Filter by: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.
This is a dose finding study to evaluate the safety and determine the maximum tolerated dose of carfilzomib in patients with previously treated systemic light-chain amyloidosis.
The study will be conducted in two parts. The first (Part A) will be an open label single dose escalation part beginning with the proposed starting dose level of GSK2398852 as 5 milligram (mg) [approximately equivalent to 0.1 mg/kilogram (kg)]. The next escalation dose levels are proposed as 1 mg/kg, 3 mg/kg, 10 mg/kg and 30 mg/kg. GSK2315698 will be administered at variable doses until the concentration of the serum amyloid P component monoclonal antibody (SAP mAb) has fallen below 100 nanogram/millilitre (ng/mL). Decisions about these next dose levels will be made following safety review of the prior subjects' data; dose levels may be changed (increased and lowered) and dose levels may be repeated depending on the observed safety such that Part A extension study may be performed. In addition, pharmacokinetics of GSK2315698 (SAP depleter) and GSK2398852 (anti-SAP mAb), and circulating SAP concentrations will be assessed. Dose escalation in Part A will continue to the highest well tolerated dose or the highest allowable dose. Subjects will be closely monitored and will undergo Equilibrium contrast Magnetic Resonance Imaging (EqMRI) including organ volume, Elastography and Liver Biopsy if required. Part B will be a randomized partially blinded part with the principal objective of assessing the dose response of the GSK2398852 in more detail. Subjects will be assigned to one of approximately 5 dose groups from Part A. The precise selection of numbers of subjects and dose levels will be informed by the results from Part A.
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.
The purpose of this study is to evaluate the efficacy and safety of inotersen given for 65 weeks in participants with Familial Amyloid Polyneuropathy (FAP).
This phase I trial studies the side effects and best dose of pomalidomide and bortezomib when given together with dexamethasone in treating patients with amyloid light-chain amyloidosis or light chain deposition disease. Biological therapies, such as pomalidomide, may stimulate the immune system in different ways and stop abnormal cells from growing. Bortezomib may stop the growth of abnormal cells by blocking some of the enzymes needed for cell growth. Giving pomalidomide and bortezomib together with dexamethasone may be an effective treatment for amyloid light-chain amyloidosis or light chain deposition disease
Dose escalation study to determine the maximum tolerated dose of NEOD001 in approximately 30 subjects with AL amyloidosis. Expansion phase to evaluate safety, efficacy and pharmacokinetics of NEOD001 in 25 additional subjects at the maximum tolerated dose.
The primary aim of this pilot study is to determine whether amyloid deposits in the heart can be measured non-invasively by F-18 florbetapir (Trade Name: Amyvid) positron emission tomography (PET) in 30 individuals with documented cardiac amyloidosis. We will also enroll 15 individuals without cardiac amyloidosis to undergo the F-18 florbetapir imaging as a control group. The primary hypothesis of this study is that a specific amyloid binding radiotracer will bind to the myocardial amyloid deposits and help quantify cardiac amyloid burden. A secondary aim of this study is to determine reproducibility of F-18 florbetapir imaging of the myocardium.
The tetracycline antibiotic doxycycline disrupts A beta amyloid fibrils (AB) in Alzheimer's disease, transthyretin (ATTR) amyloid fibrils in familial amyloidotic polyneuropathy, and immunoglobulin light chain (AL) amyloid fibrils in transgenic mouse models of disease. If untreated, amyloid deposits impair organ function, affecting the morbidity and mortality of patients. This single-center, twelve-month, open-label, prospective, pilot phase II study aims to determine whether doxycycline reduces amyloid deposits and improves organ function in patients with systemic or localized amyloidosis. The investigators plan to enroll patients with measurable amyloid disease according to internationally-accepted diagnostic criteria. Patients must have stable organ function at enrollment. Eligible subjects not receiving active treatments for amyloidosis affecting their kidneys, heart, aerodigestive tracts, peripheral or autonomic nervous system(s), lungs, eyes, skin, bladder, or breasts will undergo evaluations at baseline, 6 months, and 12 months - or more frequently as clinically indicated. Over 45 years experience indicates doxycycline is a safe, well tolerated antibiotic. The investigators will use standard grading systems to assess doxycycline response following twelve months of treatment.
The purpose of this study is to provide continued access of ixazomib and/or other study medications and to continue collecting relevant safety data to monitor participant's safety, determine whether dexamethasone plus IXAZOMIB improves hematologic response, 2-year vital organ (that is, heart or kidney) deterioration and mortality rate versus a physician's choice of a chemotherapy regimen in participants diagnosed with relapsed or refractory systemic light chain (AL) amyloidosis.
