Real-World Treatment Patterns and Clinical Outcomes in Patients With Multiple Myeloma Previously Treated With Lenalidomide and an Anti-CD38 Monoclonal Antibody.

Background: This analysis explored real-world characteristics, treatment patterns and clinical outcomes in patients with relapsed or refractory multiple myeloma (RRMM) previously treated with lenalidomide and an anti-CD38 monoclonal antibody (mAb) and requiring subsequent treatment.

Materials And Methods: The PREAMBLE and Connect MM prospective registries of patients with multiple myeloma (MM), and the US nationwide Flatiron Health electronic health record-derived de-identified database were analysed. MM-specific treatment patterns (prior/index therapies) and outcomes (progression-free survival [PFS]/overall survival [OS]) were assessed.

Global disparities in drug-related adverse events of patients with multiple myeloma: a pharmacovigilance study.

Multiple myeloma (MM) is a complex hematological malignancy of clonal plasma cells driven by alterations to the chromosomal material leading to uncontrolled proliferation in the bone marrow. Ethnic and racial disparities persist in the prevalence, diagnosis, management, and outcomes of MM. These disparities are multifaceted and intersect with various factors, including demographics, geography, socioeconomic status, genetics, and access to healthcare.

Real-World Safety and Health Care Resource Utilization of Teclistamab Under an Outpatient Model for Step-Up Dosing Administration.

Purpose: Teclistamab is initiated with a step-up dosing (SUD) schedule to mitigate the risk of cytokine release syndrome (CRS) and immune effector cell-associated neurotoxicity syndrome (ICANS). Early teclistamab users commonly received SUD in a hospital setting. This study aimed to evaluate safety and health care resource utilization (HRU) in real-world patients with multiple myeloma who initiated teclistamab SUD in an outpatient setting.

Health care costs among patients with relapsed/refractory multiple myeloma treated with ixazomib or daratumumab in combination with lenalidomide and dexamethasone in the United States.

Background: Available treatments for relapsed/refractory multiple myeloma (RRMM) include multiclass triplet regimens such as lenalidomide and dexamethasone (Rd backbone) plus ixazomib (proteasome inhibitor [PI]; I) or daratumumab (monoclonal antibody; D). Although prior real-world studies compared PI-Rd triplets, this research extends those findings by comparing health care costs of a PI-based and a monoclonal antibody-based triplet, IRd and DRd, in patients with RRMM in the United States.

Objective: To describe and compare all-cause and MM-related health care costs in patients with RRMM treated with IRd vs DRd.

Characteristics and Treatment Patterns of Long-surviving Patients With Multiple Myeloma: Over 13 Years of Follow-up in the Connect MM Registry.

Background: Over the last 15 years, improvements in patient management and treatments have been associated with longer survival in patients with multiple myeloma (MM). The Connect MM Registry is a long-running, US, multicenter, prospective observational cohort study of patients with newly diagnosed MM (NDMM). We assessed the demographics, clinical characteristics, and treatment patterns of long-term survivors (LTS) enrolled in this registry.

Impact of lenalidomide-bortezomib-dexamethasone induction on patients with newly diagnosed multiple myeloma and renal impairment: Results from the Connect® MM Registry.

Limited data exist on the effects of induction treatment in patients with newly diagnosed multiple myeloma (NDMM) and renal impairment (RI), who may also be ineligible for autologous stem cell transplant. This analysis investigated the impact of lenalidomide-bortezomib-dexamethasone (RVd) induction on renal function in patients from the Connect® MM Registry based on transplant status. Eligible patients were aged ≥18 years with symptomatic MM diagnosed ≤2 months before enrollment.

Use of Hematopoietic Cell Transplant for Hematologic Cancers by Race, Ethnicity, and Age.

Importance: Utilization of hematopoietic cell transplantation (HCT) for hematologic cancers previously demonstrated race, ethnicity, and age-based disparities.

Objective: To evaluate utilization over time by race, ethnicity, and age to determine if disparities persist in light of recent significant increases in HCT volume.

Design, Setting, And Participants: This US population-based retrospective cohort study includes patients who received transplants from January 2009 to December 2018.

Ide-cel vs standard regimens in triple-class-exposed relapsed and refractory multiple myeloma: updated KarMMa-3 analyses.

Outcomes are poor in triple-class-exposed (TCE) relapsed and refractory multiple myeloma (R/RMM). In the phase 3 KarMMa-3 trial, patients with TCE R/RMM and 2 to 4 prior regimens were randomized 2:1 to idecabtagene vicleucel (ide-cel) or standard regimens (SRs). An interim analysis (IA) demonstrated significantly longer median progression-free survival (PFS; primary end point; 13.

The Effect of Age and Other Patient Characteristics on Outcomes Among Nontransplanted Patients Who Were Treated With First-Line Lenalidomide, Bortezomib, and Dexamethasone: Results From the Connect MM Registry.

