Multiple Myeloma Clinical Trial
Melphalan, Lenalidomide, and Dexamethasone in Treating Patients With Primary Systemic Amyloidosis
Summary
RATIONALE: Drugs used in chemotherapy, such as melphalan and dexamethasone, work in different ways to stop the growth of abnormal plasma cells, either by killing the cells or by stopping them from dividing. Biological therapies, such as lenalidomide, may stimulate the immune system in different ways and stop the abnormal plasma cells from growing. Giving melphalan together with lenalidomide and dexamethasone may be an effective treatment for primary systemic amyloidosis.
PURPOSE: This phase II trial is studying the side effects and how well giving melphalan together with lenalidomide and dexamethasone works in treating patients with primary systemic amyloidosis.
Full Description
OBJECTIVES:
Primary
To determine the tolerability and safety of melphalan, lenalidomide, and dexamethasone, in terms of toxicity, in patients with primary systemic amyloidosis.
To determine the hematologic response rate in patients treated with this regimen.
Secondary
To assess organ response in patients treated with this regimen.
OUTLINE: Patients receive oral lenalidomide once daily on days 1-21, oral melphalan once daily on days 1-4, and oral dexamethasone once on days 1, 8, 15, and 22. Treatment repeats every 28 days for up to 12 months in the absence of disease progression or unacceptable toxicity.
After completion of study therapy, patients are followed every 3 months until disease progression and then annually thereafter.
