Abstract
BACKGROUND This guideline has been developed jointly by the European Society of Haematology and International Society of Amyloidosis recommending non-transplant chemotherapy treatment for patients with AL amyloidosis. METHODS A review of literature and grading of evidence as well as expert recommendations by the ESH and ISA guideline committees. RESULTS AND CONCLUSIONS The recommendations of this committee suggest that treatment follows the clinical presentation which determines treatment tolerance tempered by potential side effects to select and modify use of drugs in AL amyloidosis. All patients with AL amyloidosis should be considered for clinical trials where available. Daratumumab-VCD is recommended from most untreated patients (VCD or VMDex if daratumumab is unavailable). At relapse, the two guiding principles are the depth and duration of initial response, use of a class of agents not previously exposed as well as the limitation imposed by patients' fitness/frailty and end organ damage. Targeted agents like venetoclax need urgent prospective evaluation. Future prospective trials should include advanced stage patients to allow for evidence-based treatment decisions. Therapies targeting amyloid fibrils or those reducing the proteotoxicity of amyloidogenic light chains/oligomers are urgently needed.

Post-marketing safety of immunomodulatory drugs in multiple myeloma: A pharmacovigilance investigation based on the FDA adverse event reporting system. Front Pharmacol 2022; 13:989032. [PMID: 36532784 PMCID: PMC9751748 DOI: 10.3389/fphar.2022.989032] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/08/2022] [Accepted: 11/18/2022] [Indexed: 06/10/2024] Open
Abstract
Objective: In recent years, the emergence of immunomodulatory drugs (IMiDs) has significantly improved clinical outcomes in patients with multiple myeloma (MM); however, serious adverse events (AEs) have hindered their safe clinical application. This study aimed to characterize the safety profiles and differences in IMiDs through a disproportionality analysis using the U.S. Food and Drug Administration Adverse Event Reporting System (FAERS), a post-marketing surveillance database. Methods: This study filtered reports of thalidomide, lenalidomide, and pomalidomide as primary suspect drugs in FAERS files from January 2013 to December 2021. AEs in the reports were retrieved according to the preferred terms (PTs) of the Medical Dictionary for Regulatory Activities. Furthermore, we detected safety signals using the reporting odds ratio (ROR), proportional reporting ratio (PRR), and Bayesian belief propagation neural network (BCPNN). When all three algorithms showed an association between the target drug and the AE, a positive signal was generated. Results: We extracted 9,968 thalidomide, 231,926 lenalidomide, and 55,066 pomalidomide AE reports. AEs were more common in male patients and in those >44 years old. Important safety signals were detected based on the system organ classes (SOC), including thalidomide (cardiac disorders: ROR, 2.87; PRR, 2.79; IC 1.22), lenalidomide (gastrointestinal disorders: ROR, 2.38; PRR, 2.27; IC 0.75), and pomalidomide (respiratory, thoracic, and mediastinal disorders: ROR, 2.14; PRR, 2.09; IC 0.85). Within the PT level, we identified novel risk signals: the thalidomide-induced second primary malignancy (SPM) signal was significant; lenalidomide reduced the success rate of hematopoietic stem cell collection; and three IMiDs may cause human chorionic gonadotropin increase, but this needs to be proven by clinical data. Pneumonia, sepsis, and renal failure are common risk factors for death due to IMiDs. Compared with thalidomide and lenalidomide, pomalidomide has a lower risk of venous thromboembolism (VTE) and is beneficial to patients with renal insufficiency. Conclusion: Mining data from FAERS resulted in novel AE signals, including adenocarcinoma of colon, harvest failure of blood stem cells, and increased levels of human chorionic gonadotropin. Further investigation is required to verify the significance of these signals. Moreover, IMiDs showed differences in safety reports, which should be emphasized by clinicians.

