e18096 Background: Newly approved and emerging agents with novel mechanisms of action present unique challenges to treating patients with relapsed/refractory multiple myeloma (RRMM), including keeping abreast of rapid and ever-aggregating data on their safety, tolerability and efficacy. To address these challenges, an education activity focused on new and emerging therapies for RRMM was developed and learner responses were evaluated to determine the impact of education. Methods: A live-online 1-hour video panel discussion with slides, polling, and live questions was produced in 2016 and made available on-demand at OMedLive.com for 6 months. Survey responses (pre-, post-, 8 weeks post-activity), polling responses, and live questions asked were tracked to measure engagement, lessons learned, and additional education gaps. Results: 51 of 288 learners completed all pre/post/follow-up surveys, 67% of which reported the activity positively impacted patient experience or outcome and 61% reported it positively impacted their clinical practice. These learners reported improvements in their ability to: assess the relative safety and efficacy of emerging agents (50%), differentiate available agents and their relative efficacy (50% with proteasome inhibitors, 39% with monoclonal antibodies), see the potential benefit of HDAC inhibitors (35%), use combination regimens (29%), and adjust treatments for patients who’ve experienced disease progression (29%). As the result of education, 95 of 288 learners reported commitments to change in regards to: medical/practice knowledge (95%), care attitudes (89%), practice behavior (76%), and patient clinical outcomes (81%). Learners also demonstrated improved competence via a case scenario which required identifying the optimal next step for a patient with biochemical progression, and improved knowledge on the characteristics of daratumumab, elotuzumab, and selinexor. Conclusions: New and emerging therapies promise to improve the lives of patients with RRMM, but complicates the already difficult task of managing the disease. Ongoing education on RRMM is recommended and can yield immediate and sustained gains in knowledge, competence, and performance.

Novel treatments are needed to address the lack of options for patients with relapsed or refractory multiple myeloma. Even though immunotherapy-based treatments have revolutionized the field in recent years, offering new opportunities for patients, there is still no curative therapy. Thus, non-immunologic agents, which have proven effective for decades, are still central to the treatment of multiple myeloma, especially for advanced disease. Building on their efficacy in myeloma, the development of proteasome inhibitors and immunomodulatory drugs has been pursued, and has led to the emergence of a novel generation of agents (e.g., carfilzomib, ixazomib, pomalidomide). The use of alkylating agents is decreasing in most treatment regimens, but melflufen, a peptide-conjugated alkylator with a completely new mechanism of action, offers interesting opportunities. Moreover, with the identification of novel targets, new drug classes have entered the myeloma armamentarium, such as XPO1 inhibitors (selinexor), HDAC inhibitors (panobinostat), and anti-BCL-2 agents (venetoclax). New pathways are still being explored, especially the possibility of a mutation-driven strategy, as biomarkers and targeted treatments are increasing. Though multiple myeloma is still considered incurable, the treatment options are expanding and are progressively becoming more diverse, largely because of the continuous development of non-immunologic agents.

The Impact

Despite the improvement of patient’s outcome obtained by the current use of immunomodulatory drugs, proteasome inhibitors or anti-CD38 monoclonal antibodies, multiple myeloma (MM) remains an incurable disease. More recently, the testing in clinical trials of novel drugs such as anti-BCMA CAR-T cells, antibody–drug conjugates or bispecific antibodies broadened the possibility of improving patients’ survival. However, thus far, these treatment strategies have not been able to steadily eliminate all malignant cells, and the aim has been to induce a long-term complete response with minimal residual disease (MRD)-negative status. In this sense, approaches that target not only myeloma cells but also the surrounding microenvironment are promising strategies to achieve a sustained MRD negativity with prolonged survival. This review provides an overview of current and future strategies used for immunomodulation of MM focusing on the impact on bone marrow (BM) immunome.

Introduction Real-world evidence on later line treatment of relapsed/refractory multiple myeloma (RRMM) is sparse. We evaluated clinical outcomes among RRMM patients in the 1-year following treatment with pomalidomide or daratumumab and compared economic outcomes between RRMM patients and non-MM patients. Patient and Methods Adult patients with ≥1 claim of pomalidomide or daratumumab were identified between January 2012 and February 2018 using IQVIA PharMetrics® Plus US claims database. Patients were required to have a diagnosis or treatment for MM and a claim of any immunomodulatory drugs and proteasome inhibitors before the index date. Mean time to new therapy, overall survival (OS) using Kaplan-Meier curve and adverse events (AEs) were reported over the 1-year post-index period. RRMM patients were also matched to a non-MM comparator cohort and economic outcomes were compared between the two cohorts. Results 289 RRMM patients were matched to 1,445 patients without MM. Most prevalent hematological AE was anemia (72.0%) and non-hematological AE was infections (75.4%). Mean (SD) time to a new treatment was 4.7 (5.3) months and median OS was 14.6 months. RRMM patients had significantly higher hospitalizations and physician office visits (Both P < .0001) compared to non-MM patients. Adjusting for baseline characteristics, patients with RRMM had 4.9 times (95% CI 3.8-6.4, P < .0001) the total healthcare costs compared with patients without MM. The major driver of total costs among RRMM patients was pharmacy costs (67.3%). Conclusion RRMM patients showed a high frequency of AEs, low OS, and a substantial economic burden suggesting need for effective treatment options.

Risk Patients

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.

