Active clinical trials for "Immunoglobulin Light-chain Amyloidosis"

The STI-6129-001 study is a three-stage, multicenter, open-label, dose-finding, phase 1b/2a trial. It is designed primarily to identify the recommended phase 2 dose (RP2D) of STI-6129 by assessing the safety, preliminary efficacy and pharmacokinetics of this anti-CD38-Duostatin 5.2 antibody-drug conjugate (ADC) for the treatment of relapsed or refractory systemic AL amyloidosis. The patients that will be treated with STI-6129 in this trial are relapsed or refractory systemic AL amyloidosis patients who have received prior lines of treatment.

This is a single arm, Open-Label, Phase 1/2 Study of ZN-d5 for the Treatment of Relapsed or Refractory Light Chain (AL) Amyloidosis.

This phase I/Ia trial finds the best dose and side effects of venetoclax given in combination with ixazomib citrate and dexamethasone in treating patients with light chain amyloidosis that has come back (relapsed) or does not respond to treatment (refractory) and who have an abnormal genetic change [translocation t(11;14)]. Venetoclax is in a class of medications called B-cell lymphoma-2 (BCL-2) inhibitors. It may stop the growth of cancer cells by blocking Bcl-2, a protein needed for cancer cell survival. Ixazomib citrate is in a class of medications called proteasome inhibitors. It works by helping to kill cancer cells. Anti-inflammatory drugs such as dexamethasone reduce inflammation by lowering the body's immune response and are used with other drugs in the treatment of some types of cancer. Combination therapy with venetoclax, ixazomib citrate and dexamethasone may be effective in treatment of relapsed or refractory light chain amyloidosis.

The purpose of this study is to learn if Ixazomib maintenance treatment (chemotherapy) works to control the disease. Through this study, the investigators hope to learn more about ways to prevent or delay relapse of AL Amyloidosis.

The main purpose of this study is to examine the outcome of a combined bone marrow and kidney transplant from a partially matched related (haploidentical or "haplo") donor. This is a pilot study, you are being asked to participate because you have a blood disorder and kidney disease. The aim of the combined transplant is to treat both your underlying blood disorder and kidney disease. We expect to have about 10 people participate in this study. Additionally, because the same person who is donating the kidney will also be donating the bone marrow, there may be a smaller chance of kidney rejection and less need for long-term use of anti-rejection drugs. Traditionally, very strong cancer treatment drugs (chemotherapy) and radiation are used to prepare a subject's body for bone marrow transplant. This is associated with a high risk for serious complications, even in subjects without kidney disease. This therapy can be toxic to the liver, lungs, mucous membranes, and intestines. Additionally, it is believed that standard therapy may be associated with a higher risk of a complication called graft versus host disease (GVHD) where the new donor cells attack the recipient's normal body. Recently, less intense chemotherapy and radiation regimens have been employed (these are called reduced intensity regimens) which cause less injury and GVHD to patients, and thus, have allowed older and less healthy patients to undergo bone marrow transplant. In this study, a reduced intensity regimen of chemotherapy and radiation will be used with the intent of producing fewer toxicities than standard therapy. Typical therapy following a standard kidney transplant includes multiple lifelong medications that aim to prevent the recipient's body from attacking or rejecting the donated kidney. These are called immunosuppressant drugs and they work by "quieting" the recipient's immune system to allow the donated kidney to function properly. One goal in our study is to decrease the duration you will need to be on immunosuppressant drugs following your kidney transplant as the bone marrow transplant will provide you with the donor's immune system which should not attack the donor kidney.

