Study Arms:
- Treatment (combination chemotherapy) (Type: EXPERIMENTAL): Patients receive mitoxantrone hydrochloride IV over 30 minutes and ixabepilone IV over 3 hours on day 1 and oral prednisone twice daily on days 1-21. Treatment repeats every 21 days for ≥ 3 courses in the absence of disease progression or unacceptable toxicity.

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