Abstract
BACKGROUND In the present study, it was investigated whether autonomic dysfunction could predict prognosis in light-chain (AL) amyloidosis patients. PATIENTS AND METHODS Seventy-two patients with biopsy-proven AL amyloidosis were included and underwent an autonomic function test (AFT) between January 2016 and June 2019. Autonomic failure was evaluated using the Composite Autonomic Severity Score (CASS). Survival curves and the three-year overall survival (OS) rate were estimated using the Kaplan-Meier curve, and the Cox proportional hazards regression method was used to evaluate the variables that influenced survival. RESULTS Autonomic dysfunction was observed in 69 (96%) patients with AL amyloidosis, and the three-year OS rate was 67%. Generalised autonomic failure (GAF) was observed in 31 (43%) patients. In the Kaplan-Meier curve, the three-year OS rates in patients with sudomotor dysfunction or GAF were lower than that in control patients (35 vs. 84%, and 33 vs. 81%, respectively). In Cox proportional hazards regression model, female, bone marrow plasma cell percentage, left ventricular systolic dysfunction, and GAF were significant independent variables associated with survival. CONCLUSION The results of this study indicate that GAF on the AFT is an independent adverse prognostic factor for survival in AL amyloidosis patients.

Abstract
DISEASE OVERVIEW Immunoglobulin light chain amyloidosis is a clonal, nonproliferative plasma cell disorder in which fragments of immunoglobulin light or heavy chain are deposited in tissues. Clinical features depend on organs involved but can include heart failure with preserved ejection fraction, nephrotic syndrome, hepatic dysfunction, peripheral/autonomic neuropathy, and "atypical smoldering multiple myeloma or monoclonal gammopathy of undetermined significance (MGUS)." DIAGNOSIS Tissue biopsy stained with Congo red demonstrating amyloid deposits with apple-green birefringence is required for the diagnosis of AL amyloidosis. Invasive organ biopsy is not required in 85% of patients. Verification that amyloid is composed of immunoglobulin light chains is mandatory. The gold standard is laser capture mass spectroscopy. PROGNOSIS N-terminal pro-brain natriuretic peptide (NT-proBNP or BNP), serum troponin T (or I), and difference between involved and uninvolved immunoglobulin free light chain values are used to classify patients into four groups of similar size; median survivals are 73, 35, 15, and 5 months. THERAPY All patients with a systemic amyloid syndrome require therapy to prevent deposition of amyloid in other organs and prevent progressive organ failure. Current first-line therapy with the best outcome is daratumumab, bortezomib, cyclophosphamide, and dexamethasone. The goal of therapy is a complete response (CR). In patients failing to achieve this depth of response options for consolidation include pomalidomide, stem cell transplantation, venetoclax, and bendamustine. FUTURE CHALLENGES Delayed diagnosis remains a major obstacle to initiating effective therapy prior to the development of end-stage organ failure. Trials of antibodies to catabolize deposited fibrils are underway.

Abstract
Introduction: Treatment of amyloid light-chain (AL) amyloidosis, a rare disease with a <5-year lifespan, remains challenging. This systematic literature review (SLR) aimed to evaluate the current evidence base in AL amyloidosis. Methods: Literature searches on clinical, health-related quality of life, economic and resource use evidence were conducted using the Embase, MEDLINE and Cochrane databases as well as gray literature. Results: This SLR yielded 84 unique studies from: five randomized controlled trials; 54 observational studies; 12 health-related quality of life studies, none with utility values; no economic evaluation studies; and 16 resource use studies, none with indirect costs. Conclusion: This SLR highlights a paucity of published literature relating to randomized controlled trials, utility values, economic evaluations and indirect costs in AL amyloidosis.

