Radiation Priming Chimeric Antigen Receptor T-Cell Therapy in Relapsed/Refractory Diffuse Large B-Cell Lymphoma With High Tumor Burden

This study demonstrates that radiotherapy is an optimal debulking regimen to managing R/R DLBCL patients before CAR-T therapy and a promising alternative salvage therapy for patients who suffer a relapse after CAR-T therapy by fuelling CAR-T copies.

Publication date: Available online 2 October 2019Source: Clinical Lymphoma Myeloma and LeukemiaAuthor(s): Avyakta Kallam, Julie M. VoseAbstractNon-Hodgkin lymphomas that are refractory to or relapse after frontline chemoimmunotherapy have a poor prognosis. Although high dose chemotherapy, followed by autologous stem cell transplantation remains the standard of care at relapse, this treatment modality leads to a cure in less than 50% of the patients. Adoptive cellular immunotherapy with anti CD 19 chimeric antigen receptor (CAR) T cell has changed the treatment landscape in B cell lymphomas. They have emerged as effective t...

A promising and expensive type of immunotherapy, called CAR T-cell therapy, is now covered by Medicare. This news may affect mesothelioma patients in the future. Chimeric antigen receptor T-cell, or CAR T-cell, therapy involves the laboratory reprogramming of a patient’s T cells, which are a type of white blood cell responsible for protecting the body against infection and disease. The T cells are genetically modified to better recognize and attack cancer. The U.S. Food and Drug Administration has approved the immunotherapy procedure for non-Hodgkin lymphoma and B-cell precursor acute lymphoblastic leukemia. It is...

Follicular lymphoma (FL) is the second most common subtype of non-Hodgkin lymphoma. Follicular lymphoma is generally an indolent disorder, and despite being incurable with standard chemotherapy, recent advances in treatment strategies have improved clinical outcomes and survival. Over time, FL could acquire additional genetic mutations and transform into diffuse large B-cell lymphoma, a more aggressive B-cell neoplasm, which markedly reduces survival. Treatment of transformed FL is based on combination chemotherapy and immunotherapy. Rituximab has changed the treatment landscape in FL. However, novel approaches to treatmen...

High-dose chemotherapy and autologous stem cell transplantation (HDT-ASCT) is the standard of care for relapsed or primary refractory (rel/ref) chemorefractory diffuse large B-cell lymphoma. Only 50% of patients are cured with this approach. We investigated safety and efficacy of CD19-specific chimeric antigen receptor (CAR) T cells administered following HDT-ASCT. Eligibility for this study includes poor-risk rel/ref aggressive B-cell non-Hodgkin lymphoma chemosensitive to salvage therapy with: (1) positron emission tomography–positive disease or (2) bone marrow involvement. Patients underwe...

AbstractPurpose of ReviewIMiDs are a class of biologic agents with immunomodulatory, anti-angiogenic, and direct anti-cancer activities. This review summarizes current data on clinical development and application of IMiDs in non-Hodgkin lymphoma (NHL) subtypes, focusing primarily on lenalidomide, with additional discussion on managing common side effects.Recent FindingsImproved upon the prototype thalidomide, the second-generation compound lenalidomide has enhanced immunological and anti-cancer properties with fewer side effects, while next-generation small molecule cereblon/E3 ubiquitin ligase modulator CC-122 is in early...

CONCLUSIONS: In in-silico experiments, optimal protocols achieve significant gains over standard protocols when considering overall survival probabilities. Our optimization algorithm enables us to efficiently tackle this numerical problem with a large dimensionality. The in-vivo implications of our in-silico results remain to be explored.

CONCLUSION: While immunotherapy cannot be unequivocally incriminated in primary central nervous system lymphoma, this case raises many questions about the imputability of immunotherapy in the occurrence of secondary cancers, including lymphomas. PMID: 31122751 [PubMed - as supplied by publisher]

In conclusion, T cells from lymphoma patients are reduced in number and have functional defects following treatment with certain chemotherapy regimens, also reducing AFM11 efficacy. Importantly, AFM11 was still able to trigger B-cell-directed T-cell immunity in all treatment groups.

This article reviews novel immune therapies that have been used for the treatment of NHL. The data supporting the use of rituximab have been reviewed extensively; this article focuses on novel immunotherapies other than rituximab that remain in use or are actively being studied in clinical trials.
