Study Arms:
- Group 1 (Type: ACTIVE_COMPARATOR): Both groups will receive an intravenous chemotherapeutic drug (carboplatin). The first study group (n=6) will receive bevacizumab, the antiangiogenic agent for three weeks, then dexamethasone for three weeks.
- Group 2 (Type: ACTIVE_COMPARATOR): Both groups will receive an intravenous chemotherapeutic drug (carboplatin). The second study group (n=6) will receive dexamethasone for 3 weeks, then switch to bevacizumab, the antiangiogenic agent, for 3 weeks.

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