A Study of Avastin (Bevacizumab) in Combination With Thoracic Radiation and Chemotherapy in Patients With Advanced Non-Squamous Non-Small Cell Lung Cancer.

An Open Label Study to Establish the Preferred Dose and to Assess Safety and Overall Response Rate of Avastin in Combination With Concomitant Thoracic Radiation and Chemotherapy (Cisplatin and Etoposide) in Locally Advanced Unresectable Non-squamous Non-small Cell Lung Cancer.

This single arm study will evaluate the feasibility of treatment with 2 dose levels of Avastin in combination with concurrent thoracic radiation and chemotherapy in patients with locally advanced unresectable non-squamous non-small cell lung cancer. Two cohorts of patients will receive 3 cycles of Avastin treatment (7.5mg/kg and 15mg/kg iv every 3 weeks, respectively), concurrently with thoracic radiation and chemotherapy (cisplatin and etoposide). Once a preferred dose has been established, this dose will be applied to a 3rd cohort, who will then receive maintenance treatment with Avastin as a single agent for 6 additional cycles. The anticipated time on study treatment is <3 months for cohorts 1 and 2, and 3-12 months for cohort 3, and the target sample size is <100 individuals.
