GPC3-directed CAR-T in the Treatment Amongst Subjects With Advanced Hepatocellular Carcinoma

Официальное название

JWATM214，an Armored GPC3-directed CAR-T ，in the Treatment Amongst Subjects With Advanced Hepatocellular Carcinoma ：a Single-arm, Open-label，Dose-escalation Study

Обзор

This is a single arm, open-label, dose escalation clinical study to evaluate the safety and efficacy of infused autologous armored GPC3-directed CAR-T in patients with advanced hepatocellular carcinoma refractory to prior systematic treatments.

Вмешательства

• Биопрепарат CAR-GPC3 T cells
  Subjects will undergo leukapheresis to isolate peripheral blood mononuclear cells (PBMCs) for the production of JWATM214 . During JWATM214 production, subjects will receive a preconditioning chemotherapy regimen of cyclophosphamide and fludarabine to deplete the lymphocytes. After lymphodepletion, subjects will receive single-dose treatment with JWATM214 by intravenous (IV) injection.

Вторичные конечные точки (5)

• PK of JWATM214 in the peripheral blood (qPCR) [Срок оценки: 1 years]
• Objective response rate (ORR). [Срок оценки: 1 years]
• Disease Control Rate [Срок оценки: 2 years]
• progression-free survival (PFS) [Срок оценки: 2 years]
• overall survival (OS) [Срок оценки: 2 years]
