The investigators plan to establish a dedicated network of Italian Hematologic Departments interconnected with the Amyloidosis Research and Treatment Center in Pavia to: 1. Implement a biomarker-based screening strategy to promote early diagnosis of AL amyloidosis among at-risk patients, including patients with monoclonal gammopathy of undetermined significance, MGUS, and altered free light chain ratio (aFLCR), and patients with smoldering multiple myeloma (SMM) 2. Expedite and facilitate patients' referral and their enrollment in ongoing pre-clinical/clinical studies, also to reflect a broader spectrum of the real-world population of patients with AL amyloidosis in Italy; 3. Investigate the clinical utility of novel diagnostic technologies, including light chain sequencing and N-glycosylation analysis
NCT04512235
AL (or light chain) amyloidosis begins in the bone marrow where abnormal proteins misfold and create free light chains that cannot be broken down. These free light chains bind together to form amyloid fibrils that build up in the extracellular space of organs, affecting the kidneys, heart, liver, spleen, nervous system and digestive tract. The primary purpose of this study is to determine whether CAEL-101, a monoclonal antibody that removes AL amyloid deposits from tissues and organs, improves overall survival, reduces cardiovascular related hospitalizations and it is safe and well tolerated in patients with stage IIIa AL amyloidosis.

NCT06192979
Achievement of complete hematologic response (CHR) is vital for systemic AL amyloidosis. Currently, the CHR rate of daratumumab, bortezomib, and dexamethasone (DBD) is close to 60%. Considering that Bcl-2 inhibitor is effective for AL amyloidosis with t(11; 14) and the median hematologic onset time of DBD is 7 days. We design a a prospective study on AL amyloidosis with t(11; 14). All patients receive DBD at the beginning. Patient will receive DBD for at least 6 cycles if achieve rapid hematologic response at day 7, while other patients will receive daratumumab, venetoclax and dexamethasone.
NCT06569147
This study will evaluate the safety, tolerability and efficacy of elranatamab in patients with relapsed or refractory AL amyloidosis.
NCT04754945
This phase I trial studies the side effects of isatuximab and to see how well it works in treating patients with high risk immunoglobulin light chain amyloidosis (AL amyloidosis). Isatuximab is a monoclonal antibody that may interfere with the ability of tumor cells to grow and spread.
NCT07250269
This is a Phase 1b open-label, multicenter, non-randomized study of GC012F, a CD19/BCMA dual CAR T cell therapy, in adult participants with relapsed/refractory AL amyloidosis.
NCT03315026
Autologous stem cell transplant is beneficial to patients who are diagnosed with multiple myeloma or systemic amyloidosis. However, undesired symptoms such as weakness, fatigue, nausea, pain and sleep disturbance after transplant can contribute to complications and increase the how long the patient is in the hospital, especially in patients age 60-75. Research has shown that the development and the intensity of these symptoms are closely associated with an increase in a protein called a cytokine which is involved in the inflammatory response in the human body. One of the cytokines is called Interleukin-6 or IL-6.Therefore, this study will investigate if blocking IL-6 with an agent called siltuximab, administered before and after transplant, will decrease the symptom burden after transplant to improve quality of life and recovery in the immediate post-transplant period.
NCT06022939
This phase III trial compares the effect of adding a stem cell transplant with melphalan after completing chemotherapy with daratumumab, cyclophosphamide, bortezomib and dexamethasone (Dara-VCD) versus chemotherapy with Dara-VCD alone for treating patients with newly diagnosed amyloid light chain (AL) amyloidosis. Melphalan is a chemotherapy given prior to a stem cell transplant. Giving chemotherapy before a peripheral blood stem cell transplant helps kill cancer cells in the body and helps make room in the patient's bone marrow for new blood-forming cells (stem cells) to grow. The stem cells are then returned to the patients to replace the blood forming cells that were destroyed by the chemotherapy. Daratumumab is in a class of medications called monoclonal antibodies. It binds to a protein called CD38, which is found on some types of immune cells and cancer cells, including myeloma cells. Daratumumab may block CD38 and help the immune system kill cancer cells. Chemotherapy drugs, such as cyclophosphamide and bortezomib, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Dexamethasone is in a class of medications called corticosteroids. It is used to lower the body's immune response to help stop the growth of cancer cells. Giving a stem cell transplant with melphalan after Dara-VCD may kill more cancer cells in patients with newly diagnosed AL amyloidosis.
