Late Non-Relapse Mortality (NRM) after Standard-of-Care (SOC) CAR-T Cell Therapy for Large B-Cell Lymphoma (LBCL): Frequency, Causes, and Risk Factor…
2021
Abstract Introduction Although the labeled CD19 targeting CAR-T cell constructs axi-cel and tisa-cel are generally associated with an acceptable safety profile, non-relapse deaths can occur. Little is known about timing, causes and predictors of NRM following SOC CAR-T cell therapy for LBCL. Here, we analyzed frequency, causes, and risk factors of non-relapse deaths with focus on late NRM (beyond 4 weeks after dosing) using registry data provided by the DRST, the national partner of the EBMT. Methods Patients were selected from 356 consecutive patients who received SOC CAR-T treatment of LBCL between November 2018 and April 2021 at 21 German centers and were registered with the DRST/EBMT. B…
Polatuzumab vedotin as a salvage and bridging treatment in relapsed or refractory large B-cell lymphomas
2021
The antibody-drug conjugate polatuzumab vedotin (pola) has recently been approved in combination with bendamustine and rituximab (pola-BR) for patients with refractory or relapsed (r/r) large B-cell lymphoma (LBCL). To investigate the efficacy of pola-BR in a real-world setting, we retrospectively analyzed 105 patients with LBCL who were treated in 26 German centers under the national compassionate use program. Fifty-four patients received pola as a salvage treatment and 51 patients were treated with pola with the intention to bridge to chimeric antigen receptor (CAR) T-cell therapy (n = 41) or allogeneic hematopoietic cell transplantation (n = 10). Notably, patients in the salvage and brid…
Superiority of the Triple Combination of Bortezomib-Thalidomide-Dexamethasone Over the Dual Combination of Thalidomide-Dexamethasone in Patients With…
2012
Purpose This prospective multicenter phase III study compared the efficacy and safety of a triple combination (bortezomib-thalidomide-dexamethasone [VTD]) versus a dual combination (thalidomide-dexamethasone [TD]) in patients with multiple myeloma (MM) progressing or relapsing after autologous stem-cell transplantation (ASCT). Patients and Methods Overall, 269 patients were randomly assigned to receive bortezomib (1.3 mg/m2 intravenous bolus) or no bortezomib for 1 year, in combination with thalidomide (200 mg per day orally) and dexamethasone (40 mg orally once a day on 4 days once every 3 weeks). Bortezomib was administered on days 1, 4, 8, and 11 with a 10-day rest period (day 12 to day …
Polatuzumab Vedotin in Relapsed and Refractory (r/r) Large B-Cell Lymphoma (LBCL): Real-World Data of the German National Compassionate Use Program (…
2020
Introduction The antibody-drug conjugate polatuzumab vedotin (Pola) has recently been approved in combination with bendamustine and rituximab (Pola-BR) for patients with r/r diffuse LBCL (DLBCL). Methods To characterize the efficacy of Pola-BR in a real-world setting, we retrospectively analyzed data from 97 patients with r/r LBCL who were treated with Pola in 24 German centers within the national CUP. Clinical baseline and follow-up (FU) data were collected by chart review and summarized descriptively. Progression-free survival (PFS) and overall survival (OS) were analyzed using Kaplan-Meier and Cox regression methods. Fisher's exact test was used to compare categorical factors between gro…
Comparison of Allogeneic Stem Cell Transplantation for Transformed Acute Myeloid Leukemia Derived from MDS, CMML or MPN. a Report of the Chronic Mali…
2016
Abstract Introduction Myelodysplastic syndromes (MDS), myeloproliferative neoplasms (MPN) and chronic myelomonocytic leukemia (CMML) can progress to acute myeloid leukemia (transformed AML). The aim of this EBMT registry study was to compare 3 year outcome in patients with transformed AMLwho received allogeneic stem cell transplantation according to the primary disease. Patients and Methods Within the European Society of Blood and Marrow Transplantation (EBMT) registry, we found 4214 patients (female: 39%, male: 61%) with transformed acute myeloid leukemia, who received allogeneic stem cell transplantation between 2000 and 2014. The primary disease was MDS (n=3541), CMML (n=251) or MPN (n=4…
Standard of Care CAR-T Cell Therapy for Large B-Cell Lymphoma (LBCL): Does Bridging Efficacy Matter? a German GLA/DRST Real World Analysis
2021
Abstract Introduction The CD19 targeting CAR-T cell constructs axicabtagene ciloleucel (axi-cel) and tisagenlecleucel (tisa-cel) have become an accepted standard salvage treatment of LBCL beyond the second line. Patients scheduled for approved CAR-T cell therapies usually have 4-8 weeks wait time for CAR-T cell infusion, thus often requiring bridging strategies in rapidly progressing patients to achieve disease control until start of lymphodepletion. It is still unclear, however, if the adverse impact of active progressive lymphoma can be overcome by successful bridging. We have addressed this question using registry data provided by the German Registry for Stem Cell Transplantation (DRST),…
Treatment of Newly Diagnosed Moderate or Severe Chronic Graft-Versus-Host Disease with Prednisone and Everolimus (PredEver first): A Prospective Mult…
2019
Background Chronic graft-versus-host disease (cGVHD) is the major cause of treatment related morbidity and mortality after allogeneic stem cell transplantation (allo-HSCT). Recently Paul Martin et al. reported that treatment success at 1 year (defined as a patient being in partial (PR) or complete remission (CR) of cGVHD, in ongoing remission of underlying disease and not requiring any secondary treatment for cGVHD) was the only endpoint associated with clinical benefit. Strikingly this robust endpoint was only achieved in less than 20% of patients undergoing primary treatment for cGVHD. Therefore, although most patients show initial response to first-line therapy, long-term clinically mean…
