Study Arms:
- Arm I (Type: EXPERIMENTAL): Patients receive gemcitabine hydrochloride\* IV on days 1 and 8 OR pemetrexed disodium\* IV on day 1. Patients also receive carboplatin IV on day 1 and oral celecoxib twice daily on days 1-21.
- Arm II (Type: ACTIVE_COMPARATOR): Patients receive gemcitabine hydrochloride\* OR pemetrexed disodium\* and carboplatin as in arm I. Patients also receive oral placebo twice daily on days 1-21.

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