NCT07103863
1. Goal of the Study: The goal of this prospective observational study is to develop and validate a novel, non-invasive method for predicting the prognosis of patients with light-chain cardiac amyloidosis (AL-CA). This method integrates advanced multi-modal imaging techniques and artificial intelligence (radiomics) to provide early and accurate assessment of treatment response and survival outcomes. 2. Main Question: Can a multi-modal radiomics model, based on the fusion of \[¹⁸F\]FAPI PET/CT (assessing fibroblast activation) and 3D Cardiac MRI (CMR) (assessing structural damage) imaging data, accurately predict 12-month all-cause mortality and dynamically track disease progression in patients with AL-CA receiving standard care? 3. Participants: Population: Patients diagnosed with AL-CA (confirmed by endomyocardial biopsy or extracardiac biopsy plus specific cardiac criteria: NT-proBNP \>332 pg/mL, mean left ventricular wall thickness \>12 mm, excluding hypertension/other causes). Setting: Single-center study at Beijing Anzhen Hospital, Capital Medical University. Number: 49 patients (calculated sample size accounting for dropouts). Key Criteria: Inclusion: Confirmed AL-CA diagnosis, receiving standard AL-CA treatment (chemotherapy e.g., Daratumumab-based regimen + supportive cardiac care). Exclusion: Active infection, advanced malignancy (life expectancy \<12 months), severe cognitive impairment/immobility affecting imaging compliance/follow-up. 4. Study Design \& Procedures: Design: Single-center prospective cohort study. Intervention: Participants receive standard-of-care treatment for AL-CA as per guidelines (chemotherapy regimen based on Daratumumab, Bortezomib, Cyclophosphamide, Dexamethasone; tailored cardiac support including diuretics, rate control, anticoagulation if needed). Procedures: Baseline: Upon enrollment, participants undergo comprehensive assessment: \[¹⁸F\]FAPI PET/CT scan, 3D CMR scan, blood tests (NT-proBNP, troponin, free light chains, etc.), clinical staging (Mayo 2012), functional assessment (NYHA class), quality of life questionnaire (KCCQ). Imaging: Specialized software (Siemens True D) performs cross-platform fusion of PET/CT and 3D CMR images. Radiomics features are extracted from the fused images using dedicated software (Siemens FeAture Explorer). Follow-up: Clinical: Every 3 months (symptoms, medication adherence, adverse events, lab tests including NT-proBNP). Imaging: Repeat \[¹⁸F\]FAPI PET/CT and 3D CMR scans at 6 months post-baseline. Radiomics features are extracted again. Endpoints: Primary endpoint is 12-month all-cause mortality. Secondary endpoints include re-hospitalization rates and changes in NYHA class. Follow-up continues until the 12-month endpoint for all participants. Data Analysis: Machine learning (LASSO-Cox regression) is used to select key radiomics features from baseline and 6-month scans and integrate them with quantitative imaging parameters (FAPI uptake volume, SUVmax, LGE burden, ECV) and clinical data to build prognostic models predicting 12-month survival. 5. Comparison: Researchers will compare the predictive performance of the developed multi-modal radiomics model against: * Traditional clinical biomarkers: NT-proBNP levels and Mayo Clinic staging. * Standard quantitative imaging parameters alone: Such as myocardial FAPI uptake volume, SUVmax, or CMR-derived extracellular volume (ECV) measured at baseline and 6 months. The goal is to demonstrate superior accuracy in predicting 12-month all-cause mortality using the integrated radiomics approach.

A Study of Metabolically Armed BCMA CAR-T Cells Therapy for Patients With Relapsed and/or Refractory Plasma Cell Neoplasms.
NCT06971848
Biotherapies are biological (extracted from an organism or living tissue) or biotechnological drugs used in the treatment of multiple conditions, such as autoimmune inflammatory diseases, cancers, and hematologic diseases. In recent years, these biotherapies have notably emerged in the treatment of cancers and hematologic disorders. As such, most patients with cancers or hematologic diseases will likely receive a biotherapy as part of their care pathway. These biotherapies are associated with various side effects, including hypersensitivity or allergic reactions, which are often poorly characterized in clinical trials. These reactions manifest as symptoms without specific dermatologic or allergologic semiology (such as itching, erythema, shortness of breath, sometimes digestive issues, or discomfort, and in some cases, an anaphylactic reaction). Unlike other treatments, such as antibiotics and neuromuscular blockers, there are currently no guidelines on the concentrations to use in skin tests for biotherapies. We propose conducting prospective clinical research to scientifically establish the concentrations to be used when investigating hypersensitivity to a biotherapy, in line with best practice recommendations for drug skin testing.
NCT05486481
This phase I/II trial tests the safety, side effects, and best dose of venetoclax, daratumumab, and dexamethasone for the treatment of systemic light-chain amyloidosis in patients with a deoxyribonucleic acid (DNA) abnormality called a translocation involving chromosomes 11 and 14, or "t(11;14)". Venetoclax works by attaching to a protein called Bcl-2, in order to kill cancer cells. Daratumumab works by binding to a target on the surface of cancer cells called Cluster of differentiation 38 (CD38). When daratumumab binds to CD38, it enables the immune system to find the cancer cell and kill it. Dexamethasone is a type of drug called a corticosteroid. A corticosteroid is a drug made of artificial steroid hormones, that are used to treat symptoms such as inflammation (swelling and irritation to a part of the body). The combination of these medications may more effectively treat patients with systemic light-chain amyloidosis and t(11;14).
