We analyzed the treatment of newly diagnosed and relapsed/refractory multiple myeloma (NDMM/RRMM) patients with del(17p). Thirteen prospective studies that evaluated 3,187 MM patients, including 685with del(17p), were included in our meta-analysis. The incidence of del(17p) in NDMM and RRMM patients was similar (13% vs. 14%, respectively, P = 0.64, I2 = 94%). The overall response rate (ORR) to new agents was 40.5% and 67.1%, respectively, in RRMM patients with or without del(17p) (P = 0.1, I2 = 63.9%). NDMM patients with del(17p) treated with PAD (bortezomib, adriamycin, and dexamethasone) induction therapy followed by bortezomib maintenance therapy had higher progression-free survival (PFS) (25...

The histone deacetylase inhibitor panobinostat has shown efficacy in phase-II and phase-III trials for multiple myeloma and has recently received market approval in combination with bortezomib and dexamethasone. Here, we retrospectively report our single center experience with panobinostat/bortezomib/dexamethasone (FVD) in a heavily pretreated patient population (n = 24) with a high degree of refractoriness to proteasome inhibitors (PI) and immunomodulatory drugs (IMiD). Median age was 67 years (range 49-87) and the median number of prior therapies was 5 (range 2-17)...

INTRODUCTION: Lenalidomide is an active agent that was approved for use in the EU in 2015 as a first-line therapy for previously untreated, non-transplant eligible multiple myeloma patients. Our objective was to assess the cost impact of lenalidomide when selected as a first-line treatment for transplant-ineligible patients in France, Germany, Italy, Spain, and the United Kingdom (EU5). METHODS: We developed a cost-impact model of the total costs associated with newly diagnosed multiple myeloma over 5 years in the EU5 based on treatment duration and time to progression (TTP) (taken from trial data)...

The standard treatment of relapsed multiple myeloma (MM) was either lenalidomide-dexamethasone (RD) or bortezomib-dexamethasone (VD) but it is changing rapidly for two reasons. Firstly lenalidomide and bortezomib are currently used in frontline treatment and many patients become resistant to these agents early in the course of their disease. Secondly six second-line new agents have been recently developed and offer new possibilities (pomalidomide, carfilzomib and ixazomib, panobinostat, elotuzumab and daratumumab)...

Proteasome inhibitor carfilzomib has activity superior to bortezomib and is increasingly incorporated in multiple myeloma (MM) frontline therapy and relapsed settings. Most MM patients ultimately experience proteasome inhibitor-refractory disease, an unmet medical need with poorly understood biology and dismal outcome. Pharmacologic targeting of ABCB1 improved patient outcomes, including MM, but suffered from adverse drug effects and insufficient plasma concentrations. Proteomics analysis identified ABCB1 overexpression as the most significant change in carfilzomib-resistant MM cells...

Cell adhesion-mediated drug resistance (CAM-DR) by the bone marrow (BM) is fundamental to multiple myeloma (MM) propagation and survival. Targeting BM protection to increase the efficacy of current anti-myeloma treatment has not been extensively pursued. To extend the understanding of CAM-DR, we hypothesized that the cytotoxic effects of novel anti-myeloma agents may be abrogated by the presence of BM stroma cells (BMSCs) and restored by addition of the CXCL12 antagonist NOX-A12 or the CXCR4 inhibitor plerixafor...

Extensive interindividual variation in response to chemotherapy is a major stumbling block in achieving desirable efficacy in the treatment of cancers, including multiple myeloma (MM). In this study, our goal was to develop a gene expression signature that predicts response specific to proteasome inhibitor (PI) treatment in MM. Using a well-characterized panel of human myeloma cell lines (HMCLs) representing the biological and genetic heterogeneity of MM, we created an in vitro chemosensitivity profile in response to treatment with the four PIs bortezomib, carfilzomib, ixazomib and oprozomib as single agents...

