Filter by: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 investigators expect to enroll 15 participants with relapsed or refractory IgM-associated AL amyloidosis onto this Phase II clinical trial. Idelalisib will be self-administered orally at a dose of 100 mg twice daily (may be increased to 150 mg (one tablet) twice daily after 3 months at investigator discretion). Participants will be treated until disease progression, unacceptable toxicity, or decision to withdraw from the trial. Disease evaluations will be performed every three months until disease progression.
Standard treatment for AL Amyloidosis is high-dose melphalan and stem cell transplant. This study will compare the safety and effectiveness of standard treatment with high-dose melphalan and stem cell transplant, compared with investigational bortezomib when used in combination with standard treatment with high-dose melphalan and stem cell transplant for AL amyloidosis.
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.
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 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
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 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.
In a proportion of patients with AL amyloidosis there is no improvement of cardiac function despite hematologic response to treatment. The aim of the study is to assess whether treatment with EGCG increases the rate of cardiac response in patients with AL amyloidosis who completed chemotherapy.
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.
