Iberdomide, ixazomib and dexamethasone in elderly patients with multiple myeloma at first relapse.

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.

Real-Life Management of Patients Aged 80 Years Old and Over With Multiple Myeloma: Results of the EMMY Cohort.

Introduction: Multiple myeloma patients aged 80 years and older are a population more prone to comorbidities and frailty. We aim to describe the real-life management and outcomes of this population. EMMY is a descriptive large-scale study.

The EMMY longitudinal, cohort study: real-world data to describe multiple myeloma management and outcomes as more therapeutic options emerge.

The therapeutic management of patients with multiple myeloma (MM) is complex. Despite substantial advances, MM remains incurable, and management involves cycles of treatment response, disease relapse, and further therapy. Currently, evidence to support the therapeutic decision is limited.

Bortezomib, thalidomide, and dexamethasone with or without daratumumab and followed by daratumumab maintenance or observation in transplant-eligible newly diagnosed multiple myeloma: long-term follow-up of the CASSIOPEIA randomised controlled phase 3 trial.

Background: CASSIOPEIA part 1 demonstrated superior depth of response and prolonged progression-free survival with daratumumab in combination with bortezomib, thalidomide, and dexamethasone (D-VTd) versus bortezomib, thalidomide, and dexamethasone (VTd) alone as an induction and consolidation regimen in transplant-eligible patients newly diagnosed with myeloma. In CASSIOPEIA part 2, daratumumab maintenance significantly improved progression-free survival and increased minimal residual disease (MRD)-negativity rates versus observation. Here, we report long-term study outcomes of CASSIOPEIA.

The addition of bortezomib to rituximab, high-dose cytarabine and dexamethasone in relapsed or refractory mantle cell lymphoma-a randomized, open-label phase III trial of the European mantle cell lymphoma network.

The therapy of relapsed or refractory (r/r) mantle cell lymphoma (MCL) patients remains a major clinical challenge to date. We conducted a randomized, open-label, parallel-group phase-III trial hypothesizing superior efficacy of rituximab, high-dose cytarabine and dexamethasone with bortezomib (R-HAD + B) versus without (R-HAD) in r/r MCL ineligible for or relapsed after autologous stem cell transplant (ASCT). Primary endpoint was time to treatment failure (TTF), secondary endpoints included response rates, progression free survival, overall survival, and safety.

Impact of prior lenalidomide or proteasome inhibitor exposure on the effectiveness of ixazomib-lenalidomide-dexamethasone for relapsed/refractory multiple myeloma: A pooled analysis from the INSURE study.

Objectives: To characterize the impact of prior exposure and refractoriness to lenalidomide or proteasome inhibitors (PIs) on the effectiveness and safety of ixazomib-lenalidomide-dexamethasone (IRd) in relapsed/refractory multiple myeloma (RRMM).

Methods: INSURE is a pooled analysis of adult RRMM patients who had received IRd in ≥2 line of therapy from three studies: INSIGHT MM, UVEA-IXA, and REMIX.

Results: Overall, 391/100/68 were lenalidomide-naïve/-exposed/-refractory and 37/411/110 were PI-naïve/-exposed/-refractory.

RAS/RAF landscape in monoclonal plasma cell conditions.

Multiple myeloma is characterized by a huge heterogeneity at the molecular level. The RAS/RAF pathway is the most frequently mutated, in ∼50% of the patients. However, these mutations are frequently subclonal, suggesting a secondary event.

Daratumumab, carfilzomib, lenalidomide, and dexamethasone with tandem transplant for high-risk newly diagnosed myeloma.

High-risk (HR) cytogenetics are associated with poor outcomes in newly diagnosed multiple myeloma (NDMM), and dedicated studies should address this difficult-to-treat population. The phase 2 study 2018-04 from the Intergroupe Francophone du Myelome evaluated feasibility of an intensive strategy with quadruplet induction and consolidation plus tandem transplant in HR transplant-eligible (TE) NDMM. HR cytogenetics were defined by presence of del(17p), t(4;14), and/or t(14;16).

INSURE: a pooled analysis of ixazomib-lenalidomide-dexamethasone for relapsed/refractory myeloma in routine practice.

We pooled data from three observational studies (INSIGHT MM, UVEA-IXA and REMIX) to investigate the real-world effectiveness of ixazomib-lenalidomide-dexamethasone (IRd) in relapsed/refractory myeloma. INSIGHT MM was a prospective study conducted in countries across Europe, Asia and North/Latin America while UVEA-IXA and REMIX were multicenter, retrospective/prospective studies conducted in Europe. Patients who had received IRd as ≥2nd line of therapy were analyzed.

