Metabolic profile evolution in relapsed/refractory B-cell non-Hodgkin lymphoma patients treated with CD19 chimeric antigen receptor T-cell therapy and implications in clinical outcome.

Plasma metabolomics analysis was performed on 44 patients with relapsed/refractory B-cell non-Hodgkin lymphoma (r/r/B-NHL) infused with approved CD19.CAR-T cell products at the time of pre-lymphodepletion (PLD) and at day +1, +7, and +30 after CAR-T cell infusion. At the PLD time point, a metabolic profile characterized by high lipoproteins and lactate and low glucose contributed to poor outcome prediction in association with high lactate dehydrogenase levels.

A Phase 2 study of acimtamig (AFM13) in patients with CD30-positive, relapsed or refractory peripheral T-cell lymphomas.

Background: Patients with relapsed or refractory (R/R) peripheral T-cell lymphoma (PTCL) generally have poor prognoses and limited treatment options.

Materials & Methods: This study evaluated the efficacy of a novel CD30/CD16A bispecific innate cell engager, acimtamig (AFM13), in patients with R/R PTCL. Patients included those with CD30 expression in ≥1% of tumor cells and who were R/R following ≥1 prior line of systemic therapy.

Loncastuximab tesirine in previously treated diffuse large B-cell lymphoma: A plain language summary of the LOTIS-2 study.

What Is This Summary About?: This article provides a plain-language summary of the results of a clinical trial called the LOTIS-2 study.The LOTIS-2 study included 145 participants with an aggressive type (one that forms, grows, or spreads quickly) of non-Hodgkin lymphoma called diffuse large B-cell lymphoma (a type of blood cancer), or DLBCL for short, whose disease came back or did not respond after 2 or more previous treatments. The LOTIS-2 study was conducted from August 2018 to September 2022.

Valemetostat for patients with relapsed or refractory peripheral T-cell lymphoma (VALENTINE-PTCL01): a multicentre, open-label, single-arm, phase 2 study.

Background: Peripheral T-cell lymphomas are aggressive non-Hodgkin lymphomas with few treatment options for relapsed or refractory disease. Valemetostat tosylate (valemetostat) is a potent, novel, dual inhibitor of EZH2 and EZH1. We investigated the clinical activity and safety of valemetostat in patients with relapsed or refractory peripheral T-cell lymphoma, and its safety in patients with relapsed or refractory adult T-cell leukaemia/lymphoma.

Evaluation of bleeding risk in patients who received pirtobrutinib in the presence or absence of antithrombotic therapy.

Clinical bleeding events are reported here from 773 patients with B-cell malignancies receiving pirtobrutinib monotherapy from the phase 1/2 BRUIN study (ClinicalTrials.gov identifier: NCT03740529), either in the presence or absence of antithrombotic therapy (antithrombotic exposed [AT-E],  = 216; antithrombotic nonexposed [AT-NE],  = 557). Among the AT-E cohort, 51.

Patient-reported outcomes in patients with relapsed or refractory follicular lymphoma treated with zanubrutinib plus obinutuzumab versus obinutuzumab monotherapy: results from the ROSEWOOD trial.

Objective: We report patient-reported outcomes (PROs) measuring health-related quality of life (HRQoL) from the ROSEWOOD trial (NCT03332017), which demonstrated superior efficacy and a manageable safety profile with zanubrutinib plus obinutuzumab (ZO) versus obinutuzumab (O) in patients with heavily pretreated relapsed/refractory follicular lymphoma (R/R FL).

Methods: PROs were assessed using the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire - Core 30 (EORTC QLQ-C30) and EQ-5D-5L questionnaires at baseline and subsequently every 12 weeks. All QLQ-C30 domains and EQ-5D-5L visual analog scale (VAS) scores were analyzed descriptively.

Efficacy and Safety of Frontline Single-Agent Rituximab in Extranodal Marginal Zone Lymphoma.

First-line therapy for patients with extranodal marginal zone lymphoma (EMZL) is not well established, except for eradication therapy for Helicobacter pylori in early gastric MZL. Various regimens, for example, locoregional treatment and systemic chemo-immunotherapy, can be used depending on the site and stage of disease. Single-agent rituximab is a useful approach in the setting of localized, low-intermediate risk EMZL.

