Abstract
Immense progress has been made for the treatment of multiple myeloma over the past two decades, with patient outcomes improving dramatically as a result. Patient quality of life, however, is constantly challenged by complications of the disease, side effects of therapy and the overall burden receiving continuous treatment. Compared to parenteral agents, all-oral regimens can provide logistically favorable alternatives and are associated with improved quality of life. Here, we review the currently available and investigational oral therapies for relapsed and refractory multiple myeloma and provide a practical clinical reference tool. We explore the factors that dictate the selection of therapy, such as prior drug refractoriness, disease biology and patient-specific considerations. Regimens with their respective supporting clinical data are organized by the degree of prior treatment, from lenalidomide-sensitive to heavily pretreated patients. We explore common challenges such as renal insufficiency and cytopenias. Lastly, we review investigational oral agents.

Long-Term Effectiveness and Cost Effectiveness of Multiple Myeloma Treatment Strategies for Elderly Transplant-Ineligible Patients in Serbia. Zdr Varst 2020; 59:83-91. [PMID: 32952707 PMCID: PMC7478073 DOI: 10.2478/sjph-2020-0011] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/02/2019] [Accepted: 02/13/2020] [Indexed: 01/14/2023] Open
Abstract
Introduction Evidence on long-term effectiveness and cost effectiveness of treatment sequences for multiple myeloma (MM) is sparse. We used published data and country-specific data to assess the cost effectiveness of four-line treatment sequences for elderly transplant-ineligible patients with MM in Serbia. Method We developed a Markov cohort model to compare long-term effectiveness and cost effectiveness of five sequential MM treatment alternatives from the perspective of the national healthcare provider. Effectiveness parameters on progression, mortality and adverse events were extracted from published clinical trials. Costs were based on price lists of the National Health Insurance Fund. We compared life expectancy, costs, and incremental cost-effectiveness ratios among alternative courses of action. The model was analyzed over a lifelong time horizon applying a 3% annual discount rate for effectiveness outcomes and costs. Robustness of the model was tested in multiple deterministic sensitivity analyses. Results The sequences were defined by the frontline treatment: MPT (melphalan-prednisone-thalidomide), MPV (melphalanprednisone-bortezomib), CTD (cyclophosphamide-thalidomide-dexamethasone), VCD (bortezomib-cyclophosphamidedexamethasone) and BP (bendamustine-prednisone). MPV sequence resulted in the highest remaining life expectancy (4.76 life years). Cost-effectiveness analysis resulted in three non-dominated strategies: MPT, VCD, and MPV sequences, with an incremental cost-effectiveness ratio of EUR 35,300 per life-year gained (LYG) for VCD and EUR 47,200/LYG for MPV relative to MPT. Conclusion MPV sequence was the most effective in terms of life expectancy for elderly transplant-ineligible MM patients in Serbia. Bortezomib-based strategies would be recommended for the frontline treatment of patients with MM in Serbia if the willingness-to-pay threshold is around EUR 35,000-60,000/LYG.

Abstract
BACKGROUND For patients with multiple myeloma (MM) that relapsed after treatment with bortezomib- and lenalidomide-based regimens, there were no other treatment options in Korea until 2016. We aimed to determine the efficacy of thalidomide plus dexamethasone-based regimens in patients with relapsed/refractory MM (RRMM). PATIENTS AND METHODS We conducted a multicenter retrospective analysis in Korea for patients with RRMM treated with thalidomide-based regimens who previously received bortezomib and immunomodulatory agents (IMiDs), including thalidomide and lenalidomide. RESULTS In 47 patients with RRMM, the median age was 64 years and the median number of previous treatment lines, including bortezomib and IMiDs, was 3. Primary resistance to bortezomib and lenalidomide was observed in 12 (26%) and 8 (17%) patients, respectively. The most common regimen was a combination of thalidomide, cyclophosphamide, and dexamethasone. The overall response rate was 38%; 2 patients (4%) experienced a complete response, and 2 patients (4%) experienced a very good partial response. The overall response rate of patients previously exposed to thalidomide was 53%. The median progression-free survival was 5.9 months, and overall survival was 9.2 months. Patients with disease that responded to the thalidomide-based regimen had better progression-free survival compared to those who did not (median, 8.8 vs. 2.5 months; P = .008). The most common adverse events were anemia (51%) for hematologic toxicities and peripheral neuropathy (30%) for nonhematologic toxicities. CONCLUSION Thalidomide-based regimens are potential salvage treatment options for patients with RRMM, even those with disease with prior resistance to IMiDs.

