About this study

This trial is testing different drug combinations after a stem cell transplant to prevent graft-versus-host disease (GVHD). It involves comparing new drug combinations to standard treatments, and also assessing the safety of each combination. Participants will receive regular check-ups, take surveys about their well-being, and provide blood and stool samples.

Based on ClinicalTrials.gov records.
