CD19-Directed CAR-T Cell Therapy for the Treatment of Relapsed/Refractory B Cell Malignancies

Recruiting now · Phase 1

Conditions studied: Recurrent B-Cell Non-Hodgkin Lymphoma, Recurrent Chronic Lymphocytic Leukemia, Recurrent Small Lymphocytic Lymphoma, Recurrent Transformed Chronic Lymphocytic Leukemia, Refractory B-Cell Non-Hodgkin Lymphoma, Refractory Chronic Lymphocytic Leukemia, Refractory Small Lymphocytic Lymphoma, Refractory Transformed Chronic Lymphocytic Leukemia

In brief

This phase I trial studies the effects of CD-19 directed chimeric antigen receptor (CAR)-T cell therapy for the treatment of patients with B cell malignancies that have come back (recurrent) or have not responded to treatment (refractory). CD-19 CAR-T cells use some of a patient's own immune cells, called T cells, to kill cancer. T cells fight infections and, in some cases, can also kill cancer cells. Some T cells are removed from the blood, and then laboratory, researchers will put a new gene into the T cells. This gene allows the T cells to recognize and possibly treat cancer. The new modified T cells are called the IC19/1563 treatment. IC19/1563 may help treat patients with relapsed/refractory B cell malignancies.

Who can join

Age: 18 and older. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Age >= 18 years
• Relapsed or refractory CD19+ B cell malignancies of the one of the following histopathology:
• Biopsy proven B-cell non-Hodgkin lymphoma (NHL) of any histopathology (including Richter Transformation of CLL); relapsed or refractory disease defined as:
• Two or more prior lines of therapy, at least one anthracycline containing regimen, unless intolerable. Exception: Patients with Richter transformation of CLL are eligible if they had >= one prior treatment, including prior BTK inhibition
• Demonstration of progressive or stable disease by positron emission tomography/computed tomography (PET/CT) or CT criteria as the best response to the most recent chemotherapy regimen according to the revised Lugano Response Criteria for Malignant Lymphoma.
• Measurable disease defined as measurable by CT portion of a PET/CT: To be considered measurable, the must be at least one lesion that has a single diameter of (>1.5 cm Note: Lesions that have been previously irradiated will be considered measurable only if progression has been documented following completion of radiation therapy
• Biopsy proven SLL or flow cytometry proven CLL; relapsed disease defined as:
• >= two prior lines of therapy, and/or >= 6 months of second line prior BTK inhibition (e.g. venetoclax and ibrutinib). Exception: Patients in stable disease (SD) or partial response (PR) with a known ibrutinib resistance mutation (BTK or phospholipase Cgamma2) may be included even if on ibrutinib therapy for less than 6 months.
• Demonstration of progressive or stable disease by PET/CT or CT criteria according to the International Workshop on Chronic Lymphocytic Leukemia (iwCLL2018) criteria
• Measurable disease by CT portion of a PET/CT where at least one lesion has a single diameter of >1.5 cm or peripheral blood absolute blood lymphocyte count (ALC) of > 5000. Note: Lesions that have been previously irradiated will be considered measurable only if progression has been documented following completion of radiation therapy

• Willingness to provide mandatory blood specimens for correlative research
• Willing to return to enrolling institution for follow-up (during the Active Monitoring Phase of the study)

You may not qualify if…

• Any of the following because this study involves an investigational agent whose genotoxic, mutagenic and teratogenic effects on the developing fetus and newborn are unknown:
