LV009

This clinical trial is designed as a single-arm, open-label, single-center investigator-initiated early-phase clinical study, whose primary objective is to evaluate the safety of LV009 Injection in the treatment of subjects with relapsed/refractory CD19-positive hematolymphoid malignancies.
Eligible subjects who have signed the informed consent form will receive an infusion of LV009 Injection. Blood samples will be collected from the subjects before and after the infusion for the evaluation of safety, pharmacokinetics, pharmacodynamics, immunogenicity and other indicators.
In addition to the baseline period, during the treatment phase, efficacy assessments will be conducted at 4 weeks, 2 months, 3 months, 6 months after the infusion of the study drug, and then at a frequency of once every 3 months from the 6th to the 24th month. Tumor assessments will be continued until the occurrence of disease progression (PD), initiation of new anti-tumor therapy, death, intolerable toxicity, decision by the investigator or voluntary withdrawal of the subject, whichever comes first.
