Diffuse Large B-cell Lymphoma Clinical Trial

Official title: A Pivotal Phase II Randomised, Multi-centre, Open-label Study to Evaluate the Efficacy and Safety of MB-CART2019.1 Compared to SoC Therapy in Participants With r/r DLBCL, Who Are Not Eligible for HDC and ASCT

Status Recruiting

Clinical Trial Summary

This is a pivotal Phase II randomised, multi-centre, open-label study to evaluate the efficacy and safety of MB-CART2019.1 compared to standard of care therapy in participants with relapsed/refractory diffuse large B-cell lymphoma, who are not eligible for high-dose chemotherapy and autologous stem cell transplantation.

Clinical Trial Description

This study should determine superiority of MB-CART2019.1 treatment compared to SoC therapy with R-GemOx (rituximab, gemcitabine and oxaliplatin) with respect to event-free survival in second-line therapy in participants with R-R DLBCL, who are non-eligible for high-dose chemotherapy and autologous stem cell transplantation.

MB-CART2019.1 is designed to effectively target malignant B cells in patients suffering from late stage haematological B-cell malignancies. MB-CART2019.1 consists of autologous cluster of differentiation CD20/CD19 chimeric antigen receptor (CAR) transduced CD4/CD8 enriched T cells, derived from a leukapheresis and processed by using the CliniMACS Prodigy®. Patients who are suitable for this study will be randomized 1:1 to either MB-CART2019.1 or SoC. Both treatment arms are unblinded.

MB-CART2019.1 arm: Single infusion of fresh formulation of 2.5 × 10^6 CAR-transduced autologous T cells. IMP is only to be administered after a lymphodepleting chemotherapy with fludarabine and cyclophosphamide. For MB-CART2019.1 production, patients will undergo a leukapheresis.

SoC arm: R-GemOx (8 cycles of 14 days each) or (10% of SoC arm) BR (Bendamustine/Rituximab) + polatuzumab vedotin (6 cycles of 21 days each). Participants from the SoC arm are allowed to be treated with MB-CART2019.1 upon request by the investigator if at least one of the following criteria is confirmed by the IRC:

• Relapse or progression occurring at any time within 1 year after randomisation.

• Failure to achieve PR or CR at or beyond Week 8 after randomisation (after 4 cycles of R-GemOx or 3 cycles of BR plus polatuzumab vedotin) and the start of a new anti-lymphoma therapy is warranted.

The duration of the active part of the study for each individual participant from screening to the end of the 1-year follow-up after infusion of MB-CART2019.1 cells (experimental arm) or the start of SoC therapy (comparator arm) will be approximately 55 weeks. The LTFU in Year 2 after infusion of MB-CART2019.1 cells or the start of treatment in the comparator arm will not be part of the active part of the clinical study and will be reported separately. ;
