Extramedullary multiple myeloma is defined by the presence of plasma cell infiltration outside of the bone marrow. It is associated with a poor prognosis and resistance to therapy and is often associated with high-risk cytogenetics. Aggressive relapsed and refractory extramedullary multiple myeloma is often treated with salvage infusional chemotherapy to achieve rapid disease control. Commonly used regimens include DCEP, CVAD, and VTD-PACE. While VTD-PACE contains bortezomib and thalidomide which have potent antimyeloma activity, the advent of novel agent therapy with proteasome inhibitors and immunomodulatory agents being used in the first-line setting has resulted in many patients being refractory to bortezomib by the time they are treated with VTD-PACE. Herein, we discuss two cases of aggressive relapsed, high-risk, bortezomib-refractory extramedullary multiple myeloma treated with KRD-PACE and review the available clinical data on salvage chemotherapy regimens used in relapsed refractory myeloma.

Advances in the treatment of multiple myeloma have resulted in dramatic improvements in outcomes for patients. The newly emerging profiling of mutations emerging as a consequence of large prospective sequencing studies such as the CoMMpass Study or other efforts from European investigators are not further helping to define the place and role for personalized medicine in myeloma. While mutations such as NRAS, KRAS, and BRAF do occur in myeloma, it is not clear that targeting them as a single drug strategy will result in meaningful responses or durations of response. Personalized medicine in multiple myeloma at this time likely entails the use of risk-based approaches for maintenance therapy, the use of current biology-based treatments such as proteasome inhibitors, and immunomodulatory agents, with an eye towards the use of mutation-specific treatments in the setting of minimal residual disease or in concert with biology-based treatments overall.

The development of several treatment options over the last 2 decades has led to a notable improvement in the survival of patients with multiple myeloma. Despite these advances, the disease remains incurable for most patients. Moreover, standard combinations of alkylating agents, immunomodulatory drugs, proteasome inhibitors, and monoclonal antibodies targeting CD38 and corticoids are exhausted relatively fast in a proportion of high-risk patients. Such high-risk patients account for over 20% of cases and currently represent a major unmet medical need. The challenge of drug resistance requires the development of highly active new agents with a radically different mechanism of action. Several immunotherapeutic modalities, including antibody–drug conjugates and T-cell engagers, appear to be promising choices for patients who develop resistance to standard combinations. Chimeric antigen-receptor-modified T cells (CAR-Ts) targeting B-cell maturation antigen have demonstrated encouraging efficacy and an acceptable safety profile compared with alternative options. Multiple CAR-Ts are in early stages of clinical development, but the first phase III trials with CAR-Ts are ongoing for two of them. After the recent publication of the results of a phase II trial confirming a notable efficacy and acceptable safety profile, idecabtagene vicleucel is the first CAR-T to gain regulatory US Food and Drug Administration approval to treat refractory multiple myeloma patients who have already been exposed to antibodies against CD38, proteasome inhibitors, and immunomodulatory agents and who are refractory to the last therapy. Here, we will discuss the preclinical and clinical development of idecabtagene vicleucel and its future role in the changing treatment landscape of relapsed and refractory multiple myeloma.

e19521 Background: Daratumumab (dara) with immunomodulatory agents (IMiD) and dexamethasone (dex) is highly effective in relapsed multiple myeloma (MM). The recommended schedule of dara is weekly for 8 doses, followed by 2-weekly for 8 doses, and then every 4-weekly thereafter. Given the high cost and the long half-life as an antibody, a 3-weekly dosing of dara was used together with IMiD/dexamethasone. Methods: Dara at 16mg/kg was used every 3-weekly with lenalidomide or pomalidomide. Patient achieving best response received single agent IMiD maintenance until disease progression. Results: Fourteen relapsed MM patients were enrolled. One had received weekly dara from a private oncologist, hence was excluded from analysis. Thirteen patients at a median age of 63 years (range: 50-84 years) were studied. The median number of previous therapies was 2 (range: 1-5), with nine patients (69.2%) having undergone autologous stem cell transplantation. Three patients (23.1%) were refractory to bortezomib, seven patients (53.8%) to lenalidomide, and eight patients (61.5%) to last treatment. At relapse, two (15.4%) had high LDH, eight (61.5%) impaired renal function, and three (23.1%) extramedullary disease. Treatment was dara-lenalidomide-dex in six (46.2%), and dara-pomalidomide-dex in seven (53.8%). Responses after four cycles included CR in 5 patients (38.5%), VGPR in five patients (38.5%), and PR in three patients (23.1%). After a median of four dara infusions (range: 3-10), the best responses included CR in seven patients (53.8%), nCR in two patients (15.4%), VGPR in two patients (15.4%), and PR in two patients (15.4%). Median time to VGPR was one month. At 10 months, the OS was 90%, and PFS 54.7%. Three patients progressed, one of whom died of ruptured hepatic plasmacytoma. The most frequent toxicity was haematological especially neutropenia (all grades: 92.3%, Grade ¾: 76.9%), infusion reaction (38.5%, all grade ½), neuropathy (38.5%, all grade ½), gastrointestinal (all grades: 38.5%, grade ¾: 7.7%), and sepsis (all grades: 30.8%; grade ¾: 23.1%). Neutropenia was effectively prevented with prophylactic G-CSF. Conclusions: In conclusion , a 3-weekly dara-IMiD-dex regimen is highly efficacious, inducing deep and rapid responses, hence cost-effective for less affluent countries. In view of prevalent grade 3/4 neutropenia despite less frequent dara, 3-weekly dara might be more suitable for Asian patients.

