Summary
Brief summary (as posted)
This research study seeks to find new ways to treat people with Waldenstrom's Macroglobulinemia (WM). The study is for participants with slow growing WM who otherwise might not need therapy for at least 3-6 months. Simvastatin is a drug approved by the FDA for lowering cholesterol. In test tube studies the study drug appears to have direct anti-cancer effect against WM tumor cells and mast cells.

Primary outcomes (2)
- measure
- Objective Response Rate
- timeFrame
- Assessed at month 1 and 3 and thereafter every 3 months while on therapy. Median duration on treatment was 6 months (range 1-24 months).
- description
- Objective response is defined as achieving partial response or better on therapy based on the Consensus Panel Recommendations from the 2nd and 3rd International Workshop on WM \[Weber et al, 2003; Kimby et al, 2005\]. Complete Response (CR): Complete disappearance of serum monoclonal (SM) Immunoglobulin (Ig) E (IgE), measured centrally; resolution of adenopathy/organomegaly upon physical exam and computerized tomography (CT) scan; lymph nodes =\<1.5 centimeters; absence of malignant cell by bone marrow histologic examination. Partial Response (PR): a \>=50% reduction from baseline in the SM IgM concentration. Minor Response (MR): \>=25%, but a \<50% reduction of SM IgM from baseline.
