Eligibility criteria
Inclusion Criteria:
* Male or female subject at least 18 years of age.
* Has received allogeneic hematopoietic stem cell transplantation (allo-HSCT).
* Clinical diagnosis of Grade II-IV aGVHD per MAGIC guideline requiring systemic immune suppressive therapy.
* Initiation of systemic steroids therapy ≤ 72 hours.
* Negative result of serum HCG within 72 hours before enrollment for female with potential fertility.
* Have a life expectancy of 10 weeks or more.
* Able to understand and comply with the planned procedure as required by the protocol, and sign a written informed consent form (ICF).
Exclusion Criteria:
* Has received more than 1 allo-HSCT.
* Presence of morphologic relapsed primary malignancy, treatment for relapse after alloHSCT was performed, or requirement for rapid immunosuppressive treatment withdrawal for early malignancy relapse.
* Evidence of graft failure based on cytopenia(s), and as determined by the investigator.
* Evidence of post-transplant lymphoproliferative disease.
* Any prior therapy for acute GVHD, except for alloHSCT prophylaxis regimens or systemically administered corticosteroids.
* aGVHD induced by donor lymphocyte infusion(DLI).
* Clinically or suspected diagnosed of cGVHD or overlap syndrome.
* Unresolved toxicity or complications due to allo-HSCT,other than aGVHD.
* Any clinical or laboratory abnormalities that is likely to negatively affect the reliability of the study safety data, as determined by the investigator.
* Presence of any uncontrolled active infections, which was defined as hemodynamic instability due to sepsis or worsening of new symptoms, signs, or imaging findings due to infection.
* Presence of any uncontrolled and active infections.
* Presence of active and uncontrolled viral infections at screening.
* History of active tuberculosis within 6 months prior to screening or negative result of interferon-gamma release assay at screening.
* History of class III or IV congestive heart failure per New York Heart Association, clinically significant or uncontrolled unstable angina or myocardial infarction, cerebrovascular accident, or pulmonary embolism within 6 months prior to screening.
* Severe impaired renal function at screening (serum creatinine \> 1.5 ULN or creatinine clearance \< 30mL/min).
* Presence of persistent bilirubin abnormalities induced by hepatic sinusoidal obstruction, hepatic veno-occlusive disease, non-GVHD or progressive organ dysfunction at screening.
* Serum ALT and AST \> 4 ULN at screening.
* Absolute lymphocyte count \< 0.5×109/L at screening.
* Any major surgical procedures performed within 4 weeks prior to screening, that is likely to negatively affect the evaluation of the study safety data, as determined by the investigator.
* Any malignant tumor other than the transplanted tumor within 5 years before screening.
* Suspected allergic to the experimental drug product or any of its excipients.
* Currently pregnant, breastfeeding,or planning to become pregnant or not using reliable method to avoid pregnancy during study and within 3 months after the last study treatment.
* As determined by the investigator, any medical, psychiatric, or other condition or circumstance that is likely to negatively affect the reliability of the study data.
