Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to compare the efficacy of mesenchymal stem cells (MSCs) with or without granulocyte colony-stimulating factor (G-CSF) mobilized peripheral stem cells (PBSC) in treating patients experiencing poor graft function or delayed platelet engraftment after allogeneic hematopoietic stem cell transplantation.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Allogeneic hematopoietic stem cell transplantation(allo-HSCT) is the only cure for many hematologic diseases. However, about 5-27% of patients would suffer from poor graft function (PGF) and more recipients might develop delayed platelet engraftment (DPE) after allo-HSCT. These complications are associated with considerable mortality related to infections or hemorrhagic complications. Treatment of PGF and DPE usually involves hematopoietic growth factors such as granulocyte colony-stimulating factor (G-CSF) and thrombopoietin (TPO), or second transplantation, but these methods have dismal effect or even a significant risk of graft-versus-host disease (GVHD).

Mesenchymal stem cells (MSCs) are a form of multipotent adult stem cells that can be isolated from bone marrow (BM), adipose tissue, and cord blood. Clinical applications of human MSCs include improving hematopoietic engraftment, preventing and treating graft-versus-host disease after allo-HSCT and so on. Some studies have shown that MSCs combined with PBSC or cord blood could be useful to improve engraftment after HSCT. Several reports suggested MSCs might be effective in the treatment of PGF.

However, the efficacy of MSCs as single-drug treatment for PGF or DPE is unsatisfactory in our previous study. Therefore, in the present study, G-CSF mobilized PBSC will be used combined with MSCs in the patients with PGF or DPE after allo-HSCT.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

MSCs&PBSC

PBSC will be intravenously infused at a dose of 2×10\^8/kg. MSCs will be intravenously infused at a dose of 1×10\^6 cells/kg once per week or until complete response(CR) . If the patients do not achieve CR or partial remission (PR) within 4 weeks, they will swithed to other therapy. If the patients achieve PR within 4 weeks, a second course of the same treatment will be given.