Abstract
Background Treatment protocols for light chain (AL) amyloidosis have been derived from myeloma treatment. Bortezomib is a key drug used for the treatment of myeloma and AL amyloidosis. We retrospectively investigated the efficacy and toxicity of bortezomib- based chemotherapy in patients with newly diagnosed AL amyloidosis. Methods We reviewed the outcomes of newly diagnosed autologous stem cell transplantation (auto-SCT)-ineligible AL amyloidosis patients who received bortezomib-based chemotherapy at a referral center between 2011 and 2017. Results Of 63 patients who received bortezomib-based chemotherapy, 32 were male, and the median age was 66 years (range, 42‒82 yr). The hematologic overall response rate (ORR) was 65.1%, and the chemotherapy regimen with the best hematologic response was VMP (75.7%, 28/37). Sixty patients had significant organ (heart or kidney) involvement; 28.3% of patients (N=17) had major organ responses after chemotherapy. With a median follow- up of 34 months, there was no significant difference in progression-free survival (P=0.49) or overall survival (P =0.67) according to regimen. Most hematologic and non-hematologic problems were manageable. Conclusion Various chemotherapy combinations based on bortezomib are currently employed in the clinical setting, but no difference was found in terms of efficacy or toxicity.

Venetoclax induces deep hematologic remissions in t(11;14) relapsed/refractory AL amyloidosis. Blood Cancer J 2021; 11:10. [PMID: 33431806 PMCID: PMC7801694 DOI: 10.1038/s41408-020-00397-w] [Citation(s) in RCA: 35] [Impact Index Per Article: 11.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/20/2020] [Revised: 11/14/2020] [Accepted: 11/24/2020] [Indexed: 12/12/2022] Open
Abstract
Venetoclax is efficacious in relapsed/refractory t(11;14) multiple myeloma, thus warranting investigation in light-chain amyloidosis (AL). This retrospective cohort includes 43 patients with previously treated AL, from 14 centers in the US and Europe. Thirty-one patients harbored t(11;14), 11 did not, and one t(11;14) status was unknown. Patients received a venetoclax-containing regimen for at least one 21- or 28-day cycle; the median prior treatments was three. The hematologic response rate for all patients was 68%; 63% achieved VGPR/CR. t(11;14) patients had higher hematologic response (81% vs. 40%) and higher VGPR/CR rate (78% vs. 30%, odds ratio: 0.12, 95% CI 0.02–0.62) than non-t(11;14) patients. For the unsegregated cohort, median progression-free survival (PFS) was 31.0 months and median OS was not reached (NR). For t(11;14), median PFS was NR and for non-t(11;14) median PFS was 6.7 months (HR: 0.14, 95% CI 0.04–0.53). Multivariate analysis incorporating age, sex, prior lines of therapy, and disease stage suggested a risk reduction for progression or death in t(11;14) patients. Median OS was NR for either subgroup. The organ response rate was 38%; most responders harbored t(11;14). Grade 3 or higher adverse events occurred in 19% with 7% due to infections. These promising results require confirmation in a randomized clinical trial.

Abstract
Significant practice-changing developments have occurred in the care of heart transplantation candidates and recipients over the past decade. This Canadian Cardiovascular Society/Canadian Cardiac Transplant Network Position Statement provides evidence-based, expert panel recommendations with values and preferences, and practical tips on: (1) patient selection criteria; (2) selected patient populations; and (3) post transplantation surveillance. The recommendations were developed through systematic review of the literature and using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) system. The evolving areas of importance addressed include transplant recipient age, frailty assessment, pulmonary hypertension evaluation, cannabis use, combined heart and other solid organ transplantation, adult congenital heart disease, cardiac amyloidosis, high sensitization, and post-transplantation management of antibodies to human leukocyte antigen, rejection, cardiac allograft vasculopathy, and long-term noncardiac care. Attention is also given to Canadian-specific management strategies including the prioritization of highly sensitized transplant candidates (status 4S) and heart organ allocation algorithms. The focus topics in this position statement highlight the increased complexity of patients who undergo evaluation for heart transplantation as well as improved patient selection, and advances in post-transplantation management and surveillance that have led to better long-term outcomes for heart transplant recipients.

