Brief summary
To find the highest tolerable dose of dualCAR-NK19/70 (a type of cell therapy) that can be given to patients who have B-cell lymphoma that is relapsed or refractory.
Detailed description
Primary Objectives: --The primary objective is to determine the safety and identify the maximum tolerated dose (MTD) or recommended phase 2 dose (RP2D) of dualCAR-NK19/70 in patients with r/r B-cell lymphomas. Hypothesis: DualCAR-NK19/70 will be safe, well-tolerated, and effective in patients with r/r B-cell lymphomas. Secondary Objectives: --The secondary objective is to determine the efficacy in adults with r/r LBCL and FL grade 3B treated at the MTD or RP2D of dualCAR-NK19/70. Although the clinical benefit of dualCAR-NK19/70 has not yet been established, the intent of offering this treatment is to provide a possible therapeutic benefit, and thus the patient will be carefully monitored for tumor response and symptom relief in addition to safety and tolerability. Secondary endpoints include overall response rate (ORR; including CR + PR) and CR rate as defined by the Lugano Classification response criteria for malignant lymphoma, DOR, PFS, and OS. Exploratory Objectives: --The exploratory objectives are to assess the cellular kinetics and pharmacodynamic effects of dualCAR-NK19/70 and to evaluate biomarkers associated with response, resistance, and toxicity after administration of dualCAR-NK19/70 in blood and tumor samples.
