Study of Ibrutinib in Combination With Bendamustine and Rituximab for Patients With Relapsed/Refractory Aggressive BCL
Diffuse Large B Cell Lymphoma, Primary Mediastinal (Thymic) Large B-cell Lymphoma, Transformed Indolent Lymphoma
About this trial
This is an interventional treatment trial for Diffuse Large B Cell Lymphoma
Eligibility Criteria
Inclusion Criteria:
- Adult patients over the age of 18.
- Histologically confirmed DLBCL, Transformed low grade lymphoma to DLBCL, primary mediastinal B cell lymphoma or unclassifiable lymphoma between DLBCL and Burkitt Lymphoma, either in first or second relapse/progression in patients who are not candidates for ASCT or in second relapse/progression post ASCT (as first salvage therapy following relapse/progression post ASCT).
- Pathology must be confirmed by a local hemato-pathologist. Patients with pathology sample over 1 year old will have to undergo a new diagnostic biopsy.
- At least 1 prior line of therapy with rituximab containing regimen.
- At least 1 site of measurable disease according to the Lugano criteria [1]
Hematology laboratory values must be within the following limits:
- Absolute neutrophil count (ANC)≥1000/mm3 independent of growth factor support
- Platelets ≥100,000/mm3 or ≥50,000/mm3 if bone marrow involvement independent of transfusion support in either situation.
Biochemical values within the following limits:
- Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) ≤ 3 x upper limit of normal (ULN)
- Total bilirubin ≤ 1.5 x ULN unless the increase is due to Gilbert's syndrome or of non-hepatic origin
- Serum creatinine ≤ 2 x ULN or estimated Glomerular Filtration Rate (Cockroft-Gault) ≥ 40 mL/min/1.73m2
- Women of childbearing potential and men who are sexually active must be practicing a highly effective method of birth control during and after the study consistent with local regulations regarding the use of birth control methods for subjects participating in clinical trials. Men must agree to not donate sperm during and after the study. For females, these restrictions apply for 1 month after the last dose of study drug. For males, these restrictions apply for 3 months after the last dose of study drug.
- Women of childbearing potential must have a negative serum (beta-human chorionic gonadotropin [beta-hCG]) or urine pregnancy test at screening. Women who are pregnant or breastfeeding are ineligible for this study.
- ECOG performance status 0-2.
- Sign (or their legally-acceptable representatives must sign) an informed consent document indicating that they understand the purpose of and procedures required for the study, including biomarkers, and are willing to participate in the study.
Exclusion Criteria:
Prior chemotherapy radiotherapy or major surgery within 4 weeks of cycle 1 day 1.
2. Previous treatment with either bendamustine or Ibrutinib. 3. Prior allogeneic stem cell transplantation. 4. Known central nervous system lymphoma. 5. History of stroke or intracranial hemorrhage within 6 months prior to randomization.
6. Requires anticoagulation with warfarin or equivalent vitamin K antagonists. 7. Requires treatment with strong CYP3A inhibitors. 8. Clinically significant cardiovascular disease such as uncontrolled or symptomatic arrhythmias, congestive heart failure, or myocardial infarction within 6 months of Screening, or any Class 3 (moderate) or Class 4 (severe) cardiac disease as defined by the New York Heart Association Functional Classification.
9. Vaccinated with live, attenuated vaccines within 4 weeks of randomization. 10. Known history of human immunodeficiency virus (HIV) or active Hepatitis C Virus or active Hepatitis B Virus infection or any uncontrolled active systemic infection requiring intravenous (IV) antibiotics. Hbcore positive HBs negative patients will be eligible but will need to be treated with lamivudine 100 mg/day throughout the treatment phase and 6 months after it.
11. Any life-threatening illness, medical condition, or organ system dysfunction which, in the investigator's opinion, could compromise the subject's safety, interfere with the absorption or metabolism of ibrutinib capsules, or put the study outcomes at undue risk.
12. Diagnosed or treated for malignancy other than DLBCL, except:
- Malignancy treated with curative intent and with no known active disease present for 3 years before randomization
- Adequately treated non-melanoma skin cancer or lentigo maligna without evidence of disease
- Adequately treated carcinoma in situ without evidence of disease
