Early treatment intensification in patients with high risk Mantle Cell Lymphoma using CAR-T-cell treatment after an abbreviated induction therapy with Rituximab and Ibrutinib and 6 months Ibrutinib maintenance (Arm A) as compared to standard of care induction and maintenance (Arm B)
Arm A (experimental): The abbreviated induction phase consists of 2 cycles of Ibrutinib + Rituximab and 2 cycles of Ibrutinib + R-CHOP for primary tumor reduction followed by CAR-T-cell treatment. In case of good clinical response (PR or CR) after 2 cycles of Ibrutinib + Rituximab, Ibrutinib + R-CHOP can be omitted. In this case, one cycle of Ibrutinib monotherapy will be applied. T cell apheresis will be performed after the initial 2 cycles. Application of KTE-X19 will be performed after lymphodepleting chemotherapy with Fludarabine and Cyclophosphamide (FC). After stable hematopoietic recovery, maintenance with Ibrutinib will be applied for 6 months but not prior to day 60 post CAR. The follow-up period starts after the completion of Ibrutinib maintenance and takes 4.5 up to 7 years.
Arm B (control): Younger patients (d 65 years) will receive 3 cycles R-CHOP + Ibrutinib/ 3 cycles R-DHAP alternating, followed by autologous stem cell transplantation (ASCT). Elderly patients (e 65 years) will receive 6 cycles of Bendamustine and Rituximab + Ibrutinib or R-CHOP + Ibrutinib without ASCT. Independently of age, control patients receive 2 years of maintenance therapy with Ibrutinib and 3 years of Rituximab maintenance if foreseen by national guidelines, in addition to Ibrutinib maintenance.
