Background: The refractory/relapsed multiple myeloma (RRMM) remains a big clinical challenge, due to its biological and clinical complexity. Leading hematologists have performed many randomized controlled trials (RCTs) worldwide, and their findings were summarized in a recently published network meta-analysis (NMA) but with certain limitations.
Materials And Methods: We performed an updated NMA of RCTs related to RRMM treatment, focusing on efficacy measures including the nonresponse rate (NRR), time to progression (TTP), progression-free survival (PFS), and overall survival (OS). The PubMed database was searched. We extended the literature search strategy of a previous NMA to June 30, 2017 and included additional primary RCTs. The surface under the cumulative ranking curve (SUCRA) was calculated to rank the regimens. A weighted-average method was used to rank the regimens by summarizing SUCRAs across different outcome measures.
Results: Finally, a total of 24 RCTs were included in this updated NMA. According to the result, the combination of daratumumab, lenalidomide, and dexamethasone showed better efficacy than other regimens in terms of NRR, TTP, and PFS (NRR: odds ratio [OR] =0.046, 95% credible interval [CrI] =[0.024, 0.085]; TTP: hazard ratio [HR] =0.14, 95% CrI =[0.092, 0.2]; PFS: HR =0.12, 95% CrI =[0.077, 0.18], compared with dexamethasone singlet). The combination of ixazomib, lenalidomide, and dexamethasone showed better efficacy than other regimens in terms of OS (HR =0.30, 95% CrI =[0.17, 0.54], compared with dexamethasone). The combination of daratumumab, lenalidomide, and dexamethasone ranked first in terms of overall efficacy (weighted average of SUCRAs =0.920).
Conclusion: The combination of daratumumab, lenalidomide, and dexamethasone may currently be the most effective regimen in the population of RRMM patients. Triplet regimens containing daratumumab, ixazomib, carfilzomib, or elotumumab plus lenalidomide and dexamethasone can be recommended as first-line therapies for RRMM patients.

Most transplant-ineligible patients present with multiple myeloma (MM) refractory to lenalidomide and/or anti-CD38 monoclonal antibody at first relapse and represent a difficult-to-treat population. The Intergroupe Francophone du Myélome phase 2 study iberdomide, ixazomib and dexamethasone (I2D) evaluated the oral triplet iberdomide, ixazomib and dexamethasone in MM patients aged ≥70 years at first relapse (NCT04998786). Seventy patients were enrolled to receive iberdomide (1.

Background: In CARTITUDE-4, ciltacabtagene autoleucel (cilta-cel) significantly improved progression-free survival (primary endpoint; previously reported) versus standard of care in patients with relapsed, lenalidomide-refractory multiple myeloma. We report here patient-reported outcomes.
Methods: In the ongoing, phase 3, open-label CARTITUDE-4 study, patients were recruited from 81 sites in the USA, Europe, Asia, and Australia, and were randomly assigned 1:1 to cilta-cel (target, 0·75 × 10 CAR-T cells/kg) or standard of care (daratumumab, pomalidomide, and dexamethasone; pomalidomide, bortezomib, and dexamethasone).

Early therapeutic intervention in high-risk smoldering multiple myeloma (HR-SMM) has shown benefits, however, no studies have assessed whether biochemical progression or response depth predicts long-term outcomes. The single-arm I-PRISM phase II trial (NCT02916771) evaluated ixazomib, lenalidomide, and dexamethasone in 55 patients with HR-SMM. The primary endpoint, median progression-free survival (PFS), was not reached (NR) (95% CI: 57.

Patients with multiple myeloma (MM) without high-risk cytogenetic abnormalities are classified as having standard-risk MM (SRMM), and data focusing on their outcomes after autologous hematopoietic stem cell transplantation (autoHCT) are limited. To evaluate survival outcomes for patients with SRMM receiving autoHCT, and to elucidate factors that impact these outcomes. Single-center retrospective analysis that included consecutive MM patients who received upfront autoHCT between 2013 and 2021, had available cytogenetic information and had no high-risk chromosomal abnormalities on fluorescence in situ hybridization, defined as t(4;14), t(14;16), del(17p) or 1q21 gain or amplification.
