:
A: Inclusion Criteria:

1. Patients with end stage renal disease requiring chronic renal replacement therapy
2. Age ≥ 18 years,
3. Achieved mean eKt/V of ≥ 1.1 during Baseline

Exclusion Criteria:

1. GFR greater than 10 ml/min/1.73 m2 as measured by the average of urea and creatinine clearances obtained from a urine collection of at least 24 hours
2. Expectation that native kidneys will recover kidney function
3. Current access is temporary non-tunneled catheter
4. Unable to follow the nocturnal home hemodialysis training protocol for any reason, including inability to train the patient or the patient's caregiver
5. Non-compliance with hemodialysis or peritoneal dialysis treatments in the past
6. Medical conditions that would prevent the patient from performing the cardiac MRI procedure (e.g., inability to remain still for the procedure, a metallic object in the body, including cardiac pacemaker, inner ear (cochlear) implant, brain aneurysm clips, mechanical heart valves, recently placed artificial joints, and older vascular stents)
7. Unable to verbally communicate in English or Spanish
8. Current requirement for hemodialysis more than three times per week due to medical comorbidity (ultrafiltration session on fourth day per week not an exclusion criteria)
9. Currently on daily or nocturnal HD, or less than 3 months since the patient discontinued daily or nocturnal HD
10. Scheduled for living donor kidney transplant, change to peritoneal dialysis, or plans to relocate to an area outside of the referral area of one of the Clinical Centers within the next 12 months
11. Expected geographic unavailability at the Clinical Center (for standard arm patients) or at home (for nocturnal arm patients) for \> 2 consecutive weeks or \> 5 weeks total during the next 12 months (excluding unavailability due to hospitalizations)
12. Less than 3 months since the patient returned after acute rejection resulting in allograft failure
13. Currently in acute care or chronic care hospital
14. Life expectancy less than six months
15. A medical history that might limit the individual's ability to take trial treatments for the 12 month duration of the study, including: currently receiving chemo or radiotherapy for a malignant neoplastic disease other than localized non-melanoma skin cancer, active systemic infection (including tuberculosis, disseminated fungal infection, active AIDS but not HIV), and cirrhosis with encephalopathy
16. Current pregnancy or planning to become pregnant within the next fourteen months (patients require a higher dose of dialysis if pregnant). All female patients that have not gone through menopause will need to use an effective contraceptive method while enrolled in the study.
17. Contraindication to heparin, including allergy or heparin induced thrombocytopenia
18. Current use of investigational drugs or participation in an interventional clinical trial that contradicts or interferes with the therapies or measured outcomes in this trial
19. Unable or unwilling to follow the study protocol for any reason (including mental incompetence)
20. Unable or unwilling to provide informed consent or sign IRB-approved consent form
B: Inclusion Criteria:

1. Patients with end stage renal disease requiring chronic renal replacement therapy
2. Age 13 years or greater
3. Achieved mean eKt/V of \> 1.0 on at least two baseline sessions
4. Weight 30 kg or greater

Exclusion Criteria:

1. Residual renal urea clearance \> 3 mL/min per 35 L.
2. Expectation that native kidneys will recover
3. Vascular access being used for HD is a non-tunneled catheter
4. Inability to come for in-center 6 days a week, including inability to arrange adequate transportation
5. History of poor adherence to thrice weekly HD
6. Medical conditions that would prevent the subject from performing the cardiac MRI procedure (e.g., inability to remain still for the procedure, a metallic object in the body, including cardiac pacemaker, inner ear (cochlear) implant, brain aneurysm clips, mechanical heart valves, recently placed artificial joints, and older vascular stents)
7. Unable to verbally communicate in English or Spanish
8. Requires HD \> 3 times per week due to medical co-morbidity (such as, but not limited to: systemic oxalosis, or requiring total parenteral nutrition). Occasional ultrafiltration on a fourth day per week is not an exclusion criterion.
9. Currently on daily or nocturnal HD, or less than 3 months since the subject discontinued daily or nocturnal HD
10. Scheduled for living donor kidney transplant, change to peritoneal dialysis, home HD, or plans to relocate to another center within the next 14 months
11. Expected geographic unavailability at a participating HD unit for \> 2 consecutive weeks or \> 4 weeks total during the next 14 months (excluding unavailability due to hospitalizations) (frequent HD subjects who leave for vacation may resort back to conventional HD during these time periods)
12. Less than 3 months since the patient returned to HD after acute rejection resulting in allograft failure
13. Currently in acute or chronic care hospital
14. Life expectancy \< 6 months
15. A medical history that might limit the subject's ability to take trial treatments for the 12 month duration of the study, including: currently receiving chemo or radiotherapy for a malignant neoplastic disease other than localized non-melanoma skin cancer, active systemic infection (including tuberculosis, disseminated fungal infection, active AIDS but not HIV, and cirrhosis with encephalopathy)
16. Current pregnancy, or actively planning to become pregnant in the next 12 months
17. Contraindication to heparin, including allergy or heparin induced thrombocytopenia
18. Current use of investigational drugs or participation in another clinical trial that contradicts or interferes with the therapies or measured outcomes in this trial
19. Unable or unwilling to follow the study protocol for any reason (including mental incompetence)
20. Unable or unwilling to provide informed consent or sign IRB-approved consent form