Abstract
BACKGROUND Induction therapy is recommended before autologous stem cell transplantation (ASCT) for AL amyloidosis patients with high disease burden [bone marrow plasma cells (BMPCs) > 10%], but the role of induction therapy before ASCT in patients with low disease burden (BMPCs ≤ 10%) is still unknown. METHODS A total of 227 patients with AL amyloidosis were included in this study. Among 227 patients, 124 patients received bortezomib-based induction prior to ASCT and were defined as group A, 35 patients received other chemotherapeutic induction and were defined as group B, and the other 68 patients without induction were defined as group C. We compared the differences of efficacy and prognosis between the three groups. RESULTS The haematological overall response rates (ORR) of groups A, B and C were 91%, 67% and 75%, respectively. The complete response rates (CR) of groups A, B and C were 50%, 25% and 20%, respectively. Both the ORR and CR rates of group A were significantly higher than those of groups B and C. The renal response rates of groups A, B and C were 64%, 46% and 47%, respectively. The cardiac response rates of groups A, B and C were 74%, 45% and 40%, respectively. The renal and cardiac responses rates of group A were also significantly higher than those of the other two groups. After a median follow-up of 44 months, the median OS was not reached. The 5-year estimated overall survival (OS) rates of groups A, B and C were 81%, 57% and 67%, respectively. The median progression-free survival (PFS) was 83 months for all patients. The 5-year estimated PFS rates of groups A, B and C were 61%, 38% and 49%, respectively. Both the OS and PFS of group A were higher than those of both group B and group C. On multivariate analysis, baseline dFLC > 50 mg/L was associated with worse survival, but induction with bortezomib was associated with better survival. CONCLUSION Our study demonstrated that low disease burden AL patients who are eligible for ASCT may benefit from bortezomib-based induction therapy.

First-line daratumumab shows high efficacy and tolerability even in advanced AL amyloidosis: the real-world experience. ESMO Open 2021; 6:100065. [PMID: 33667762 PMCID: PMC7937667 DOI: 10.1016/j.esmoop.2021.100065] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/19/2020] [Revised: 01/08/2021] [Accepted: 01/24/2021] [Indexed: 11/25/2022] Open
Abstract
Background Daratumumab was the first monoclonal CD38 antibody with single-agent activity approved for the treatment of multiple myeloma. Moreover, daratumumab demonstrated high response rates in relapsed immunoglobulin light-chain (AL) amyloidosis. Patients and methods In our single-center retrospective real-life case series, we analyzed the efficacy and safety of daratumumab as first-line treatment. Daratumumab was administered with low-dose dexamethasone alone or in combination with other multiple myeloma therapeutics Results Fourteen patients were eligible, including nine patients with cardiac stage IIIa or IIIb. Overall hematologic response rate was 100%, with 64.3% achieving complete response after a median of 16 cycles of treatment. Median time to hematologic response was 1.4 months. Organ response rates were 45.5% after a median of 4.0 months and 66.7% after a median of 10.0 months, for heart and kidney involvement, respectively. After a median follow-up of 20.5 months, two patients underwent successful autologous stem cell transplantation (ASCT), while another three patients were in preparation for ASCT. Three patients remained on daratumumab at the last follow-up. There were no unexpected toxicities and no grade III or IV adverse events, although more than half of our patients were in stage IIIa or IIIb. Conclusion Daratumumab proved to be highly effective in newly diagnosed AL amyloidosis with excellent hematologic and organ response rates, a remarkable safety profile, and good tolerability even in patients with advanced stage of disease. Daratumumab yields high hematologic response rates in untreated AL amyloidosis. Treatment is well tolerated even in advanced disease stages. No unexpected toxicity was observed.

Abstract
Immunoglobulin light-chain amyloidosis (AL amyloidosis) is a rare disease in which a small plasma cell clone produces toxic misfolded proteins that deposit in organs and impair their function. Currently, the only available treatment approach is the elimination of clonal plasma cells. However, a rapid strike that halts and possibly reverses organ damage is crucial. The development of agents that facilitate the clearance of pathological fibrillar deposits, therefore reducing the frailty of patients, is the needed supplement to plasma cell-directed therapy. Monoclonal antibodies provide therapy against malignant plasma cells (daratumumab, isatuximab, elotuzumab) but they are also able to target and eliminate the amyloid from organs (NEOD001, CAEL-101, dezamizumab). From the plasma cell-directed group, daratumumab in monotherapy has proved to be extremely efficient in relapsed AL amyloidosis, exceeding its results in multiple myeloma. Compared to other agents, monoclonal antibodies possess the advantage of high selectivity and low toxicity and could potentially become future game-changers in this field. Co-targetting of the plasma cell clone and amyloid deposits shall together be translated in the revolutionary improved outcome of potentially curable AL amyloidosis.

