Objectives

Narrative objectives1

This study aims to evaluate the effectiveness of epcoritamab in patients with 3L+ R/R LBCL (including diffuse large B-cell lymphoma [DLBCL], high-grade B-cell lymphoma [HGBCL], primary mediastinal large B-cell lymphoma [PMBCL], and follicular lymphoma [FL] grade 3B) who are treated with epcoritamab in real-world settings in Japan. Additionally, this study also aims to assess patient characteristics, safety information, details on treatment patterns, and healthcare resource utilization (HCRU), in order to investigate treatment outcomes of epcoritamab in real-world settings.

Assessment

Primary outcomes

To characterize real-world outcomes among patients with 3L+ R/R LBCL treated with epcoritamab, balanced and similar to the EPCORE NHL-1 aNHL trial cohort (ClinicalTrials.gov: NCT03625037) on key patient characteristics (Target Trial Emulation Cohort).
[Primary Endpoints]
Complete response rate (CRR), best objective response (BOR), overall survival (OS)

Key secondary outcomes

1. To characterize real-world outcomes in Target Trial Emulation Cohort.
[Secondary Endpoint 1]
Real-world duration of response (rwDOR), real-world duration of complete response (rwDOCR), real-world progression-free survival (rwPFS), duration of treatment (DOT), time to next treatment (TTNT)

2. To characterize real-world outcomes in patients with 3L+ R/R LBCL treated with epcoritamab (All Epcoritamab Cohort).
[Secondary Endpoint 2]
CRR, BOR, OS, rwDOR, rwDOCR, rwPFS, DOT, TTNT

3. To characterize adverse events (AEs) of interest in the Target Trial Emulation Cohort and All Epcoritamab Cohort. Selected AEs of interest that require medical attention (i.e., hospitalization, ED visit, clinic visit, or dose delay) include:
a. All grade ICANS, TLS, and PML
b. Grade 2+ CRS
c. Grade 3+ infection, hematological toxicity
[Secondary Endpoint 3]
Proportion of AE of interest (with grade)

Key inclusion criteria

1. Adult patients (>=18 years of age) at the date of initiating epcoritamab (index date)
2. Documented CD20+ mature B-cell neoplasm with the following LBCL subtypes: DLBCL, FL (grade 3b), PMBCL, HGBCL, or other LBCL subtypes
3. R/R disease* and previously treated with 2 or more lines of systemic antineoplastic therapy including at least one anti-CD20 monoclonal antibody-containing therapy
*Relapsed disease is defined as disease that has recurred >=6 months after completion of therapy. Refractory disease is defined as disease that either progressed during therapy or progressed <6 months since completion of therapy
4. Initiated epcoritamab in the period between May 1, 2024 and Oct 31, 2025 and already initiated epcoritamab at the date of providing consent (or opt-out registration)
5. Provision of the patient's or the legally acceptable representative's informed consent. If the patient is deceased or lost to follow-up, and it is difficult to obtain appropriate consent from the patient or the legally acceptable representative, opt-out registration is permitted, only if the IRB/ IEC permits opt-out, in which the patient or the legally acceptable representative can access the opt-out information and are given the opportunity to refuse the provision of the patient existing information.

Key exclusion criteria

1. Patients who are deemed inappropriate for this study by the investigator
2. Patients who have participated in other clinical trials before epcoritamab and whose medical record data outside the trial period are not allowed to be collected for this study
3. Patients who participated in Epcoritamab-related clinical trials before Oct 31, 2025

This is a multicenter retrospective observational study utilizing medical charts collected from multiple clinical centers in Japan that treat patients with LBCL. In patients who initiated epcoritamab between May 1, 2024, and October 31, 2025, their treatment course will be observed retrospectively from the date of initial LBCL diagnosis, with the data cutoff date set as April 30, 2026.
Study population (i.e., All Epcoritamab Cohort) plans to include 300 patients with 3L+ R/R LBCL treated with epcoritamab at 30 clinical centers in Japan.
Study objectives will be evaluated in (1) All Epcoritamab Cohort and (2) Target Trial Emulation Cohort.
Among (1) All Epcoritamab Cohort, patients who meet the additional eligibility criteria below will also be incorporated in (2) Target Trial Emulation Cohort.

Additional criteria for (2) Target Trial Emulation Cohort.
Inclusion criteria:
1. Failed previous ASCT, or ineligible to ASCT due to age, performance status, comorbidities, and/or insufficient response to prior treatment
2. ECOG PS 0-2 at initiating epcoritamab
3. At least one response assessment after the initiation of epcoritamab
Exclusion criteria:
1. Primary CNS lymphoma or lymphoma with CNS involvement
2. Known past or current malignancy of any type other than inclusion diagnosis, except for any curative cancer with a CR of >2 years duration
3. Known clinically significant cardiovascular disease
4. Known HIV infection
When statistically analyzed, the (2) Target Trial Emulation cohort will be balanced to be similar to the cohort of patients with aNHL enrolled in the EPCORE NHL-1 trial (ClinicalTrials.gov: NCT03625037) based on key patient characteristics.

In addition to the primary and secondary endpoints described above, some items, including demographics, clinical characteristics, treatment regimens before and after epcoritamab, prophylactic treatment and concomitant medication, and LBCL-related HCRU, will be evaluated exploratorily.
