Study Arms:
- Arm 1 - Thalidomide once daily (Type: EXPERIMENTAL): Patients receive oral thalidomide 100 mg at bedtime once daily for 4 weeks, then progresses to 200 mg at bedtime for 4 weeks, then progresses to 300 mg at bedtime (maintenance dose).
- Arm 2 - Placebo once daily (Type: PLACEBO_COMPARATOR): Patients receive oral placebo once daily.

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