             assuming one of the prior lines includes anti-CD20 and alkylating agent (as listed in
             criterion 2) or relapsed after hematopoietic stem cell transplant

          5. Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1

          6. Adequate organ function

          7. Adequate vascular access for leukapheresis procedure
