The purpose of this study is to evaluate the safety and feasibility of huCART19-IL18 cells in patients with relapsed or refractory CD19+ cancers.
This is a Phase I study to assess the safety, tolerability, manufacturing feasibility, pharmacokinetics, and preliminary efficacy of huCART19-IL18 cells in patients with CD19+ cancers. The study will take place in two parts: an initial Dose-Finding Phase and an Expansion Phase. In the dose-finding phase, the maximum tolerated dose will be determined using a Bayesian Optimal Interval (BOIN) design within each of the following disease-specific cohorts: * Cohort A: Non-Hodgkin Lymphoma (Active, Not Recruiting) * Cohort B: Chronic Lymphocytic Leukemia (Active, Not Recruiting) * Cohort C: Acute Lymphoblastic Leukemia (Active, Not Recruiting) * Cohort D (Expansion Phase): Non Hodgkin Lymphoma and Acute Lymphoblastic Leukemia (Active, Not Recruiting) will evaluate changes to cell activation method in the huCART19-IL18 manufacturing process using the recommended dose for expansion (RDE) arising out of the dose-finding phase.

Incidence of Treatment-Emergent Adverse Events as assessed by CTCAE v5.0
Cohorts A-C: Type, frequency and severity of adverse events as assessed by CTCAE V5.0. Each disease-specific cohort will be analyzed separately.
Time frame: Up to 15 years post-huCART19-IL18 infusion
Occurrence of dose-limiting toxicities (DLTs)
Cohorts A-C: Unacceptable toxicity as defined by the protocol. DLTs will be evaluated separately by each disease-specific cohort.
Time frame: 28 days post-huCART19-IL18 infusion
Determination of Maximum Tolerated Dose (MTD)
Cohorts A-C: Selected based on an isotonic regression model. The MTD will be established separately by disease-specific cohort.
Time frame: 28 days post-huCART19-IL18 infusion
Determination of a recommended dose for expansion (RDE)
Cohorts A-C: Evaluated by Cohort/dose level using a multi-criteria decision analysis.
Time frame: 3 months post-huCART19-IL18 infusion
Proportion of manufactured products that meet the product release criteria
Cohort D: Calculated based on the proportion of subjects with huCART19-IL18 products that fail to meet the product release criteria, out of the number of subjects in whom manufacturing was attempted.
Time frame: 3 months
Proportion of manufactured products that meet the assigned dose
Cohort D: Calculated based on the proportion of subjects with huCART19-IL18 products that fail to meet the assigned dose, out of the number of subjects in whom manufacturing was attempted.
Time frame: 3 months
