Arms of the Study
Arm 1
Experimental
Treatment (clarithromycin, dexamethasone, lenalidomide)
Patients receive clarithromycin orally (PO) twice daily and dexamethasone PO once a week. Treatment with clarithromycin and dexamethasone continues for up to 1 year in the absence of disease progression or unacceptable toxicity. Patients also receive lenalidomide PO once daily on days 1-14. Courses with lenalidomide repeat every 21 days in the absence of disease progression or unacceptable toxicity. Lenalidomide is taken 4 hours or more after last dose of daily clarithromycin. NOTE: *After one year of treatment, dexamethasone is tapered for an additional 4 weeks.