Abstract
PURPOSE At present, a diverse array of treatment regimens are available for systemic amyloid light-chain (AL) amyloidosis. Both cyclophosphamide + thalidomide + dexamethasone (CTD) and melphalan + dexamethasone (MD) regimens have been recommended as first-line therapies, but no detailed comparative studies of the two have been performed. This study is the first to compare the efficacy and tolerability of the CTD and MD regimens in the treatment of AL amyloidosis. METHODS We retrospectively reviewed data from consecutive patients with AL amyloidosis who were treated with MD or CTD as the initial regimen between June 2012 and January 2018. FINDINGS In the final analysis, 38 patients received CTD, and 30 received MD. There were no significant differences in baseline characteristics, including age, sex, renal function, involved organs, level of free light chains, and Mayo Clinic amyloidosis prognostic staging. The overall hematologic response rates in the CTD and MD groups were 69.0% versus 68.0%, respectively (P = 0.94), including a complete response in 27.6% versus 8.0% (P = 0.14). Neither group reached the estimated median overall survival, and the difference between the 2 groups was not significant (P = 0.17). The median progression-free survival times were 36 versus 14 months (P = 0.24) in the CTD and MD groups, respectively. The CTD group achieved a numerically but not statistically higher prevalence of kidney response (52.9% vs 37.0%; P = 0.22). The most common adverse events in the 2 treatment groups were fatigue (48.5% vs 21.7%; P = 0.04) and constipation, anemia, nausea/vomiting, neutropenia, and syncope (all, P = NS). Deaths occurred in 6 patients in the CTD group and 9 patients in the MD group; none were considered by the investigators as related to the study treatments. There were no other serious adverse events observed in our study. IMPLICATIONS The CTD regimen may not be inferior to standard oral MD in terms of overall hematologic response and overall survival. Although this study was of retrospective and negative-control design with some additional limitations, it may provide a therapeutic option for use in developing countries where patients cannot afford bortezomib or melphalan.

Abstract
The treatment of cancer, especially of various types of solid tumors, has been revolutionized by the blockade of the PD-1/PD-L1 pathway by immune checkpoint inhibitors. Their success amongst hematologic malignancies, however, has been limited so far to the treatment of classic Hodgkin's lymphoma, which portrays a typical overexpression of PD-1 ligands (PD-L1, PD-L2) as a consequence of changes in chromosome 9p24.1. Their current application in multiple myeloma (MM) is rather uncertain, as discordant results have been reported by distinct research groups concerning especially the expression of PD-1/PD-L1 molecules on malignant plasma cells or on the responsible immune effector cell populations, respectively. In MM it seems that an approach based on combination treatment might be appropriate as unsatisfactory results have been yielded by monotherapy with PD-1/PD-L1 inhibitors. Immunomodulatory drugs, which are the current cornerstone of MM treatment, are the most logical partners as they possess many possibly synergistic effects. Nevertheless, the initially optimistic results have become disappointing due to the excessive and unpredictable toxicity of the combination of pembrolizumab with lenalidomide or pomalidomide. The FDA has suspended or put on hold several phase 3 trials in relapsed as well as in newly diagnosed myeloma patients. There are also other potentially synergistic and promising combinations, such as the anti-CD38 monoclonal antibody daratumumab, irradiation, etc. Not only the effective partner but also the correct timing of the initiation of the PD-1/PD-L1 inhibitors treatment seems to be of utmost importance. These strategies are currently being examined in various stages of myeloma such as during consolidation post autologous stem cell transplantation, targeting minimal residual disease or even in high risk smoldering myeloma.

Abstract
Pomalidomide is a next-generation immunomodulatory agent with activity in relapsed light chain (AL) amyloidosis, but real world outcomes are lacking. We report the experience of the UK National Amyloidosis Centre. All patients with AL amyloidosis treated with pomalidomide between 2009 and 2017 were included. Data was collected on treatment toxicity and clonal response. Survival was calculated by the Kaplan-Meier method and outcomes reported on an intent-to-treat (ITT) basis. A total of 29 patients treated with pomalidomide were identified. Haematological responses at 3 months were: complete response (CR) nil, very good partial response (VGPR) 10 (35%), partial response (PR) 9 (31%), stable or progressive disease 7 (24%), unevaluable 3 (10%). On an ITT basis (n = 28), responses at 6 months were: CR- nil, VGPR-11 (39%), PR-2 (7%) and the remaining patients were non-responders 15 (53%). Median overall survival was 27 months (95% confidence interval 15·7-38·1 months). Median progression free survival (PFS) was 15 months (95% confidence interval 6·24-23·77). In conclusion, pomalidomide has activity in patients with relapsed AL amyloidosis. Responses are rapid and early responses may be predictive of a sustained overall response. Deep responses (VGPR or better) are seen in only a third of all patients and combination therapy needs to be explored.

