Brief summary

The study will evaluate the deliverability and efficacy of Ibrutinib-R-mini-CHOP chemotherapy in elderly patients with newly diagnosed diffuse large B-cell lymphoma (DLBCL). Who is it for? You may be eligible to join this study if you are aged 75 years or above and have been newly diagnosed with DLBCL for which you have received no prior treatment (excluding prednisone). Study details All participants in this study will be treated with a chemotherapy regime known as Ibrutinib-R-mini-CHOP. This will include treatment with the drugs prednisone (orally), ibrutinib (orally), rituximab intravenously ((IV) - i.e. administered directly into the vein), cyclophosphamide IV, doxorubicin IV, vincristine IV and Pegfilgrastim G-CSF (subcutaneous injection). Treatment duration will be for up to 8 x 28 day cycles as tolerated. All participants will be regularly assessed for a minimum of 2 years in order to evaluate the safety, toxicity and effectiveness of treatment.

Interventions

Pre-phase prednisone at a dose of either 40mg/m2 IV or 100mg orally (depending on drug available IV or oral) daily for 5-7 days will be mandatory. All subjects will receive ibrutinib 560mg orally daily, rituximab 375mg/m2 IV (rounded up as per local investigator discretion to the nearest 100mg) on day 1, cyclophosphamide 400mg/m2 IV day 1, doxorubicin 25mg/m2 IV day 1, vincristine 1mg IV and prednisone 40mg/m2 IV or 100mg orally daily on a 21 day schedule aiming for a total of 6 cycles.

This will be followed directly by 2 cycles of ibrutinib 560mg orally daily and rituximab 375mg/m2 IV on day 1 (rounded up as per local investigator discretion to the nearest 100mg) on a 21 day schedule. Pegfilgrastim G-CSF 6mg subcutaneous injection on day 4-5 of each cycle as tolerated.

Inclusion criteria

1. Subject must be 75 years of age or older 2. No prior treatment for DLBCL excluding prednisone 3. Histologically confirmed de novo CD20+ DLBCL 4. Stage I bulky (largest dimension of lesion >/= 6cm), II, III or IV disease by the Ann Arbor Classification 5. At least 1 measurable site of disease according to the 2014 Recommendations for Initial Evaluation, Staging and Response Assessment of Hodgkin and Non-Hodgkin Lymphoma – the Lugano Classification. The site of disease must be greater than 1.5 cm in the long axis regardless of short axis measurement. An extranodal lesion should have a longest diameter of > 1cm. 6. Eastern Cooperative Oncology Group performance status score of 0, 1, or 2 (this can be as measured after any pre-phase prednisone) 7. LVEF within institutional normal limits, as determined by Gated Heart Pool Scan, or if not available, echocardiogram 8. Minimum life expectancy of 3 months 9. Haematology values must be within the following limits: a. Absolute neutrophil count (ANC) >=1.0 x10^9/Lindependent of growth factor support b. Platelets >=100x10^9/L or >=50x10^9/L if bone marrow involvement independent of transfusion support in either situation 10. Biochemical values within the following limits: a. Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) <= 3 x upper limit of normal (ULN) b. Total bilirubin <= 1.5 x ULN unless bilirubin rise is due to Gilbert’s syndrome or of non-hepatic origin c. Creatinine Clearance (as measured by Cockroft Gault) >/= 40 mL/min/1.73m2 11. Each subject (or their legally acceptable representative) must sign an informed consent form (ICF) indicating that he or she understands the purpose of and procedures required for the study and are willing to participate in the study. 12. 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.

Exclusion criteria

1. History of treated lymphoma of any subtype 2. CNS or meningeal involvement 3. Contraindication to any drug in the chemotherapy regimen 4. Serious active co-morbid disease according to the investigator’s decision 5. Poor renal function, defined as a Creatinine Clearance Rate (as measured by Cockcroft Gault) < 40 mL/min/1.73m2 6. Poor hepatic function, defined as Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) > 3 x upper limit of normal (ULN) and/or total bilirubin > 1.5 x ULN unless bilirubin rise is due to Gilbert’s syndrome or of non-hepatic origin 7. Poor bone-marrow reserve, defined as absolute neutrophil count (ANC) < 1.0x10^9/L independent of growth factor support and/or platelet count < 100x10^9/L or < 50x10^9/L if bone marrow involvement independent of transfusion support in either situation 8.
