Primary (safety) endpoint reached

This single arm study will assess the feasibility of using Avastin plus platinum-based chemotherapy (cisplatin-gemcitabine or carboplatin-paclitaxel) in patients with advanced or recurrent squamous non-small cell lung cancer who have not received prior chemotherapy. Patients will receive preventive radiation, followed by one cycle of chemotherapy alone and 5 cycles of chemotherapy in combination with Avastin (15mg/kg iv on day 1 of each 3 weekly cycle), followed by Avastin alone for a maximum total treatment period with Avastin of 12 months. The anticipated time on study treatment is 3-12 months, and the target sample size is <100 individuals.

Inclusion Criteria:

• adult patients, >=18 years of age;
• documented squamous non-small cell lung cancer;
• stage IIIb with pleural or pericardial effusion, stage IV, or recurrent disease;
• suitable for platinum-based treatment as first line chemotherapy.

Exclusion Criteria:

• prior systemic anti-tumor therapy;
• prior radiotherapy for treatment of patient's current stage of disease;
• other primary tumors within last 5 years, except for controlled limited basal cell or squamous cancer of the skin, or cancer in situ of the cervix;
• major surgery, open biopsy or significant traumatic injury within 28 days prior to randomization.
