Detailed Description

Objectives and Endpoints

Primary Objective:

To establish one of three study arms, R-CHOP/R-DHAP followed by ASCT (control arm A), R-CHOP+ibrutinib /R-DHAP followed by ASCT and ibrutinib maintenance experimental arm A+I), and R-CHOP+ibrutinib /R-DHAP followed by ibrutinib maintenance experimental arm I) as future standard based on the comparison of the investigator-assessed failure-free survival (FFS).

Secondary Objectives:

* To compare the efficacy of the three treatment arms in terms of secondary efficacy endpoints

* To determine the safety and tolerability of ibrutinib during induction immuno-chemotherapy and during maintenance and to compare the safety profile of the three treatment arms in terms of secondary toxicity endpoints

Primary Endpoint:

FFS defined as time from start of treatment to stable disease at end of immuno-chemotherapy, progressive disease, or death from any cause.

Secondary Efficacy Endpoints:

* Overall survival (OS)

* Progression-free survival (PFS) from randomization, from end of induction immuno-chemotherapy in patients with CR or PR at end of induction immuno-chemotherapy, and from the staging 6 weeks after end of induction assessment (at month 6)

* Overall response and complete remission rates at midterm, at end of induction, 3 months after end of induction immunochemotherapy (at month 6)

* PR to CR conversion rate during follow-up after end of induction immuno-chemotherapy

Secondary Toxicity Endpoints:

* Rates of AEs, SAEs, and SUSARs by CTC grade (Version 4.03) during induction immuno-chemotherapy and during periods of follow-up after response to immune-chemotherapy

* Cumulative incidence rates of SPMs

Exploratory Objectives:

* To compare feasibility of ASCT in arm A+I vs. arm A

* To compare minimal residual disease status between the three treatment groups

* To determine the impact of ibrutinib during induction immuno-chemotherapy and during maintenance therapy on the minimal residual disease status

* To determine the prognostic value of minimal residual disease status

* To determine the prognostic value of positron emission tomography with fluorine 18-fluorodeoxyglucose

* To determine clinical and biological prognostic and predictive factors

* To determine the role of total body irradiation (TBI) in ASCT conditioning

Exploratory Endpoints:

* Rate of successful stem cell mobilisations (success: separation of at least 2x2x10(6) CD34-positive cells, including a back-up)

* Rate of molecular remissions (MRD-negative patients) at midterm, at end of induction immuno-chemotherapy, and at staging time-points during follow-up in patients with remission after end of induction immuno-chemotherapy

* Time to molecular remission from start of therapy

* Time to molecular relapse for patients in clinical and molecular remission after end of induction immunochemotherapy

* RD in FDG-PET negative or positive patients after induction and ASCT

Exploratory objectives may be evaluated only in a subset of patients according to local standards and resources.
