Prognostic Value of Galectin-9 Relates to Programmed Death-Ligand 1 in Patients With Multiple Myeloma.

Galectin-9 (Gal-9) expression can be negatively or positively associated with cancer patient prognosis, depending on the cancer type. However, the nature of this relationship remains unclear in multiple myeloma. Therefore, we evaluated the prognostic value of Gal-9 and its relationship with the expression of PD-L1 molecule, the most widely studied immune checkpoint inhibitor, in patients with newly diagnosed multiple myeloma. Gal-9 and PD-L1 levels in bone marrow aspirate samples were evaluated using immunofluorescence assays. Gal-9 positivity was defined as having ≥1% Gal-9-expressing plasma …

Targeting BCL-2 with venetoclax and dexamethasone in patients with relapsed/refractory t(11;14) multiple myeloma.

Venetoclax (Ven) is a selective small-molecule inhibitor of BCL-2 that exhibits antitumoral activity against MM cells with t(11;14) translocation. We evaluated the safety and efficacy of Ven and dexamethasone (VenDex) combination in patients with t(11;14) positive relapsed/refractory (R/R) multiple myeloma (MM). This open-label, multicenter study had two distinct phases (phase one [P1], phase two [P2]). Patients in both phases received VenDex (oral Ven 800 mg/day + oral Dex 40 mg [20 mg for patients ≥75 years] on days 1, 8, and 15, per 21-day cycle). The primary objective of the P1 VenDex coho…

Belantamab Mafodotin to Treat Multiple Myeloma: A Comprehensive Review of Disease, Drug Efficacy and Side Effects.

Multiple myeloma (MM) is a hematologic malignancy characterized by excessive clonal proliferation of plasma cells. The treatment of multiple myeloma presents a variety of unique challenges due to the complex molecular pathophysiology and incurable status of the disease at this time. Given that MM is the second most common blood cancer with a characteristic and unavoidable relapse/refractory state during the course of the disease, the development of new therapeutic modalities is crucial. Belantamab mafodotin (belamaf, GSK2857916) is a first-in-class therapeutic, indicated for patients who have …

Complement C3a activates osteoclasts by regulating the PI3K/PDK1/SGK3 pathway in patients with multiple myeloma.

ObjectiveMyeloma bone disease (MBD) is the most common complication of multiple myeloma (MM). Our previous study showed that the serum levels of C3/C4 in MM patients were significantly positively correlated with the severity of bone disease. However, the mechanism of C3a/C4a in osteoclasts MM patients remains unclear.MethodsThe formation and function of osteoclasts were analyzed after adding C3a/C4a in vitro. RNA-seq analysis was used to screen the potential pathways affecting osteoclasts, and the results were verified by Western blot, qRT-PCR, and pathway inhibitors.ResultsThe osteoclast area…

Management of belantamab mafodotin-associated corneal events in patients with relapsed or refractory multiple myeloma (RRMM).

Belantamab mafodotin (belamaf) demonstrated deep and durable responses in patients with heavily pretreated relapsed or refractory multiple myeloma (RRMM) in DREAMM-2 (NCT03525678). Corneal events, specifically keratopathy (including superficial punctate keratopathy and/or microcyst-like epithelial changes (MECs), eye examination findings with/without symptoms), were common, consistent with reports from other antibody-drug conjugates. Given the novel nature of corneal events in RRMM management, guidelines are required for their prompt identification and appropriate management. Eye examination f…

Circulating miRNAs as Auxiliary Diagnostic Biomarkers for Multiple Myeloma: A Systematic Review, Meta-Analysis, and Recommendations.

Multiple myeloma (MM) is a hematologic malignancy characterized by aberrant expansion of monoclonal plasma cells with high mortality and severe complications due to the lack of early diagnosis and timely treatment. Circulating miRNAs have shown potential in the diagnosis of MM with inconsistent results, which remains to be fully assessed. Here we updated a meta-analysis with relative studies and essays published in English before Jan 31, 2021. After steps of screening, 32 studies from 11 articles that included a total of 627 MM patients and 314 healthy controls were collected. All data were an…

Profile and Management of Toxicity of Selinexor and Belantamab Mafodotin for the Treatment of Triple Class Refractory Multiple Myeloma.

Treatment options are limited for multiple myeloma patients who have developed four/five drug-refractory disease. Selinexor (Sel) and belantamab mafodotin (belamaf) were recently approved by the US FDA for treatment of RRMM. The toxicity profile of these drugs is a concern since these agents are used in patients who have already undergone multiple lines of treatment. In this review, we discuss the toxicity profile and strategies for the management of toxicities of Sel and belamaf for the treatment of RRMM. We conducted a comprehensive literature search on PubMed, Embase, Cochrane, and Clinical…

Decrease in early mortality for newly diagnosed multiple myeloma patients in the Netherlands: a population-based study.

Identification of risk factors for early mortality (EM) in multiple myeloma (MM) patients may contribute to different therapeutic approaches in patients at risk for EM. This population-based study aimed to assess trends in EM and risk factors for EM among MM patients diagnosed in the Netherlands. All MM patients, newly diagnosed between 1989 and 2018, were identified in the Netherlands Cancer Registry. Patients were categorized into three calendar periods (1989-1998, 1999-2008, 2009-2018) and into five age groups (≤65, 66-70, 71-75, 76-80, >80 years). EM was defined as death by any cause ≤180 …

Radiation Therapy can be Safely Incorporated Into Pre-Transplant Treatment Regimens for Patients With Multiple Myeloma.