Safe Dose

M3258 is an orally bioavailable, potent, selective, reversible inhibitor of the large multifunctional peptidase 7 (LMP7, β5i, PSMB8) proteolytic subunit of the immunoproteasome; a crucial component of the cellular protein degradation machinery, which is highly expressed in malignant hematopoietic cells including multiple myeloma. M3258 was previously shown to deliver strong in vivo preclinical efficacy in multiple myeloma xenograft models, as well as a more benign non-clinical safety profile compared to approved pan-proteasome inhibitors, exemplified by a lack of effects on the central and peripheral nervous systems and cardiac and respiratory organs. Here we describe preclinical PK/PD and PK/efficacy modelling which led to a prediction of the PK profile, and the efficacious and safe dose ranges of M3258 in human which were used to guide the design of the phase I dose-escalation trial of M3258 in >3 line relapsed/refractory multiple myeloma (RRMM) patients. Mouse, rat, dog and monkey PK, plasma protein binding and intrinsic clearance data were used to estimate a half-life of approximately 6 hours for M3258 in human. The human total clearance and volume of distribution for M3258 were predicted to be 0.033 L/h/kg and 0.28 L/kg, respectively, whilst oral bioavailability was estimated to be above 80%. LMP7 proteolytic activity was assessed as a PD readout in human multiple myeloma tumor cells xenografted to mice as well as in dog peripheral blood mononuclear cells (PBMCs). A strong PK/PD relationship was observed for M3258 across both species. LMP7 inhibition by M3258 also correlated strongly with anti-tumor efficacy in multiple myeloma xenografts, with maximal efficacy observed at M3258 exposure delivering sustained inhibition of tumor LMP7 activity. Quantitative PK/PD/efficacy modeling predicted the biologically efficacious dose (BED) of M3258 upon oral application to be between 10 - 90 mg daily in human. By incorporating data from nonclinical safety studies, these data suggest an attractive human PK profile of M3258, enabling oral application, as well as an improved human therapeutic index compared to approved pan-proteasome inhibitors. M3258 is being investigated in a phase I, first-in-man, 2-part, open label clinical study designed to determine the safety, tolerability, PK, PD and early signs of efficacy of M3258 as a single agent (dose-escalation) and co-administered with dexamethasone (dose-expansion) in participants with RRMM whose disease has progressed following > 3 prior lines of therapy and for whom no effective standard therapy exists. Integration of these data will guide the selection of the BED for potential further clinical development of M3258. Disclosures Lignet: Merck Healthcare KGaA: Employment.

Current Guidelines

The introduction of carfilzomib in the treatment of relapsing and refractory multiple myeloma has allowed a significant increase in survival. The most frequent adverse effect of Carfilzomib treatment is arterial hypertension, even though the exact physiopathological mechanism are still unclear. MM patients, on the other hand, often present significant cardiovascular risk factors and comorbidities. Uncontrolled hypertension is frequently the cause of cardiovascular complications. It has been estimated that up to 50% of subjects in the general population are unaware of their hypertensive condition and only half of those who are aware of this risk factor present good control of blood pressure. Although the management of arterial hypertension is clearly important in reducing the risk of cardiovascular events, and is well described by the current guidelines, no clear indications are provided on how to approach and treat specifically MM patients undergoing treatment with proteasome inhibitors. The aim of our work is to summarize a practical approach to the stratification of cardiovascular risk of hypertensive in patients who are candidates for or actively treated with carfilzomib for refractory multiple myeloma (MMR). MM patients eligible for carfilzomib treatment should preliminary undergo a careful cardiovascular risk stratification. Perspective studies will help to better identify the specific risk factors that should be considered and treated in these patients.

AbstractMultiple available combinations of proteasome inhibitors, immunomodulators (IMIDs), and monoclonal antibodies are shifting the relapsed/refractory multiple myeloma (RRMM) treatment landscape. Lack of head-to-head trials of triplet regimens highlights the need for real-world (RW) evidence. We conducted an RW comparative effectiveness analysis of bortezomib (V), carfilzomib (K), ixazomib (I), and daratumumab (D) combined with either lenalidomide or pomalidomide plus dexamethasone (Rd or Pd) in RRMM. A retrospective cohort of patients initiating triplet regimens in line of therapy (LOT) ≥ 2 on/after 1/1/2014 was followed between 1/2007 and 3/2018 in Optum’s deidentified US electronic health records database. Time to next treatment (TTNT) was estimated using Kaplan-Meier methods; regimens were compared using covariate-adjusted Cox proportional hazard models. Seven hundred forty-one patients (820 patient LOTs) with an Rd backbone (VRd, n = 349; KRd, n = 218; DRd, n = 99; IRd, n = 154) and 348 patients (392 patient LOTs) with a Pd backbone (VPd, n = 52; KPd, n = 146; DPd, n = 149; IPd, n = 45) in LOTs ≥2 were identified. More patients ≥75 years received IRd (39.6%), IPd (37.8%), and VRd (36.7%) than other triplets. More patients receiving VRd/VPd were in LOT2 vs other triplets. Unadjusted median TTNT in LOT ≥ 2: VRd, 13.9; KRd, 8.7; IRd, 11.4; DRd, not estimable (NE); and VPd, 12.0; KPd, 6.7; IPd, 9.5 months; DPd, NE. In covariate-adjusted analysis, only KRd vs DRd was associated with a significantly higher risk of next LOT initiation/death (HR 1.72; P = 0.0142); no Pd triplet was significantly different vs DPd in LOT ≥ 2. Our data highlight important efficacy/effectiveness gaps between results observed in phase 3 clinical trials and those realized in the RW.
