Clinical Study of LV009 Injection for the Treatment of Hematologic and Lymphoid Malignancies

Clinical Study of LV009 Injection for the Treatment of Relapsed/Refractory CD19-Positive Hematologic and Lymphoid Malignancies

This clinical trial is designed as a single-arm, open-label, single-center, investigator-initiated, early-phase study. Its primary objective is to evaluate the safety of LV009 Injection in subjects with relapsed/refractory CD19-positive hematolymphoid malignancies.

3. Eastern Cooperative Oncology Group (ECOG) performance status (PS) score of 0 to 2.
4. Meets the National Comprehensive Cancer Network (NCCN) criteria for relapsed or refractory disease, with a confirmed diagnosis of CD19-positive hematolymphoid malignancy
5. Adequate hepatic, renal, and cardiopulmonary function
6. Absolute lymphocyte count (ALC) ≥ 0.5 × 10⁹/L; Platelet count ≥ 50 × 10⁹/L; CD3-positive T-cell count ≥ 150 cells/μL

Exclusion Criteria:

1. Patients who, in the investigator's judgment at screening, require long-term use of immunosuppressive agents.
2. History of cerebrovascular accident or convulsive seizures within 6 months prior to signing the informed consent form.
