Polatuzumab vedotin (polatuzumab vedotin-piiq; Polivy™) is an antibody-drug conjugate comprising a monoclonal antibody against CD79b (a B cell receptor component) covalently conjugated to the anti-mitotic cytotoxic agent monomethyl auristatin (MMAE) via a cleavable linker. After binding to CD79b on the B-cell surface, polatuzumab vedotin is internalized and the linker is cleaved, releasing MMAE into the cell, where it inhibits division and induces apoptosis. Polatuzumab vedotin is being developed by Genen...
The purpose of this study was to investigate effect of plasma-derived exosomes of refractory/relapsed or responsive diffuse large B-cell lymphoma (DLBCL) patients on natural killer (NK) cell functions.
Although treatments for adult T-cell leukemia/lymphoma in the past two decades have advanced, the current standard treatment for aggressive adult T-cell leukemia/lymphoma, particularly in patients who are not eligible for stem cell transplantation, remains inadequate; therefore, treatments to prolong the duration of remission and provide relevant benefits in terms of survival and quality of life are needed. Adult T-cell leukemia/lymphoma tumor cells express CD30 in some cases and the increased expression of...
Diffuse large B-cell lymphomas (DLBCLs) and follicular lymphoma (FL) are the most common subtypes of B-cell non-Hodgkin's lymphomas in adults. Histologic transformation of FL to DLBCL (TFL) occurs in approximately 15% of patients and is generally associated with a poor clinical outcome. Phosphatidylinositol 3-kinase (PI3K) inhibitors have shown promising results in the treatment of relapsed/refractory FL. CAR T-cell therapy (axicabtagene ciloleucel and tisagenlecleucel) has emerged as a novel treatment opti...
Primary mediastinal B-cell lymphoma (PMBL) is a rare but aggressive non-Hodgkin lymphoma with poor outcomes in patients with relapsed/refractory (R/R) disease. PMBL is characterized by high expression of programmed death-1 ligand and variable expression of CD30. Nivolumab, an anti-programmed death-1 immune checkpoint inhibitor, and brentuximab vedotin (BV), an anti-CD30 antibody-drug conjugate, may have synergistic activity in R/R PMBL.
Allogeneic stem cell transplant (alloSCT) is considered in diffuse large B cell lymphoma (DLBCL) patients with chemorefractory disease or who have relapsed following autologous stem cell transplant (autoSCT). Here we present the first report of alloSCT using R-BEAM conditioning regimen in DLBCL patients.
Patients with relapsed or refractory primary mediastinal large B-cell lymphoma (rrPMBCL) have a poor prognosis, and their treatment represents an urgent and unmet need. Because PMBCL is associated with genetic aberrations at 9p24 and overexpression of programmed cell death-1 (PD-1) ligands (PD-L1), it is hypothesized to be susceptible to PD-1 blockade.
Double/triple-hit lymphomas (DHL/THL), also known as high-grade B-cell lymphoma with MYC and BCL2 and/or BCL6 rearrangements, are associated with chemoresistance and inferior survival. However, whether RT efficacy is altered in DHL/THL is less well characterized. Among patients with relapsed/refractory (R/R) large B-cell lymphoma (LCBL), we compared rates and durability of response between patients with and without DHL/THL.
Pembrolizumab monotherapy in patients with primary refractory classical hodgkin lymphoma who relapsed after salvage autologous stem cell transplantation and/or brentuximab vedotin therapy: KEYNOTE-087 subgroup analysis.
Outcomes for patients with relapsed/refractory acute myeloid leukemia (R/R AML) remain poor. Novel therapies specifically targeting AML are of high interest. Brentuximab vedotin (BV) is an antibody-drug conjugate that is specific for human CD30. In this phase 1 dose escalation study, the authors evaluated the safety of BV combined with mitoxantrone, etoposide, and cytarabine (MEC) re-induction chemotherapy for patients with CD30-expressing R/R AML.
To investigate the use of high-dose therapy and autologous stem cell transplantation (ASCT) for relapsed or high-risk diffuse large B-cell lymphoma (DLBCL) between 1990 and 2007, we conducted a nationwide survey using the registry database of the Japan Society for Hematopoietic Cell Transplantation. Of the 1222 patients in the database, 576 (47%) received ASCT in first complete remission (CR1), 140 (12%) in first partial remission, 281 (23%) in sensitive relapse, 150 (12%) in resistant or sensitivity-unknow...