Despite a major positive impact of proteasome inhibitors (PI), such as bortezomib and carfilzomib, on the survival of patients with multiple myeloma (MM) over the last few years, their use in clinical practice is limited by the development of drug resistance, significant side-effects or constraining administration schedules. Ixazomib is the first, and for now the only, oral PI, which was approved by the US Food and Drug Administration in 2015 and by the European Medicines Agency in 2016. Areas covered: In this review, we provide an overview of the preclinical and early-phase studies of ixazomib used as single-agent and in combination...

Introduction of new myeloma therapies offers new options for patients refractory to immunomodulatory drugs (IMiDs) and proteasome inhibitors (PIs). In this multicenter study, patients with relapsed multiple myeloma, who have received at least three prior lines of therapy, are refractory to both an IMiD (lenalidomide or pomalidomide) and a PI (bortezomib or carfilzomib), and have been exposed to an alkylating agent were identified. The time patients met the above criteria was defined as time zero (T0). Five hundred and forty-three patients diagnosed between 2006 and 2014 were enrolled in this study...

Numerous treatments are available for relapsed and/or refractory multiple myeloma (MM), with safety profiles varying across drug classes and across agents within the same class. Thus, it is important to understand the toxicities of each antimyeloma agent when making treatment decisions. Neutropenia is commonly associated with lenalidomide and pomalidomide, and may be common with histone deacetylase (HDAC) inhibitors, but is relatively unusual with thalidomide, bortezomib, and carfilzomib. Infection was common in trials of lenalidomide and pomalidomide, and upper respiratory tract infection and pneumonia have been seen with carfilzomib...

This review discusses the landmark studies in the field of multiple myeloma (MM) which were presented at American society of hematology annual meeting, 2016. There were contrary results from two large phase III trials (one from US and one from Europe) that evaluated the role of additional interventions like tandem autologous transplant (ASCT) and consolidation after induction therapy followed by ASCT in newly diagnosed MM (NDMM) patients, but there were critical differences between the two studies. Novel agents like carfilzomib and ixazomib proved to be of benefit when used as induction and post ASCT consolidation and maintenance in NDMM...

BACKGROUND: Carfilzomib (CFZ) is a new proteasome inhibitor used for the treatment of multiple myeloma. Besides heart failure, angina and myocardial ischemia occurred following administration of CFZ, which is not contraindicated in patients with recent myocardial infarction/unstable angina excluded from the safety trials. AIM OF STUDY: To test the effects of CFZ (10(-9) to 10(-7)mol/L) on vascular tone and reactivity in the isolated rabbit heart and aorta. METHODS AND RESULTS: CFZ administered by bolus injection to the isolated heart increased coronary perfusion pressure (CPP) at all tested concentrations and mildly raised left ventricular pressure and heart rate, only at the highest concentration...

REVIEW
Philippe Moreau, Edwin de Wit
The availability of novel therapies for the treatment of multiple myeloma has had a dramatic impact on the depth of response that can be expected on initial treatment. Despite these advances, disease relapse remains inevitable in most patients and brings with it a different set of priorities for therapy. The most recent wave of novel agents may have a particular impact in the relapsed setting. In this review, we examine the evidence currently available from clinical trials for the use of novel agents, particularly in the formation of triplet therapy...

Objectives and importance: Patients with multiple myeloma (MM) have an increased risk of cardiovascular comorbidities due to disease burden and treatment-related risk factors. Proteasome inhibitors, including bortezomib and carfilzomib, are effective and generally well tolerated anti-MM agents. However, cardiovascular-related toxicities have been reported with this class of agents, the mechanisms of which are not fully understood. We discuss the practical management of cardiovascular events during carfilzomib therapy for relapsed MM...

Multiple myeloma (MM) presents a poor prognosis and high lethality of patients due to development of drug resistance. P-glycoprotein (P-gp), a drug-efflux transporter, is upregulated in MM patients post-chemotherapy and is involved in the development of drug resistance since many anti-myeloma drugs (including proteasome inhibitors) are P-gp substrates. Hypoxia develops in the bone marrow niche during MM progression and has long been linked to chemoresistance. Additionally, hypoxia-inducible transcription factor (HIF-1α) was demonstrated to directly regulate P-gp expression...
