- Minimum Age: 18 Years
- Maximum Age: None
- Healthy Volunteers: f

Study Arms:
- Cohort A (alisertib, rituximab) (Type: EXPERIMENTAL): Patients receive alisertib PO BID on days 1-7. Patients unable to achieve CR after course 4 also receive rituximab IV on day 1 of courses 5-12. Courses repeat every 21 days in the absence of disease progression or unacceptable toxicity.
- Cohort B (alisertib, rituximab) (Type: EXPERIMENTAL): Patients receive alisertib as in Cohort A. Patients achieving SD or asymptomatic progressive disease after 2 courses also receive rituximab IV on day 1 of courses 3-10. Patients unable to achieve CR by course 4, receive rituximab as in Cohort A. Courses repeat every 21 days in the absence of disease progression or unacceptable toxicity.

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