Study Arms:
- Arm I (Type: EXPERIMENTAL): Patients receive bevacizumab IV over 30-90 minutes on day 15 and oral erlotinib on days 1-28. All subsequent courses patients receive oral erlotinib on days 1-21. Courses repeat every 21 days in the absence of disease progression or unacceptable toxicity.
- Arm II (Type: EXPERIMENTAL): Patients receive bevacizumab IV over 30-90 minutes on day 1 and oral erlotinib on days 1-28. All subsequent courses patients receive oral erlotinib on days 1-21. Courses repeat every 21 days in the absence of disease progression or unacceptable toxicity.

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