Filter by:Hereditary (familial) amyloidosis arising from the misfolding of a mutated or variant transthyretin, is the most frequent form of amyloid cardiomyopathy in the Caribbean basin. Affected organs invariably harbor extracellular amyloid deposits in the myocardium. Circulating or pre-fibrillar amyloidogenic proteins are implicated in the disruption of cell function. The investigators aim is to demonstrate that transthyretin mediated amyloid disease alter the mitochondrial function of cardiac cells.
The frequency of cardiac amyloidosis among patients presenting with a so-called left ventricular hypertrophy remains unknown. This problem is especially relevant in the Caribbean's, where an amyloidosis-prone mutation of transthyretin gene might be frequent.
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.
This pilot phase I clinical trial studies how well copper 64Cu-DOTA-daratumumab positron emission tomography works in diagnosing patients with multiple myeloma that has come back. Diagnostic procedures, such as copper 64Cu-DOTA-daratumumab positron emission tomography, may help evaluate the extent of multiple myeloma in patients prior to the initiation of treatment and ultimately monitor disease status/response during and post treatment.
This phase I trial studies the side effects and best dose of daratumumab, ixazomib, and dexamethasone in treating participants with amyloid light chain amyloidosis. Monoclonal antibodies, such as daratumumab, may interfere with the ability of tumor cells to grow and spread. Drugs used in chemotherapy, such as ixazomib and dexamethasone, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving daratumumab, ixazomib, and dexamethasone may be effective in treating participants with light chain amyloidosis.
The cerebral amyloïd angiopathy ( AAC) is a disease characterized by deposits of beta-amyloid peptids in the walls of the arteries of young and average calibre of the brain and the leptomeninx. The incidence of the AAC increases strongly with the age and represents a major cause of spontaneous brain haemorrhage to people over 60. The main demonstration is the lobar brain haemorrhage, the other ones are bleedings under arachnoid cortical and microbleedings leading to cognitive decline. Anatomical studies reported the presence of cortical infarcts in patients having amyloïd deposits suggesting an association between asymptomatic cortical cerebral infarcts and AAC. However prevalence and meaning of these infarcts in patients having an AAC remain badly known because of studies on low number of patients and the rarity of radiological analyses of these infarcts .A better knowledge of these asymptomatic cortical infarcts would allow to dread better cognitive disorders(confusions) presented by these patients, and to develop preventive strategies. Besides, the risk factors of severity of the AAC are little studied.
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.
National, multicenter, epidemiological, longitudinal protocol to investigate the hATTR prevalence in an at-risk population for Hereditary Transthyretin Amyloidosis (hATTR) and subjects diagnosed with hATTR, to monitor the clinical status in TTR positive subjects and to establish hATTR biomarker/s
Light chain (AL) amyloidosis is a bone marrow disorder that affects a wide range of organs that can lead to organ dysfunction and death. Amyloid is an abnormal protein that is produced in your bone marrow and cannot be broken down. It builds up in different organs preventing them from working well. The most commonly affected organs are the kidneys, heart, liver, spleen, nervous system, and digestive tract. Treatment with chemotherapy can stop the growth of abnormal cells that produce this abnormal protein. Decrease in amyloid protein in the body improves the function of the affected organs. The primary purpose of this study is to determine the safest dose of the medications and how well you tolerate them or the "maximum tolerated dose" (MTD). The study uses Ixazomib in combination with cyclophosphamide and dexamethasone to treat people with newly diagnosed AL amyloidosis. This combination of medications is an oral regimen that is taken over 6 cycles. The first part of study will determine the safety of this regimen and the second part of the study will determine how effective this combination of drugs is to treat your disease.
