Umbilical Cord Derived Mesenchymal Stem Cells for Treatment-induced Myelosuppression in Hematologic Malignancies

A Multicenter, Phase Ib/II Trial of the Safety and Efficacy of Umbilical Cord Derived Mesenchymal Stem Cells in Treatment-induced Myelosuppression in Patients With Hematologic Malignancies (USMYE Trial)

The purpose of the study is to explore the safety and efficacy of umbilical cord derived mesenchymal stem cells in treatment-induced myelosuppression in patients with hematologic malignancies.

Study Overview

• Status: Not yet recruiting
• Conditions: Infections; Hematologic Neoplasms; Anemia; Bleeding; Thrombocytopenia; Neutropenia
• Intervention / Treatment: Biological: umbilical cord derived mesenchymal stem cells

Detailed Description

Despite the improved prognosis of patients with hematologic malignancies, almost all patients will experience severe myelosuppression induced by anti-cancer treatment, leading to a series of complications such as infection due to neutropenia, bleeding due to thrombocytopenia and/or impaired major organ function such as cardiac function due to anemia, which are the main reasons for dose reduction, dose interrruptions of anti-cancer treatment, failure of hematopoietic stem cell transplantation, and also patients' treatment-related death. It is of significant clinical importance and an urgent need to promote early recovery of myelosuppression and reduce risks of related complications as well as medical burdens. Umbilical cord derived mesenchymal stem cells (UC-MSCs), as a kind of stem cells with multipotential, can widely act on the functional cell units of bone marrow microenvironment and promote the repairment and regeneration of key cells such as hematopoietic stem cells, mesenchymal stem cells and endothelial cells, thus making it an ideal means for effectively promoting recovery of myelosuppression. Patients with hematologic malignancies and treatment-induced myelosuppression will be invited to participate in the Phase Ib/II study, to receive UC-MSCs intravenous infusion and follow-up visits of up to 2 years after enrollment.
