About this study

This is a Phase I clinical trial being conducted in humans for the first time, aiming to evaluate a novel cell therapy called NEUK203-13 Injection for the treatment of patients with advanced small cell lung cancer (SCLC) who have failed systematic therapy or late stage neuroendocrine tumors(NETs). The primary goal of the study is to determine the safety and tolerability of this new therapy and to preliminarily observe its anti-tumor effects. NEUK203-13 Injection is an "off-the-shelf" CAR-NK cell therapy developed based on induced pluripotent stem cell (iPSC) technology, targeting the DLL3 protein highly expressed in SCLC or other neuroendocrine tumors(NETs) . Primary Objective Primary Endpoint aims to evaluate safety and tolerability Secondary Endpoints aim to preliminarily observe efficacy and investigate the pharmacokinetics of the drug in the body. Two pre-set dose levels are planned, with an enrollment of 7-9 patients. Treatment Regimen 1. Lymphodepletion Conditioning: Chemotherapy (Cyclophosphamide + Fludarabine) before cell infusion to clear lymphocytes in the body. 2. Cell Infusion: NEUK203-13 is administered via intravenous infusion, d1,d4 and d7 for three doses. 3. Supportive Medication: Concurrent use of IL-2 (Interleukin-2) d1, d4, d7 and d10 to support NK cell persistence. Target Patient Population Patients with advanced SCLC who have progressed after prior platinum-based chemotherapy or late stage neuroendocrine tumors(NETs) and have a relatively good perfor…