Chimeric antigen receptor T-cell (CAR-T) therapy demonstrates impressive efficacy in relapsed/refractory (R/R) diffuse large B-cell lymphoma (DLBCL). However, CAR-T therapy-related severe cytokine release syndrome and neurological toxicity limit its clinical application in R/R DLBCL patients with high tumor burden. Here, we conducted a phase II clinical trial testing the efficacy and toxicities of CAR-T therapy in R/R non-Hodgkin lymphoma patients (NCT03196830). Among the enrolled patients, 10 R/R DLBCL pat...
To date, breakthrough chimeric antigen receptor (CAR) T-cell therapies, such as tisagenlecleucel, indicated for pediatric acute lymphoblastic leukemia (pALL) and diffuse large B-cell lymphoma (DLBCL), and axicabtagene ciloleucel, indicated for DLBCL, although clinically effective, have been limited by treatment delays. Our study measured the social value of CAR T-cell therapy (CAR T) for relapsed or refractory pALL and DLBCL in the United States and quantified social value lost due to treatment delays.
Patients with relapsed or refractory acute myeloid leukemia (AML) with mutations in the FMS-like tyrosine kinase 3 gene () infrequently have a response to salvage chemotherapy. Gilteritinib is an oral, potent, selective FLT3 inhibitor with single-agent activity in relapsed or refractory -mutated AML.
: Primary mediastinal (thymic) large B-cell lymphoma (PMBCL) is an uncommon subtype of diffuse large B-cell lymphoma. Approximately 10-30% of patients experience refractory or relapsed PMBCL (rrPMBCL) after first-line therapy. Data and treatment guidelines for rrPMBCL are scarce, and management is based on clinical experience.: Two structured literature reviews were undertaken to determine the incidence, prevalence, and mortality rates associated with rrPMBCL, and to identify clinical practice guidelines an...
While various tools such as the International Prognostic Index (IPI) and its derivatives exist for risk-stratification in DLBCL at diagnosis, patient and disease characteristics capable of predicting outcome after high-dose chemotherapy followed by autologous stem cell transplantation (HDC/ASCT) are not clearly defined. We retrospectively analyzed medical records of 111 DLBCL patients (78 relapsed, 33 refractory) who underwent HDC/ASCT at our institution from 2010-2015. After a median follow-up time of 4.6 ...
Immunotherapies targeting CD19 (blinatumomab) and CD22 (inotuzumab ozogamicin) have demonstrated higher complete response rates and improved survival compared with chemotherapy in relapsed/refractory acute lymphoblastic leukemia (ALL), and are now standard of care in the relapsed setting. However, most adult patients still die of ALL despite these therapies, with or without hematopoietic stem cell transplant. At the NCCN 2019 Annual Congress: Hematologic Malignancies, Dr. Jae Park summarized clinical data f...
Alectinib, an anaplastic lymphoma kinase (ALK) inhibitor, as a bridge to allogeneic stem cell transplantation in a patient with ALK-positive anaplastic large-cell lymphoma refractory to chemotherapy and brentuximab vedotin.
This is the first case report of alectinib as a bridge to allo-SCT in a patient with ALK-positive ALCL refractory to both conventional chemotherapies and BV. This report offers a ray of hope for a condition with poor prognosis.
For patients with primary refractory and relapsed acute leukaemias allogeneic stem cell transplantation is the only hope for cure, but morphological remission is not always achieved after standard salvage regimens. Here we review the experience with high-dose etoposide and cyclophosphamide (HD-Et/Cy) in relapsed/refractory acute leukaemias at the Royal Marsden Hospital.
The development of chimeric antigen receptor (CAR) T-cell therapy for select hematological malignancies represents one of the most remarkable therapeutic advances in the past decade. Currently, CD19-targeted CAR T-cell therapy is approved for relapsed/refractory diffuse large B cell lymphoma and acute lymphoblastic leukemia. However, there is significant interest in the application of CAR T-cell therapy to other hematological malignancies, including multiple myeloma, where the current focus is on the develo...
The outcome of relapsed/refractory HIV-associated lymphoma remains poor, even in the era of combined antiretroviral therapy. However, recent reports showed the efficacy of autologous stem cell transplantation (ASCT). We conducted a single-arm, multicenter phase II study in patients with relapsed/refractory HIV-associated lymphoma to assess the safety and efficacy of ASCT. The study included 14 patients with relapsed/refractory HIV-associated lymphoma. Five patients who achieved partial remission or better a...
High-dose cyclophosphamide to treat solid refractory tumors demonstrated meaningful activity, while data to treat lymphoma remains scarce. This study aims to assess high-dose cyclophosphamide to treat relapsed or refractory lymphoma.
