* Adequate vascular access for leukapheresis procedure
* Subjects who have received previous CD19-targeted therapy must have CD19-positive lymphoma confirmed on a biopsy since completing the prior CD19-targeted therapy
* Subjects must agree to use appropriate contraception.

Exclusion Criteria:

* Subjects with central nervous system (CNS)-only involvement by malignancy (note: subjects with secondary CNS involvement are allowed on study)
* History of prior allogeneic hematopoietic stem cell transplant
* Treatment with alemtuzumab within 6 months of leukapheresis, or treatment with fludarabine or cladribine within 3 months of leukapheresis
