A Comparison of 3-Year Follow-up of ZUMA-5 (Axicabtagene Ciloleucel) With SCHOLAR-5 in Relapsed/Refractory Follicular Lymphoma.

In the pivotal ZUMA-5 trial, axicabtagene ciloleucel (axi-cel; an autologous anti-CD19 chimeric antigen receptor T-cell therapy) demonstrated high rates of durable response in relapsed/refractory follicular lymphoma patients. SCHOLAR-5 is an external control cohort designed to act as a comparator to ZUMA-5. Here, we present an updated comparative analysis of ZUMA-5 and SCHOLAR-5, using the 36-month follow-up data and the intent-to-treat population of ZUMA-5.

PET-based radiomics signature can predict durable responses to CAR T-cell therapy in patients with large B-cell lymphoma.

Chimeric antigen receptor (CAR) T-cell therapy is a promising treatment option for relapsed or refractory (R/R) large B-cell lymphoma (LBCL). However, only a subset of patients will present long-term benefit. In this study, we explored the potential of PET-based radiomics to predict treatment outcomes with the aim of improving patient selection for CAR T-cell therapy.

Controversies in central nervous system prophylaxis of high-risk diffuse large B-cell lymphoma.

Purpose Of Review: Central nervous system (CNS) relapse in patients with diffuse large B-cell lymphoma (DLBCL) is an uncommon but devastating complication with an overall survival of less than 6 months. This article will review the recent updates on CNS prophylaxis including new potential advances in the identification of high-risk patients.

Recent Findings: The identification of patients at a high risk of CNS relapse is based on clinical and biological features has improved over recent years; however, the of different CNS prophylaxis strategies including intrathecal chemotherapy and high-dose methotrexate have been recently questioned in several large retrospective studies.

Central nervous system lymphomas-Assessment and treatment and prevention of central nervous system relapse.

In this review focused on lymphoma and the central nervous system (CNS), we summarize recent developments in the management of primary (PCNSL) and secondary CNS lymphoma (SCNSL), treatment of CNS lymphoma in the older population, the neuroradiological assessment of CNS lymphoma and finally highlight the ongoing debate on optimal CNS prophylaxis. The section on PCNSL focuses on the different approaches available for frontline treatment in Europe and the United States and discusses consolidation strategies. We then highlight available strategies to treat PCNSL in the elderly population, an area of unmet need.

A 24-month updated analysis of the comparative effectiveness of ZUMA-5 (axi-cel) vs. SCHOLAR-5 external control in relapsed/refractory follicular lymphoma.

Background: In the ZUMA-5 trial (Clinical trials identification: NCT03105336), axicabtagene ciloleucel (axi-cel; a chimeric antigen receptor T-cell therapy) demonstrated high rates of durable response in relapsed/refractory (r/r) follicular lymphoma (FL) patients and clear superiority relative to the SCHOLAR-5 external control cohort. We update this comparison using the ZUMA-5 24-month data.

Research Design And Methods: The SCHOLAR-5 cohort is comprised of r/r FL patients who initiated ≥3 line of therapy after July 2014 and meeting ZUMA-5 eligibility criteria.

CNS prophylaxis in aggressive B-cell lymphoma.

The prevention of central nervous system (CNS) relapse in diffuse large B-cell lymphoma (DLBCL) continues to be one of the most contentious areas of lymphoma management. Outcomes for patients with secondary CNS lymphoma (SCNSL) have historically been very poor. However, in recent years improved responses have been reported with intensive immunochemotherapy approaches, and there is a growing interest in potential novel/cellular therapies.

Prevention and management of secondary central nervous system lymphoma.

Secondary central nervous system (CNS) lymphoma (SCNSL) is defined by the involvement of the CNS, either at the time of initial diagnosis of systemic lymphoma or in the setting of relapse, and can be either isolated or with synchronous systemic disease. The risk of CNS involvement in patients with diffuse large B-cell lymphoma is approximately 5%; however, certain clinical and biological features have been associated with a risk of up to 15%. There has been growing interest in improving the definition of patients at increased risk of CNS relapse, as well as identifying effective prophylactic strategies to prevent it.

Treatment patterns and outcomes in relapsed/refractory follicular lymphoma: results from the international SCHOLAR-5 study.

The SCHOLAR-5 study examines treatment patterns and outcomes of real-world follicular lymphoma (FL) patients on 3rd line of treatment (LoT) or higher, for whom existing data are limited. SCHOLAR-5 is a retrospective cohort study using data from adults (≥ 18 years) with grade 1-3a FL, initiating ≥3rd LoT after June 2014 at major lymphoma centers in the US and Europe. Objective response rate (ORR), complete response (CR), progression-free survival (PFS) and overall survival (OS) were analyzed by LoT.

Early progression in follicular lymphoma in the absence of histological transformation or high-risk Follicular Lymphoma International Prognostic Index still has a favourable outcome.

Although follicular lymphoma (FL) patients relapsing within 24 months after first-line treatment (POD24) have a poor prognosis, some cases show notable survival after first relapse (SF1R). We aimed to characterize the POD24 FL population and to identify the main prognostic factors at progression. We selected 162 POD24 patients (80F; median age at first relapse 59 years) from a cohort of 1067 grades 1-3a FL-treated patients.

Real-world data with the use of caplacizumab in the treatment of acquired thrombotic thrombocytopenic purpura: A single-center with homogeneous treatment experience.

Background: Recently, real-world data confirmed the effectiveness of caplacizumab in the treatment of acquired thrombotic thrombocytopenic purpura (aTTP); however, limitations as different treatment protocols from multicenter experiences and the front-line use of rituximab could overshadow the real impact of the addition of caplacizumab.

