A Study to Assess CART19 for B Cell Malignancies


About this study

The purpose of this study is to find out more about the side effects of the CAR-T therapy called IC19/1563 and what dose of IC19/1563 is safe for patients.

The therapy, IC19/1563, uses some of the patients own immune cells, called T cells, to kill cancer. T cells fight infections and, in some cases, can also kill cancer cells. In this study, some of the patient's T cells will be removed from their blood. In the laboratory, we will put a new gene into the T cells. This gene allows the T cells to recognize and possibly treat the cancer. The new modified T cells are called the IC19/1563 treatment. The dose of IC19/1563 will depend on when the patient is enrolled on to the study.


Participation eligibility

Participant eligibility includes age, gender, type and stage of disease, and previous treatments or health concerns. Guidelines differ from study to study, and identify who can or cannot participate. There is no guarantee that every individual who qualifies and wants to participate in a trial will be enrolled. Contact the study team to discuss study eligibility and potential participation.

- 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)

Exclusion Criteria:

- Sexually active males who are not willing to use contraception during the study and
