Phase I clinical trial of intra-bone marrow cotransplantation of mesenchymal stem cells in cord blood transplantation.

ABSTRACT: Mesenchymal stem cells (MSCs) have immunomodulatory properties and support hematopoiesis in the bone marrow (BM). To develop a new strategy to not only prevent graft-vs-host disease (GVHD) but also to enhance engraftment, a phase I trial of cord blood transplantation (CBT) combined with intra-BM injection of MSCs (MSC-CBT) was designed. Third-party BM-derived MSCs were injected intra-BM on the day of CBT. The conditioning regimen varied according to patient characteristics. GVHD prophylaxis was tacrolimus and methotrexate. The primary endpoint was toxicity related to intra-BM injection of MSCs. Clinical outcomes were compared with those of six controls who received CBT alone. Five adult patients received MSC-CBT, and no adverse events related to intra-BM injection of MSCs were observed. Al
