Active clinical trials for "Amyloidosis"

The goal of this clinical trial is to determine the toxicity and also the efficacy of a treatment that includes the following treatment: Two medications, bortezomib and dexamethasone (or BD), followed by autologous stem cell transplantation, and a prolonged course of treatment with bortezomib and dexamethasone after transplantation. This type of treatment has been very effective in multiple myeloma. However, there is little experience with this treatment in patients who have Monoclonal Immunoglobulin Deposition Disease (MIDD) or amyloidosis. The investigators and others have treated patients who have MIDD and amyloidosis with bortezomib and autologous stem cell transplantation and have had success with this treatment. But the combination of autologous transplant with BD given before and after the transplant is a new way of treating these diseases, which the investigators believe will be very effective.

RATIONALE: Giving melphalan and bortezomib before and after a stem cell transplant stops the growth of abnormal cells by stopping them from dividing or killing them. Giving colony-stimulating factors and certain chemotherapy drugs, helps stem cells move from the bone marrow to the blood so they can be collected and stored. Chemotherapy and monoclonal antibody therapy is then given to prepare the bone marrow for the stem cell transplant. The stem cells are then returned to the patient to replace the blood-forming cells that were destroyed by the chemotherapy. PURPOSE: This phase II trial is studying how well giving melphalan together with bortezomib followed by stem cell transplant works in treating patients with primary systemic amyloidosis.

The treatment with oral melphalan and prednisone has been recommended as standard treatment of AL amyloidosis but the results are rather disappointing. Another therapeutic option is pulsed high-dose dexamethasone + melphalan (Mel-Dex) with more encouraging results regarding the achievement of a faster disease response and higher rates of haematological remission. In the last 5 - 10 years, promising treatment outcomes after therapy with high-dose melphalan and autologous stem cell support have been reported by several groups but only highly selected patients are eligible for this treatment. Lenalidomide has been shown to be effective in phase II and III trials in MM patients. Because of the relationship to MM, Lenalidomide is a promising therapeutic option also for patients with AL amyloidosis. The addition of Lenalidomide to Mel-Dex could improve rate of complete response (CR) and organ response in patients not eligible for or refused high-dose chemotherapy.

This open-label trial will evaluate the use of lenalidomide; melphalan; and dexamethasone (MDR) to treat newly diagnosed or relapsed AL amyloidosis, over the course of nine 28-day cycles.

RATIONALE: Biological therapies, such as CC-4047, may stimulate the immune system in different ways and stop cancer cells from growing. Dexamethasone and CC-4047 may stop the growth of cancer cells by blocking blood flow to the cancer. Giving CC-4047 together with dexamethasone may kill more cancer cells. PURPOSE: This phase II trial is studying how well giving CC-4047 together with dexamethasone works in treating patients with relapsed or refractory multiple myeloma or amyloidosis.

RATIONALE: Drugs used in chemotherapy such as melphalan work in different ways to stop cancer cells from dividing so they stop growing or die. Combining chemotherapy with donor peripheral stem cell transplantation may allow the doctor to give higher doses of chemotherapy drugs and kill more cancer cells. PURPOSE: This phase II trial is studying how well giving melphalan together with autologous stem cell transplantation works in treating patients with multiple myeloma or primary systemic amyloidosis.

The main objective of this study is to evaluate the safety and efficacy of NC-503 compared to placebo in patients with secondary (AA) amyloidosis using a composite assessment of clinical improvement/worsening of both renal and gastrointestinal functions.

RATIONALE: Drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. Combining chemotherapy with peripheral stem cell transplant may allow the doctor to give higher doses of chemotherapy drugs and kill more cancer cells. PURPOSE: This phase II trial is studying how well chemotherapy and peripheral stem cell transplant work in treating patients with multiple myeloma or primary systemic amyloidosis.

To evaluate the safety and tolerability, as well as the pharmacokinetic and pharmacodynamic profiles of single and multiple doses of Eplontersen administered subcutaneously to healthy volunteers and patients with Hereditary Transthyretin-Mediated Amyloidosis (hATTR ).

This is a single-arm, open-label, multicenter study designed to determine the effect of tafamidis meglumine on TTR stabilization as well as tafamidis meglumine safety, tolerability and efficacy in ATTR-PN patients in China. Approximately 10-15 participants are planned to be enrolled. All enrolled participants will receive oral tafamidis meglumine 20 mg soft capsules once daily for 72 weeks (18 months).