The PI3Kδ inhibitor zandelisib on intermittent dosing in relapsed/refractory follicular lymphoma: Results from a global phase 2 study.

In this global phase 2 study in patients with relapsed/refractory follicular lymphoma (FL), zandelisib was administered on intermittent dosing to mitigate immune-related adverse events and infections that have been reported with oral PI3Kδ inhibitors administered daily continuously. Eligible patients with measurable disease and progression after at least two prior therapies were administered zandelisib until disease progression or intolerability. The primary efficacy endpoint was objective response rate (ORR) and the key secondary efficacy endpoint was duration of response (DOR).

Role of gut microbiome in the outcome of lymphoma patients treated with checkpoint inhibitors-The MicroLinf Study.

Biomarkers for immune checkpoint inhibitors (ICIs) response and resistance include PD-L1 expression and other environmental factors, among which the gut microbiome (GM) is gaining increasing interest especially in lymphomas. To explore the potential role of GM in this clinical issue, feces of 30 relapsed/refractory lymphoma (Hodgkin and primary mediastinal B-cell lymphoma) patients undergoing ICIs were collected from start to end of treatment (EoT). GM was profiled through Illumina, that is, 16S rRNA sequencing, and subsequently processed through a bioinformatics pipeline.

CHRONOS-4: phase 3 study of copanlisib plus rituximab-based immunochemotherapy in relapsed indolent B-cell lymphoma.

Copanlisib, a pan-class I phosphatidylinositol 3-kinase inhibitor with predominant activity against the α and δ isoforms, previously demonstrated durable responses as monotherapy and improved progression-free survival (PFS) in combination with rituximab in patients with relapsed indolent non-Hodgkin lymphoma (iNHL). CHRONOS-4 was a phase 3, randomized, double-blind, placebo-controlled study to investigate the efficacy and safety of copanlisib in combination with standard immunochemotherapy in patients with relapsed iNHL. Patients (n = 524) were randomized (1:1) to copanlisib (60 mg IV) plus immunochemotherapy (rituximab and bendamustine [R-B] or placebo plus R-B).

A Multicenter Real-life Prospective Study of Axicabtagene Ciloleucel versus Tisagenlecleucel Toxicity and Outcomes in Large B-cell Lymphomas.

This real-world prospective observational study across 21 Italian centers (CART-SIE) compares axicabtagene ciloleucel (axi-cel) and tisagenlecleucel (tisa-cel) outcomes in 485 patients with relapsed/refractory large B-cell lymphoma with baseline characteristics matched by stabilized inverse propensity score weighting. Axi-cel versus tisa-cel had higher all-grade cytokine release syndrome (78.6% vs.

CAR+ extracellular vesicles predict ICANS in patients with B cell lymphomas treated with CD19-directed CAR T cells.

BACKGROUNDPredicting immune effector cell-associated neurotoxicity syndrome (ICANS) in patients infused with CAR T cells is still a conundrum. This complication, thought to be consequent to CAR T cell activation, arises a few days after infusion, when circulating CAR T cells are scarce and specific CAR T cell-derived biomarkers are lacking.METHODSCAR+ extracellular vesicle (CAR+EV) release was assessed in human CD19.

Ibrutinib combined with immunochemotherapy with or without autologous stem-cell transplantation versus immunochemotherapy and autologous stem-cell transplantation in previously untreated patients with mantle cell lymphoma (TRIANGLE): a three-arm, randomised, open-label, phase 3 superiority trial of the European Mantle Cell Lymphoma Network.

Background: Adding ibrutinib to standard immunochemotherapy might improve outcomes and challenge autologous stem-cell transplantation (ASCT) in younger (aged 65 years or younger) mantle cell lymphoma patients. This trial aimed to investigate whether the addition of ibrutinib results in a superior clinical outcome compared with the pre-trial immunochemotherapy standard with ASCT or an ibrutinib-containing treatment without ASCT. We also investigated whether standard treatment with ASCT is superior to a treatment adding ibrutinib but without ASCT.
