Summary
This study tests whether giving patients a transplant of healthy gut bacteria (from donated stool) can prevent severe graft-versus-host disease (GVHD) after a stem cell transplant. GVHD is a serious complication where donor immune cells attack the patient's body. The trial involves 138 adults receiving a stem cell transplant, and half will get the fecal transplant while the other half gets a placebo. The goal is to see if restoring healthy gut bacteria reduces the risk of severe GVHD.
