Durability of complete response after blinatumomab therapy for relapsed/refractory diffuse large B-cell lymphoma
2020
Despite advances in standards of care, the prognosis of relapsed/refractory (R/R) diffuse large B-cell lymphoma (DLBCL) remains poor. In these patients, 50–74% fail to respond to next line therapy,...
Safety of the Anti-CD19 antibody Tafasitamab in Long Term Responders from A Phase II Trial for Relapsed Lymphoma
2022
Abstract Background: Information about the long-term tolerability of tafasitamab is still limited. Methods: 5 of 92 patients treated within a phase IIa study of single-agent tafasitamab in relapsed or refractory B NHL were followed for up to five years or longer for long-term tolerability. Results: Treatment was very well tolerated in an outpatient setting with no hospitalizations needed and mild and tolerable adverse events that occurred mostly within the first two years of treatment. Conclusions: Given the excellent tolerability and efficacy of tafasitamab this agent can be used to induce remission in relapsed or refractory lymphoma either alone or in combination with chemotherapy.

Host Genetic Background and Risk of Richter Syndrome: The Genotype of LRP4 Is An Independent Predictor of Chronic Lymphocytic Leukemia Transformation…
2009
Abstract Abstract 2340 Poster Board II-317 Richter syndrome (RS) represents the transformation of chronic lymphocytic leukemia (CLL) to aggressive lymphoma, most commonly diffuse large B-cell lymphoma (DLBCL). Mechanisms and risk factors of CLL transformation to RS are known only in part. This study aimed at exploring the role of the host genetic background in RS transformation and was based on a consecutive series of 331 CLL, of which 21 had transformed to RS (all clonally related to the CLL clone). Twenty eight additional cases of clonally related RS were also collected for validation purposes. Using an educated guess approach, SNPs were selected according to the following criteria: i) re…
A Phase IIa, Open-Label, Multicenter Study of Single-Agent Tafasitamab (MOR208), an Fc-Optimized Anti-CD19 Antibody, in Patients with Relapsed or Ref…
2019
Background: CD19 is broadly and homogeneously expressed across different B-cell malignancies and represents an attractive target antigen in patients with B-cell non-Hodgkin's lymphoma (NHL). Tafasitamab (MOR208) is an Fc-enhanced, humanized, anti-CD19 monoclonal antibody. This ongoing study is investigating the single agent antitumor activity in adult patients with relapsed or refractory (r/r) NHL who had received at least one prior rituximab-containing therapy. Patients and Methods: The study enrolled 92 r/r NHL patients: diffuse large B-cell lymphoma (DLBCL; n=35), mantle cell lymphoma (MCL; n=12), follicular lymphoma (FL; n=34), or other indolent NHL (iNHL; n=11). The median number of pr…
Tafasitamab Plus Lenalidomide Versus Pola-BR, R2, and CAR T: Comparing Outcomes from RE-MIND2, an Observational, Retrospective Cohort Study in Relaps…
2021
Abstract Background Several therapies are recommended by NCCN/ESMO guidelines for autologous stem cell transplant (ASCT)-ineligible patients with relapsed/refractory (R/R) diffuse large B-cell lymphoma (DLBCL). In the single-arm, Phase II L-MIND study (NCT02399085), the chemotherapy-free regimen tafasitamab + lenalidomide (LEN) demonstrated efficacy for this patient population. In the absence of randomized clinical trial data, RE-MIND2 (NCT04697160), an observational, retrospective cohort study, compared patient outcomes from L-MIND with matched patient populations treated with NCCN/ESMO recommended therapies for ASCT-ineligible patients with R/R DLBCL. Methods Data were retrospectively col…
Diffuse large B-cell lymphoma, not otherwise specified of the palate: A case report
2013
Diffuse large B-cell lymphoma (DLBCL) is the most frequent type of non-Hodgkin´s lymphoma found in oral and maxillofacial regions. A large number of cases may be biologically heterogeneous, which are commonly defined as DLBCL, not otherwise specified (NOS) by the World Health Organization (WHO-2008). The present case reports on an ulcer of raised and irregular edges, found on the border between the hard and soft palate, as the first and only manifestation of an extranodal non-Hodgkin lymphoma in an 85-year-old patient. Incisional biopsy was carried out, and the specimen revealed a proliferation of large lymphoid cells suggestive of diffuse large cell lymphoma. An immunohistochemical analysi…
Spatial transcriptome of a germinal center plasmablastic burst hints at MYD88/CD79B mutants-enriched diffuse large B-cell lymphomas
2022
The GC reaction results in the selection of B cells acquiring effector Ig secreting ability by progressing toward plasmablastic differentiation. This transition is associated with exclusion from the GC microenvironment. The aberrant expansion of plasmablastic elements within the GC fringes configures an atypical condition, the biological characteristics of which have not been defined yet. We investigated the in situ immunophenotypical and transcriptional characteristics of a nonclonal germinotropic expansion of plasmablastic elements (GEx) occurring in the tonsil of a young patient. Compared to neighboring GC and perifollicular regions, the GEx showed a distinctive signature featuring key r…
Evaluation of the impact of therapeutic management on the survival and quality of life of patients with follicular lymphoma or diffuse large B cell l…
2014
In France, hematologic malignancies, which are the sixthmost common cancers, are amajor public healthproblem. This work aimed to study the impact of the therapeutic management on survival and healt-relatedquality of life (HRQoL) in patients with these hematologic malignancies. The first objective of this work is topresent an overview of the epidemiology of lymphoid malignancies with a study of changes in the incidenceand net survival in the Côte d’Or department between 1980 and 2009. The incidence, which has increased since1980, seems to have stabilized since the 2000s for some entities, including follicular lymphoma (FL) and diffuselarge B-cell lymphoma (DLBCL). Overall, we observed an imp…
Patterns of oncogene co-expression at single cell resolution in cancer influence survival
2020
AbstractBackgroundCancers often overexpress multiple clinically relevant oncogenes. However, it is not known if multiple oncogenes within a cancer combine uniquely in specific cellular sub-populations to influence clinical outcome. We studied this phenomenon using the prognostically relevant oncogenes MYC, BCL2 and BCL6 in Diffuse Large B-Cell Lymphoma (DLBCL).MethodsQuantitative multispectral imaging simultaneously measured oncogene co-expression at single-cell resolution in reactive lymphoid tissue (n=12) and four independent cohorts (n=409) of DLBCL. Mathematically derived co-expression phenotypes were evaluated in DLBCLs with immunohistochemistry (n=316) and eight DLBCL cohorts with gen…
