Active clinical trials for "Immunoglobulin Light-chain Amyloidosis"

RATIONALE: Biological therapies, such as lenalidomide, may stimulate the immune system in different ways and stop plasma cells from growing. Drugs used in chemotherapy, such as cyclophosphamide and dexamethasone, work in different ways to stop the growth of plasma cells, either by killing the cells or by stopping them from dividing. Giving lenalidomide together with cyclophosphamide and dexamethasone may be an effective treatment for primary systemic amyloidosis. PURPOSE: This phase II trial is studying how well giving lenalidomide together with cyclophosphamide and dexamethasone works in treating patients with primary systemic amyloidosis.

RATIONALE: Drugs such as melphalan, thalidomide, and dexamethasone may be effective in treating patients with primary systemic amyloidosis. PURPOSE: This phase II trial is studying how well giving melphalan together with thalidomide and dexamethasone works in treating patients with primary systemic amyloidosis.

RATIONALE: Chemotherapy plus interferon alfa may be effective for primary systemic amyloidosis. PURPOSE: Phase II trial to study the effectiveness of dexamethasone plus interferon alfa in treating patients who have primary systemic amyloidosis.

This clinical trial studies fludarabine phosphate and total-body radiation followed by donor peripheral blood stem cell transplant and immunosuppression in treating patients with hematologic malignancies. Giving chemotherapy and total-body irradiation before a donor peripheral blood stem cell transplant helps stop the growth of cancer cells. It may also stop the patient's immune system from rejecting the donor's stem cells. When the healthy stem cells from a donor are infused into the patient they may help the patient's bone marrow make stem cells, red blood cells, white blood cells, and platelets. Sometimes the transplanted cells from a donor can make an immune response against the body's normal cells. Giving total-body irradiation together with fludarabine phosphate, cyclosporine, and mycophenolate mofetil before transplant may stop this from happening.

In this multi-center phase III trial, untreated patients diagnosed with AL who are not candidates for stem cell transplant with melphalan 200 mg/m2 are the target population. Stage I and II patients will be eligible. Stage III patients will be enrolled in an ancillary phase II study. Eligible patients will be stratified as cardiac stage I or stage II and then randomized to receive MDex or BMDex. Primary objective is to compare hematologic(clonal) response i.e. the rate of complete response (CR) + partial response (PR) defined according to the criteria of the International Society for Amyloidosis consensus.

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.

In this study the investigators want to find out more about the addition of the antibiotic, doxycycline, to standard anti-amyloid therapy in people with amyloidosis. The investigators want to find out whether doxycycline improves the response to standard anti-amyloid therapy and whether it causes any problems (side effects).

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: 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.
