Use of G-CSF and blood transfusion is allowed., Life expectancy of at least one month, in the opinion of the investigator., Investigator believes that the subject (or the subject’s legally acceptable representative[s]) understands the nature, scope and possible consequences of the study.
排除标准
- •Has received any systemic treatment for aGvHD other than corticosteroids +/- CNI (prophylaxis or treatment). Treatment with CS is allowed for up to 72 hours prior to Day 0., Known sensitivity to dimethylsulfoxide (DMSO) or any other component of CYP-001., Known or suspected current alcohol or substance abuse problem, in the opinion of the investigator., Received any investigational treatment agent within 30 days or within 5 half-lives of Screening, whichever is greater., Female subject of childbearing potential either not using or not willing to use an acceptable method of contraception to avoid pregnancy during the study and for 6 months after receipt of the last dose of investigational product. All female subjects are assumed to be of childbearing potential except: •Subjects aged > 60 years and postmenopausal. •Subjects aged 45 to 60 years (inclusive) with amenorrhea for = 1 year with documented evidence of follicle-stimulating hormone level > 30 IU/L. If the follicle-stimulating hormone value is not available before randomization, a urine pregnancy test is required. •Subjects who are surgically sterile for at least 3 months before providing informed consent., Pregnant, breastfeeding or not willing to cease breastfeeding., Currently receiving a therapy not permitted during the study., Involved in the planning and / or conduct of the study (applies to Cynata Therapeutics Limited staff, staff at the study site, and third-party vendors)., Clinical presentation of chronic GvHD or overlap syndrome with both acute and chronic features of GvHD, Presence of relapsed primary malignancy since allogeneic HSCT, Have received more than one allogeneic HSCT, Clinically significant respiratory, renal or cardiac disease at screening including any of the following: a.requiring mechanical ventilation or having resting SO2 <90% on pulse oximetry b.serum creatinine >2mg/dL or eGFR <30ml/min (Cockroft Gault equation) c.uncontrolled hypertension d.Congestive heart failure New York Heart Association Class III or IV, Presence of cholestatic disorders or sinusoidal obstructive syndrome/veno-occlusive disease of the liver defined as persistent bilirubin abnormalities not attributable to aGvHD, Presence of any active uncontrolled infection requiring treatment and which in the opinion of the Investigator and/or Study medical monitor is likely to impact on the ability of the subject to participate in the trial.

If the treatment for CMV, EBV, HBV, HCV has commenced the subject is eligible for study., Any other medical or psychiatric condition which, in the opinion of the Investigator and/or Study medical monitor, makes the subject unsuitable for participation in the study or interfere with interpretation of study data.
