The following participants with relapsed DLBCL will be enrolled:
  1. Participants who received at least only one line of previous therapy and achieved either complete response (CR) or partial response (PR) for at least 24 weeks (from the last day of the last cycle) after their first line of therapy, but are not eligible for high dose chemotherapy with autologous stem cell transplantation (HD-ASCT)
  2. Participants who received more than one line of previous therapy (including HD-ASCT), and have achieved a duration of response (CR or PR) of at least 8 weeks (from the last day of the last cycle) after their last line of therapy

• Participants with a diagnosis of chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL).
• For Part 2 and Part 3 of the study, patients with primary refractory DLBCL (defined as progression of disease within 24 weeks after first line of treatment).
• For Part 2 and Part 3 of the study, participants that are eligible to undergo first-time HD-ASCT.
• For Part 2 and Part 3 of the study, participants with R/R FL, MZL/MALT, MCL, or any other NHL subtypes according to the WHO classification.
• Participants with active hepatitis A, B or C infection.
• Women who are pregnant or breastfeeding.