NCT02245867
The purpose of this study is to examine the tolerance, safety, pharmacokinetics, and possible clinical benefit of the good manufacturing practice (GMP)-grade amyloid fibril-reactive chimeric (Ch) IgG1 mAb 11-1F4 in patients with amyloid light-chain (AL) amyloidosis. The phase 1a part will involve at least 3 patients and a maximum of 18 patients. The first patient will receive the starting dose of the antibody and, if tolerated, the following patients will each receive (if tolerated) progressively higher doses of the antibody. Patients in part 1a of the trial will receive only one infusion of the drug. Patients treated in the phase 1a part receive lower dosage which might not be effective. Once the maximal tolerated dosage is established during the phase 1a part, the investigators will accrue patients to the phase 1b part of the trial. Patients will receive 4 infusions, once each week for 4 weeks. Patients who were treated in the part 1a of the trial and showed no toxicity can be also treated in the part 1b of the trial. The first patient will receive the starting dose of the antibody and, if tolerated, the following patients will each receive (if tolerated) progressively higher doses of the antibody. When the investigators reach the maximum tolerated dose without toxicity, the investigators will enroll another 4 patients to receive the same dose. If there are no toxicities, another 4 patients will be treated at the next dose level, and so forth. Patients treated in Phase 1b may receive lower dosages which might not be effective. The goal of Phase 1b is to establish the tolerance and possible beneficial effects of 11-1F4. If successful, treatment with this antibody would represent a novel approach in the care of individuals with AL amyloidosis.
NCT06769555
The goal of this clinical trial is to evaluate the effectiveness and safety of CM-336, which is a BCMA/CD3 BiTE, in patients with relapsed/refractory AL amyloidosis or newly diagnosed AL amyloidosis with insufficient depth of hematologic response after induction therapy.
NCT04839003

NCT05066607
This phase 2 study ain to evaluate the efficacy of Isatuximab plus Pomalidomide and Dexamethasone (IPd), in patients with AL amyloidosis not in VGPR or better after any previous therapy. It will enrolled 46 patients (34 in France and 12 in Australia) through 15 sites (11 in France and 4 in Australia).
NCT04210791
This study mainly evaluated the efficacy and safety of autologous stem cell transplantation for the treatment of AL amyloidosis, the role of induction and maintenance therapy in autologous stem cell transplantation, and the long-term efficacy and prognosis risk factors of autologous stem cell transplantation for the treatment of AL amyloidosis.
NCT06186167
This single-practice prospective cohort study aims to enhance the diagnosis of cardiac amyloidosis in high-risk patients undergoing standard cardiac device implantation. By analyzing chest wall fat tissue, which is usually discarded, we aim to determine the diagnostic yield of such biopsies for amyloidosis and to develop a predictive screening model based on clinical, lab, and imaging data. The study, running from December 2023 to December 2024, expects to enroll 100 patients and may provide a new, non-invasive diagnostic avenue for this condition.
NCT04695340
Familial amyloidosis is a rare disease that mainly affects the nerves and heart, but also more rarely the eyes and kidneys. This disease is due to a mutation in the gene encoding the synthesis of transthyretin, resulting in a modification of the translated protein. This abnormal protein and its derivatives are deposited in the form of a toxic "amyloid" substance in tissues and organs, altering their functions, particularly in the gastrointestinal tract. From a gastrointestinal perspective, different treatments can be proposed in the absence of specific recommendations for familial amyloidosis. The hygienic and dietary measures consist of avoiding tobacco, alcohol and carbonated drinks, limiting fatty meals rich in poorly digestible fibers, and splitting meals. If this fails, metoclopramide and domperidone are suggested. As a second-line erythromycin, can be used with caution because of cardiac risks and drug interactions. Polyethylene glycol-based osmotic laxatives can be used to treat constipation. Alternating diarrhea and constipation can be treated with ispaghul-based laxatives, aiming at transit regulation. Finally, refractory diarrhea can be treated with the administration of loperamide. If this fails, treatment with a somatostatin analogue may be offered. However, all these treatments can present significant side effects, therefore natural alternatives are often sought. Psyllium in particular regulates transit by normalizing stool consistency: it is effective against digestive disorders such as constipation, but it is also effective in the event of diarrhea. It allows the formation of a viscous gel by the hydrophilicity of polysaccharides macromolecules, increasing the fecal bowl which stimulates peristalsis and facilitates defecation. The WHO has recognized that Psyllium is superior to wheat bran in the treatment of irritable bowel syndrome. The main objective of the study is to assess the effect of daily Psyllium administration on digestive quality of life in familial amyloidosis patients who suffer from digestive disorders.