Amyloidoses are systemic or acquired disorders characterized by the deposition in the extracellular spaces of amyloid fibers formed by proteins codified by mutated genes or non-mutated but misfolded proteins. Cardiac involvement in amyloidosis is an important determinant of the clinical presentation and can be found in patients with amyloid light-chain (AL) or transthyretin (ATTR) amyloidosis, the latter due to the deposition of normal proteins (formerly known as senile amyloidosis) or mutated proteins. Cardiac amyloidosis (CA) has a poor prognosis that further worsens if the diagnosis and treatment are delayed. Nuclear medicine techniques have emerged as important tools for the diagnosis and characterization of CA. It has been recently demonstrated that cardiac uptake of bone tracers allows to identify the deposition of transthyretin in the heart, while it is not useful for the diagnosis of AL-CA, which currently requires the histological demonstration of amyloid fibers in a tissue sample taken with invasive procedures such as an endomyocardial biopsy. Recently, some PET tracers developed to identify beta-amyloid deposits in the brain proved able to detect an uptake even in the heart; nonetheless their possible use to diagnose CA is still debated. One of those tracers is florbetaben labelled with 18F, which displays a high binding affinity with beta-amyloid in the brain, while the experience on its use to identify extracranial amyloid deposits is still limited. Three studies have reported a cardiac uptake of 18F-florbetaben in AL or ATTR amyloidosis. Tracer uptake could be detected starting from 15 minutes after tracer administration. In a case series of 60 patients (20 with AL-CA, 20 with ATTR-CA and 20 with CA suspected but excluded) we demonstrated that the evidence of a myocardial uptake in a late acquisition can effectively discriminate AL- from ATTR-CA or other conditions. Indeed, patients with AL-CA displayed an intense and persistent myocardial uptake in static acquisitions at all time points, while patients with ATTR-CA and those without CA displayed a rapid reduction of the uptake after the early acquisition. This study aims to compare the performance of PET/CT with 18F-florbetaben to diagnose AL-CA compared with the current diagnostic standard, which requires a tissue biopsy. Primary objective: To define the agreement (with its 95% confidence interval) between two diagnostic approaches to the diagnosis of AL-CA in patients with a monoclonal protein: the traditional invasive approach and a non-invasive approach using the visual assessment of 18F-florbetaben PET/TC. Secondary objectives: To define the diagnostic performance of PET/CT with 18F-florbetaben (visual evaluation) in terms of sensitivity, specificity, positive and negative predictive value; To define cut-offs from myocardial uptake quantification to confirm or discard AL-CA among patients with suspected CA and a monoclonal protein, compared to the standard diagnostic algorithm, from quantitative uptake values; To assess the changes in the degree of myocardial 18F-florbetaben uptake over 12 months in patients with AL-CA; To assess the safety and tolerability of PET/CT with 18F-florbetaben in patients evaluated for suspected CA.

This is an open-label, multi-center pivotal Phase 3 study to visually and quantitatively assess PET images obtained after single application of 300 MBq [18F]florbetaben and PET scanning of patients with suspected cardiac amyloidosis.

Cardiac amyloidosis is a major cause of early treatment-related death and poor overall survival in individuals with systemic light chain amyloidosis. This project will develop a novel approach to visualize cardiac amyloid deposits using advanced imaging methods. The long-term goal of this work is to identify the mechanisms of cardiac dysfunction, in order to guide the development of novel life-saving treatments.

This randomized phase II trial studies how well lenalidomide, dexamethasone, and eotuzumab with or without cyclophosphamide work in treating patients with primary amyloidosis that has come back after a period of improvement. Drugs used in chemotherapy, such as lenalidomide, dexamethasone, and cyclophosphamide, 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. Monoclonal antibodies, such as eotuzumab, may interfere with the ability of cancer cells to grow and spread. Giving lenalidomide, dexamethasone, and eotuzumab with cyclophosphamide may work better in treating patients with primary amyloidosis.

RATIONALE: Giving bortezomib together with melphalan and dexamethasone may be an effective treatment for primary amyloidosis and light chain deposition disease. PURPOSE: This phase II trial is studying how well giving bortezomib together with melphalan and dexamethasone works in treating patients with primary amyloidosis or light chain deposition disease.
