a study of cta30x cell injection in patients with relapsed or refractory cd19-positive b-line hematological malignancies

Conditions: Acute Lymphoblastic Leukemia; Non-hodgkin Lymphoma

Summary: a study of cta30x cell injection in the treatment of relapsed or refractory cd19-positive b-line hematological malignancies

this is a single arm, open-label, single-center study. this study is indicated for relapsed or refractory cd19+ b-line hematological malignancy: b-all and b-nhl. the selection of dose levels and the number of subjects are based on clinical tiral of similar foreign products. 3 groups of patients will be enrolled, 36 in each group. primary objective is to explore the safety, main consideration is dose-related safety.