Venous thromboembolism prophylaxis and multiple myeloma patients in real-life: Results of a large survey and clinical guidance recommendations from the IFM group.

Venous thromboembolism (VTE) remains a critical issue in the management of patients with multiple myeloma (MM), particularly when immunomodulatory drugs (IMiDs) combined with dexamethasone therapy are being prescribed as first-line and relapse therapy. One possible explanation for the persistent high rates of VTE, is the use of inappropriate thromboprophylaxis strategies for patients starting antimyeloma treatment. To tackle the issue, the Intergroupe francophone du myélome (IFM) offered convenient guidance for VTE thromboprophylaxis in MM patients initiating systemic therapy.

Integrated analysis of randomized controlled trials evaluating bortezomib + lenalidomide + dexamethasone or bortezomib + thalidomide + dexamethasone induction in transplant-eligible newly diagnosed multiple myeloma.

Objective: Providing the most efficacious frontline treatment for newly diagnosed multiple myeloma (NDMM) is critical for patient outcomes. No direct comparisons have been made between bortezomib + lenalidomide + dexamethasone (VRD) and bortezomib + thalidomide + dexamethasone (VTD) induction regimens in transplant-eligible NDMM.

Methods: An integrated analysis was performed using patient data from four trials meeting prespecified eligibility criteria: two using VRD (PETHEMA GEM2012 and IFM 2009) and two using VTD (PETHEMA GEM2005 and IFM 2013-04).

Hairy cell leukaemia with unusual BRAF mutations.

Hairy cell leukaemia (HCL) diagnosis is based on the morphologic detection of circulating abnormal hairy cells in the peripheral blood and/or bone marrow, an HCL immunological score of 3 or 4 based on the expression of the CD11c, CD25, CD103 and CD123 and also the presence of a BRAF V600E activating mutation in the B-raf proto-oncogene (BRAF gene) (7q34). When using new generation sequencing of 21 targeted genes in 124 HCL patients, we identified a cohort of 6/124 (2%) patients with unusual BRAF mutations: two patients presented non-V600 mutations (BRAF F595L, BRAF W604L respectively) and four other patients silent BRAF mutations. When using droplet digital PCR (ddPCR) three of the four patients with concomitant BRAF V600E and silent mutation were negative.

Real-world effectiveness of ixazomib combined with lenalidomide and dexamethasone in relapsed/refractory multiple myeloma: the REMIX study.

Ixazomib (IXA) is an oral proteasome inhibitor (PI) used in combination with lenalidomide and dexamethasone (IXA-Rd) for patients with relapsed and/or refractory multiple myeloma (RRMM). The REMIX study is one of the largest prospective, real-world analysis of the effectiveness of IXA-Rd in the setting of RRMM. Conducted in France between August 2017 and October 2019, the REMIX study, a non-interventional prospective study, included 376 patients receiving IXA-Rd in second line or later and followed for at least 24 months.

Real-world study of the efficacy and safety of belantamab mafodotin (GSK2857916) in relapsed or refractory multiple myeloma based on data from the nominative ATU in France: the IFM 2020-04 study.

Belantamab mafodotin (BM) is an anti-BCMA antibody-drug conjugate (GSK2857916) that represents an alternative option in multiple myeloma. We sought to assess the efficacy and safety of BM in a real-world setting in patients who benefited from an early access program. We conducted an observational, retrospective, multicenter study.

Pomalidomide and dexamethasone until progression after first salvage therapy in multiple myeloma.

Lenalidomide maintenance in myeloma is well established. Nevertheless, pomalidomide could provide an alternative. Myeloma patients in first relapse, initially treated in the Intergroupe Francophone du Myélome (IFM) 2009 trial, and subsequently in the IFM 2013-01 phase 2 trial, received four cycles of salvage therapy with pomalidomide plus cyclophosphamide plus dexamethasone (PCD) with transplantation plus 2 PCD consolidation or without transplantation but with 5 PCD and for all patients pomalidomide plus dexamethasone maintenance therapy.

In Multiple Myeloma, High-Risk Secondary Genetic Events Observed at Relapse Are Present From Diagnosis in Tiny, Undetectable Subclonal Populations.

Purpose: Multiple myeloma (MM) is characterized by copy number abnormalities (CNAs), some of which influence patient outcomes and are sometimes observed only at relapse(s), suggesting their acquisition during tumor evolution. However, the presence of micro-subclones may be missed in bulk analyses. Here, we use single-cell genomics to determine how often these high-risk events are missed at diagnosis and selected at relapse.
