AbstractConsiderable progress has been made in the treatment of multiple myeloma in the past decade with median survival for the disease improving significantly. This has come through a combination of better understanding of the disease biology and coordinated research into new treatment approaches including better supportive care. However, patients eventually become refractory to available treatments and succumb to the disease, highlighting the need to develop new treatment approaches. The genetic heterogeneity in the disease and clonal evolution under treatment pressure underlie the development of resistance, underscoring the need to develop more effective therapies that can eradicate the disease at initial treatment as well as the need for new classes of drugs with varying mechanisms of action. To this end, there has been intense focus on exploring novel approaches to therapy including small-molecule inhibitors targeting specific abnormalities, immune therapies including monoclonal antibodies and adaptive T-cell therapy, as well as epigenetic approaches. Although many of these drugs are in the early stages of clinical development, the early data appear to be very promising. Many of these drugs can be safely and effectively combined with the current treatment classes such as proteasome inhibitors and immunomodulatory drugs, further enhancing the treatment options for myeloma.

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.

Immune Therapies

The treatment options in multiple myeloma (MM) has changed dramatically over the past decade with the development of novel agents such as proteasome inhibitors (PIs); bortezomib and immunomodulatory drugs (IMiDs); thalidomide, and lenalidomide which revealed high efficacy and improvement of overall survival (OS) in MM patients. However, despite these progresses, most patients relapse and become eventually refractory to these therapies. Thus, the development of novel, targeted immunotherapies has been pursued aggressively. Recently, next-generation PIs; carfilzomib and ixazomib, IMiD; pomalidomide, histone deacetylase inhibitor (HDADi); panobinostat and monoclonal antibodies (MoAbs); and elotuzumab and daratumumab have emerged, and especially, combination of mAbs plus novel agents has led to dramatic improvements in the outcome of MM patients. The field of immune therapies has been accelerating in the treatment of hematological malignancies and has also taken center stage in MM. This review focuses on an overview of current status of novel MoAb therapy including bispecific T-cell engager (BiTE) antibody (BsAb), antibody-drug conjugate (ADC), and chimeric antigen receptor (CAR) T cells, in relapsed or refractory MM (RRMM). Lastly, investigational novel MoAb-based therapy to overcome immunotherapy resistance in MM is shown.

Cardiovascular disease (CVD) is the leading cause of death globally. Current treatment options include lifestyle changes, medication, and surgical intervention. However, many patients are unsuitable candidates for surgeries due to comorbidities, diffuse coronary artery disease or advanced stages of heart failure. The search for new treatment options has recently transitioned from cell-based therapies to stem-cell derived extracellular vesicles (EVs). A number of challenges remain in the EV field, including the effect of comorbidities, characterization, and delivery, However, recent revolutionary developments and insight into the potential of 'personalizing' EV contents by bioengineering methods to alter specific signaling pathways in the ischemic myocardium hold promise. Here, we discuss the past limitations of cell-based therapies, and recent EV studies involving in vivo, in vitro, and omics, and future challenges and opportunities in EV-based treatments in CVD.

Abstract In multiple myeloma (MM), treatment selection and sequencing become increasingly complex with the increasing number of therapeutic options, including antibodies. Choice of treatment is dependent on various factors including patient- and tumor-related features. In addition, treatment-related factors, such as type and response to prior therapy, are also critical in terms of the selection of a new treatment regimen. Furthermore, approval status and reimbursement policies influence treatment choice. At the time of first relapse, patients who received a bortezomib-based regimen can switch to lenalidomide-based treatment, whereas patients who received lenalidomide until progression can switch to a proteasome inhibitor–based therapy. Alternatively, there is increasing evidence that pomalidomide-based triplets are also effective following the development of lenalidomide-refractory disease both in early and later relapse settings. Patients who become refractory to immunomodulatory drugs, proteasome inhibitors, and CD38 antibodies have a poor prognosis. These triple-class refractory patients may benefit from novel, recently approved agents such as XPO1 inhibitors or from participation in a clinical trial. Furthermore, retreatment with agents that were received in previous lines of therapy can also be considered in heavily pretreated patients, for example, in combination with classic cytotoxic drugs. Importantly, with the increasing use of CD38 antibodies in newly diagnosed and early relapsed/refractory MM, more information is needed on the potential value of retreatment with CD38 antibodies. With the introduction of new immunotherapies with novel modes of action, we also need a better understanding of sequencing of immunotherapeutic agents by taking into account the effect of prior therapy on immune function.

