Can boosting hemoglobin help kidney transplant patients feel better and protect their kidneys?
NCT ID NCT00396435
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This study looked at whether raising hemoglobin levels with a drug called epoetin (Neorecormon) could improve quality of life and slow kidney function decline in people who had a kidney transplant and now have chronic graft dysfunction. About 128 adults who had a transplant 1 to 20 years ago and had reduced kidney function took part. They were split into two groups: one aimed for a higher hemoglobin target, the other for a lower one. The study measured quality of life after 6 months and kidney function over 24 months.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Epoetin (Neorecormon)
- What this could lead to
- If successful, this could show that managing anemia with epoetin improves daily well-being and helps preserve kidney function in transplant patients.
- What could go wrong
- This is a completed Phase 4 trial with 128 participants, so results are limited in scope. The intervention may not significantly slow kidney decline or improve quality of life for all patients.