Abstract
Treatment for acute myeloid leukemia (AML) remains suboptimal and many patients remain refractory or relapse upon standard chemotherapy based on nucleoside analogs plus anthracyclines. The crosstalk between AML cells and the BM stroma is a major mechanism underlying therapy resistance in AML. Lenalidomide and pomalidomide, a new generation immunomodulatory drugs (IMiDs), possess pleiotropic anti-leukemic properties including potent immune-modulating effects and are commonly used in hematological malignances associated with intrinsic dysfunctional BM such as myelodysplastic syndromes and multiple myeloma. Whether IMiDs may improve the efficacy of current standard treatment in AML remains understudied. Here, we have exploited in vitro and in vivo preclinical AML models to analyze whether IMiDs potentiate the efficacy of AraC/Idarubicin-based standard AML chemotherapy by interfering with the BM stroma-mediated chemoresistance. We report that IMiDs do not exert cytotoxic effects on either non-del5q/5q- AML cells nor BM-MSCs, but they enhance the immunomodulatory properties of BM-MSCs. When combined with AraC/Idarubicin, IMiDs fail to circumvent BM stroma-mediated resistance of non-del5q/5q- AML cells in vitro and in vivo but induce robust extramedullary mobilization of AML cells. When administered as a single agent, lenalidomide specifically mobilizes non-del5q/5q- AML cells, but not healthy CD34+ cells, to peripheral blood (PB) through specific downregulation of CXCR4 in AML blasts. Global gene expression profiling supports a migratory/mobilization gene signature in lenalidomide-treated non-del5q/5q- AML blasts but not in CD34+ cells. Collectively, IMiDs mobilize non-del5q/5q- AML blasts to PB through CXCR4 downregulation, but fail to potentiate AraC/Idarubicin activity in preclinical models of non-del5q/5q- AML.

Abstract
Multiparameter flow cytometry (MFC) has become standard in the management of patients with plasma cell (PC) dyscrasias, and could be considered mandatory in specific areas of routine clinical practice. It plays a significant role during the differential diagnostic work-up because of its fast and conclusive readout of PC clonality, and simultaneously provides prognostic information in most monoclonal gammopathies. Recent advances in the treatment and outcomes of multiple myeloma led to the implementation of new response criteria, including minimal residual disease (MRD) status as one of the most relevant clinical endpoints with the potential to act as surrogate for survival. Recent technical progress led to the development of next-generation flow (NGF) cytometry that represents a validated, highly sensitive, cost-effective and widely available technique for standardized MRD evaluation, which also could be used for the detection of circulating tumor cells. Here we review current applications of MFC and NGF in most PC disorders including the less frequent solitary plasmocytoma, light-chain amyloidosis or Waldenström macroglobulinemia.

Abstract
INTRODUCTION The field of systemic amyloidosis is experiencing major advances in diagnostic and prognostic methods coupled with a growing availability in treatment options. AREAS COVERED Treatment of AL amyloidosis traditionally targeted the clonal plasma cells, in order to block further production of amyloidogenic light chains. Currently, a research focus is placed on targeting the already formed amyloid deposits using monoclonal antibodies against epitopes on such deposits. Encouraging results were obtained from the three investigated antibodies: NEOD001, 11-1F4 and anti-SAP, but further validation is required before these antibodies can be commercialized. In this paper, we review the current active clinical research in AL amyloidosis, which includes the monoclonal antibodies targeting amyloid deposits, daratumumab, Venetoclax, doxycycline, green tea, pomalidomide, carfilzomib and ixazomib. EXPERT OPINION Monoclonal antibodies, targeting either the amyloid deposits or the plasma cell compartment will likely be integrated into routine treatment practice given their encouraging results and minimal toxicity in the fragile population of AL amyloidosis. Other therapeutic options hold promise to the field as well, but toxicity will likely challenge their routine use. Early recognition remains the best option for outcome enhancement.

