Could a common heart drug help kids on dialysis fight anemia?
NCT ID NCT07715318
First seen Jul 20, 2026 · Last updated Jul 21, 2026 · Updated 1 time
Summary
This phase 2 trial tests whether spironolactone, a drug usually used for heart failure and high blood pressure, can help treat anemia in children aged 6–18 who are on hemodialysis. Participants take spironolactone daily for 12 weeks alongside standard care, and researchers measure whether it reduces the dose of erythropoietin needed to manage their anemia. The study also monitors safety, especially potassium levels, in this vulnerable group.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- spironolactone
- What this could lead to
- If it works, this could offer a new way to manage anemia in children on dialysis, potentially reducing their need for erythropoietin injections.
- What could go wrong
- This is a small, early-phase trial with only 40 participants, so results may not apply broadly. Spironolactone can raise potassium levels, which is a risk in kidney patients.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: 1. Male or female patients with ages 6-18 years old undergoing regular hemodialysis (3 sessions per week for at least 6 months) 2. Pediatric patients weighing between 25 kg and 50 kg. 3. Patients with potassium level less than 5.5 mmol/L and produce urine. 4. Anemic patients "have Hb values between 9.5 and 12.5 g/dl, transferrin saturation (TSAT) less than 20%) 5. patients have been receiving stable rHuEpo therapy administered intravenously (IV) or subcutaneously (SC) for at least 8 weeks prior to randomization 6. Patients suffering from iron- restricted erythropoiesis - Exclusion Criteria: 1. Patients with acute renal insufficiency. 2. Patients with hyperkalemia (≥5.5 mmol/L) and hyponatremia (blood level less than135 mEq/L) 3. Patients with liver disease (AST \& ALT greater than 3times upper limit normal) 4. Patients with hypersensitivity to spironolactone. 5. Patients scheduled for a living donor kidney transplant within 6 weeks following consent. 6. Current or recently enrolled in another investigational drug study (within 30 days). 7. Uncontrolled pre-dialysis supine diastolic blood pressure greater than the 95th percentile for height, gender, and age on more than two occasions in the 2 weeks prior to screening. \-
