B-cell Lymphoma is an aggressive and rare cancer of a type of immune cells (a white blood cell responsible for fighting infections). The purpose of this study is to assess the change in disease activity of epcoritamab when combined with intravenous and oral rituximab, cyclophosphamide, doxorubicin hydrochloride, vincristine, and prednisone (R-CHOP) or R-CHOP in adult participants globally with diffuse large b-cell lymphoma (DLBCL). Change in disease activity will be assessed.
Epcoritamab is an investigational drug being developed for the treatment of DLBCL. Study doctors put the participants in groups called treatment arms. Participants will receive epcoritamab combined with R-CHOP, followed by epcoritamab or R-CHOP followed by rituximab will be explored. Approximately 900 adult participants with with newly diagnosed DLBCL will be enrolled in the study in approximately 315 sites in globally.
In the Arm 1, participants will receive subcutaneous epcoritamab combined with intravenous and oral R-CHOP followed by subcutaneous epcoritamab in 21-day cycles. In the Arm 2, participants will receive intravenous and oral R-CHOP followed by intravenous rituximab in 21-day cycles.
There may be higher treatment burden for participants in this trial compared to their standard of care. Participants will attend regular visits during the study at an approved institution (hospital or clinic). The effect of the treatment will be frequently checked by medical assessments, blood tests, questionnaires and side effects.

- Number of Participants with Progression-Free Survival (PFS) with an International Prognostic Index (IPI) of 3-5 [ Time Frame: Up to Approximately 46 Months ]PFS is defined as the duration from randomization to the date of disease progression as determined by Lugano 2014 criteria as assessed by Independent Review Committee (IRC), or death due to any cause whichever comes first.
- Number of Participants with PFS [ Time Frame: Up to Approximately 46 Months ]PFS is defined as the duration from randomization to the date of disease progression as determined by Lugano 2014 criteria as assessed by IRC, or death due to any cause, whichever occurs first.
- Number of Participants with Event-free survival (EFS) [ Time Frame: Up to Approximately 46 Months ]EFS is defined as the duration from randomization to the date of disease progression determined by Lugano criteria as assessed by IRC, IRC-assessed PR or SD followed by non protocol-specified NALT, a positive biopsy on or after end-of-treatment (EOT), regardless of whether NAL initiated, or death from any cause.
- Percentage of Participants with Complete Remission (CR) [ Time Frame: On or After to Approximately 28 Weeks ]CR is defined as the absence of lymphoma determined by fluorodeoxyglucose positron emission tomography (FDG-PET),determined by Lugano 2014 criteria as assessed by IRC.
- Overall survival (OS) [ Time Frame: Up to Approximately 76 Months ]OS is defined as time from randomization until death due to any causes.
- Percentage of Participants with Minimal Residual Disease (MRD) Negativity [ Time Frame: Up to Approximately 46 Months ]The MRD negativity rate is defined as the percentage of participants who achieve MRD negativity prior to the initiation of any non-protocol-specified new anti-lymphoma therapy.
