Safety and Cardiovascular Efficacy of Spironolactone in Dialysis-Dependent ESRD Trial (SPin-D)
End-Stage Renal Disease
About this trial
This is an interventional treatment trial for End-Stage Renal Disease focused on measuring hemodialysis, spironolactone, cardiac fibrosis, diastolic function
Eligibility Criteria
Inclusion Criteria:
- Maintenance hemodialysis therapy for end-stage renal disease
- Age 18-85 years
- ≥3 calendar months since dialysis initiation. Note if a patient has been on dialysis for ≥3 but less than 6 calendar months, there must be no hospitalizations during the 6 weeks prior to screening, and no change in estimated dry weight (EDW) within 2 weeks of the screening date.
- For women of childbearing potential, willingness to use a highly effective method of birth control for up to 4 weeks after the last dose to study drug.
- Ability to provide informed consent
Exclusion Criteria:
- Serum potassium ≥6.5 mEq/L within the 3 months prior to screening
- Serum potassium level ≥6.0 mEq/L within 2 weeks prior to the baseline visit. If a potassium value is not available through routine clinical care during this 2-week period a potassium measurement will be performed as a research test.
- Unscheduled dialysis for hyperkalemia within the 3 months prior to screening
- Pre-dialysis systolic blood pressure <100 mm Hg within 2 weeks prior to screening or at the baseline visit
- 2 or more dialysis sessions within the month prior to screening with either 2 intra-dialytic measurements of systolic blood pressure <80 mm Hg or muscle cramping, light-headedness, nausea or hypotension requiring infusion of saline or other intervention directed at hypotension
- Current dual use of angiotensin converting enzyme inhibitor (ACEI) and angiotensin receptor blocker (ARB)
- Current use of digoxin
- Current use of spironolactone or eplerenone
- Allergy to spironolactone
- Inability to maintain dialysis machine blood flow ≥300 mL/min during any of the most recent 3 dialysis sessions prior to the screening visit as an indicator of vascular access dysfunction
- Mitral valve repair or replacement
- Severe mitral valve disease by echocardiography, coronary angiography or cardiac magnetic resonance imaging
- Anticipated kidney transplant, change to peritoneal dialysis, or transfer to another dialysis unit within 9 months
- Expected survival <9 months
- Pregnancy, anticipated pregnancy, or breastfeeding
- Incarceration
- Participation in another intervention study