Abstract
Immunoglobulin light-chain (AL) amyloidosis is a clonal plasma cell disorder characterised by production and deposition of misfolded monoclonal light chains in vital organs with potential to cause irreversible organ damage. The treatment of AL amyloidosis has evolved along the lines of multiple myeloma (MM) owing to clonal plasma cells being at the root of both disease processes. Treatment with melphalan and autologous haematopoietic cell transplantation, as well as proteasome inhibitors and immunomodulatory agents, are the standard of care for AL amyloidosis. While these treatment modalities are highly effective against the neoplastic plasma cells, patients often relapse and those with advanced disease may be unable to tolerate these treatments due to side-effects. Immunotherapy with monoclonal antibodies, bispecific antibodies, antibody-drug conjugates and chimeric antigen receptor T cells have revolutionised the treatment armamentarium for MM. These novel immunotherapy agents are in the early phases of evaluation and clinical development for patients with AL amyloidosis. The present review aims to discuss the role of novel immunotherapies currently in development and their potential for use in the treatment of AL amyloidosis.

Abstract
Background: Patients with amyloid light-chain (AL) amyloidosis who have advanced cardiac damage are at risk of premature mortality. Currently, bortezomib is the mainstay in the treatment of AL amyloidosis, but the benefits of bortezomib in patients with ultra-high-risk (2004 Mayo stage IIIb or 2012 Mayo stage IV) AL amyloidosis have not been proved definitively. Methods: We performed a retrospective analysis of patients newly diagnosed with ultra-high-risk AL amyloidosis who received a bortezomib-based regimen or supportive treatment. We aimed to establish the effects of bortezomib on early mortality and long-term outcomes in this high-risk population. Results: Patients receiving bortezomib-containing chemotherapy (n = 62) and patients receiving no chemotherapy (n = 24) were included. Median overall survival (OS) was 30 months in the bortezomib group and 2 months in the control group (p < .001), and median progression-free survival (PFS) was 15.8 months (bortezomib) and 2 months (control; p < .001). The early-death rate (within 6 months of treatment) was 32.3% (bortezomib) and 66.7% (control; p < .001). In a landmark analysis assessing outcomes in patients surviving beyond 6 months, the 2-year OS and PFS in the bortezomib group were 77.3% and 65.8%, respectively. Conclusions: Bortezomib-based regimens can help to reduce early mortality and improve long-term survival in patients with ultra-high-risk AL amyloidosis.

Abstract
Autologous stem cell transplantation (ASCT) has been used as treatment for immunoglobulin light-chain (AL) amyloidosis for over two decades with improving outcomes; however, the majority of patients are not candidates for this therapy at diagnosis. Novel agents such as immunomodulatory drugs, proteasome inhibitors, and immunotherapy with monoclonal antibodies targeting CD38 have been adopted from the multiple myeloma spheres with encouraging results. Herein, we discuss the role of daratumumab, a monoclonal antibody to CD38, in the treatment of AL amyloidosis. We focus on its mechanism of action, tolerability, and the current published data on its use in AL amyloidosis. Early data from phase I and phase II studies show that daratumumab is tolerated well in this population and induces rapid and deep responses. Phase III trials are currently accruing and we envision daratumumab becoming a key component in the treatment of AL amyloidosis in the future.

Abstract
DISEASE OVERVIEW Immunoglobulin light chain amyloidosis is a clonal, nonproliferative plasma cell disorder in which fragments of immunoglobulin light or heavy chain are deposited in tissues. Clinical features depend on organs involved but can include restrictive cardiomyopathy, nephrotic syndrome, hepatic dysfunction, peripheral/autonomic neuropathy, and "atypical multiple myeloma." DIAGNOSIS Tissue biopsy stained with Congo red demonstrating amyloid deposits with apple-green birefringence is required for diagnosis. Invasive organ biopsy is not required because amyloid deposits can be found in bone marrow, salivary gland, or subcutaneous fat aspirate in 85% of patients. Verification that amyloid is composed of immunoglobulin light chains is mandatory. The gold standard is laser capture mass spectroscopy. PROGNOSIS N-terminal pro-brain natriuretic peptide (NT-proBNP), serum troponin T, and difference between involved and uninvolved immunoglobulin free light chain values are used to classify patients into four groups of similar size; median survivals are 94.1, 40.3, 14.0, and 5.8 months. THERAPY All patients with a systemic amyloid syndrome require therapy to prevent deposition of amyloid in other organs and prevent progressive organ failure. Stem cell transplant (SCT) is preferred, but only 20% of patients are eligible. Requirements for safe SCT include systolic blood pressure >90 mm Hg, troponin T < 0.06 ng/mL, age < 70 years, and serum creatinine ≤1.7 mg/dL. Nontransplant candidates can be offered melphalan-dexamethasone or cyclophosphamide-bortezomib-dexamethasone. Daratumumab appears to be highly active in AL amyloidosis. Antibodies designed to dissolve existing amyloid deposits are under study. FUTURE CHALLENGES Delayed diagnosis remains a major obstacle to initiating effective therapy. EDUCATIONAL OBJECTIVES Upon completion of this educational activity, participants will be better able to: Master recognition of clinical presentations that should raise suspicion of amyloidosis. Understand simple techniques for confirming the diagnosis and providing material to classify the protein subunit. Recognize that a tissue diagnosis of amyloidosis does not indicate whether the amyloid is systemic or of immunoglobulin light chain origin. Understand the roles of the newly introduced chemotherapeutic and investigational antibody regimens for the therapy of light chain amyloidosis.

