Clinical Trial Summary

Acute GVHD following allogeneic HCT is an immune-triggered process, leading to profound immune dysregulation and organ dysfunction. Despite pivotal advances, aGVHD is one of the leading causes of non-relapse mortality in patients undergoing HCT. Placenta-derived DSCs, isolated from the fetal membrane of maternal origin, are a type of stromal cells with well-characterized immunosuppressive properties. The current study is designed to assess the safety and efficacy of 4 intravenous (IV) doses of ASC930 DSC cells in aGVHD patients.