Purpose/objective(s)Primary treatment of multiple myeloma (MM) often involves systemic induction therapy (SIT) followed by autologous stem cell transplant (ASCT). Radiation therapy (RT) is sometimes used for palliation; however, many practitioners avoid RT out of concern that future peripheral blood progenitor cell (PBPC) collection required for ASCT may be compromised. We retrospectively examined the possible effect of RT on PBPC collection.Materials/methodsWe reviewed the charts of 732 MM patients (pts) seen from 1997-2016 at our institution and included pts who received RT prior to PBPC col…

US Budget Impact Model for Selinexor, Bortezomib, and Dexamethasone for the Treatment of Previously Treated Multiple Myeloma.

PURPOSE: To estimate the budget impact of selinexor, bortezomib, and dexamethasone (XVd) in patients with previously treated multiple myeloma (MM) from the perspective of a private third-party payer and Medicare in the US. METHODS: The introduction of XVd as an option for patients with previously treated MM compared to no introduction of XVd was considered from a private third-party US payer (with 1,000,000 members) and a Medicare perspective in one-year increments for 3 years. Total annual treatment costs were calculated as the sum of drug costs, costs of treating serious treatment emergent …

Prevalence and Survival Impact of Self-Reported Symptom and Psychological Distress Among Patients With Multiple Myeloma.

BACKGROUND: Advances in the management of multiple myeloma (MM) have extended survival and reduced painful skeletal-related events. As MM is evolving toward a chronic disease, we sought to determine the prevalence of self-reported symptom burden and psychological distress, and to determine the association of distress with survival. METHODS: The CPASS-7 patient-reported outcome instrument was administered to a convenience sample of MM patients at 7 outpatient cancer centers. RESULTS: A total of 239 patients completed the CPASS-7 between September 2015 and October 2016%; 57% of respondents wer…

Expression quantitative trait loci of genes predicting outcome are associated with survival of multiple myeloma patients.

Gene expression profiling can be used for predicting survival in multiple myeloma (MM) and identifying patients who will benefit from particular types of therapy. Some germline single nucleotide polymorphisms (SNPs) act as expression quantitative trait loci (eQTLs) showing strong associations with gene expression levels. We performed an association study to test whether eQTLs of genes reported to be associated with prognosis of MM patients are directly associated with measures of adverse outcome. Using the genotype-tissue expression portal, we identified a total of 16 candidate genes with at l…

[Multiple myeloma treated with haploidentical hematopoietic stem cell transplantation with the administration of post-transplant cyclophosphamide].

We report the case of a 58-year-old woman with multiple myeloma who relapsed after the first autologous peripheral blood stem cell transplantation. She was refractory to new drugs and underwent a haploidentical allogeneic hematopoietic stem cell transplantation (haplo-HSCT) by administering post-transplantation cyclophosphamide (PTCy) after the second autologous peripheral blood stem cell transplantation. Neutrophil and platelet engraftment were achieved on days 22 and 55, respectively. Grade II cutaneous acute graft-versus-host disease was observed, which was resolved by systemic steroid trea…

Ultra-low coverage whole genome sequencing of ccfDNA in multiple myeloma: A tool for laboratory routine?

UNLABELLED: Multiple myeloma (MM), is a heterogeneous disease in which chromosomal abnormalities are important for prognostic risk stratification. Cytogenetic profiling with FISH on plasma cells from bone marrow samples (BM-PCs) is the current gold standard, but variable infiltration of plasma cells or failed aspiration can hamper this process. Ultra-low coverage sequencing (ULCS) of circulating cell-free DNA (ccfDNA) may offer a minimally invasive alternative for the work-up of these cases. We compared ULCS, aCGH and FISH on selected BM-PCs in a routine setting with ULCS of ccfDNA for the det…

Outcome of treatment with carfilzomib before and after treatment with daratumumab in relapsed or refractory multiple myeloma patients.

Real world evidence is important since most patients cannot be included in randomized clinical trials (RCTs). In a nationwide, cohort of relapsed/refractory multiple myeloma patients treated with daratumumab (N = 635), we retrospective studied patients treated with carfilzomib (N = 251). Data were collected by audit of medical records. We compared characteristics of patients treated with carfilzomib before daratumumab (Car-Da; N = 150) and after daratumumab (Da-Car; N = 101) with those not treated with carfilzomib (N = 384). Furthermore, we examined effectiveness and safety of carfilzomib. The…

Phase 2 study of venetoclax plus carfilzomib and dexamethasone in patients with relapsed/refractory multiple myeloma.

Proteins in the antiapoptotic B-cell lymphoma 2 (BCL-2) family play a role in the pathophysiology of multiple myeloma (MM). Venetoclax is a highly selective, potent, oral BCL-2 inhibitor that induces apoptosis of MM cells, and its efficacy may be potentiated through combination with agents that increase BCL-2 dependency or have complementary mechanisms of action. The safety, tolerability, pharmacokinetics, and antitumor activity of venetoclax in combination with carfilzomib and dexamethasone (VenKd) in adults with relapsed/refractory MM (RRMM) were investigated in this phase 2 dose-escalation …
