Brief Summary:
This is a phase I/II trial of T-cell expressing an anti-CD22 Chimeric-Antigen-Receptor (CAR) in patients with CD22 expressing B-cell malignancies. This trial is an open label, single-arm, for pediatric and adult patients with relapsed/refractory B-cell malignancies.
Detailed Description:
B-cell precursor Acute Lymphoblastic Leukemia (ALL) is the most common pediatric cancer, and an adult malignancy with poor prognosis. B-cell non-Hodgkin lymphoma (NHL) and common lymphocytic leukemia (CLL) arise from mature B-cells, and are more commonly seen in the adult and elderly population. In the recent decade, advances in immunotherapy targeting cell surface markers, using antibodies, antibody-drug conjugates, bispecific antibodies or CAR-T cells, have improved the outcome of patients with relapsed and refractory B-cell malignancies. CAR-T cell products targeting CD19, a common B-cell antigen, are approved for B-cell malignancies. Treatment with CD19 CAR-T cells was FDA approved for pediatric ALL, adult ALL, diffuse large B-cell lymphoma (DLBCL), follicular lymphoma, mantle-cell lymphoma (MCL) and primary mediastinal B-cell lymphoma (PMBCL). Still, most patients with B-cell malignancies treated nowadays with commercial CD19 CAR T-cells relapse. To address this, alternative immunotherapy targets have been proposed. CD22 is an additional co-receptor on B-cells, commonly expressed in B-cell malignancies such as ALL, and has been most studied in this context. Autologous T cells will be harvested from patients with B-cell malignancies and then activated and transduced with a retrovirus containing a chimeric-antigen receptor (CAR), manufactured by the Advanced Biotherapy Center (ABC) at the Sheba Medical Center. Patients will undergo a one-time cell collection via apheresis, after which the cells will be sent to the laboratory for activation and introduction of a gene that recognizes the CD22 antigen. Patients will receive lymphodepleting chemotherapy followed by a single dose of CD22 CAR-T cells, after which they will be monitored and undergo various research assessments (including blood tests, genetic tests, and assessments of the disease status). Patients will be closely monitored for approximately 3 months after treatment to assess response and safety of the treatment. Long-term survival monitoring will take place once a year for 15 years.
