Study Arms:
- Group 1 (Type: EXPERIMENTAL): Patients receive oral lenalidomide on days 1-21. Treatment repeats every 28 days for up to 7 courses in the absence of disease progression or unacceptable toxicity. Patients receive pneumococcal polyvalent vaccine intramuscularly (IM) 14 days prior to beginning lenalidomide and again in approximately 2 months (after the first dose of the vaccine).
- Group 2 (Type: EXPERIMENTAL): Patients receive lenalidomide as in group 1. Patients receive pneumococcal polyvalent vaccine IM approximately 45 days after beginning lenalidomide and again in approximately 2 months (after the first dose of the vaccine).

Based on this trial design, predict the completion outcome and termination type (if applicable).

Answer: outcome: complete
