Clinical Trial: CC-5013 With or Without Dexamethasone in Treating Patients With Primary Systemic Amyloidosis
Study Status: Completed
Recruit Status: Completed
Study Type: Interventional
Official Title: A Phase II Trial of the Immunomodulatory Drug CC-5013 for Patients With AL Amyloidosis
Brief Summary:
RATIONALE: Drugs such as CC-5013 and dexamethasone may be effective in treating primary systemic amyloidosis.
PURPOSE: This phase II trial is studying CC-5013 to see how well it works with or without dexamethasone in treating patients with primary systemic amyloidosis.
Detailed Summary:
OBJECTIVES:
Primary
- Determine the tolerability of CC-5013 in patients with primary systemic (AL) amyloidosis.
- Determine the objective hematologic response rate in patients treated with this drug.
- Determine amyloid organ disease response in patients treated with this drug.
Secondary
- Determine hematologic and amyloid organ disease response in patients who do not achieve a response to CC-5013 alone and are subsequently treated with CC-5013 and dexamethasone.
- Determine the toxicity of CC-5013 in combination with dexamethasone in these patients.
OUTLINE: Patients receive oral CC-5013 once daily on days 1-21. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity. Patients not achieving a hematologic response continue to receive CC-5013 as before and also receive oral dexamethasone twice daily on days 1-4, 9-12, and 17-20 of every other 28-day course for up to 6 courses of combination therapy. Patients who maintain a hematologic response after 6 courses of combination therapy may receive CC-5013 alone in the absence of disease progression or unacceptable toxicity. Patients not achieving a hematologic response after the initiation of dexamethasone are removed from the study.
Patients are followed annually.
PROJECTED ACCRUAL: A total of 15-25 patients will be accrued for this study within 5-12.5 months.

Current Primary Outcome:
- Number of Patients Removed From Study Treatment Due to Toxicities [ Time Frame: 1 year ]
- Number of Patients With Hematologic Response With Single-agent CC-5013 [ Time Frame: 3 months ]
Complete response = Absence of detectable monoclonal protein in serum or urine by immunofixation electrophoresis, less than 5% plasma cells on bone marrow biopsy without clonal dominance of kappa or lambda isotype, and normal serum free light chain assay.
Partial response= 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 in 24 hour urine.
For patients with an elevated serum free light chain assay, a reduction of 50% or more.
Original Primary Outcome:
Current Secondary Outcome: Number of Patients Who Received Both CC-5013 and Dexamethasone and Had a Hematologic Response [ Time Frame: 1 year ]