Differential recruitment efficacy of patient-derived amyloidogenic and myeloma light chain proteins by synthetic fibrils-A metric for predicting amyloid propensity. PLoS One 2017; 12:e0174152. [PMID: 28350808 PMCID: PMC5369765 DOI: 10.1371/journal.pone.0174152] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/30/2016] [Accepted: 03/03/2017] [Indexed: 11/19/2022] Open
Abstract
BACKGROUND Monoclonal free light chain (LC) proteins are present in the circulation of patients with immunoproliferative disorders such as light chain (AL) amyloidosis and multiple myeloma (MM). Light chain-associated amyloid is a complex pathology composed of proteinaceous fibrils and extracellular matrix proteins found in all patients with AL and in ~10-30% of patients who presented with MM. Amyloid deposits systemically in multiple organs and tissues leading to dysfunction and ultimately death. The overall survival of patients with amyloidosis is worse than for those with early stage MM. METHODS AND FINDINGS We have developed a sensitive binding assay quantifying the recruitment of full length, patient-derived LC proteins by synthetic amyloid fibrils, as a method for studying their amyloidogenic potential. In a survey of eight urinary LC, both AL and MM-associated proteins were recruited by synthetic amyloid fibrils; however, AL-associated LC bound significantly more efficiently (p < 0.05) than did MM LCs. The LC proteins used in this study were isolated from urine and presumed to represent a surrogate of serum free light chains. CONCLUSION The binding of LC to synthetic fibrils in this assay accurately differentiated LC with amyloidogenic propensity from MM LC that were not associated with clinical amyloid disease. Notably, the LC from a MM patient who subsequently developed amyloid behaved as an AL-associated protein in the assay, indicating the possibility for identifying MM patients at risk for developing amyloidosis based on the light chain recruitment efficacy. With this information, at risk patients can be monitored more closely for the development of amyloidosis, allowing timely administration of novel, amyloid-directed immunotherapies-this approach may improve the prognosis for these patients.

Abstract
Thalidomide is an immunomodulatory drug (IMiD) with proven therapeutic action in several autoimmune/inflammatory diseases; however, its inherent high toxicity has led to the development of more powerful and safer thalidomide analogs, including lenalidomide and pomalidomide. These are new generation IMiDs that exhibit direct antitumor activity as well as anti-inflammatory/immunomodulatory properties, and are FDA-approved for the treatment of several hematological malignances. Here we investigated the potential therapeutic effects of lenalidomide and pomalidomide in several experimental murine models of autoimmune/inflammatory diseases: 2,4,6-trinitrobenzene sulfonic acid- and dextran sulfate sodium-induced inflammatory bowel disease and type II collagen-induced arthritis. Lenalidomide displayed a strong therapeutic effect in all these models of autoimmune/inflammatory diseases, while the effect of pomalidomide was less pronounced. In vitro experiments confirmed the immunosuppressive effect of both IMiDs on the proliferative response of stimulated human lymphocytes and on the balance of secreted cytokines toward an anti-inflammatory profile. We conclude that lenalidomide may offer a therapeutic opportunity against autoimmune/inflammatory diseases.

Abstract
Multiple myeloma (MM) and primary systemic light chain amyloidosis (AL) are both chronic plasma cell dyscrasias with different clinical expression but limited treatment options for relapsed refractory disease. We report the effect of the addition of clarithromycin on 31 MM and 17 AL with relapsed or refractory disease who had an insufficient response or disease progression while on an IMiD based therapy. In this high risk population, hematological response was reported in 48% of MM patients and 94% of AL patients. Responses were reported early in both groups (median 35 days) and were more sustained in AL patients. Adverse events were common and included mostly grade 1-2 fatigue, infections and abdominal discomfort. Cytopenias were common and cardiac complications were rare in both MM and AL patients. Clarithromycin-IMiD combination therapy appears to be both effective and safe in progressive MM and primarily in AL patients, although a prospective clinical trial is warranted to validate these results.

Abstract
Proteasome inhibitors are the backbone in the treatment of multiple myeloma with 3 of its representatives (bortezomib, carfilzomib, and ixazomib) having already been approved. There is a different situation altogether in the treatment of amyloid light chain (AL) amyloidosis where owing to the rarity of this entity neither of these drugs has currently gained approval. Amyloid light chain plasma cells are possibly more vulnerable to bortezomib than myeloma plasmocytes because of a slightly distinct mechanism of action, which is described in depth in this manuscript. Bortezomib is highly active and rapidly effective as a single agent and even more potent in combination with dexamethasone and alkylators. Bortezomib-based regimens have become a standard part of the initial treatment of AL amyloidosis in the majority of centers. We have reviewed all available data on bortezomib in various combinations and settings. Carfilzomib seems to be effective but also toxic in these fragile patients with a high rate of cardiac events. Oral ixazomib has shown a surprisingly high efficacy with manageable toxicity and has received the Food and Drug Administration Breakthrough Therapy designation in 2014 for relapsed AL amyloidosis patients. In this review we have comprehensively described the current available knowledge of these 3 proteasome inhibitors and their use in AL amyloidosis.
