Study Arms:
- Induction then Sorafenib (Type: EXPERIMENTAL): Induction: All patients receive oral sorafenib twice daily on days 1-28. Treatment continues for 2 cycles in the absence of disease progression or unacceptable toxicity. Patients with stable disease proceed to randomization. Patients with responding disease continue to receive sorafenib for up to 1 year in the absence of disease progression.~Randomization: Patients with stable disease after the induction treatment were randomized to either the sorafenib arm or the placebo arm. Patients on the sorafenib arm receive sorafenib twice daily for up to 1 year in the absence of disease progression or unacceptable disease.
- Induction then Placebo then Sorafenib (Type: PLACEBO_COMPARATOR): Induction: All patients receive oral sorafenib twice daily on days 1-28. Treatment continues for 2 cycles in the absence of disease progression or unacceptable toxicity. Patients with stable disease proceed to randomization. Patients with responding disease continue to receive sorafenib for up to 1 year in the absence of disease progression.~Randomization: Patients with stable disease after the induction treatment were randomized to either the sorafenib arm or the placebo arm. Patients on the placebo arm receive oral placebo twice daily for up to 1 year in the absence of disease progression or unacceptable toxicity. Patients on the placebo arm who develop disease progression within 1 year after randomization may cross over to sorafenib arm.
- Induction, not randomized (Type: OTHER): Induction: All patients receive oral sorafenib twice daily on days 1-28. Treatment continues for 2 cycles in the absence of disease progression or unacceptable toxicity.~Post-induction: Patients with responding disease or disease progression were not randomized in Step 2. Patients with responding disease continue to receive sorafenib for up to 1 year in the absence of disease progression, while patients with disease progression were removed from the study.

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