Active clinical trials for "Amyloidosis"

The purpose of this study was to evaluate the safety and clinical activity of long-term dosing with revusiran (ALN-TTRSC). Dosing has been discontinued; patients are being followed-up for safety.

The purpose of this study is to examine the tolerance, safety, pharmakinetics, and possible clinical benefit of the good manufacturing practice (GMP)-grade amyloid fibril-reactive chimeric (Ch) IgG1 mAb 11-1F4 in patients with amyloid light-chain (AL) amyloidosis. The phase 1a part will involve at least 3 patients and a maximum of 18 patients. The first patient will receive the starting dose of the antibody and, if tolerated, the following patients will each receive (if tolerated) progressively higher doses of the antibody. Patients in part 1a of the trial will receive only one infusion of the drug. Patients treated in the phase 1a part receive lower dosage which might not be effective. Once the maximal tolerated dosage is established during the phase 1a part, the investigators will accrue patients to the phase 1b part of the trial. Patients will receive 4 infusions, once each week for 4 weeks. Patients who were treated in the part 1a of the trial and showed no toxicity can be also treated in the part 1b of the trial. The first patient will receive the starting dose of the antibody and, if tolerated, the following patients will each receive (if tolerated) progressively higher doses of the antibody. When the investigators reach the maximum tolerated dose without toxicity, the investigators e will enroll another 4 patients to receive the same dose. If there are no toxicities, another 4 patients will be treated at the next dose level, and so forth. Patients treated in Phase 1b may receive lower dosages which might not be effective. The goal of Phase 1b is to establish the tolerance and possible beneficial effects of 11-1F4. If successful, treatment with this antibody would represent a novel approach in the care of individuals with AL amyloidosis.

The purpose of this study is to determine whether Q-Switched Nd:YAG Laser therapy are effective in reduction of Cutaneous macular amyloidosis.

The purpose of this study is to evaluate the efficacy of Enbrel in patients with primary systemic Amyloidosis.

RATIONALE: Autologous stem cell transplantation may be effective treatment for primary systemic (AL) amyloidosis. PURPOSE: This phase II trial is studying how well tandem (two) autologous stem cell transplantation works in treating patients with primary systemic (AL) 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 peripheral 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 giving high-dose melphalan together with peripheral stem cell transplant works in treating patients with primary amyloidosis or amyloidosis associated with multiple myeloma.

This clinical trial studies the side effects and best dose of giving fludarabine and total-body irradiation (TBI) together followed by a donor stem cell transplant and cyclosporine and mycophenolate mofetil in treating human immunodeficiency virus (HIV)-positive patients with or without cancer. Giving low doses of chemotherapy, such as fludarabine, and TBI before a donor bone marrow or peripheral blood stem cell transplant helps stop the growth of cancer or abnormal cells and helps stop the patient's immune system from rejecting the donor's stem cells. The donated stem cells may replace the patient's immune cells and help destroy any remaining cancer cells (graft-versus-tumor effect). Sometimes the transplanted cells from a donor can also make an immune response against the body's normal cells. Giving cyclosporine (CSP) and mycophenolate mofetil (MMF) after the transplant may stop this from happening.

Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Phase I trial to study the effectiveness of imatinib mesylate in treating patients who have advanced cancer and liver dysfunction

RATIONALE: Drugs such as CC-5013 and dexamethasone may be effective in treating primary systemic amyloidosis. PURPOSE: This phase II trial is studying CC-5013 to see how well it works with or without dexamethasone in treating patients with primary systemic amyloidosis.

The purpose of this study is to determine whether Tolcapone crosses from the blood stream into the fluid around the brain and stabilizes the protein that makes leptomeningeal amyloid. Tolcapone is a commercially available generic drug that treats Parkinson's disease. The Investigator plans to evaluate Tolcapone as a treatment for ATTR (Transthyretin Amyloidosis), a rare genetic disease often causing death within 5-15 years after diagnosis. ATTR is characterized by deposition of misfolded protein known as amyloid, in one or more organ systems (including the peripheral and autonomic nervous systems, the heart, the brain and the eyes). The age at which symptoms begin to develop varies widely ranging between 20 to 70 years old. ATTR is progressive, and some variants can have a fatal outcome within a few years of presentation. Treatment options include supportive and symptomatic care that may slow or stop progressive decline in functional state but do not alter the pathological process. Liver transplant can be performed in selected patients but is limited by organ supply, requires lifelong immunosuppression, and may be complicated by progressive heart and nerve amyloid deposition. Importantly, liver transplant does not alter the natural course of central nervous system amyloid disease. To date, no treatment for ATTR penetrates the CNS. At present there is no FDA approved treatment for ATTR amyloidosis in the US. In Europe, Tafamidis has been approved for treatment of stage 1 ATTR-polyneuropathy since 2012. Tafamidis and Tolcapone bind to the thyroxine binding site of TTR (with different drug-transthyretin interactions) and in so doing stabilizes the tetrameric form of TTR, preventing dissociation and amyloid fibril formation The preclinical and clinical data from a variety of experimental systems support the therapeutic activity of TOLCAPONE in TTR mediated disease.