Abstract
Purpose Autologous stem-cell transplantation (ASCT) has been used in patients with immunoglobulin light chain (AL) amyloidosis for more than two decades. Early experience raised concerns regarding safety with high early-mortality rates. Patients and Methods We report 20 years of experience with ASCT for AL amyloidosis at the Mayo Clinic Rochester. In all, 672 consecutive patients receiving ASCT for AL amyloidosis were divided into three cohorts on the basis of date of transplantation (cohort 1, 1996-2002 [n = 124]; cohort 2, 2003-2009 [n = 302]; and cohort 3, 2010-2016 [n = 246]). Results The median age for the entire cohort was 59 years, with patients in cohort 3 being slightly older than those in the other two cohorts (60 v 58 v 54 years for cohorts 3, 2, and 1, respectively; P < .001). Fewer patients in cohort 3 had more than two organs involved (9% v 18% v 19% for cohorts 3, 2, and 1, respectively; P < .001). More patients received pretransplantation therapy in cohort 3 compared with earlier time periods (49% v 38% v 42% for cohorts 3, 2, and 1, respectively; P = .02). Hematologic response was higher in cohort 3 (84% v 79% v 69% for cohorts 3, 2, and 1, respectively; P = .002). Median overall survival for the entire cohort was 122 months and improved over time (not reached v 120 months v 75 months for cohorts 3, 2, and 1, respectively; P < .001). Treatment-related mortality declined over time (2.4% v 8.6% v 14.5% for cohorts 3, 2, and 1, respectively; P < .001). On multivariable analysis, conditioning dose, Mayo stage 2012, and hematologic response were independent predictors of survival. Conclusion ASCT is a highly effective therapy for AL amyloidosis. The improved survival and markedly reduced treatment-related mortality in eligible patients indicate that this will remain an important first-line option even in the era of treatment approaches that use novel agents.

Abstract
Clinically applicable platforms revealing actionable genomic alterations may improve the treatment efficacy of myeloma patients. In this pilot study, we used a high depth targeted sequencing panel containing 83 anti-cancer drug target genes to sequence genomic DNAs extracted from bone marrow aspirates of 23 patients with myeloma and 12 patients with amyloid light-chain (AL) amyloidosis. Mutation analysis revealed NRAS as the most commonly mutated gene (30%, 7/23) in myeloma patients followed by KRAS (26%, 6/23) and BRAF (22%, 5/23). However, no significant mutations were found in the 12 patients with AL amyloidosis. Notably, 6 of the 23 myeloma patients showed multi-site and/or multi-gene mutations in NRAS, KRAS, or BRAF, indicating compound aberrations in the Mitogen activated protein kinase (MAPK) pathway. Gene panel sequencing also revealed cytogenetic abnormalities associated with prognosis in myeloma patients. In conclusion, our pilot study suggests that targeted gene sequencing may have an important prognostic value for myeloma patients for the identification of actionable genomic alterations and cytogenetic aberrations.

