Fresh tumour tissue for central pathology review must be provided as an adjunct to participation in this study. Should it not be possible to obtain a fresh tumour tissue sample, archival paraffin embedded tumour tissue acquired =3 years prior to screening for this protocol must be available for this purpose. 4. Patients must have: a) R-R DLBCL b) at least one bidimensionally measurable disease site. The lesion must have a greatest transverse diameter of =1.5 cm and greatest perpendicular diameter of =1.0 cm at baseline. The lesion must be positive on PET scan. c) received at least one, but no more than three previous systemic therapy lines for the treatment of DLBCL (for further details see Sections 8.6 and 9.5). At least one previous therapy line must have included a CD20-targeted therapy (e.g. RTX). d) Eastern Cooperative Oncology Group (ECOG) performance status of 0 to 2 5. Patients after failure of ASCT or patients considered in the opinion of the investigator currently not eligible for HDC with subsequent ASCT. Documentation of the reason for ineligibility for ASCT must be present in the patient’s source data. Laboratory Values 6. Patients must meet the following laboratory criteria at Screening: a) absolute neutrophil count (ANC) =1.5 × 10E9/L (unless secondary to bone marrow involvement by DLBCL as demonstrated by bone marrow aspiration and bone marrow biopsy required for Screening) b) platelet count =90 × 10E9/L (unless secondary to bone marrow involvement by DLBCL as demonstrated by bone marrow aspiration and bone marrow biopsy required for Screening) and absence of active bleeding c) total serum bilirubin =2.5 × upper limit of normal (ULN) unless secondary to Gilbert’s syndrome (or pattern consistent with Gilbert’s) or documented liver involvement by lymphoma. Patients with Gilbert's syndrome or documented liver involvement by lymphoma may be included if their total bilirubin is =5 x ULN (see exclusion criterion 6e) d) ALT, AST and alkaline phosphatase (AP) =3 × ULN or <5 × ULN in cases of documented liver involvement by lymphoma e) serum creatinine =2.0 x ULN or creatinine clearance must be =40 mL/min, calculated using a standard Cockcroft-Gault formula 7. For a female of childbearing potential (FCBP), a negative pregnancy test must be confirmed before enrolment. An FCBP must commit to take highly effective contraceptive precautions without interruption during the study and for 3, 6 or 12 months after the last dose of MOR00208, BEN or RTX respectively, whichever is later. An FCBP must refrain from breastfeeding and donating blood or oocytes during the course of the study and for 3, 6 or 12 months after the last dose of MOR00208, BEN or RTX respectively, whichever is later. Restrictions concerning blood donations apply as well to females
Exclusion criteria
Exclusion criteria: Exclusionary Diagnosis Criteria 1. Patients who have: a) any other histological type of lymphoma including, e.g., primary mediastinal (thymic) large B-cell (PMBL) or Burkitt’s lymphoma b) primary refractory DLBCL c) patients with known "double/triple hit" DLBCL genetics characterised by simultaneous detection of MYC with BCL2 and/or BCL6 translocation, as defined by fluorescence in situ hybridisation (FISH). MYC, BCL2, BCL6 testing prior to study enrolment is not required. d) central nervous system (CNS) lymphoma involvement in present or past medical history Exclusionary Previous and Current Treatment Criteria 2. Patients who had a major surgery (for definition, see Section 8.1) less than 30 days prior to Day 1 dosing 3. Patients who have, within 14 days prior to Day 1 dosing: a) not discontinued CD20-targeted therapy, chemotherapy, radiotherapy, investigational anticancer therapy or other lymphoma-specific therapy (for exceptions see Section 9.5.3) b) received live vaccines c) required parenteral antimicrobial therapy for active, intercurrent systemic infections 4. Patients who: a) in the opinion of the investigator, have not recovered sufficiently from the adverse toxic effects of prior therapies, major surgeries (for definition, see Section 8.1) or significant traumatic injuries b) were previously treated with CD19-targeted therapy or BEN c) have a history of previous severe allergic reactions to compounds of similar biological or chemical composition to MOR00208, RTX, murine proteins or BEN, or the excipients contained in the study drug formulations d) have undergone ASCT within a period of =3 months prior to signing the ICF. Patients who have a more distant history of ASCT must exhibit full haematological recovery before enrolment into the study. e) have undergone previous allogeneic stem cell transplantation f) concurrently use other anticancer or experimental treatments (for exceptions see Section 9.5.3) Exclusionary Medical History Criteria 5. Prior history of malignancies other than DLBCL, unless the patient has been free of the disease for =3 years prior to Screening. Exceptions to the =3-year time limit include history of the following: a) basal cell carcinoma of the skin b) squamous cell carcinoma of the skin c) carcinoma in situ of the cervix d) carcinoma in situ of the breast e) carcinoma in situ of the bladder f) incidental histological finding of prostate cancer (Tumour/Node/Metastasis [TNM] stage of T1a or T1b) 6. Patients with: a) positive hepatitis B and/or C serology b) known seropositivity for or history of active viral infection with human immunodeficiency virus (HIV) c) evidence of active, severe uncontrolled systemic infections (e.g., tuberculosis [TB], opportunistic infections) or sepsis d) a history or evidence of severely immunocompromised state e) a history or evidence of severe hepatic impairment (total serum bilirubin > 3 mg/dL), jaundice unless secondary to Gilbert's syndrome or documented liver involvement by lymphoma (see inclusion criterion 6c) f) a history or evidence of clinically significant cardiovascular, cerebrovascular, CNS and/or other disease that, in the investigator’s opinion, would preclude participation in the study or compromise the patient’s ability to give informed consent (for additional explanations, see Section 8.6).

| Main Objective: To determine the efficacy of a combination of MOR00208 with BEN versus a combination of RTX with BEN in terms of progression-free survival (PFS) in: • Adult patients with R-R DLBCL (overall population) • A subgroup of adult patients with R-R DLBCL with low baseline peripheral blood NK-cell count (NKCC-low), defined as 100 or less NK cells per µl blood at baseline. ;Secondary Objective: Secondary objectives will be assessed for the overall population, and NKCC-low subgroup, as appropriate. 1. To determine and compare both study arms, MOR00208 with BEN versus RTX with BEN, in terms of: a) best objective response rate (ORR = complete response [CR] + partial response [PR]) based on the best response achieved at any time during the study b) duration of response (DoR) c) overall survival (OS) d) disease control rate (DCR = CR + PR + stable disease [SD]) e) time to progression (TTP) f) time to next treatment (TTNT) g) safety, based on the frequency, incidence and severity of adverse events (AEs) h) quality of life (QoL), using the EORTC QLQ-C30 and EQ-5D-5L questionnaires 2. To assess the potential immunogenicity of MOR00208 (anti-MOR00208 antibody formation) 3. To assess the pharmacokinetic (PK) profile of MOR00208. ;Primary end point(s): Co-Primary Endpoints: 1.
