This Phase II open label study will evaluate the safety and efficacy of repeat doses of RGI-2001 in combination with standard of care treatment for the prevention of acute graft-vs-host-disease (aGvHD) in subjects following Allogeneic Hematopoietic Stem Cell Transplantation (alloHSCT). These subjects will be compared to contemporary controls.

Official Title

An Open Label Phase 2, Study to Evaluate the Safety and Efficacy of RGI-2001 for the Prevention of Acute Graft-vs-Host Disease Compared to Contemporary Controls in Subjects Following Allogeneic Hematopoietic Stem Cell Transplantation


This is an open-label, multi-center, single-arm study to evaluate six weekly doses of RGI-2001 in combination with standard of care treatment for the prevention of aGvHD in subjects following alloHSCT. The study will include a Safety Run-in Phase to assess the safety and tolerability of 6 weekly doses of RGI-2001 followed by an Expansion Phase in which the potential efficacy of 6 weekly doses of RGI-2001 in addition to standard of care for GvHD prophylaxis will be assessed. Comparison will be made to a contemporaneous control group.
