Criteria the registry did not label

• 4.1 Inclusion Criteria
• Informed consent obtained prior to any protocol mandated assessment.
• Age ≥ 18 years.
• Patient must have relapsed or refractory EBV-positive DLBCL after a minimum of 2 prior regimens of systemic therapy.
• Patient must have exhausted all available standard of care treatment options that could potentially provide clinical benefit.
• Toxicities related to prior therapy must have returned to Grade 1 or less, or if chronic must be stable. Peripheral neuropathy must be Grade 2 or less
• Prior anti-cancer treatment must have been completed greater than 2 weeks prior to study day 1.
• Patients must have measurable disease, as defined by IWG 2007 criteria.
• ECOG performance status score of ≤2
• Adequate organ function as defined by the following criteria:
  • Absolute neutrophil count \> 1,500/microl (stable off any growth factor within 1 week of study drug administration)
  • Hemoglobin \> 9 g/dL (transfusion to achieve this level is permitted)
  • Platelet count \> 75,000/microl (transfusion to achieve this level is NOT permitted)
  • Serum aspartate transaminase (AST) and serum alanine transaminase (ALT) ≤ 2.5 x upper limit of normal (ULN);
  • Total serum bilirubin ≤ 1.5 x ULN;
  • Creatinine clearance≥ 60 ml/min as calculated per Cockcroft and Gault equation.
  • Urinary protein \< 2+ by dipstick. If dipstick ≥ 2+, then a 24-hour urine collection can be done, and the patient may enter only if urinary protein is \< 1 g/24 hour;
• Sexually active patients will agree to utilize birth control method during the study and for 18 weeks after the study is concluded, using effective birth control methods as defined in https://www.cdc.gov/reproductivehealth/unintendedpregnancy/pdf/contraceptive\_methods\_508.pdf. See Protocol Appendix C.
• Willingness and ability to comply with the study scheduled visits, treatment plans, laboratory tests and other procedures.
  • 4.2 Exclusion Criteria
• Patients with severe or active symptomatic cardiopulmonary diseases (unstable angina and/or congestive heart failure or peripheral vascular disease within the last 12 months; chronic obstructive pulmonary disease exacerbation other respiratory illness requiring hospitalization) or clinically significant psychiatric disorders; patents with effectively treated conditions (e.g. stenting for CAD) are eligible.
• Patients with metastatic disease with active central nervous system (CNS) involvement, defined as parenchymal brain or leptomeningeal involvement.
• Concurrent administration of herbal preparations.
• A serious uncontrolled medical disorder or active infection which would impair the ability of the subject to receive protocol therapy or whose control may be jeopardized by the complications of this therapy.
• Patients currently taking drugs that inhibit or induce OATP1B1 or OATP1B3 within 5 half- lives of that agent. Examples are included in Appendix B.
• Patients currently taking drugs that are proton pump inhibitors (PPIs) within 5 half- lives of that agent. Examples are included in Appendix B.
• Patients who have received a prior organ allograft or allogeneic bone marrow transplant are eligible but must have no evidence of active GVHD and be off immunosuppressive drugs.
• Current non-prescription drug or alcohol dependence;
• For all female patients, pregnancy or breastfeeding.
• All female patients with reproductive potential must have a negative pregnancy test (serum or urine) prior to enrollment.
• Other severe acute or chronic medical or psychiatric condition or laboratory abnormality that may increase the risk associated with study participation or study drug administration, or may interfere with the interpretation of study results, or in the judgment of the investigator would make the patient inappropriate for entry into the study.
• Patients with corrected QT by Fridericia's formula (QTcF) of \>470 ms are excluded.
• Patients with Post-Transplant Lymphoproliferative Disease (PTLD) are excluded.
