Summary
This study tested a drug called siplizumab combined with donor bone marrow cells to help kidney transplant patients potentially stop taking anti-rejection drugs long-term. Only 4 people took part before the study was ended early. The goal was to find the best dose to safely allow the body to accept the new kidney without needing lifelong medication.
