Official Title ICMJE | Safety and Efficacy of Universal 4SCAR7U T Cell Therapy Targeting CD7-positive Hematological Malignancies | ||||||||
Brief Summary | The purpose of this clinical trial is to assess the feasibility, safety and efficacy of universal CAR T cells based on 4SCAR7U design against CD7-positive hematological malignancies using CD7 specific universal CAR T cells. The study also aims to learn more about the function of CD7 targeting CAR T cells and their persistence in patients of hematological malignancies. | ||||||||
Detailed Description | Hematological malignancies including B-, T-cell acute lymphoblastic leukemia (B-ALL, T-ALL), B and T cell lymphoma (BCL, TCL), natural killer cell lymphoma (NKL) and acute myeloid leukemia (AML) are aggressive diseases which may express the early T cell development molecule CD7.T-ALL represents 15% of childhood and 25% of adult ALL, and T-ALL patients are prone to early disease relapse and suffer from poor treatment outcomes. According to European Group for the Immunological Characterization of Leukemias (EGIL), the presence of cytoplasmic or membrane expression of CD3 defines T-ALL. Several immunophenotypic classifications have been proposed: (TI) the immature subgroup or pro-T-ALL is defined by the expression of CD7 and cCD3; (TII) pre-T-ALL also expresses CD2 and/or CD5 and/or CD8; (TIII) or cortical T-ALL shows CD1a positivity; and (TIV), mature T-ALL is characterized by the presence of surface CD3 and CD1a negativity.Over the past few years, T cells modified with lentiviral chimeric antigen receptor (CAR) gene have been studied in different clinical settings. CD7 is a T cell surface molecule that plays important role in T cell and B cell interaction in early lymphoid development, displays membrane expression early during T cell development before TCR rearrangement, and persists through terminal stages of T cell development, and has been a well-known marker for T-ALL. CD7 is considered a promising target for the treatment of T-ALL, TCL, AML and NKL. In this study, the study proposes to investigate an universal CD7 targeting CAR-T design, 4SCAR7U in combination with alternative targeting CAR-T cells as a new strategy to treat CD7-positive hematological malignancies. The 4SCAR7U T cells are genetically engineered and manufactured in bulk amount that can be supplied off-the-shelf without being custom made from individual patients. The immediate availability of the CAR-T cells makes clinical treatment convenient and timely for rapid progressing disease or for highly immune suppressed patients. This application can be time- and cost-effective. This novel approach may also overcome problems of functionally defective autologous T cells. The purpose of this clinical trial is to assess the feasibility, safety and efficacy of the 4SCAR7U T cell product in hematological malignancies. Another goal of the study is to learn more about the function of this novel product and its persistence in the patients. |
