Background: The introduction of proteasome inhibitors (PIs) and lenalidomide as treatment for newly diagnosed multiple myeloma (MM) has led to an increased population of lenalidomide-refractory patients. Limited data are available characterizing current treatments and outcomes in this difficult-to-treat population.

Methods: Individual patient-level data were analyzed from the treatment arms of multiple daratumumab studies, including APOLLO, CASTOR, CANDOR, EQUULEUS, ALCYONE, MAIA, GRIFFIN, POLLUX, and CASSIOPEIA.

Article Synopsis
  • - Talquetamab is effective for treating patients with relapsed/refractory multiple myeloma who have already undergone multiple treatments, as evaluated in the MonumenTAL-1 study compared to real-world treatments.
  • - The study utilized external control data from the Flatiron Health database, including over 600 eligible patients, and analyzed outcomes for two dosage schedules of talquetamab (0.4 mg/kg weekly and 0.8 mg/kg biweekly).
  • - Results indicated that both talquetamab dosages significantly improved progression-free survival, time to next treatment, and overall survival compared to standard real-world options, supporting its use as an effective immunotherapy.

Background: Patients with relapsed/refractory multiple myeloma are at increased risk of infection. Infections during treatment with teclistamab, the first B-cell maturation antigen-directed bispecific antibody approved for triple-class-exposed relapsed/refractory multiple myeloma, was examined in the phase 1/2 MajesTEC-1 study.

Methods: Patients (N = 165) received subcutaneous teclistamab 1.

Background: In the GLOW study, fixed-duration ibrutinib-venetoclax showed superior progression-free survival versus chlorambucil-obinutuzumab in patients with previously untreated chronic lymphocytic leukaemia who were older or had comorbidities, or both, at a median follow up of 27·7 months. In this Article, we report updated outcomes from GLOW after a 46-month median follow-up.

Methods: GLOW was a randomised, multicentre, phase 3 study done at 67 hospital centres across 14 countries.

Purpose: 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 for ibrutinib + venetoclax treatment.

Methods: Undetectable MRD (uMRD) was assessed by next-generation sequencing at <1 CLL cell per 10,000 (<10) and <1 CLL cell per 100,000 (<10) leukocytes.

We compared the effectiveness of teclistamab versus real-world physician's choice of therapy (RWPC) in triple-class exposed relapsed/refractory multiple myeloma. MajesTEC-1 eligibility criteria were applied to the RWPC cohort. Baseline covariate imbalances were adjusted using inverse probability of treatment weighting.

Article Synopsis
  • - Erdafitinib is used to treat adults with advanced urothelial carcinoma who have not responded to prior platinum-based chemotherapy, aiming to understand the frequency and management of side effects from this treatment.
  • - In the BLC2001 clinical trial, 101 patients were treated with a specific dosage and monitoring for side effects like hyperphosphatemia, stomatitis, and skin issues, with most side effects being mild (grade 1 or 2) and manageable.
  • - Results showed that while some adverse events did occur, they were typically manageable, leading to few patients needing to stop treatment, but more research is necessary to see if these management strategies apply to a broader patient population.

Background: The efficacy and safety of teclistamab in patients with RRMM who received ≥3 prior lines of therapy and were triple-class exposed (TCE) are being evaluated in the single-arm, multicohort, phase I/II MajesTEC-1 trial (NCT04557098). We evaluated the comparative effectiveness of teclistamab versus physician's choice (PC) of therapy in TCE RRMM patients.

Methods: Individual patient-level data from MajesTEC-1 patients who received teclistamab (1.

Introduction: Ciltacabtagene autoleucel (cilta-cel) is a novel chimeric antigen receptor T-cell therapy that is being evaluated in the CARTITUDE-1 trial (NCT03548207) in patients with relapsed or refractory multiple myeloma (RRMM) who received as part of their previous therapy an immunomodulatory drug, proteasome inhibitor, and an anti-CD38 monoclonal antibody (i.e., triple-class exposed).

Purpose: Commonly used first-line (1L) treatments for mantle cell lymphoma include high-dose cytarabine-based induction followed by autologous stem-cell transplant (ASCT) for younger patients and several chemoimmunotherapy regimens for older patients. Continuous debates exist on the role of ASCT in younger patients and maintenance rituximab (MR) after bendamustine plus rituximab (BR).

Methods: Retrospective data from 4,216 patients with mantle cell lymphoma in the Flatiron Health electronic record-derived deidentified database diagnosed between 2011 and 2021, mostly in US community oncology settings, were evaluated for treatment patterns and outcomes.

In the primary analysis of LYRA, daratumumab + cyclophosphamide/bortezomib/dexamethasone (DARA + CyBorD) was effective and well tolerated in newly diagnosed multiple myeloma (NDMM) and relapsed multiple myeloma (RMM). We report the final analysis of LYRA (median months of follow-up: NDMM, 35.7; RMM, 35.

Background And Objective: 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 an anti-CD38 monoclonal antibody. The objective of this study was to evaluate the comparative efficacy of cilta-cel vs physician's choice of treatment, as no head-to-head trials have been conducted.

Methods: An external control arm for CARTITUDE-1 was created from patients in the long-term follow-up for three clinical trials of daratumumab (POLLUX, CASTOR, and EQUULEUS) who satisfied the eligibility criteria of CARTITUDE-1.

Objectives: Unequivocal clinical progression (UCP)-a worsening of clinical status with or without radiographic progression (RAD)-represents a distinct mode of disease progression in metastatic prostate cancer. We evaluated the prevalence, risk factors and the impact of UCP on survival outcomes.

Methods: A post-hoc analysis of the COU-AA-302, a randomised phase 3 study of abiraterone plus prednisone (AAP) versus prednisone was performed.

This United States community study evaluated the combination of daratumumab, bortezomib, cyclophosphamide and dexamethasone (D-VCd) in newly diagnosed multiple myeloma (NDMM) and relapsed multiple myeloma (RMM). Patients received 4-8 induction cycles of bortezomib 1·5 mg/m , cyclophosphamide 300 mg/m and dexamethasone 40 mg weekly. Intravenous daratumumab 16 mg/kg was administered as approved except for a split-first dose in Cycle 1.

Objective: To evaluate the safety and efficacy of abatacept plus methotrexate (MTX) over 5 years in patients with rheumatoid arthritis.

Methods: Patients were randomized to abatacept 10 or 2 mg/kg or placebo, plus MTX. Patients completing the 1-year, double-blind period entered the longterm extension, where all patients received a fixed dose of abatacept ~10 mg/kg.
