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.
|Condition or disease||Intervention/treatment||Phase|
|Multiple Myeloma||Drug: dexamethasone Drug: lenalidomide Drug: melphalan||Phase 2|
- 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.
- 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.

- Number of Participants With Hematologic Response [ Time Frame: one year ]
Complete hematologic response: Absence of detectable monoclonal protein in serum or urine by immunofixation electrophoresis, bone marrow biopsy with less than 5% plasma cells without clonal dominance of kappa or lambda isotype, and normal serum free light chain assay.
Partial hematologic response: Amyloid patients have highly individualized measures of disease burden. For patients with detectable and quantifiable monoclonal marrow plasmacytosis, a reduction of 50% or more in plasma cells as a percentage of nucleated bone marrow cells. For patients with a detectable monoclonal peak on serum or urine protein electrophoresis, a reduction in the peak height of 50% or more. For patients with quantifiable urinary kappa or lambda chain concentration, a 50% reduction in daily light chain excretion (concentration x 24 hour urine volume). For patients with an elevated serum free light chain assay, reduction of 50% or more.
- Number of Organs Improved or Stable Based on Description Below: [ Time Frame: one year ]
Renal response - > 50% decrease in daily 24 hour proteinuria, without worsening renal insufficiency.
Hepatic response - decrease of 2 centimeters or more of the liver span and/or decrease of the alkaline phosphatase by 50% if elevated at baseline.
Cardiac response - decrease of 2 millimeters or more in mean left ventricular wall thickness in patients with baseline wall thickness > 11 mm or a decrease in New York Heart Association heart failure class.
Autonomic nervous system response - resolution of orthostatic vital signs and symptoms, and resolution of symptoms of gastric atony or of functional ileus.
Gastrointestinal response - a greater than one grade improvement in diarrhea due to biopsy proven amyloid.
Peripheral nervous system response - resolution of clinical signs of peripheral neuropathy.
- Number of Participants Removed From Study Due to Toxicities [ Time Frame: One year ]Number of study participants removed from study treatment due to toxicities
