Ciltacabtagene autoleucel (cilta-cel) and idecabtagene vicleucel (ide-cel), two BCMA-directed chimeric antigen receptor T cell (CAR-T) therapies, have transformed outcomes for relapsed/refractory multiple myeloma (RRMM); however, the 6-8 weeks manufacturing time risks disease progression or death in up to 10% of patients, highlighting the need for effective bridging strategies. Talquetamab, a GPRC5D-targeting bispecific antibody, represents a promising option. We performed a multi-institutional retrospective analysis across 20 centers (18 US, 2 Germany) evaluating talquetamab as a bridging therapy prior to cilta-cel or ide-cel.

Idecabtagene vicleucel (ide-cel) was the first US Food and Drug Administration-approved chimeric antigen receptor T-cell (CAR-T) therapy for multiple myeloma (MM). However, because clinical trials are highly selective with stringent eligibility criteria, the objective of this study was to evaluate the safety and effectiveness of standard-of-care (SOC) ide-cel in the real world. Using the Center for International Blood and Marrow Transplant Research registry, we evaluated 821 patients who received SOC ide-cel.

Data regarding racial disparities in the incidence, treatment, and outcomes of diffuse large B-cell lymphoma (DLBCL) is limited in the adolescent and young adult (AYA) population. We utilized the surveillance, epidemiology, and end-result (SEER) registry research plus database to evaluate racial/ethnic disparities in 8605 AYA patients with DLBCL. Race/ethnicity was categorized into three main subsets: non-Hispanic Whites (NHW), non-Hispanic Blacks (NHB), and 'other races' that included Hispanics (H), American Indian/Alaskan Native (AI/AN), Asian or Pacific Islander (A/PI).

In patients with multiple myeloma (MM) not-eligible for autologous haematopoietic cell transplantation (autoHCT), a simplified frailty index (SFI) identifies frail patients at risk for poor outcomes, but data are limited for transplant-eligible patients. In this registry-based retrospective study, we used an adapted version of the SFI to determine the prevalence of frailty in patients ≥65 years of age with MM undergoing autoHCT. Out of 5563 patients, 37.

In this study, we compare outcomes of older patients with primary diffuse large B-cell lymphoma of the central nervous system (PCNSL) undergoing autologous hematopoietic cell transplantation (autoHCT) with either thiotepa/carmustine (BCNU/Thio) or thiotepa/busulfan/cyclophosphamide (TBC) conditioning. We used a postpublication dataset made available by the Center for International Blood and Marrow Transplantation Research including patients who were ≥65 years in age with PCNSL and underwent autoHCT as consolidation with TBC or BCNU/Thio conditioning. Out of 147 patients; n = 84 received BCNU/Thio and n = 63 received TBC.

Article Synopsis
  • The Glasgow prognostic score (GPS) and CAR-HEMATOTOX (CAR-HT) score help identify multiple myeloma (MM) patients at risk for immune-related side effects and early death during cellular immunotherapy.
  • A study involving 126 MM patients treated with T-cell redirecting bispecific antibodies (bsAb) assessed the impact of these scores on patient outcomes.
  • While 19% of patients were deemed high risk according to GPS, they did not experience worse outcomes, but those classified as high risk by CAR-HT faced more infections and had lower survival rates, indicating the need for better infection management.

Recent studies demonstrating the feasibility of outpatient chimeric antigen receptor (CAR)-modified T-cell therapy administration are either restricted to CARs with 41BB costimulatory domains or use intensive at-home monitoring. We report outcomes of outpatient administration of all commercially available CD19- and B-cell maturation antigen (BCMA)-directed CAR T-cell therapy using a strategy of no remote at-home monitoring and an early cytokine release syndrome (CRS) intervention strategy. Patients with hematologic malignancies who received CAR T-cell therapy in the outpatient setting during 2022 to 2023 were included.

Multiple chimeric antigen receptor (CAR) T-cell and bispecific antibody (bsAb) therapies have been approved, demonstrating impressive clinical efficacy in relapsed/refractory multiple myeloma (MM). Currently, these treatment share overlapping approval indications in the relapsed/refractory space, highlighting the importance of optimal selection and sequencing to maximize clinical efficacy. For patients previously unexposed to T-cell-directed therapies, several factors should be weighed when both options are available.

Administration of chimeric-antigen receptor T-cell (CAR-T) therapy is complex and associated with unique toxicities. Identifying patients at risk for inferior outcomes is important for individualized management. The Glasgow-prognostic score (GPS) is a simple score shown to be highly prognostic of outcomes in the setting of traditional chemotherapy or checkpoint inhibitor administration.

Introduction: Anti-B-cell maturation antigen (BCMA) chimeric antigen receptor T-cell (CAR-T) therapy is transforming the care of patients with relapsed/refractory multiple myeloma (MM). Unfortunately, despite being a disease of older adults these patients remain under-represented in most pivotal clinical trials. We performed a systematic review and proportion meta-analysis of prospective clinical trials and observational studies of anti-BCMA CAR-T therapy in patients with MM with the aim to determine the efficacy and safety of this therapy in older adults (≥65 years).

  • Researchers studied how well a medicine called venetoclax works for patients with a type of cancer called mantle cell lymphoma (MCL), looking at 81 patients in total.
  • About 40% of the patients showed improvement after taking venetoclax, but they only stayed healthy for an average of 3.7 months before the cancer returned, with some living up to 12.5 months overall.
  • Patients who had fewer than 4 previous treatments had better responses, but some faced risks like tumor lysis syndrome (TLS), which can cause serious problems despite safety measures.
