Study Arms:
- Treatment (Pentostatin, Alemtuzumab, Rituximab) (Type: EXPERIMENTAL): Course 1: Patients receive:~* 2 mg/m\^2 pentostatin IV on days 8 and 22;~* 3 mg alemtuzumab subcutaneously (SC) on day 3;~* 10 mg alemtuzumab SC on day 4;~* 30 mg alemtuzumab SC on days 5, 8, 10, 12, 15, 17, 19, 22, 24, 26, 29, 31, and 33;~* 20 mg/m\^2 rituximab IV on days 1, 3, 5, 8, 10, 12, 15, 17, 19, 22, 24, 26, 29, 31, and 33;~* 6 mg Sargramostim (GM-CSF) SC on days 10-14. Patients then proceed to course 2.~Courses 2 and 3: Patients receive:~* 2 mg/m\^2 pentostatin IV on days 1 and 15;~* 30 mg alemtuzumab SC on days 1, 3, 5, 8, 10, 12, 15, 17, 19, 22, 24, and 26;~* 20 mg/m\^2 rituximab IV on days 1, 3, 5, 8, 10, 12, 15, 17, 19, 22, 24, and 26;~* 6 mg GM-CSF SC on days 3-7. After completion of course 2, patients with a complete response proceed to observation. Patients with a partial response or stable disease receive another course of therapy (course 3).

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