B-cell Lymphoma is an aggressive and rare cancer of a type of immune cell (a white blood cell responsible for fighting infections). The purpose of this study is to assess the safety and tolerability of epcoritamab in combination with anti-neoplastic agents in adult participants with Non-Hodgkin lymphoma (NHL). Adverse events and change in disease activity will be assessed.
Epcoritamab is an investigational drug being developed for the treatment of NHL. Study doctors put the participants in groups called treatment arms. The combination of epcoritamab with anti-neoplastic agents will be explored. Each treatment arm receives a different treatment combination depending on eligibility. Approximately 496 adult participants with NHL will be enrolled in 100 sites globally.
In both the dose escalation and dose expansion arms participants will receive subcutaneous (SC) epcoritamab in 28 day, 21 day, or 56 day cycles dependent on the arm in combination with the anti-neoplastic agents described below:
1: Oral lenalidomide in participants (PPTS) with relapsed/refractory (R/R) diffuse large B-cell lymphoma (DLBCL); 2: Oral ibrutinib and oral lenalidomide in PPTS with R/R DLBCL; 3: Intravenous (IV) polatuzumab vedotin, IV rituximab, IV cyclophosphamide, IV doxorubicin hydrochloride (HCl), and oral prednisone (pola-R-CHP) in PPTS with newly diagnosed treatment-naïve DLBCL, or completion of treatment in 3B; 4: Oral CC-99282 in PPTS with R/R DLBCL; 5: Oral CC-99282 in PPTS with R/R follicular lymphoma (FL); 6A: Oral ibrutinib in PPTS with R/R mantle cell lymphoma (MCL).
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.
DLBCL, not otherwise specified (NOS).
High-grade B cell lymphoma with MYC and BCL-2 and/or BCL-6 translocations per WHO 2016 ("double-hit" or "triple-hit") Note: High-grade B-cell lymphomas NOS or other double- /triple-hit lymphomas (with histologies not consistent with DLBCL) are not eligible.
Follicular lymphoma (FL) Grade 3B. OR
FL with histologically confirmed CD20+ Grade 1 to 3a and no evidence of histologic transformation to an aggressive lymphoma at most recent representative tumor biopsy, according to WHO 2016 classification. OR
Prior treatment with epcoritamab or any other bispecific antibody targeting CD3 and CD20.
Toxicities from prior anticancer therapy that have not resolved to Common Terminology Criteria for Adverse Events (CTCAE, v 5.0), Grade 2 or below, with the exception of alopecia. Other eligibility criteria (e.g., laboratory, cardiac criteria) must also be met.

Treatment groupsSee each treatment group below.
Number of Participants with Dose-Limiting Toxicities (DLT)
DLT events are defined as clinically significant adverse events or abnormal laboratory values assessed as unrelated to disease progression, underlying disease, intercurrent illness, or concomitant medications.
Best Overall Response (BOR) per Investigator
BOR is defined as the percentage of participants who achieved best overall response of CR or PR by Lugano 2014 criteria as assessed by the investigator.
Duration of response (DOR) per Investigator
DOR is defined for participants who achieved best overall response of CR or PR ('responders'), as the time in months from initial CR/PR to the earliest occurrence of radiographic progression determined by Lugano 2014 criteria as assessed by the investigator, or death from any cause.
Number of Participants with Progression-free survival (PFS)
PFS is defined as the time in months from the first dose of study drug to the earliest occurrence of disease progression determined by Lugano 2014 criteria as assessed by investigator, or death from any cause.
Percentage of Participants with Complete Response (CR)
CR is defined as the percentage of participantswho achieved best overall response of CR determined by Lugano 2014 criteria as assessed by investigator.