Despite the evolution of the therapeutic arsenal for the treatment of multiple myeloma (MM) over the past decade, autologous stem-cell transplantation (ASCT) remains an integral part of the treatment of patients with both newly diagnosed and relapsed MM. The advent of novel therapies, such as immunomodulatory agents, proteasome inhibitors, and monoclonal antibodies, has led to unprecedented levels of deep hematologic responses. Nonetheless, studies show that ASCT has an additive effect leading to additional deepening of responses. As the therapeutic agents for MM continue to evolve, the timing, duration, and sequence of their use in combination with ASCT will be crucial to understand to obtain the deepest response and survival benefit for patients with MM. This review aims to discuss the role of ASCT for the management of MM, with a particular focus on the role of ASCT in the context of novel therapies and minimal residual disease.

The treatment of multiple myeloma has evolved markedly in the last decade, but mortality remains high, emphasizing the need for more effective therapies. Daratumumab, a fully human monoclonal antibody targeting CD38, has shown clinical efficacy in relapsed/refractory multiple myeloma both as monotherapy and in combination with other drugs, including novel agents. More recently, promising results have been reported in patients with untreated newly diagnosed multiple myeloma (NDMM). Clinical trials thus far have shown enhanced efficacy and tolerability of several daratumumab-based combinations in both transplant ineligible and eligible patients, without compromising transplant ability. However, benefit in high-risk subpopulations is still unclear. A subcutaneous formulation of daratumumab has been introduced to decrease the risk of infusion reactions, with preliminary results showing non-inferior efficacy. The antimyeloma activity of daratumumab is achieved through multiple mechanisms including direct, Fc-dependent, and immunomodulatory mechanisms. Enhanced efficacy of daratumumab in combination with immunomodulatory drugs and proteasome inhibitors is supported by preclinical data showing synergism. This review will focus on the role of daratumumab in untreated NDMM patients, highlighting the results of major clinical trials, and listing ongoing trials that are evaluating various daratumumab-based combinations in this setting.

Functional Inactivation

The progression of multiple myeloma is accompanied by complex cytogenetic and epigenetic alterations that include mutation or functional inactivation of tumor suppressor proteins and overexpression of oncoproteins. Patients whose myeloma is refractory to the three major classes of drugs including immunomodulatory agents, proteasome inhibitors and anti-CD38 monoclonal antibodies have a very poor prognosis. Drugs with novel mechanisms of action that can bypass resistance mechanisms are sorely needed for this group of patients. Selinexor represents a novel, oral agent with an innovative mechanism of action that offers a significant therapeutic advance in this group of heavily treated patients. Moreover, this novel mechanism may provide additional options for patients with less refractory disease.

Abstract At present, multiple classes of agents with distinct mechanisms of action are available for the treatment of patients with multiple myeloma (MM), including alkylators, steroids, immunomodulatory agents (IMiDs), proteasome inhibitors (PIs), histone deacetylase inhibitors (DACIs), and monoclonal antibodies (mAbs). Over the last 5 years, several new agents, such as the third-generation IMiD pomalidomide, the second-generation PIs carfilzomib and ixazomib, the DACI panobinostat, and 2 mAbs, elotuzumab and daratumumab, have been approved, incorporated into clinical guidelines, and have transformed our approach to the treatment of patients. These agents may be part of doublet or triplet combinations, or incorporated into intensive strategies with autologous stem cell transplantation. In this review, I discuss the different treatment options available today for the treatment of MM in frontline and relapse settings.
