Efficacy Study of Revlimid® and Low Dose Continuously Administered Melphalan to Treat High Risk MDS

Summary

Angiogenesis increases in higher risk MDS patients and those with proliferative CMML. Angiogenesis is associated with increased risk of leukemic transformation and poorer prognoses. Low dose chemotherapy may have anti-angiogenic properties by targetting the genetically stable endothelial cells. Lenalidomide has been recently shown to be highly effective as monotherapy in low/low-intermediate risk MDS, particularly in the subgroup harboring a 5q- deletion. Lenalidomide has not been well studied in higher risk MDS although there are some reports of lenalidomide's efficacy in RAEB-T and AML. One potential mode of action of lenalidomide is inhibition of angiogenesis. The investigators hypothesize that by combining lenalidomide with low dose melphalan in higher risk MDS the investigators will more effectively block angiogenesis and achieve responses or hematologic improvement in MDS.
