Isatuximab, carfilzomib, lenalidomide, and dexamethasone induction in newly diagnosed myeloma: analysis of the MIDAS trial.

For patients with transplant-eligible newly diagnosed multiple myeloma, induction therapy with a quadruplet regimen before autologous transplant is the standard of care. The phase 3 IFM2020-02-MRD-adapted strategy (MIDAS) study assessed a minimal residual disease (MRD)-driven consolidation and maintenance strategy after induction with isatuximab, carfilzomib, lenalidomide, and dexamethasone (IsaKRD). We report safety and efficacy outcomes of six 28-day cycles of IsaKRD in 791 patients.

Ibrutinib as a treatment of hematologic autoimmune disorders in patients with indolent B-cell lymphoma.

Background: Autoimmune conditions in B-cell lymphomas are frequent. Steroids are standard of care, but many patients require other immunosuppressive agents. Ibrutinib is a Bruton Tyrosine Kinase inhibitor that is approved for B-cell indolent lymphoma treatment.

Oral ixazomib-dexamethasone vs oral pomalidomide-dexamethasone for lenalidomide-refractory, proteasome inhibitor-exposed multiple myeloma: a randomized Phase 2 trial.

Multiple myeloma (MM) patients typically receive several lines of combination therapy and first-line treatment commonly includes lenalidomide. As patients age, they become less tolerant to treatment, requiring convenient/tolerable/lenalidomide-free options. Carfilzomib and/or bortezomib-exposed/intolerant, lenalidomide-refractory MM patients with ≥2 prior lines of therapy were randomized 3:2 to ixazomib-dexamethasone (ixa-dex) (n = 73) or pomalidomide-dexamethasone (pom-dex) (n = 49) until progression/toxicity.

Daratumumab and dexamethasone is safe and effective for triple refractory myeloma patients: final results of the IFM 2014-04 (Etoile du Nord) trial.

Single agent daratumumab has shown clinical activity in relapsed, refractory multiple myeloma (RRMM). The Intergroupe Francophone du Myélome 2014-04 trial was designed to further investigate daratumumab in combination with dexamethasone in triple RRMM patients. Patients received daratumumab infusions in combination with weekly dexamethasone until disease progression or unacceptable toxicity.

Response to pneumococcal vaccination in multiple myeloma.

Background: Streptococcus pneumoniae infection causes morbidity and mortality in multiple myeloma patients. Pneumococcal vaccination is commonly given to immunocompromised myeloma patients; however response data are sparse. Here, we present longitudinal response data to pneumococcal vaccination in multiple myeloma patients.

Development and Validation of a Cytogenetic Prognostic Index Predicting Survival in Multiple Myeloma.

Purpose: The wide heterogeneity in multiple myeloma (MM) outcome is driven mainly by cytogenetic abnormalities. The current definition of high-risk profile is restrictive and oversimplified. To adapt MM treatment to risk, we need to better define a cytogenetic risk classification.

Efficacy and tolerability of nivolumab after allogeneic transplantation for relapsed Hodgkin lymphoma.

Allogeneic hematopoietic cell transplantation (allo-HCT) is indicated for patients with relapsed or refractory Hodgkin lymphoma (HL). Although long-term disease control can be achieved, relapse is still frequent. The programmed cell death protein 1 (PD-1) pathway-blocking antibody nivolumab has shown substantial therapeutic activity and an acceptable safety profile in patients with relapsed or refractory HL who did not receive allo-HCT.

IgMκ and IgMλ Measurements for the Assessment of Patients with Waldenström's Macroglobulinaemia.

Purpose: Accurate quantification of monoclonal IgM immunoglobulins is essential for response assessment in patients with Waldenström's macroglobulinaemia (WM). The propensity of IgM to form multimers in serum makes sample evaluation by current laboratory methods particularly challenging.

Experimental Design: We assessed the precision and linearity of IgMκ and IgMλ heavy/light chain (HLC, Hevylite) assays, and established reference intervals using 120 normal donor sera.

Lenalidomide is safe and active in Waldenström macroglobulinemia.

Lenalidomide is manageable and effective in multiple myeloma, particularly in elderly patients. Surprisingly, the combination of lenalidomide with rituximab produced clinically significant anemia at 25 mg/day for 21/28 days, the highest possible dose, in Waldenström's Macroglobulinemia (WM). We aimed to determine the maximum tolerated dose (MTD) of single agent lenalidomide and determine its impact on WM.

MYD88 L265P mutation contributes to the diagnosis of Bing Neel syndrome.

Bing-Neel syndrome (BNS), a rare neurological syndrome associated with Waldenström macroglobulinaemia (WM), is a direct involvement of the central nervous system by lymphoplasmacytoid cells characterized with an adverse prognostic. The MYD88 L265P mutation has been identified in the vast majority of patients with WM. The diagnosis of BNS is often challenging because of the variety of clinical presentations associated with difficult histological techniques.

IgA kappa/IgA lambda heavy/light chain assessment in the management of patients with IgA myeloma.

Background: Accurate quantification of immunoglobulin A (IgA) monoclonal immunoglobulins by serum protein electrophoresis (SPEP) can be difficult and can impact the assessment of response among patients with multiple myeloma (MM). Therefore, there is a need to identify new assays that better reflect disease burden and response to treatment, and correlate with patient outcome. IgA Hevylite (HLC) measures IgA kappa and IgA lambda separately and provides precise quantitative measurements of the monoclonal IgA expression and polyclonal-isotype matched suppression.

Impact of initial FDG-PET/CT and serum-free light chain on transformation of conventionally defined solitary plasmacytoma to multiple myeloma.

Purpose: Solitary plasmacytoma (SP) is a localized proliferation of monoclonal plasma cells in either bone or soft tissue, without evidence of multiple myeloma (MM), and whose prognosis is marked by a high risk of transformation to MM.

Experimental Design: We studied the impact of FDG-PET/CT (2[18F]fluoro-2-deoxy-D-glucose positron emission tomography-computed tomography) on the risk of transformation of SP to overt MM among other markers in a series of 43 patients diagnosed with SP.

Results: Median age was 57.

Efficacy and safety profile of long-term exposure to lenalidomide in patients with recurrent multiple myeloma.

Background: Lenalidomide in combination with dexamethasone (Len/Dex) is indicated for patients with recurrent/refractory multiple myeloma (RRMM) who were treated with 1 prior therapy until evidence of disease progression. The objective of the current study was to determine the efficacy and safety profile of long-term exposure to Len/Dex.

Methods: A total of 50 patients with RRMM who were treated with long-term Len for ≥ 2 years from 2 Intergroupe Francophone du Myélome (IFM) centers (Lille and Nancy) were included in the current study.

[Brentuximab vedotin: new treatment for CD30+ lymphomas].

Brentuximab vedotin is a new antibody-drug conjugate composed of the anti-CD30 chimeric monoclonal antibody and the potent antimicrotubule drug monomethylauristatin E. In two phase II clinical trials, treatment with single-agent brentuximab vedotin resulted in response rates of 75% in relapsed/refractory Hodgkin lymphoma and 86% in relapsed/refractory systemic anaplastic large-cell lymphoma. Peripheral sensory neuropathy (40%) and neutropenia (20%) were the most frequent side effects, generally mild and manageable.
