Exclusion Criteria:

1. Uncontrolled infection requiring parenteral antibiotics, antivirals, or antifungals within one week prior to first dose of the first cycle of the chemotherapy regimen. Infections controlled on concurrent antimicrobial agents are acceptable, and antimicrobial prophylaxis per institutional guidelines are acceptable. Patient needs to be clinically stable as defined as being afebrile and hemodynamically stable for 24-48 hours prior to study enrollment

3. History of or active central nervous system (CNS) involvement by lymphoma
4. Prior or concomitant malignancy in the past 5 years that is currently active and likely to interfere with the patient's treatment for DLBCL or that is likely to increase the patient's morbidity or mortality
5. Concomitant illness associated with a likely survival of < 1 year
6. Any life-threatening illness, medical condition or organ system dysfunction that, in the investigator's opinion, could compromise the patient's safety, or put the study outcomes at undue risk
7. Prior chemotherapy or radiation therapy (unless related to NHL / DLBCL treatment) within the last 5 years
8. Cytotoxic drug therapy within 21 days prior to enrollment
9. Unresolved toxicity from previous anticancer therapy (unless resolved to grade ≤ 1or resolved to grade 2 only if deemed clinically not significant and approved by the Sponsor) or incomplete recovery from surgery
