Study Arms:
- Arm I (Type: EXPERIMENTAL): Patients receive oral sorafenib tosylate twice daily and oral letrozole, anastrozole, or exemestane once daily on days 1-28. Treatment repeats every 28 days in the absence of disease progression or unacceptable toxicity.
- Arm II (Type: ACTIVE_COMPARATOR): Patients receive oral placebo twice daily and oral letrozole, anastrozole, or exemestane once daily on days 1-28. Treatment repeats every 28 days in the absence of disease progression or unacceptable toxicity.

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