Brief Title: Anti-GD2 CAR T Cells in Pediatric Patients Affected by High Risk and/or Relapsed/Refractory Neuroblastoma or Other GD2-positive Solid Tumors
Official Title: Phase I/II Study of Anti-GD2 Chimeric Antigen Receptor-Expressing T Cells in Pediatric Patients Affected by High Risk and/or Relapsed/Refractory Neuroblastoma or Other GD2-positive Solid Tumors
Study ID: NCT03373097
Brief Summary: The purpose of this study is to test the safety and efficacy of GD2-CART01, a CAR T cell treatment targeting GD2 in paediatric or young adult patients with High Risk and/or relapsed/refractory Neuroblastoma. A small exploratory cohort of patients with GD2-positive tumors other than Neuroblastoma has also been included.
Detailed Description: The study will consist of 2 phases, a Phase I or dose escalation phase and a Phase II or expansion phase. Paediatric or young adult patients with relapsed High Risk and/or relapsed/refractory Neuroblastoma will be enrolled in the study. After completion of the phase I portion of the study, a small cohort of patients with GD2-positive tumors other than Neuroblastoma has also been included. Eligible patients will undergo leukapheresis in order to harvest T cells, which will be manufactured to obtain the autologous CAR T product GD2-CART01, a GD2-targeting CAR T product. Briefly, the patients will be treated with a lymphodepleting regimen containing conventional chemotherapic agents and subsequently will receive a single infusion of GD2-CART01. Moreover, the product contains a suicide gene safety switch (namely inducible Caspase 9): in case of relevant toxicities, the patient will receive the dimerizing agent in order to activate the apoptotic pathway in the infused T cells. After infusion of CAR T cells, the patients will enter a 5-year active follow-up period.
