Brief Summary

Study Description: This retrospective protocol focuses on characterizing clinical outcomes and toxicities following CAR T-cell therapy. Objectives: Primary To evaluate the Response Free Survival (RFS) at 6 months following CD19 CAR stratified by prior blinatumomab vs no prior blinatumomab To retrospectively evaluate outcomes following CAR T-cell therapy across children and young adults with B-ALL Secondary To evaluate the RFS at 12 months following CD19 CAR stratified by prior blinatumomab vs no prior blinatumomab and other immunotherapy. To evaluate the incidence of CD19 negative versus CD19 positive relapse following CD19 CAR stratified by prior blinatumomab vs no prior blinatumomab. To evaluate the Complete Response (CR) rate following CD19 CAR stratified by prior blinatumomab vs no prior blinatumomab. To evaluate the Minimal Residual Disease (MRD) negative remission rate following CD19 CAR stratified by prior blinatumomab vs no prior blinatumomab. Study Population and Source of Data: Subjects who were less than \< 25 years of age at the time of diagnosis and received a CAR T-cell product for B-ALL.

Study Population

Subjects who were \< = 25 years of age at the time of diagnosis and received a CAR T-cell product for B-ALL. This protocol will be amended to incorporate new research objectives and new data as necessary

* Subjects will not be recruited for this study; however, up to 210 subjects records will be selected from treatment protocols who received CAR therapy for B-ALL. Subject who opted out of the future use of his/her data will be excluded. The subjects enrolled to a CAR T cell therapy treatment protocol within the Pediatric Oncology Branch unless, are \< 25 years of age at the time of diagnosis and must have received prior a CAR T-cell product.
