A Trial to Evaluate the Efficacy and Safety of Tafasitamab With Bendamustine (BEN) Versus Rituximab (RTX) With BEN in Adult Patients With Relapsed or Refractory Diffuse Large B-cell Lymphoma (DLBCL)

Best ORR was defined as the percentage of patients with complete response (CR) or partial response (PR) based on the best response achieved at any time during the study. Per International Working Group response criteria: CR: the disappearance of all evidence of disease; PR: regression of measurable disease and no new sites.

Duration of response was defined as the elapsed time (in months) between the date of the first documented response (CR or PR) and the following date of an event defined as the first documented progression (any new lesion or an increase by ≥50% of previously involved sites from nadir) or death. Per International Working Group response criteria: CR: the disappearance of all evidence of disease; PR: regression of measurable disease and no new sites.

Overall survival was defined as the time (in months) from randomization until death from any cause.

Overall survival was defined as the time (in months) from randomization until death from any cause.

DCR was defined as the percentage of participants with a CR, PR, or stable disease (SD) based on the best response achieved at any time during the study. Per the International Working Group response criteria: CR: the disappearance of all evidence of disease; PR: regression of measurable disease and no new sites; SD: failure to attain CR/PR or progressive disease (PD; any new lesion or an increase by ≥50% of previously involved sites from nadir).

Time to progression was defined as the time (in months) from randomization until documented diffuse large B-call lymphoma (DLBCL) progression or death as a result of lymphoma. Death from other causes than lymphoma was not considered in relation to the TTP evaluation.

Time to progression was defined as the time (in months) from randomization until documented diffuse large B-call lymphoma (DLBCL) progression or death as a result of lymphoma. Death from other causes than lymphoma was not considered in relation to the TTP evaluation.

Time to next treatment was defined as the time (in months) from randomization to the institution of the next anti-neoplastic therapy (for any reason including disease progression, treatment toxicity, and participant preference) or death due to any cause, whatever came first.

Time to next treatment was defined as the time (in months) from randomization to the institution of the next anti-neoplastic therapy (for any reason including disease progression, treatment toxicity, and participant preference) or death due to any cause, whatever came first.

An adverse event was defined as any untoward medical occurrence in a participant administered a medicinal product, which did not necessarily have a causal relationship to this treatment. An AE could therefore have been any unfavourable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a study drug, whether or not it was considered related to that study drug. TEAEs were defined as any adverse events either reported for the first time or the worsening of pre-existing events after the first dose of study drug and within 30 days of the last administration of study drug.

AEs were graded according to the National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE), version 4.0 (or higher). Grade 1: mild; asymptomatic or mild symptoms. Grade 2: moderate. Grade 3: severe or medically significant but not immediately life threatening. Grade 4: life-threatening consequences. Grade 5: death. TEAEs were defined as any adverse events either reported for the first time or the worsening of pre-existing events after the first dose of study drug and within 30 days of the last administration of study drug.

The European Organization for the Research and Treatment of Cancer Core Quality of Life Questionnaire (EORTC QLQ-C30) contains 30 items and measures 5 functional dimensions (i.e., physical, role, emotional, cognitive, and social), 3 symptom items (i.e., fatigue, nausea/vomiting, and pain), 6 single items (i.e., dyspnea, sleep disturbance, appetite loss, constipation, diarrhea, and financial impact), and a global health and quality of life scale. For each scale and single item, a linear transformation was applied to standardize the scores between 0 (worst) and 100 (best) as described in the EORTC QLQ-C30 Scoring Manual.

The EQ-5D-5L is a standardized instrument for use as a measure of health outcome. The EQ-5D-5L descriptive system is composed of 5 dimensions (mobility, self-case, usual activities, pain/discomfort, and anxiety/depression). Each dimension has 5 response levels, which are coded by single-digit numbers: 1 = no problems, 2 = slight problems, 3 = moderate problems, 4 = severe problems, 5 = unable to/extreme problems. The EQ-5D-5L also includes a graded (0 [worst overall health] to 100 [best overall health]) vertical visual analog scale that provides a quantitative measure of the participant's perception of their overall health.
