  2. No more than 2 prior regimens for DLBCL.
  3. Hodgkin's variant of Richter's lymphoma, accelerated CLL, composite lymphoma, interdigitating dendritic cell sarcoma, sarcoma, EBV-associated lymphoma or prolymphocytic transformation.
  4. Ongoing risk of bleeding.
  5. CNS or leptomeningeal involvement of lymphoma
  6. Concurrent clinically significant illness, medical condition, surgical history, physical finding, electrocardiogram or laboratory finding that, in the opinion of the investigator, could adversely affect the safety of the subject or impair the assessment of the study results.
