NexCAR19 (Talikabtagene Autoleucel) in Relapsed/Refractory B-Cell Malignancies (NexCAR19)

The NexCAR19 study is a national, open-label, multicenter Phase 2-3 clinical trial designed to evaluate the efficacy and safety of the anti-CD19 chimeric antigen receptor (CAR) T-cell product, Talikabtagene Autoleucel, in patients with relapsed/refractory B-cell malignancies, including B-cell Acute Lymphoblastic Leukemia (B-ALL) and Non-Hodgkin Lymphoma. The study is supported by the Presidency of Turkish Health Institutes (TÜSEB) and will be conducted at four centers. This therapy is based on collecting the patient's own T cells, genetically modifying them in a laboratory to recognize the CD19 antigen, and reinfusing them into the patient. The goal is to target leukemia or lymphoma cells and achieve disease control. The primary objective is to assess the overall response rate at Day 28 after infusion and to evaluate the safety profile of the treatment. Secondary objectives include assessment of complete response rate, duration of response, overall survival, and progression-free survival, as well as the frequency and severity of cytokine release syndrome (CRS), neurotoxicity (ICANS), and other treatment-related adverse events. In addition, the in vivo persistence and immunological effects of CAR-T cells will be evaluated. Eligible patients must be 18 years of age or older, have an adequate performance status, sufficient organ function, and meet disease-specific eligibility criteria. Key exclusion criteria include active severe infection, uncontrolled cardiac disease, active central nervous system involvement (where applicable), HIV or active hepatitis infection, pregnancy, and severe immunodeficiency. The treatment process includes leukapheresis for cell collection, administration of lymphodepleting chemotherapy if required, followed by a single infusion of CAR-T cells. Patients will be closely monitored after infusion, particularly during the early period, and both early and late adverse events, as well as treatment response, will be regularly assessed. A total of 40 patients are planned to be enrolled. The overall clinical follow-up period, including short- and long-term monitoring, is expected to last approximately 30 months. Data will be analyzed using appropriate statistical methods.
