Anti-CD19-ARTEMIS T Cells, Fludarabine Phosphate, and Cyclophosphamide in Treating Participants with CD19+ Relapsed or Refractory Non-Hodgkin's Lymphoma

Status: Active


This phase I trial studies the side effects and best dose of anti-CD19-ARTEMIS T cells when given together with fludarabine phosphate and cyclophosphamide in treating participants with non-Hodgkin's lymphoma that has come back or isn't responding to treatment. In engineered T-cell therapy, T cells (part of the immune system) are removed from the body and genetically modified in a laboratory before being transferred back into the participant. These modified cells (anti-CD19-ARTEMIS T cells) may be better able to recognize and kill cancer cells by targeting a protein on the cancer cell surface called CD19 (found on tumor cells and on normal antibody producing cells). Drugs used in chemotherapy, such as fludarabine phosphate and cyclophosphamide, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving Anti-CD19-ARTEMIS T cells together with fludarabine phosphate and cyclophosphamide may work better in treating participants with non-Hodgkin's lymphoma.

Trial Objectives and Outline


I. To estimate the maximum tolerated dose of ET190L1-ARTEMIS T cells in subjects with a relapsed and/or refractory CD19+ non-Hodgkin’s lymphoma and evaluate the overall safety of the ET190L1-ARTEMIS.


I. Evaluate the efficacy of ET190L1-ARTEMIS T cell therapy, defined as overall response rate (ORR), including complete response (CR) or partial response (PR), of subjects with relapsed/refractory CD19+ non-Hodgkin’s lymphoma who receive human ET190L1 ARTEMIS T cell therapy.

II. Evaluate the efficacy of ET190L1-ARTEMIS T cells in histologic subtypes of CD19+ non-Hodgkin’s lymphoma.

III. Evaluate duration of overall response (DOR).

IV. Evaluate progression free survival (PFS).

V. Evaluate overall survival (OS).


I. Evaluate the presence, expansion and persistence of ET190L1-ARTEMIS T cells in the peripheral blood at select time points after infusion, by quantitative polymerase chain reaction (qPCR) and/or flow cytometry.

II. Evaluate the phenotype and maturation profile of ET190L1-ARTEMIS T cells after in vitro expansion and at various time-points post-infusion by flow cytometric immunophenotyping. Markers include (but are not limited to): CD3, CD4, CD8, CD25, CD27, CD28, CD57, CD69, CD45RO, CCR7, PD1, TIM3, and Lag3.

IV. Determine the immunophenotype of malignant lymphoid cells pre- and post-treatment, at times of disease progression or therapy resistance by immunohistochemistry (IHC) (flow cytometry or sequencing, depending on tissue sampled peripheral blood versus tissue, bone marrow, lymph node) including (but not limited to): CD19, CD80, CD86, and standard immunophenotype profile dependent upon histology.

V. Investigate further correlates of ET190L1-ARTEMIS efficacy, product characteristics, and safety, with samples collected as a part of “research blood” which also includes cytokine, quantitative T cell and T cell phenotype assessment blood.

OUTLINE: This is a dose-escalation study of ET190L1-ARTEMIS T cells.

Participants receive fludarabine intravenously (IV) and cyclophosphamide IV on days -5 through -3. Participants then receive ET190L1-ARTEMIS T cells IV on day 0.

After completion of study treatment, participants are followed up on days 1-7, 11, 14, 17, 21 and 28, months 2, 3, 4, 6, 9, 12, 15, 18, 24, 36, 48, and 60. Then, they are followed up annually for up to 10 more years.