Abstract Multiple myeloma (MM) is a unique cancer paradigm for investigating the mechanisms involved in the transition from a premalignant condition (monoclonal gammopathy of undetermined significance) into a malignant disease (MM). In the pathogenesis of myeloma, the dialogue between plasma cells and their microenvironment is as important as the genotypic characteristics of the tumor clone. MM is genetically highly complex, with almost all patients displaying cytogenetic abnormalities and frequent intraclonal heterogeneity that play a critical role in the outcome of the disease. In fact, it is likely that myeloma will soon no longer be considered as a single entity. This, along with the availability of an unexpected number of new treatment possibilities, has reinforced the need for better tools for prognosis and for monitoring treatment efficacy through minimal residual disease techniques. The outcome of MM patients has significantly improved in the last 2 decades, first through the introduction of high-dose therapy followed by autologous stem cell transplantation and, more recently, due to the use of proteasome inhibitors (bortezomib and carfilzomib) and immunomodulatory agents (thalidomide, lenalidomide, and pomalidomide). Moreover, the need to reexamine the diagnostic criteria of early MM and the possibility of early intervention opens up new therapeutic avenues. New drugs are also emerging, including second- and third-generation proteasome inhibitors and immunomodulators, monoclonal antibodies, histone deacetylase inhibitors, and kinesin spindle protein inhibitors, among others. Our goal is to find a balance among efficacy, toxicity, and cost, with the ultimate aim of achieving a cure for this disease.

AbstractSmoldering multiple myeloma (SMM) is an asymptomatic clonal plasma cell disorder. SMM is distinguished from monoclonal gammopathy of undetermined significance by a much higher risk of progression to multiple myeloma (MM). There have been major advances in the diagnosis, prognosis, and management of SMM in the last few years. These include a revised disease definition, identification of several new prognostic factors, a classification based on underlying cytogenetic changes, and new treatment options. Importantly, a subset of patients previously considered SMM is now reclassified as MM on the basis of biomarkers identifying patients with an ≥80% risk of progression within 2 years. SMM has assumed greater significance on the basis of recent trials showing that early therapy can be potentially beneficial to patients. As a result, there is a need to accurately diagnose and risk-stratify patients with SMM, including routine incorporation of modern imaging and laboratory techniques. In this review, we outline current concepts in diagnosis and risk stratification of SMM, and provide specific recommendations on the management of SMM.

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.

Degenerative disc disease (DDD) is a painful, chronic and progressive disease, which is characterized by inflammation, structural and biological deterioration of the intervertebral disc (IVD) tissues. DDD is specified as cell-, age-, and genetic-dependent degenerative process that can be accelerated by environmental factors. It is one of the major causes of chronic back pain and disability affecting millions of people globally. Current treatment options, such as physical rehabilitation, pain management, and surgical intervention, can provide only temporary pain relief. Different animal models have been used to study the process of IVD degeneration and develop therapeutic options that may restore the structure and function of degenerative discs. Several research works have depicted considerable progress in understanding the biological basis of disc degeneration and the therapeutic potentials of cell transplantation, gene therapy, applications of supporting biomaterials and bioactive factors, or a combination thereof. Since animal models play increasingly significant roles in treatment approaches of DDD, we conducted an electronic database search on Medline through June 2020 to identify, compare, and discuss publications regarding biological therapeutic approaches of DDD that based on intradiscal treatment strategies. We provide an up-to-date overview of biological treatment strategies in animal models including mouse, rat, rabbit, porcine, bovine, ovine, caprine, canine, and primate models. Although no animal model could profoundly reproduce the clinical conditions in humans; animal models have played important roles in specifying our knowledge about the pathophysiology of DDD. They are crucial for developing new therapy approaches for clinical applications.