Abstract
DISEASE OVERVIEW Immunoglobulin light chain amyloidosis is a clonal, nonproliferative plasma cell disorder in which fragments of immunoglobulin light chain are deposited in tissues. Clinical features depend on organs involved but can include restrictive cardiomyopathy, nephrotic syndrome, hepatic failure, peripheral/autonomic neuropathy, and atypical multiple myeloma. DIAGNOSIS Tissue biopsy stained with Congo red demonstrating amyloid deposits with applegreen birefringence is required for diagnosis. Invasive organ biopsy is not required because amyloid deposits can be found in bone marrow biopsy or subcutaneous fat aspirate in 85% of patients. Verification that amyloid is composed of immunoglobulin light chains is mandatory. PROGNOSIS N-terminal pro-brain natriuretic peptide (NTproBNP), serum troponin T, and difference between involved and uninvolved immunoglobulin free light chain values are used to classify patients into four groups of similar size; median survivals are 94.1, 40.3, 14.0, and 5.8 months. THERAPY All patients with a systemic amyloid syndrome require therapy to prevent deposition of amyloid in other organs and prevent progressive organ failure of involved sites. Stem cell transplant (SCT) is preferred, but only 20% of patients are eligible. Requirements for safe SCT include systolic blood pressure >90 mmHg, troponin T <0.06 ng mL21, age <70 years, and serum creatinine 1.7 mg dL21. Nontransplant candidates can be offered melphalan-dexamethasone or cyclophosphamide-bortezomib-dexamethasone. Other combinations of chemotherapy with agents such as cyclophosphamide-thalidomide (or lenalidomide)-dexamethasone, bortezomib-dexamethasone, and melphalan-prednisone-lenalidomide have documented activity. Antibodies designed to dissolve existing amyloid deposits are under study for previously treated and untreated patients. Late diagnosis remains a major obstacle to initiating effective therapy. Am.

Abstract
Immunoglobulin light chain amyloidosis (AL) is a rare, complex disease caused by misfolded free light chains produced by a usually small, indolent plasma cell clone. Effective treatments exist that can alter the natural history, provided that they are started before irreversible organ damage has occurred. The cornerstones of the management of AL amyloidosis are early diagnosis, accurate typing, appropriate risk-adapted therapy, tight follow-up, and effective supportive treatment. The suppression of the amyloidogenic light chains using the cardiac biomarkers as guide to choose chemotherapy is still the mainstay of therapy. There are exciting possibilities ahead, including the study of oral proteasome inhibitors, antibodies directed at plasma cell clone, and finally antibodies attacking the amyloid deposits are entering the clinic, offering unprecedented opportunities for radically improving the care of this disease.

Abstract
UNLABELLED We performed a phase 1 study to evaluate the safety and feasibility of bortezomib (BOR) with melphalan and dexamethasone (BMD) in patients with light chain amyloidosis (AL) without severe cardiac failure. Patients received BOR on a twice-weekly schedule (days 1, 4, 8, and 11 of 28-day treatment cycles) at planned doses of 1.0 (dose level 1) and 1.3 (dose level 2) mg/m(2) in combination with melphalan 8 mg/m(2) on days 1-4 and dexamethasone 20 mg on days 1, 2, 4, 5, 8, 9, 11, and 12. Dose-limiting toxicity (DLT) was evaluated at the end of cycle one, and treatment was continued for four cycles. Six patients were enrolled at dose level 1, and one showed DLT (grade 3: herpes zoster). Further 3 patients were enrolled at dose level 2, and none experienced DLT. Thus, the maximum tolerated dose was defined as BOR doses of 1.3 mg/m(2) for the twice-weekly schedule. A total of 32 cycles of BMD therapy were given, and the most common hematologic toxicity was thrombocytopenia (47%). Peripheral neuropathy was the most common non-hematologic toxicity (16%). We demonstrated that BMD is safe and tolerable for Japanese AL patients without severe cardiac damage. CLINICAL TRIAL REGISTRATION UMIN000006604.

Abstract
Immunoglobulin light chain amyloidosis (AL amyloidosis) has an incidence of approximately 1 case per 100,000 person-years in Western countries. The rarity of the condition not only poses a challenge for making a prompt diagnosis but also makes evidenced decision making about treatment even more challenging. Physicians caring for patients with AL amyloidosis have been borrowing and customizing the therapies used for patients with multiple myeloma with varying degrees of success. One of the biggest failings in the science of the treatment of AL amyloidosis is the paucity of prospective trials, especially phase 3 trials. Herein, we present an extensive review of the literature with an aim of making recommendations in the context of the best evidence and expert opinion.
