A Randomized Phase II Trial Comparing a Calcineurin Inhibitor-free Graft-versus-host Disease Prophylaxis Regimen With Post-transplantation Cyclophosphamide and Abatacept to Standard of Care

Dimitrios Tzachanis, MD PhD·interventional·Posted Sep 21, 2018·Updated Oct 2, 2025

In Brief

A Phase 2 clinical trial evaluating Cyclophosphamide, abatacept, and 2 other interventions for GVHD and Hematologic Neoplasms. Completed, enrolled 43 participants across 1 site.

Detailed Summary

The purpose of this study is to investigate whether the combination of cyclophosphamide and abatacept versus the treatment used in standard of care will reduce the incidence of moderate and severe chronic graft-versus-host disease (GVHD) following hematopoietic stem cell transplantation. GVHD occurs when the cells from your donor (the graft) see your body's cells (the host) as different and attack them.
