Engineered immune cells take aim at stubborn childhood cancers

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Patients with tumors have received standard first-line therapy and been judged to be non-resectable，metastatic,progressive or recurrent. * The GD2 antigen status of the tumor will be determined for eligibility.Positive expression is defined by GD2 antibody staining results based on immunohistochemistry or flow cytometry analyses. * Body weight greater than or equal to 10 kg. * Age: ≥1 year and ≤ 65 years of age at the time of enrollment. * Life expectancy: at least 8 weeks. * Prior Therapy: 1) There is no limit to the number of prior treatment regimens. Any grade 3 or 4 non-hematologic toxicity of any previous therapy must have resolved to grade 2 or less. 2) Must not have received hematopoietic growth factors for at least 1 week prior to mononuclear cells collection. 3) At least 7 days must have elapsed since the completion of therapy with a biologic agent, targeted agent, tyrosine kinase inhibitor or a metronomic nonmyelosuppressive regimen. 4) At least 4 weeks must have elapsed since prior therapy that included a monoclonal antibody. 5) At least 1 weeks since any radiation therapy at the time of study entry. * Karnofsky/jansky score of 60% or greater. * Cardiac function: Left ventricular ejection fraction greater than or equal to 40/55 percent . * Pulse Ox greater than or equal to 90% on room air. * Liver function: defined as alanine transaminase (ALT) \<3x upper limit of normal (ULN), aspartate aminotransferase (AST) \<3x ULN; serum bilirubin and alkaline phosphatase \<2x ULN. * Renal function: Patients must have serum creatinine less than 3 times upper limit of normal. * Marrow function: White blood cell count ≥1000/ul, Absolute neutrophil count ≥500/ul, Absolute lymphocyte count ≥500/ul, Platelet count ≥25,000/ul (not achieved by transfusion). * Patients with known bone marrow metastatic disease will be eligible for study as long as they meet hematologic function criteria, and the marrow disease not evaluable for hematologic toxicity. * For all patients enrolled in this study, their parents or legal guardians must sign an informed consent and assent. Exclusion Criteria: * Existing severe illness (e.g. significant cardiac, pulmonary, hepatic diseases, etc.) or major organ dysfunction, with the exception of grade 3 hematologic toxicity. * Untreated central nervous system (CNS) metastasis: Patients with previous CNS tumor involvement that has been treated and is stable for at least 6 weeks following completion of therapy are eligible. * Previous treatment with other genetically engineered GD2-CAR T cells. * Active HIV, Hepatitis B virus (HBV), Hepatitis C virus (HCV) infection or uncontrolled infection. * Patients who require systemic corticosteroid or other immunosuppressive therapy. * Evidence of tumor potentially causing airway obstruction. * Inability to comply with protocol requirements. * Insufficient CAR T cells availability.
