Study of CAR T-Cells Targeting the GD2 With IL-15+iCaspase9 for Relapsed/Refractory Neuroblastoma or Relapsed/Refractory Osteosarcoma
Bu çok merkezli Faz 1 (Phase 1) çalışma, kanserle mücadelede antikorların ve T hücrelerinin özelliklerini birleştiren bir yaklaşımı incelemektedir: hastanın kendi T hücreleri, tümör hücrelerindeki GD2 hedefini tanıyacak şekilde genetik olarak değiştirilmektedir. Araştırılan ürün iC9.GD2.CAR.IL-15 T hücreleridir; çalışma müdahaleleri arasında ayrıca siklofosfamid (cyclophosphamide) ve fludarabin (fludarabine) yer almaktadır. Çalışma, nüks eden veya tedaviye dirençli (relapsed/refractory) nöroblastom (neuroblastoma) ya da osteosarkom (osteosarcoma) hastalarını kapsamaktadır; uygunluk için gereken tüm klinik ve laboratuvar verileri hasta kayıtlarından değerlendirilmektedir.

All clinical and laboratory data required for determining eligibility must be available in the subject's medical/research record which will serve as the source document. Because of the nature of iC9.GD2.CAR.IL-15 T cell product preparation, subjects will be assessed for initial study enrollment eligibility (prior to cell procurement) and then will have to meet criteria prior to starting lymphodepletion and prior to T cell infusion. Inclusion Criteria for the Study: 1. Written HIPAA authorization signed by legal guardian. 2. Adequate performance status as defined by Lansky or Karnofsky performance status of ≥ 60 (Lansky for \<16 years of age). 3. Life expectancy ≥12 weeks. 4. Histological confirmation of neuroblastoma or ganglioneuroblastoma at initial diagnosis. Bone marrow samples are acceptable as confirmation of neuroblastoma, confirmation of osteosarcoma at diagnosis 5. High-risk neuroblastoma with persistent/refractory or relapsed disease, defined as: 1. First or greater relapse of neuroblastoma following completion of aggressive multi-drug frontline therapy. 2. First episode of progressive neuroblastoma during aggressive multi-drug frontline therapy. Persistent/refractory neuroblastoma as defined by less than a complete response by the revised International Neuroblastoma Response Criteria (INRC) at the conclusion of at least 4 cycles of aggressive multidrug induction chemotherapy on or according to a high-risk neuroblastoma protocol (such as A3973 or ANBL0532). 3. Patients must be diagnosed with high risk neuroblastoma at initial diagnosis or if non-high risk at time of initial diagnosis must have had evidence of metastatic progression when \>18 months of age as defined in the protocol or relapsed or refractory osteosarcoma that is not responsive to standard treatment. 6. Measurable or evaluable disease per Revised INRC for subjects with neuroblastoma or measurable disease by Response Evaluation Criteria In Solid Tumors Criteria (RECIST) v1.1 criteria for subjects with osteosarcoma. 7. Adequate central nervous system function as defined by: 1. No known Central Nervous System ( CNS) disease 2. No seizure disorder requiring antiepileptic drug therapy Exclusion Criteria for the Study Subjects meeting any of the following exclusion criteria will not be able to participate in this study (procurement, lymphodepletion, and cell infusion). 1. Pregnant or breastfeeding (NOTE: breast milk cannot be stored for future use while the mother is being treated on study). 2. Has a known additional malignancy that is active and/or progressive requiring treatment. 3. History of hypersensitivity reactions to murine protein-containing products. 4. History of hypersensitivity to cyclophosphamide or fludarabine.
