Efficacy and Safety of UC-MSCs for the Treatment of Steroid-resistant aGVHD Following Allo-HSCT

Phase 3
Completed
Conditions
Graft Vs Host Disease
Interventions
Drug: Anti-CD25 mAb
Registration Number
NCT04738981
Lead Sponsor
Peking University People's Hospital
Brief Summary

Randomized, open-label, multicenter study to investigate the efficacy and safety of umbilical cord-derived mesenchymal stem cells (UC-MSC) for the treatment of steroid-resistant acute graft-versus-host disease (aGVHD) following allogeneic hematopoietic stem cell transplantation (allo-HSCT), with a view to establishing an effective treatment protocol for steroid-resistant aGVHD.

Detailed Description

A total of 130 patients with steroid-resistant aGVHD after allo-HSCT are enrolled in this multicenter, randomized, controlled trial. Patients were randomized to UC-MSC + anti-CD25 monoclonal antibodies (mAb) group and anti-CD25 mAb group. The complete response (CR) rate after 4 weeks of treatment in the two groups will be compared. Adverse events are also recorded throughout the study.

Anti-CD25 mAbAnti-CD25 mAbAnti-CD25 mAb, iv, 20mg,twice in first week and once a week thereafter, for 4 weeks. Other treatment would replace it according to clinical experience if aGVHD continue to progress within 3 weeks of treatment or patients are lack of response after 4 weeks of treatment. The treatment would be repeated in another 4 weeks if patients receive partial response after first 4 weeks of treatment.

Primary Outcome Measures
NameTimeMethod
Rate of complete remission4 weeks after treatment

Complete remission of aGVHD related symptoms and indicators

Secondary Outcome Measures
NameTimeMethod
Overall survivalAt the end of Week 4 / 8 / 12 / 24 / 52.

The time from randomization to death for any reason ( the last follow-up time for missing patients; end date of follow-up for patients who are live at the end of the study).

Rate of partial remission4 weeks after treatment

improvement of aGVHD staging in one or more organs without progression in other organs

Infusion toxicityFrom the beginning of to four hours after every infusion of UC-MSC

Acute toxicity responses include impaired function of heart, kidney and liver