Background: Lenalidomide (R), bortezomib (V), and dexamethasone (d) is a standard-of-care regimen in newly diagnosed multiple myeloma (NDMM); however, characteristics and outcomes for nontransplanted patients receiving frontline RVd are not well understood.

Patients: The Connect MM Registry is a large, US, multicenter, prospective observational cohort study of NDMM patients.

Methods: This analysis investigated characteristics and outcomes of patients who received RVd alone or followed by Rd or R (RVd ± Rd/R) who did not undergo frontline autologous stem cell transplantation.

Multiomics analysis of IgM monoclonal gammopathies reveals epigenetic influence on oncogenesis via DNA methylation.

Currently, the role of DNA methylation in the immunoglobulin M (IgM) monoclonal gammopathy disease spectrum remains poorly understood. In the present study, a multiomics prospective analysis was conducted integrating DNA methylation, RNA sequencing (RNA-seq), and whole-exome sequencing data in 34 subjects (23 with Waldenström macroglobulinemia [WM], 6 with IgM monoclonal gammopathy of undetermined significance [MGUS], and 5 normal controls). Analysis was focused on defining differences between IgM gammopathies (WM/IgM-MGUS) compared with controls, and specifically between WM and IgM-MGUS.

Factors determining utilization of stem cell transplant for initial therapy of multiple myeloma by patient race: exploring intra-racial healthcare disparities.

Multiple myeloma (MM) therapeutics have evolved tremendously in recent years, with significant improvement in patient outcomes. As newer treatment options are developed, stem cell transplant (SCT) remains an important modality that provides excellent disease control and delays the progression of disease. Over the years, SCT use has increased overall in the U.

Bispecific antibodies for the treatment of relapsed/refractory multiple myeloma: updates and future perspectives.

Patients with relapsed/refractory multiple myeloma (RRMM) that are refractory to the five most active anti-MM drugs, so-called penta-refractory MM, have historically had dismal outcomes with subsequent therapies. Progressive immune dysfunction, particularly of the T-cell repertoire, is implicated in the development of disease progression and refractory disease. However, the advent of novel immunotherapies such as bispecific antibodies are rapidly changing the treatment landscape and improving the survival outcomes of patients with RRMM.

Comparative effectiveness of lenalidomide/dexamethasone-based triplet regimens for treatment of relapsed and/or refractory multiple myeloma in the United States: An analysis of real-world electronic health records data.

Background: This retrospective longitudinal study compared the effectiveness of dexamethasone+lenalidomide (Rd)-based triplet regimens containing proteasome inhibitors (PIs) ixazomib (IRd), carfilzomib (KRd), and bortezomib (VRd) or monoclonal antibodies (MABs) elotuzumab (ERd) and daratumumab (DRd) in patients with relapsed/refractory multiple myeloma (RRMM)-including those with high cytogenetic risk-primarily treated at community oncology clinics in the United States.

Methods: Electronic health records of adult RRMM patients in a deidentified real-world database (01/01/2014-09/30/2020) who initiated IRd, KRd, VRd, ERd, or DRd in the second or later line of therapy (LOT) were analyzed. The index date was the date of initiation of each LOT and baseline was the 6-month pre-index period.

Management of Adverse Events Associated with Pomalidomide-Based Combinations in Patients with Relapsed/Refractory Multiple Myeloma.

Multi-agent regimens incorporating immunomodulatory (IMiD) agents such as thalidomide, lenalidomide, and pomalidomide have become the preferred standard of care for the treatment of patients with multiple myeloma (MM), resulting in improved survival outcomes. Currently, there are three IMiD agents approved for the treatment of MM: thalidomide, lenalidomide, and pomalidomide. Lenalidomide is commonly used to treat patients with newly diagnosed MM and as maintenance therapy following stem cell transplant or after disease relapse.

Health-related quality of life in patients with triple-class exposed relapsed and refractory multiple myeloma treated with idecabtagene vicleucel or standard regimens: patient-reported outcomes from the phase 3, randomised, open-label KarMMa-3 clinical trial.

Background: Chimeric antigen receptor T-cell therapy idecabtagene vicleucel (ide-cel) showed significantly improved progression-free survival compared with standard regimens in adults with relapsed and refractory multiple myeloma who had received two to four previous regimens in the ongoing phase 3 KarMMa-3 trial (NCT03651128). This study analysed patient-reported outcomes (PROs), a KarMMa-3 secondary endpoint.

Methods: In the randomised, open-label, phase 3 KarMMa-3 trial, 386 patients in hospitals (≥18 years of age, with measurable disease and an Eastern Cooperative Oncology Group performance status score of 0 or 1, who had received two to four previous regimens-including an immunomodulatory agent, a proteasome inhibitor, and daratumumab-and had documented disease progression after receiving their last dose of the last therapy) were randomly assigned to ide-cel (n=254) or standard regimens (daratumumab, pomalidomide, and dexamethasone; daratumumab, bortezomib, and dexamethasone; ixazomib, lenalidomide, and dexamethasone; carfilzomib and dexamethasone; or elotuzumab, pomalidomide, and dexamethasone; n=132).