Abstract
The long-term outcome of multiple myeloma (MM) has been greatly improved through new agents, one being lenalidomide (LEN). Based upon the findings of in vitro experiments, its mode of action against MM occurs through a combination of direct tumoricidal effects on myeloma cells, modulatory effects on tumor immunity and tumor microenvironment-regulatory effects. However, it has not been clearly defined whether the clinical response and long-term outcome of MM with LEN treatment truly reflect the mechanisms of action of LEN proposed by in vitro studies. To ascertain what is known and what remains to be elucidated with LEN, we review the current literature on the mode of action of LEN in association with myeloma pathophysiology, and discuss the prognostic indicators in the treatment of MM with LEN.

Abstract
In recent years, the treatment of multiple myeloma has undergone significant changes. The availability of novel agents bortezomib, thalidomide and lenalidomide considerably improved the outcome of patients. The advantages related to the use of novel agents have been shown in various studies in patients eligible and ineligible for transplant. In elderly patients, novel agents have also revolutionized the treatment paradigm and have replaced the traditional melphalan-prednisone regimen. A sequential approach consisting of an induction regimen associated with a high rate of complete response, followed by consolidation/maintenance therapy, induces a profound cytoreduction and delays relapse, thus improving survival. Patients older than 75 years or who are otherwise vulnerable are more susceptible to adverse events. In this setting, less toxic regimens and appropriate dose-reductions should be adopted. This article provides an overview of the main trials for transplant-ineligible multiple myeloma patients. Recommendations on how to manage unfit patients and treatment-related toxicities are also provided.

Abstract
We conducted a retrospective analysis of lenalidomide with dexamethasone for patients with relapsed/refractory multiple myeloma (RRMM) who were treated within the Korean patient access program. Lenalidomide has been approved for RRMM for several years in Europe and North America, but has not been accessible to Asian patients in the past. Between 2008 and 2012, 110 patients from 20 hospitals were enrolled. The overall response rate (ORR) was 43.6 % with 15.4 % of very good partial response (VGPR) or better. The median time to progression (TTP) in this heavily pretreated patient population was 8.0 months, and median overall survival (OS) was 23 months. Hematologic toxicities, fatigue, anorexia, and constipation were the most common adverse events. The number of previous treatment lines, previous exposure to thalidomide, refractoriness to thalidomide and bortezomib, pretreatment white blood cell count (WBC), platelet count, t(14;16), and 17p deletion were significant prognostic factors for TTP, and creatinine clearance, refractoriness to thalidomide and bortezomib, performance status, platelet count, and 17p deletion were significant for OS in univariate analysis. In multivariate analysis, WBC and platelet count were significant prognostic factors for TTP and performance status for OS. For Korean myeloma patients, lenalidomide showed considerable efficacy, and toxicities were comparable to the data published in Europe and North America.

Abstract
Lenalidomide is a distinct second-generation immunomodulatory drug with multiple anticancer and immunomodulatory effects against hematologic malignancies, in particular multiple myeloma (MM). Dexamethasone synergistically enhances the anticancer effects of lenalidomide, and the combination of lenalidomide and dexamethasone (Len/Dex) is approved for the treatment of patients with relapsed and/or refractory MM. Results from pivotal phase III trials in this setting have demonstrated that Len/Dex extends overall survival compared with dexamethasone alone. Optimal clinical benefits are seen when Len/Dex is initiated at first relapse and continued, beyond best treatment response, until disease progression. Lenalidomide based regimens are also effective as induction therapy in patients with newly diagnosed MM. Importantly, lenalidomide has a predictable and manageable tolerability profile, with minimal neurotoxicity, allowing long-term administration. As the paradigm of myeloma disease continues to change, future studies will determine the efficacy of lenalidomide in novel combinations with potentially complimentary agents.

Abstract
In Canada, lenalidomide combined with dexamethasone (Len/Dex) is approved for use in relapsed or refractory multiple myeloma (RRMM). Our expert panel sought to provide an up-to-date practical guide on the use of lenalidomide in the managing RRMM within the Canadian clinical setting, including management of common adverse events (AEs). The panel concluded that safe, effective administration of Len/Dex treatment involves the following steps: (1) lenalidomide dose adjustment based on creatinine clearance and the extent of neutropenia or thrombocytopenia, (2) dexamethasone administered at 20-40 mg/week, and (3) continuation of treatment until disease progression or until toxicity persists despite dose reduction. Based on available evidence, the following precautions should reduce the risk of common Len/Dex AEs: (1) all patients treated with Len/Dex should receive thromboprophylaxis, (2) erythropoiesis-stimulating agents (ESAs) should be used cautiously, and (3) females of child-bearing potential and males in contact with such females must use multiple contraception methods. Finally, while Len/Dex can be administered irrespective of prior therapy and in all prognostic subsets, patients with chromosomal deletion 17(p13) have less favorable outcomes with all treatments, including Len/Dex. New directions for the use of lenalidomide in RRMM are also considered.

