Group I (consolidation phase)
Group II (consolidation phase)
Patients receive oral lenalidomide once daily on days 1-14. Treatment repeats every 21 days for 8 courses in the absence of disease progression or unacceptable toxicity.
Patients receive lenalidomide as in group I. Patients also receive rituximab IV once on the day before the start of lenalidomide and then once between days 25-30, 50-55, and 75-80 for a total of 4 doses in the absence of disease progression or unacceptable toxicity.
