Study Arms:
- Previously untreated (Type: EXPERIMENTAL): Patients enrolled with untreated, newly diagnosed mantle cell lymphoma (MCL) or chronic lymphocytic leukemia (CLL) \[Group I\].~Patients receive vorinostat PO on days 1-14, cladribine IV over 2 hours on days 1-5, and rituximab IV on day 3 (weekly for the first course). Treatment repeats every 28 days for up to 6 courses in the absence of disease progression or unacceptable toxicity.
- Relapsed (Type: EXPERIMENTAL): Patients with relapsed disease including indolent Non-Hodgkins Lymphoma (NHL), mantle cell lymphoma (MCL), or chronic lymphocytic leukemia (CLL) \[Group II\].~Patients receive vorinostat PO on days 1-14, cladribine IV over 2 hours on days 1-5, and rituximab IV on day 3 (weekly for the first course). Treatment repeats every 28 days for up to 6 courses in the absence of disease progression or unacceptable toxicity.

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