25 participants in 1 patient group

Lenalidomide and Dexamethasone

Experimental group

Description:

Lenalidomide 25mg by mouth (PO) once daily (QD) on Days 1-21 of each 28 day cycle; When creatinine (CrCl) clearance \<60 mL/min, the initial dose was 10mg and the dose could be increased to 15mg after 2 cycles if the investigator judged therapeutic effect was insufficient and tolerability was acceptable. Dexamethasone 40 mg by PO once QD on days 1-4, 9-12 and 17-20 of each 28 day cycle for the first 4 cycles and Days 1-4 for the remaining cycles beginning at Cycle 5.

Treatment:

Drug: Lenalidomide

Drug: Dexamethasone
