Lenalidomide Intensification in Patients With Serologic/Asymptomatic Progression of Multiple Myeloma While on Lenalidomide Maintenance

patients will begin therapy with lenalidomide 25 mg daily, 21 days out of a 28 day schedule. All patients will be evaluated monthly after every cycle. The dose will be adjusted downward in response to side effects and according to specific guidelines. Symptomatic POD occurring at any time during the study will result in removal of the patient from the study. After 2 cycles of lenalidomide, patients with at least stable disease (SD) will continue lenalidomide indefinitely until asymptomatic POD, at which time dexamethasone will be added at a dose of 40mg weekly. On the other hand, patient with asymptomatic POD after 2 cycles of lenalidomide will have dexamethasone added at a dose of 40 mg weekly. Patients with any type of POD after any cycle that includes dexamethasone will be taken off study. Patients can remain on study on lenalidomide or lenalidomide/dexamethasone indefinitely as long as they do not have POD as stated above and they tolerate the treatment.
