About this trial
This is a randomized, single-center phase 1/2a clinical trial without blinding. Regulatory T cells (Tregs) have shown potential in treating various immune-related diseases, including autoimmune disorders, transplant rejection, and inflammatory diseases. The investigators plan to recruit participants for a clinical trial to evaluate the efficacy and safety of autologous Tregs in the treatment of GVHD.
Eligibility criteria
Qualifiers
Patients aged ≥18 years who have undergone allogeneic hematopoietic stem cell transplantation (allo-HSCT), regardless of gender.
Those with persistent manifestations of graft-versus-host disease (GVHD) and suitable for systemic treatment.
Previously received at least 1 but not more than 5 lines of systemic treatment for GVHD.
Corticosteroid therapy dose stable for the two weeks before screening; or, if taking prednisone or an equivalent dose of other corticosteroids at a dose >0.5mg/kg/day for four weeks, with ongoing GVHD manifestations and no improvement; or, if two attempts to taper steroids to a lower dose have failed, and it is necessary to increase the prednisone dose to >0.25mg/kg/day or an equivalent dose.
Disqualifiers
Patients who have received experimental treatment for systemic GVHD within the 28 days prior to enrollment, which was effective and could completely alleviate immunosuppression.
Blood cancer relapse (according to the corresponding criteria for relapse of the primary blood cancer) or post-transplant lymphoproliferative disease at the time of screening.
Absolute neutrophil count (ANC) <1.5×10^9/L (excluding GVHD as the cause).
Platelet count <50×10^9/L (excluding GVHD as the cause).
