Treatment of hematologic malignancies with patient-derived anti-CD19 chimeric antigen receptor (CAR) T-cells has demonstrated long-term remissions for patients with otherwise treatment-refractory advanced leukemia and lymphoma. Conversely, CAR T-cell treatment of solid tumors, including advanced gastric cancer (GC), has proven more challenging due to on-target off-tumor toxicities, poor tumor T-cell infiltration, inefficient CAR T-cell expansion, immunosuppressive tumor microenvironments, and demanding preconditioning regimens. We report the exceptional results of autologous Claudin18.2-targeted CAR T cells (CT041) in a patient with metastatic GC, who had progressed on four lines of combined systemic chemotherapy and immunotherapy. After two CT041 infusions, the patient had target lesion complete response and sustained an 8-month overall partial response with only minimal ascites. Moreover, tumor-informed circulating tumor DNA (ctDNA) reductions coincided with rapid CAR T-cell expansion and radiologic response. No severe toxicities occurred, and the patient's quality of life significantly improved. This experience supports targeting Claudin18.2-positive GC with CAR T-cell therapy and helps to validate ctDNA as a biomarker in CAR T-cell therapy. Clinical Insight:Claudin18.2-targeted CAR T cells can safely provide complete objective and ctDNA response in salvage metastatic GC.
In the first place you have to be lucky to be in USA to qualify for testing for car T cell clinical trial. Spore people have to be able to afford to pay for it. Got such good deal free clinical trial for super expensive car T cell?

And she also said she then did chemo plus immunotherapy after that. So lucky to qualify for two clinical trials and immunotherapy. Looks like all costs covered, never see USA or Europe cancer YouTubers worry or complain costs of immunotherapy. Aren’t they expensive cancer drugs?
