Active clinical trials for "Amyloidosis"

Familial amyloid neuropathies (FAP) are hereditary disease due to a mutation of the tranthyretin gene (TTR). These neuropathies are severe and life frightening. Asymptomatic carrier of TTR mutation are now detected in large TTR-FAP family. However, it is very hard to detect the moment where a TTR mutation carrier become symptomatic: too early diagnosis exposes the patients to side effect of the treatment and too late diagnosis exposes the patient to disease progression and clinical sequels. Neurological monitoring comprises clinical examination, electrophysiology and imaging. Sensitivity and specificity of these tools are not sufficient and we have to develop new biomarkers sensitive enough to detect modifications under treatment and the moment where a TTR mutation carrier become symptomatic Magnetic resonance imaging (MRI) can well evaluate neuromuscular diseases. Electrophysiological examination is also a good tool to evaluate NAF. MUNIX is a technique that permits to estimate the number of motor unit in one muscl. MUNIX is related to the disability in chronic inflammatory neuropathies and could be more sensitive than clinical scales and other electrophysiological data to detect modification of the disease in TTR-FAP. The objective of this exploratory study is to test the applicability of MUNIX and MRI as early measures for detecting the transition from asymptomatic to symptomatic TTR-FAP. In symptomatic TTR-FAP we will determine if MUNIX and MRI data are related to clinical deficiency and disability of the patients. This is a transversal exploratory study. If we manage to demonstrate that MRI and MUNIX can segregate symptomatic versus asymptomatic TTR mutation gene carriers, we will propose a longitudinal study with a follow up of more asymptomatic gene carriers.

[18F]Florbetaben PET/CT imaging will noninvasively assess amyloid deposition in systemic amyloidosis.

ATTRwt (also known as senile systemic, or senile cardiac amyloidosis) is a progressive heart disease, causing congestive heart failure. It is caused by amyloid protein deposits in the heart, that are derived from a normal protein, TTR, made in the liver. The aim of the study is to determine whether lowering the blood levels of TTR, by a weekly injection of a compound designed specifically to do this, will slow the progression of the disease when treated patients are compared to previously-followed patients who were not receiving this drug. The study also aims to determine how well this drug is tolerated and the existence and severity of any drug side-effects.

The study is designed to test the relationship between measurements of brain amyloid using florbetapir F 18 PET imaging and true levels of amyloid by dissection of the brain at autopsy. Amyloid in the brain is a key feature of Alzheimer's Disease (AD).

GSK3039294 has been developed to offer an orally available alternative to parenteral GSK2315698 (miridesap) for plasma serum amyloid P component (SAP) depletion prior to and following use of anti-SAP Monoclonal Antibody (mAb) in the treatment of systemic amyloidosis. The primary objectives of the study are to assess the cardiac arrhythmic potential of GSK3039294 and evaluate safety and tolerability of repeat doses of GSK3039294, in healthy subjects relative to placebo for the same duration. This study will consist of two parts, Part A and a conditional Part B. Part A is designed as a randomized double-blinded, 3 period, placebo-controlled, repeat-dose, crossover study. The decision to initiate Part B will be based on an evaluation of data from Part A, which will include an overall assessment of safety, pharmacokinetics (PK) and pharmacodynamics (PD). In Part A, there will be three treatment periods with 7 days of dosing in each and minimum 7-day washout period between each treatment session. Each subject will receive two dose levels of GSK3039294 and placebo. In Part B, there will be two treatment periods with 7 days of dosing in each and minimum 7-day washout period. Each subject will receive one dose level of GSK3039294 and placebo. In Part A, approximately 48 subjects will be recruited for an estimated total of 36 completers. In Part B, approximately 32 subjects will be recruited for an estimated total of 24 completers. The study will last up to approximately 10 weeks from screening to follow-up.

This is a clinical proof-of-concept (PoC) study of DNA vaccination after SAP depletion. The investigators will measure the immune responses to DNA vaccination against HIV-1 in healthy adult male volunteers, comparing a group in whom SAP has been completely depleted at the time of DNA vaccination and a control group vaccinated without SAP depletion.

The aim of this study is to evaluate the efficacy, safety of a single dose of BAY 94-9172 (ZK 6013443) as an investigational medicinal product (IMP) in detecting cerebral protein-plaque (amyloid beta) with positron emission tomography (PET). IMP binds to amyloidal beta protein accumulating in brain tissue already from early stages of Alzheimer's disease (AD). IMP is therefore a potential tracer to be used for detecting amyloid plaques. For each subject it is required to visit the study centre during the screening phase, on the PET imaging day and for 1 follow-up visit on the next day. A telephone call for safety follow-up will be performed 7 days after IMP administration. During the screening phase the subject's medical, neurological and surgical history, specific laboratory tests related to AD, MRI of the brain and certain neuro-psychiatric tests will be performed. Clinical safety measures (physical examinations, vital signs, electrocardiogram (ECG) and laboratory tests) will be performed on the PET imaging day before IMP injection and monitored during and after two PET imaging sessions. Clinical safety measures will be performed again on the follow-up visit next day. The results of PET imaging with IMP will be compared between probable AD patients and healthy volunteers (HV). The clinical diagnosis is based on international validated and accepted criteria and established after comprehensive clinical and neuro-psychiatric examinations

Transthyretin (TTR) amyloidosis is a rare disabling disorder that can be hereditary or sporadic. Depending on the form, various tissues are affected. While in hereditary cases, neuropathy is predominant, cardiac impairment is the main manifestation in the sporadic form. The main objective of this project is to evaluate the proportion of patients with neuropathy in a population of patients with a non-mutated TTR amyloid cardiopathy condition.

The purpose of this study is to test the safety and efficacy of Selinexor and Dexamethasone and see what effects it has on AL amyloidosis.
