Supportive medications

• Aspirin 81 or 325 mg (physician discretion) PO once per day as prophylaxis

If no response after 3 cycles of therapy, then patients were escalated to lenalidomide & dexamethasone. Otherwise, treatment continued until progression of disease or unacceptable toxicity.

Variant #2, 25 mg dosing

Study	Evidence
Dispenzieri et al. 2006	Phase II

Chemotherapy

• Lenalidomide (Revlimid) 25 mg PO once per day on days 1 to 21

28-day cycles

If no response after 3 cycles of therapy, then patients were escalated to lenalidomide & dexamethasone. Otherwise, treatment continued with a target of 12 cycles, total.
