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) (B-MIND)

A Phase 2/3, Randomised, Multicentre Study of Tafasitamab With Bendamustine Versus Rituximab With Bendamustine in Patients With Relapsed or Refractory Diffuse Large B-Cell Lymphoma (R-R DLBCL) Who Are Not Eligible for High-Dose Chemotherapy (HDC) and Autologous Stem-Cell Transplantation (ASCT)

The purpose of the study is to compare the safety and efficacy of Tafasitamab with BEN versus RTX with BEN in adult patients with relapsed of refractory DLBCL.

Study Overview

• Status: Completed
• Conditions: Diffuse Large B-cell Lymphoma
• Intervention / Treatment: Drug: Tafasitamab; Drug: Bendamustine (BEN); Drug: Rituximab (RTX)

Detailed Description

This is a randomised, two-arm, multicentre, open-label phase II/III efficacy and safety study of Tafasitamab in combination with BEN versus RTX in combination with BEN given to adult patients who have relapsed after or are refractory to at least one but no more than three prior systemic therapies and have failed, or are not candidates for HDC and ASCT, and have thus exhausted their therapeutic options of demonstrated clinical benefit. At least one prior therapy line must have included a CD20-targeted therapy.

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.	up to 77 months
Change From Baseline (CFB) in the EORTC QLQ-C30 Scores at End of Treatment in the Overall Population	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.	Baseline; End of Treatment (EOT) (up to 77 months)
Change From Baseline (CFB) in the EORTC QLQ-C30 Scores at End of Treatment in the Natural Killer Cell Count-Low Subgroup	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.

Change From Baseline (CFB) in EQ-5D-5L Dimension Scores at End of Treatment in the Overall Population	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.
