About this study
Primary Objective: To evaluate the safety and efficacy of human umbilical cord-derived mesenchymal stem cells（hUC-MSCs） to treat refractory immune thrombocytopenia（ITP）.
Secondary Objective: To observe the changes of immune function in refractory ITP patients with human umbilical cord-derived mesenchymal stem cells（hUC-MSCs） after infusion, and to explore and reveal the mechanism of hUC-MSCs in treating ITP.
Read the detailed description
Human umbilical cord (hUC)-derived mesenchymal stem cells (MSCs) have been shown to have marked therapeutic effects in a number of inflammatory diseases and autoimmune diseases in humans based on their potential for immunosuppression and their low immunogenicity. Currently, no more data is available on the safety and effectiveness of hUC-MSCs to treat immune thrombocytopenia patients.
This is a single-arm study to evaluate the safety and efficacy of hUC-MSCs to treat refractory immune thrombocytopenia（ITP）. In addition, it is the objective of this study to observe the changes of immune function in refractory ITP patients after hUC-MSCs infusion, and to explore and reveal the mechanism of hUC-MSCs in treating ITP.
The investigator will assess the changes of the platelet counts after hUC-MSCs infusion from week 1 to week 28, and observe incidence of adverse events during and after hUC-MSCs infusion.The investigator will complete virus detection( including HBV, HCV, HIV, Syphilis, etc) at week 4 and week 16 after hUC-MSCs infusion.
The dose of hUC-MSCs will be successively divided into three increasing dose(group A: hUC-MSCs 0.5×10^6/kg, weekly for 4 weeks, 3 patients; group B: hUC-MSCs 1.0×10^6/kg, weekly for 4 weeks, 3 patients; hUC-MSCs 2.0×10^6/kg, weekly for 4 weeks, 3 patients) with 3 patients in each group according to the dose.
The principle of increasing dose will be carried out successively from low dose to high dose group. According to the results of the safety and efficacy data from these 9 patients, the investigator will determine one of the doses and expand the sample size to 6 cases.
The investigator will observe the concentration of hUC-MSCs in peripheral blood from female patients after the first hUC-MSCs infusion at 10 time points, including 30 minutes before hUC-MSCs infusion, 30 minutes, 60 minutes, 2 hours, 4 hours, 8 hours, 16 hours, 24 hours,48 hours and 96 hours after the first hUC-MSCs infusion.
The investigator will detect antibody production of hUC-MSCs in peripheral blood from the first 9 patients at 2 time points, including 30 minutes before the first hUC-MSCs infusion and 48 hours after the last hUC-MSCs infusion.
The investigator will observe the changes of immune function in refractory ITP patients after hUC-MSCs infusion at 7 time points, including one day before hUC-MSCs infusion, 2 weeks, 4 weeks, 8 weeks, 12 weeks, 16weeks and 28 weeks after hUC-MSCs infusion.

What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Changes of the platelet counts after hUC-MSCs infusion (time frame: 28 weeks). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT04014166, which also lists 9 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 21 Feb 2025.
