Salvage Therapy With Polatuzumab Vedotin, Bendamustine, and Rituximab Prior to Allogeneic Hematopoietic Transplantation in Patients With Aggressive Lymphomas Relapsing After Therapy With Chimeric Antigen Receptor T-Cells—Report on Two Cases

Gerhardt, Kristin, Jentzsch, Madlen, Georgi, Thomas, Sretenovi´c, Aleksandra, Cross, Michael, Bach, Enrica, Monecke, Astrid, Leiblein, Sabine, Hoffmann, Sandra, Todorovi´c, Milena, Bila, Jelena, Sabri, Osama, Schwind, Sebastian, Franke, Georg-Nikolaus, Platzbecker, Uwe, Vucˇ ini´c, Vladan 30 March 2023 (has links)
Up to 60% of patients with aggressive B-cell lymphoma who receive chimeric antigen receptor (CAR) T-cell therapy experience treatment failure and subsequently have a poor prognosis. Allogeneic hematopoietic stem cell transplantation (alloHSCT) remains a potentially curative approach for patients in this situation. Induction of a deep response prior to alloHSCT is crucial for long-term outcomes, but the optimal bridging strategy following relapse after CAR T-cell therapy has not yet been established. Polatuzumab vedotin, an antibody drug conjugate targeting CD79b, is a novel treatment option for use in combination with rituximab and bendamustine (Pola-BR) in relapsed or refractory disease. Patients: We report two heavily pretreated patients with primary refractory diffuse large Bcell lymphoma (DLBCL) and primary mediastinal B-cell lymphoma (PMBCL) respectively who relapsed after therapy with CAR T-cells with both nodal and extranodal manifestations of the disease. After application of three courses of Pola-BR both patients achieved a complete metabolic remission. Both patients underwent alloHSCT from a human leukocyte antigen (HLA)-mismatched donor following conditioning with busulfan and fludarabine and are disease free 362 days and 195 days after alloHSCT respectively. We conclude that Pola-BR can be an effective bridging therapy before alloHSCT of patients relapsing after CAR T-cell therapy. Further studies will be necessary to define the depth and durability of remission of this salvage regimen before alloHSCT.

Objetivos: Descrever o perfil e as complicações agudas mais importantes das crianças que receberam transplante de medula óssea (TMO) em nosso Serviço. Casuística e métodos: Análise retrospectiva de 41 pacientes menores de 21 anos transplantados entre Agosto de 1997 até Junho de 2002. Deste total 20 receberam transplante alogênico e 21 receberam transplante autogênico. Resultados: No TMO alogênico a média de idade foi de 8,9 + 5,4 anos, sendo 12 pacientes do sexo masculino. As fontes de células foram: medula óssea (MO) 12, sangue periférico (SP) 5, sangue de cordão umbilical não aparentado (SCU) 3. As doenças tratadas foram leucemia linfóide aguda (LLA) 7 pacientes, leucemia linfóide crônica (LMC) 2; leucemia mielóide aguda (LMA) 4; Síndrome mielodisplásica 2; Linfoma de Burkitt 1, Anemia aplástica grave 1; Anemia de Fanconi 1; Síndrome Chediak Higashi 1; Imunodeficiência congênita combinada grave 1. Um paciente desenvolveu doença do enxerto contra hospedeiro (DECH) aguda grau 2 e três DECH grau 4. Três pacientes desenvolveram DECH crônica. Todos haviam recebido SP como fonte de células. A sobrevida global foi de 70,0 + 10,3%. A principal causa do óbito foi DECH em 3 pacientes e sépse em outros 3. Todos os óbitos ocorreram antes do dia 100. Um dos pacientes que recebeu SCU está vivo em bom estado e sem uso de medicações 3 anos e 6 meses pós TMO. No TMO autogênico, a média de idade foi de 8,7 + 4,3 anos, sendo 11 pacientes do sexo masculino. As fontes de células foram SP 16, MO 3, SP + MO 2. As doenças tratadas foram: tumor de Wilms 5; tumores da família do sarcoma de Ewing 4; neuroblastomas 3; linfomas de Hodgkin 3; rabdomiossarcomas 2, tumor neuroectodérmico primitivo do SNC 2; Linfoma não Hodgkin 1; LMA 1. A sobrevida global está em 59,4 + 11,7 %. Cinco óbitos tiveram como causa a progressão da doença de base, um óbito ocorreu devido à infecção 20 meses pós TMO e dois óbitos foram precoces por sépse. As toxicidades mais comuns em ambos os grupos foram vômitos, mucosite, diarréia e dor abdominal. Infecções foram documentadas em 58,5% dos pacientes e 46,9% tiveram no mínimo um agente isolado na hemocultura. Os tempos de enxertia de neutrófilos e plaquetas correlacionaram-se com o número de células progenitoras infundidas. Conclusão: A sobrevida de nossos pacientes é semelhante à encontrada na literatura de outros serviços nacionais e internacionais. Não encontramos diferença entre os dois tipos de transplante com relação às toxicidades agudas e ás infecções. / Objectives: To describe the demografics and the most important acute clinical complications of the patients who underwent bone marrow transplantation (BMT) at our Service. Material and methods: A Retrospective analysis was performed including 41 patients treated between August 1997 and June 2002. Twenty patients had a allogeneic BMT and 21 autologous BMT. Results: Regarding allogeneic BMT the mean age was 8.9 + 5.4 years. Twelve patients were male. The stem cells sources were: bone marrow (BM) 12, peripheral blood (PB) 5, unrelated cord blood (UCB) 3. The diseases were acute lymphoid leukemia (ALL) in 7 patients, acute myeloid leukemia (AML) 4, Chronic myeloid leukemia (CML) 2, myelodysplastic syndrome 2, Burkitt’s lymphoma 1, severe combined immunodeficiency 1, Chediaki Higashi 1, Fanconi anemia 1, aplastic anemia 1. One patient developed grade 2 acute graft versus host disease (GVHD) and 3 had grade 4. Three patients developed chronic GVHD. All of them received PB as cell source. The overall survival was 70.0 + 10.3%. The main cause of death was GVHD in 3 patients and sepsis in the 3 other ones. All deaths occurred before day 100. One of the patients who received UCB is alive 3.5 years after the transplantation. Regarding autologous BMT, the mean age was 8,7 + 4,3 years. Eleven patients were male. The stem cell sources were: PB 16, BM 3, PB + BM 2. The diseases were: Wilms tumor 5, Ewing’s sarcoma family tumors 4, neuroblastoma 3, Hodgkin’s disease 3, non-Hodgkin’s lymphoma 1, rhabdomiossarcoma 2, Neuroectodermic tumor of the central nervous system 2, AML 1. The overall survival was 59.4 + 11.7%. Five patients died due to tumor relapse, 2 patients due to sepsis and one patient died in remission 20 months after BMT due to infection. In the whole group the most common toxicities were vomiting, mucositis, diarrhea and abdominal pain. Infections were documented in 58.5% of the patients and 46.9% had at least one agent isolated in the blood culture. The time to neutrophil and platelet engraftment were correlated to the number of hematopoietic stem cell infused. Conclusion: The overall survival in our patients is similar to the reported on the literature. We did not find differences between autologous and allogeneic BMT, regarding acute toxicities and infections.
