简要总结
Patients with refractory and/or recurrent solid tumor have poor prognosis despite complex multimodel therapy and therefore, novel approaches are urgently needed. This study attempts to treat these diseases using T cells genetically modified with a 4th generation lentiviral chimeric antigen receptor (4SCAR fused with an inducible apoptotic caspase 9 domain) targeting CD276 (B7-H3). The 4SCAR-CD276-modified T cells (4SCAR-276) can recognize and kill tumor cells through the recognition of CD276, a surface protein expressed at high levels on many types of tumors but at low levels on normal tissues. This study will evaluate the side effects and effective doses of 4SCAR-276 in treating refractory and/or recurrent tumors.

This trial record is only for global academic information registration on ClinicalTrials.gov. Neither the sponsor Beijing Meikang Jimian Biotechnology Co., Ltd. nor collaborator Shenzhen Geno-Immune Medical Institute has obtained NMPA clinical trial approval or clinical technology filing permission to carry out interventional cell therapy trials in mainland China.

Background: Patients with refractory and/or recurrent solid tumors have poor prognosis despite complex multimodal therapy; therefore, novel curative approaches are needed. The investigators are attempting to use T cells obtained directly from the patient, which can be genetically modified to express a 4th generation CD276-specific chimeric antigen receptor (4SCAR-276). The CAR molecules enable the T cells to recognize and kill tumor cells through the recognition of the surface CD276, which is expressed at high levels on tumor cells including brain tumors, Ewing's sarcoma (PNET) and many other tumors but not at significant levels on normal tissues. This study will evaluate the side effects and the best dose of a novel 4th generation anti-CD276 CAR T cells to target refractory and/or recurrent solid tumors.

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 week 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 to have hematologic toxicity.
- •For all patients enrolled in this study, themselves or their parents or legal guardians must sign an informed consent and assent.
排除标准
- •Existing severe illness (e.g. significant cardiac, pulmonary, hepatic diseases, etc.) or major organ dysfunction, or grade 3 hematologic toxicity.
- •Untreated central nervous system (CNS) metastasis: Patients with CNS tumor involvement that has been treated and/or is stable for at least 6 weeks following completion of therapy are eligible.
- •Previous treatment with other genetically engineered CD276-CAR T cells or CD276 antibody therapy.
- •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.
