Study Arms:
- Group I (Type: EXPERIMENTAL): Patients receive rituximab IV on days 1, 8, 15, and 22 and oral beta-glucan once daily on days 1-28 (days 8-28 of course 1). Treatment repeats every 42 days for 4 courses.
- Group II (Type: EXPERIMENTAL): Patients receive rituximab IV on days 1, 4, 8, 15, and 22 and oral beta-glucan once daily on days 8-28. Beginning on day 42, patients with responding disease may receive monthly rituximab prophylaxis.

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