About this study
Official title: Single-arm, Single-center Clinical Study of Mesenchymal Stem Cells in the Treatment of Refractory Primary Immune Thrombocytopenia
This study is a clinical study initiated by single-arm, single-center, multiple administration researchers. The main purpose of this study is to evaluate the safety and efficacy of mesenchymal stem cells in refractory ITP subjects. The subjects voluntarily signed the informed consent form, and after the evaluation of the screening period and the baseline period, they received 5 times of mesenchymal stem cell infusion in the treatment period, with a dose of 1 × 108/kg mesenchymal stem cells per time, with a frequency of 1 week between the first infusion and the second infusion (a time window of ±1 day), and the 3rd, 4th and 5th infusion were all 2 weeks apart from the last infusion (a time window of ±3 days). After all treatments were completed, the safety and effectiveness of D14, M1, M2, M3, M6, M9 and M12 were evaluated during the follow-up period. The subjects were followed up to M12 or those who met the withdrawal criteria withdrew early, whichever occurred first.
Read the detailed description
The overall test process is as follows: screening period (V1): sign ICF, check the screening period, judge the criteria, record the baseline demographic information and the status of the subjects. Baseline period (V2): pre-transfusion assessment was performed to record the safety and other examinations of the subjects. During the treatment period (V3): according to the method and dose specified in the scheme, MSCs was treated for 5 times. Follow up period (V5): Safety and efficacy follow-up will be conducted at D14, M1, M2, M3, M6, M9, and M12 during the follow-up period.The subjects were followed up to M12 or those who met the withdrawal criteria withdrew early, whichever occurred first.

Questions about this trial
What is this clinical trial studying?
A study testing MSC in people with ITP - Immune Thrombocytopenia, run by Guangzhou Bio-gene Technology Co., Ltd at 1 site in China.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 8 inclusion and 15 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: withdrawn, as of the sponsor's last update on 28 May 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.
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 was withdrawn before enrolling participants, so there are no results.
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?
Platelet count (time frame: From enrollment to the end of treatment at 12 moonths). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
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 28 May 2026.