Abstract
Although several mechanisms have been proposed to explain the activity of thalidomide, lenalidomide and pomalidomide in multiple myeloma (MM), including demonstrable anti-angiogenic, anti-proliferative and immunomodulatory effects, the precise cellular targets and molecular mechanisms have only recently become clear. A landmark study recently identified cereblon (CRBN) as a primary target of thalidomide teratogenicity. Subsequently it was demonstrated that CRBN is also required for the anti-myeloma activity of thalidomide and related drugs, the so-called immune-modulatory drugs (IMiDs). Low CRBN expression was found to correlate with drug resistance in MM cell lines and primary MM cells. One of the downstream targets of CRBN identified is interferon regulatory factor 4 (IRF4), which is critical for myeloma cell survival and is down-regulated by IMiD treatment. CRBN is also implicated in several effects of IMiDs, such as down-regulation of tumor necrosis factor-α (TNF-α) and T cell immunomodulatory activity, demonstrating that the pleotropic actions of the IMiDs are initiated by binding to CRBN. Future dissection of CRBN downstream signaling will help to delineate the underlying mechanisms for IMiD action and eventually lead to development of new drugs with more specific anti-myeloma activities. It may also provide a biomarker to predict IMiD response and resistance.

Abstract
Mucosa associated lymphoid tissue lymphoma shares certain features with multiple myeloma. In view of this and the activity of lenalidomide in various B-cell lymphomas, we have initiated a phase II study of lenalidomide in patients with mucosa associated lymphoid tissue lymphoma. Patients with histologically verified advanced stages of this lymphoma were included in the study. Treatment consisted of oral lenalidomide 25 mg Days 1-21, with a 7-day break after each cycle. A total of 18 patients were included in the trial: 5 had gastric and 13 had extragastric mucosa associated lymphoid tissue lymphoma, but 2 discontinued therapy during the first course of therapy. In the intent to treat analysis, an overall response rate of 61% was seen (11 of 18; 6 complete and 5 partial remissions). Three patients had stable disease while 2 progressed. Side effects were manageable and included neutropenia (grade III in 3 patients) as the leading hematotoxicity. After a median follow up of 20.3 months, one patient has died from lymphoma while the remaining patients are alive and relapse-free. These data suggest activity of lenalidomide monotherapy in mucosa associated lymphoid tissue lymphoma. The study protocol had been approved by the Ethical Board of the Medical University Vienna (EK-No.: 146/09), and before opening the trial, it had been registered at www.clinicaltrials.gov. (identifier: NCT00923663).

Abstract
Lenalidomide is an amino-substituted derivative of thalidomide with direct antiproliferative and cytotoxic effects on the myeloma tumor cell, as well as antiangiogenic activity and immunomodulatory effects. Together with the introduction of bortezomib and thalidomide, lenalidomide has significantly improved the survival of patients with relapsed and refractory myeloma. The most common adverse events associated with lenalidomide include fatigue, skin rash, thrombocytopenia, and neutropenia. In addition, when lenalidomide is combined with dexamethasone or other conventional cytotoxic agents, there is an increase in the incidence of venous thromboembolic events. There is now evidence that continued treatment with lenalidomide has a significant impact on survival by improving the depth and duration of response. This highlights the value of adverse event management and appropriate dose adjustments to prevent toxicity, and of allowing continued treatment until disease progression. In this review, we will discuss the different lenalidomide-based treatment regimens for patients with relapsed/refractory myeloma. This is accompanied by recommendations of how to manage and prevent adverse events associated with lenalidomide-based therapy.

Abstract
Treatment of multiple myeloma has evolved over the last decade, most notably with the introduction of highly effective novel agents. It is now possible to aim for deep disease responses in a greater number of patients in an attempt to prolong remission duration and survival. Initially introduced in the relapsed setting, the novel agents, namely thalidomide, bortezomib and lenalidomide, are now being increasingly incorporated into upfront treatment strategies, raising questions about the feasibility of 'retreatment' with such agents. Also, in a disease that is characterized by multiple relapses, the 'sequencing' of the different effective options is an important question. In the frontline setting, the first remission is likely to be the period during which patients will enjoy the best quality of life. Thus, the goal should be to achieve a first remission that is the longest possible by using the most effective treatment upfront. At relapse, the challenge is to select the optimal treatment for each patient while balancing efficacy and toxicity. The decision will depend on both disease- and patient-related factors. This review aimed to assess the available research data addressing 'retreatment' approaches, drug 'sequencing' and the long-term impact of upfront therapy with novel drugs.