Study Design And Methods: We report the clinical characteristics and response to treatment of 30 consecutive cases of aTTP treated under a homogeneous therapeutic protocol with the only exception of the addition of caplacizumab in the last 10 cases (caplacizumab group), whose primary outcome we compare with the previous 20 cases (control group).

Results: Caplacizumab was started at a median of 2.

CNS prophylaxis for diffuse large B-cell lymphoma.

CNS relapse in the brain parenchyma, eyes, or leptomeninges is an uncommon but devastating complication of diffuse large B-cell lymphoma. CNS prophylaxis strategies, typically involving intrathecal or high-dose antimetabolites, have been developed in the front-line treatment setting with the aim to reduce this subsequent risk. Clinical and biological features associated with elevated risk are increasingly well defined and are discussed in this Review.

A gene expression assay based on chronic lymphocytic leukemia activation in the microenvironment to predict progression.

Several gene expression profiles with a strong correlation with patient outcomes have been previously described in chronic lymphocytic leukemia (CLL), although their applicability as biomarkers in clinical practice has been particularly limited. Here we describe the training and validation of a gene expression signature for predicting early progression in patients with CLL based on the analysis of 200 genes related to microenvironment signaling on the NanoString platform. In the training cohort (n = 154), the CLL15 assay containing a 15-gene signature was associated with the time to first treatment (TtFT) (hazard ratio [HR], 2.

Comparative effectiveness of ZUMA-5 (axi-cel) vs SCHOLAR-5 external control in relapsed/refractory follicular lymphoma.

In the pivotal ZUMA-5 trial, axicabtagene ciloleucel (axi-cel; an autologous anti-CD19 chimeric antigen receptor T-cell therapy) demonstrated high rates of durable response in relapsed/refractory (r/r) follicular lymphoma (FL) patients. Here, outcomes from ZUMA-5 are compared with the international SCHOLAR-5 cohort, which applied key ZUMA-5 trial eligibility criteria simulating randomized controlled trial conditions. SCHOLAR-5 data were extracted from institutions in 5 countries, and from 1 historical clinical trial, for r/r FL patients who initiated a third or higher line of therapy after July 2014.

Autologous stem-cell transplantation as consolidation of first-line chemotherapy in patients with peripheral T-cell lymphoma: a multicenter GELTAMO/FIL study.

Peripheral T-cell lymphomas (PTCL) are a heterogeneous group of rare lymphoid malignancies that mostly have poor prognoses with currently available treatments. Upfront consolidation with autologous stem cell transplantation (ASCT) is frequently carried out, but its efficacy has never been investigated in randomized trials. We designed a multicenter, international, retrospective study with the main objective of comparing progression-free survival and overall survival of patients with PTCL who underwent ASCT in complete remission (CR) after first-line chemotherapy with a control group who did not undergo ASCT.

Mortality in acquired thrombotic thrombocytopenic purpura in the pre-caplacizumab era.

Despite the effectiveness of plasma exchange (PEX) and immunosuppressants in the treatment of acquired thrombotic thrombocytopenic purpura (aTTP), a number of patients still die as a result of the disease. Whether caplacizumab could rescue these patients remains still unsettled. The objective of this study was to characterise mortality patterns and prognostic factors in the first episode of aTTP.

Prognostic impact of total metabolic tumor volume in large B-cell lymphoma patients receiving CAR T-cell therapy.

Chimeric antigen receptor (CAR) T-cell therapy provides long-term remissions in patients with relapsed or refractory (R/R) large B-cell lymphoma (LBCL). Total metabolic tumor volume (TMTV) assessed by 18F-fluorodeoxyglucose positron emission tomography (18FDG-PET) has a confirmed prognostic value in the setting of chemoimmunotherapy, but its predictive role with CAR T-cell therapy is not fully established. Thirty-five patients with R/R LBCL who received CAR T-cells were included in the study.

Prophylaxis with intrathecal or high-dose methotrexate in diffuse large B-cell lymphoma and high risk of CNS relapse.

Although methotrexate (MTX) is the most widely used therapy for central nervous system (CNS) prophylaxis in patients with diffuse large B-cell lymphoma (DLBCL), the optimal regimen remains unclear. We examined the efficacy of different prophylactic regimens in 585 patients with newly diagnosed DLBCL and high-risk for CNS relapse, treated with rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) or R-CHOP-like regimens from 2001 to 2017, of whom 295 (50%) received prophylaxis. Intrathecal (IT) MTX was given to 253 (86%) and high-dose MTX (HD-MTX) to 42 (14%).

Immunological and genetic kinetics from diagnosis to clinical progression in chronic lymphocytic leukemia.

Background: Mechanisms driving the progression of chronic lymphocytic leukemia (CLL) from its early stages are not fully understood. The acquisition of molecular changes at the time of progression has been observed in a small fraction of patients, suggesting that CLL progression is not mainly driven by dynamic clonal evolution. In order to shed light on mechanisms that lead to CLL progression, we investigated longitudinal changes in both the genetic and immunological scenarios.

Use of checkpoint inhibitors in patients with lymphoid malignancies receiving allogeneic cell transplantation: a review.

Monoclonal antibodies against checkpoint receptors or its ligands have demonstrated high response rates and durable remissions in patients with relapsed Hodgkin lymphoma (HL) and other lymphoid malignancies. However, most patients will eventually progress on therapy and may benefit from further treatments including allogenic hematopoietic cell transplantation (allo-HCT). Furthermore, the use of checkpoint inhibitors (CPI) has emerged as a treatment option for patients relapsing after allo-HCT.
