Introduction: In the OPTIMISMM trial, pomalidomide/bortezomib/dexamethasone (PVd) significantly prolonged median progression-free survival (PFS) versus bortezomib/dexamethasone (Vd) in lenalidomide-exposed relapsed and refractory multiple myeloma (RRMM). We report final overall survival (OS) and updated efficacy analyses.
Methods: Adults with RRMM who had 1-3 prior regimens, including lenalidomide (≥ 2 cycles), were assigned (1:1) to PVd or Vd.
Introduction: Ixazomib, lenalidomide, and dexamethasone (IRd) have been approved for the treatment of relapsed/refractory multiple myeloma (RRMM) based on the results of the TOURMALINE-MM1.
Objectives And Methods: We conducted a retrospective-prospective analysis of 106 RRMM patients (pts) treated with IRd in 21 centers in Northern Italy, with the aim to evaluate the efficacy and safety of IRd in real life.
Results: At IRd initiation, 34% of pts were aged ≥75 (median 72.
Introduction: A proportion of patients with multiple myeloma (MM) are older and/or have comorbidities, requiring dose adjustments. Data from OPTIMISMM (NCT01734928) supported the use of pomalidomide, bortezomib, and dexamethasone (PVd) for treating relapsed/refractory MM. This subanalysis of OPTIMISMM assessed outcome by frailty and/or bortezomib dose adjustment.
View Article and Find Full Text PDFMultiple myeloma (MM) cells from 1 out of 20 patient expressed high basal levels of membrane B-cell maturation antigen (BCMA, TNFRSF17, CD269), which was not upregulated by gamma-secretase inhibitor, suggesting a defective BCMA shedding by gamma-secretase. Genetic analyses of the patient's bone marrow DNA showed no mutations within the BCMA coding region, but rather partial deletion of PSEN1 and amplification of PSEN2, which encode alternative catalytic units of gamma-secretase. Altogether the data suggest that pt#12 MM cells express high and dysregulated BCMA with no shedding, due to genetic alterations of one or more gamma-secretase subunits.

Methods: In this analysis, we aimed at confirming the role of CMR, and complementarity with BM multiparameter flow cytometry (MFC) at 10, in an independent cohort of newly diagnosed transplant-eligible MM patients previously enrolled in the phase II randomised FORTE trial. 109 of the 474 global patients enrolled in the trial between February 23, 2015, and April 5, 2017, who had paired PET/CT (performed at baseline [B] and preceding maintenance therapy [PM]) and MFC evaluation, were included in this analysis.
Lenalidomide and dexamethasone (Rd)-based triplets, in particular carfilzomib-Rd (KRd) and daratumumab-Rd (DaraRd), represent a standard of care in lenalidomide-sensitive multiple myeloma (MM) patients in first relapse. Meta-analysis of randomized clinical trials (RCT), suggested better outcome with DaraRd. Trying to address this issue in clinical practice, we collected data of 430 consecutive MM patients addressed to Rd-based triplets in first relapse between January 2017 and March 2021.

The present study aimed to develop two survival risk scores (RS) for overall survival (OS, SRS ) and progression-free survival (PFS, PRS ) in 919 relapsed/refractory multiple myeloma (RRMM) patients who received carfilzomib, lenalidomide, and dexamethasone (KRd)/elotuzumab, lenalidomide, and dexamethasone (EloRd). The median OS was 35.4 months, with no significant difference between the KRd arm versus the EloRd arm.

The present study is a 3-year follow-up update of a previously published Italian real-life RRMM cohort of patients treated with EloRd. This revised analysis entered 319 RRMM patients accrued in 41 Italian centers.

Five independent retrospective cohorts of 883 relapsed/refractory multiple myeloma (RRMM) patients, including 300 EloRd and 583 KRd cases, outside clinical trials, entered this non-randomized comparison. KRd cohort accounted for a higher incidence of younger patients, cases with ≥3 lines of therapy, already exposed to lenalidomide, International Staging System (ISS) stage III, and abnormal lactic dehydrogenase (LDH) level compared with EloRd cohort.

Methods: OPTIMISMM was a phase 3, multicenter, open-label, randomized study (NCT01734928; N = 559). The primary endpoint was progression-free survival (PFS).
Objectives: Autologous stem cell transplantation is the gold standard for eligible newly diagnosed multiple myeloma patients. Patients are usually hospitalized for administration of mobilization chemotherapy. We aimed to assess safety and efficacy of mobilization therapy with low-dose (2 g/m ) and intermediate-dose (3-4 g/m ) cyclophosphamide administered as outpatient.

In this randomized phase 3 study, we investigated efficacy and feasibility of dose/schedule-adjusted Rd followed by maintenance at 10 mg per day without dexamethasone (Rd-R) vs continuous Rd in elderly, intermediate-fit newly diagnosed patients with MM. Primary end point was event-free survival (EFS), defined as progression/death from any cause, lenalidomide discontinuation, or hematologic grade 4 or nonhematologic grade 3 to 4 adverse event (AE).

We report the results from the final analysis of the study.
Methods: In this randomised, open-label, phase 3 study, patients aged 18-65 years with previously untreated symptomatic multiple myeloma and a Karnofsky Performance Status of 60% or higher were enrolled at 73 centres in Italy.
Background: Selinexor combined with dexamethasone has shown activity in patients with heavily pre-treated multiple myeloma. In a phase 1b/2 study, the combination of oral selinexor with bortezomib (a proteasome inhibitor) and dexamethasone induced high response rates with low rates of peripheral neuropathy, the main dose-limiting toxicity of bortezomib. We aimed to evaluate the clinical benefit of weekly selinexor, bortezomib, and dexamethasone versus standard bortezomib and dexamethasone in patients with previously treated multiple myeloma.

However, despite their extensive use, head-to-head comparisons have never been performed. Therefore, we compared bortezomib and lenalidomide in fixed-duration therapies.

However, the kinetics of plerixafor-induced mobilization of lymphocyte subsets is poorly known. Here, we evaluated the graft content, the engraftment, and the immunological reconstitution of MM patients receiving plerixafor.
