Philadelphia Chromosome-Negative Lymphoblastic Leukemia

This is an open-label, single-arm pilot study evaluating agenT-797, an invariant natural killer T-cell (iNKT) therapy, in combination with routine clinical care blinatumomab in subjects with Philadelphia chromosome-negative, CD19-positive B-cell acute lymphoblastic leukemia (B-ALL), who have experienced disease progression while receiving blinatumomab, become measurable residual disease (MRD)-positive following prior MRD negativity, or have relapsed disease. The primary objective of this study is to assess safety and tolerability of the first planned dose of agenT-797 in combination with blinatumomab. Secondary objectives include evaluating the efficacy of combination therapy and other predefined secondary endpoints. Up to 13 subjects will be enrolled in this study.

The goal of this research study is to evaluate a chemotherapy regiment for the treatment of newly diagnosed Philadelphia chromosome-negative acute lymphoblastic leukemia (ALL) in adolescents and young adults (AYAs). The names of the study drugs involved in this study are: * blinatumomab (a type of immunotherapy drug) * cyclophosphamide (a type of chemotherapy drug) * cytarabine (a type of antineoplastic agent) * dexamethasone (a type of synthetic glucocorticoid) * doxorubicin (a type of antineoplastic agent) * etoposide (a type of antineoplastic agent) * mercaptopurine (a type of antineoplastic agent) * methotrexate (a type of chemotherapy drug) * pegaspargase (a type of antineoplastic agent) * vincristine (a type of antineoplastic agent)
