About this trial
This is a single-arm, open-label, single-center, phase I study. The primary objective is to evaluate the safety of CD7 CAR-T Bridging to allo-HSCT therapy for patients with severe aplastic anemia
Eligibility criteria
Qualifiers
Chinese expert consensus on the diagnosis and treatment of aplastic anemia(2017), Diagnosis of severe aplastic anemia ,1. The degree of bone marrow cell proliferation < 25%, or 25%-50% but residual hematopoietic cells < 30%;2. With pancytopenia (at least two of the following peripheral blood parameters) : (1) absolute neutrophil <0.5×10^9/L; (2) Platelet count< 20×10^9/L; (3) The absolute value of reticulocytes <20×109/L;
Suitable donors (relatives) with allogeneic HSCT indications and at least haploid allogeneic transplantation;
Patients who are not suitable or unwilling to undergo traditional allogeneic hematopoietic stem cell transplantation;
creatinine clearance > 60ml/min; without liver invasion, serum total bilirubin ≤ 1.5 times the upper limit of normal, and serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) were both ≤ 3 times the upper limit of the normal range. If there is liver invasion, serum erythrambirubin ≤ 3 times the upper limit of normal, and serum ALT and AST are both ≤ 5 times the upper limit of the normal range;
Disqualifiers
