Study Arms:
- Rituximab (Type: ACTIVE_COMPARATOR): Rituximab (MabThera®) will be administered for a maximum of 8 infusions at weeks 1, 2, 3, 4 and again at weeks 12, 13, 14, 15 if the first restaging at week 10 (+/- 1 week) shows a partial response with at least more than 25% reduction in sum of product of diameters
- Rituximab plus Lenalidomide (Type: ACTIVE_COMPARATOR): Lenalidomide will be administered as 15 mg flat dose daily, starting 14 days before first and stopping 14 days after last rituximab administration.

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