CD19-positive B-cell Acute

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.
