About this trial

The goal of this clinical study is to evaluate the safety and efficacy of GT801 injection in adult patients with relapsed/refractory CD19-positive B-cell hematologic malignancies and autoimmune hemolytic anemia. Interim analysis conducted when 2 patients complete primary endpoint measurement.

Disease progression or recurrence after at least second-line drug treatment;

CD19 positivity confirmed by flow cytometry and/or histopathology (excluding autoimmune hemolytic anemia);

Disqualifiers

Subjects with myelofibrosis, myelodysplastic syndromes, aplastic anemia, or other malignant hematological diseases;

Subjects with a history of or current comorbidities that cause coagulation disorders and high bleeding risk, such as disseminated intravascular coagulation (DIC), decompensated cirrhosis, esophagogastric varices, etc.;
