Active clinical trials for "Amyloidosis"

RATIONALE: Drugs used in chemotherapy work in different ways to stop the growth of plasma cells, either by killing the cells or by stopping them from dividing. Having a stem cell transplant to replace the blood-forming cells destroyed by chemotherapy, allows higher doses of chemotherapy to be given so that more plasma cells are killed. By reducing the number of plasma cells, the disease may progress more slowly. PURPOSE: This phase II trial is studying how well autologous stem cell transplant works in treating patients with persistent or recurrent primary systemic (AL) amyloidosis.

GSK3039294 has been developed in order to offer an orally available alternative to parenteral CPHPC (GSK2315698 [metabolite of GSK3039294]) for plasma serum amyloid P component (SAP) depletion prior to use of anti SAP monoclonal antibody (mAb) in the treatment of systemic amyloidosis. This phase 1 study is intended to study safety, tolerability and pharmacokinetic (PK) profile of GSK3039294 in humans. This study consists of three parts. Part A will evaluate safety and tolerability of single doses of GSK3039294 in healthy subjects, Part B will evaluate safety and tolerability of repeat doses of GSK3039294 in healthy subjects, and Part C will evaluate safety and tolerability of repeat doses of GSK3039294 in subjects with systemic amyloidosis. Part A is a single dose, open label, dose escalation study. Two cohorts of subjects will be enrolled to provide data from 6 subjects per cohort and up to 4 different doses (2 dose levels per cohort) of GSK3039294 will be tested. For Cohorts 1 and 2, each subject may take part in two dosing periods. Part B is repeat dose, open label, dose escalation study. Sufficient number of subjects will be enrolled in Cohort 3a to ensure 6 completers (Cohort 3b will be conducted if required) and GSK3039294 will be administered repeatedly for a total of 21 days. Each subject will take part in a single study period. In Part C a single dose level of GSK3039294 will be tested for 21 days repeat dose, in 12 subjects with systemic amyloidosis. Each subject will take part in a single study period. The total duration for Part A is approximately 8 weeks, Part B is approximately 8-9 weeks, and Part C is approximately 13 weeks.

The goal of this clinical research study is to find the highest tolerable dose of pomalidomide that can be given in combination with melphalan and dexamethasone that can be given to patients with AL amyloidosis. The safety of this drug combination will also be studied. Pomalidomide is designed to change the body's immune system. It may also interfere with the development of tiny blood vessels that help support tumor growth. This may decrease the growth of cancer cells. Melphalan is designed to damage the DNA (genetic material) of cells, which may cause cancer cells to die. Dexamethasone is a corticosteroid that is similar to a natural hormone made by your body. Dexamethasone is often given to Multiple Myeloma (MM) patients in combination with other chemotherapy to treat cancer. Planned Phase I/II Study terminated early during Phase I portion without continuation to Phase II.

The purpose of this study to assess the longitudinal changes in left and right ventricular global strain after chemotherapeutic strategies in cardiac light chain amyloidosis.

The purpose of this study to assess the longitudinal changes in left atrial strain and supraventricular arrhythmia burden after chemotherapeutic strategies in cardiac light chain amyloidosis.

The goal of this research study is to determine whether changes in organ-specific uptake of 124I- AT-01 can be measured by PET/CT imaging and further, whether these values correlate with changes in a subject's disease status and thereby enable monitoring of disease response over time in terms of organ-specific amyloid load.

This is a multi-center, international, randomized, double-blind, placebo-controlled, two-arm efficacy and safety study in subjects newly diagnosed with AL amyloidosis. Subjects will remain on-study until study completion, which will occur when all primary endpoint events (all-cause mortality or cardiac hospitalizations) have been reached.

Cerebral amyloid angiopathy (CAA) is a major cause of lobar intracerebral hemorrhage (ICH) in the elderly with high risk of recurrence. The investigators aim to determine the relationship between cortical superficial siderosis (cSS), a MRI hemorrhagic marker of CAA and the risk of symptomatic ICH recurrence in a multicentric prospective cohort of patients with acute lobar ICH related to CAA. The investigators hypothesize that patients with cSS have an increased risk of recurrent symptomatic ICH relative to those without cSS.

Evaluate safety and toxicity/adverse events associated with delivery of low dose whole brain irradiation in patients with early Alzheimer's dementia according to the National Institute of Neurological and Communicative Disorders and Stroke and the Alzheimer's Disease and Related Disorders Association (NINCDS-ADRDA) criteria.. As a secondary goal it will establish whether or not the intervention with low dose whole brain irradiation stabilizes or decreases cerebral amyloid deposits and whether these correlate with the recognized progression of Alzheimer's dementia. The investigators will also collect information from the FDG and Amyvid® PET Scans to determine if there is any correlation between neurocognitive/quality of life scores and changes in amyloid plaque size, number and location.

RATIONALE: Drugs used in chemotherapy work in different ways to stop the growth of plasma cells, either by killing the cells or by stopping them from dividing. Having a peripheral stem cell transplant to replace the blood-forming cells destroyed by chemotherapy, allows higher dose of chemotherapy to be given so that more plasma cells are killed. Giving a chemoprotective drug such as amifostine may protect kidney cells from the side effects of chemotherapy. PURPOSE: This phase I trial is studying the side effects and best dose of melphalan given together with amifostine in treating patients who are undergoing peripheral stem cell transplant for primary systemic amyloidosis.
