The treatment of light-chain (AL) amyloidosis is directed against the plasma cells that produce the light-chain forming the amyloid deposits. The plasma cells can be killed and their growth can be stopped by drugs used in chemotherapy, such as cyclophosphamide, steroids, such as dexamethasone, and drugs that stimulate the immune system, such as lenalidomide. The present trial studies the efficacy and safety of the combination of cyclophosphamide, lenalidomide and dexamethasone in patients with AL amyloidosis who were previously treated and need further therapy.
