Commonly used first-line (1L) treatments for mantle cell lymphoma include high-dose cytarabine-based induction followed by autologous stem-cell transplant (ASCT) younger patients and several chemoimmunotherapy regimens older patients. Continuous debates exist on the role of ASCT in maintenance rituximab (MR) after bendamustine plus (BR).Retrospective data from 4,216 with Flatiron Health electronic record-derived deidentified database diagnosed between 2011 2021, mostly US community oncology...

In GLOW, fixed-duration ibrutinib + venetoclax showed superior progression-free survival (PFS) versus chlorambucil obinutuzumab in older/comorbid patients with previously untreated chronic lymphocytic leukemia (CLL). The current analysis describes minimal residual disease (MRD) kinetics and any potential predictive value for PFS, as it has not yet been evaluated treatment.

Abstract Background Patients with relapsed/refractory multiple myeloma are at increased risk of infection. Infections during treatment teclistamab, the first B‐cell maturation antigen‐directed bispecific antibody approved for triple‐class–exposed myeloma, was examined in phase 1/2 MajesTEC‐1 study. Methods ( N = 165) received subcutaneous teclistamab 1.5 mg/kg weekly after a step‐up dosing schedule (0.06 and 0.3 mg/kg, each separated by 2–4 days). were monitored frequently infections;...

Summary This United States community study evaluated the combination of daratumumab, bortezomib, cyclophosphamide and dexamethasone (D‐VCd) in newly diagnosed multiple myeloma (NDMM) relapsed (RMM). Patients received 4–8 induction cycles bortezomib 1·5 mg/m 2 , 300 40 mg weekly. Intravenous daratumumab 16 mg/kg was administered as approved except for a split‐first dose Cycle 1. Eligible patients underwent autologous stem cell transplantation. All ≤12 maintenance doses monthly. Eighty‐six...

The long-term outcome for patients with mantle cell lymphoma (MCL) has been improving; however, historical evidence indicates that progression-free survival (PFS) declines and high-risk factors accumulate each successive line of chemoimmunotherapy (CIT).1,2 Median PFS CIT declined by 70% from first-line (1L) (47.4 mo) to second-line (14.0 86% after third-line therapy (6.5 mo),1 emphasizing a need therapies will reverse or mitigate these trends. Ibrutinib is once-daily, oral inhibitor...

8034 Background: Teclistamab is the first B-cell maturation antigen (BCMA) bispecific antibody approved for treatment of relapsed/refractory multiple myeloma (RRMM) at a dose 1.5 mg/kg weekly (QW) given subcutaneously. A less frequent dosing schedule offers added convenience and flexibility to patients, physicians, caregivers. We evaluated ability patients maintain their responses after transitioning from QW every other week (Q2W) schedules in pivotal phase 1/2 MajesTEC-1 trial...

7517 Background: Emerging data suggest that administering toci prior to bispecific antibodies reduces the incidence of CRS, which may support outpatient therapy initiation. We previously showed CRS with teclistamab, first approved BCMA×CD3 antibody weight-based dosing for treatment pts triple-class exposed RRMM, was reduced from 72% in overall MajesTEC-1 study population 26% a cohort receiving single dose before teclistamab step-up dose. Here, we present an updated analysis longer-term...

Abstract Introduction Ciltacabtagene autoleucel (cilta‐cel) is a novel chimeric antigen receptor T‐cell therapy that being evaluated in the CARTITUDE‐1 trial (NCT03548207) patients with relapsed or refractory multiple myeloma (RRMM) who received as part of their previous an immunomodulatory drug, proteasome inhibitor, and anti‐CD38 monoclonal antibody (i.e., triple‐class exposed). Given absence control arm CARTITUDE‐1, this study assessed comparative effectiveness cilta‐cel physician's...

In the primary analysis of LYRA, daratumumab + cyclophosphamide/bortezomib/dexamethasone (DARA CyBorD) was effective and well tolerated in newly diagnosed multiple myeloma (NDMM) relapsed (RMM). We report final LYRA (median months follow-up: NDMM, 35.7; RMM, 35.3) after all patients completed study therapy, were followed for 36 months, or discontinued. Patients received DARA CyBorD induction, autologous stem cell transplant (if eligible), 12 maintenance. Eighty-seven NDMM enrolled, 39...

Ciltacabtagene autoleucel (cilta-cel) is a novel agent being investigated in the single-arm CARTITUDE-1 trial (NCT03548207) for patients with relapsed or refractory multiple myeloma who are triple-class exposed to an immunomodulatory drug, proteasome inhibitor, and anti-CD38 monoclonal antibody. The objective of this study was evaluate comparative efficacy cilta-cel vs physician's choice treatment, as no head-to-head trials have been conducted. An external control arm created from long-term...

Aim: We compared the effectiveness of teclistamab versus real-world physician's choice therapy (RWPC) in triple-class exposed relapsed/refractory multiple myeloma. Materials & methods: MajesTEC-1 eligibility criteria were applied to RWPC cohort. Baseline covariate imbalances adjusted using inverse probability treatment weighting. Overall survival, progression-free survival and time next compared. Results: After weighting, baseline characteristics similar between cohorts (teclistamab, n =...
