Filter by: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.
The aim of this study is to evaluate the removal of midle molecules and inflammatory cytokines with the Theranova-500 ™ dialyzer (medium cut-off membrane, Baxter®) versus a high flux dialyzer Elisio-21H ™ (High-flux membrane, Nipro®) in chronic hemodialysis. Evaluation of nutritional parameters, inflamatory parameters and oxidative stress will also be carried out. Finally, the investigators will compare hepcidin levels and the erythropoietin resistance index between the two groups.
Familial amyloid neuropathy due to transthyretin gene mutations (TTR-FAP) is a rare autosomal dominant inherited disease resulting in the abnormal multi-system deposition of amyloid proteins. These deposits produce a multi-organ disease. AP is usually fatal 10 to 15 years after onset of symptoms if untreated. The prevalence of the disease remains still poorly understood and usually the search for this pathology is done in a third line of investigation. So the average time to diagnosis is extremely long, from 12 to 24 month. Now that the investigators have etiological treatment ( famidis (Vyndaqel®) and Diflunisal (Dolobid)) of this disease, it is essential to be able to detect FAP patients as early as possible. With this study, investigator decided to test for TTR mutation all patients presented with neuropathy of unknown etiology at the first line of investigation. The goal of this study is to evaluate the prevalence of FAP-TTR among neuropathy and defined the best strategy to test this population for TTR mutations.
Diagnostic tests designed to detect Alzheimer's disease (AD) pathology are increasingly popular in research on cognitive aging and AD. Due to concerns that information from such tests may be misunderstood, psychologically harmful, and of unclear clinical significance, results of pre mortem tests of AD pathology have typically been withheld from research participants. However, as the reliability and potential clinical significance of tests like brain amyloid imaging have become clear, there is a pressing need to revisit the practice of unilaterally withholding such information from research participants and identify responsible approaches to communicating individual results. Amyloid imaging results may be particularly relevant to mild cognitive impairment (MCI), a population for whom a growing body of evidence suggests that such testing may provide valuable prognostic and planning information, despite the unavailability of interventions to alter one's clinical course. Our preliminary work suggests that research participants with MCI and their family members are receptive to and capable of understanding information about the purpose, results, and implications of amyloid imaging when presented using a standardized approach developed by our interdisciplinary team. Building on this work, the proposed study will examine a well characterized sample of MCI care dyads (patient + family member) who will be randomized to either receive the opportunity to decide if they would like to pursue an amyloid PET Scan, or be randomized to not receive that opportunity (and will serve in the no-scan comparison group). This study aims to test hypotheses that examine how receiving amyloid imaging results will impact understanding of, and perceived self-efficacy for coping with, MCI among both patients and care partners.
Cardiac amyloidosis is a disorder characterized by the deposition of abnormal proteins called amyloid in the heart tissue. This makes it difficult for the heart to function properly. The investigators wish to evaluate if the radiopharmaceutical 18F‑Florbetaben (Neuraceq®) that targets beta amyloid can also identify cardiac amyloid deposition.
The purpose of this study is to change the concentration of amyloid-beta in human cerebrospinal fluid (CSF) by modification of sleep efficiency.
The primary aim of this study will be to examine the diagnostic utility of 18-F Florbetapir PET/MR (Positron Emission Tomography/Magnetic Resonance) in imaging patients with pathologically-confirmed systemic amyloidosis involving the peripheral nerves and compare these results to non-amyloid diseased controls.
This study is intended to examine the impact of learning amyloid brain imaging results among asymptomatic older adults, and how to safely communicate these results and educate on the risk of developing Alzheimer's disease.
This is the first study in which GSK2315698 will be administered in Japanese population. The primary objective of the study is to investigate safety and tolerability, pharmacokinetics, and pharmacodynamics after single intravenous infusion in healthy subjects. This will be a single center, double-blind, randomized, placebo-controlled, dose-ascending study. Subjects in Cohort 1 will attend 3 dosing sessions, and will be randomized to one of the 3 groups. Each group will receive GSK2315698 and Placebo in a defined sequence. The dose levels of GSK2315698 are set to 10 milligrams (mg) per hour (hr), 20 mg/hr, and 40 mg/hr, to be administered over 1 hour. Dosing sessions 1 and 2, and dosing sessions 2 and 3, will be separated by a washout period of at least 8 and 10 days, respectively. Subjects in Cohort 2 will attend a single dosing session, and will be randomized to receive either GSK2315698 20 mg/hr or Placebo, over a period of 15 hours. A sufficient number of subjects will be randomized such that 18 subjects (9 in each cohort) complete the study. The duration of participation for any subject in this study will be approximately 59 days.
The primary objective of this study was to evaluate safety and tolerability of ACZ885 in this extension study. This extension study offered the opportunity for participants who completed Epoch 4 of the preceding CACZ885N2301 (NCT02059291) study to continue to be treated with ACZ885 until approval in Japan of the drug in Periodic Fever Syndromes or until development of ACZ885 in Periodic Fever Syndromes was suspended.
