Study of ET190L1 ARTEMIS™ T Cells in Relapsed and Refractory CD19+ Non-Hodgkin's Lymphoma

The trial will follow a traditional dose-escalation model to establish the MTD and recommended phase 2 dose (RP2D) of infused ET190L1 ARTEMIS™ T cells following lympho-depleting chemotherapy. Two sequential cohorts of patients will be recruited to fulfill this study, those in the dose escalation cohort (for determination of MTD and RP2D) and those in the expansion cohort (treated on the RP2D). The study will have concurrent phases of screening, pre-treatment, treatment, primary follow-up, safety, and survival follow-up. The total duration of the study involvement for the patient is 15 years. Efficacy will be assessed until progression and safety will be assessed throughout the full duration of the study. Twelve to 24 patients will be treated to determine the MTD. Following determination of the MTD, an expansion cohort consisting of 6 patients per disease subtype (n= 30) will be recruited.
